Software Implementing Arithmetic Coding
Links to code and papers by Radford Neal and pals.
Radford Neal’s Home Page
Radford Neal is a professor at the University of Toronto. One of his research interests is data compression, and his name appears on a couple of seminal papers on arithmetic coding. Links to papers can be found here.
ARJ Software, Inc.
The home page for Robert Jung and ARJ. This page has links to the ARJ FAQ, downloads of the various ARJ executables, and ordering information. It also is the home page for the newer JAR archiver. Arj is now on release 2.71.
Alex Vinokur Newgroup Posts
Alex has collected a series of newsgroup discussions on Huffman coding.
n-ary Huffman Template Algorithm
Some C++ template code implementing a Huffman algorithm by Alex Vinokur.

RAR 2.70
This site appears to have a massive number of links to the current versions of RAR. The entire site is written in Dutch.
Bzip2 mini-HOWTO
David Fetter wrote a Linux howto telling you how to compile, install, and use bzip2, the BWT-based freeware archiver.
Ultimate ZIP Cracker
A program designed to crack lost passwords for zip and arj files.
FMA&H
This page is a mystery to me.

Collake Software - JCALG1
Home of JCALG1, an LZSS derived lossless compression algorithm with full x86 32bit assembly source. Data Compressioni Library user comment: I found LZSS C source and an EXE. The EXE was useful for testing. I expect to use this in an embedded app after further research..
Ascent Solutions, Inc.
ASCENT SOLUTIONS Inc. PKZIP data compression software for MVS (mainframe), Windows (Netzip), VM, VSA, AS/400, UNIX, OS/2, DOS, VMS. All products are 100% cross-platform compatible.
EnZip 3.0
EnZip is a freeware Windows compression program. Release 3.0 seems to have shipped in June of 2000, no activity since then.
WinArj
A version of Arj written specifically for 32 bit Windows. From Robert Jung, the author of the ARJ archiver.
HTML Compressor
A program that mungs HTML files in order to make them smaller. Some safe optimizations, some unsafe. Not really compression so much as optimization. Note: I’ve classified this as non-commercial, because the web site makes no mention of any kind regarding payment. I might be wrong.
AltaVista Compression Links

Smoothing DCT Compression Artifacts
A paper from SID Digest by Ahumada, A. J., Jr.and Rensheng Horng. Getting rid of those annoying DCT artifacts is obviously a big deal for those of you using JPEG and MPEG compression.
Perceptual Optimization of DCT Color Quantization Matrices
A paper by Andrew Watson from NASA Ames Research Center. This paper describes a procedure called DCTune which is claimed to create DCT quantization matrices superior to the default ones used in the JPEG algorithm.
Image Compression Using the Discrete Cosine Transfer
This paper from the Mathematica Journal gives some introductory material on using Mathematica to do a bit of image compression.
An Algorithm for Online Data Compression
The code from an article from by Sergey Ignatchenko from the October 1998 C User’s Journal. (see ignatch.zip)
Random Access Data Compression
Source code from Random Access Data Compression, by Philip Gage (see gage.zip) from the Septeber 1997 C User’s Journal
The Fast Lifting Wavelet Transform
Paper by C. Valens describing this algorithm which is frequently used in wavelet based data compression algorithms.

Some reflection on the death of Phil Katz
Phil Katz Legal Troubles
Near the end of 1999, Phil Katz showed up on a list of outstanding warrants in Ozaukee County, Wisconsin.
rfc1661 - The Point To Point Protocol
The description of the point to point protocol, which of course includes a little tiny bit on compression, since you can specify compression in a packet header.
