Updating a ZFS Mirror
A few days ago, while I was on the phone, my machine experienced a kernel panic. The backtrace pointed a problem somewhere in the swap management code. I was on a hurry at that time and rebooted the machine without taking the time dig in the problem deeper.
On the next day, I eventually realised that an hard disk was logically missing on the system and the ZFS mirror it was belonging to was working in a degraded mode. This disk holding a swap partition, the panic quite makes sense: some data was stored there and could not be paged-out anymore.

the pool to continue functioning in a degraded state.

Thomson ST2030 Feature Key Sheet Template
Technicolor's (ex. Thomson's) ST2030 SIP phone features 10 feature keys that can be used as fast call keys to reach a configured number by a single key-press.

Location of Feature Keys on the ST2030.
I finally decided to configure these keys with proper numbers instead of browsing my directory each time I want to make a call. But the phone only ships with a single paper sheet to hand-write the names corresponding to the configured numbers and my hand-writing is somewhat like what would produce a drunk cow with Creutzfeldt–Jakob disease. I browsed the Internet for a sheet template to fill-in, print and cut, but was unable to find some.
I'm on the Radio
Earlier this year, 4 friends and I joined together with the goal of having our very own radio show. The first show was recorded in late November and was on air in the beginning of October. From that date, every two week, a new issue is broadcasted live on Radio Campus Clermont-Ferrand.
The show is called Les
aventures du comte de Malamanteau
(French for
Earl Malamanteau's Adventures), and is mostly music
centered: during one hour, a selection of music from a given
country (a different one for each issue) is aired. So far,
we have visited South Africa, Kenya, Tunisia, Lebanon,
Ukraine and Finland.
A website has been setup for listeners to have access to broadcasted shows and gathering more information about the music we chose and location we visited: malamanteau.fr.
TeXLive 2011 on FreeBSD
A few weeks ago, I updated the freebsd-texlive project to make TeXLive 2011 (the latest verison) available as ports for FreeBSD.
In order to help users who don't want to install the whole TeXLive collection (~2000 ports), a basic script has been developed to ease-up finding which port provides some file required by a given package.
As usual, feedback is welcomed!
Additional note for a proper shebang
I recently encountered a shell script lacking some functionality I wanted to rely on, and started editing it to provide a patch for the author.
The first line of the script was:
#!/bin/bash -x
Those who know me might imagine how my eyes were bleeding (the other may want to read my previous entry about writing portable shebang for shell scripts), but this shows another problem one may encounter when porting a shell script with an invalid shebang.
Typesetting Korean with TeXLive
Today, I received a request for adding support for ko.teX to the FreeBSD TeXLive ports. I created 3 ports for this purpose: print/kotex-util, print/kotex-macros and kotex-fonts-all.
I did some basic testing locally, but I don't read Korean, thus I could not test beyond the (minimalistic) examples. I am therefore looking for FreeBSD TeXLive users who are able to write Korean to help testing this package. If you are one of them, please give it a try and report any success or failures on the issue page.
TeXLive 2010 on FreeBSD
I definitively have a lack of time at the moment. Since this blog last entry is about Hey guys, I have just pushed TeXLive 2009 in the freebsd-texlive project
, I guess I have to take the time to write this short post:
One month ago, I pushed TeXLive 2010 to the freebsd-texlive repository. Moreover, because portshaker is now in the FreeBSD ports tree, installing bleeding-edge TeXLive on FreeBSD has never been so easy!
TeXLive 2009 on FreeBSD
I recently updated the freebsd-texlive project to make TeXLive 2009 (the latest verison) available as ports for FreeBSD.
I used a script for update TeXLive 2008 on a regular basis, but since these new ports feature pkg-plist files, I had to setup an update jail. So updates for FreeBSD TeXLive ports will be generated daily at 5:30 CET.
gpg: OpenPGP card not available: IPC write error
If you reach this page searching the internet for this error and did not find anything usefull, it might be because the error you want to search is actually Unknown IPC command

ZFS: unsupported ZFS version 14 (should be 13)
After updating to the latest development version of GNOME thanks' to MarcusCom ports I wanted to log out and back in but X refused to restart because of the in-heavy-development Nouveau video driver. I run in this problem every once a while and a full reboot solve this problem. However, the system did not boot.
