Valve is practically singlehandedly dragging the Linux ecosystem forward in areas that nobody else wanted to touch.
They needed Windows games to run on Linux so we got massive Proton/Wine advancements. They needed better display output for the deck and we got HDR and VRR support in wayland. They also needed smoother frame pacing and we got a scheduler that Zuck is now using to run data centers.
Its funny to think that Meta's server efficiency is being improved because Valve paid Igalia to make Elden Ring stutter less on a portable Linux PC. This is the best kind of open source trickledown.
One would've expected one of the many desktop-oriented distros (some with considerable funding, even) to have tackled these things already, but somehow desktop Linux has been stuck in the awkward midway of "it technically works, just learn to live with the rough edges" until finally Valve took initiative. Go figure.
That isn't it. Generally whatever the majority of users tend to use that where the majority of focus goes.
The vast majority of people that were using Linux on the desktop were either hobbyists, developers or people that didn't want to run proprietary software for whatever reason. These people generally didn't care about HDR, VRR, Wayland and all the other gumpf mentioned. So this stuff didn't get fixed.
Please don't erase all the groundwork they've done over the years to make it possible for these later enhancements to happen. It wasn't like they were twiddling their thumbs this whole time!
That's not my intention at all. It's just frustrating how little of it translates to impact that's readily felt by end users, including those of us without technical inclination.
There's far more of that, starting with the lack of a stable ABI in gnu/linux distros. Eventually Valve or Google (with Android) are gonna swoop in with a user-friendly, targetable by devs OS that's actually a single platform
I don't have a whole lot of faith in Google, based on considerable experience with developing for Android. Put plainly, it's a mess, and even with improvements in recent years there's enough low-hanging fruit for improving its developer story that much of it has fallen off the tree and stands a foot thick on the ground.
The enterprise distros do provide that, somewhat.
That's why, RHEL for example, has such a long support lifecycle. It's so you can develop software targeting RHEL specifically, and know you have a stable environment for 10+ years. RHEL sells a stable (as in unchanging) OS for x number of years to target.
And if you want to follow the RHEL shaped bleeding edge you can develop on latest Fedora. I'll often do this, develop/package and Fedora and then build on RHEL as well.
Ubuntu LTS is currently on track to be that. Both in the server and desktop space, in my personal experience it feels like a rising number of commercial apps are targeting that distro specifically.
It’s not my distribution of choice, but it’s currently doing exactly what you suggest.
I just installed Ubuntu again after a few years, and it’s striking how familiar the pain points are—especially around graphics. If Ubuntu LTS is positioning itself as the standard commercial Linux target, it has to clearly outperform Windows on fundamentals, not just ideology. Linux feels perpetually one breakthrough release away from actually displacing it.
The problem with any LTS release is lack of support for newer hardware. Not as much of an issue for an enthusiast or sysadmin who's likely to be using well-supported hardware, but can be a huge one for a more typical end user hoping to run Linux on their recently purchased laptop.
Is that true? I did just that on my newly purchsed laptop in 2023. It was a thinkpad though.
Isn't that the steam linux runtime? Games linked against the runtime many years ago still run on modern distros.
Over time they're going to touch things that people were waiting for Microsoft to do for years. I don't have an example in mind at the moment, but it's a lot better to make the changes yourself than wait for OS or console manufacturer to take action.
I was at Microsoft during the Windows 8 cycle. I remember hearing about a kernel feature I found interesting. Then I found linux had it for a few years at the time.
I think the reality is that Linux is ahead on a lot of kernel stuff. More experimentation is happening.
I was surprised to hear that Windows just added native NVMe which Linux has had for many years. I wonder if Azure has been paying the SCSI emulation tax this whole time.
Probably, most of stuff you see in Windows Server these days is backported from Azure improvements.
It was always wild to me that their installer was just not able to detect an NVMe drive out of the box in certain situations. I saw it a few times with customers when I was doing support for a Linux company.
when the hood is open for anyone to tinker, lots of little weirdos get to indulge their ideas. Sometimes those are ideas are even good!
Never underestimate the efficiency and amazing results of autistic focus.
"Now that's curious..."
Passion over paycheques
yeah, but you have IO Completion Ports…
IO_Uring is still a pale imitation :(
If that were true then presumably Microsoft wouldn't have ported it to Windows:
That argument holds no water. IOUring is essential for the performance of some modern POSIX programs.
You can see shims for fork() to stop tanking performance so hard too. IOUring doesnt map at all onto IOCP, at least the windows subtitute for fork has “ZwCreateProcess“ to work from. IOUring had nothing.
IOCP is much nicer from a dev point of view because your program can be signalled when a buffer has data on it but also with the information of how much data, everything else seems to fail at doing this properly.
The CQE for e.g. a successful read(2) operation will have the number of bytes read in the `res` field.
io_uring does more than IOCP. It's more like an asynchronous syscall interface that avoids the overhead of directly trapping into the kernel. This avoids some overheads IOCP cannot. I'm rusty on the details but the NT kernel has since introduced an imitation: https://learn.microsoft.com/en-us/windows/win32/api/ioringap...
IOCP is great and was ahead of Linux for decades, but io_uring is also great. It's a different model, not a poor copy.
I think they are a bit different - in the Windows kernel, all IO is asynchronous on the driver level, on Linux, it's not.
io_uring didn't change that, it only got rid of the syscall overhead (which is still present on Windows), so in actuality they are two different technical solutions that affect different levels of the stack.
In practice, Linux I/O is much faster, owing in part to the fact that Windows file I/O requires locking the file, while Linux does not.
io_uring makes synchronous syscalls async simply by offloading them to a pool of kernel threads, just like people have done for decades in userspace.
Yeah and Linux is waaay behind in other areas. Windows had a secure attention sequence (ctrl-alt-del to login) for several decades now. Linux still doesn't.
Linux (well, more accurately, X11), has had a SAK for ages now, in the form of the CTRL+ALT+BACKSPACE that immediately kills X11, booting you back to the login screen.
I personally doubt SAK/SAS is a good security measure anyways. If you've got untrusted programs running on your machine, you're probably already pwn'd.
The "threat model" (if anyone even called it that) of applications back then was bugs resulting in unintended spin-locks, and the user not realizing they're critically short on RAM or disk space.
This setup came from the era of Windows running basically everything as administrator or something close to it.
The whole windows ecosystem had us trained to right click on any Windows 9X/XP program that wasn’t working right and “run as administrator” to get it to work in Vista/7.
Is that something Linux needs? I don’t really understand the benefit of it.
The more powerful form is the UAC full privilege escalation dance that Win 7+(?) does, which is a surprisingly elegant UX solution.
1. Snapshot the desktop
2. Switch to a separate secure UI session
3. Display the snapshot in the background, greyed out, with the UAC prompt running in the current session and topmost
It avoids any chance of a user-space program faking or interacting with a UAC window.
Clever way of dealing with the train wreck of legacy Windows user/program permissioning.
My only experience with non-UAC endpoint privilege management was BeyondTrust and it seemed to try to do what UAC did but with a worse user experience. It looks like the Intune EPM offering also doesn't present as clear a delineation as UAC, which seems like a missed opportunity.
>Display the snapshot in the background, greyed out,
Is there an offset. I could have sworn things always seemed offset to the side a little.
One of the things Windows did right, IMO. I hate that elevation prompts on macOS and most linux desktops are indistinguishable from any other window.
It's not just visual either. The secure desktop is in protected memory, and no other process can access it. Only NTAUTHORITY\System can initiate showing it and interact with it any way, no other process can.
You can also configure it to require you to press CTRL+ALT+DEL on the UAC prompt to be able to interact with it and enter credentials as another safeguard against spoofing.
I'm not even sure if Wayland supports doing something like that.
It made a lot more sense in the bygone years of users casually downloading and running exe's to get more AIM "smilies", or putting in a floppy disk or CD and having the system autoexec whatever malware the last user of that disk had. It was the expected norm for everybody's computer to be an absolute mess.
These days, things have gotten far more reasonable, and I think we can generally expect a linux desktop user to only run software from trusted sources. In this context, such a feature makes much less sense.
It's useful for shared spaces like schools, universities and internet cafes. The point is that without it you can display a fake login screen and gather people's passwords.
I actually wrote a fake version of RMNet login when I was in school (before Windows added ctrl-alt-del to login).
I got the teacher's password and then got scared and deleted all trace of it.

And behind on a lot of stuff. The Microsoft's ACLs are nothing short of one of the best designed permission systems there are.
On the surface, they are as simple as Linux UOG/rwx stuff if you want it to be, but you can really, REALLY dive into the technology and apply super specific permissions.
> The Microsoft's ACLs are nothing short of one of the best designed permission systems there are.
You have a hardened Windows 11 system. A critical application was brought forward from a Windows 10 box but it failed, probably a permissions issue somewhere. Debug it and get it working. You can not try to pass this off to the vendor, it is on you to fix it. Go.
and why is it not on the vendor of the critical application?
Because they aren't allowed on the system where it is installed, and also they don't deal with hardened systems.
Procmon.exe. Give me 2 minutes. You make it sound like it's such a difficult thing to do. It literally will not take me more than 2 minutes to tell you exactly where the permission issue is and how to fix it.
Procmon won't show you every type of resource access. Even when it does, it won't tell you which entity in the resource chain caused the issue.
And then you get security product who have the fun idea of removing privileges when a program creates a handle (I'm not joking, that's a thing some products do). So when you open a file with write access, and then try to write to the file, you end up with permission errors durig the write (and not the open) and end up debugging for hours on end only to discover that some shitty security product is doing stupid stuff...
Granted, thats not related to ACLs. But for every OK idea microsoft had, they have dozen of terrible ideas that make the whole system horrible.
Especially when the permission issue is up the chain from the application. Sure it is allowed to access that subkey, but not the great great grandparent key.
And they work on everything. You can have a mutex, a window handle or a process protected by ACL.
The file permission system on Windows allows for super granular permissions, yes; administrating those permissions was a massive pain, especially on Windows file servers.
Do you have any favorite docs or blogs on these? Reading about one of the best designed permissions systems sounds like a fun way to spend an afternoon ;)
You have ACLs on linux too
ACLs in Linux were tacked on later; not everything supports them properly. They were built into Windows NT from the start and are used consistently across kernel and userspace, making them far more useful in practice.
Also, as far as I know Linux doesn't support DENY ACLs, which Windows does.
Yes it does.
since when?
Since some of us could be bothered reading docs. Give it a try and see how it works out for you.
Some of us can! I certainly enjoy doing it, and according to "man 5 acl" what you assert is completely false. Unless you have a particular commit or document from kernel.org you had in mind?
> Each of these characters is replaced by the - character to denote that a permission is absent in the ACL entry.
Wouldn't the o::--- default ACL, like mode o-rwx, deny others access in the way you're describing?
[deleted]
Haha, sure. Sorry, it's not you, it's the ACLs (and me nerves). Have you tried configuring NFSv4 ACLs on Linux? Because kernel devs are against supporting them, you either use some other OS or have all sorts of "fun". Also, not to be confused with all sorts of LSM based ACLs... Linux has ACLs in the most ridiculous way imaginable...
Not by default.
Not as extensive as in Windows.
What's your point?
Oh yeah for sure. Linux is amazing in a computer science sense, but it still can't beat Windows' vertically integrated registry/GPO based permissions system. Group/Local Policy especially, since it's effectively a zero coding required system.
Ubuntu just recently got a way to automate its installer (recently being during covid). I think you can do the same on RHEL too. But that's largely it on Linux right now. If you need to admin 10,000+ computers, Windows is still the king.
Debian (and thus Ubuntu) has full support for automated installs since the 90's. It's built into `dpkg` since forever. That include saving or generating answer to install time questions, PXE deployment, ghosting, CloudInit and everything. Then stuff like Ansible/Puppet have been automating deployment for a long time too. They might have added yet another way of doing it, but full stack deployment automation has been there for as long as Ubuntu existed.
> Ubuntu just recently got a way to automate its installer (recently being during covid).
RH has also had kickstart since basically forever now.
I've been using both preseeds and kickstart professionally for over a decade. Maybe you're thinking of the graphical installer?
> Ubuntu just recently got a way to automate its installer (recently being during covid). I think you can do the same on RHEL too. But that's largely it on Linux right now. If you need to admin 10,000+ computers, Windows is still the king.
What?! I was doing kickstart on Red Hat (want called Enterprise Linux back then) at my job 25 years ago, I believe we were using floppies for that.
