GGI stands for "General Graphics Interface", and it is a project that aims to develop a reliable, stable and fast graphics system that works everywhere. We want to allow any program using GGI to run on any platform requiring at most a recompile.

The Common Open Research Emulator (CORE) is a tool for emulating networks on one or more machines. You can connect these emulated networks to live networks. CORE consists of a GUI for drawing topologies of lightweight virtual machines, and Python modules for scripting network emulation.

Development of this project has been moved to https://github.com/jonelo/jacksum. This site has been left for historical purposes ONLY, you find older Jacksum versions here. Please visit the GitHub site for current development. Jacksum 1.7.0 is a platform independent checksum utility (written entirely in Java) for computing and verifying (integrity check) checksums, CRC and hashes (fingerprints). It supports 58 popular hash algorithms and a lot of unique features.

Prolog+CG is a Java implementation of Prolog with extensions implementing a subset of the Conceptual Graph (CG) theory of John Sowa. CGs are first-class datatypes on a par with terms. Object oriented extensions are also included.

YASP (Yet Another Simple Processor) is a 8-bit microprocessor with microcontroller capabilities (I/O ports, REQ, ACK) that can be used as a small computer for educational purposes. Its development environment includes simulators and assemblers.

Xena transforms files into open data formats for long-term digital preservation, encodes content in Base64 and wraps in XML metadata. Formats supported include MBOX, PST, MSG, DOC, XLS, PPT, RTF, PNG, XML, PDF, JPG, TIFF, PCX, WAV, MP3 and more. NO LONGER MAINTAINED, NO LONGER SUPPORTED

This is a simple application to bookmark/tag your folder/file. Filesystem will not be affected. You can add tag by directly right clicking the folder/file. For searching, approximate word matching is used. Files/folders will be sorted for required tags and the most matching will come on the top. For tagging websites, right now, you have to copy paste path. Plugin/extension for web-browsers need to be done.

This is a network simulator. This is meant to be user friendly as well as feature rich. This field lacks software with good user interface. Even the commercial softwares in this field is quite lame. This aimed to go along Multisim(R) and Blender(R) form
