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

Vis/Space is a client-server system for visually exploring data structures in 3D virtual space. It allows the placement of various data sources in a three-dimensional environment. Custom search terms can be entered into a query field, or can be navigated to and from an existing object. All objects like images and "text screens" can be moved around. 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.