Yeah, I have been working on the RHEL and Fedora installer since 2013 and already back then it had a long history almost lost to time - the git history goes all the way back to 1999 (the history was imported from CVS, as it predates Git) and that actually only cover the first graphical interface - it had automated installation support via kickstart and a text interface long before that, but the commit history has been apparently lost. And there seems to have been even some earlier distict installer before Anaconda, that likely also supported some sort of automated install.
BTW, we managed to get the earlies history of the project written down here by one of the earliest contributors for anyone who might be interested:
Note how some commands were introduced way back in the single digit Fedora/Fedora Core age - that was from about 2003 to 2008. Latest Fedora is Fedora 43. :)
Still the king but developing/testing/debugging group policy issues is a miserable experience.
I always found it straight forward. Never had an issue and I've implemented my fair share on thousands on devices and servers.
Not an implementer of group policy, more of a consumer. There are 2 things that I find extremely problematic about them in practice.
- There does not seem to be a way to determine which machines in the fleet have successfully applied. If you need a policy to be active before doing deployment of something (via a different method), or things break, what do you do?
- I’ve had far too many major incidents that were the result of unexpected interactions between group policy and production deployments.
> Ubuntu just recently got a way to automate its installer (recently being during covid). I think you can do the same on RHEL too. But that's largely it on Linux right now. If you need to admin 10,000+ computers, Windows is still the king.
1. cloud-init support was in RHEL 7.2 which released November 19, 2015. A decade ago.
2. Checking on Ubuntu, it looks like it was supported in Ubuntu 18.04 LTS in April 2018.
3. For admining tens of thousands of servers, if you're in the RHEL ecosystem you use Satellite and it's ansible integration. That's also been going on for... about a decade. You don't need much integration though other than a host list of names and IPs.
There are a lot of people on this list handling tens of thousands or hundreds of thousands of linux servers a day (probably a few in the millions).
I'm surprised no one has said NixOS yet.
Tbh i'm starting to think that I do not see microsoft being able to keep it's position in the OS market ; with steam doing all the hard work and having a great market to play with ; the vast distributions to choose from, and most importantly how easy it has become to create an operating system from scratch - they not only lost all possible appeal, they seem stuck on really weird fetichism with their taskbar and just didn't provide me any kind of reason to be excited about windows.
Their research department rocks however so it's not a full bash on Microsoft at all - i just feel like they are focusing on other way more interesting stuff
> Tbh i'm starting to think that I do not see microsoft being able to keep it's position in the OS market
It's a big space. Traditionally, Microsoft has held both the multimedia, gaming and lots of professional segments, but with Valve doing a large push into the two first and Microsoft not even giving it a half-hearted try, it might just be that corporate computers continue using Microsoft, people's home media equipment is all Valve and hipsters (and others...) keep on using Apple.
I think that's the most likely way it'll go.
Windows will remain as the default "enterprise desktop." It'll effectively become just another piece of business software, like an ERP.
Gamers, devs, enthusiasts will end up on Linux and/or SteamOS via Valve hardware, creatives and personal users that still use a computer instead of their phone or tablet will land in Apple land.
With the massive adoption of web apps in Enterprise I have seen I would expect Windows to become irelevant or even a liability in business use as well.
Kernel improvements are interesting to geeks and data centers, but open source is fundamentally incompatible with great user experience.
Great UX requires a lot of work that is hard but not algorithmically challenging. It requires consistency and getting many stakeholders to buy in. It requires spending lots of time on things that will never be used by more than 10-20% of people.
Windows got a proper graphics compositor (DWM) in 2006 and made it mandatory in 2012. macOS had one even earlier. Linux fought against Compiz and while Wayland feels inevitable vocal forces still complain about/argue against it. Linux has a dozen incompatible UI toolkits.
Screen readers on Linux are a mess. High contrast is a mess. Setting font size in a way that most programs respect is a mess. Consistent keyboard shortcuts are a mess.
I could go on, but these are problems that open source is not set up to solve. These are problems that are hard, annoying, not particularly fun. People generally only solve them when they are paid to, and often only when governments or large customers pass laws requiring the work to be done and threaten to not buy your product if you don't do it. But they are crucially important things to building a great, widely adopted experience.
…and you are implying that Microsoft Windows 11 is a better example of ”great user experience”?
If you have anything less than perfect vision and need any accessibility features, yes. If you have a High DPI screen, yes. In many important areas (window management, keyboard shortcuts, etc.), yes.
Linux DEs still can't match the accessibility features alone.
yeah, there's layers and layers of progressively older UIs layered around the OS, but most of it makes sense, is laid out sanely, and is relatively consistent with other dialogs.
macOS beats it, but its still better in a lot of ways over the big Linux DEs.
Start menu in the middle of the screen that takes a couple seconds to even load (because it is implemented in React horribly enought to be this slow) only to show adds next to everything is perfect user experience.
Every other button triggering Copilots assures even better UX goodness.
Add to that all the bullshit they have been pushing on their customers lately:
* OS level adds
* invasive AI integration
* dropping support for 40% of their installed base (Windows 10)
* forcing useless DRM/trusted computing hardware - TPM - as a requirement to install the new and objectively worse Windows version version, with even more spying and worse performance (Windows 11)
With that I think their prospects are bleak & I have no idea who would install anything else than Steam OS or Bazzite in the future with this kind of Microsoft behavior.
"It just works" sleep and hibernate.
"Slide left or right" CPU and GPU underclocking.
“it just works” sleep was working, at least on basically every laptop I had the last 10 years…
until the new s2idle stuff that Microsoft and Intel have foisted on the world (to update your laptop while sleeping… I guess?)
From what I read, it was a lot of the prosumer/gamer brands (MSI, Gigabyte, ASUS) implementing their part of sleep/hibernate badly on their motherboards. Which honestly lines up with my experience with them and other chips they use (in my case, USB controllers). Lots of RGB and maybe overclocking tech, but the cheapest power management and connectivity chips they can get (arguably what usually gets used the most by people).
Sleep brokenness is ecosystem-wide. My Thinkpad crashes/freezes during sleep 3 times a week. Lenovo serviced/replaced it 3 times to no avail.
It never really worked in games even with S3 sleep. The new connected standby stuff created new issues but sleeping a laptop while gaming was a roulette wheel. SteamOS and the like actually work, like maybe 1/100 times I've run into an issue. Windows was 50/50.
Sleep and hibernate don't just work on Windows unless Microsoft work with laptop and boards manufacturers to make Windows play nice with all those drivers. It's inevitable that it's hit and miss on any other OS that manufacturers don't care much about. Apple does nearly everything inside their walls, that's why it just works.
“It just works” sadly isn’t true across the Apple Ecosystem anymore.
Liquid Glass ruined multitasking UX on my iPad. :(
Also my macbook (m4 pro) has random freezes where finder becomes entirely unresponsive. Not sure yet why this happens but thankfully it’s pretty rare.
Regardless of how it must be implemented, if this is a desirable feature then this explanation isn’t an absolution of Linux but rather an indictment: its development model cannot consistently provide this product feature.
(And same for Windows to the degree it is more inconsistent on Windows than Mac)
> its development model cannot consistently provide this product feature.
The real problem is that the hardware vendors aren't using its development model. To make this work you either need a) the hardware vendor to write good drivers/firmware, or b) the hardware vendor to publish the source code or sufficient documentation so that someone else can reasonably fix their bugs.
The Linux model is the second one. Which isn't what's happening when a hardware vendor doesn't do either of them. But some of them are better than others, and it's the sort of thing you can look up before you buy something, so this is a situation where you can vote with your wallet.
A lot of this is also the direct fault of Microsoft for pressuring hardware vendors to support "Modern Standby" instead of rather than in addition to S3 suspend, presumably because they're organizationally incapable of making Windows Update work efficiently so they need Modern Standby to paper over it by having it run when the laptop is "asleep" and then they can't have people noticing that S3 is more efficient. But Microsoft's current mission to get everyone to switch to Linux appears to be in full swing now, so we'll see if their efforts on that front manage to improve the situation over time.
The feature itself works. There are just hardware that is buggy and don't support it properly.
That's a vastly different statement.
It's not the development model at fault here. It's the simple fact that Windows makes up nearly the entire user base for PCs. Companies make sure their hardware works with Windows, but many don't bother with Linux because it's such a tiny percentage of their sales.
Except when it doesn't. I can't upgrade my Intel graphics drivers to any newer version than what came with the laptop or else my laptop will silently die while asleep. Internet is full of similar reports from other laptop and graphics manufacturers and none have any solutions that work. The only thing that reliably worked is to restore the original driver version. Doesn't matter if I use the WHQL version(s) or something else.
> Regardless of how it must be implemented, if this is a desirable feature then this explanation isn’t an absolution of Linux but rather an indictment: its development model cannot consistently provide this product feature.
The problem is: the specifications of ACPI are complex, Windows' behavior tends to be pretty much trash and most hardware tends to be trash too (AMD GPUs for example were infamous for not being resettable for years [1]), which means that BIOSes have to work around quirks on both the hardware and software. Usually, as soon as it is reasonably working with Windows (for a varying definition of "reasonably", that is), the ACPI code is shipped and that's it.
Unfortunately, Linux follows standards (or at least, it tries to) and cannot fully emulate the numerous Windows quirks... and on top of that, GPUs tend to be hot piles of dung requiring proprietary blobs that make life even worse.
On my Framework 13 AMD : Sleep just works on Fedora. Sleep is unreliable on Windows; if my fans are all running at full speed while running a game and I close the lid to begin sleeping, it will start sleeping and eventually wake up with all fans blaring.
I don't understand this comment in this context. Both of these features work on my Steam Deck. Neither of them have worked on any Windows laptop my employers have foisted upon me.
That requires driver support. What you're seeing is Microsoft's hardware certification forcing device vendors to care about their products. You're right that this is lacking on Linux, but it's not a slight on the kernel itself.
Both of these have worked fine for the last 15 years or so on all my laptops.
A good one is the shader pre caching with fossilize, microsoft is only now getting around it and it still pales in comparison to Valve's solution for Linux.
I’ve heard from several people who game on Windows that Gamescope side panel with OS-wide tweakables for overlays, performance, power, frame limiters and scaling is something that they miss after playing on Steam Deck. There are separate utilities for each, but not anything so simple and accessible as in Gamescope.
Valve... please do Github Actions next
I wonder what Valve uses for source control (no pun intended) internally.
Kernel level anti-cheat with trusted execution / signed kernels is probably a reasonable new frontier for online games, but it requires a certain level of adoption from game makers.
This is a part of Secure Boot, which Linux people have raged against for a long time. Mostly because the main key signing authority was Microsoft.
But here's my rub: no one else bothered to step up to be a key signer. Everyone has instead whined for 15 years and told people to disable Secure Boot and the loads of trusted compute tech that depends on it, instead of actually building and running the necessary infra for everyone to have a Secure Boot authority outside of big tech. Not even Red Hat/IBM even though they have the infra to do it.
Secure Boot and signed kernels are proven tech. But the Linux world absolutely needs to pull their heads out of their butts on this.
The goals of the people mandating Secure Boot are completely opposed to the goals of people who want to decide what software they run on the computer they own. Literally the entire point of remote attestation is to take that choice away from you (e.g. because they don't want you to choose to run cheating software). It's not a matter of "no one stepped up"; it's that Epic Games isn't going to trust my secure boot key for my kernel I built.
The only thing Secure Boot provides is the ability for someone else to measure what I'm running and therefore the ability to tell me what I can run on the device I own (mostly likely leading to them demanding I run malware like like the adware/spyware bundled into Windows). I don't have a maid to protect against; such attacks are a completely non-serious argument for most people.
And all this came from big game makers turning their games into casinos. The reason they want everything locked down is money is on the line.
anti-cheat far precedes the casinoification of modern games.
nobody wants to play games that are full of bots. cheaters will destroy your game and value proposition.
anti-cheat is essentially existential for studios/publishers that rely on multiplayer gaming.
So yes, the second half of your statement is true. The first half--not so much.
> anti-cheat far precedes the casinoification of modern games.
> nobody wants to play games that are full of bots. cheaters will destroy your game and value proposition.
You are correct, but I think I did a bad job of communicating what I meant. It's true that anti-cheat has been around since forever. However, what's changed relatively recently is anti-cheat integrated into the kernel alongside requirements for signed kernels and secure boot. This dates back to 2012, right as games like Battlefield started introducing gambling mechanics into their games.
There were certainly other games that had some gambly aspects to them, but 2010s is pretty close to where esports along with in game gambling was starting to bud.
There are plenty of locked down computers in my life already. I don't need or want another system that only runs crap signed by someone, and it doesn't really matter whether that someone is Microsoft or Redhat. A computer is truly "general purpose" only if it will run exactly the executable code I choose to place there, and Secure Boot is designed to prevent that.
