JWIM : A JavaScript window manager that allows programmers to load independent modules inside Web applications

JWIM is a JavaScript window manager that allows programmers to load independent modules inside Web applications. It is totally AJAX based and does not make use of inner frames. Any module acts as an independent page, so it can display HTML, run JavaScript code, get access to HTML elements (in the same manner as document.getElementById does), and can be loaded multiple times. To achieve those features, modules have their own scope to store data and to run code. Modules can be loaded inside dynamically generated divs that behave like windows, or attached to HTML elements to build static layouts. Jwim is primarily intended to split large AJAX applications into small files that are loaded dynamically and run in an isolated environment.

Hudson monitors executions of repeated jobs, such as building a software project or jobs run by cron

Hudson monitors executions of repeated jobs, such as building a software project or jobs run by cron. Among those things, current Hudson focuses on the following two jobs:

1. Building/testing software projects continuously, just like CruiseControl or DamageControl. In a nutshell, Hudson provides an easy-to-use so-called continuous integration system, making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build. The automated, continuous build increases the productivity.
2. Monitoring executions of externally-run jobs, such as cron jobs and procmail jobs, even those that are run on a remote machine. For example, with cron, all you receive is regular e-mails that capture the output, and it is up to you to look at them diligently and notice when it broke. Hudson keeps those outputs and makes it easy for you to notice when something is wrong.

Vis/Space : A client-server system for visually exploring data structures in 3D virtual space

A single click on an image shows the full-resolution version in the foreground. Whole collections of images can be moved. A click to the cube also toggles among several different possible layouts. Data sources include search engines, microblogging, Wikipedia, image/video search, and 4chan.

Sustainable IDE (SIDE) : A set of graphical tools for developers who want to build sustainable software

Sustainable IDE (SIDE) is a set of graphical tools for developers who want to build sustainable software. Sustainable software is software you can extend easily, from a functional or technological point of view. On one hand, this means that when a user has a new requirement, it's easy for any developer to add it, even if the original author is not there anymore. On another hand, if you want to change the underlying technologies, you don't need to rewrite your existing application from scratch. Sustainable Software gives you the freedom to change technology, requirements, or achitecture. This can be achieved thanks to the use of models in a model driven software development (MDSD) paradigm.

Triage provides interfaces for handling tickets with notes and solutions, full-text search indexing, and allowing for plug-ins which can generate tickets from external sources (for example Asterisk, OpenNMS, Nagios, and e-mail). The initial development is being done on Linux, using the Eclipse development environment. The idea is that as a technician enters a new ticket, the application will present them with previous tickets/solutions which may be related and be able to present a quick answer. This way, knowledge is not lost and can be easily leveraged even with new personnel in the IT work force.

Jenner : A Web page templating system with a twist: it runs completely within a Web browser

Jenner is a Web page templating system with a twist: it runs completely within a Web browser. Templates are just normal Web pages with special syntax inside text nodes, attributes, or comments. Unlike other in-browser templating systems, Jenner does not require overloading of "class" attributes or invalid HTML; all Jenner templates are valid Web pages and the template expressions flow in a very natural way. Having the template engine in the Web browser instead of on the server takes a lot of load off of the server, and makes for a clean separation of presentation and content. Jenner is very powerful: it has the full power of the Esel expression language at its disposal. Templates can be rendered from JSON data, and can be re-rendered without a browser-to-server round trip.
