U++ is a cross-platform rapid application development environment in C++. Can work with GCC, Clang, MinGW and Visual C++ and contains a full-featured debugger.
Fast development comes from smart and aggressive use of C++, not fancy code generators. In this regard, U++ competes with popular scripting languages while retaining the runtime characteristics of C/C++.
The development environment includes BLITZ build technology for up to 4x faster C++ rebuilds, visual designers for U++ libraries, Topic++ for documenting code and creating rich text resources for applications (such as help and code documentation), and Assist++, a powerful C++ code analyzer , which provides features such as code completion, navigation, and transformation.

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.

VokoscreenNG can be used to record videos from computers screen, webcams, external cameras, etc. This graphical tool can produce educational videos, live recordings of browser navigation, tutorials of installations, record videoconferences, etc. You can capture an alone video or video and sound.

This program can save files in some formats and use some codecs for video and audio:
- Video: x264, openh264, H.264 (Intel GPU), MPEG-2 (Intel GPU) and VP8.
- Audio: vorbis, flac, opus, mp3 and aac.
- File : mkv, webm, avi, mp4 and mov.

CodeLite is a powerful and lightweight IDE specializing in C, C++, PHP and Javascript.

Its features include:
* Generic support for compilers
* Built-in GDB support
* Database-based Code Completion mechanism
* Syntax highlighting for C/C++, Java, Perl, XML, Makefile, Lua, Diff files, PHP, JavaScript, Python, HTML, and ASP
* Text Folding
* doxygen comment generator.

Integrated development environment for the Python language. It includes a graphical debugger that supports interactive exploration while suspended and auto-stopping on critical exceptions.
Main features:
- Project Manager;
- Editor with syntax highlighting;
- Debugger, profiler;
- Run Python code with support for command line parameters;
- Unit testing;
- Console for output and task manager (self-renewing TODO sheet).

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

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.

Kdenlive is a non-linear video editor that supports DV, HDV and many other formats.
Its main features:
✔guides and markers for organizing the editing table
✔copy and paste clips, effects and transitions
✔changes in real time
✔video capture via FireWire and Video4Linux
✔screen capture
✔export to any FFMPEG supported format

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.
