Weed-FS is a simple and highly scalable distributed file system. There are two objectives: to store billions of files, and to serve the files fast! Instead of supporting full POSIX file system semantics, it implements only a key-file mapping. Instead of managing all file metadata in a central master, it manages file volumes in the central master and lets volume servers manage files and the metadata. This relieves concurrency pressure from the central master and spreads file metadata into volume servers' memories, allowing faster file access with just one disk read operation. It is modelled on Facebook's Haystack design paper. Only 40 bytes of disk storage are required for each file's metadata, and disk reads are O(1).
SharpTAL compiles XML-based templates to .NET assemblies. It contains a complete implementation of the Zope Page Templates (ZPT) language, a system which can generate HTML, XML, or plain text output. ZPT is formed by the Template Attribute Language (TAL), the Expression Syntax (TALES), and the Macro Expansion Template Attribute Language (METAL).
GriF is a collaborative grid framework to support computational chemistry applications. It is meant to be used as a tool to facilitate massive grid calculations and also to improve scientific collaboration. Accordingly, GriF facilitates profiling the users of grid communities in order to systematically evaluate the work carried out in a grid and to foster its sustainability.
Scriptella is an Extract-Transform-Load (ETL) and script execution tool. Its primary focus is simplicity. It doesn't require the user to learn another complex XML-based language to use it, but allows the use of SQL or another scripting language suitable for the data source to perform required transformations.
OrientDB is a NoSQL DBMS which can store 150,000 documents per second on common hardware. Even with a document-based database, the relationships are managed as in graph databases, with direct connections among records. You can traverse entire or parts of trees and graphs of records in a few milliseconds. It supports schema-less, schema-full, and schema-mixed modes, has a strong security profiling system based on users and roles, and supports SQL between the query languages. Thanks to the SQL layer, it's straightforward to use for people skilled in the relational world.
Pocket Bandit is a slot machine game for Android. It features a retro style with three reels and ten stops, and is modelled after the classic, mechanical fruit machines of the early 20th century and emulates devices such as the Mills Novelty QT Chevron, Mills Novelty Vestpocket, Groetchen IMP trade simulator, Pace Comet, and Liberty Bell. Unlike the original machines, it also includes elements of skilled and strategic play. You can spin the reels at different speeds by pulling the knob at different speeds, stop a reel at will by yanking the knob up, wager zero to three coins per round, and use no-wager rounds to skip over bad luck streaks.
