Un git merge ne devrait être utilisé que pour la récupération fonctionnelle, intégrale et finale d’une branche dans une autre, afin de préserver un graphe d’historique sémantiquement cohérent et utile, lequel représente une véritable valeur ajoutée.

Tous les autres cas de figure relèvent du rebase sous toutes ses formes : classique, tri-partite, interactif ou cherry picking.

It doesn't make any sense to talk about lock free data structures without covering such topics as atomic operations, memory model in programming languages, safe memory reclamation, compiler and optimizations used by them, modern CPU designs, — all of these topics will be covered more or less in this series.

This is the web site for the Third Edition of Linux Device Drivers, by Jonathan Corbet, Alessandro Rubini, and Greg Kroah-Hartman. For the moment, only the finished PDF files are available; we do intend to make an HTML version and the DocBook source available as well.

On i386, because of the dearth of general-purpose registers, the calling convention passes all arguments on the stack. This makes the vaarg implementation easy – A valistis simply a pointer into the stack, andvaargjust adds the size of the type to be retrieved to thevalist, and returns the old value. In fact, the i386 ABI reference simply specifiesva_arg in terms of a single line of code:

On amd64, the problem is much more complicated. To start, amd64 specifies that up to 6 integer arguments and up to 8 floating-point arguments are passed to functions in registers, to take advantage of amd64's larger number of registers. So, for a start, va_arg will have to deal with the fact that some arguments may have been passed in registers, and some on the stack.

How does a system call is handle in the linux kernel ?

How do we write a lot of data to disk really fast?

Facebook Notes allows users to include <img> tags. Whenever a <img> tag is used, Facebook crawls the image from the external server and caches it. Facebook will only cache the image once however using random get parameters the cache can be by-passed and the feature can be abused to cause a huge HTTP GET flood.

systemd0 is a replacement for the sysvinit daemon used in GNU/Linux and Unix systems, originally authored by Lennart Poettering of Red Hat. It represents a monumental increase in complexity, an abhorrent and violent slap in the face to the Unix philosophy, and its inherent domineering and viral nature turns it into something akin to a "second kernel" that is spreading all across the Linux ecosystem.

This site aims to serve as a rundown and a wake-up call to take a stand against the widespread proliferation of systemd, to detail why it is harmful, and to persuade users to reject its use.
