I finally decided to request full BGP tables from all of my ISPs, so I can easily change the preferred path to certain destinations.
However this meant that now I have to monitor both the state of the BGP sessions, but also the amount of routes that I receive from my neighbors.
Before my days with full [...]
Since I’m a long user of Xchat I decided to upgrade it and found that it does not compile with the recent glib library.
The problem is that the new versions of the glib library introduced one limitation for includes. Now you only have to include glib.h and every more specific inclusion breaks the builds.
Even thou [...]
Very often I login on machines with older mii-tool that reports 1Gbit/s cards as if they are connected on 100Mbit/s. This is normal as mii-tool is depricated. But a lot of old timers like me are used to its output. So I wrote a very simple awk script which can convert the ethtool output to [...]
Recently I wanted to check if I have reached the limit of my network connection. However I constatly had to login on my router and check the traffic on each interface… and I had to watch it continiously.
.
So I decided that I’ll write a tool which will collect the information and regulary update a DB, [...]
Today I decided to join my co-located server to pool.ntp.org.
It was surprisingly easy and now I have my machine contributing to the big effort that is pool.ntp.org.
Statistics for it can be found here: http://www.pool.ntp.org/user/hackman
Since I started using Linux::Unshare after I created my Linux::Setns I found that unshare was missing a few tests.
I added them and sent a patch to the current maintainer Boris Sukholitko. However a few days later he wrote to me that he is no longer maintaining the module and proposed that I should take over [...]
I’m preparing a talk for YAPC::EU. The talk will be about managing Linux containers in Perl and for doing that I needed some functionality that was currently missing
So I created a new Perl Module - Linux::Setns.
This is my first attempt at building and supporting modules on CPAN… but I hope I’ll add a few [...]

I needed an easy way to download videos I streamed to Twitch.tv, so I created this small script which downloads all parts of the video, converts them to mpegts and then combines them into a single mpeg flv video, ready for upload to YouTube.
#!/bin/bash
video_dir=~/twitch
if [ $# -ne 1 ]; then
