Free keyboard practice 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).

KeyFrog is a tool for generating keyboard usage statistics. User obtains many informations about his activity: how intensive was his keyboard usage, how was it distributed in time, etc.

This project can be very useful to developers. The project is under fast development, first releases comming soon.

GNOME Advanced Preferences is an UI to tweak advanced GNOME preferences.

GNOME Advanced Preferences allows you to tweak hidden GNOME preferences, including custom keyboard shortcuts to execute specific commands, etc.

Stuff generally only available through GConf.

Midirecord is a simple command-line application to record a MIDI file with your MIDI keyboard.

Midirecord project also features automatic recording to a MIDI file when you play electric piano, and thus it may be used as a "recording daemon".

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.

Password Hasher enables a good security practice.
What good security practice demands:
- Strong passwords that are hard to guess.
- Different passwords at each site.
- Periodically changing existing passwords.
Why you probably arent practicing good security:
- Strong passwords are difficult to remember.
- Juggling a multitude of passwords is a pain.
- Updating passwords compounds the memorization problem.
Main features:
- Automatically generates strong passwords.
- One master key produces different passwords at many sites.
- Quickly upgrade passwords by "bumping" the site tag.
- Upgrade a master key without updating all sites at once.
- Supports different length passwords.
- Supports special requirements, such as digits and punctuation.
- Supports restricting a hash word to not use special characters. (New!)
- Saves all data to the browsers secure password database.
- Generates a portable HTML page with your site tags and option settings that allows you to generate your hash words in any browser on any machine without the extension installed. (New!)
- Can add marker buttons to unmask passwords on any web site. (New!)
- Extremely simple to use!
