Wed, 17 Apr 2013 10:16:31 GMT

Here is an example on how to obtain all-way near realtime file syncronization on a cluster of server nodes managed by Puppet. It uses the old-ish but very useful csync2 to track all files, combined with the excellent lsyncd to trigger synchronization based on inotify events.

Advantages :

Scalable read performance thanks to local storage being used

Sound over HDMI for nVidia ION with Fedora

Thu, 16 Feb 2012 11:18:33 GMT

I just battled for a few hours with a Zotac Zbox ID41, which is a nice MiniPC based on the Intel D525 dual core Atom CPU and the nVidia ION2 chipset. This particular one is used in a meeting room and runs Fedora 16 x86_64. Everything works fine with no special configuration, except sound over [...]

OpenERP on Red Hat Enterprise Linux 6

Wed, 28 Sep 2011 11:07:48 GMT

Here are some quick instructions to get OpenERP 6 up and running on RHEL6 (or any of its clones such as CentOS, Ascendos, etc.). It’s not meant to be a full howto, but might help in some cases.

OpenERP is still not included in Fedora nor EPEL as of writing this. Hopefully this will change soon, [...]

Nexus S Android update to 2.3.4

Wed, 4 May 2011 20:16:54 GMT

These are my quick notes after updating my Google Nexus S Android phone to the latest 2.3.4 release from this week. The main issue I had was that my phone was rooted, making the official update package fail with a “status 7″ error, because the existing system was modified.

Step one was to restore the original [...]

Firefox Sync with your own server

Wed, 6 Oct 2010 21:14:07 GMT

I’m now sharing browsing history, stored passwords and bookmarks between my work desktop computer, my home desktop computer and my laptop, thanks to the Firefox Sync add-on. The best part is that all of the shared data is encrypted directly at the web browser level and stored on my own dedicated server using https. You [...]

RHEL6 (Beta) minimal installation

Fri, 30 Apr 2010 18:16:01 GMT

I’ve just started testing the Red Hat Enterprise Linux 6 Beta, and I was really happy to see that the Minimal installation option is back at last. I know it’s always been possible to achieve something similar with RHEL5 and kickstart, or even something close enough by choosing to not install anything except the Base [...]

Apple iPod Nano 5th generation and Fedora GNU/Linux

Fri, 30 Apr 2010 18:16:01 GMT

I just got my first Apple iPod. Yes, me with an iPod. Don’t ask. It’s the latest Nano, the 5th generation, available since late 2009. It’s tiny, yet it packs 8GB of flash memory, a camera (for video only, not photo…), a microphone, an accelerometer, a relatively big screen, a radio… even a speaker.

I really [...]

Linksys WAG160N vs. D-Link DSL-2740R

Fri, 30 Apr 2010 18:16:01 GMT

I was having problems with my home DSL gateway device a few months ago. It was an old-ish Netgear device which had been running fine for years. Since it supported only wireless A/B/G, I decided it was a good time to replace it for a wireless (draft) N compatible device as my latest laptop supported [...]

FreeNX headache

Fri, 30 Apr 2010 18:16:01 GMT

I’ve just wasted a couple of hours trying to get a FreeNX server working, but just kept getting this error : Cannot establish any listening sockets - Make sure an X server isn't already running Not very explicit, not very useful, and searching returns many results about people having the same problem. The solution is simple, though [...]

GNOME menu entry for Xine DVD playback

Fri, 30 Apr 2010 18:16:01 GMT

Most GNU/Linux distributions include the proper mime types to be handled by Xine when it is installed, but not for DVD Video ISO images on disk. But it’s really easy to add.

If the DVD button in Xine work for real Video DVDs, then just create the /usr/share/applications/xine-open-iso.desktop file with the following content, and you’ll now [...]
