GNU Operating System
The first and only free operating system developed to win user's freedom in their computing. Its mascot is an African animal wildebeest (a gnu). GNU is often found in a combination with the kernel, Linux, as a unity called GNU/Linux. GNU OS is consisted of multiple components with various licenses and most of them are licensed under GNU GPL. The origin of GPL license is of course GNU just like the name suggest.
Linux
The world most well known kernel with penguin logo is under GPL. It is the kernel of hundreds of operating systems, including Ubuntu and Android, that empowers almost all known computers from the smallest to the biggest ones, including smartphones and supercomputers.
GNU C Compiler
In computing field, a compiler is a program that translates software from its source code into binary code -- so the program is ready for the users. GNU C Compiler (GCC) is the most famous free compiler and all (or at least most of) GNU/Linux operating systems are produced with it. GCC is a part of GNU OS. It is licensed under GPL.
Plasma
KDE Plasma 5 is under GNU GPL. It is the user interface of Kubuntu operating system, as well as many other OSes.
GNOME
GNOME is under GNU GPL too. It is the official user interface of GNU Operating System, and its distributions like Ubuntu, as well as RHEL. The name GNOME was an abbreviation of GNU Network Object Model Environment.
Qt
In computing field, a software development kit (SDK) is a collection of everything that helps user to create software. Qt is a world class SDK, that is, the material that built Kubuntu, KDE Plasma, and also Telegram aside from so many other great software. Qt is licensed under GNU GPL.
OpenJDK
OpenJDK is a choice of Java libraries with free license that can be used to develop Java applications by software developers. It is the library that is used usually with Netbeans or Eclipse IDE. It is licensed under GPL.

Blender
Blender is a 3D modeler and animator, the world most successful free software on desktop. It had been used to produce 3D movies like Sintel and Tears of Steel as well as to draw real architectures (CAD). It is licensed under GPL.
Gimp, Inkscape and Scribus
GNU Image Manipulation Program (Gimp) is the GNU's Photoshop, the professional image editing program of free software. Inkscape (formerly Sodipodi) is illustrator and vector drawing program. It features RGB colors, international standard SVG and can read CorelDRAW's as well as AI's document formats. Scribus is a desktop publishing, page layout design program. The three of them are all GPL licensed and cross platform.

The infamous, orange colored audio video player that everyone use is also under GPL. It is an exemplary software for being cross platform -- it runs on all major OS including Android and iOS as well -- and truly popular too -- it counts 29 million downloads at the time this article being written.
Krita and MyPaint
Krita, the professional 2D digital painting and animation program and it is originally part of KDE. MyPaint is a free style 2D digital painting program. They are licensed under GPL.
GEDA, KiCAD and LibrePCB

Super Tux Kart
Just like penguin is often a symbol of GNU/Linux system, Super Tux Kart is the symbol of gaming on libre software community. It is a fun 3D racing game with characters representing our Libre Software like Gnu (GNU), Tux (Linux), Puffy (OpenBSD), and the others.
WordPress
The world infamous website software. If you know WordPress.com service, it runs with WordPress software inside. With it, one and an organization may create their own website quickly, beautifully, and with full customization. WordPress is licensed under GNU GPL, but not only that, as all thousands Plugins and Themes distributed are licensed under GNU GPL too.
How To Install
For the applications mentioned above, you can install them on Ubuntu by pressing Enter after typing this command line accordingly.

For other application, change gcc into one of these instead:
- OpenJDK: default-jdk
- GNU R: r-base
- Blender: blender
- GIMP: gimp
- Inkscape: inskcape
- Scribus: scribus
- Super Tux Kart: supertuxkart
- VLC: vlc
- Krita: krita
- MyPaint: mypaint
- GEDA: geda
- KiCAD: kicad
Follow these tutorials to install Telegram, LibrePCB, and WordPress.
For either GNOME or KDE, we suggest you to not install either one on top of existing OS, but you better use Ubuntu if you want GNOME, use Kubuntu if you want KDE.
Afterword
That's all. Actually, there are too many other software not mentioned above deliberately to invite everyone to seek more themselves or not deliberately because I didn't know of them yet. All in all, I hope this list encourages everyone and all to love Libre Software and distribute them more to the others. Let's share once again!
