Video Interview With Linus On Linux 2.7
daria42 writes "ZDNet Australia has put up a video interview of Linux creator Linus Torvalds talking about the kernel development process, explaining why the unexpected resilience of kernel version 2.6 has delayed the move to 2.7." From the interview: "One of the original worries was that we would not be able to make big changes within the confines of the development model... I always said that if there is something so fundamental that everything will break then we will start at 2.7 at that point... We have been able to do fairly invasive things even while not actually destabilizing the kernel... Having stable and unstable in parallel: I think it used to be a great model, and I think we may see that the kernel has actually become more mature and stable and it just doesn't seem to be that great a model, for the kernel."
How difficult is it to release a video about linux kernel development in a format that is easy to watch by people running linux? At least use flash 7...no need to blow their minds talking about ogg/theora.
Visit the download page from a Linux browser and you can download Flash 9 for Linux now. And P.S. the beta was out for months before this was...
STOP . AMERICA . NOW
Flash 8 has been shown to destabilize the 2.6 kernel... Supposedly it will play nicely with the 2.7 kernel, though.
Having stable and unstable in parallel: I think it used to be a great model
It certainly works when dual-booting.

I've never bothered to look at a video interview on the net (part often not being able to, part just not liking video on my desktop, part that the moving images distract me from all the multitasking I somehow can do while reading), but if someone could post a transcript of what was said, I'd be sure to read it :)
I can't watch the video due on that site, but I really am not certain what he is trying to say from the text I can read.
Does he want to sacrifice stability for innovativeness in kernel 2.7 or does he think that things are going fine the way they are right now with a stable and an unstable kernel?
true...
oh! the irony...
Politics is Treachery, Religion is Brainwashing
Does it contain anything inflammatory about the GPL v3? If not, I'm not interested. :]
He's basically saying that no one is really developing a 2.7 kernel because 2.6 is extremely stable even with whatever experimentation they've done. He states that theres been times where they've gone over the 2 month release cycle because of the "big changes" they've done on the kernel. He states that unstable next to stable used to be a good model but it isn't good anymore. He states that if there was a 2.7 kernel they'd have to do all sorts of backporting to get whatever fixes on the 2.7 kernel to work on the 2.6 kernel.
In my opinion, the real reason for no 2.7 is:
If we open up an unstable branch, I have less testers. --Linus Torvalds
I'm not saying the 2.6 series is unstable or anything, either. However as I watch Linux's development from the sidelines, I get the impression that most policy decisions Linus makes are designed to make his life easier. See also: Bitkeeper.
The resiliency of the 2.6 kernel is most certainly due to corporate involvement in the development of and support for Linux. Companies can't design, build, test, and support product for a moving target.
If anyone wanted to seriously break the Linux kernel ABI, I don't think corporate interests or major distros would support it or follow.
OSes or platforms seem to change rapidly up until the point they reach a critical mass - at which point, the next ABI change is cause for general revolt. After that, $ENTITY learns their lesson and vows to never significantly break backwards compatibility again.
Flash Player 9 is avaliable for linux. I was going to gripe about it too, but there are at least two posts above which link to the download site.
Works fine for me, and I'm using Flash 9 on an Athlon 64.
Sit, Ubuntu, sit. Good dog.
explaining why the unexpected resilience of kernel version 2.6 has delayed the move to 2.7.
Uh...resilience?
2.6 releases have "shipped" numerous times with some serious bugs, probably because Linus and company have let lots of people slip major new features into the 2.6 kernel, when it's supposed to be stable. 2.6 kernels regularly make it SEVERAL "point" releases into each point release:
Go and look at the timestamps on 'em on ftp.kernel.org. Some of the sub-versions are just a few days apart. How the hell are end-users supposed to know when the kernel is ACTUALLY useable, if there are THIRTY SEVEN bug-fix releases?
One of the more amazing bugs involved a bug in md that would hose raid partitions, and I assure you, it was not the only serious filesystem bug. I lost a reiserfs partition thanks to a half-baked 2.6 release.
Please help metamoderate.
Flash 9 for Linux has been available for at least a month or so, practically forever. Occasionally the sound stops and I have to restart Firefox, but that's the worst of my problems.
I thought the odd numbers were "run with it" kernels. Leave the even number kernels static for bugfixing only.
How about 2.9 then. Blue sky how would you design an OS for all the cheap commodity hardware around.

