Integrated application development environment (IDE) in the programming languages Java, JavaFX, Ruby, Python, C++, PHP, JavaScript/HTML5, Groovy and several others. To support development for mobile platforms (J2ME), you must install the NetBeans Mobility Pack separately.

In terms of quality and capabilities, NetBeans IDE is not inferior to the best commercial (paid) integrated development environments, supporting refactoring, profiling, highlighting syntactic structures with color, autocompletion of typed structures on the fly, many predefined code templates, and more.

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.

OpenShot is a very easy-to-use video editor that anyone can understand. A large number of video and audio formats are supported, it is possible to insert transitions and use effects, both video (brightness, contrast, white balance, sepia, old film effect, etc.) and sound. It is possible to insert 3D titles created in Blender. The program easily integrates into the GNOME environment; files can be added to the project by simply dragging and dropping. Exporting files makes it easy to have ready-made profiles.

A MIDI file player/game that displays the musical notes AND teaches you how to play the piano.

PianoBooster is a fun way of playing along with a musical accompaniment and at the same time learning the basics of reading musical notation.
The difference between playing along to a CD or a standard MIDI file is that PianoBooster listens and reacts to what you are playing on a MIDI keyboard.

To run Piano Booster you need a MIDI Piano Keyboard and a MIDI interface for the PC. If you don't have a MIDI keyboard you can still try out PianoBooster, using the PC keyboard ('x' is middle C), but a MIDI piano is really recommended.

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.

MuseScore is a WYSIWYG editor with the ability to quickly enter notes from both the computer keyboard and an external MIDI keyboard. Supports import and export of data in MIDI, MusicXML, LilyPond formats, as well as import of files in MusE, Capella and Band-in-a-Box formats. In addition, the program can export scores to PDF, SVG and PNG files, or to LilyPond documents for further fine-tuning of the score.
