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%.

the package chewingum contains two main programs: - base62 - chew They have been implemented in perl. Base62 has been coded in c++ too. chew has been written to shorten long decimal integer numbers into base62 strings. It's not a mere base conversion, because it doesn't use arithmetic inside its logic. In this way it can convert very long numbers into strings quickly, without overflows. For example if I want to share an id using an url, this will make the url shorter. the base62 program has been written to encode/decode files into this format. The syntax is similar to the popular base64 command line program. Inside the package there is a working c++ version of the base62 algorithm. the sources are inside the package. Note that from release 2.0.0 the algorithm is different from the one used before. If you have coded a file using base62 < 2.0.0 DO NOT USE base62 >= 2.0.0 to decode it. The 2.0.1 release has a new algorithm for chew, we have a compat flag

A threaded Web graph (Power law random graph) generator written in Python. It can generate a synthetic Web graph of about one million nodes in a few minutes on a desktop machine. It implements a threaded variant of the RMAT algorithm.

It moves by itself inside networks like virus infection & plagues, it is being written to solve computer virus problem drastically and responsibly. It is legal, free and open for public domain to improve W3 ICT Security.

C-squares is an easily implemented method for storage, querying and display of spatial data locations, based on a hierarchical, grid-based representation of the Earth' surface. Source code for encoding, decoding, mapping, etc. is provided via this site. Additional support is available by contacting the system developer, Tony.Rees@marinespecies.org; see also the c-squares home page at http://www.cmar.csiro.au/csquares/ .

A simple utility which creates a printable string of data usage. E.g. supply the value 1234567890 and DataUsagePrinter will return the string "1GB 153MB 384KB 722B". Available as binary and source downloads for Java and C#.

Gamoliyas is an open source John Conway's Game of Life game totally written in DHTML (JavaScript, CSS and HTML). Uses mouse and keyboard. Very configurable. This cross-platform and cross-browser game was tested under BeOS, Linux, *BSD, Windows and other

JavaScript library intended to simplify writing OOP in JavaScript which represents alternative JavaScript inheritance approach, provides support of JavaScript classes hierarhies, automatic resolving and optimizing external scripts files dependencies.

JSONER is a JavaScript library intented to simplify most used operations with JSON based on event API on JSON tree. It includes: data lookup and binding solution, HTML form by JSON dynamically creation and population, transformation and comparison JSONs.

LiMa means Lightweight Markup Language. It is a parser for an easy to use ASCII/Text-based markup - comparable to Markdown or the Wikipedia-Markup language with special configurable extensions in defining Links and image-resources.

NAC is a collection of tools for cryptography. The goal is to provide simple-to-use crypto tools (like an OTP, String and number generator, public key algorithm...) you can use under Linux, Windows...

This project intends to create an indexing search engine, for knowledge management. The primary object is to apply an information retrieval core. And implement a knowledge data discovery theory such as data mining algorithm, text mining.

Open Linux TSPL is a multiplatform (cross-platform) free software suite for software and web development. Open Linux TSPL helps developers create applications for Win32, Linux, Unix and Mac using one codebase. [Will be released: September, 2008]

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.

A P2P overlay construction toolkit, which supports routing algorithm researchers in addition to application developers. It provides multiple routing (DHT) algorithms such as Chord, Kademlia, Koorde, Pastry and Tapestry, and a distributed environment emu

Battle Code/Engine made in PHP and intended for browser games. Version 1.0-beta released after some testing. The homepage now links to the simulator available in the files.

This library allows you to generate a random number in the specified range from 0 to n, without using the built-in function Math.random (), and gets a random number from the processing time of polymorphic mathematical calculations, which depends on the current physical parameters of the CPU, RAM, and t .P. The resulting sequence corresponds to a discrete uniform distribution and is close to natural random sequences in terms of statistical randomness tests (LFSR, Approximate Entropy, DIEHARD Test).

The Rank Aggregation and Evaluation Suite is a comprehensive set of rank aggregation algorithms and performance measurement tools for use in research.

A fast way to rate the reading challenging level of book or text. Unlike well known reading metrics such as Fog, Kincaid, SMOG, ARI, Flesch, and Coleman-Liau readability this metric takes into account far more factors and is standarized against a corpus
