Se la jouer avec la VM linux
Source: http://blog.nasa.fr/wp/linux/2011-02-18/se-la-jouer-avec-la-vm-linux/Vous voulez jouer au malin avec la gestion Virtual Memory de linux… Ce tips est pour vous. Il permet de vider la mémoire cache et avoir de la mémoire libre.
Mais j’entends au fond de la salle : qu’est-ce qui est dans le cache ?
Et bien facile, mon ptit gars… il va contenir les fichiers qui sont extraits du disque avant d’être utilisés. Le but est d’accélérer l’accès lors d’une lecture suivante.

A ben voilà une nouvelle pour Geeker un peu avant de reprendre le travail Lundi matin. Deiban 6.0 vient de sortir, “Squeeze” avec quelques petits concepts innovants. -
Port Serie Saison I
Et ben, voila j’ai perdu un écran sur la machine qui me sert de routeur. Sans clavier ni écran le diagnostique n’est pas facile en cas d’erreur. Mais heureusement le mode console est là. Je ne sais pas depuis combien de temps cela existe dans le kernel, mais je pense que cela ne doit pas être loin des origines. -
Linux Mint 7 Gloria
I have been using Linux for ten years now and like most of you I like to try different distributions. A few months ago I discovered Linux Mint while browsing on DistroWatch. I was surprised to see that Linux Mint was really popular (I think it was 4th at that time) and just now it’s the 3rd most popular Linux distribution…
Linux Mint, which is at version 7 now, is based on Ubuntu which itself is built on Debian. So we’re in excellent company here.
These are the things in Linux Mint that I really like:
- Linux Mint contain codecs for most of the media files (audio / video) found on the Internet out of the box.
- The user interface is gorgeous and really feels like something that has been designed by someone who really knows about user interaction. For example, Mint has a menu (pictured above) which contains selected applications (favourites) and which is 100% customisable. It’s much better (IMHO) than the default Gnome menu.
- There is an application which shows all software available in Linux Mint with screenshots. What is great is that this list can be sorted by popularity. It’s a great way to discover open source applications which are used by a lot of people and which you don’t personally know about.
- Compiz (as well as the proprietary Nvidia driver in my case) is preinstalled and is sensibly configured: not a lot of eye candy but, instead, a pragmatic choice of settings to make Gnome more usable.
- aptitude! I love anything .deb-based.
I’m really impressed by Linux Mint. This is the only distribution I use at home. At work I use CentOS Linux because, well, it is great for a business environment. But I might replace CentOS on my own computer there with Linux Mint. Just don’t tell anyone.

What do you think of Google Chrome OS?
Two days ago, Google announced the Google Chrome OS (Operating System) project.
Google Chrome OS can be seen as Linux with a special window manager to only allow one application: the Google Chrome web browser. In essence, a computer running Google Chrome OS will only have one application, a web browser. This means that the user will only use web-based applications presumably (but not forcibly) from Google (e.g. Gmail, Google Docs, etc.)
Google will initially launch this OS on netbooks (those ultra small laptops with small screens.) Netbooks account for only a few % of the market and most people use them for browsing only so this seems a sensible strategy (it would have been stupid to launch the OS on full-fledged PCs as people would have immediately requested for “Photoshop on the web”.)
Our friend, Fake Steve, is adamant that building Google Chrome OS is not a good stategy for Google. In my opinion, he is correct when he questions the business logic of Google. You see, Chrome OS is going to be free (like most Linux distributions), has one good browser (like most Linux distributions), with good support for Google apps (like most Linux distribuions) but is going to be costly to build for Google (unlike most Linux distributions which exist already.) So why build yet another Linux distribution (which is what Google Chrome OS is in essence…) Why don’t Google use something which exists already?
What do you think?

/proc le coffre aux trésors
Autour du kernel, nous utilisons tous une foule de programmes pour récupérer les informations et utiliser notre système du mieux possible. Sous linux, toutes ces informations sont accessibles via /proc. Un peu de curiosité vous montrera les bijoux techniques qu’il est possible de récupérer.

The Sony Bravia LCD TVs run Linux
How many of you would like to get an LCD TV for Christmas? A lot, I bet. How many of you know that the Sony Bravia LCD TVs are powered by Linux? A lot fewer, I guess.
LCD TVs have a lot of pixels. When displaying a normal-resolution programme (say from the MBC), the TV must use extremely complex image processing algorithms to generate the missing pixels. For example:
- SECAM @ 720 x 576 = 414,720 pixels every 1/25 of a second (I’m simplifying…)
- HDTV @ 1920 x 1080 = 2,073,600 pixels every 1/25 of a second
So the TV must digitally create 5 times as many pixels as in the original frame 25 times per second. As you can easily guess, this requires a lot of horsepower hence the use of a powerful computer inside the TV. Sony has chosen Linux to power that computer (specifically Linux kernel 2.6.11)
For the more curious, have a look at http://products.sel.sony.com/opensource/source_tv.shtml

Our July meeting
The next LUGM meeting will take place at the usual venue on 4 July 2009 at 10:00. A tentative agenda is:
- Status of registration of the association
- Status of the development and deployment of the new website
- Involvement in the Fedora Electronic Lab distribution (made by a Mauritian, Chitlesh Goorah!)
- AOB
The meeting will be followed by a technical presentation (the exact topic will be confirmed in a few days) and we’ll have lunch together afterwards.
Everyone is invited!
