Sat, 27 Mar 2010 22:57:10 +0000

Using the perl that comes with your distribution is usually fine, but it has some limitations. When building a perl for a distribution it needs to be versatile and fit various needs.

Dual-Screen setup with Xorg, RandR1.2 and ATI 9.2 (v8.528) Linux x86_64 drivers

Sun, 22 Feb 2009 21:25:22 +0000

After seeing that ATI has released again drivers for Linux with a new major version number (and not the scarry .0 behind it) I thought it was time to battle the ATI dragons again. As Debian usually lags behind on the proprietary ATI stuff (who wonders…) I’m using aain the binary packages provided by ATI.

System backup vs. system images

Fri, 13 Oct 2006 19:34:11 +0000

Creating a system image is IMHO different from creating a level 0 backup.

A backup is destined for the one host it was taken from, no other. MBR, partitioning, filesystems will all stay the same. Whereas a system image is used to multiply an installation to different hosts, with probably different partitioning, eventually different mount points. Differences of configuration is not part of this post, so yes, there are definitly different setting for network, hostname, …, but that has to be handled after restoring the image.

Thu, 03 Nov 2005 09:16:58 +0000

Strange, but true. Our new server got hacked recently by some unknown folks. The downside of this incident was, that we had visitors from some unethnical hacking groups, which abused the server for UDP attacks and spam mailing. I cleared the remaining 18000+ mails in the deferred mail queue yesterday.

vServer move to fx7.org

Tue, 18 Oct 2005 21:40:57 +0000

As always it seemed to be just a view hours work to move all services from the old mos.at hosted vserver to the new dedicated server owned by Duke. So we join efforts on that front and are going to share the server for all our vhosts and services.

WordPress setup

Fri, 05 Aug 2005 20:12:30 +0000

After some time, mambo was a little too complex for my needs, so i decided to try wordpress.

There are also tons of plugins available, and although not as easy to administer (still fine), it offers everything I need and is very fast compared to mambo (because it’s simpler).
