Gnasher alleviates developers from having to execute maven builds with the "-o" option (offline) to avoid accessing external repositories' metadata files. The SHA1 hash files and the missing pom metadata files for dependencies are created if they are missing. The next time the build is run, external repositories are not accessed and the build runs faster.
iLAP (Laboratory data management, Analysis, and Protocol development) is a workflow-driven information management system specifically designed to create and manage experimental protocols and to analyze and share laboratory data. The system combines experimental protocol development, wizard-based data acquisition, and high-throughput data analysis into a single, integrated system.
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).
XWelltris is a 2.5D Tetris-like game. Imagine that you are looking into a glass from the top. You see four walls and the bottom. Flat 2D figures fall down from the walls one by one. You can move these figures from one wall to another or rotate them. If the figure leaves the wall, then it moves to the bottom while another figure is pushed. You need to form full rows or columns on the bottom. When you form such row it disappears and you receive additional empty space on the bottom and your score increases. Extra points are earned by making more rows disappear at the same time. If you can't place a whole figure on the bottom, then it stays on the wall and you can't place figures on that wall for a while.
