Free xboard 25 software for linux

CBoard (Curses/Console Board) is an Ncurses frontend to chess engines supporting the XBoard protocol.

CBoard is still in development, but has quite a few features that make it usable. Supports reading and writing PGN including roster tags, RAV, FEN, NAG and comments. The move validator still needs work though.

Kagiru is a Sudoku puzzle game supporting automatic puzzle generation, manual puzzle definition.

Kagiru also features automatic puzzle solving, multiple levels, puzzle loading and saving, puzzle progress, localization, and errors shown in play.

XLogo is known to work successfully with LINUX (Debian, Mandrake 9.*, SUSE 8.2)
XLogo is a Logo interpreter written in Java. This program is therefore free as in freedom and free as in beer.
Logo is a language developed in the 70s by Seymour Papert. It is an excellent language to begin learning programming with, and teaches the basics of things like loops, tests, procedures, etc.
The user is able to move an object called a "turtle" around the screen using commands as simple as forward, back, right, and so on. At each move, the turtle leaves a trail behind it, and it is therefore possible to create drawings. Operations on lists and words are also possible.
For example, forward 100 right 90 will make the turtle move 100 steps forward, and then turn the turtle 90° to the right.
This graphical approach makes Logo an ideal language for beginners, and especially easy for children!
Enhancements:
- Several bugs were fixed.

The FAAC project includes the AAC encoder FAAC and decoder FAAD2.
FAAC supports several MPEG-4 object types (LC, LTP, HE AAC, Main, PS) and file formats (raw AAC, MP4, ADTS AAC), multichannel and gapless en/decoding as well as MP4 metadata tags.
The codecs are compatible with standard-compliant audio applications using one or more of these profiles.
General FAAC compiling instructions:
1. Make sure you have autoconf, automake and libtool installed. For MP4 support, you must have libmp4v2 (included in faad2) installed.
2. cd to FAAC source dir
3. Run:
./bootstrap
./configure
make
make install
Usage:
faac [options]
Options:
-a X Set average bitrate to approximately X kbps per channel (i.e. using -a 64 averages at 128 kbps/stereo).
-c < bandwidth > Set the bandwidth in Hz (default value depends on sample rate)
-q < quality > Set quantizer quality (default: 100, averages at approx. 128 kbps VBR for a normal stereo input file at 16 bit and 44.1 kHz sample rate).
--tns Enable TNS coding.
--notns Disable TNS coding.
-n Disable mid/side coding.
-m X AAC MPEG version, X can be 2 or 4 (default: MPEG-2, so for the sake of interoperability with non-standard compliant players like QuickTime 6 you should set it to "4").
-o X AAC object type, X can be LC, MAIN or LTP (default: LC, for the same reason as with the MPEG version dont use Main or LTP).
-r RAW AAC output file (i.e. without ADTS headers).
-P Raw PCM input mode.
-R Raw PCM input sample rate in Hz (default: 44100 Hz).
-B Raw PCM input bit depth (default: 16 bits, also possible 8 bits).
-C Raw PCM input channels (default: 2).
- < stdin > If you simply use a hyphen/minus sign instead of an input file name, FAAC can encode directly from stdin, thus enabling piping within other applications like foobar2000 or mp4live.
Note: VBR output bitrate depends on -q AND -c, so you should only vary the default setting -q 100 -c 16000 if you know what youre doing and/or want to experiment with other cutoff frequencies at a given quality setting.
The ABR setting with -a is an approximate average bitrate that does not use a bit reservoir, i.e -a 64 and -q 100 at 44.1 kHz will result in exactly the same output file.
The following list should give some orientation for useful -q and -c settings, based on FAAC v1.17. The resulting VBR bitrates are referring to an average sounding stereo file with 16bit, 44.1 kHz, i.e. ct_reference.wav in this case. Multiplexing these AAC files to MP4 with e.g. mp4creator will result in a ~3 kbps lower bitrate because of the stripped ADTS headers:
-q 130 -c 22000 -m 4 (~218 kbps)
-q 120 -c 20000 -m 4 (~194 kbps)
-q 110 -c 18000 -m 4 (~158 kbps)
-q 100 -c 16000 -m 4 (~129 kbps)
-q 90 -c 14000 -m 4 (~103 kbps)
-q 80 -c 12000 -m 4 (~79 kbps)
-q 70 -c 10000 -m 4 (~62 kbps)
The added -m 4 switch does not change the bitrate or sound of course, but is recommended for most AAC/MP4 players that use an updated FAAD2-based plugin from this year (Winamp 2.x, foobar2000 etc.) or cant decode MPEG-2 AAC LC files like QuickTime 6. Philips Expanium users should not use this switch, because their CD portable does not know MPEG-4 AAC files.
Enhancements:
- Small bug fixes since last version

htb-stats.sh is a useful script for htb class summarization. htb-stats is designed to allow simple, non-root usage, e.g. "./htb-stats.sh eth0".
If an htb.init, tcng.init, or htb-gen configuration is found, it will label traffic output with information taken from respective configuration files.
Enhancements:
- support label-less , adapt to newer tcs backlog output

ePoll provides a Web-based poll written in server side Java.
ePoll is a Web-based poll written in server-side Java. It allows polls to be set up and administered. The content of the poll can be completely customized, and multiple-choice questions can have specific sets of answers. Statistics can be collected from the poll and reported on.
Main features:
- Voting and results viewing
- Multiple poll categories
- Multiple polling booths
- Polling booth security control
- Allows administrators to set up polls in the system and supply the set of opinions from which the user has to choose
- Allows administrators to configure the system to allow one vote per poll per user or multiple votes per user
- Allows users to register a vote on polls on the site
- Allows users to see the results of a vote broken down into total votes and number of votes for each option
- Allows users to list all polls running on the site
Enhancements:
- This release fixes many deprecations and compatibility with Expresso 5.6.
