I am a freelance Linux consultant by trade, a sysadmin by vocation and an Open Source developer by conviction. Welcome to my soapbox !

Laptop memory usage

A week ago I visited MediaMarkt looking for some money to spend (and in the same throw improve my own life). There was this amazing deal to buy 2x 1GB DDR2 laptop-memory for only 77€. Faster than my laptop needs, but it happens to work flawlessly.

I always felt that my laptop could use more memory since I have this bad habit to use Firefox tabs as permanent memory. If I stumble upon interesting information but have limited time to read it, I just open a new tab to continue surfing.

Call for participation on mksysb

Ask any AIX system administrator and they will tell you that Linux is not ready for the real work. Many reasons are given, but one of recurring technical reasons is that there is no mksysb for Linux.

mksysb on AIX is a tool to do an (online) backup of your system in order to do a bare metal restore. It produces a bootable medium (tape, image, DVD) that restores the system partitioning/LVM configuration and restores the original filesystems for disaster recovery.

I defeated Viagra

A month ago I reported my defeat in the Viagra showdown, but apparently nothing is set in stone because recently I defeated Viagra! Hah!

Next target is Arjan van de Ven :-)

CentOS at LinuxWorld Expo, Utrecht, NL

Coming wednesday (31 october) there is a CentOS presentation (in Dutch) at the LinuxWorld Expo in Utrecht, NL.

If you happen to be there, drop by to say hello :)

The Oracle Unbreakable Linux incompatibility

It was exciting when a year ago at LinuxWorld Expo London we heard a rumor that Oracle was going to support Red Hat Enterprise Linux. It was surprising to find out that this rumor was not entirely as well-intended and supportive as it sounded.

Instead of helping the community, Oracle was directly attacking Red Hat with its own product as if it was showing the world that Open Source has no value and that even Oracle could run away with Red Hat's crown jewels and customers. A hostile take-over attempt of Red Hat by Oracle.

mrepo: now with YOU (Yast Online Update) support

Yes! After a few weeks of wanting this I finally took the time to write it. With the help from Jo De Baer I wrote YOU (Yast Online Update) support for mrepo.

mrepo works with helper-tools for the actual downloading of updates or creation of metadata and so the real meat is inside the tool called youget.

Drupal as seen by its creator

Monday evening, had a hard time finding the location because I trusted my GPS. It told me there was no such street-number. In the end I parked my car to search for the venue by foot and surprisingly I was parked 2 meters from the runway. Doh!

When I entered it was apparent that I was under-dressed for the occasion. For an exciting and young project like Drupal, the attendants were mostly dressed in suits. (mental note: do some research next time).

How a presentation made a tool better...

The aim of doing a set of Dstat presentations was not just to promote Dstat, but also to hear people's impressions and ideas. And lots of ideas were shared and ended up in the TODO list.

But one of the questions that I did not quite understand initially, turned out to be an interesting and useful idea. And after the presentation we sat together to show how simple it was to bring an idea into practice.

T-DOSE 2007 is dead, long live T-DOSE 2008.

T-DOSE 2007 is over, and it was good. It could have been great if more people attended and I think the lesson for T-DOSE is that more advertising is needed. And maybe that will lead to more presentation tracks so that even more people are interested in coming.

But the organization was perfect, the location superb and the people the max. So next year you cannot miss out.

Thanks to everyone who made it happen.

T-DOSE in Eindhoven, NL

This weekend T-DOSE takes place in Eindhoven, NL. This will be my first T-DOSE, but I expect it to be much like FOSDEM and FrOSCon, although maybe smaller and less developer-oriented than FOSDEM and probably more English-oriented than FrOSCon.

RPM Packaging news: lockstat and http_replicator

One of the reasons why I wanted to start a blog is because I often stumble upon new and exciting tools. and sometimes I want to share some information or an opinion on it. So a blog seems a good way to ventilate (and archive) that knowledge. Much like offsite storage...

This week 2 interesting tools caught my attention.

Defeated by Viagra

I noticed this post on Linux Weekly News where Dave Jones is twice as effective as Viagra. So like any curious individual, I wanted to see how I would score against Viagra, and the results clearly show I have failed :-/

But at least I do better than Natalie Portman ;-)

CentOS in printed publications 2

I stand corrected. For some reason Amazon does not show excerpts when looking just for CentOS. And the list of books that match CentOS is incorrect. Now if I redo my search query using CentOS Linux the real search-inside-the-book mechanism starts to work. Maybe it requires at least 2 keywords?

The result is a shining 15 books that contain CentOS in one way or the other.

CentOS in printed publications


One of the ways to promote CentOS is to have CentOS appear in shops and libraries. Currently our local bookshop has a few titles about Fedora and RHEL, but they do not mention CentOS at all.

These books are real bibles containing more than 1000 pages. They go into details about everything, but they fail to mention the RHEL rebuild distributions like CentOS or Scientific Linux.

Something is going on here ?

Mistakes made when using Drupal as personal blog

Being fallible (not being the pope) I learned some things from my Drupal installation. Dries asked me to keep a list of things, and this is a record of what I still remember.

Beware though that this list is focused on using Drupal for a personal blog.

You do not need the Blog module !
If you just want a personal blog, you really don't. I consider this vital advise, especially because not using Blog seems counter-intuitive and because it is described as:

Blog: Enables keeping easily and regularly updated user web pages or blogs.