I don't know overall in the ecosystem but Fedora has been working for me with secureboot enabled for a long time.
Having the option to disable secureboot, was probably due to backlash at the time and antitrust concerns.
Aside from providing protection "evil maid" attacks (right?) secureboot is in the interest of software companies. Just like platform "integrity" checks.
I'm pro secure boot fwiw and have had it working on my of my Linux systems for awhile.
I'm not giving game ownership of my kernel, that's fucking insane. That will lead to nothing but other companies using the same tech to enforce other things, like the software you can run on your own stuff.
No thanks.
Surely a gaming handheld counts
Imagine if windows moved to the linux kernel and then used wine/proton to serve their own userspace.
It kinda looked like this is the future, about at the same time they introduced WSL, released dotNET for Linux and started contributing to the Linux Kernel - all the while making the bank with Azure mostly thanks to running Linux workloads.
But then they deCided it is better to show adds at OS level, rewrite OS UI as a web app, force harware DRM for their new OS version (TPM requirement) as well as automatically capturing content of you screen and feed it to AI.
The Linux kernel and Windows userspace are not very well matched on a fundamental level. I’m not sure we should be looking forward to that, other than for running games and other insular apps.
Ah, I was being facetious, I think it would be pretty funny if it happened though.
Sounds like the sort of oddball corporate experiment that Action Retro or Michael MJD would be examining in fifteen years.
> I don't have an example in mind at the moment
I do, MIDI 2.0. It's not because they're not doing it, just that they're doing it at a glacial pace compared to everyone else. They have reasons for this (a complete rewrite of the windows media services APIs and internals) but it's taken years and delays to do something that shipped on Linux over two years ago and on Apple more like 5 (although there were some protocol changes over that time).
[deleted]
I do agree. It's also thanks to gaming that the GPU industry was in such a good state to be consumed by AI now. Game development used to always be the frontier of software optimisation techniques and ingenious approaches to the constraints.
I low key hope the current DDR5 prices push them to drag the Linux memory and swap management into the 21st century, too, because hard locking on low memory got old a while ago
It takes a solid 45 seconds for me to enable zram (compressed RAM as swap) on a fresh Arch install. I know that doesn't solve the issue for 99% of people who don't even know what zram is / have no idea how to do it / are trying to do it for the first time, but it would be pretty easy for someone to enable that in a distro. I wouldn't be shocked if it is already enabled by default in Ubuntu or Fedora.
Zram has been enabled on Fedora by default since 2020:
that just pushes away the problem ,it doesn't solve it. I still hit that limit when i ran a big compile while some other programs were using a lot of memory.
what behavior would you like to see when primary memory is under extreme pressure?
See mac or windows: grow swap automatically up to some sane limit, show a warning, give user an option to kill stuff; on headless systems, kill stuff. Do not page out critical system processes like sshd or the compositor.
A hard lock which requires a reboot or god forbid power cycling is the worst possible outcome, literally anything else which doesn’t start a fire is an improvement TBH.
> A hard lock which requires a reboot or god forbid power cycling is the worst possible outcome
Hilariously this happens on windows too.
Actually everything you said windows and mac doesn't do they do, if you put on a ton a memory pressure the system becomes unresponsive and locks up...
I've OOMd on my mac several times, and it has never gone completely unresponsive.
You get an OOM dialog with a list of apps that you can have it kill.
Same as Windows. Instead the system freezes.
I feel like all of the elements are there: zram, zswap, various packages that improve on default oom handling... maybe it's more about creating sane defaults that "just work" at this point?
I think it's more of a user space issue, that the UI doesn't degrade nicely. The kernel just defaults to a more server-oriented approach.
Next thing I want them to work on is Linux suspend(-to-RAM) support!
If anything it’s crazy that a company as large as meta is doing such a shitty job that it has to pull in solutions from entirely different industries … but that’s just my opinion
I have a feeling this will also drag Linux mobile forwards.
Currently almost no one is using Linux for mobile because the lack or apps (banking for example) and bad hardware support.
When developing for Linux becomes more and more attractive this might change.
> When developing for Linux becomes more and more attractive this might change.
If one (or maybe two) OSes win, then sure. The problem is there is no "develop for Linux" unless you are writing for the kernel.
Each distro is a standalone OS. It can have any variety of userland. You don't develop "for Linux" so much as you develop "for Ubuntu" or "for Fedora" or "for Android" etc.
If I'm not mistaken this has been greatly facilitated by the recent bpf based extension mechanism that allows developers to go crazy on creating schedulers and other functionality through some protected virtual machine mechanism provided by the kernel.
To be fair proton is based on DXVK which is some guy’s project because he wanted to play nier automata on Linux.
The guy is Philip Rebohler.
> Valve is practically singlehandedly dragging the Linux ecosystem forward in areas that nobody else wanted to touch.
I'm loving what valve has been doing, and their willingness to shove money into projects that have long been under invested in, BUT. Please don't forget all the volunteers that have developed these systems for years before valve decided to step up. All of this is only possible because a ton of different people spent decades slowly building a project, that for most of it's lifetime seemed like a dead end idea.
Wine as a software package is nothing short of miraculous. It has been monumentally expensive to build, but is provided to everyone to freely use as they wish.
Nobody, and I do mean NOBODY would have funded a project that spent 20 years struggling to run office and photoshop. Valve took it across the finish line into commercially useful project, but they could not have done that without the decade+ of work before that.
Long before Valve there was CrossOver which sold a polished version of Wine making a lot of Windows only enterprise software work on Linux.
I'm sure there have been more commercial contributors to Wine other than Valve and CodeWeavers.
Let's be honest
Linux (and its ecosystem) sucks at having focus and direction.
They might get something right here and there, especially related to servers, but they are awful at not spinning wheels
See how wayland progress is slow. See how some distros moved to it only after a lot of kicking and screaming.
See how a lot of peripherals in "newer" (sometimes a model that's 2 or 3 yrs on the market) only barely works in a newer distro. Or has weird bugs
"but the manufacturers..." "but the hw producers..." "but open source..." whine
Because Linux lacks a good hierarchy at isolating responsibility, otherwise going for a "every kernel driver can do all it wants" together with "interfaces that keep flipping and flopping at every new kernel release" - notable (good) exception : USB userspace drivers. And don't even get me started on the whole mess that is xorg drivers
And then you have a Ruby Goldberg machine in form of udev dbus and what not, or whatever newer solution that solves half the problems and create another new collection of bugs.
Honestly I can't see it remaining tenable to keep things like drivers in the kernel for too much longer… both due to the sheer speed at the industry moves and due to the security implications involved.
Man, if only meta would give back, oh and also stop letting scammers use their AI to scam our parents, but hey, that accounted for 10% of their revenue this last year, that's $16 BILLION.
Like them or not - when it comes to the Linux kernel they are one of the biggest contributors for many years now.

> This is the best kind of open source trickledown.
We shouldn't be depending on trickledown anything. It's nice to see Valve contributing back, but we all need to remember that they can totally evaporate/vanish behind proprietary licensing at any time.
They have to abide by the Wine license, which is basically GPL, so unless they’re going to make their own from scratch, they can’t make the bread and butter of their compat layer proprietary
That's why the anti-GPL push is so harmful. Specially in the Rust ecosystem
Can it vanish behind proprietary licensing? Pretty sure most of Valve’s stuff is under GPL so they can’t exactly evaporate that away.
How? It's GPL.
> SCX-LAVD has been worked on by Linux consulting firm Igalia under contract for Valve
It seems like every time I read about this kind of stuff, it's being done by contractors. I think Proton is similar. Of course that makes it no less awesome, but it makes me wonder about the contractor to employee ratio at Valve. Do they pretty much stick to Steam/game development and contract out most of the rest?
Igalia is a bit unique as it serves as a single corporate entity for organizing a lot of sponsored work on the Linux kernel and open source projects. You'll notice in their blog posts they have collaborations with a number of other large companies seeking to sponsor very specific development work. For example, Google works with them a lot. I think it really just simplifies a lot of logistics for paying folks to do this kind of work, plus the Igalia employees can get shared efficiency's and savings for things like benefits etc.
Oh ok, so Igalia owns the developer sweatshops now. Got it.
It's a cooperative sweatshop in that sense.
This isn’t explicitly called out in any of the other comments in my opinion so I’ll state this. Valve as a company is incredibly focused internally on its business. Its business is games, game hardware, and game delivery. For anything outside of that purview instead of trying to build a huge internal team they contract out. I’m genuinely curious why other companies don’t do this style more often because it seems incredibly cost effective. They hire top level contractors to do top tier work on hyper specific areas and everyone benefits. I think this kind of work is why Valve gets a free pass to do some real heinous shit (all the gambling stuff) and maintain incredible good will. They’re a true “take the good with the bad” kind of company. I certainly don’t condone all the bad they’ve put out, and I also have to recognize all the good they’ve done at the same time.
Back to the root point. Small company focused on core business competencies, extremely effective at contracting non-core business functions. I wish more businesses functioned this way.
Yeah, I suppose this workflow is not for everyone. I can only imagine Valve has very specific issue or requirements in mind when they hire contractors like this. When you hire like this, i suspect what one really pay for is a well known name that will be able to push something important to you to upstream linux. Its the right way to do it if you want it resolved quickly. If you come in as a fresh contributor, landing features upstream could take years.
Small company doesn't have the capital to contract out library work like that. Same story as it's always been
Whats the bad practices valve is doing in gambling?
Their games and systems tie into huge gambling operations on 3rd party sites
Yeah, im sorry. Valve is the last company people should be focusing for this type of behavior. All the other AAA game companies use these mechanics to deliberate manipulate players. IMHO valve doesn't use predatory practices to keep this stuff going.
How much of the video did you watch? I'm not aware of other game companies that enable 3rd party integrations into their item systems. This isn't just "lootboxes bad" - it's Valve profiting from actual gambling happening on external sites.
Just because they weren’t the first mover into predatory practices doesn’t mean they can’t say no to said practices. Each actor has agency to make their own operating and business decisions. Is Valve the worst of the lot? Absolutely not. But it was still their choice to implement.
What makes Valve special is that they were the first mover on those practices like lootboxes, gamepasses... but they never pushed it as far as the competition where it became predatory.
[deleted]
Loot box style underage gambling in their live service games - TF2 hats, counterstrike skins, "trading cards", etc etc
Lootboxes comes to mind.
I feel like I rarely see contacting out work go well. This seems like an exception
The .308 footgun with software contracting stems from a misunderstanding of what we pay software developers for. The model under which contracting seems like the right move is "we pay software developers because we want a unit of software", like how you pay a carpenter to build you some custom cabinets. If the union of "things you have a very particular opinion about, and can specify coherently" and "things you don't care about" completely cover a project, contracting works great for that purpose.
But most of the time you don't want "a unit of software", you want some amorphous blob of product and business wants and needs, continuously changing at the whims of business, businessmen, and customers. In this context, sure, you're paying your developers to solve problems, but moreover you're paying them to store the institutional knowledge of how your particular system is built. Code is much easier to write than to read, because writing code involves applying a mental model that fits your understanding of the world onto the application, whereas reading code requires you to try and recreate someone else's alien mental model. In the situation of in-house products and business automation, at some point your senior developers become more valuable for their understanding of your codebase than their code output productivity.
The context of "I want this particular thing fixed in a popular open source codebase that there are existing people with expertise in", contracting makes a ton of sense, because you aren't the sole buyer of that expertise.
If you have competent people on both sides who care, I don't see why it wouldn't work.
The problem seems, at least from a distance, to be that bosses treat it as a fire-and-forget solution.
We haven't had any software done by oursiders yet, but we have hired consultants to help us on specifics, like changing our infra and help move local servers to the cloud. They've been very effective and helped us a lot.
We had talks though so we found someone who we could trust had the knowledge, and we were knowledgeable enough ourselves that we could determine that. We then followed up closely.
Most companies that hiring a ton of contractors are doing it for business/financial reporting reasons. Contractors don't show up as employees so investors don't see employee count rise so metric of "Revenue/Employee" ratio does not get dragged down and contractors can be cut immediately with no further on expenses. Laid off employees take about quarter to be truly shed from the books between severance, vacation payouts and unemployment insurance.
I think your first 2 sentances are pretty common issues though.
Valve contracts out to actually competent people and companies rather than giant bodycount consulting firms.
Not to mention the code being open source & in need to be accepted upstream to be actually useful in the long term.
I've seen both good and bad contractors in multiple industries.
