MultiSystem est un logiciel qui, contrairement aux outils traditionnels comme LinuxLive USB Creator, Usb-creator, ou encore Unetbootin, permet de créer entre autres des clés dites Live-USB mais multiboot. C'est-à-dire que vous pourrez installer autant de Live-CD que l'espace disponible de votre clé USB le permet et choisir au démarrage de votre PC, via un menu graphique, la distribution ou le Système d'exploitation à démarrer.

Linus Torvalds transformed technology twice -- first with the Linux kernel, which helps power the Internet, and again with Git, the source code management system used by developers worldwide. In a rare interview with TED Curator Chris Anderson, Torvalds discusses with remarkable openness the personality traits that prompted his unique philosophy of work, engineering and life. "I am not a visionary, I'm an engineer," Torvalds says. "I'm perfectly happy with all the people who are walking around and just staring at the clouds ... but I'm looking at the ground, and I want to fix the pothole that's right in front of me before I fall in."
Context switch overhead is discussed and thread states are introduced.
This blog post explains how Linux programs call functions in the Linux kernel.
It will outline several different methods of making systems calls, how to handcraft your own assembly to make system calls (examples included), kernel entry points into system calls, kernel exit points from system calls, glibc wrappers, bugs, and much, much more.
Des retours sur ces portables?

Ils se touchent un peu avec leurs prix à la apple.
http://www.dell.com/fr/p/xps-13-9350-laptop-ubuntu/pd?ref=PD_OC
1229€ pour le premier prix. écran mat non-tactile, core i5, 8GB, 256GB SSD. A 900€ je dis pas, mais là c'est abusé.
Les autres ont un écran tactile, donc brillant (et donc ne m'intéressent pas).
Dell's Project Sputnik fills a vacuum because it is the only major PC maker with such a Linux effort under way. Some other PC makers like System76 also offer Linux laptops, but Dell's laptops have a wider reach.
Dell's wider focus will remain on Windows for its PCs, and Project Sputnik is still seen as a "skunkworks" project directed at Linux enthusiasts. There were some doubts within Dell initially over the project's purpose, but acceptance has grown over the years, as Linux serves a niche, but important, market, George said.
Bien.
En gros si je résume l'article, il y aura plus de portables sous linux, à travers le projet 'sputnik'. A voir.
Une doc assez complète sur systemd, puisque c'est l'avenir.

The TTY subsystem is central to the design of Linux, and UNIX in general. Unfortunately, its importance is often overlooked, and it is difficult to find good introductory articles about it. I believe that a basic understanding of TTYs in Linux is essential for the developer and the advanced user.

Excellent cet article.
J'ai découvert pidstat (provient du paquet sysstat), mpstat, et je ne savais pas que sar permettait d'analyser la bande passante par interface réseau.
Un article sur IPVS qui existe depuis 15ans dans le kernel linux, et qui reste une petite perle. Je rappele que c'est basé sur netfilter.
Bonnes perfs:
"""
In testing, IPVS’ performance was nearly the same TPS as a normal connection. HAProxy and MySQL proxy were around 60 percent of its speed.
"""
Quelques bénéfices qui peuvent pousser son adoption:
"""
UDP support
Dynamically configurable
More than eight balancing methods
Health checking
"""
Conclusion:
"""
To conclude his talk, Sibiryov briefly compared IPVS to a $25,000 enterprise hardware load balancer. While GORB is still relatively new (he cautioned to watch out for bugs), IPVS is open-source, configurable, and like GORB, it’s also free. It requires no special software or tools, and can leverage a 1 GBPS line with only 1 percent CPU usage in DR mode (MAC L2).
Plus, IPVS has a 1,000-word man page instead of a vendor manual, and let’s not forget that it’s 15 years old. Simplicity and stability, Sibiryov stressed, make IPVS a serious alternative to enterprise load-balancing hardware.

Je mets de coté ce thread qui liste les releases de l'éditeur Unity3D sur Linux.
Les coulisses: http://natoshabard.com/post/122670082502/porting-the-unity-editor-to-linux-stuff-i-wish
Moi ça m'intéresse juste pour pouvoir lancer les jeux mobiles qu'on fait avec ce framework dans ma boite, sur mon poste - pour tester.
EDIT0: there is a docker for that https://github.com/tommyoshaw/unity3d
EDIT1: L'éditeur/player c'est pour du Unity 5. Donc au pire, wine pour du Unity 4 => https://github.com/Unity3D-Wine-Support/Unity3D-on-Wine
