User accounts and applications

Each Neuron system has three default user accounts with user interfaces optimized for different experience levels and needs. The accounts being: Lil_H4x0r, H4x0r_JR and L33t_H4x0r (as many as desired can be added).

The first, the Lil_H4x0r account is for the absolute beginner, has three login options. The user can log directly into the Gcompris early learning suite. The user can log into the Sugar Interface, or the user can log into a specially designed desktop interface.

The first login option is Gcompris.


GCompris is a collection of educational games that provides different activities for children aged 2 to 10. It is so comprehensive that even if it was the only app on the system it would still be worth the asking price. It currently offers in excess of 100 educational activities with more being developed, that teach children the following:

  • computer discovery: keyboard, mouse, different mouse gestures, …
  • arithmetic: table memory, enumeration, double entry table, mirror image, …
  • science: the canal lock, the water cycle, the submarine, electric circuit simulation …
  • geography: place the country on the map
  • games: chess, memory, connect 4, oware, sudoku …
  • reading: reading practice
  • other: learn to tell time, puzzle of famous paintings, vector drawing, cartoon making, …




The second option is to log directly into the Sugar interface, and experience what that project has to offer. Sugar, and it’s included activities is the entire system of the $100 One Laptop Per Child XO-1, on the Neuron it is just one of many possibilities. Sugar is a free and open source desktop environment designed with the goal of being used by children for interactive learning. Developed as part of the One Laptop per Child (OLPC) project, it is the default interface on OLPC XO-1 family of laptop computers. Sugar is a learning platform that reinvents how computers are used for education. Collaboration, reflection, and discovery are integrated directly into the user interface. Through Sugar’s clarity of design, children and teachers have the opportunity to use computers on their own terms. Students can reshape, reinvent, and reapply both software and content into powerful learning activities. Sugar’s focus on sharing, criticism, and exploration is grounded in the culture of free software. Unlike most other desktop environments, Sugar does not use the “desktop”, “folder” and “window” metaphors. Instead, Sugar’s default full-screen activities require users to focus on only one program at a time. Sugar implements a novel file-handling metaphor (the Journal), which automatically saves the user’s running program session and allows him or her to later use an interface to pull up their past works by date, activity used or file type.

  • Sugar facilitates sharing and collaboration.
    Children can write documents, share books and pictures, or make music together with ease.There are no files, folders, or applications.
    Children interact with Activities. Activities includes an application, data, and history of the interaction that can be used to resume and reflect on the child’s work .
  • Everything is saved automatically.
    It is our goal that you will never lose your work. Documents will eventually by synced with a network server, adding additional protection.
  • A Journal is used for accessing data.
    The Journal is a diary of things that you make and actions you take. It is a place to reflect upon your work.

KDE desktop


The third interface option at login is a highly customized KDE desktop that allows free exploration of age appropriate applications, without adult intervention. It sparks a child’s natural curiosity, promoting intrinsically motivated, self directed learning. This level consist of the following programs: Gcompris, Childsplay, Tux paint, Tux math, Pairs, Tux typing, Potato Guy, Tux racing games.



childsplay can be used at home, kindergartens and pre-schools. It’s a fun and save way to let young children use the computer and at the same time teach them a little math, letters of the alphabeth, spelling, eye-hand coordination etc.

  • memory activities that are fun to play and at the same time learn sounds, images, letters and numbers.
  • Fun activities that train the child to use the mouse and keyboard.
  • pure game activities like puzzles, pong, pacman and billiards.

Inkscape is an open-source vector graphics editor similar to Adobe Illustrator, Corel Draw, Freehand, or Xara X. What sets Inkscape apart is its use of Scalable Vector Graphics (SVG), an open XML-based W3C standard, as the native format. The design process may begin by doodles on a napkin, a sketched mind-map, a photo of a memorable object, or a mock-up in software which really wouldn’t work to complete the project.  Inkscape can take you from this stage to a final, professional-grade design format which is ready for publication on the web or in physical form.If you are new to the process of creating vector graphics it may feel different, but you will quickly be pleased by the flexibility, and power Inkscape offers. Vector design is often the preferred method of image creation for logos, illustrations and art which require high scalability. The Inkscape application is used across a wide variety of industries (marketing/branding, engineering/CAD, web graphics, cartooning) and individual uses.

Programming / Software Development

Along with having many popular development environments installable through the package manager/ ‘app store’. Neuron systems come with multiple child centric development  environments. The following development environments are installed, aimed at teaching programming concepts for diverse age groups:

Little Wizard


Little Wizard is a development environment for children. It is intended to be used by primary school children to learn about the main elements of real computer languages. Using only the mouse, children can explore programming concepts such as variables, expressions, loops, conditions, and logical blocks. Every element of the language is represented by an intuitive icon, making it easy to learn.



Squeak is a modern, open source, full-featured implementation of the powerful Smalltalk programming language and environment. Squeak is highly-portable, running on almost any platform you could name and you can really truly write once run anywhere. Squeak is the vehicle for a wide range of projects from multimedia applications and educational platforms to commercial web application development.



With Scratch, you can program your own interactive stories, games, and animations — and share your creations with others in the on-line community.Scratch helps young people learn to think creatively, reason systematically, and work collaboratively — essential skills for life in the 21st century. Scratch is a project of the Lifelong Kindergarten Group at the MIT Media Lab. It is provided free of charge.



Guido van Robot is a minimalistic programming language providing just enough syntax to help students learn the concepts of sequencing, conditional branching, looping and procedural abstraction. Its biggest strength is that it permits this learning in an environment that combines the thrill of problem-solving with instant visual feedback. In short, it is an interactive, introductory programming language that is excellent for learning the basic concepts of programming, applicable in any high-level language. Best of all, it’s a whole lot of fun, too!

Along with the child centric development environments the systems have the Arduino integrated development environment installed.
