PhotoCatalog can import GPS data from various formats such as CSV, GPX, and InstaMapper (in the case of InstaMapper, it is a live stream) and create a Map that is updated live during your travels. It can also import data from Twitter or FourSquare, RSS extract any GPS data they have or supplement them with existing GPS data, and place them on a map as well as keeping a personal archive. It can then import photos via file upload, email, or scanning an existing folder, geotag photos lacking GPS data, sort, rotate, scale, and [losslessly] compress them as necessary and place them on a map. It can also push them to Facebook automatically and fill in a caption and/or comment with them.
SafePatch lets you edit program files and track those changes creating "patches" which can later be reverted or reused in a different setup. It's written in PHP, but can patch non-PHP applications because no integration into their source code is required. A bundled Control Panel allows easy tracking, installing, reverting, and diffing of available patches. SafePatch has an intuitive text patch file syntax which is uniform for text and binary files and independent of the engine being patched, has default support for VQMod .xml patches and FluxBB README mods, is written in OOP and uses events (and thus is easily extensible), and doesn't need a database.
SearchBin is a fast commandline program for searching within binary files. It's a bit like grep for binaries. It offers wildcard matching and has three capabilities for searching: for bytes using hexidecimal, for a plain text string, and for a smaller binary file. Any discovered matches will print the found offsets (0-based).
HGL is a compiler/interpreter suite for developing images. It features its own simple but powerful language, Lua integration, output in various formats as well as runtime input handled by plugins, and easy integration into various environments like Web servers or graphical applications. The input is taken from a source file, which has to be compiled for quick and frequent access by the interpreter. An interpreter then runs the compiled files, takes input from custom plugins (if neccessary), and outputs its result via custom plugins.
