Lenteurs sur FireFox 3.5
Je fais partie des premiers utilisateurs de FireFox, a la vieille epoque ou celui-ci se nommait Phoenix ou FireBird. J’ai rarement eu a me plaindre, sauf lorsque j’ai installe la derniere version 3.5.
En effet, FireFox “freezait” et connaissait beaucoup de ralentissements, sur de simples pages HTML toutes basiques. Apres avoir parcouru les forums, il s’avere que deux solutions existent:
- la plus propre, mais longue: creer un nouveau profile.
- dans les options, desactiver Java.
J’ai tente la premiere, le navigateur “a vide” carbure, mais apres avoir perdu toutes mes configs personnelles j’ai prefere tenter la seconde. La browser va beaucoup mieux, mais en toute honnetete ca reste un peu lent par rapport a FireFox 3.1.

How to launch a single Unit Test with Maven 2?
Use this:

(unlike with Maven 1, you do not need specify the complete package name!)
Automatic update with TortoiseSVN
On my current position, I had to update my project with Subversion every morning. It took half an hour every day ; some other guys prefered to update only once a week or twice a month… But they accepted to spend half a day for merges etc.
Yet, I found a way to make this update automatically, thanks to a planned task in Windows XP.
The command that is launched is
"C:\Program Files\TortoiseSVN\bin\TortoiseProc.exe" /command:update /path:"C:\the\path\of\my\project" /notempfile /closeonend
Thanks to another planned task, I rebuild the complete project with Maven. And on breakfast I find my project up-to-date with all jars compiled and available.
Comment supprimer tous les accents, cedilles, etc. d’un texte en francais sous Unix?
Il suffit de lancer la commande suivante, en passant eventuellement en parametre le fichier source (sinon c’est l’entree standard qui sera utilisee):
tr "àçéèêëîïôöùüÂÇÉÈÊËÎÏÔÖÙÜ" "aceeeeiioouuACEEEEIIOOUU"

foo2
| uniq myFile.txt |
