Wayback Machine is an open source java implementation of the The Internet Archive Wayback Machine.
The current production version of the Wayback Machine is implemented in perl, and lacks in maintainability and extensibility. Also, the code is not open source. Primary motivation for the new version is to address these three issues, enabling public distribution of the application, and easy experimentation with new features and access technologies.
The current Java version of the Wayback Machine supports two access, or replay modes of operation: "Archival Url" mode and "Proxy" mode.
Archival URL mode provides a user experience very close to the current production Wayback Machine. All query and replay access requests can be expressed as URLs.
In Archival Url replay mode, HTML documents are delivered with additional Javascript embedded in the page. This Javascript alters the document within the browser, attempting to make links and embedded content refer back to the Wayback Machine by rewriting them as Archival URLs.
Proxy URL mode allows replaying of archived documents within a client browser by configuring the browser to proxy all HTTP requests through the Wayback Machine. This has the strong advantage that no Javascript page markup is required to coerce the client browser to request additional URLs and embedded content from the Wayback Machine -- content just works as-is. One major disadvantage of this mode is that there is no way to forward temporal information with each replay request. Because of this limitation, only the most recently archived version of any resource is accessible thru the Wayback Machine in proxy Url mode.
Another limitation of the Proxy URL mode is that it requires special configuration of the client web browser to access the Wayback Service. This browser configuration is not complex, but it means that content cannot be accessed as a global URL.
See the User Manual to learn more about access modes.
The current Java version is intended to operate as a standalone webapp, maintaining an index on the machine hosting the webapp. This index contains records of the resources within a set of ARC files, which are also assumed to be stored on the same machine hosting the webapp.
This software includes the capability to scan for ARC files in a specified location, and to automatically index and serve content in newly discovered ARC files as they appear. Directing the Wayback Machine to look for ARC files in the directory where an instance of the Heritrix web crawler is writing ARC output should provide the capability to browse content archived by Heritrix as it is crawled.
Future versions of this software may integrate more tightly with the Heritrix web crawler application.
Enhancements:
- A sorted CDX flat file ResourceIndex implementation was added, allowing for much larger data sets.
- Support for ArchivalUrl Date-Range requests was added.
- Character set detection was improved so pages are not mangled when server side modification occurs.
- Several new command-line tools were added for generating and updating each ResourceIndex type.
- Indexing and merging processing were separated into different threads.
- Bugfixes were made to allow integration with NutchWax full-text searching.

Conc is a console concentrator for Linux and Gnome. Conc project features remote maintenance of systems over IP, and concurrent connections to consoles.
Serial lines on multiple machines may be pooled into one system allowing a virtually unlimited number of consoles to be managed - ideal for large server farms, clusters or off-site server rooms.
Please feel free to try it out and send me any comments, feature requests, and bug reports.
The systems consists of three components. The first is concserv, the central daemon, that keeps logs from all the consoles and coordinates the rest of the system. When it starts, concserv spawns a number of termserv processes that control the serial lines to which the console lines are connected. The link between a termserv and concserv is encrypted and termservs may run on separate machines to concserv, communicated over TCP/IP.
The final component, conc, is the user interface. It connects to concserv over an encrypted TCP/IP link, and allows the system administrator to view the logs of a particular machine, connect to its console, add and remove consoles etc. There is also a small, text-based interface called console that allows connection to a single console.
Any number of user interface programs may run concurrently and multiple connections to the same are possible, allowing groups to work on one system. Having all the components communicate by TCP/IP allows administration of machines from off site or unifying management of co-located and local equipment.
Enhancements:
- This release improves the reliability of the connection between manager and servers, and removes the worst of the memory leaks from the client.

The Language Machine is a free software toolkit for language and grammar. It includes a shared library, a main program, and several metalanguage compilers with one frontend. The system is easy to use on its own or as a component.
The Language Machine directly implements unrestricted rule-based grammars with actions and external interfaces. A unique diagram shows rulesets in action.
Main features:
- rules describe how to recognise and transform grammatical input
- the left-side of a rule describes a pattern
- the right-side of a rule describes how the pattern is treated
- the left- and right- sides are unrestricted pattern generators
- the system is a kind of symbolic engine for grammar
- the metalanguage is very simple and very concise
- multiple grammars, rule priorities, left-recursion, right-recursion ...
- variables and associative arrays, a subset of javascript
- transformed representations can include actions and side-effects
- transformed representations can themselves be analysed as input
- can be used as a free-standing engine or as a shared library
- can be packaged together with precompiled rules
- very simple interface to external procedures in C and D languages
- built-in diagnostics with lm-diagram generator
- several self-hosted metalanguage compilers with a single front end
- compiled rules can be wrapped as shell scripts, or as C or D programs
- rules can be compiled to C or D code
- metalanguage source can be treated as wiki text in the Mediawiki format
Enhancements:
- modifications for compatibility with gdc-0.22 and dmd-1.010
- element.d - wrong indices to non-keyword array literal cells
- add src/dmd/Makefile for building with dmd compiler

State Machine Compiler takes a state machine stored in an .sm file and generates the state pattern classes in nine programming languages.
Its features include default transitions, transition arguments, transition guards, push/pop transitions, and Entry/Exit actions. State Machine Compiler requires Java SE 1.4.1 or better.
Enhancements:
- This release cleans up C# and VB.net debug output using System.Diagnostics.Trace.
- It fixes a number of minor bugs.

Alan project is a Turing machine implementation.

Alan is an implementation of a Turing machine for educational purposes.

It was created as a programing project at the University of Aplied Sciences Rosenheim.

Features include an easy-to-use GUI and a reusable Turing Machine component. Additionally, Alan contains many example programs for the Turing machine.
