H.264 is the codec used in youtube when you play videos with the flash player. This HTML5 video viewer just reuses theses videos, only the html client code changes. Using other codec means reencoding all their videos in a different video format, which must not be easy. Specially when the alternatives are worse (theora) or not ready (dirac).
Corbet is the editor of LWN.net and has contributed some patches to the kernel, but i doubt he would accept to be called "key contributor". IMHO his best description would be "the best linux kernel journalist".
That's not really communism, that's collectivism. Collectivism fits quite well with capitalism, if it's people who decide themselves to share their private properties with other people. In fact this is the basis of family, the key structure of our society. Buying shares of a company is also a kind of collectivism.
Communism is a completely different beast. Communism thinks that today's human beings have been poisoned by our ugly ugly ugly capitalist society, so our society needs to forget all the bad things it knows, and be re-educated to be good socialist. That's why a dictatorship is needed (well, they don't call it dictatorship, of course) - people should not have freedom until they are reeducated, becase their minds are poisoned. Even when they think they're being good citiziens (say, you contract a worker, and pay him well), they are being opressors. It's neccesary to take away their freedom, so that they don't make bad things like that. Once the state (ruled by a few intellectuals who know what should be right and what should be wrong in a perfect socialist world) has reeducated the society, the central state can disappear (or not: Marx did not really tell what would happen then, because nobody would know how that world would be until it is created).
Of course, our society is not really broken, and the perfect socialist men does not exist. Childs who were educated to be a perfect socialist man happened to have the same defects we, the poisoned capitalists, have. In fact, those childs usually ended up being more anticommunist than the rest of people. That's why communism has always failed and will always fail, it always fails to reeducate the society, and the dictatorship which is supposed to be temporary never disappears.
Collectivity inside capitalism? I think that's a good thing. In fact, it's the one kind of collectiviy that I can imagine. There're indeed many ideas that could be tried, which don't even require to change any law. Communism? No thanks
Reiserfs has been undermaintained for a lot of time AFAIK. When hans started working in reiser4, he forgot completely about adding needed features to v3. The reiserfs disk format may be good, but the codebase is outdated. Ext4 has an ancient disk format in many ways, but the codebase is scalable, it uses delayed allocation, the block allocator is solid, xattrs are fast, etc etc. Reiserfs still uses the BKL, the xattr support that Suse added is said to be slow and not very pretty, it had problems with error handling etc etc...
there was a ton of computer history contained in those files.
Indeed! There're many interesting bits in these emails that explain quite well some of the things we suffer every day.
"One things I find myself wondering about is whether we shouldn't try and make the "ACPI" extensions somehow Windows specific. It seems unfortunate if we do this work and get our partners to do the work and the result is that Linux works great without having to do the work. Maybe there is no way to avoid this problem but it does bother me. Maybe we could define the APIs so that they work well with NT and not the others even if they are open. Or maybe we could patent something related to this" - Bill Gates
"One thing we have got to change in our strategy - allowing Office documents to be rendered well by others people browser is one of the most destructive things we could do to the company. We have to stop putting any effort into this and make sure that Office documents very well depends on PROPIETARY IE capabilities" - Bill Gates
Why? After opensourcing solaris and java, Sun had a great record of being opensource friendly, and they had a LOT of incentives to improve MySQL and compete with Oracle. Sun also was a Big Company that could invest in MySQL more money than MySQL alone could even dream.
Oracle is a different story. They make a lot of their money from a bussines based in software licenses of their closed-source database. Opensource competence kills their bussiness model. They clearly don't have many incentives to make MySQL compete with Oracle - unless bankrupcy is a bussiness model. And MySQL CAN compete with Oracle long-term - look what a JokeOS Linux was some years ago, and how today it has eaten most of the Unix bussiness.
So why Monty is an hypocrite? It's Sun who has sold out, not Monty. The decisions where Monty was involved were to make mysql BETTER. How could he expect that Sun was going to die? Is he an hypocrite just because he wants to avoid the fall of mysql?
A motherboard with an integrated intel graphic card. They are not as fast as ATI/Nvidia, but they work great for things like desktop compositting, and the driver is the most complete and stable driver available in the FOSS world.
3D features are not really supported, but except that, most of the basic things seem to be supported - KMS, KMS-based FB, suspend/resume, dual head/randr, 2D, video...
Graphic commands - processes and transmits 2D graphic commands Video streaming - heuristically identifies video streams and transmits M-JPEG video streams Image compression - offers verios compression algorithm that were built specifically for Spice, including QUIC (based on SFALIC), LZ, GLZ (history-based global dictionary), and auto (heuristic compression choice per image) Hardware cursor - processes and transmits cursor-specific commands Image, palette and cursor caching - manages client caches to reduce bandwidth requirements Live migration - supports clients while migrating Spice servers to new hosts, thus avoiding interruptions Windows drivers - Windows drivers for QXL display device and VDI-port Multiple monitors Client for Linux and Window - can be easily ported to additional platform platforms. Two way audio - supports audio playback and captures; audio data stream is optionally compressed using CELT Encryption - using OpenSSL Two mouse modes - provides client (more user-friendly) and server (increased accuracy and fully synchronized) modes Lip-sync - synchronizes video streams with audio clocks Spice agent - running on the guest and performs tasks for the client
And how is that related to KMS? KMS is about moving mode switching to kernel, which is neccesary even for the most modern 3D cards. And the memory manager that was implemented to make it possible is also neccesary to implement correctly a modern graphic stack.
Not that long, in my opinion. I've been using Btrfs as my root filesystem (except for/boot and/home, but anyway) since the day after Fedora 12 was released (two weeks). I haven't had any problem at all with it - no hangs, not even a simple printk low-periority warning. It seems to be quite stable - i'm not surprised that they are considering (according to LWN) declaring it "ready for early adopters" in the next kernel release.
They probably can't do it easily - IE is so tied to the internal of Windows that installing a nightly IE you are touching too many internals that could break easily. And it replaces your current IE install. That's why I never test IE beta/RC releases.
Now we can see how stupid it was to tie IE so strongly to the rest of the system. If Windows was a reasonably designed piece of software, Microsoft could several versions of IE at the same time. You could try a nigthly IE9 build without deleting the stable version.
Re:Huh, they're using the Nouveau driver...

