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).
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.

Adianti Studio is a multi-platform environment for PHP development which includes a great range of resources a developer needs to be productive. It uses a tabbed interface which brings basic resources like syntax highlighting, auto-complete, an outline tree, bookmarks, code insight, change tracking, method traceability, workspace saving, brace matching, source code navigation, database navigation, a plugins gallery (managed by the user), a PDF document generator, a calendar, and more. In the professional version, it adds a form design tool called Adianti Designer which allows the user to draw its forms with a graphical interface using Adianti Framework components and containers like inputs, combos, radios, check buttons, imagens, frames, notebooks, datagrids, and more. The professional version also offers a source code generator which allows the user to generate form classes and datagrid classes from database structures using the Adianti Framework pattern of source code.
Adianti Framework provides an architecture for developing PHP applications, reducing development costs, and helping developers write less code. It is a component-based and event-driven framework which uses commonly-known enterprise design patterns like MVC (Model View Controller), Front Controller, and ORM (Object-Relational Mapping) design patterns like Active Record and Repository. It provides two different widget toolkits, one for Web applications (HTML/CSS) and another for graphical applications (with a Graphical User Interface) which uses Gtk internally. The developer can write one set of code, and it can run in a Web environment and also as a graphical application.
Bookling is a simple eBook manager designed to make reading fun. It allows you to store, manage, and read your eBook collection on a desktop computer. It features multiple views for your library, multiple bookmarks, customisable fonts and colors for your book's text, and the ability to store your book collection in your choice of directory. Its back end is cleanly separated from the front end, allowing developers to easily port it to other platforms with a native GTK+ or WPF interface.