"...2.6 kernel is still the development kernel...."
can anyone post this "fragmented" and unaccessible interview video to youtube or google video as one or two big file(s)?
but not on a 64-bit operating system, or at least not a 64-bit version of firefox
Not that I'm a fan of Adobe's flash player. I still open a 32 bit browser whenever I absolutely need flash, and use a 64 bit browser the rest of the time. One of the main reasons I'm still using my old SoundBlaster Live! is because it has hardware mixing, and gets around problems like what it sounds you are experiencing.
"'Yrch!' said Legolas, falling into his own tongue."
It's Easy, I'm assuming you're using Firefox, so fire up Nano and open the file "/etc/firefox/firefoxrc" (as root)
Add this line: FIREFOX_DSP="aoss" (remove FIREFOX_DSP=)
Install the alsa-oss package.
Restart FF, and you are playing sound!
"Free software" is a matter of liberty, not price.
Amen.
So does any one wonder if there is ever going to be a 2.8 or a 3.0 Kernel?
This is just speculation but...
I'm guessing as soon as Ingo Molnar and friends get the real time premption patch fully
merged into the mainline we'll see a new Kernel release (not a 2.6.x+1)
Money is the root of all evil?

Restart FF, and you are playing sound! Um, I'm not sure what planet you are living on, but that's not "easy". It's tedious and frustrating.

Flash 9 for Linux uses Alsa (and only Alsa, no OSS anymore), and it "plays nice" with other Alsa-using sound apps just fine.
not on my machine. the video frezes at 3/4 of the playthru and the sound is gone. to make it more interesting the whole browser has to be restarted to get anything in flash to work again. i'll wait for the next version, perhaps in that it will work. tested with both fx 1.5 and 2.0, none of them wanted to work properly with it, kernel is 2.6.18 no other problem with alsa sound anywhere else, go figure.
and some smartkickass javascript checks still don't realize that you have version 9 which is greater than 8, and go on complaining and redirect you somewhere else.
I'd tell you the chances of this story being a dupe, but you wouldn't like it.

Creationist Textbook Stickers Declared Unconstitutional by CowboyNeal
And yes, I use Linux (among other OS'es). Have been using it since 1999, and I'm a card-carrying member of a national LUG. But anyone who says that "It's easy, just edit this text file and install these apps and you are all set" is totally, 100% missing the point. Tasks like that are way beyond the capabilities of most users. They just want their systems to work. And if it's so easy to fix the problem, why isn't it fixed by default? Why are tasks like that left to the user to figure out?

VFS probably needs to be addressed. Reiserfs4 sort of exposed some of the issues. There are others though. To my knowledge ext2/3 are the only OSes that actually code strcitly against VFS and the other layers. XFS, JFS, Reiserfs, etc.. are all hacked in to it. If you follow the kernel list, you'll see nobody uses JFS and XFS seems to have regular crash reports. Upon using it myself (for 5 years) it has memory leaks, it routinely has trouble with new kernels. There have been regular performance regressions. Now, I don't really care about the filesystem itself that much but it seems fundamentally broken to me that a non-experimental filesystem has such routine problems. Either the API is uses is broken, the filesystem is broken or both. I'm becoming more inclined to think that it's VFS. This creates a circular sort of problem, you don't need VFS if ext2,3,4 are the only filesystems that are really supported, it's not nearly as important as it is treated. Either that or the process of having something included and non-experimental needs to include some kind of support aspect and maybe be rethought. So far as I can tell, IBM isn't really doing much more with JFS and nobody uses it, let's move to remove it (bummer too because it's a quite clean and elegant FS, much better than reiserfs or xfs in terms of code and design quality and cleanness.) There isn't a clean process for removing stuff from the kernel. Reiserfs is a prime example, Reiserfs3 isn't supported, time to move to remove it; it has known bugs and design flaws which are not being addressed. This particular area is more complex also because selinux depends on filesystem support, LVM behaves differently with different filesystems, different filesystems have different and variable tools support.. System filesystems need some work too, what's debugfs? configfs? How is sysfs different than configfs or procfs?
Filesystems are just an easy to see and expose portion of this problem there are other APIs which have the same issues. We retooled the build system a few years back, it's much better but there are major flaws still. There are drivers which cannot work unless loaded as a module and yet they can be linked in. There are a huge number that depend on other subsystems and you can easily misconfigure them (SATA depends on parts of SCSI. So I can static link some SATA modules in and dynamic link parts of the SCSI system in and the build system won't complain. Worse, if I break it just so, I can actually get it to build cleanly and freak out at runtime) I'm not advocating making it more difficult to hack on the kernel or add new modules to the build but it's fucked if it doens't catch that stuff. Worse, the driver is fucked if it can't be statically linked and if that's an acceptable limitation then it should be an option. (the Fusion series of RAID/SCSI/SAS type drivers is one that suffers from this problem) At the same time the build system is holy, good luck changing that without pissing off half the free world, and I don't even want to think about what would have to happen if it required a change to a .config file to take it to the next level. Part of the beauty of Linux in this regard is that it is remarkably simple to build and get involved with, there really aren't any tricks or anything to building it. This is something else where there needs to be a support component. There are good companies with well supported drivers and there are orphans. I'd rather have modules marked as supported or unsupported than whether or not they are GPL clean or tainted, I'd like to see that
Well I use Debian Etch and Ubuntu Dapper and Edgy on several different systems and I've never had a problem with what you are describing. My sound in the browser "Just Works".
Now I don't doubt that yours is not working, for whatever reason. I guess my point is usually things just work for me using Debian or Ubuntu. Sometimes they don't, rarely these days, but it happens. When things don't work I occassionly have to do something odd or tedious to get it to work again. But this is true of any OS and I've spent at least as long in Windows trying to get something that should have been easy to work and it's not always simple.

