Gummen, gummen en nog eens gummen!

Dat was het! Maandag 6 september ben ik met een maatje naar het circuit van Zolder (België) geweest. De weergoden waren ons zeer gunstig gezind. Nieuw setje banden door Gilbert (Wing Palace) erop laten leggen en dat was super top……. en nu ook bijna op ;-) Want gummen, dat is wat we hebben gedaan.

In plaats van standaard straatbanden heb ik nu een setje race-banden erop laten leggen. Race attack bandjes. Op het circuit is de bandenspanning achter teruggebracht naar 1.8 Bar en voor 2.0 Bar. Het was die dag om en daar bij 24 graden dus prima weer om je uit te leven.

Met mijn maat deden we training niveau 2. Je rijdt dan in kleine groepjes met een marshal achter je voorzien van camera. Hij neemt op hoe je rijdt. Later in de theorie sessies wordt stilgestaan waar je bijv. je bochtensnelheid kunt verhogen door bijvoorbeeld de bocht beter aan te snijden, later te remmen, dichter bij de apex te komen, etcetera.

Uiteindelijk heb ik naar schatting rondjes gereden van rond de 1:51 min. Niet slecht, niet slecht….

Kortom, het was een superdag! Sinterklaas maar vragen voor een nieuw setje banden en knee pads………

In this post I will describe some useful scripts that I’m using for administrating Linux servers.

Basically I’m using caspar – apt-get install caspar caspar-doc – for maintaining my server park. Great tool, do have a look. Next to that I use some various scripts for for checking the health of the individual servers and nodes.

This first script gives some insight on disk space used and works on regular partitions and also on lvm volumes. You can change the value [ $usep -ge 80 ] to something you find useful. And also you can mail an alert if used space is over the value you specified.

Conky 1.6.1 on Hardy Heron

Conky 1.6.1 on Hardy Heron

update: also works on Intrepid Ibex!

Step by step howto install Conky 1.6.1 on Ubuntu Hardy Heron.

Conky is a system monitor for X originally based on the torsmo code. Since its original conception, Conky has changed a fair bit from its predecessor. Conky can display just about anything, either on your root desktop or in its own window. Conky has many built-in objects, as well as the ability to execute programs and scripts, then display the output from stdout.

For more information about conky, visit http://conky.sourceforge.net/

Currently in the Hardy repository there is version 1.5.1 available. However, this version does have some issues and there are a lot of fixes between 1.5.1 and 1.6.1.

So I decided to install the latest version from source. Lateron I will describe howto create an deb file from source.

The need for speed! Everyone who uses ConsoleOne for Windows knows that it’s a pain in the ass referring to speed. So, let’s see if it gets better under a linux workstation. I’m using Ubuntu Heron but debian should work as well.

Just follow these simple steps and you have ConsoleOne up and running in no_time.

[update apr 2009]:
also works on Debian Lenny. Eric Gerlach mentions the following : If you’re running the amd64 port of Debian or Ubuntu, you have to install ia32-libs and ia32-libs-gtk for the installer to work.

[update dec 2008]: also works on Intrepid Ibex!

Recently I reinstalled my computer at work and missed my Oracle Calendar. Here is a small howto to setup the calendar client.

Download the latest client from the Oracle website. Currently client version is cal_linux_1012.tar.gz (39,732,486 bytes)

Extract the client…

  1. tar xvzf cal_linux_1012.tar.gz

After extraction you find a directory OracleCalendar_inst/ go there and do the following..

Mediawiki Farm – Administer multiple wiki environments

2009/07/28 Update: I’m working on a robust version that handles the diversity of mediawiki’s databases. Therefore the script should work with newer versions of mediawiki.
2008/06/19 Update: Added entry, howto setup VirtualHosts / CNAME
2008/04/28 : version 0.4 is available.

Overview

As we all know, wiki’s are hot. And at the University we’ve got request constantly for facilitating them. BUT, there’s also a big issue and that is the fact that there isn’t any easy administration tool for installing and archiving wiki’s. So, with that in mind I started to work on a solution to administer multiple wiki’s, in this case mediawiki’s.

So, what does it need to do

Well basically, I just want to run a command line script that creates a wiki-directory linked to the source directory for easy updating and create a wiki database and user.

If this is what you want….. then read on

Ubuntu on Dell XPS M1330

Latest update: 4 aug 2008

For recapping my findings, I wrote up a small article on how to install Linux Ubuntu 8.04 LTS Desktop Edition (32bit) on a Dell XPS M1330.

Goals:
I switch from 64bit back to 32bit for compatibility reasons. There are to many apps that don’t work and are required to fit my needs. So I set up a boot partition (350MB – unencrypted) and a encrypted partition (100GB). Then I used that partition to set up LVM2 and prepared a root (10 GB), home (86 GB) and a swap partition (4 GB).

Download @ www.ubuntu.com and make sure to check “alternate cd” checkbox. It gives you the opportunity to install lvm2 on a encrypted partition.

Intro: Normally I run OSX os on Macbook Pro’s. However, since these are very pricey, and I smashed mine to smithereens,  I’ve decided to buy a cheap Dell.

  • Hardware
  • Partitioning harddisk (Dual boot: Ubuntu & OSX)
  • Installing OSX
  • Installing Ubuntu

Howto install vpn on Asus eee pc series

For a colleague of mine at the University of Tilburg (Netherlands) I connected his new gadget to the internet. He wrote the following on his webblog

[communitysense.wordpress.com]

I have to work a lot on Tilburg University campus, and continuously need to access the Internet, which is one main reason I bought my ASUS EEE laptop. However, to get access on campus one needs a VPN connection. On Windows machines, it is no problem to install the Cisco VPN client, but, alas, not so for Linux machines like mine. Raymond Mul, ICT manager at the Faculty of Law, and avid Linux enthusiast, has been so kind to write a short manual (in Dutch) explaining how to make the university network open up for Linux lovers as well.

Download asus-3e-uvt-vpn.pdf Version 0.1

If you find this howto useful, please leave a note. If the Dutch characters look scary to you, purchase me to write this howto in English. ;o)
