NOTE! We have moved to https://gitlab.com/msc-generator/msc-generator All development happens there. Also, download new releases & submit issues there. A tool to draw various charts from textual descriptions. Currently, three types of charts are supported: Message Sequence Charts, generic Graphs, and Block Diagrams, with more to be added in the future. There is a command-line version for Linux and Mac (replacing mscgen), which now sports a GUI, as well. Msc-generator allows fine control over the appearance and has a rich feature set complete with detailed documentation. On Windows, you can embed the charts in a document or presentation and simply double-click it in Office to edit them. On Linux and the Mac, a command-line version is available, and a GUI, as well. A .deb package is available starting from Debian Bookworm (currently testing) and Ubuntu Jammy Jellyfish (22.04) from the official repositories. For older releases see the Wiki. A Mac homebrew package is available.

Kokua is an open source metaverse viewer project based on the Second Life Viewer source. Disclaimer: This software is not provided or supported by Linden Lab, the makers of Second Life.

Two experimental AI languages - Perkun and its successor Wlodkowic. Attempt to maximize the expected value of the payoff function by appropriate choosing the actions (output variables values). The package contains also a tool called zubr - a Java code generator based on Perkun. Take also a look at my blog: http://pawel-biernacki.blogspot.fi/ For Windows users there is an installer: http://www.pawelbiernacki.net/perkun.msi

amilab is a tool for image processing that includes its own scripting language, and an interface for visualizing 2d/3d images and 3d surfaces. Its main application is medical image processing.

AVInfo is a program that reports on multimedia files. It recognizes the following file formats: AVI, MKV, MPEG, MP3, OGM, IFO (DVD), and the subtitle files. AVInfo can be used in batch mode with file lists as well as with single files.

It is user-extensible, and newer versions (6.x) support advanced features such as GUI dialogs, through close client-server cooperation with Trebuchet or other clients that support MCP-GUI.

GRAMophone is an algorithmic generator of music composition. The music is generated using two kinds of formal grammar: Chomsky’s grammar for TOP DOWN approach to the composition and a reduced version of Lindenmayer grammar for BOTTOM UP approach.

The Green Engine was designed as an introduction to programming and game development for those who have little or no previous experience. The games developed using this system are described in a high level, simple to use scripting language.

March 2013 this project was announced first to public, but the feedback was ZERO. So I guess it is insanely bad and unusable. Ok. But sorry, I decided to continue it for myself to improve my inability and unexperience in software development FOR MYSELF. Even if it seemed to be the worst thing ever, I *NEED* to develop software for my own well being and even if I apparently - after over 20 years since the first lines of code I wrote - I improved my ability not a single bit than it is like that and I can't change it. BTW: there was feedback indeed: from the own 'family': "it is done by YOU so it cannot be of use for anybody!" (Literally: it contains algorithms and algorithms are evil and are non-existent in usable software)
