Tomboy is an open source and free desktop notetaking application written in C++ for Windows, Linux, and BSD systems. As of current version (2.4 (released 2010/01), it supports image input and output, hyperlinks to the web, but currently not audio or video output. The program is available for free download from the official website, which will direct you to the download folder where you can save the software. Some people have reported issues with the Tomboy download process.
In addition to being free, tomboy is also considered to be an "open source" software. What this means is that the application is developed using the open source code that has been widely available for anyone willing to contribute. It allows you to take full advantage of the code's functions and capabilities without requiring any additional effort or cost. Although tomboy does have a few features that will require additional work such as support for multiple graphics formats, sound, and support for a Java servlet, it's primary focus is on simplicity and flexibility. This means that even those without any programming experience can easily use the application to create free applications and games.
To get started with Tomboy, just download the software, launch it up, and then follow the on-screen instructions to install the program and configure it for your OS. The basic installation process requires you to fill in some basic information about your hardware and settings, and then Tomboy will walk you through the rest of the process. Once the software is installed and configured, tomboy-ng should run and begin generating free applications. A list of all currently supported tomboy-ng version numbers can be found at the Tomboy website, and the list of supported languages should be updated accordingly.