When I worked in the HFC/Fiber plant design industry, the simple act of "Don't use the same boilerplate MSA for every type of vendor" and being more specific about project requirements in the RFP makes it very clear what is expected, and suddenly we'd get better bids, and would carefully review the bids to make sure that the response indicated they understood the work.
We also had our own 'internal' cost estimates (i.e. if we had the in house capacity, how long would it take to do and how much would it cost) which made it clear when a vendor was in over their head under-bidding just to get the work, which was never a good thing.
And, I've seen that done in the software industry as well, and it worked.
That said, the main 'extra' challenge in IT is that key is that many of the good players aren't going to be the ones beating down your door like the big 4 or a WITCH consultancy will.
But really at the end of the day, the problem is what often happens is that business-people who don't really know (or necessarily -care-) about specifics enough unfortunately are the people picking things like vendors.
And worse, sometimes they're the ones writing the spec and not letting engineers review it. [0]
[0] - This once led to an off-shore body shop getting a requirement along the lines of 'the stored procedures and SQL called should be configurable' and sure enough the web.config had ALL the SQL and stored procedures as XML elements, loaded from config just before the DB call, thing was a bitch to debug and their testing alone wreaked havoc on our dev DB.
Igalia isn’t your typical contractor. It’s made up of competent developers that actually want to be there and care to see open source succeed. Completely different ball game.
Nope. Plenty of top-tier contractors work quietly with their clientele and let the companies take the credit (so long as they reference the contractor to others, keeping the gravy train going.)
If you don't see it happening, the game is being played as intended.
Valve is actually extremely small, I've heard estimates at around 350-400 people.
They're also a flat organization, with all the good and bad that brings, so scaling with contractors is easier than bringing on employees that might want to work on something else instead.
300 people isn’t “extremely small” for a company. I don’t work with/for companies over 100 people, for example, and those are already quite big.
Of course smaller companies exist — there are 1 person companies! But in a world where many tech companies have 50,000+ employees, 300 is much closer to 100 or 10 and they can all be considered small.
And then you consider it in context: a company with huge impact, brand recognition, and revenue (about $50M/employee in 2025). They’ve remained extremely small compared to how big they could grow.
I think a better way to think of it is in terms of revenue per employee. Valve is WAY up there.
the implied observation is that valve is extremely small relative to what it does and how big most people would expect it to be
Proton is mainly a co-effort between in-house developers at Valve (with support on specific parts from contractors like Igalia), developers at CodeWeavers and the wider community.
For contextual, super specific, super specialized work (e.g. SCX-LAVD, the DirectX-to-Vulkan and OpenGL-to-Vulkan translation layers in Proton, and most of the graphics driver work required to make games run on the upcoming ARM based Steam Frame) they like to subcontract work to orgs like Igalia but that's about it.
Valve is known to keep their employee count as low as possible. I would guess anything that can reasonably be contracted out is.
That said, something like this which is a fixed project, highly technical and requires a lot of domain expertise would make sense for _anybody_ to contract out.
They seem to be doing it through Igalia, which is a company based on specialized consulting for the Linux ecosystem, as opposed to hiring individual contractors. Your point still stands, but from my perspective this arrangement makes a lot of sense while the Igalia employees have better job security than they would as individual contractors.
This is how "Company funding OSS" looks like in real life.
There have been demands to do that more on HN lately. This is how it looks like when it happens - a company paying for OSS development.
It would be a large effort to stand up a department that solely focuses on Linux development just like it would be to shift game developers to writing Linux code. Much easier to just pay a company to do the hard stuff for you. I'm sure the steam deck hardware was the same, Valve did the overall design and requirements but another company did the actual hardware development.
Speaking for myself, Valve has been great to work with - chill, and they bring real technical focus. It's still engineers running the show there, and they're good at what they do. A real breath of fresh air from much of the tech world.
They probably needed some point expertise on this one, as they build out their teams.
I don't know what you're trying to suggest or question. If there is a question here, what is it exactly, and why is that question interesting? Do they employ contractors? Yes. Why was that a question?
Wut.
Valve has a weird obsession with maximizing their profit-per-employee ratio. There are stories from ex-employees out on the web about how this creates a hostile environment, and perverse incentives to sabotage those below you to protect your own job.
I don't remember all the details, but it doesn't seem like a great place to work, at least based on the horror stories I've read.
Valve does a lot of awesome things, but they also do a lot of shitty things, and I think their productivity is abysmal based on what you'd expect from a company with their market share. They have very successful products, but it's obvious that basically all of their income comes from rent-seeking from developers who want to (well, need to) publish on Steam.
There are numerous other ways to publish games. Is it really rent-seeking to own and maintain the most popular game publishing platform?
It's worth mentioning that sched_ext was developed at Meta. The schedulers are developed by several companies who collaborate to develop them, not just Meta or Valve or Italia and the development is done in a shared GitHub repo - https://github.com/sched-ext/scx.
That's the magic of open source. Valve can't say ohh noes you need a deluxe enterprise license.
In this case yes, but on the other hand Red Hat won't publish the RHEL code unless you have the binaries. The GPLv2 license requires you to provide the source code only if you provide the compiled binaries. In theory Meta can apply its own proprietary patches on Linux and don't publish the source code if it runs that patched Linux on its servers only.
RHEL source code is easily available to the public - via CentOS Stream.
For any individual RHEL package, you can find the source code with barely any effort. If you have a list of the exact versions of every package used in RHEL, you could compose it without that much effort by finding those packages in Stream. It's just not served up to you on a silver platter unless you're a paying customer. You have M package versions for N packages - all open source - and you have to figure out the correct construction for yourself.
Can't anyone get a RHEL instance on their favorite cloud, dnf install whatever packages they want sources of, email Redhat to demand the sources, and shut down the instance?
RHEL specifically makes it really annoying to see the source. You get a web view.
This violates the GPL, which explicitly states that recipients are entitled to the source tree in a form suitable for modification -- which a web view is not.
The source trees in a form suitable for modification (and pull requests) are here:
it's not the only way they offer the sauce through
Don't forget RH is owned by IBM.
Honestly just hearing this makes me want to get all their binaries, request the code, scrape it with OCR and upload it somewhere
But that would be silly, because all of the code and binaries is already available via CentOS Stream. There's nothing in RHEL that isn't already public at some point via CentOS Stream.
There's nothing special or proprietary about the RHEL code. Access to the code isn't an issue, it's reconstructing an exact replica of RHEL from all of the different package versions that are available to you, which is a huge temporal superset of what is specifically in RHEL.
I'm more surprised that the scheduler made for a handheld gaming console is also demonstrably good for Facebook's servers.
Latency-aware scheduling is important in a lot of domains. Getting video frames or controller input delivered on a deadline is a similar problem to getting voice or video packets delivered on a deadline. Meanwhile housecleaning processes like log rotation can sort of happen whenever.
Part of that is the assumption that Amazon/Meta/Google all have dedicated engineers who should be doing nothing but tuning performance for 0.0001% efficiency gains. At the scale of millions of servers, those tweaks add up to real dollar savings, and I suspect little of how they run is stock.
This is really just an example of survivorship bias and the power of Valve's good brand value. Big tech does in fact employ plenty of people working on the kernel to make 0.1% efficiency gains (for the reason you state), it's just not posted on HN. Someone would have found this eventually if not Valve.
And the people at FB who worked to integrate Valve's work into the backend and test it and measure the gains are the same people who go looking for these kernel perf improvements all day.
CFS was replaced by EEVDF, no?
I vaguely remember reading when this occurred. It was very recent no? Last few years for sure.
> The Linux kernel began transitioning to EEVDF in version 6.6 (as a new option in 2024), moving away from the earlier Completely Fair Scheduler (CFS) in favor of a version of EEVDF proposed by Peter Zijlstra in 2023 [2-4]. More information regarding CFS can be found in CFS Scheduler.
Ultimately, CPU schedulers are about choosing which attributes to weigh more heavily. See this[0] diagram from Github. EEVDF isn't a straight upgrade on CFS. Nor is LAVD over either.
Just traditionally, Linux schedulers have been rather esoteric to tune and by default they've been optimized for throughput and fairness over everything else. Good for workstations and servers, bad for everyone else.
> Starting from version 6.6 of the Linux kernel, [CFS] was replaced by the EEVDF scheduler.[citation needed]
I mean.. many SteamOS flavors (and Linux distros in general have) have switched to Meta's Kyber IO scheduler to fix microstutter issues.. the knife cuts both ways :)
Kyber is an I/O scheduler. Nothing to do with this article.
The comment was perfectly valid and topical and applicable. It doesn't matter what kind of improvement Meta supplied that everyone else took up. It could have been better cache invalidation or better usb mouse support.
Well if you think about it, in this case the license is the 30% cut on every game you purchase on steam.
I've been using Bazzite Desktop for 4 months now and it has been my everything. Windows is just abandonware now even with every update they push. It is clunky and hard to manage.
Isn't bazzite a gaming focused distribution ? It seems weird to install it on a PC that does 'my everything'.
I wouldn't make excel spreadsheet on the steam deck for instance.
Bazzite is advertised for gamers, however from my understanding it's just Fedora Atomic wrapped up to work well on steamdeck adjacent hardware and gaming is a top priority. You'd still be receiving the same level of quality you would expect from Fedora/RHEL (I would think).
Why not? It has full desktop mode with Plasma and can be docked like PC
I'm curious how this came to be:
> Meta has found that the scheduler can actually adapt and work very well on the hyperscaler's large servers.
I'm not at all in the know about this, so it would not even occur to me to test it. Is it the case that if you're optimizing Linux performance you'd just try whatever is available?
almost certainly bottom-up: some eng somewhere read about it, ran a test, saw positive results, and it bubbles up from there. this is still how lots of cool things happen at big companies like Meta.

I'm struggling to understand what workloads Meta might be running that are _this_ latency-critical.
According to the video linked somewhere in this thread indicates WhatsApp Erlang workers that want sub-ms latency.
It's definitely for ads auctions
Meta is a humongous company. Any kind of latency has to have a business impact.
It's Meta. They always push to be that fast on paper, even when it's costly to do and doesn't really need it.
If you have 50,000 servers for your service, and you can reduce that by 1 percent, you save 50 servers. Multiply that by maybe $8k per server and you have saved $400k,you just paid for your self for a year. With meta the numbers are probably a bit bigger.
LOL (I used to work for Meta, so appreciate the facetious understatement)
That's not how it works though. Budgets are annual. A 1% savings of cpu cycles doesn't show up anywhere, it's a rounding error. They don't have a guy that pulls the servers and sells them ahead of the projection. You bought them for 5 years and they're staying. 5 years from now, that 1% got eaten up by other shit.
You're wrong about how services that cost 9+ figures to run annually are budgeted. 1% CPU is absolutely massive and well measured and accounted for in these systems.
You don't buy servers once every 5 years. I've done purchasing every quarter and forecasted a year out. You reduce your services budget for hardware by the amount saved for that year.
Interesting to see server workloads take ideas from other areas. I saw recently that some of the k8s specific os do their updates like android devices
You mean immutable?
That wasn't what I was thinking about. There's a phrase for it using active and back up partitions but I can't find what it's called
A/B updates?

Posting an AI summary is about as useful as posting Google search results. We can all do it, we don't need anyone to do it for us.
As well as the points already raised by others, I'd like to make the point that we should be encouraging people to prompt LLMs themselves rather than just accepting the outputs of others. As a social norm, this will make society more robust to misinformation and deception, as it will result in fewer people trusting outputs without knowing how the LLM was actually prompted.
This probably doesn't really matter in this context, but I think it's a general best practice worth reinforcing whenever possible.
If someone want to ask an LLM about something, good for them, but there's no need to paste its content over the internet, disclosed or not.
Valve is practically singlehandedly dragging the Linux ecosystem forward in areas that nobody else wanted to touch.
They needed Windows games to run on Linux so we got massive Proton/Wine advancements. They needed better display output for the deck and we got HDR and VRR support in wayland. They also needed smoother frame pacing and we got a scheduler that Zuck is now using to run data centers.
Its funny to think that Meta's server efficiency is being improved because Valve paid Igalia to make Elden Ring stutter less on a portable Linux PC. This is the best kind of open source trickledown.
One would've expected one of the many desktop-oriented distros (some with considerable funding, even) to have tackled these things already, but somehow desktop Linux has been stuck in the awkward midway of "it technically works, just learn to live with the rough edges" until finally Valve took initiative. Go figure.
That isn't it. Generally whatever the majority of users tend to use that where the majority of focus goes.
