Chicken-SDL and Chicken-Cairo are libraries for Chicken Scheme that have bindings for the Simple Direct-media Layer and Cairo vector graphics respectively. They are in active development by Tony Garnock-Jones and Michael Bridgen.

CVSZilla is a combination of Perl and Java to integrate CVS, Bugzilla and CVSWeb or ViewCVS. It extends CVS to give rudimentary support to 'change-sets', or 'transactions', after a fashion - they are not precisely what most people refer to as change-sets, but they're close enough for use here.

The core was originally written by Tony Garnock-Jones with Michael Ngarimu. It has recently been extensively rewritten by Matthew Sackman in order to introduce more features and is now largely in maintenance mode.

A series of Lingo scripts to allow Shockwave and Director applications to communicate easily with online data stores developed by Andy Wilson.

The scripts can be used to communicate with any webserver, and any RDBMS database, but example ASP scripts communicating with an Access database are included showing how the DirectorComms scripts can produce a SQL query analyser in your own Director movie.

gAlan is an audio-processing tool for X windows and Win32. It allows you to build synthesisers, effects chains, mixers, sequencers, drum-machines etc. etc. in a modular fashion by linking together icons representing primitive audio-processing components. Developed by Tony Garnock-Jones.

Jabber.el is a functional emacs-lisp extension that turns your emacs into a jabber client. Originally built by Tom Berger.

The JS/CORBA Adapter, developed by Matthias Radestock, provides a mechanism for arbitrary Javascript objects to interact with each other transparently in a distributed Javascript system using CORBA.

Luna is a Scheme compiler and run time environment for .NET - it is written in C# and Scheme, and provides a useful superset of the R5RS standard. The system is still under development, and is designed for tight integration between Scheme and the .NET environment. Developed by Tom Berger.

MetaPlatform is a minimalistic lazy functional language with metaprogramming features, intended to become a platform for rapid programming languages development. Currently it works on top of JVM and supports a complete Java reflection, so it can be used as an embedded JVM language as well as for the Language Oriented Programming research. Developed by Vitaly Lugovsky.

NTDCRealm is a Tomcat realm that authenticates users against an NT domain controller. This is especially useful for intranet projects where the web authentication models duplicates the LAN authentication of an NT domain (using an older NT server). Developed at LShift by Tom Berger.

Pyle is a WikiClone - an implementation of a program sharing general ideas with the original WikiWiki developed by Ward Cunningham. Developed by Tony Garnock-Jones.

RabbitMQ is an implementation of AMQP, the emerging standard for high performance enterprise messaging. LShift built our implementation in collaboration with CohesiveFT. Code was developed by a team including Tony Garnock-Jones, Matthew Sackman, David Ireland and Matthias Radestock.

Timetracker is a Java application for recording time usage to a shared or personal database. Timetracker was developed at LShift by Michael Bridgen, Tony Garnock-Jones, and Paul Crowley.

You can download either the binaries or the source of Timetracker.

Timezilla is a Java web application for linking data in Bugzilla with data in Timetracker. Developed by Lee Coomber.

TrustFlow is a new "trust metric" algorithm, which uses human-generated information about trustworthiness in a human-sized community of a few hundred people to generate guesses about trustworthiness in an Internet-sized community of millions of people; this is useful in applications from search hit ranking to spam prevention. TrustFlow is unique among "attack resistant" trust metrics in that it can load information about who trusts who incrementally as needed; this makes it well suited for distributed use.

TrustFlow is under active development by Paul Crowley; the current module examines friendship relationships among the million-strong LiveJournal community, and has gained around eighty thousand visitors.

A JSP Taglib template library written by Sam Jones designed to effect a clean separation of business logic from page design. Influenced by the HTML::Template Perl module, it has a deliberately small set of tags to perform common tasks such as variable substitution, looping and conditionals.

xxexpr was written by Tony Garnock-Jones. It takes SXML (Scheme S-expression representation of XML data) and converts it to XML 1.0 markup, with optional pretty-printing, etc.
