basE91 is an advanced method for encoding binary data as ASCII characters. It is similar to UUencode or base64, but is more efficient. The overhead produced by basE91 depends on the input data. It amounts at most to 23% and can range down to 14%.

CADI is an implementation of the JPIP standard (JPEG2000 Interactive Protocol - Part 9). CADI includes a JPIP server, a JPIP proxy, and a JPIP Client. CADI is designed and programmed with the aim to provide a flexible framework to test and develop ne

Open Source IM and voice client using Jabber and SIP protocols, with great audio quality thanks to speex and a nice and clean interface. Programmed in Java and C++. It supports chat, voice and file transfers.

OptorSim is a Grid simulator designed to test dynamic replication strategies used in optimising data location within a Grid. Each simulated site contains several storage or computing elements. Simulated jobs run and file accesses may trigger replication.

This application talks to a GPS device over the NMEA protocol via the WIGSGPSComm API. The first version of the WIGS application will present the GPS data in an intuitive fashion, and later releases will be further enhanced with special map support.

The Asterisk Config PHP-Parser claims to be a simple but effective function writen in PHP non-OOP that is capable to parse any standard .conf Asterisk configuration file an drop the data into a multi-dimensional array.

Provide geneology information, contact information, personal descriptions and webpages, calendars, etc in a web interface. This system will use php and any database system and will provide various level of public and private access.

A p2p filesharing application, where every1 is forced to seed for a certain period and then every1 gets to download with a guaranteed number of seeders as well, for a certain perion of time.

Passwords generator for IAD devices, using 3 keys and a index. The result is a fixed lenght of alphabetic characters. The algorithm works with other 3 big fixed prime numbers. These 3 numbers define a family of passwords. Finally, it provides a guaranteed functional string to use in all variety of devices without rejects.

Der KND Decoder konvertiert die lästigen Zahlenwerte, in den Java Dateien vom Knuddels Applet, zu lesbaren Strings. Die neue dekodier Methode wurde auch beachtet, die den HuffmanString etc. konvertiert.

An attempt to design minimum cost broadband networks with the use of a modified version of the Particle Swarm Optimization method. A GIS subsystem is used for the visualization of data and results.

Secure P2P Instant Messenger running on .NET Framework 2.0. Uses server to store user information (user name, password, email address, friends list, log in state, IP address) in encrypted form. Uses custom designed symmetric encryption algorithm.

Centre is a synthetic trajectory generator environment that aim to generate semantic-based trajectory datasets usable for spatio-temporal data-mining algorithms in testing and validation process.

Teeser is a java-based integration framework for engineering emergent self-organizing behavior in distributed systems. It contains tools for analysis, tuning, macroscopic probing and simulations of distributed systems. Library of tools can be extended and everybody is encouraged to provide and share its tools with the community. The main idea is to provide application designers ability to seamlessly use tools which are helpful to design self-organizing behavior. Designers can continue to use their domain tools such as favorable simulator and by pluging it into the framework can take advantage of distributed simulations in the grid, various analyzers, optimizers (particle swarm optimization, genetic algorithms, ...). See Wiki pages for more information.

HOOPLE is a portable collection of C++ source code, featuring thread-safe objects for collections and event processing, RPC-style plugin-based encrypted networking (CROMP / octopus), bookmark collection management utilities, and a lot of other cool stuff. This is the project page for HOOPLE version 1, which was retired on September 25 2010. The code supposedly still builds on both Linux (with gnu gcc) and on Windows (with ms visual studio). Most of the code from hoople1 has moved into the Feisty Meow® Concerns Ltd codebase, available at http://feistymeow.org for your enjoyment.

The FCC publishes pools of questions for each of the three Amateur Service (Ham Radio) license exams. Two of my programs clean and parse the files and put the questions and answers into a small lightweight database (SQLite) file. The third program generates practice tests which you can focus on particular areas of the exam or randomly select across the pool. The db file in the project is up to date as of February 3rd, 2020. When the FCC issues new/updated exam pools you can use the cleaning and parsing programs to update the database information. The project includes source code files. You may use them in your projects but you must give me attribution according to the GNU License Version 3.

pycrc is an easy to use CRC (cyclic redundancy check) calculator and C source code generator. The generated source code can be optimized for simplicity, speed or space. pycrc contains a long parameter list of common CRC models. The program is self contained and does not require installation. Apart from a python installation, it does not require other libraries to be installed.

A collaboration platform that enables non-locking, synchronous, real-time collaborative (NOT text only) editing with editor independence. It also provides edit by edit session playback. To collaborate just enter a name, group and password.