The vast majority of people that were using Linux on the desktop were either hobbyists, developers or people that didn't want to run proprietary software for whatever reason. These people generally didn't care about HDR, VRR, Wayland and all the other gumpf mentioned. So this stuff didn't get fixed.
Please don't erase all the groundwork they've done over the years to make it possible for these later enhancements to happen. It wasn't like they were twiddling their thumbs this whole time!
That's not my intention at all. It's just frustrating how little of it translates to impact that's readily felt by end users, including those of us without technical inclination.
There's far more of that, starting with the lack of a stable ABI in gnu/linux distros. Eventually Valve or Google (with Android) are gonna swoop in with a user-friendly, targetable by devs OS that's actually a single platform
I don't have a whole lot of faith in Google, based on considerable experience with developing for Android. Put plainly, it's a mess, and even with improvements in recent years there's enough low-hanging fruit for improving its developer story that much of it has fallen off the tree and stands a foot thick on the ground.
The enterprise distros do provide that, somewhat.
That's why, RHEL for example, has such a long support lifecycle. It's so you can develop software targeting RHEL specifically, and know you have a stable environment for 10+ years. RHEL sells a stable (as in unchanging) OS for x number of years to target.
And if you want to follow the RHEL shaped bleeding edge you can develop on latest Fedora. I'll often do this, develop/package and Fedora and then build on RHEL as well.
Ubuntu LTS is currently on track to be that. Both in the server and desktop space, in my personal experience it feels like a rising number of commercial apps are targeting that distro specifically.
It’s not my distribution of choice, but it’s currently doing exactly what you suggest.
I just installed Ubuntu again after a few years, and it’s striking how familiar the pain points are—especially around graphics. If Ubuntu LTS is positioning itself as the standard commercial Linux target, it has to clearly outperform Windows on fundamentals, not just ideology. Linux feels perpetually one breakthrough release away from actually displacing it.
The problem with any LTS release is lack of support for newer hardware. Not as much of an issue for an enthusiast or sysadmin who's likely to be using well-supported hardware, but can be a huge one for a more typical end user hoping to run Linux on their recently purchased laptop.
Is that true? I did just that on my newly purchsed laptop in 2023. It was a thinkpad though.
Isn't that the steam linux runtime? Games linked against the runtime many years ago still run on modern distros.
Over time they're going to touch things that people were waiting for Microsoft to do for years. I don't have an example in mind at the moment, but it's a lot better to make the changes yourself than wait for OS or console manufacturer to take action.
I was at Microsoft during the Windows 8 cycle. I remember hearing about a kernel feature I found interesting. Then I found linux had it for a few years at the time.
I think the reality is that Linux is ahead on a lot of kernel stuff. More experimentation is happening.
I was surprised to hear that Windows just added native NVMe which Linux has had for many years. I wonder if Azure has been paying the SCSI emulation tax this whole time.
Probably, most of stuff you see in Windows Server these days is backported from Azure improvements.
Afaik Azure is mostly Linux
The user VMs are mostly Linux but Azure itself runs on a stripped down version of Windows Server and all the VMs are hosted inside Hyper-V. See https://techcommunity.microsoft.com/blog/windowsosplatform/a...
It was always wild to me that their installer was just not able to detect an NVMe drive out of the box in certain situations. I saw it a few times with customers when I was doing support for a Linux company.

Passion over paycheques
yeah, but you have IO Completion Ports…
IO_Uring is still a pale imitation :(
If that were true then presumably Microsoft wouldn't have ported it to Windows:
https://learn.microsoft.com/en-us/windows/win32/api/ioringap...
Although Windows registered network I/O (RIO) came before io_uring and for all I know might have been an inspiration:
https://learn.microsoft.com/en-us/previous-versions/windows/...
That argument holds no water. IOUring is essential for the performance of some modern POSIX programs.
You can see shims for fork() to stop tanking performance so hard too. IOUring doesnt map at all onto IOCP, at least the windows subtitute for fork has “ZwCreateProcess“ to work from. IOUring had nothing.
IOCP is much nicer from a dev point of view because your program can be signalled when a buffer has data on it but also with the information of how much data, everything else seems to fail at doing this properly.
The CQE for e.g. a successful read(2) operation will have the number of bytes read in the `res` field.
io_uring does more than IOCP. It's more like an asynchronous syscall interface that avoids the overhead of directly trapping into the kernel. This avoids some overheads IOCP cannot. I'm rusty on the details but the NT kernel has since introduced an imitation: https://learn.microsoft.com/en-us/windows/win32/api/ioringap...
IOCP is great and was ahead of Linux for decades, but io_uring is also great. It's a different model, not a poor copy.
I think they are a bit different - in the Windows kernel, all IO is asynchronous on the driver level, on Linux, it's not.
io_uring didn't change that, it only got rid of the syscall overhead (which is still present on Windows), so in actuality they are two different technical solutions that affect different levels of the stack.
In practice, Linux I/O is much faster, owing in part to the fact that Windows file I/O requires locking the file, while Linux does not.
io_uring makes synchronous syscalls async simply by offloading them to a pool of kernel threads, just like people have done for decades in userspace.
Yeah and Linux is waaay behind in other areas. Windows had a secure attention sequence (ctrl-alt-del to login) for several decades now. Linux still doesn't.
Linux (well, more accurately, X11), has had a SAK for ages now, in the form of the CTRL+ALT+BACKSPACE that immediately kills X11, booting you back to the login screen.
I personally doubt SAK/SAS is a good security measure anyways. If you've got untrusted programs running on your machine, you're probably already pwn'd.
The "threat model" (if anyone even called it that) of applications back then was bugs resulting in unintended spin-locks, and the user not realizing they're critically short on RAM or disk space.
This setup came from the era of Windows running basically everything as administrator or something close to it.
The whole windows ecosystem had us trained to right click on any Windows 9X/XP program that wasn’t working right and “run as administrator” to get it to work in Vista/7.
Well, there is: https://en.wikipedia.org/wiki/Magic_SysRq_key
That's not the same thing at all.
Is that something Linux needs? I don’t really understand the benefit of it.
The more powerful form is the UAC full privilege escalation dance that Win 7+(?) does, which is a surprisingly elegant UX solution.
It avoids any chance of a user-space program faking or interacting with a UAC window.Clever way of dealing with the train wreck of legacy Windows user/program permissioning.
My only experience with non-UAC endpoint privilege management was BeyondTrust and it seemed to try to do what UAC did but with a worse user experience. It looks like the Intune EPM offering also doesn't present as clear a delineation as UAC, which seems like a missed opportunity.
>Display the snapshot in the background, greyed out,
Is there an offset. I could have sworn things always seemed offset to the side a little.
One of the things Windows did right, IMO. I hate that elevation prompts on macOS and most linux desktops are indistinguishable from any other window.
It's not just visual either. The secure desktop is in protected memory, and no other process can access it. Only NTAUTHORITY\System can initiate showing it and interact with it any way, no other process can.
You can also configure it to require you to press CTRL+ALT+DEL on the UAC prompt to be able to interact with it and enter credentials as another safeguard against spoofing.
I'm not even sure if Wayland supports doing something like that.
It made a lot more sense in the bygone years of users casually downloading and running exe's to get more AIM "smilies", or putting in a floppy disk or CD and having the system autoexec whatever malware the last user of that disk had. It was the expected norm for everybody's computer to be an absolute mess.
These days, things have gotten far more reasonable, and I think we can generally expect a linux desktop user to only run software from trusted sources. In this context, such a feature makes much less sense.
It's useful for shared spaces like schools, universities and internet cafes. The point is that without it you can display a fake login screen and gather people's passwords.
I actually wrote a fake version of RMNet login when I was in school (before Windows added ctrl-alt-del to login).
https://www.rmusergroup.net/rm-networks/
I got the teacher's password and then got scared and deleted all trace of it.

And behind on a lot of stuff. The Microsoft's ACLs are nothing short of one of the best designed permission systems there are.
On the surface, they are as simple as Linux UOG/rwx stuff if you want it to be, but you can really, REALLY dive into the technology and apply super specific permissions.
> The Microsoft's ACLs are nothing short of one of the best designed permission systems there are.
You have a hardened Windows 11 system. A critical application was brought forward from a Windows 10 box but it failed, probably a permissions issue somewhere. Debug it and get it working. You can not try to pass this off to the vendor, it is on you to fix it. Go.
and why is it not on the vendor of the critical application?
Because they aren't allowed on the system where it is installed, and also they don't deal with hardened systems.
Procmon.exe. Give me 2 minutes. You make it sound like it's such a difficult thing to do. It literally will not take me more than 2 minutes to tell you exactly where the permission issue is and how to fix it.
Procmon won't show you every type of resource access. Even when it does, it won't tell you which entity in the resource chain caused the issue.
And then you get security product who have the fun idea of removing privileges when a program creates a handle (I'm not joking, that's a thing some products do). So when you open a file with write access, and then try to write to the file, you end up with permission errors durig the write (and not the open) and end up debugging for hours on end only to discover that some shitty security product is doing stupid stuff...
Granted, thats not related to ACLs. But for every OK idea microsoft had, they have dozen of terrible ideas that make the whole system horrible.
Especially when the permission issue is up the chain from the application. Sure it is allowed to access that subkey, but not the great great grandparent key.
And they work on everything. You can have a mutex, a window handle or a process protected by ACL.
The file permission system on Windows allows for super granular permissions, yes; administrating those permissions was a massive pain, especially on Windows file servers.
Do you have any favorite docs or blogs on these? Reading about one of the best designed permissions systems sounds like a fun way to spend an afternoon ;)
You have ACLs on linux too
ACLs in Linux were tacked on later; not everything supports them properly. They were built into Windows NT from the start and are used consistently across kernel and userspace, making them far more useful in practice.
Also, as far as I know Linux doesn't support DENY ACLs, which Windows does.
Yes it does.
since when?
Since some of us could be bothered reading docs. Give it a try and see how it works out for you.
Some of us can! I certainly enjoy doing it, and according to "man 5 acl" what you assert is completely false. Unless you have a particular commit or document from kernel.org you had in mind?
> Each of these characters is replaced by the - character to denote that a permission is absent in the ACL entry.
Wouldn't the o::--- default ACL, like mode o-rwx, deny others access in the way you're describing?
Haha, sure. Sorry, it's not you, it's the ACLs (and me nerves). Have you tried configuring NFSv4 ACLs on Linux? Because kernel devs are against supporting them, you either use some other OS or have all sorts of "fun". Also, not to be confused with all sorts of LSM based ACLs... Linux has ACLs in the most ridiculous way imaginable...
Not by default. Not as extensive as in Windows. What's your point?
Oh yeah for sure. Linux is amazing in a computer science sense, but it still can't beat Windows' vertically integrated registry/GPO based permissions system. Group/Local Policy especially, since it's effectively a zero coding required system.
Ubuntu just recently got a way to automate its installer (recently being during covid). I think you can do the same on RHEL too. But that's largely it on Linux right now. If you need to admin 10,000+ computers, Windows is still the king.
Debian (and thus Ubuntu) has full support for automated installs since the 90's. It's built into `dpkg` since forever. That include saving or generating answer to install time questions, PXE deployment, ghosting, CloudInit and everything. Then stuff like Ansible/Puppet have been automating deployment for a long time too. They might have added yet another way of doing it, but full stack deployment automation has been there for as long as Ubuntu existed.
> Ubuntu just recently got a way to automate its installer (recently being during covid).
Preseed is not new at all:
https://wiki.debian.org/DebianInstaller/Preseed
RH has also had kickstart since basically forever now.
I've been using both preseeds and kickstart professionally for over a decade. Maybe you're thinking of the graphical installer?
> Ubuntu just recently got a way to automate its installer (recently being during covid). I think you can do the same on RHEL too. But that's largely it on Linux right now. If you need to admin 10,000+ computers, Windows is still the king.
What?! I was doing kickstart on Red Hat (want called Enterprise Linux back then) at my job 25 years ago, I believe we were using floppies for that.
Yeah, I have been working on the RHEL and Fedora installer since 2013 and already back then it had a long history almost lost to time - the git history goes all the way back to 1999 (the history was imported from CVS, as it predates Git) and that actually only cover the first graphical interface - it had automated installation support via kickstart and a text interface long before that, but the commit history has been apparently lost. And there seems to have been even some earlier distict installer before Anaconda, that likely also supported some sort of automated install.
BTW, we managed to get the earlies history of the project written down here by one of the earliest contributors for anyone who might be interested:
https://anaconda-installer.readthedocs.io/en/latest/intro.ht...
