As a software/game developer you, usually, want more and more... of everything actually! More pixels, more triangles, more FPS, more objects on the screen, bots, monsters. Unfortunately you don't have endless resources and you end up with some compromises. The optimization process can help in reduction of performance bottlenecks and it may free some available powers hidden in the code.

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.

Is it possible to imagine a future where “concert programmers” are as common a fixture in the worlds auditoriums as concert pianists? In this presentation Andrew will be live-coding the generative algorithms that will be producing the music that the audience will be listening too.

Lorsque l'on dispose de plusieurs versions installables dans les dépôts renseignés dans les fichiers sources.list, il faut définir des priorités pour que APT sache quelle version installer.

Par exemple, si l'on a les dépôts Debian de testing et unstable et que l'on veut rester autant que possible en testing, il faut indiquer à APT que testing a une priorité supérieure à sid. Inversement, si pour un paquet donné on veut utiliser sa version présente dans sid, il faut le spécifier également. La définition de ces priorités s'appelle le pinning.

CMake actually defines several variables to identify the platform information. These variables will be assigned with the values based on the platform, operating system etc.

For example, In CMake version 2.6 following Variables are present to identify the Operating System Type.

UNIX is TRUE on all UNIX-like OS's, including Apple OS X and Cygwin.
WIN32 is TRUE on Windows, including Cygwin.
APPLE is TRUE on Apple systems.

If you've never had problems keeping your clock synced, you just haven't run enough machines yet. Once you start scaling beyond a certain point, it will become obvious that even elementary timekeeping is no small feat, even with help from tools like ntpd.

Hardware performance monitoring counters have recently received a lot of attention. They have been used by diverse communities to understand and improve the quality of computing systems: for example, architects use them to extract application characteristics and propose new hardware mechanisms; compiler writers study how generated code behaves on particular hardware; software developers identify critical regions of their applications and evaluate design choices to select the best performing implementation. We propose that counters be used by all categories of users, in particular non-experts, and we advocate that a few simple metrics derived from these counters are relevant and useful. For example, a low IPC (number of executed instructions per cycle) indicates that the hardware is not performing at its best; a high cache miss ratio can suggest several causes, such as conflicts between processes in a multicore environment.
