On-line database

http://lazybase.com - The free service Lazybase lets you create/share a database on your browser with a few mouse clicks. To create a database, just provide your e-mail address and database name and push the `create' button. The service will send you two links: one for administering your database and the other for public viewing of it. You can create several tables (here items) in a database. An excellent feature of this service is the facility to generate a bookmarklet for entering the data directly from the browser. You can create a data entry bookmarklet that automatically fills up some fields using the information from the page (like selected text, page URL and page title) being viewed.

BarCamp

BarCamp (http://barcamp. org/) is an attempt to conduct a conference in an open-informal and participatory-environment. Here, no one is barred from attending the conference or making a presentation. Complete planning is done through Net based communication tools (blog, IM, e-mail, Wiki and the like) and word of mouth. As the BarCamp kind of conference is conducted in a totally unconventional fashion, it is also known as `Unconference.'
