- Dr. Geo, design & manipulate interactive geometric sketches with constraints. Dr. Geo aim is to be an open, easy to study, modify and extend interactive geometry software. It is distributed with its source code you can modify while using it. Ten years old kids use Dr. Geo to explore Euclidean geometric sketch, agile kids extend and program it with its embedded dynamic Smalltalk language and user interface.
- Fire★ is a a simple platform for decentralized communication and computation. Provides a simple application platform for developing p2p applications and share these applications with others in a chat like user interface. You don't send a message to someone, you send an program, which can have rich content. All programs are wired up together automatically providing distributed communication, either through text, images, or games. The source code to all applications is available immediately to instantly clone and modify.
- Free Oberon
- Free Oberon is a cross-platform IDE for development in Oberon programming language made in the classical FreePascal-like pseudo-graphic style. Compilation of user-written programs is performed using the Vishap Oberon Compiler and then GCC. The compiled console programs can be run in the built-in terminal emulator.
- The GNU C Reference Manual is strictly a reference, not a tutorial. Its aim is to cover every linguistic construct in GNU C, but not the library functions which are documented in The GNU C Library Reference Manual.
- Guido von Robot
- Guido van Robot (GvR) is a minimalistic programming language that provides 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.
- Harvest is a web application that provides a browsable directory of easy-to-start opportunities to contribute to a project such as translation, testing, or development. It is used by Ubuntu.
- Java Training wheels (J.T.W.) provides a less steep learning curve for learning to program in Java. The system is powered by a preprocessor that adds features to Java such as a superfor macro and a file inclusion system much like the C language's preprocessor.
- Khan exercises
- Khan Academy has created a generic framework for building exercises. This framework, together with the exercises themselves, can be used completely independently of the Khan Academy application.
The framework exists in two components:
- An HTML markup for specifying exercises.
- A jQuery plugin for generating a usable, interactive, exercise from the HTML markup.
Using the Framework Locally
You need to serve the files from some sort of a server. You can't just open the files directly in a browser. For example:
cd khan-exercises python -m SimpleHTTPServer
cd khan-exercises python3 -m http.server
Now if you open your browser to `http://localhost:8000` (or `http://127.0.0.1:8000/`) you should see the contents of the `khan-exercises` directory. Navigate to the `exercises` subfolder, and an HTML file under there to see an exercise.
The process for writing exercises is rather well documented. More information about this process can be found in the Khan Exercises wiki. Specifically:
- Have fun and make games, or hack your homework using Ruby! Just tell your parents or teachers you're learning Ruby programming... ;)
