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.
