Portfolyo project is a Web-based personal project and skill tracker.
Portfolyo is a Web-based tool for professionals to manage their portfolios and, in a broader sense, all information that constitutes them as professionals.
It aids you in keeping track of your projects and skills, and it presents the captured data on your Web site to show off to potential clients, employers, or your peers.
Its a CGI application written in Python.
Main features:
- Manage and track your projects and skills in a web-based administration interface
- Present a list of your projects and detailed views of them on your website
- Present a "skills matrix" on your website, which transparently associates skills with your level of experience and related projects
- Customize look and functionality of your portfolio by editing HTML templates
- Import/export all data to/from a flat file

GStreamer is a library that allows the construction of graphs of media-handling components, ranging from simple Vorbis and Ogg playback to complex audio (mixing) and video (non-linear editing) processing.
Applications can take advantage of advances in codec and filter technology transparently. Developers can add new codecs and filters by writing a simple plugin with a clean, generic interface.
Main features:
- Parallel installability with 0.8.x series
- Threadsafe design and API
- new id3 demuxer (replaces the mad one in gst-plugins-ugly)
- memleak fixes in avidemux, wavparse, level, smoke
- ports of multipart,
- fixes in flacdec, flxdec, rtp
- documentation updates on videomixer
- added new sunaudiosink, gconfaudiosrc and gconfvideosrc elements

Bitgate Server Software Environment aims to build a multi-protocol environment in which server protocol handlers can be eventually loaded and unloaded on the fly using a center console or controller Web page.
Bitgate Server Software Environment aims to have 99.9% uptime, and have high-availability (Java 6) compliance. It is written in Java 5, and relies completely on Javas I/O functionality to provide non-blocking support for both SSL and non-SSL sockets (transparently).
All configuration is done via XML files, as this is easier to maintain. It includes a minimal demonstration HTTP server.
Enhancements:
- Modified HTTP directory listing to be a little more clean on the output of filenames; shows more information about each file in question as well.
- Added "reset" methods to the ClientContext objects so that Keep-Alive requests are now handled properly.
- Implemented 302 redirects and space encodings on filenames.