As for how the automated installation on RHEL, Fedora and related distros works - it is indeed via kickstart:
https://pykickstart.readthedocs.io/en/latest/
Note how some commands were introduced way back in the single digit Fedora/Fedora Core age - that was from about 2003 to 2008. Latest Fedora is Fedora 43. :)
Still the king but developing/testing/debugging group policy issues is a miserable experience.
I always found it straight forward. Never had an issue and I've implemented my fair share on thousands on devices and servers.
Not an implementer of group policy, more of a consumer. There are 2 things that I find extremely problematic about them in practice.
- There does not seem to be a way to determine which machines in the fleet have successfully applied. If you need a policy to be active before doing deployment of something (via a different method), or things break, what do you do?
- I’ve had far too many major incidents that were the result of unexpected interactions between group policy and production deployments.
> Ubuntu just recently got a way to automate its installer (recently being during covid). I think you can do the same on RHEL too. But that's largely it on Linux right now. If you need to admin 10,000+ computers, Windows is still the king.
1. cloud-init support was in RHEL 7.2 which released November 19, 2015. A decade ago.
2. Checking on Ubuntu, it looks like it was supported in Ubuntu 18.04 LTS in April 2018.
3. For admining tens of thousands of servers, if you're in the RHEL ecosystem you use Satellite and it's ansible integration. That's also been going on for... about a decade. You don't need much integration though other than a host list of names and IPs.
There are a lot of people on this list handling tens of thousands or hundreds of thousands of linux servers a day (probably a few in the millions).
I'm surprised no one has said NixOS yet.
Tbh i'm starting to think that I do not see microsoft being able to keep it's position in the OS market ; with steam doing all the hard work and having a great market to play with ; the vast distributions to choose from, and most importantly how easy it has become to create an operating system from scratch - they not only lost all possible appeal, they seem stuck on really weird fetichism with their taskbar and just didn't provide me any kind of reason to be excited about windows.
Their research department rocks however so it's not a full bash on Microsoft at all - i just feel like they are focusing on other way more interesting stuff
> Tbh i'm starting to think that I do not see microsoft being able to keep it's position in the OS market
It's a big space. Traditionally, Microsoft has held both the multimedia, gaming and lots of professional segments, but with Valve doing a large push into the two first and Microsoft not even giving it a half-hearted try, it might just be that corporate computers continue using Microsoft, people's home media equipment is all Valve and hipsters (and others...) keep on using Apple.
I think that's the most likely way it'll go.
Windows will remain as the default "enterprise desktop." It'll effectively become just another piece of business software, like an ERP.
Gamers, devs, enthusiasts will end up on Linux and/or SteamOS via Valve hardware, creatives and personal users that still use a computer instead of their phone or tablet will land in Apple land.
With the massive adoption of web apps in Enterprise I have seen I would expect Windows to become irelevant or even a liability in business use as well.
Kernel improvements are interesting to geeks and data centers, but open source is fundamentally incompatible with great user experience.
Great UX requires a lot of work that is hard but not algorithmically challenging. It requires consistency and getting many stakeholders to buy in. It requires spending lots of time on things that will never be used by more than 10-20% of people.
Windows got a proper graphics compositor (DWM) in 2006 and made it mandatory in 2012. macOS had one even earlier. Linux fought against Compiz and while Wayland feels inevitable vocal forces still complain about/argue against it. Linux has a dozen incompatible UI toolkits.
Screen readers on Linux are a mess. High contrast is a mess. Setting font size in a way that most programs respect is a mess. Consistent keyboard shortcuts are a mess.
I could go on, but these are problems that open source is not set up to solve. These are problems that are hard, annoying, not particularly fun. People generally only solve them when they are paid to, and often only when governments or large customers pass laws requiring the work to be done and threaten to not buy your product if you don't do it. But they are crucially important things to building a great, widely adopted experience.
…and you are implying that Microsoft Windows 11 is a better example of ”great user experience”?
If you have anything less than perfect vision and need any accessibility features, yes. If you have a High DPI screen, yes. In many important areas (window management, keyboard shortcuts, etc.), yes.
Here's one top search result that goes into far more detail: https://www.reddit.com/r/linux/comments/1ed0j10/the_state_of...
For the general user, yes absolutely.
Linux DEs still can't match the accessibility features alone.
yeah, there's layers and layers of progressively older UIs layered around the OS, but most of it makes sense, is laid out sanely, and is relatively consistent with other dialogs.
macOS beats it, but its still better in a lot of ways over the big Linux DEs.
Start menu in the middle of the screen that takes a couple seconds to even load (because it is implemented in React horribly enought to be this slow) only to show adds next to everything is perfect user experience.
Every other button triggering Copilots assures even better UX goodness.
Add to that all the bullshit they have been pushing on their customers lately: * OS level adds
* invasive AI integration
* dropping support for 40% of their installed base (Windows 10)
* forcing useless DRM/trusted computing hardware - TPM - as a requirement to install the new and objectively worse Windows version version, with even more spying and worse performance (Windows 11)
With that I think their prospects are bleak & I have no idea who would install anything else than Steam OS or Bazzite in the future with this kind of Microsoft behavior.
"It just works" sleep and hibernate.
"Slide left or right" CPU and GPU underclocking.
“it just works” sleep was working, at least on basically every laptop I had the last 10 years…
until the new s2idle stuff that Microsoft and Intel have foisted on the world (to update your laptop while sleeping… I guess?)
From what I read, it was a lot of the prosumer/gamer brands (MSI, Gigabyte, ASUS) implementing their part of sleep/hibernate badly on their motherboards. Which honestly lines up with my experience with them and other chips they use (in my case, USB controllers). Lots of RGB and maybe overclocking tech, but the cheapest power management and connectivity chips they can get (arguably what usually gets used the most by people).
Sleep brokenness is ecosystem-wide. My Thinkpad crashes/freezes during sleep 3 times a week. Lenovo serviced/replaced it 3 times to no avail.
It never really worked in games even with S3 sleep. The new connected standby stuff created new issues but sleeping a laptop while gaming was a roulette wheel. SteamOS and the like actually work, like maybe 1/100 times I've run into an issue. Windows was 50/50.
Sleep and hibernate don't just work on Windows unless Microsoft work with laptop and boards manufacturers to make Windows play nice with all those drivers. It's inevitable that it's hit and miss on any other OS that manufacturers don't care much about. Apple does nearly everything inside their walls, that's why it just works.
“It just works” sadly isn’t true across the Apple Ecosystem anymore.
Liquid Glass ruined multitasking UX on my iPad. :(
Also my macbook (m4 pro) has random freezes where finder becomes entirely unresponsive. Not sure yet why this happens but thankfully it’s pretty rare.
Regardless of how it must be implemented, if this is a desirable feature then this explanation isn’t an absolution of Linux but rather an indictment: its development model cannot consistently provide this product feature.
(And same for Windows to the degree it is more inconsistent on Windows than Mac)
> its development model cannot consistently provide this product feature.
The real problem is that the hardware vendors aren't using its development model. To make this work you either need a) the hardware vendor to write good drivers/firmware, or b) the hardware vendor to publish the source code or sufficient documentation so that someone else can reasonably fix their bugs.
The Linux model is the second one. Which isn't what's happening when a hardware vendor doesn't do either of them. But some of them are better than others, and it's the sort of thing you can look up before you buy something, so this is a situation where you can vote with your wallet.
A lot of this is also the direct fault of Microsoft for pressuring hardware vendors to support "Modern Standby" instead of rather than in addition to S3 suspend, presumably because they're organizationally incapable of making Windows Update work efficiently so they need Modern Standby to paper over it by having it run when the laptop is "asleep" and then they can't have people noticing that S3 is more efficient. But Microsoft's current mission to get everyone to switch to Linux appears to be in full swing now, so we'll see if their efforts on that front manage to improve the situation over time.
The feature itself works. There are just hardware that is buggy and don't support it properly.
That's a vastly different statement.
It's not the development model at fault here. It's the simple fact that Windows makes up nearly the entire user base for PCs. Companies make sure their hardware works with Windows, but many don't bother with Linux because it's such a tiny percentage of their sales.
Except when it doesn't. I can't upgrade my Intel graphics drivers to any newer version than what came with the laptop or else my laptop will silently die while asleep. Internet is full of similar reports from other laptop and graphics manufacturers and none have any solutions that work. The only thing that reliably worked is to restore the original driver version. Doesn't matter if I use the WHQL version(s) or something else.
> Regardless of how it must be implemented, if this is a desirable feature then this explanation isn’t an absolution of Linux but rather an indictment: its development model cannot consistently provide this product feature.
The problem is: the specifications of ACPI are complex, Windows' behavior tends to be pretty much trash and most hardware tends to be trash too (AMD GPUs for example were infamous for not being resettable for years [1]), which means that BIOSes have to work around quirks on both the hardware and software. Usually, as soon as it is reasonably working with Windows (for a varying definition of "reasonably", that is), the ACPI code is shipped and that's it.
Unfortunately, Linux follows standards (or at least, it tries to) and cannot fully emulate the numerous Windows quirks... and on top of that, GPUs tend to be hot piles of dung requiring proprietary blobs that make life even worse.

On my Framework 13 AMD : Sleep just works on Fedora. Sleep is unreliable on Windows; if my fans are all running at full speed while running a game and I close the lid to begin sleeping, it will start sleeping and eventually wake up with all fans blaring.
I don't understand this comment in this context. Both of these features work on my Steam Deck. Neither of them have worked on any Windows laptop my employers have foisted upon me.
That requires driver support. What you're seeing is Microsoft's hardware certification forcing device vendors to care about their products. You're right that this is lacking on Linux, but it's not a slight on the kernel itself.
Both of these have worked fine for the last 15 years or so on all my laptops.
A good one is the shader pre caching with fossilize, microsoft is only now getting around it and it still pales in comparison to Valve's solution for Linux.
I’ve heard from several people who game on Windows that Gamescope side panel with OS-wide tweakables for overlays, performance, power, frame limiters and scaling is something that they miss after playing on Steam Deck. There are separate utilities for each, but not anything so simple and accessible as in Gamescope.
Valve... please do Github Actions next
I wonder what Valve uses for source control (no pun intended) internally.
They use Perforce.

Kernel level anti-cheat with trusted execution / signed kernels is probably a reasonable new frontier for online games, but it requires a certain level of adoption from game makers.
This is a part of Secure Boot, which Linux people have raged against for a long time. Mostly because the main key signing authority was Microsoft.
But here's my rub: no one else bothered to step up to be a key signer. Everyone has instead whined for 15 years and told people to disable Secure Boot and the loads of trusted compute tech that depends on it, instead of actually building and running the necessary infra for everyone to have a Secure Boot authority outside of big tech. Not even Red Hat/IBM even though they have the infra to do it.
Secure Boot and signed kernels are proven tech. But the Linux world absolutely needs to pull their heads out of their butts on this.
The goals of the people mandating Secure Boot are completely opposed to the goals of people who want to decide what software they run on the computer they own. Literally the entire point of remote attestation is to take that choice away from you (e.g. because they don't want you to choose to run cheating software). It's not a matter of "no one stepped up"; it's that Epic Games isn't going to trust my secure boot key for my kernel I built.
The only thing Secure Boot provides is the ability for someone else to measure what I'm running and therefore the ability to tell me what I can run on the device I own (mostly likely leading to them demanding I run malware like like the adware/spyware bundled into Windows). I don't have a maid to protect against; such attacks are a completely non-serious argument for most people.
And all this came from big game makers turning their games into casinos. The reason they want everything locked down is money is on the line.
anti-cheat far precedes the casinoification of modern games.
nobody wants to play games that are full of bots. cheaters will destroy your game and value proposition.
anti-cheat is essentially existential for studios/publishers that rely on multiplayer gaming.
So yes, the second half of your statement is true. The first half--not so much.
> anti-cheat far precedes the casinoification of modern games.
> nobody wants to play games that are full of bots. cheaters will destroy your game and value proposition.
You are correct, but I think I did a bad job of communicating what I meant. It's true that anti-cheat has been around since forever. However, what's changed relatively recently is anti-cheat integrated into the kernel alongside requirements for signed kernels and secure boot. This dates back to 2012, right as games like Battlefield started introducing gambling mechanics into their games.
There were certainly other games that had some gambly aspects to them, but 2010s is pretty close to where esports along with in game gambling was starting to bud.
There are plenty of locked down computers in my life already. I don't need or want another system that only runs crap signed by someone, and it doesn't really matter whether that someone is Microsoft or Redhat. A computer is truly "general purpose" only if it will run exactly the executable code I choose to place there, and Secure Boot is designed to prevent that.
I don't know overall in the ecosystem but Fedora has been working for me with secureboot enabled for a long time.
