Git is a distributed version control system, originally designed for Linux kernel development and large projects with non-linear workflows. It's comprised of individual tools, reuses ssh and rsync protocols, emphasises speed and data integrity, and keeps every checkout as full-fledged repository, and cryptographically authenticates source history. Various graphical frontends, IDE integrations and web services (GitHub) exist; with its git-fast-export format meanwhile serves interoperability with
The GIFLIB project maintains the giflib service library, which has been pulling images out of GIFs since 1989. It is deployed everywhere you can think of and some places you probably can't - graphics applications and web browsers on multiple operating systems, game consoles, smartphones, and likely your ATM too. Yes, this code is he reason GIFs were in Mosaic, the first web browser that could do inline graphics; it is the implementation Andreesen and Bina used. This is very mature, stable, sma
libunwind is a portable and efficient C API for determining the current call chain of ELF program threads of execution and for resuming execution at any point in that call chain. The API supports both local (same process) and remote (other process) operation. The API ise useful in a number of applications, including but not limited to the following. Program introspection: Either for error messages showing a back trace of the call chain leading to a problem or for performance monitoring and ana
If you are not familiar with Open Inventor, it is a scene graph based, retained mode, rendering and model manipulation, C++ class library, originally designed by SGI. It quickly became the de facto standard graphics library for 3D visualization and visual simulation software in the scientific and engineering community after its release. It also became the basis for the VRML1 file format standard. Several books exists on the subject of Open Inventor, most notably The Inventor Mentor, and The Inve
