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.
Processdsn consumes RFC 3464 delivery status notification email messages, writing a summary of the notification to a SQL database. Notifications may indicate successful delivery, a delay in delivery, or delivery failure. The database is designed to be exposed restfully by the mod_processdsn module for Apache httpd, but can queried directly if necessary.
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).
bgpfeeder is a program to feed a BGPv4 speaker with an infrequently changing list of static internal routes. It is used at Bytemark to rearrange routing information from the "network organizer" database, to avoid staff having to log in to core routers to effect common routing changes. It is also used to communicate with transit providers to communicate "black hole" information about traffic that should not be passed on to the routers.
