Windows "Windows is indeed slower than other operating systems in many scenarios, and the gap is worsening." That's one way to start an insider explanation of why Windows' performance isn't up to snuff. Written by someone who actually contributes code to the Windows NT kernel, the comment on Hacker News, later deleted but reposted with permission on Marc Bevand's blog, paints a very dreary picture of the state of Windows development. The root issue? Think of how Linux is developed, and you'll know the answer.

I'm not going to explain anything anymore, because your counter argument is "it works for me" so far.

from the looks of it it works for a lot of purposes, not just him.

Huh? From what I can tell you haven't explained anything, you made a blanket statement of 'Stable API/ABIs are good engineering like it or not' which totally disregards reality, which is that stable api/abi's are NOT automatically 'good engineering' if those stable ABI/API's turn out to suck and then you are stuck with them.

I doubt there is a single long term 'stable' API/ABI today that would look the way it does (in many cases probably not even remotely) had the original developers been able to go back in time and benefit from what they know now.

So it's a balance, will you keep code from 'yesterday' which 'today' turned out to be a crappy solution in order to maintain compability or will you allow yourself to break it and force improved changes upon those interfacing with your solution?

The kernel devs chose the balance of being able to break anything inside the kernel, while keeping userland interfaces intact.

This is not a perfect solution because there simply is no perfect solution, but it means that their changes has practically zero impact on user space (which certainly limits the improvements they can make) while allowing them free reign to improve within the kernel space.

And since the kernel is monolithic this means there's a ton of in-kernel functionality which can be enhanced without breaking compability, the exceptions in practice are those few proprietary drivers residing outside of the kernel, which needs to be maintained by their vendors against kernel ABI changes.

because your counter argument is "it works for me" so far.

Oh I think I've fleshed out my argument a lot more than that, meanwhile yours still seem very little beyond 'it doesn't work for me'.

At the end of the day, I think a simple google for "my wireless is not working anymore in <distro x>" proves the point.

While it was better than it was, it still sucks. YET Linux advocates make up all sorts of excuses why it is okay. They could have I dunno supported a legacy interface until kernel version X which wouldn't have been much effort if the internal structures are as good as you say they are. This would have given hardware companies and OEMS roadmap that they could follow.

There always been problems because they made a bad choice for desktop users and oems that may have wanted to support it. Might be a good choice for progression of the kernel itself, but it is a shit choice of desktop users, which is one of the many reasons that Linux is and will always be a failure on the desktop.

The fact of the matter is while you get up-votes on here, changing interfaces and APIs tends to piss third party developers off. If there wasn't the legal problems with the BSDs at the time, Linux wouldn't have even got off the ground because there wouldn't have been picked up as a "free" *nix like alternative.

Sadly friend that is ALL you will get because ultimately the broken driver model has become a religious element, a way to "prove the faithful" by how much they will get behind an obviously and demonstrably bad design.

Quick, how many OSes OTHER than Linux use Torvald's driver model? NONE. How many use stable ABIs? BSD,Solaris, OSX,iOS,Android,Windows, even OS/2 has a stable driver ABI.

I'm a retailer, I have access to more hardware than most and I can tell you the Linux driver model is BROKEN. I can take ANY mainstream distro, download the version from 5 years ago and update to current (thus simulating exactly HALF the lifetime of a Windows OS) and the drivers that worked in the beginning will NOT work at the end.

And before anybody says "Use LTS" that argument doesn't hold water because thanks to the again broken design by Torvalds most software in Linux is tied to the kernel so if you want more than a browser and Open Office? You WILL be forced to upgrade because "this software requires kernel x.xx" or be left behind with older non supported software. With Windows with the exception of games that require a newer version of DirectX (which is rare, most have a DX9 mode for this very reason) you can install the latest and greatest on that 10 year old XP machine and it JUST WORKS.

Again let me end with the simple fact that after NINE YEARS I'm retiring the shop netbox. That is TWO service packs and at LEAST 3000 patches and not a single broken driver, NOT ONE. If Linux wants to compete then it actually HAS to compete, not give us excuses which frankly math can prove doesn't work. Look at the "Let the kernel devs handle drivers" excuse. You have 150,000+ drivers for Linux, with a couple of hundred new devices released many Linux kernel devs are there again? if you pumped them full of speed and made them work 24/7/365 the numbers won't add up, the devs simply cannot keep up...which is of course one of the reasons to HAVE a stable ABI in the first place, so that the kernel devs can work on the kernel while the OEMs can concentrate on drivers.

Sorry for the length but this one really irks me, if you like running an OS that is rough because of reasons? Go right ahead, i wish you nothing but luck. But when you compare that broken mess to either OSX or Windows I gotta throw down the red flag and call bullshit, its not even in the same league. Oh and do NOT bring up embedded or servers as that is "moving the goalposts" and honestly i don't care how cool your OS is at webserving, I'm not selling webservers and that isn't the subject at hand. Linux is broken ON THE DESKTOP and that is what we are discussing so try to stay on topic.
