Dr Jekyll & Mr Hyde

Comme je l’avais expliqué dans Asterisk - build your own PBX, la prise téléphonique de ma Freebox était connectée à mon PC par une interface analogique de type FXO. Sur le PC, qui tourne sous GNU/Linux, l’autocommutateur libre Asterisk gère mes communications et mes services. Tout fonctionnait correctement, même si la reconnaissance du raccroché du […]

Existing distributed rendering systems such as DrQueue were fine but require that some software other than Blender or basic interpreters (such as Python or Perl) is installed on the contributing machines.
So I […]

I always tell my compilation class students that there are two steps to follow when developping a new program:

the program must accept any valid input and produce accurate results; the result of feeding the program with invalid input is undefined, it can either crash or silently produce wrong results;
the program must reject any invalid input.

I have just released the new version of recoverjpeg (1.1), a software allowing you to retrieve pictures from corrupted digital media. This version adds two output file name formatting options, thanks to Pierre Beyssac for his contribution.
