Fast MD5 Implementation in Java is a heavily optimized implementation of the MD5 hashing algorithm written in Java.
Fast MD5 Implementation in Java includes an optional native method for even greater speed improvements.
How Fast Is It?
Short answer:Much faster than any other Java implementation that I have tested and (surprisingly) even faster than the native, non-Java MD5 implementation on some systems.
Long answer:First of all, it is important to note that the term "fast" is used here in relative terms. The implementation of the MD5 message digest algorithm available on this page is written in Java and is fast compared with other implementations written in Java, both because it is heavily optimized by itself and because there is an optional native method that makes it even faster when the platform supports it. How it compares to a sensible implementation written in a language, such as C, that is compiled directly to machine code, is heavily dependent upon how good of a job the JIT compiler in your JVM does in compiling the code or whether you are able to use the optional native method.
Enhancements:
- Martin West contributed a bug fix and some code refactoring to make all targets work out of the box in the Ant build file. Previously, the "dist" target did not work if the "docs" directory was not present.

Objective Modula-2 programming language is a hybrid between Smalltalk and Modula-2 based on the object model and runtime of Objective-C.
The design is an example how native Cocoa/GNUstep support can be added to static imperative programming languages without implementing a bridge.
Objective Modula-2s scope encompasses the design of the Objective Modula-2 programming language and the implementation of a compiler to implement it. The initial compiler will generate Objective-C source code.
Enhancements:
- This code is used to verify ideas and concepts which come up in the course of defining the language.
- It is in an early stage, incomplete and subject to frequent changes.

Bellagio is a sample implementation of OpenMAX IL for Linux.
It enables software developers and ISVs to familiarize themselves with the OpenMAX IL API and to develop their own OpenMAX multimedia and streaming media components for mobile devices, including codecs, video I/O, and audio mixers.
Included sample components comply with the OpenMAX base and interoperability profiles and can be tunnelled together.
Main features:
- a shared library with the IL core and a "reference" OpenMAX component
- a number of OpenMAX components which pass Khronos conformance tests
- a set of GStreamer plugins that use the IL API (not available yet)
Enhancements:
New video components:
- ffmpeg based MPEG4/H.264 decoder
- color converter component YUV -> RGB
- video renderer based on devFB
New audio component:
- audio file reader based on ffmpeg audio format
- volume component
Fixed known bugs:
- FFMPEG audio decoder now works on FC6 and other distributions with the latest ffmpeg release (0.4.9-0.35.20070204)
Known pending bugs:
- some ogg streams can not be decoded properly
- the tunneling between file reader, mp3 dec based on ffmpeg - alsa sink ends in a deadlock sometimes.
- This behavior has been detected some times using FC6 and UBUNTU, not with the FC4
Full list of components:
Audio:
- ogg decoder based on libvorbis (stand alone components, and multiple roles component)
- mp3 decoder based on mad decoder
- mp3 decoder based on ffmpeg (multiple roles component)
- volume component
- alsa audio sink
- ffmpeg audio file reader (to be used with mp3 ffmpeg decoder)
Video:
- MPEG4 decoder based on ffmpeg (multiple roles component)
- H.264 decoder based on ffmpeg (multiple roles component)
- Color converter based on ffmpeg
- video renderer based on devFB
- Major additions to the 0.2
- New port classes
The components are:
- multiple formats audio decoder component that supports mp3 and ogg audio formats
- alsa sink component
- all the other components are NOT compatible with the new architecture.
- They have been removed and will be ported to the new architecture in a further delivery

Apache::No404Proxy::Google is an implementation of Apache::No404Proxy.

SYNOPSIS

# in httpd.conf
PerlTransHandler Apache::No404Proxy::Google
PerlSetVar GoogleLicenseKey **************

Apache::No404Proxy::Google is one of the implementations of Apache::No404Proxy. This module uses SOAP::Lite to fetch Google cache.

pypng 0.0.9 is an excellent and must-have product which offers you a Python module to decode (read) and encode (write) PNG files. All PNG formats are supported. Pure Python so that it can be installed as easily as possible and used on different Python implementations.

libstratanetsh project provides source-code to a library (formerly called libnetshclient) for use in the development of applications which require direct communication (using the netsh protocol) with a Foxmoxie Networks STRATA-family router, or any STRATA protocol-capable implementation.
This library may be used to develop client or server implementations, and has also been used for purposes ranging from file transfer to voice applications.
Enhancements:
- TLS implementation optimized, updated API, server-operation support, bugfixes

Heimdal is an implementation of Kerberos 5, largely written in Sweden (which was important when we started writing it, less so now). Heimdal project is freely available under a three clause BSD style license.
Other free implementations include the one from MIT, and Shishi.
Enhancements:
- Several bugs in iprop were fixed.
- Platforms without dlopen are now supported.
- RFC3526 modp group14 is now included by default.
- [kdc] database = { } entries are now handled without realm = stanzas.
- krb5_get_renewed_creds and kaserver preauth were fixed along with other bugs.

The c prototyping tools library consists of implementations for several widely used data structures and patterns as well as rudimentary tcp / httpd functionality. Object oriented development environments usually feature readymade implementations of such tools.

cprops provides standard generic data structures, socket and threading facilities in c.

The libcprops fills in a gap in between the standard c api dating back to the 1970s and functionality needed the times of ubiquitous http services everywhere.

Coding in c often allows better performance and closer control over application behavior, which can be crucial in many real life situations.

The purpose of the libcprops is to provide generic tools for application development in plain c covering basic data structure implementations, persistence, threading and tcp communication. It was almost called libc2ee but luckily this was narrowly avoided.
