I must confess: I’ve almost never used Google Reader as I’ve only been using Akregator as far as I remember. I didn’t want to rely on anyone to host my feeds and I guess I needed Google to stop providing Google Reader for free to realize I could just host my own web based reader, like many will probably do from now on.

I needed a way to synchronize my bookmarks in Firefox across three computers, and doing it manually wasn’t an option anymore, so I turned to sync-like extensions. I needed something which would give me full control on the data storage part (I don’t want to use their servers). The first one I tried was Xmarks, which just can’t handle the 4MB bookmarks I have, so that was a dead end. Then I realized you can host your own Firefox Sync Server and that’s how I did it.

This blog now has interactive comments thanks to the Wt Comments project started by my friend Martin Peres. On his blog, you’ll find all the reasons that make Wt Comments a must have for us users of static blogs. However, they’re still a few features missing:

• Allowing users to delete their comments;
• Allowing users to subscribe/unsubscribe to an article in order to receive mails for new comments.

Feel free to comment(!), request features or, even better, send patches to improve it!

Martin Peres and I made a quite long talk about the X.org security at XDC 2012 in Nuremberg.

Michael Kerrisk made a really good article for LWN.

The slides and the video are available for download. The YouTube hosted video is embedded below. There is also a short summary written by an XDC attendee.

Wayland and Weston have been moved to community/extra! Thus this How to is no longer necessary. I’m just keeping it here for reference. I may update *-git packages but I can’t promise I will do it frequently.

Powertop 2.0 is out (Release Announcement, The H Open article).

So how do I use it ? Well, I found the html report to be the most useful as it gives you the exact commands (Tunables) you need to run to adjust power settings:

1

sudo powertop --html

You will then find those commands in the Tunables tab in the powertop-*.html generated file. You should try carefully each one of them one by one as they can have some nasty effect (disabling USB mouse, increasing power consumption…).

If you’re using systemd like I do, and want to use the classic /etc/rc.local file to set those settings at boot time, you should use the initscripts-systemd package and make sure it is enabled with :

1

sudo systemctl enable rc-local.service

I recently had to setup cgit with nginx on Arch Linux for http://git.siosm.fr and it took me quite some time as I was not familiar with cgi, fcgi, fcgiwrap, spawn-fcgi and had no idea how they worked together.

Here is a list of all the thing you should read while installing Arch Linux if you ran into troubles. This post will be updated as often as possible. If you find something inaccurate, feel free to contact me!

I just received my Nokia N9 and I’m starting to learn Qt Quick/QML to design some applications for it. You can find some useful applications on websites such as N9 Apps and Apps for MeeGo but there’s still a lot of features missing. Update expected soon as I’ll share my findings on how to build apps, witch SDK to use and stuff like that.

To build KDE on Arch Linux with the nice kdesrc-build script, you need the packages listed on this page: KDE TechBase plus this package: perl-libwww. I didn’t have to rebuild Qt as the version provided in Arch Linux repository seems to be OK.