Fortunately Flash 9 is now available (at least for i386) and so this particular piece of config-file cargo-culting can by forgotten, and sink back to the depths of the Pit from whence it came.
Actually, I dug this up from Kubuntu Dapper, and the previous one (sorry, I forgot the name of it). It's a fluke that only happens with Intel onboard AC`97 audio chips. (My *other* computer has no issues, just this one with the 865PERL mobo).
I agree it's a PITA for newbies, but hardly something so hard that it can't be fixed.
"Free software" is a matter of liberty, not price.
OSS sound is deprecated? So much for ALSA just being an alternative, now it is crammed down our throats.
ALSA is LINUX specific, OSS is cross platform. We are taking a step back just because the high end audio people want extra features.
Make it an OSS extension, or just go ahead with the ALSA push and let's make Linux specific APIs and drop any pretense of UNIX/POSIX compatibility.
Just because it CAN be done, doesn't mean it should!
Frankly, in this area, "UNIX/POSIX" compatibility can go fuck itself. Does POSIX even specify audio output interfaces? Did "UNIX" (System V? BSD?) even ever have sound output?
ALSA is not only desired by high-end audio users. All users want basic features such as the ability for two programs to use the sound card at the same time. ALSA provides this (part of alsa-lib) and OSS does not.
ALSA is not necessarily Linux-specific. As far as application programs are concerned, ALSA is merely a stable program library (libasound.so.2). Nothing stops you from porting alsa-lib to another platform, or implementing another library with the same interface. If would probably be quite easy to get it working today, by configuring alsa-lib to use the pcm plugin that talks to Pulse Audio server, which can output to OSS or many other sound systems/devices/interfaces.
Finally, if you bothered to do the most basic research about the i386 GNU/Linux Flash player, you would have found out that it is Adobe's plan to separate out the GNU/Linux-specific parts of the player into a separate library with a stable interface. Anyone (who uses i386) would then be able to implement their own platform-specific replacement and thus get the Flash player running on their platform.
I believe the point of the post was that the operation was abstract and required extra knowledge, not that there are better/worse alternatives. The point is, you still have to learn/know something. The only way to avoid it is to make it work out of the box. Power users and people interested in stuff like that (geeks) may not care. But for everyone else it's like their car broke down in the middle of the road. They have no way of fixing it other than calling a mechanic or learning more about the car themselves--neither of which they are interested in except that it is the only way to get the car working again.
"I've never had a problem with what you are describing."
I'm not describing it, others are. My Linux-box has died due to hardware-failure, so this issue does not affect me sinse I don't have a working Linux-installation at all. But the point is that no-one should tell other how "easy" it is to fix a problem, when all you have to do is to edit few text-files and install few apps. First of all, the problem should not exist at all. Second: Editing text-files and installing apps is not "easy" for regural users. It's easy for powerusers, but for that soccer-mom down the street it's too much.

You're totally right on this point, but I [i]still[/i] wouldn't classify editing one line in a text file and then typing one command as "tedious and frustrating".
I've never claimed it's all happy automagical justworksness, however one diff would remove this insurmountable hurtle and since the GGP or wherever it was seems to be relatively technologically savvy, one bug report to his distribution could fix this for all.
And yes, I use Linux (among other OS'es). Have been using it since 1999, and I really don't care if my grandma uses it.
What does "the soccer mom down the street" do when Windows gets spyware? A virus? What if a driver downloaded from Windows Automatic Updates hoses the video card?
You seem to think that any and all things to do with computers should be easy to fix. Their not always. Fixing the issue with the sound sounded pretty damn easy to me compared to some things I've had to deal with on both Linux and Windows.
Not to mention your comment about your box dieing from a hardware failure. Hearing that I'm thinking "so this guy put Linux on an old, dieing box and is wondering why it sucked?". Have you tried a modern distro on a modern PC? "Look mom! No config files to edit!"
Creationist Textbook Stickers Declared Unconstitutional by CowboyNeal
OK sure, I can agree with that. But it seems from reading the post and especially the follow ups that the guy threw Linux on an old box with the expectation that he wouldn't like it.
To continue your car analogy (love the car analogies!) it's like someone driving a beat up, 89 Nova and wondering why it so hard to keep going. Oh and then blaming Ford for selling him a POS.
