Or patch it.

A flaw (said more critical than the Heartbleed attack) has been discovered in one of the oldest and most used program in UNIX machines : BASH.

Bash is the default system shell on most UNIX operating systems, including MacOSX and Ubuntu.

Basically the flaw could make a hacker able to access to private user information, and of course this could work remotely through networking (i.e via Internet too).

Facebook’s vision of C/C++ source preprocessing : Warp

Facebook_like_thumb

Warp is an open-source tool developed in D language to replace the original cpp (understand CPreProcessor, not C PlusPlus) when compiling C or C++ source code.

The main goal is productivity improvement, thanks to faster preprocessing. And for that, Warp relies on caching to achieve better preprocessing times.

Read this interview between Andrei Alexandrescu a Research Scientist at Facebook, and Walter Bright, the writer of Warp (these two guys are also the creators of the D language).
