SIMtrace sniffs communication between a mobile phone and a SIM/USIM card. This can be useful for research and analysis, and for developing mobile phone and SIM toolkit (STK) software. The SIMtrace hardware is also capable of MITM (man in the middle) attacks on the SIM-MS communication.
Five Hundred is a card game for four players similar to Euchre or Bridge, especially popular in Australia and New Zealand. The wikipedia page has a comprehensive description of gameplay. This version is implemented in C++/Qt. It incorporates graphics from the svg-cards project. Computer players are scriptable in Lua.
Anywhere Board Games (ABG) allows users to play board and card games on the Web in real time on multiple machines (PC, Linux, iPhone, iPad, and Android). ABG runs as a Google+ Hangout App or as a standalone PHP app. Unlike other gaming environments, this one has a peculiar vision: projecting the main board on our table and using laptops or tablets to control players' hands (with other friends joining in remotely). It supports flipping, stacking, rotating, rolling, and shuffling of pieces, so most board and card games are playable.
D:GameVFS is a minimalist virtual filesystem library for the D programming language oriented at game developers. It provides an easy-to-use API for filesystem-independent file/directory manipulation. It supports basic VFS functionality. Files and directories can be created, read, and written, but not deleted. There are no security features (e.g., D:GameVFS can't handle a situation in which a file it's working with is deleted outside the program).
POSIXplorer will help you find, navigate, and open files on Linux, Mac OS, or most POSIX systems. You just type the command and then a regex for which you'd like to search. By default, it searches filenames and excludes class and other data files. It looks recursively down from your current directory. If you'd like to search through file contents, use the '-c' flag. When using -c, after the regex, you can list a file pattern, such as * (the default) to match any file or *.java to match Java files. After searching on your query, it presents a list of results and lets you type a number to select one for opening in the editor you have defined in the EDITOR environment variable, or by default Vim. After quitting the editor, you come back to your results and can continue opening files or execute a new search. To run a new search, just type the query and the script will detect that you did not intend to enter a file number. Note that in content searches with -c, only a new content query can be entered, not a new file filter.
APF is a code generator that codes your software as you drag and drop code-abstracts on a canvas. It can be trained by the community to code almost anything. With automatic programming, it will sometimes code 50% to 100% of small or large software projects. APF has successfully shipped some real life software. But APF must produce more diverse software projects. You can help APF grow by picking re-usable code from any existing open source. 'Metacode' that code and submit it to the APF marketplace. APF feeds on re-useable code submitted by the community. This way, APF gets trained to auto code more and more. You can also improve the way APF assembles code, or the way its Canvas lets the user drag and drop code abstracts.
MrsWatson is a commandline audio plugin host. It takes one or more plugins, sends an audio signal to them for processing, and saves the resulting output. Although the plugins think they are running in realtime, processing is actually done offline (this is not the same as the "offline" processing in VST terminology). This makes MrsWatson ideal for developing or debugging plugins, or processing audio on a server.
