Development projectsNews and EditorialsParrot 0.0.4 is ReleasedUse Perl reports on the release of Version 0.0.4 of the Parrot compiler, which is at the heart of the new Perl 6 language. We now have a working JIT compiler, thanks primarily to Daniel Grunblatt. Gregor Purdy produced something he calls 'predereferencing', which rearranges Parrot bytecode in memory to give a 22% speedup over the normal Parrot run. Dan Sugalski himself has provided a fast arena-based memory allocation system, and a copying garbage collector to match. We're starting to look like a real interpreter, and to prove it, Clinton Pierce has written an XML parser in Parrot bytecode. Also included in Parrot 0.0.4 is Alex Gough's bignum library, code cleanup by Jason Gloudon, and "rudimentary regular expression support" contributed by Brent Dax. Here is the full list of changes for the new Parrot. The latest version of Parrot may be downloaded here. See the Parrot 0.0.4 readme file for the necessary build instructions. Additionally, Simon Cozens has handed off the duties of Parrot project leader, or "Parrot Pumpking" to Jeff Goff. ElectronicsNew Icarus Verilog simulator (gEDA).

"In this whitepaper on Linux Scheduler Latency, Clark Williams of Red Hat Inc. compares the performance of two popular ways to improve kernel Linux preemption latency -- the preemption patch pioneered by MontaVista and the low-latency patch pioneered by Ingo Molnar -- and discovers that the best approach might be a combination of both." Opening Up the PlayStation 2 with Linux (O'Reilly). Howard Wen reviews the Sony PlayStation 2 Linux development environment on O'Reilly.

It's true that we have all kinds of nifty desktops and applications. This is great. It is also, sadly, true that as the capacity of hardware has increased -- bigger drives, more memory, faster processors, an actual reduction in price -- coding has fallen slack. We do just about the same stuff at just about the same speed, even though our machines should, if the coding standard of even two or three years ago were in place, literally scream with speed."

Never seen anything like it (except maybe Lynx) in the main browsers - even long pages in my Most Often Visited list all but instantly popped into place. The rest of KDE 3 is simply spectacular, too. Everything is snappier, from menus (despite the addition of cool menu icons) and dialogs (these pop up much faster) to applications, and the look is even more professional than KDE 2.
