OpenPGP key transition to 4096-bit RSA keys

For a number of reasons, I’ve recently set up new OpenPGP keys, and will be transitioning away from my old one. I use Thunderbird and the Enigmail OpenPGP extension to encrypt and sign my email communications. Check out the Security in a Box documentation if you wish to do the same.

You can read the full statement of transition from this archive which includes details about old/new keys, signatures etc. My personal OpenPGP key has been updated in the contact page. I’ve also advertised this change on social networks I use frequently.

If you haven’t done so, I recommended checking out the Riseup OpenPGP best practices documentation.

1 « en maintenance » suite à une brèche de sécurité

Si vous aviez un compte sur, cette annonce vous concerne:

(traduit de Ubuntu Forums is down for maintenance)

Ubuntu Forums est en maintenance

Il y a eu une violation de la sécurité sur les forums Ubuntu. L’équipe de services informatiques de Canonical travaille fort en ce moment pour rétablir un fonctionnement normal. Cette page sera mise à jour régulièrement des rapports d’étape.
Ce que nous savons:

  • Malheureusement, les attaquants ont obtenu l’identifiant de chaque utilisateur local, mot de passe et adresse email à partir de la base de données des forums Ubuntu.
  • Les mots de passe ne sont pas stockés en texte clair. Toutefois, si vous utilisiez le même mot de passe que sur Ubuntu Forums sur d’autres services (tels que le courriel), vous êtes fortement encouragé à changer le mot de passe sur l’autre service au plus vite.
  • Ubuntu One, Launchpad et d’autres services Ubuntu / Canonical ne sont pas affectées.

Pairing the Logitech Performance MX (and others) to the Unifying Receiver in GNU/Linux

Back in 2009 Logitech introduced the Unifying Receiver, a great way to connect multiple wireless mice and keyboards to one single RF receiver on your PC.

The Unifying receiver is uniquely paired to your mice and keyboard. When you buy your devices, they are already paired to the accompanying receiver. They work out of the box on any GNU/Linux system.

However, if you loose the original receiver, and get another one for free from Logitech under warranty, or if you want to pair / unpair new or existing devices, you will need to pair them again. This used to be only possible using Windows. Not anymore. 🙂

Solaar is a GNU/Linux device manager for Logitech’s Unifying Receiver peripherals. It is able to pair/unpair devices to the receiver, and for most devices read battery status.

It comes in two flavors, command-line and GUI. Both are able to list the devices paired to a Unifying Receiver, show detailed info for each device, and also pair/unpair supported devices with the receiver.

I tested this in Debian 7 for which there are packages and a repository, and there is also a PPA available for Ubuntu, which also works in Trisquel 6. Here are some screenshots:





Wow, it’s been quite some time I hadn’t seen such attention to detail in an application apparently destined to such a « simple » task.

Buttons mapping

Solaar doesn’t take care of the buttons mapping (yet?), but I thought I’d throw this extra here. Some time ago I went through the trouble of identifying all the buttons on my mouse and documenting (from Logitech’s accompanying manual) the various expected functions as present in Windows.

This is useful for applications where you can specify which button is assigned to an action. Enjoy!


  • Button 1 – left click
  • Button 2 – wheel click / middle button
  • Button 3 – right click
  • Button 4 – wheel forward
  • Button 5 – wheel back
  • Button 6 – wheel left click
  • Button 7 – wheel right click
  • Button 8 – browser history: forward
  • Button 9 – browser history: back
  • Button 10 – application switch / Exposé on Mac
  • Button 13 – zoom

Debian Quebec is here :)

As many of you already know by now, Debian 7 is here!

I’ve been using Debian as my primary work environment for a few months now and Trisquel at home for the past year and a half or so. My advocacy work has changed as a result, and I stopped focusing on Ubuntu, while still recommending version 12.04 LTS that just works for many. There’s also Ubuntu Gnome (or is it Gnome Ubuntu) now, so there is still a good array of choices for those like me that like the GNOME 3 environment and find it productive. Oh, did I mention Cinnamon 1.8 was just released?


I am happy to announce that there is now a Debian Quebec group, and we just got our mailing list approved in the Debian project. This was not as fast an easy as in Ubuntu-land, and I took the time to fully document the process to get the mailing list going, in case others may want to do the same. It may all seem too slow or difficult, but every step of the way several people helped and I learned a lot. I took this as an opportunity to contribute to the project and at the same time I found that it may be hard for new GNU/Linux users to get started in Debian – or even for experienced ones like me, coming from Ubuntu.

That’s why after a few IRC messages I started working on a Welcome to Debian resource (and team) aimed at people that use other distributions and come to Debian for the first time. It’s still very new and incomplete, but it’s what I wished was around when I started dedicating serious time to this distribution a few months ago.

As luck would have it, Debian 7 was just around the corner, just a few days/weeks after Ubuntu 13.04 and Trisquel 6 were released. This called for an all-distributions Debian 7 release party (we’ll have two locations, Montreal and Quebec City). There will be workshops and presentations from 12:30 to 5:30 PM and then a happy hour with CLibre and Libre Planet. Check the Agenda du Libre if you’re in Montreal this week (or any time soon), perhaps we can cross paths.


New LibrePlanet LiveCode users group

I’ve recently been involved in a project with a customer to set up their development team to use LiveCode on Debian workstations. If you haven’t heard about LiveCode, they recently had 3,342 backers pledge £493,795 of the initial £350,000 goal on Kickstarter. That’s quite an accomplishment! I am not involved in the development part of this project, only in providing infrastructure support and services.

Since we needed to start working on documentation and I already work with other colleagues via IRC, I thought it would be useful to start a wiki space and IRC channel, and other resources via the dedicated resources provided by the Free Software Foundation in addition to upcoming resources that may be provided by RunRev, the creators of LiveCode.

The goal here is to collaborate with the community and help RunRev in this initial transition to open sourcing LiveCode, while offloading some of the self support to the FSF infrastructure (via LibrePlanet which is their community portal/resource).

If anyone is interested, a few initial resources and links have been put together already.

It looks like many people are already using LiveCode on Ubuntu, judging by the many screenshots in existing tutorials and guides. I hope other Debian derivatives benefit from this and perhaps even other distributions.