Having the option to disable secureboot, was probably due to backlash at the time and antitrust concerns.
Aside from providing protection "evil maid" attacks (right?) secureboot is in the interest of software companies. Just like platform "integrity" checks.
I'm pro secure boot fwiw and have had it working on my of my Linux systems for awhile.
I'm not giving game ownership of my kernel, that's fucking insane. That will lead to nothing but other companies using the same tech to enforce other things, like the software you can run on your own stuff.
No thanks.
Surely a gaming handheld counts
Imagine if windows moved to the linux kernel and then used wine/proton to serve their own userspace.
It kinda looked like this is the future, about at the same time they introduced WSL, released dotNET for Linux and started contributing to the Linux Kernel - all the while making the bank with Azure mostly thanks to running Linux workloads.
But then they deCided it is better to show adds at OS level, rewrite OS UI as a web app, force harware DRM for their new OS version (TPM requirement) as well as automatically capturing content of you screen and feed it to AI.
The Linux kernel and Windows userspace are not very well matched on a fundamental level. I’m not sure we should be looking forward to that, other than for running games and other insular apps.
Ah, I was being facetious, I think it would be pretty funny if it happened though.
Sounds like the sort of oddball corporate experiment that Action Retro or Michael MJD would be examining in fifteen years.
> I don't have an example in mind at the moment
I do, MIDI 2.0. It's not because they're not doing it, just that they're doing it at a glacial pace compared to everyone else. They have reasons for this (a complete rewrite of the windows media services APIs and internals) but it's taken years and delays to do something that shipped on Linux over two years ago and on Apple more like 5 (although there were some protocol changes over that time).
I do agree. It's also thanks to gaming that the GPU industry was in such a good state to be consumed by AI now. Game development used to always be the frontier of software optimisation techniques and ingenious approaches to the constraints.
I low key hope the current DDR5 prices push them to drag the Linux memory and swap management into the 21st century, too, because hard locking on low memory got old a while ago
It takes a solid 45 seconds for me to enable zram (compressed RAM as swap) on a fresh Arch install. I know that doesn't solve the issue for 99% of people who don't even know what zram is / have no idea how to do it / are trying to do it for the first time, but it would be pretty easy for someone to enable that in a distro. I wouldn't be shocked if it is already enabled by default in Ubuntu or Fedora.
Zram has been enabled on Fedora by default since 2020:
https://fedoraproject.org/wiki/Changes/SwapOnZRAM
that just pushes away the problem ,it doesn't solve it. I still hit that limit when i ran a big compile while some other programs were using a lot of memory.
what behavior would you like to see when primary memory is under extreme pressure?
See mac or windows: grow swap automatically up to some sane limit, show a warning, give user an option to kill stuff; on headless systems, kill stuff. Do not page out critical system processes like sshd or the compositor.
A hard lock which requires a reboot or god forbid power cycling is the worst possible outcome, literally anything else which doesn’t start a fire is an improvement TBH.
> A hard lock which requires a reboot or god forbid power cycling is the worst possible outcome
Hilariously this happens on windows too.
Actually everything you said windows and mac doesn't do they do, if you put on a ton a memory pressure the system becomes unresponsive and locks up...
I've OOMd on my mac several times, and it has never gone completely unresponsive.
You get an OOM dialog with a list of apps that you can have it kill.
Same as Windows. Instead the system freezes.
I feel like all of the elements are there: zram, zswap, various packages that improve on default oom handling... maybe it's more about creating sane defaults that "just work" at this point?
I think it's more of a user space issue, that the UI doesn't degrade nicely. The kernel just defaults to a more server-oriented approach.
Next thing I want them to work on is Linux suspend(-to-RAM) support!
Gaben is our lord and saviour.
My favourite is the Windows futex primitives being shipped on Linux: https://lwn.net/Articles/961884/
If anything it’s crazy that a company as large as meta is doing such a shitty job that it has to pull in solutions from entirely different industries … but that’s just my opinion
I have a feeling this will also drag Linux mobile forwards.
Currently almost no one is using Linux for mobile because the lack or apps (banking for example) and bad hardware support. When developing for Linux becomes more and more attractive this might change.
> When developing for Linux becomes more and more attractive this might change.
If one (or maybe two) OSes win, then sure. The problem is there is no "develop for Linux" unless you are writing for the kernel.
Each distro is a standalone OS. It can have any variety of userland. You don't develop "for Linux" so much as you develop "for Ubuntu" or "for Fedora" or "for Android" etc.
If I'm not mistaken this has been greatly facilitated by the recent bpf based extension mechanism that allows developers to go crazy on creating schedulers and other functionality through some protected virtual machine mechanism provided by the kernel.
To be fair proton is based on DXVK which is some guy’s project because he wanted to play nier automata on Linux.
The guy is Philip Rebohler.
> Valve is practically singlehandedly dragging the Linux ecosystem forward in areas that nobody else wanted to touch.
I'm loving what valve has been doing, and their willingness to shove money into projects that have long been under invested in, BUT. Please don't forget all the volunteers that have developed these systems for years before valve decided to step up. All of this is only possible because a ton of different people spent decades slowly building a project, that for most of it's lifetime seemed like a dead end idea.
Wine as a software package is nothing short of miraculous. It has been monumentally expensive to build, but is provided to everyone to freely use as they wish.
Nobody, and I do mean NOBODY would have funded a project that spent 20 years struggling to run office and photoshop. Valve took it across the finish line into commercially useful project, but they could not have done that without the decade+ of work before that.
Long before Valve there was CrossOver which sold a polished version of Wine making a lot of Windows only enterprise software work on Linux.
I'm sure there have been more commercial contributors to Wine other than Valve and CodeWeavers.
Let's be honest
Linux (and its ecosystem) sucks at having focus and direction.
They might get something right here and there, especially related to servers, but they are awful at not spinning wheels
See how wayland progress is slow. See how some distros moved to it only after a lot of kicking and screaming.
See how a lot of peripherals in "newer" (sometimes a model that's 2 or 3 yrs on the market) only barely works in a newer distro. Or has weird bugs
"but the manufacturers..." "but the hw producers..." "but open source..." whine
Because Linux lacks a good hierarchy at isolating responsibility, otherwise going for a "every kernel driver can do all it wants" together with "interfaces that keep flipping and flopping at every new kernel release" - notable (good) exception : USB userspace drivers. And don't even get me started on the whole mess that is xorg drivers
And then you have a Ruby Goldberg machine in form of udev dbus and what not, or whatever newer solution that solves half the problems and create another new collection of bugs.
Honestly I can't see it remaining tenable to keep things like drivers in the kernel for too much longer… both due to the sheer speed at the industry moves and due to the security implications involved.
Man, if only meta would give back, oh and also stop letting scammers use their AI to scam our parents, but hey, that accounted for 10% of their revenue this last year, that's $16 BILLION.
Like them or not - when it comes to the Linux kernel they are one of the biggest contributors for many years now.

> This is the best kind of open source trickledown.
We shouldn't be depending on trickledown anything. It's nice to see Valve contributing back, but we all need to remember that they can totally evaporate/vanish behind proprietary licensing at any time.
They have to abide by the Wine license, which is basically GPL, so unless they’re going to make their own from scratch, they can’t make the bread and butter of their compat layer proprietary
That's why the anti-GPL push is so harmful. Specially in the Rust ecosystem
Can it vanish behind proprietary licensing? Pretty sure most of Valve’s stuff is under GPL so they can’t exactly evaporate that away.
How? It's GPL.
> SCX-LAVD has been worked on by Linux consulting firm Igalia under contract for Valve
It seems like every time I read about this kind of stuff, it's being done by contractors. I think Proton is similar. Of course that makes it no less awesome, but it makes me wonder about the contractor to employee ratio at Valve. Do they pretty much stick to Steam/game development and contract out most of the rest?
Igalia is a bit unique as it serves as a single corporate entity for organizing a lot of sponsored work on the Linux kernel and open source projects. You'll notice in their blog posts they have collaborations with a number of other large companies seeking to sponsor very specific development work. For example, Google works with them a lot. I think it really just simplifies a lot of logistics for paying folks to do this kind of work, plus the Igalia employees can get shared efficiency's and savings for things like benefits etc.
Oh ok, so Igalia owns the developer sweatshops now. Got it.
It's a cooperative sweatshop in that sense.
This isn’t explicitly called out in any of the other comments in my opinion so I’ll state this. Valve as a company is incredibly focused internally on its business. Its business is games, game hardware, and game delivery. For anything outside of that purview instead of trying to build a huge internal team they contract out. I’m genuinely curious why other companies don’t do this style more often because it seems incredibly cost effective. They hire top level contractors to do top tier work on hyper specific areas and everyone benefits. I think this kind of work is why Valve gets a free pass to do some real heinous shit (all the gambling stuff) and maintain incredible good will. They’re a true “take the good with the bad” kind of company. I certainly don’t condone all the bad they’ve put out, and I also have to recognize all the good they’ve done at the same time.
Back to the root point. Small company focused on core business competencies, extremely effective at contracting non-core business functions. I wish more businesses functioned this way.
Yeah, I suppose this workflow is not for everyone. I can only imagine Valve has very specific issue or requirements in mind when they hire contractors like this. When you hire like this, i suspect what one really pay for is a well known name that will be able to push something important to you to upstream linux. Its the right way to do it if you want it resolved quickly. If you come in as a fresh contributor, landing features upstream could take years.
Small company doesn't have the capital to contract out library work like that. Same story as it's always been
Whats the bad practices valve is doing in gambling?
Their games and systems tie into huge gambling operations on 3rd party sites
If you have 30mins for a video I recommend People Make Games' documentary on it https://www.youtube.com/watch?v=eMmNy11Mn7g
Yeah, im sorry. Valve is the last company people should be focusing for this type of behavior. All the other AAA game companies use these mechanics to deliberate manipulate players. IMHO valve doesn't use predatory practices to keep this stuff going.
How much of the video did you watch? I'm not aware of other game companies that enable 3rd party integrations into their item systems. This isn't just "lootboxes bad" - it's Valve profiting from actual gambling happening on external sites.
Just because they weren’t the first mover into predatory practices doesn’t mean they can’t say no to said practices. Each actor has agency to make their own operating and business decisions. Is Valve the worst of the lot? Absolutely not. But it was still their choice to implement.
What makes Valve special is that they were the first mover on those practices like lootboxes, gamepasses... but they never pushed it as far as the competition where it became predatory.
Loot box style underage gambling in their live service games - TF2 hats, counterstrike skins, "trading cards", etc etc
Lootboxes comes to mind.
I feel like I rarely see contacting out work go well. This seems like an exception
The .308 footgun with software contracting stems from a misunderstanding of what we pay software developers for. The model under which contracting seems like the right move is "we pay software developers because we want a unit of software", like how you pay a carpenter to build you some custom cabinets. If the union of "things you have a very particular opinion about, and can specify coherently" and "things you don't care about" completely cover a project, contracting works great for that purpose.
But most of the time you don't want "a unit of software", you want some amorphous blob of product and business wants and needs, continuously changing at the whims of business, businessmen, and customers. In this context, sure, you're paying your developers to solve problems, but moreover you're paying them to store the institutional knowledge of how your particular system is built. Code is much easier to write than to read, because writing code involves applying a mental model that fits your understanding of the world onto the application, whereas reading code requires you to try and recreate someone else's alien mental model. In the situation of in-house products and business automation, at some point your senior developers become more valuable for their understanding of your codebase than their code output productivity.
The context of "I want this particular thing fixed in a popular open source codebase that there are existing people with expertise in", contracting makes a ton of sense, because you aren't the sole buyer of that expertise.
If you have competent people on both sides who care, I don't see why it wouldn't work.
The problem seems, at least from a distance, to be that bosses treat it as a fire-and-forget solution.
We haven't had any software done by oursiders yet, but we have hired consultants to help us on specifics, like changing our infra and help move local servers to the cloud. They've been very effective and helped us a lot.
We had talks though so we found someone who we could trust had the knowledge, and we were knowledgeable enough ourselves that we could determine that. We then followed up closely.
Most companies that hiring a ton of contractors are doing it for business/financial reporting reasons. Contractors don't show up as employees so investors don't see employee count rise so metric of "Revenue/Employee" ratio does not get dragged down and contractors can be cut immediately with no further on expenses. Laid off employees take about quarter to be truly shed from the books between severance, vacation payouts and unemployment insurance.
I think your first 2 sentances are pretty common issues though.
Valve contracts out to actually competent people and companies rather than giant bodycount consulting firms.
