Here are two very useful tools from Yahoo that you might add to your tool box... Yahoo Desktop Search and MyWeb. In my current job I have to work on a large legacy application. The application has been in development for more than eight years. It has a large amount of source-code and documentation. Finding information in this mass of files was very difficult until I used Yahoo Desktop Search. Search has a great interface for performing the searches and previewing the results. It handles source code, word, pdf and many other documents. So when I look up a function in source, I can easily spot everywhere it is used in code and in the documentation! Very very nice. I tried using Google's desktop search tool, but found the Yahoo Desktop Search to richer and easier to use.
I read a lot of technical articles, whitepapers and blogs. On any given day I probably read 2 to 10 articles about technologies I'm using. That is a lot of information to keep track of. My solution is Yahoo's My Web. Since late May (see previous post) I've been dropping every article I read into MyWeb at Yahoo. MyWeb captures a copy of the webpages so I can search them later. [Hint, use Yahoo Toolbar to make it easy to add to MyWeb.] So the next time I need to find that article on JTidy, Derby, or AspectJ I can use MyWeb to search only the articles I've read.
Maybe one day Yahoo will get the Desktop Search to also include MyWeb. That would be Nerdvana!
