A prerelease build of Flash Player 9 Update for the Linux platform is now available. Flash Player 9 Update for Linux currently does not include full-screen mode and complete SSL support (SSL support is currently available in the Linux Plugin but not the Linux Standalone Player). Full-screen mode and SSL support will be available in the final release. The current Linux build is 9.0.21.55.
Go get it!!!
My friend has an old Apple eMac PowerPC G4 running at 700 Mhz, which he acquired in 2000.
He tried Ubuntu Breezy 5.10 and Dapper Drake 6.06 but with no luck running it on Xserver/X.org: when he goes into X11 mode after the boot, the screeen is absolutely black. He can go to console clicking CTRL+F1.
Here is the solution of the problem:
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.bak
sudo mv xorg.conf /etc/X11/xorg.conf
sudo /etc/init.d/gdm restart
The fourth implementation of ext file system is pushed into 2.6.19 development tree.
Ext4 is backward compatible with Ext3, so systems without Ext4 support can mount Ext4 partitions.
The main new feature of Ext4 is the support of Extents:
An extent is a contiguous area of storage in a computer file system, reserved for a file. When starting to write to a file, a whole extent is allocated. When writing to the file again, possibly after doing other write operations, the data continues where the previous write left off. This reduces or eliminates file fragmentation.
From wikipedia
The Extents are disabled for default, to guarantee the backward compatibility.

Performance Gain of Factor 15 to 40
I knew the headline would draw your attention 
I’d love it (and you’d love us) if these numbers were for the entire application suite, but totally unspectacular they’re for the import of huge formula loaded MS-Excel documents into Calc, which is nice enough to be delighted anyway.. Down on the floor and back to the facts: when loading a quite big Excel document, I’m referring to 25 MB of size, more than 100 sheets, a million cells and hundredthousand formulas, formula cells unnecessarily broadcasted their initial recalculation state to all dependents. Building up this dirty tree took most of the time and by replacing it with a document wide simple chain mechanism for this case, loading times went down to a fraction. The metrics from two different machines for that document are:
Small one processor system: model name : Intel(R) Pentium(R) 4 CPU 1.80GHz cpu MHz : 1816.213 cache size : 256 KB bogomips : 3617.58 Mem free : 386488 kB (or somewhere near that) old performance : 39:08 minutes new performance : 2:37 minutes performance gain: factor 15 Two dual core processors system: model name : Dual Core AMD Opteron(tm) Processor 275 cpu MHz : 2194.038 cache size : 1024 KB bogomips : 4393.64 Mem free : 3388412 kB old performance : 27:58 minutes new performance : 0:43 minutes performance gain: factor 39
