Where is the mess? Everywhere: sound, video, embedding, etc.Where is the mess? Everywhere: sound, video, embedding, etc.Posted Oct 20, 2008 8:36 UTC (Mon) by khim (subscriber, #9252)In reply to: 64bit platforms? Huge market, yes. Pure 64bit platforms without 32bit support? Don't make me laugh... by quotemstr Parent article: Linux now an equal Flash player (Linux-Watch)
I'd argue that Win32 is a horrible mess, actually, filled with compatibility kludges, automagical common control versioning, silently redirected writes to parts of the filesystem namespace, and so on. You are looking on the system from the POV of system developer. From POV of application developer lack of said automagical versioning is a mess. Why? Some examples. Sound. How well OSS emulation is working today? Oh, right, OSS API was a mess and so it can not be adequately supported. Now everyone must rewrite everything for ALSA... or may be GStreamer... or may be PulseAudio... Video. There are just two interfaces: V4L and V4L2. So if I don't need the features I can safely use V4L, right? Oh, no backward compatibility... Ok, I'll use V4L2... What? No support for some devices? So I must support both? What a mess... (Note: AFAIK this particular mess was cleaned up and now most devices support V4L2 - but for years the situation was as described). Widgets. Can I embed Qt widget in a GTK program? No? Why No? Ok. At least GTK widgets are usable in Qt (not so long ago this was impossible too). Remember the ire Windows users directed on Microsoft for discontinuing VB6? It was supported for ten years before Visual Fred replaced it! In Linux such tectonic shifts (when you can not use old APIs anymore) happen once per year or two. And rarely developers offer support for "obsolete" technologies. The only one lib which actually supports old APIs is GLibC - yes, there are occasional glitches, but you can still take old program from the era where files were limited to 2GiB and it'll work. Oh and linux kernel itself is pretty good at keeping things backward compatible... unless you'll count aforementioned "big switches" like OSS->ALSA transition or V4L->V4L2 transitions. Transitions in Windows are handles in the sane way (from the POV of
everyone who's not system developer): If there are APIv3 or APIv4 introduced along the way - it means at some point you'll have concurrect support for three or four versions of API... In linux it's done "in clean way": This is the best way to scare away ISVs and "normal" users. Who just want to use the system and not think about versions of kernel, GLibC and GTK. Who want to select API to support all currect systems (say: 2-3years old) and future systems (again: 2-3years in the future). Why this limits? It's easy: PCs average lifespan is 2-3 years. And you want your application be available for everyone who's currently using PC. So Any API must be supported for at least five years (ten is better) and for at least three years after replacement is introduced (five is better). Situation is slowly changing - but it's still far from being equal to Windows. Actually friedliness to ISV is almost directly proportional to market share: Linux is 1% (because of the aforementioned problems), Mac OS is 5-10% (it's better then Windows, but it still likes to do things like drop support for Carbon when 100% incompatible replacement was only available for eight years), and the rest is Windows (which is horrible in many ways but has excellent backward compatibility). Remember: Joe Average does not care as much for "cleannes of the architecture" - but he does care about his ability ro use old software. And ISVs like to produce software which till PC lasts. This is not an option in current Linux ecosystem - unless you'll ignore it and go with separate abstraction layer (JDK, for example).

Where is the mess? Everywhere: sound, video, embedding, etc. Posted Oct 27, 2008 0:22 UTC (Mon) by vonbrand (subscriber, #4458) [Link] No, Linux (the kernel) still supports the very first filesystem it had, and runs its very first binaries. OTOH, I once bought a MSFT game, and it did not run on the next version of Windows. Just the splash screen showed, then complete hang. This "Linux is a mess" is complete FUD. Yes, I do want my programs to run on the next (and then some) Fedora. Usually that means that they got recompiled (by my distribution or somebody else, even myself) on the way. I very rarely have any use for year-old binaries (except for some self-written programs that I just copied over and am still running as 32 bits on this 64 bits, mostly out of lazyness). And where I do need to run old binaries, I use a "enterprise" distribution; there I have a very much longer guarantee than on any Windows I've seen.
Hmm... Check your facts first, them talk Posted Oct 27, 2008 7:57 UTC (Mon) by khim (subscriber, #9252) [Link] No, Linux (the kernel) still supports the very first filesystem it had, and runs its very first binaries. The very firstsystem? Did you mean very first filesystemS? There were two: ext1 and xiafs. Both are unsupported today. As for binaries... yes, "Hello world" runs, but real binaries fail routinely. Programs which iteract with hardware (floppy, CD, sound) are expecially fragile. OTOH, I once bought a MSFT game, and it did not run on the next version of Windows. Just the splash screen showed, then complete hang.What was the name of the game and what did you do to make it work? I've found that most games can be persuaded to work in the next version of Windows if you'll just remove what copy protection software they are using. That's not a Windows problem: copy protection creators go far beyond spec. Look, I'm not saying Windows compatibility is 100% sure thing. But Microsoft thinks about compatibility! Compare with Linux: yes, there exist the way to properly support sound in old program. But it's still unmerged - six years after ALSA introduction! You can be 100% sure Microsoft will never tolerate such a huge breach of continuity. You can be 100% sure such transtion layer will be developed and introduced alongside the new interface, not some years after the fact when poor sound support will start to really hurt Linux reputation. Yes, I do want my programs to run on the next (and then some) Fedora. Usually that means that they got recompiled (by my distribution or somebody else, even myself) on the way. I very rarely have any use for year-old binaries (except for some self-written programs that I just copied over and am still running as 32 bits on this 64 bits, mostly out of lazyness). Yes, that typical Linux user attitude. But Windows user are accustomed to much longer support times. And for binaries, not for source. Some companies are still using 10-15 years old programs written in Visual Basic 2 for Windows 3.1 (that's one reason as to why Windows for x86-64 is not such a big hit: you can not use Windows 3.x programs there). And where I do need to run old binaries, I use a "enterprise" distribution; there I have a very much longer guarantee than on any Windows I've seen.Have you actually used Enterprise Windows? Let's compare, shell we: Windows2000: introduced in 2000 (duh), EOL July 13, 2010 RHEL2.1: introduced in 2002, EOL May 31, 2009 Windows2003: introduced in 2003 (duh), EOL July 14, 2015 RHEL4: introduced in 2005, EOL February 29, 2012 RHEL5: introduced in 2007, EOL March 31, 2014 Windows2008: introduced in 2008 (duh), EOL October 07, 2018 Sorry, but if you'll compare enterprise Linux distributions with what Microsoft is offering... you'll find Linux sorely lacking. RHEL and Ubuntu LTS fall far short of what the Microsoft is offering where SLES is barely matching it (but if I wanted an Microsoft-controlled OS I'd used Windows). Don't try to rebuff FUD with FUD of your own - it backfires. P.S. Note: I'm not saying Linux is hopeless. On the contrary: Linux is slowly moving in right direction. But to fix the problem you first must admit yet. Sadly Linux developers tend to ignore it and blow up every time points it out. That's not the way to win ISVs and users.

This is downright bullshit. There's OSS emulation in ALSA and it works most of the time. PulseAudio has padsp for OSS-only applications and an ALSA plugin for ALSA-only applications.

> 1. APIv1 is introduced.
So please, just stop making up random bullshit here.
