Free online keyboard trainer software for linux

Optimus OLED Keyboard Linux Driver project is intended to provide a generic linux driver for OLED-based hardware made by Art. Lebedev Studio.
The current goal is to support the Optimus Mini Three keyboard.
Main features:
- Uses libusb to communicate with device (no specific kernel driver needed)
- As the kernel-provided module for pl2303 didnt work in our case, we recoded the driver with libusb
- Uses libpng to read PNG images, and display them
- Detects when a button is pressed
- Implements OLED_PROTOCOL_SET_IMAGE, OLED_PROTOCOL_POWER_ON, OLED_PROTOCOL_POWER_OFF, OLED_PROTOCOL_SHOW_OLED, OLED_PROTOCOL_GET_IDCODE, OLED_PROTOCOL_SET_IDCODE, OLED_PROTOCOL_SET_BRIGHTNESS.
- Support for more than one OLED Mini Three connected to the same computer
- All USB code is in a static library
Enhancements:
- One of the most annoying bugs (auto-switch-off of the key display after five seconds) has been fixed.
- Functions similar to the ones provided by the original Win32 library for image color settings are also available, allowing you to set color temperature and gamma.
- Theres better support for input, using threads as libusb only provides a blocking way to read data (or some bytes are missed).

Score Reading Trainer helps you improve your (musical) score reading skills by practicing with random scores.
It works in a very simple way, you choose the clef, the key and the accidentals you want to practice as well as thee range of notes and then, the program generates a on-screen score with that parameters but randomizing the notes and the accidentals (and everything else that is randomizable).
The keys of the keyboard are mapped to the notes like in a piano (it would be nice to support midi in the future) and all you have to do, is press the right key for the first note you see in the score on the screen.
If you pressed the right key, the note will disapear and replaced by the second one, a diferent note, and you have to repeat the process.
As the notes are generated randomly, theres no way one can predict the following note and since several notes (as much as the screen allows) are on the screen, one can also train pre-reading (reading ahead of the current one) of the notes.
The program doesnt emit any sound (at least, yet) and its not inteded to teach rithmic or melodic concepts.

- Respect the position (over the third line) where notes are inverted.

- Limits wasnt really respected in other clefs than G2.

PingoS Tipptrainer project is a touch typing trainer that supports German and English keyboard layouts.

Because of many problems with wxGTK and GTK, this only works with wxGTK-2.4 and GTK-1.2 and a non-UTF-8 locale.

Typing Trainer is a software developed to exercise typing skills.
Typing Trainer is designed for exercising typing speed and typing accuracy, by providing an environment to type in a copy of an original text within a specific time period.
It also has the ability to store the results of such an exercise for exam purposes.
Enhancements:
- Some bugfixes in unicode handling, primarily in the way results are displayed.

Spam Trainer project makes it easier for GNOME users to train spam filtering software (e.g. SpamBayes or SpamAssassin) that "learns" how to tell the difference between real email (ham) and unsolicited messages (spam).

Not all email clients have spam filtering (and training) built in, and training external filtering programs can be fiddly.

Spam Trainer was written to provide easy (drag and drop) training from the Evolution mail client, and should work just as well with any email client that supports the drag and drop protocol implemented by the GTK+ toolkit.

CW Trainer is an easy-to-use CW trainer that is adaptable for both the Koch and Farnsworth method of learning CW.
CW Trainer can generate random tests or read text from a file. Sample QSOs are included.
Enhancements:
- Minor code changes were made to enable compilation with gcc 3.3.

Online Turnbased Wargame is a multi-user war game with multi-layer delegation. Logistics, production, and technology development is included. Creation of maps, scenarios, campaigns, Orders of Battle, and Tables of Equipment is also included in the scope
Enhancements:
- This release completes the move from a stand-alone application to being integrated as a plugin for the e107 CMS.
- Development will continue in this framework.
