Free flac 1.01 software for linux

FLAC is Free Lossless Audio Codec. Grossly oversimplified, FLAC is similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality.
This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see supported devices) just like you would an MP3 file.
FLAC is freely available and supported on most operating systems, including Windows, "unix" (Linux, *BSD, Solaris, OS X, IRIX), BeOS, OS/2, and Amiga. There are build systems for autotools, MSVC, Watcom C, and Project Builder.
The FLAC project consists of:
the stream format
reference encoders and decoders in library form
flac, a command-line program to encode and decode FLAC files
metaflac, a command-line metadata editor for FLAC files
input plugins for various music players
When we say that FLAC is "Free" it means more than just that it is available at no cost. It means that the specification of the format is fully open to the public to be used for any purpose (the FLAC project reserves the right to set the FLAC specification and certify compliance), and that neither the FLAC format nor any of the implemented encoding/decoding methods are covered by any known patent. It also means that all the source code is available under open-source licenses. It is the first truly open and free lossless audio format.
Main features:
- Lossless: The encoding of audio (PCM) data incurs no loss of information, and the decoded audio is bit-for-bit identical to what went into the encoder. Each frame contains a 16-bit CRC of the frame data for detecting transmission errors. The integrity of the audio data is further insured by storing an MD5 signature of the original unencoded audio data in the file header, which can be compared against later during decoding or testing.
- Fast: FLAC is asymmetric in favor of decode speed. Decoding requires only integer arithmetic, and is much less compute-intensive than for most perceptual codecs. Real-time decode performance is easily achievable on even modest hardware.
- Hardware support: Because of FLACs free reference implementation and low decoding complexity, FLAC is currently the only lossless codec that has any kind of hardware support.
- Streamable: Each FLAC frame contains enough data to decode that frame. FLAC does not even rely on previous or following frames. FLAC uses sync codes and CRCs (similar to MPEG and other formats), which, along with framing, allow decoders to pick up in the middle of a stream with a minimum of delay.
- Seekable: FLAC supports fast sample-accurate seeking. Not only is this useful for playback, it makes FLAC files suitable for use in editing applications.
- Flexible metadata: New metadata blocks can be defined and implemented in future versions of FLAC without breaking older streams or decoders. Currently there are metadata types for tags, cue sheets, and seek tables. Applications can write their own APPLICATION metadata once they register an ID
- Suitable for archiving: FLAC is an open format, and there is no generation loss if you need to convert your data to another format in the future. In addition to the frame CRCs and MD5 signature, flac has a verify option that decodes the encoded stream in parallel with the encoding process and compares the result to the original, aborting with an error if there is a mismatch.
- Convenient CD archiving: FLAC has a "cue sheet" metadata block for storing a CD table of contents and all track and index points. For instance, you can rip a CD to a single file, then import the CDs extracted cue sheet while encoding to yield a single file representation of the entire CD. If your original CD is damaged, the cue sheet can be exported later in order to burn an exact copy.
- Error resistant: Because of FLACs framing, stream errors limit the damage to the frame in which the error occurred, typically a small fraction of a second worth of data. Contrast this with some other lossless codecs, in which a single error destroys the remainder of the stream.
What FLAC is not:
- Lossy. FLAC is intended for lossless compression only, as there are many good lossy formats already, such as Vorbis, MPC, and MP3 (see LAME for an excellent open-source implementation).
- SDMI compliant, et cetera. There is no intention to support any methods of copy protection, which are, for all practical purposes, a complete waste of bits. (Another way to look at it is that since copy protection is futile, it really carries no information, so you might say FLAC already losslessly compresses all possible copy protection information down to zero bits!) Of course, we cant stop what some misguided person does with proprietary metadata blocks, but then again, non-proprietary decoders will skip them anyway.

MACTS project is a traffic shaper that uses MAC addresses which are associated with users to classify traffic.
This allows fair usage of bandwidth among many machines. Additionally, there is a statistics monitor which displays current statistics on the terminal or stores them in round robin databases.
The stored data may then be used to generate graphs with the included Perl/CGI scripts. The configuration file is straight-forward and requires little knowledge of networking or the underlying traffic control mechanism. Setup should be easy.
Components:
macts - This clears the current traffic classifiers and sets up new ones, as directed by /etc/macts/macts.conf. It also stores some temporary state data in /etc/macts/handles.cache.
macts-stats - With no args, this displays statistics on a terminal, including data rate (kb/s), packet rate (packets/s), and backlog (packets) for each machine. Given the -r flag, it stores the statistics in round robin databases (one for each machine), located in /etc/macts/stats/.
macts-chart - This is a CLI chart generator which reads data from RRDs stored in /etc/macts/stats/.
macts-chart.cgi - This is a CGI wrapper for macts-chart.
Installation:
- mkdir /etc/macts
- mkdir /etc/macts/stats
- create /etc/macts/macts.conf
- add the following lines to /etc/sysctl.conf:
net.ipv4.conf.default.accept_source_route = 1 # is this necessary?
net.bridge.bridge-nf-filter-vlan-tagged = 0
net.bridge.bridge-nf-call-ip6tables = 0
net.bridge.bridge-nf-call-iptables = 0
net.bridge.bridge-nf-call-arptables = 0
- move macts, macts-stats, and macts-chart to /usr/local/bin/.
- (optional) install rrdtools and the perl rrdtool interface
- (optional) add the following line to roots cron:
*/5 * * * * /usr/local/bin/macts-stats -r 2&> /dev/null
- (optional) move macts-chart.cgi to your web servers cgi directory.
Enhancements:
- Installation instructions have been fixed.

Mcube project is a 4x4x4 Rubiks Cube solver.
Mcube solves 4x4x4 Rubiks Cubes. It is platform independent and supports both a pipable console-only format and a graphical format.
CGI version:
First finished release of mcube Solves 4x4x4 rubiks cube via a CGI web-based environment. The cube class can be used in other programs as well.
Command-line version:
This is the command-line version of the 4x4x4 solver. The algorithm is identical to the normal (CGI) version. Use this if you like do-it-yourself console programs.
Enhancements:
- Fixed concise() bug not updating mov[] correctly.
- Added "input page" generator on output page, for easier debugging.

When an image is taken from a video capture source (f.i. a freeze-frame), sometimes only either the odd or the even fields in the frame get captured, resulting in an image which, line by line, is data-black-data-black-etc.

De-interlace plug-in does a simple interpolation between the odd or even fields in an image to correct this.