Not to mention the code being open source & in need to be accepted upstream to be actually useful in the long term.
I've seen both good and bad contractors in multiple industries.
When I worked in the HFC/Fiber plant design industry, the simple act of "Don't use the same boilerplate MSA for every type of vendor" and being more specific about project requirements in the RFP makes it very clear what is expected, and suddenly we'd get better bids, and would carefully review the bids to make sure that the response indicated they understood the work.
We also had our own 'internal' cost estimates (i.e. if we had the in house capacity, how long would it take to do and how much would it cost) which made it clear when a vendor was in over their head under-bidding just to get the work, which was never a good thing.
And, I've seen that done in the software industry as well, and it worked.
That said, the main 'extra' challenge in IT is that key is that many of the good players aren't going to be the ones beating down your door like the big 4 or a WITCH consultancy will.
But really at the end of the day, the problem is what often happens is that business-people who don't really know (or necessarily -care-) about specifics enough unfortunately are the people picking things like vendors.
And worse, sometimes they're the ones writing the spec and not letting engineers review it. [0]
[0] - This once led to an off-shore body shop getting a requirement along the lines of 'the stored procedures and SQL called should be configurable' and sure enough the web.config had ALL the SQL and stored procedures as XML elements, loaded from config just before the DB call, thing was a bitch to debug and their testing alone wreaked havoc on our dev DB.
Igalia isn’t your typical contractor. It’s made up of competent developers that actually want to be there and care to see open source succeed. Completely different ball game.
Nope. Plenty of top-tier contractors work quietly with their clientele and let the companies take the credit (so long as they reference the contractor to others, keeping the gravy train going.)
If you don't see it happening, the game is being played as intended.
Valve is actually extremely small, I've heard estimates at around 350-400 people.
They're also a flat organization, with all the good and bad that brings, so scaling with contractors is easier than bringing on employees that might want to work on something else instead.
300 people isn’t “extremely small” for a company. I don’t work with/for companies over 100 people, for example, and those are already quite big.
Of course smaller companies exist — there are 1 person companies! But in a world where many tech companies have 50,000+ employees, 300 is much closer to 100 or 10 and they can all be considered small.
And then you consider it in context: a company with huge impact, brand recognition, and revenue (about $50M/employee in 2025). They’ve remained extremely small compared to how big they could grow.
I think a better way to think of it is in terms of revenue per employee. Valve is WAY up there.
the implied observation is that valve is extremely small relative to what it does and how big most people would expect it to be
Proton is mainly a co-effort between in-house developers at Valve (with support on specific parts from contractors like Igalia), developers at CodeWeavers and the wider community.
For contextual, super specific, super specialized work (e.g. SCX-LAVD, the DirectX-to-Vulkan and OpenGL-to-Vulkan translation layers in Proton, and most of the graphics driver work required to make games run on the upcoming ARM based Steam Frame) they like to subcontract work to orgs like Igalia but that's about it.
Valve is known to keep their employee count as low as possible. I would guess anything that can reasonably be contracted out is.
That said, something like this which is a fixed project, highly technical and requires a lot of domain expertise would make sense for _anybody_ to contract out.
They seem to be doing it through Igalia, which is a company based on specialized consulting for the Linux ecosystem, as opposed to hiring individual contractors. Your point still stands, but from my perspective this arrangement makes a lot of sense while the Igalia employees have better job security than they would as individual contractors.
This is how "Company funding OSS" looks like in real life.
There have been demands to do that more on HN lately. This is how it looks like when it happens - a company paying for OSS development.
It would be a large effort to stand up a department that solely focuses on Linux development just like it would be to shift game developers to writing Linux code. Much easier to just pay a company to do the hard stuff for you. I'm sure the steam deck hardware was the same, Valve did the overall design and requirements but another company did the actual hardware development.
Speaking for myself, Valve has been great to work with - chill, and they bring real technical focus. It's still engineers running the show there, and they're good at what they do. A real breath of fresh air from much of the tech world.
They probably needed some point expertise on this one, as they build out their teams.
I don't know what you're trying to suggest or question. If there is a question here, what is it exactly, and why is that question interesting? Do they employ contractors? Yes. Why was that a question?
Wut.
Valve has a weird obsession with maximizing their profit-per-employee ratio. There are stories from ex-employees out on the web about how this creates a hostile environment, and perverse incentives to sabotage those below you to protect your own job.
I don't remember all the details, but it doesn't seem like a great place to work, at least based on the horror stories I've read.
Valve does a lot of awesome things, but they also do a lot of shitty things, and I think their productivity is abysmal based on what you'd expect from a company with their market share. They have very successful products, but it's obvious that basically all of their income comes from rent-seeking from developers who want to (well, need to) publish on Steam.
There are numerous other ways to publish games. Is it really rent-seeking to own and maintain the most popular game publishing platform?
It's worth mentioning that sched_ext was developed at Meta. The schedulers are developed by several companies who collaborate to develop them, not just Meta or Valve or Italia and the development is done in a shared GitHub repo - https://github.com/sched-ext/scx.
That's the magic of open source. Valve can't say ohh noes you need a deluxe enterprise license.
In this case yes, but on the other hand Red Hat won't publish the RHEL code unless you have the binaries. The GPLv2 license requires you to provide the source code only if you provide the compiled binaries. In theory Meta can apply its own proprietary patches on Linux and don't publish the source code if it runs that patched Linux on its servers only.
RHEL source code is easily available to the public - via CentOS Stream.
For any individual RHEL package, you can find the source code with barely any effort. If you have a list of the exact versions of every package used in RHEL, you could compose it without that much effort by finding those packages in Stream. It's just not served up to you on a silver platter unless you're a paying customer. You have M package versions for N packages - all open source - and you have to figure out the correct construction for yourself.
Can't anyone get a RHEL instance on their favorite cloud, dnf install whatever packages they want sources of, email Redhat to demand the sources, and shut down the instance?
RHEL specifically makes it really annoying to see the source. You get a web view.
This violates the GPL, which explicitly states that recipients are entitled to the source tree in a form suitable for modification -- which a web view is not.
The source trees in a form suitable for modification (and pull requests) are here:
https://gitlab.com/redhat/centos-stream/rpms
it's not the only way they offer the sauce through
Don't forget RH is owned by IBM.
Honestly just hearing this makes me want to get all their binaries, request the code, scrape it with OCR and upload it somewhere
But that would be silly, because all of the code and binaries is already available via CentOS Stream. There's nothing in RHEL that isn't already public at some point via CentOS Stream.
There's nothing special or proprietary about the RHEL code. Access to the code isn't an issue, it's reconstructing an exact replica of RHEL from all of the different package versions that are available to you, which is a huge temporal superset of what is specifically in RHEL.
I'm more surprised that the scheduler made for a handheld gaming console is also demonstrably good for Facebook's servers.
Latency-aware scheduling is important in a lot of domains. Getting video frames or controller input delivered on a deadline is a similar problem to getting voice or video packets delivered on a deadline. Meanwhile housecleaning processes like log rotation can sort of happen whenever.
I mean, part of it is that Linux's default scheduler is braindead by modern standards: https://en.wikipedia.org/wiki/Completely_Fair_Scheduler
Part of that is the assumption that Amazon/Meta/Google all have dedicated engineers who should be doing nothing but tuning performance for 0.0001% efficiency gains. At the scale of millions of servers, those tweaks add up to real dollar savings, and I suspect little of how they run is stock.
This is really just an example of survivorship bias and the power of Valve's good brand value. Big tech does in fact employ plenty of people working on the kernel to make 0.1% efficiency gains (for the reason you state), it's just not posted on HN. Someone would have found this eventually if not Valve.
And the people at FB who worked to integrate Valve's work into the backend and test it and measure the gains are the same people who go looking for these kernel perf improvements all day.
CFS was replaced by EEVDF, no?
I vaguely remember reading when this occurred. It was very recent no? Last few years for sure.
> The Linux kernel began transitioning to EEVDF in version 6.6 (as a new option in 2024), moving away from the earlier Completely Fair Scheduler (CFS) in favor of a version of EEVDF proposed by Peter Zijlstra in 2023 [2-4]. More information regarding CFS can be found in CFS Scheduler.
Ultimately, CPU schedulers are about choosing which attributes to weigh more heavily. See this[0] diagram from Github. EEVDF isn't a straight upgrade on CFS. Nor is LAVD over either.
Just traditionally, Linux schedulers have been rather esoteric to tune and by default they've been optimized for throughput and fairness over everything else. Good for workstations and servers, bad for everyone else.

Parent's article says
> Starting from version 6.6 of the Linux kernel, [CFS] was replaced by the EEVDF scheduler.[citation needed]
I mean.. many SteamOS flavors (and Linux distros in general have) have switched to Meta's Kyber IO scheduler to fix microstutter issues.. the knife cuts both ways :)
Kyber is an I/O scheduler. Nothing to do with this article.
The comment was perfectly valid and topical and applicable. It doesn't matter what kind of improvement Meta supplied that everyone else took up. It could have been better cache invalidation or better usb mouse support.
Well if you think about it, in this case the license is the 30% cut on every game you purchase on steam.
I've been using Bazzite Desktop for 4 months now and it has been my everything. Windows is just abandonware now even with every update they push. It is clunky and hard to manage.
Isn't bazzite a gaming focused distribution ? It seems weird to install it on a PC that does 'my everything'.
I wouldn't make excel spreadsheet on the steam deck for instance.
Bazzite is advertised for gamers, however from my understanding it's just Fedora Atomic wrapped up to work well on steamdeck adjacent hardware and gaming is a top priority. You'd still be receiving the same level of quality you would expect from Fedora/RHEL (I would think).
Why not? It has full desktop mode with Plasma and can be docked like PC
I'm curious how this came to be:
> Meta has found that the scheduler can actually adapt and work very well on the hyperscaler's large servers.
I'm not at all in the know about this, so it would not even occur to me to test it. Is it the case that if you're optimizing Linux performance you'd just try whatever is available?
almost certainly bottom-up: some eng somewhere read about it, ran a test, saw positive results, and it bubbles up from there. this is still how lots of cool things happen at big companies like Meta.
Maybe better to go straight to the source and bypass Phoronix blogspam: https://www.youtube.com/watch?v=KFItEHbFEwg

It’s a recording of a talk. Feel free to point out other sources but there doesn’t seem like much to object to here.
Phoronix is blogspam?!
yeah thats kinda harsh, phoronix is a good oss news aggregator at the very least, and the PTS is a huge boon for "whats the best bang for buck llvm build box" type of question (which is very useful!)
I'm struggling to understand what workloads Meta might be running that are _this_ latency-critical.
According to the video linked somewhere in this thread indicates WhatsApp Erlang workers that want sub-ms latency.
It's definitely for ads auctions
Meta is a humongous company. Any kind of latency has to have a business impact.
It's Meta. They always push to be that fast on paper, even when it's costly to do and doesn't really need it.
If you have 50,000 servers for your service, and you can reduce that by 1 percent, you save 50 servers. Multiply that by maybe $8k per server and you have saved $400k,you just paid for your self for a year. With meta the numbers are probably a bit bigger.
LOL (I used to work for Meta, so appreciate the facetious understatement)
That's not how it works though. Budgets are annual. A 1% savings of cpu cycles doesn't show up anywhere, it's a rounding error. They don't have a guy that pulls the servers and sells them ahead of the projection. You bought them for 5 years and they're staying. 5 years from now, that 1% got eaten up by other shit.
You're wrong about how services that cost 9+ figures to run annually are budgeted. 1% CPU is absolutely massive and well measured and accounted for in these systems.
You don't buy servers once every 5 years. I've done purchasing every quarter and forecasted a year out. You reduce your services budget for hardware by the amount saved for that year.
Interesting to see server workloads take ideas from other areas. I saw recently that some of the k8s specific os do their updates like android devices
You mean immutable?
That wasn't what I was thinking about. There's a phrase for it using active and back up partitions but I can't find what it's called
A/B updates?
Omarchy should adopt the SCX-LAVD scheduler as its default, it helps conserve power on laptops.

Posting an AI summary is about as useful as posting Google search results. We can all do it, we don't need anyone to do it for us.
As well as the points already raised by others, I'd like to make the point that we should be encouraging people to prompt LLMs themselves rather than just accepting the outputs of others. As a social norm, this will make society more robust to misinformation and deception, as it will result in fewer people trusting outputs without knowing how the LLM was actually prompted.
This probably doesn't really matter in this context, but I think it's a general best practice worth reinforcing whenever possible.
If someone want to ask an LLM about something, good for them, but there's no need to paste its content over the internet, disclosed or not.
