Using time zone dumper utility (zdump) like this:
zdump -v /etc/localtime | grep 2007
we can see that:
/etc/localtime Sun Mar 25 00:59:59 2007 UTC = Sun Mar 25 01:59:59 2007 CET isdst=0 gmtoff=3600
/etc/localtime Sun Mar 25 01:00:00 2007 UTC = Sun Mar 25 03:00:00 2007 CEST isdst=1 gmtoff=7200
/etc/localtime Sun Oct 28 00:59:59 2007 UTC = Sun Oct 28 02:59:59 2007 CEST isdst=1 gmtoff=7200
/etc/localtime Sun Oct 28 01:00:00 2007 UTC = Sun Oct 28 02:00:00 2007 CET isdst=0 gmtoff=3600
Use the following procedure to extract contents of an RPM package:
rpm2cpio package.rpm | cpio -dimv
As the name implies, rpm2cpio takes an RPM package file and converts it to a cpio archive. The -i flag to the cpio command indicates that cpio is reading in the archive to extract files, and the -d flag tells cpio to construct directories as necessary. The -v flag tells cpio to list file names as files are extracted, and the -m flag tells cpio to retain previous file modification times when creating files.

[img_assist|nid=805|title=|desc=|link=none|align=left|width=125|height=188]Written by a leading developer and maintainer of the Linux kernel, Greg Kroah-Hartman, Linux Kernel in a Nutshell is a comprehensive overview of kernel configuration and building, a critical task for Linux users and administrators.
The upcoming 2.6.20 Linux kernel is bringing a nice virtualization framework for all virtualization fans out there. It's called KVM, short for Kernel-based Virtual Machine. Not only is it user-friendly, but also of high performance and very stable, even though it's not yet officialy released. This article tries to explain how it all works, in theory and practice, together with some simple benchmarks.
Virtualization is a hot topic these days. With hardware getting more and more capable, by means of cheap multi-core processors and gobs of memory, we can expect virtualization to become only more important in the coming years. Virtualization promises reduced costs for IT organizations, both hard (machines, power, cooling) and soft (admin and operations personnel).
Seeing that the development of the ext3 file system successor has started, and that Andrew Morton has released mm patch containing ext4 file system, I decided to run some simple benchmarks, even in this early stage of development.
The other day I was playing with fun Google Trends tool and got an idea to check Ubuntu versus Debian popularity. You can see the result on the picture below and I don't know about you, but it simply amazes me how popular Ubuntu is these days. And not only that, but its popularity is growing day by day, while it can be easily seen that Debian is either stagnating or slowly fading out.
