A markdown based wiki about Linux, Open Source, VoIP and other geeky stuff.

What I'm up to today

For those who have known me for a couple of years now, you've learned that I was really into Linux, Postfix, OpenVPN and Asterisk for some time, back when I was managing 5 Linux servers or so.

As of today, I manage about 300. I spend a lot of time automating, centralizing and orchestrating management with some of those tools:

In the same vein of automation at a personal level, I'm a huge fan of Automagic on Android, and Alfred on Mac, and hackable connected objects like WeMo devices.

My work environnement is based on Fedora with i3 tiling window manager, running as a KVM on a libvirt RHEL7 host. I'm a die-hard shortcut keyboard user.

I talked about SaltStack at Jeudis du Libre conference. Check my Github for the decks.

Why a wiki?

Story time. I started this website in June 2005 (but bought the domain in March of the same year). The idea was to save whatever I was finding so I could look it up later if I needed again. I figured that I would put those notes online so it would probably be helpful to other people.

It all started as a self-hosted Wordpress blog as (changed to around September 2011). I had a lot of times on my hands and I was able to interact with my readers. On the busiest months I was getting 20000 visits a month. After a while, spam and security issues became problematic, and the maintenance became a burden (files and database backup, PHP and security upgrades, etc.). As a result, I became kind of bored of maintaining it or even publishing anything.

Today, my focus has changed. I want to publish things quickly. From anywhere in the world, I want to be able to write, connected or not, and as soon as I connect, the content gets published.

So here we are, almost exactly 10 years later, I moved from a blog to a wiki platform in July 2015. The content is still there and I hope you find useful stuff.

This site has gone through four design revisions: 2005, 2008, 2011 and 2015.

Why Markdown?

I write articles on my personal computer, a MacBook.

Markdown is great because every articles of this site are stored on disk. It is plain text, so Alfred/Spotlight indexes the content, and I can just look up a word and I will get to the article source immediately. I can grep, sed, awk the hell out of them and bring correction very quickly.

It is also very easy to publish automatically.

My workflow comes as follow:

  • I edit articles locally with Visual Studio Code (yes, it is an open source Microsoft product)
  • I commit changes to my GitHub
  • I trigger a "git pull" on my VPS from an Alfred workflow
  • Article is online

Can't find anything here?

There is no content search engine on this platform. Try this kind of query instead, it should point you to the right page.

About me

I like building simple, powerful, resilient, secure and automated infrastructures. Preferably based on open tools and protocols. Privacy is a main concern.

When I'm not busy at a computer, I travel, hike, camp out and take photos.

I'm an INTJ: INTJs are known as the "Systems Builders" of the types, perhaps in part because they possess the unusual trait of combining imagination and reliability. ~ Marina Margaret Heiss

I work in Brussels, Belgium.
