Eero is a binary-compatible variant of Objective-C 2.0, implemented with a patched version of the Clang/LLVM compiler. It features a streamlined syntax with improved readability and reduced code clutter, as well as new features such as Python-like indentation and a limited form of operator overloading. It is inspired by languages such as Smalltalk and Ruby.
FEHASHMAC is a collection of publicly known hash algorithms integrated into a command-line utility. Currently 42 hash algorithms belonging to 12 algorithm families are supported, including the five SHA-3 finalist contributions, plus HMAC for each algorithm. FEHASHMAC contains a set of over 540 known test vectors and results for each algorithm such that the correct implementation for each hardware platform and compiler version can be directly verified. FEHASHMAC supports bitwise hash calculation for algorithms with available bitwise test vectors. Currently this applies to the SHA algorithms: sha1, sha224, sha256, sha384, sha512, and to the five SHA-3 finalists. The so-called Gillogly bitwise input has only been tested for sha1, but is also implemented in the SHA-2 hashes. Bitwise hash calculation is also supported in sha512-224, sha512-256, and whirl, but there are no bitwise test vectors available. FEHASHMAC can also calculate hashed message authentication codes (HMAC).
Kittens is an application container that can embed X applications and steal them from your window manager in order to provide advanced window management options to any window manager. It can tab windows together, split to show them vertically side by side, and allow applications and splits to be resized with the mouse or keyboard. It works in environments such as GNOME, KDE, and XFCE. Kittens is also ideal for managing applications without having to use a mouse.
