### Suse 11 with KDE4

I was very disappointed by KDE 4.0 when I first tried it on an ubuntu machine. It was just unusable. I would not have even considered it as a beta.

I changed the system on my home laptop because Ubuntu with KDE 4 was there. I decided to go for something more roots. I had good memories of Gentoo when I tried it some years ago. Maybe I just became too old to appreciate it anymore. But after spending several hours on a Grub error 2 problem, seeing the live CD does not even use grub so you can't use the CD to boot from hard drive and fix the problem easily, wondering if the problem was a problematic Grub version with my drive or not (I never had problems with Grub and other distros on that same machine before), I decided to install OpenSuse 11.

I was surprised (and impressed by Suse) that KDE 4.xx shipped with OpenSuse was usable! Except the program menu, it's not worse than KDE 3.

### Linus vs OpenBSD

Today's popular story is Linus Torvalds message to OpenBSD where he writes:
I think the OpenBSD crowd is a bunch of masturbating monkeys
Beside that provoking sentence he has a valid point. Security bugs should not be more important than other bugs. Too often, management and psychology encourage making security bugs a very important issue and security people VIPs. I have seen this over and over.

### Java Compilation Performance / Processor Speed

I just found out my laptop was faster in default settings than my home desktop to compile a resonably sized project (5 min vs 6 min). I was surprised as I thought the disk in the desktop would make a big difference. The processor in my desktop is not that great (simple pentium e2180). My laptop has a 2ghz core2duo processor. In Ghz processor are of the same speed.

I tried to overclock my home pc to see what difference it could make, I made it run at 2.6Ghz instead of the standard 2Ghz. The compilation time dropped to 4.5 min.

The ration of processor speed (2.6/2) is almost the same as the ratio of compilation time (6/4.5). I am surprised by such a linearity of behavior.