According to the feature matrix, they are already done with 2D support, video playback, dual head, Xrand, KMS and suspend/resume for all the chips, which are the neccesary functions for a functional gnome/kde desktop (minus compiz), so it's not suprising that distros are starting to include it.
-Fedora is 'too' comfortable with cutting edge changes,
That's why I'm switching from Ubuntu to Fedora - I want cutting edge stuff, but not unstable enought to scare me and break all my stuff. Many fedora package maintainers are red hat programmers who are also important kernel/libc/gcc/gnome/pulseaudio/x.org hackers, they drop cutting edge stuff but it's their stuff and they fix it quickly. Ubuntu packagers however are usually just packagers. Often, Fedora maintainers test features in the distro _before_ they are merged in upstream. For example, this Fedora version includes many nice KVM improvements, the utrace kernel patches needed for Systemtap userspace probing which are not upstream, the out-of-the-tree nouveau driver enabled by default... It's certainly more unstable than Ubuntu, but it's also more interesting for my taste. Also, using fedora I help to test and stabilize features that will go later into other distros.
Maybe nobody cares about Itanium and Sparc (well, some people cares about sparc, but they probably use opensolaris) and there are not enought volunteers to handle those arches with the same priority x86 has?
I don't know how it compares to dtrace (in this wiki it appears that they have feature parity for all the important stuff), but I can tell you that it works quite well and it's very complete and it's well documented. It really deserves the 1.0 version tag.
But in the kernel world very few people seems to use it, it seems that perf + static tracepoints have become the preferred tool for performance diagnostics.

gnash needs to write and maintain a javascript VM and many other things. This project does not.
Also, it could use some of the gnash actionscript libraries...
If you take a look here, you can compare both photographies. Note that the hair is the same...

Just check the feature matrix
3D features are not really supported, but except that, most of the basic things seem to be supported - KMS, KMS-based FB, suspend/resume, dual head/randr, 2D, video...
If so, how does it differ from RDP or NX?
It seems to be better
Graphic commands - processes and transmits 2D graphic commands
Video streaming - heuristically identifies video streams and transmits M-JPEG video streams
Image compression - offers verios compression algorithm that were built specifically for Spice, including QUIC (based on SFALIC), LZ, GLZ (history-based global dictionary), and auto (heuristic compression choice per image)
Hardware cursor - processes and transmits cursor-specific commands
Image, palette and cursor caching - manages client caches to reduce bandwidth requirements
Live migration - supports clients while migrating Spice servers to new hosts, thus avoiding interruptions
Windows drivers - Windows drivers for QXL display device and VDI-port
Multiple monitors
Client for Linux and Window - can be easily ported to additional platform platforms.
Two way audio - supports audio playback and captures; audio data stream is optionally compressed using CELT
Encryption - using OpenSSL
Two mouse modes - provides client (more user-friendly) and server (increased accuracy and fully synchronized) modes
Lip-sync - synchronizes video streams with audio clocks
Spice agent - running on the guest and performs tasks for the client
Duh. You can use instead a fb-based text console, so where is the problem?
And how is that related to KMS? KMS is about moving mode switching to kernel, which is neccesary even for the most modern 3D cards. And the memory manager that was implemented to make it possible is also neccesary to implement correctly a modern graphic stack.

Note that KSM also works for Xen.
KVM may not mean the death of XEN, but it has been a long time since it replaced it as the de-facto Linux virtualization system.
If ZFS is the main motivation to choose the OS, you should use Opensolaris regardless of what happens in FreeBSD.
As a European, I can tell you the EU is a joke, the EC is one of the few things in the Union that seem to work.
