SFX Creator
This program creates a very high secure AES /Serpent/Twofish 256 bit/Blowfish 448 Bit, Mars 1248 Bit and RC6 2048 Bit selfextracting file. The SFX-Header is 41kb-49kb great. This SFX cipher checks whether the decrypting password is correct with a highly secure method, never compromising the key: while a 64 byte random number is created and also encrypted. While decrypting these two numbers are compared to test for the correctness of the password. Very simple, yet as safe as the algorithm itself. The license covers Multicrypt too. One license for two programs.

Epic24
From the site: Epic24 is a GUI program that I wrote to interactively compare graphic compression codecs against each other. It currently contains JPG, Lossless JPG, JPEG 2000, (Jasper Library Implementation), PNG, John Robinson’s BTP and ATP, and finally my own lossless graphics compression called IMPLODE (IMage Predictive LOssless Decoder Encoder).

APT
APT (Adaptive Prediction Trees) image coding supersedes BTPC (Binary Tree Predictive Coding). It is a general-purpose compression scheme for all types of still image. It does both lossless and lossy compression of monochrome and color images from 1 to 16 bits per component. Its performance on all image types is often close to that of the best alternative.

WinHki
WinHki is an archiving tool that understands the usual gamut of formats - compresses 9, decompresses 12, and one of this is its own proprietary HKI format.

OutlookZIP
The OutlookZIP it’s an Add-On for Microsoft® Outlook. It makes easy for you to compress the files that you attach to Microsoft® Outlook e-mail messages. OutlookZIP adds three buttons to Outlook toolbar making the usage simple easy. OutlookZIP works only with Outlook 2000, Outlook XP (2002), and Outlook 2003. It does not work with Outlook Express.
Full-Text Searching & the Burrows-Wheeler Transform
In this article, I examine an indexing method that lets you find any character sequence in the source text in time only proportional to the sequence length using a structure that can compress the entire source text and index into less space than the text alone. This technique is exceptionally fast at detecting and counting occurrences of any string in the source text.

Zip and Unzip Using VB5 or VB6
This code shows how to use the freeware InfoZip Zip32.DLL and Unzip32.DLL files from the http://www.cdrom.com/pub/infozip/ website. The InfoZip DLL’s are open-source DLL’s that are available for programmers to utilise free of charge. They are standard C DLLs and were very tricky/impossible to interface with VB until VB5/6 offered the ‘addressof’ operator.

Replacing a Dictionary with a Square Root
The OpenH323 Project
This open source project aims to create a free H.323 stack. The project was started as a reaction to the high cost of commercial implementations of audio and video compression code implementing the various components of H.323. Roger H. adds There are now several useful applications which use the library
including OpenMCU (a reliable multi person conference server)
and GnomeMeeting (a GTK/Gnome GUI client for Linux/BSD Unix.
Version 1.13.13 of OpenH323 shipped in Marh, 2004.

ComPacketer
The folks at Compandent have this to say about their product: Compandent’s ComPacketer is a voice coder which achieves a breakthrough in quality/bit rate/complexity tradeoff. Compandent’s novel technology, the ComPacketer that operates at 2.8 kb/s, produces speech with quality which exceeds that of ITU-T G.723.1 at 6.3 kb/s. Using the ComPacketer, only graceful degradation is introduced in frame erasure environment, as compared to the higher quality degradation introduces by the common standards used for VoIP.
