SUSE STUDIO is totally coool, I tell you….. =)

you can make your customized LINUX CD/DVD and share with others….

Here is the link to one of the disks I created…

Built with SUSE Studio

FEATURES:

————–

Linux kernel 2.6.27 (32 bit)

KDE 3.5.10 base

Konqueror

K3b

Kate

Kdebluetooth

KNetworkmanager

VLC 1.0.1

SMplayer

gparted

wine.

All this in an ISO of just 423 MB…. ENJOY !!!

p.s. By any chance, if the link is broken, just let me know…

Linux kernel bits which I feel excited about…

Here are some  comparisions between:

Linux (2.6.23) versus Windows (Server 2008)…

I compiled these here so that, next time if I want to check the scheduler latency of linux kernel, I should not go for googling. 🙂
