I havn’t looked much under the hood of Eclipse, but it seems to me to be one of the most extensive and flexible open source products out there. I am really impressed by how it supports plugins, as well as their internal update manager. One example pf customization can be found here with creating a new splash screen as a plugin.
So it’s finally been published. I was wondering how they were planning on including all those names, but they’ve done an excellent job. PDF here.
Google suggests has gotten a great deal of attention lately. It really is a good product, but it is also a technically advanced product because it dynamically updates the results as you type (remember, this is a webpage). A dissection of the code can be found here.
