Free keyboard 1.0 software for linux

Klavaro application is just another free touch typing tutor program. We felt like to do it because we became frustrated with the other options, which relied mostly on some few specific keyboards.
Klavaro intends to be keyboard and language independent, saving memory and time (and money).
Main features:
- Internationalization: English, Esperanto and Portuguese. If you want to translate to another language, please read the instructions for translation.
- Ready to use keyboard layouts:
- "qwerty" (BR; BR_abnt0; BR_abnt2; IT; PT; US)
- dvorak (US)
- "qwertz" (HU)
- "azerty" (FR)
- Keyboard layout editor: makes possible to configure the keys positions and to save the result in a simple text file. If your keyboard isnt shown above, you can create it. If you need to do it, please let us know about.
- Basic course: a basic type of course is available for memorizing the keys positions on the keyboard. It is supposed to be independent from keyboard layout, by the generation of random character sequences to be followed by the student.
- Adaptability exercises: these exercises use all the keys ramdonly, so that you can practice using all the keyboard. Its named adaptability exercise because it develops the capacity to adapt your typing skills to any kind of strange words that may appear in some texts.
- Velocity exercises: one achieves velocity on typing when the environment is well known, or, when the words come from ones own language. Thats why these exercises focus on velocity. And even if your language isnt supported by the application, you still can indicate texts in any language to include the words contained there.
- Fluidness exercises: with these exercises, one works typing complete paragraphs, with good sense sentences. Typing errors arent accepted: the user must correct them with the backspace key before be allowed to go on. Especial attention is given to the typing rhythm, which must be as uniform as possible. Just like the velocity exercises, this one here makes possible to load any text files, independently of language.
- Progress charts: at the accomplishment of each exercise, some characteristics of your performance are saved and can be graphically showed. Thus, you can easily observe your learning progress (or regress).
- Clean graphical interface: when learning to type correctly, one must not get the attention off the exercises. So, it isnt recommended neither to have dozens of gauges measuring velocity, errors, time, etc; nor a virtual keyboard floating in front of the student: he/she must memorize the key positions by the tact, not visually. Hence, Klavaros interface started simple and will remain like that for all of its lifetime.
Enhancements:
- A Dutch translation was added.
- Turkish keyboard layouts were added.
- Size is now limited for loading personal text files in velocity and fluidness exercises, avoiding program freezings and/or segmentation faults.
- Interpretation of the environment variable LANGUAGE was corrected.
- Some code cleanup was done.

Veejay is a visual instrument and realtime video sampler. Veejay allows you to "play" the video like you would play a piano. While playing, you can record the resulting video directly to disk (video sampling). Veejay can be operated live by using the keyboard (which is 100% user definable) and / or remotely over ethernet.
Veejay can be used to manipulate video in a realtime environment i.e. VeeJay for visual performances or for (automated) interactive video installations.
Main features:
- Client/Server architecture
- Soft Realtime
- Native YUV processing
- Frame accurate
- Loop based editing (always playing)
- Non destructive editing
- Trickplay (scratch, marker, speed, direction)
- Mix your videos in the FX chain
- 126 built-in effects incl. luma , chroma key,
- Effect parameter animation
- Support for FreeFrame and Frei0r
- Support for truetype fonts
- Audio playback through Jack
- Audio rendering
- Load Quicktime, AVI and rawdv movie files
- Video output to SDL, OpenGL
- Full support for DV and MJPEG
- Live clip loading
- Live harddisk recording
- Live sample sequencing
- Live text
- Live camera(s) support
- Can stream over the network
- Deck save/restore
- Crash Recovery
- Dynamic output framerate
- Support for Open Sound Control
- Support for pure-data through sendVIMS external
- Free Software (GNU GPL)

SnakeMe project is a very customizable snake game.
SnakeMe is a beautiful and funny snake game. You can play alone, with up to three friends (two players on the keyboard, and two joypads), or against computer "intelligence" (eight players maximum).
You have also the choice between many snakes and levels, and you can even download more, or design your own ones.
Main features:
- A lot of fun!
- More than 10 different snakes. (1)
- More than 10 amazing levels. (1)
- More than 5 level themes. (1)
- Up to 4 human players: two on the keyboard, and two on the joypads, if there are any.
- Up to 8 players in a game, so there can for instance be two human players and six computer players.

X-Unikey project lets you type Vietnamese in X Window environment. X-Unikey is Unikey ported to Linux and FreeBSD.
It has been tested with many popular programs, such as OpenOffice, emacs, vim, QT applications, GTK applications... X-Unikey has all the features of the Windows version, except that its GUI is still too simplified.
All options are set through configuration file or keyboard shortcuts.
Enhancements:
- This release was unified with Unikey.
- Some bugs were fixed, including an array out of range error in macro matching that caused the engine to crash.
- Some unused options were removed.

KMouth is a KDE program which enables persons that cannot speak to let their computer speak, e.g. mutal people or people who have lost their voice.
Currently KMouth has an input field into which the user can type the phrases he wants to hear. Additionally the program contains a history of spoken phrases, a phrase book and word completion.
The user can select phrases from the history which he wants to be re-spoken or he can decide to put often used phrases into the phrases, so that they can be spoken with only few mouse clicks.
KMouth itself does not contain a speech synthesizer. Instead it assumes that a speech synthesizer is available in the system. Currently it either uses any shell command specified by the user or the the text-to-speech interface of KTTSD. (KTTSD, the KDE Text-To-Speech Daemon, a plug-in based KDE project that wants to provide both a standard text-to-speech interface for KDE applications and a simple-to-use configuration dialog for the user.)
Main features:
- An edit field into which you can type phrases you want to hear
- Word completion
- A history of spoken sentences from which you can select phrases which you want to be re-spoken
- A phrase book from which you can select regularly used phrases. The edit dialog for the phrase book allows you to:
- Add, edit or delete phrases and sub-phrase-books
- Assign keyboard shortcuts for phrases
- Import and export phrases and sub-phrase-books
- Import sub-phrase-books from a collection of standard-phrase books
- A configuration dialog which allows you to specify:
- The command for speaking texts
- The method of sending the text to the command (parameter or standard input)
- The character encoding for the text
- KMouth is licensed under the GNU General Public License.

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).
