FlameRobin is a GUI tool for administering the Firebird database management system
Her goals:
- undemanding to resources (low memory consumption, fast operation)
- cross-platform (Linux, Windows for starters, support for other systems is planned)
- dependence only on other free software

Scratch is a simple, interactive, collaborative software development environment for creating interactive stories, animations, games, music, and graphics—and publishing them on the Internet. Scratch is designed to help children (ages 8 and up) implement 21st century educational skills. As they create Scratch projects, children learn important math and computer concepts and gain a deeper understanding of the design process.

KTurtle is an educational programming environment that uses the TurtleScript programming language (inspired by the logo) to make programming as easy and accessible as possible.
The user issues TurtleScript language commands to control the "turtle" as it draws on the canvas, making KTurtle suitable for teaching basic math, geometry, and programming

KuMir (Set of Educational WORLDS) is a programming system designed to support initial computer science and programming courses in secondary and high schools.
Peculiarities:
✔ The KuMir system uses a school algorithmic language with Russian vocabulary and built-in executors Robot and Draftsman;
✔ When entering a program, KuMir carries out constant full control of its correctness, reporting in the fields of the program about all detected errors;
✔ When executing a program in step-by-step mode, KuMir displays the results of assignment operations and the values of logical expressions in the fields. This allows you to speed up the process of mastering the basics of programming.

wxMEdit can edit files in Text/Column/Hex modes, and supports many useful features such as bookmarks, syntax highlighting, conversion to other encodings, word wrapping, word counting, and checking for updates.
It supports all major encodings (UTF8/16/32, ISO-8859-x, CP125x, KOI8, GB18030, Big5, ...) not only in Text/Column mode but also in Hexadecimal (Hex) mode.

Denemo is a program designed to prepare sheet music for further processing and publication using LilyPond.
This is not a WYSIWYG music editor; its task is to quickly type notes, without displaying them correctly. Almost all input functions are implemented using hot keys, which actually speeds up the typing process, according to the developers. Some keyboard commands are the same as the corresponding commands in the Lilypond syntax: for example, moving the cursor or note an octave up and down is done with the keys ' and, respectively, the beginning and end of a phrasing line - ( and ), etc. Command overrides are available, so the user can customize the environment completely for yourself.
Denemo has different operating modes: insertion modes (normal and classic, which differ in the order of keystrokes when entering notes) and editing. Also, any operation can be performed with the mouse and recognition of their recorded sound, giving musicians a more familiar input method.
By saving scores in the LilyPond format and further editing the resulting source file, you can improve the appearance. It is possible to export scores in ABC music notation format and create MIDI files.

This is an alternative to commercial programs like FL Studio (R), which allow you to create music on your computer.
It includes creating melodies and beats, synthesizing and mixing sounds, and organizing samples.
You can have fun with the MIDI keyboard and much more, all in a convenient and modern interface.

Shotcut supports many video, audio and image formats thanks to FFmpeg.
It uses a timeline for non-linear editing of multiple tracks, which can consist of different file formats.
