Udis86/64 is (as of now) a binary file disassembler for the x86 and x86-64 (AMD64) architectures, capable of disassembling 16/32/64 bit binary files to AT&T or INTEL assembly language syntax.
[COPYRIGHt=1] Udis86 focuses on providing the basic disassembler functionality in executable format as well as a static library libudis86.a for use as the core of object/executable file diassembler programs.
Enhancements:
- Decode fixes.
- Fixed buffer overrun vulnerabilities. Input streaming is more robust now.

log4javascript provides JavaScript developers with a familiar, robust, and flexible logging framework with which to debug JavaScript applications. This is becoming increasingly important as Web interfaces become richer.
log4javascript is based on Javas log4j and is tested and works across all recent major browsers, including IE5+ (for Windows), Firefox, Mozilla, Netscape 7+, Safari 1.3+, and Opera 7.5+.
Enhancements:
- Fix to interaction of search and severity filters in console window used by PopUpAppender and InPageAppender

Wykobi project is an efficient, robust, and simple to use multi-platform 2D/3D computational geometry library.
Wykobi provides a concise, predictable, and deterministic interface for geometric primitives and complex geometric routines using and conforming to the ISO/IEC 14882:2003 C++ language specification.
The design and structure of Wykobi lends itself to easy and seamless integration into projects of any scale that require a robust yet efficient 2D/3D computational geometry back-end.
Enhancements:
- Various algorithms were added, including 2D only Convex Hull algorithms (Graham scan, Jarvis march, and Melkman), Minimum Bounding Ball algorithms (Naive method (2D), Randomized (2D), and Ritter (2D and 3D)), Sutherland Hodgman polygon clipper, isotropic point normalizations (2D and 3D), covariance matrix calculation for point clouds (2D and 3D), ordered polygon from complex self-intersecting polygons (2D). naive group based pairwise intersections, axis projection polygon descriptor, a duplicate removal algorithm, and matrix calculations (2x2, 3x3, and 4x4).

omniORBpy is a high-performance CORBA 2.6 ORB for Python. omniORB is largely CORBA 2.6 compliant.

omniORB is one of only three ORBs to have been awarded the Open Groups Open Brand for CORBA. This means that omniORB has been tested and certified CORBA compliant, to version 2.1 of the CORBA specification. You can find out more about the branding program at the Open Group.

OpenSER is a collaborative project of its users, to develop a scalable and robust SIP server.
Anyone can contribute to one of next items:
- code development - OpenSER core, modules and adjacent applications
- documentation- writing or enriching documentation
- miscellaneous - different management tasks (e.g., web site maintenance)
- ideas - new ideas bring brilliant solutions
Main features:
- robust and performant SIP (RFC3261) Registrar server, Location server, Proxy server and Redirect server
- stateless and transactional statefull SIP Proxy processing
- support for UDP/TCP/TLS transport layers
- scripting language for configurations file. With a syntax similar to sripting languages, the configuration offers a powerful and flexible way to deploy custom SIP services.
- management interface via FIFO file and unix sockets
- pseudo-variables to access and manage parts of the SIP messages and attributes specific to users and server
- authentication, authorization and accounting (AAA) via database (MySQL, Postgress, text files), RADIUS and DIAMETER
- CPL - Call Processing Language (RFC3880)
- NAT traversal support for SIP and RTP traffic
- ENUM support
- load balancing and least cost routing extensions
- support for replication - REGISTER offer new functions for replicating client information (real source and received socket).
- logging capabilities - can log custom messages including any header or pseudo-variable and parts of SIP message structure.
- modular architecture - plug-and-play module interface to extend the servers functionality
Enhancements:
- This is the second patch release in 1.2.x series, including minor enhancements and bugfixes done since 1.2.1 was released.

Poseidon provides yet another PHP weblog, but with a robust plugin API.

Poseidon is yet another PHP weblog, although its goals are a little different from most.

Poseidon is intended to be as small, simple, and cleanly organized as possible. It does its job, which is to manage content and allow user feedback via comments, and thats it.

Its features can be enhanced and extended via a robust event-driven plugin API, so you never have to install features you wont use.

Great care has been taken to exercise the best possible coding practices. Simplicity is always favored over cleverness. Poseidon speaks to MySQL on the back end and spits out 100% valid XHTML on the front end, using CSS to handle design and layout.

Thus, by spending some time tweaking CSS files, you could easily give your entire Poseidon-based website a radically different design, even going so far as to move individual elements around or eliminate them completely.

The goal of all of this is to give you the simplest possible method for customizing and running a weblog without having to do a lot of work.
