Flickr Follow Comment is a Greasemonkey script that improves Flickr's "Comments You've Made" page. It allows you to see 10 pages of comments and filter the comments displayed to show only photos from your contacts/friends/family with new comments, photos with new comments and less than 10 since yours (so you can still see your original comment), photos with new comments that you have not marked as ignored, and photos with new comments since your last visit to the "Comments You’ve Made" page.
Diagnotep is an affliction search engine to help diagnose medical problems. It searches among the symptoms of a medical database, so the results will only be medical afflictions. The links from the results page point to affliction pages which are either public domain government pages or pages licensed under the GNU Free Documentation License.
Ojax provides an OAI-PMH harvester to harvest metadata from multiple repositories and builds a single searchable Lucene index of this data. OJAX provides a dynamic user experience enabled by Ajax and full OpenSearch integration with the IE 7 and FireFox 2 search fields. It supports OpenSearch Discovery, OpenSearch Atom results, and OpenSearch Search Suggestions. Loosely coupled Web Services and OpenSearch Atom standard allow integration with a range of VLEs, CMSs, institutional repositories, and portals.
A.E.P. (Ajax Extensible Page) is an AJAX framework that is very easy to use, with an interface of six functions. These functions allow you to build Web pages that are extended at the user's request from data hidden in the page or taken from external files. Text is extended at a word or as a whole. A short tutorial is provided in HTML and PDF forms. The archive includes some small demos you can use to start with the tool.
Address Book Continued is a multi-user address book Web application. It also makes use of AJAX, which means that page reloads only happen on login/logout; the rest of the operations is handled asynchronously in the background. It's well usable, even over slow connections. You can even install ABC on your desktop PC and configure it so that it doesn't require login for connections coming from the local computer.
