epers stands for "Erlang persistence". As the name suggests, it tries to make it easy to use databases in Erlang programs, to make the language a little more agile, and (humbly) offer a nice adapter for several databases, hiding their implementation details (and the API of the library/framework/driver used to communicate with them). To achieve this, it aims to offer a somewhat consistent API to define and work with your model, while at the same not coupling your code too tightly to it.
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).
TeXstudio is a fully featured LaTeX editor. It is designed to make writing LaTeX documents as easy and comfortable as possible. It features an integrated PDF viewer with (almost) word-level synchronization, live inline preview, advanced syntax highlighting, and live checking of references, citations, LaTeX commands, spelling, and grammar.
Higgs.IO is a high performance, message oriented network library built for realtime systems. It provides a core extensible framework and libraries built on top of the core. Libraries include a WebSocket server, an HTTP server and client, and Boson, a custom serialization and RMI library.
Nibble Forms 2 is a PHP form class which allows developers to quickly create HTML5 forms and validate submitted results. An evolution of the original Nibble Forms class, it follows some of the key principles of Nibble Forms: It's simple to instantiate, it uses simple form field calls, it's flexible, and it provides validation out of the box.
Slim HTML5 Audio jQuery Plugin is a very simple jQuery plugin to embed an audio player. It can insert HTML to play a given audio file using the HTML5 audio tag. It also inserts the embed container tab as fallback when the audio tag is not supported by the Web browser (e.g., IE7 and 8).
