Has it only been five years? Yes, it has only been five years. The site that has become synonymous with video on the web, the site that sparked so many delightful internet memes, turns five years old today. Whether it's the best line in video game history repeated a million times over, or the most beautiful piece of art ever created in human history (the lesser-known HD version, of course), YouTube has it all.

Google is set to announce Android 2.2 at the Google I/O event this week and one of the highly anticipated features will provide a big boost for performance and battery life. Originally the Dalvik virtual machine was implemented as an interpreter, but now a JIT compiler will be used. Already benchmarks show a roughly 6x improvement in numeric performance with the new JIT. While this will make Snapdragon-powered phones like the Nexus One seem even more responsive it will have the biggest impact on lower end phones using ARM11-based chipsets. It remains to be seen how many existing models will receive upgrades to 2.2.

The LLVM developers seem to be driven to replace all parts of the GCC toolchain and libraries with home-grown alternatives under BSD-style licenses. The latest addition to the project is libc++, an implementation of the C++ standard library which is faster and uses less memory than the GCC libstdc++. The developers also intend to support standard library debugging which is ABI compatible to the release version, which should help developers cut down on lengthy recompile-and-debug cycles. The project is still in an early state but it already implements 85% of the C++0x standard library. As with the rest of the LLVM project, the development of libc++ is being supported by Apple.

"I didn't plan to pick a fight with Steve Jobs last night. It just sort of happened: An iPad advertisement ticked me off; I sent the Apple CEO an angry email; he told me about 'freedom from porn'. The electronic debate proceeded from there." Says the man who used to use LSD. This man knows how to sell iPads to America: think of the children!

There's one complaint we here at OSNews get thrown in our faces quite often: what's up with the lack of, you know, operating system news on OSNews? Why so much mobile phone news? Why so much talk of H264, HTML5, and Flash? Where's the juicy news on tomorrow's operating systems? Since it's weekend, I might as well explain why things are the way they are. Hint: it has nothing to do with a lack of willingness.

"UDS is over! And in the customary wrap-up I stood up and told the audience what the Foundations team have been discussing all week. One of the items is almost certainly going to get a little bit of publicity. We are going to be doing the work to have btrfs as an installation option, and we have not ruled out making it the default. I do stress the emphasis of that statement, a number of things would have to be true for us to take that decision."
