Open-Source Web Conferencing Solution

Dimdim is a free and open source web conferencing solution that hopes to compete with WebEX and ASAP. Although still in alpha, this product shows a lot of promise. The software is easy to setup and manage and serves up meeting content from the system that you install it on. The conference manager application runs in a web browser (MS IE only at this time but Firefox exensions are in the works) and the conference manager can upload only PowerPoint presentation at this time. The attendee only needs to have a web browser with Flash. We tried it out in our office recently and it worked very well.

Free Open Source Basecamp Clone

activeCollab is a free open source project management and collaboration tool. Like a Basecamp open source app, this web-based application is very similar to 37 Signal‘s Basecamp project management tool, but instead of a hosted service, activeCollab is an application you download and install on your web server. The tool requires PHP and MySQL, so should be easy to install on most hosting packages. Aside from the money you’ll save, this appears to be very easy to install and it has most of the functionality of other project management tools.

If it is not too much of it technical or practical inconvenience for you to put it on your own server this will be a preferred solution for many people.
