I really need access to play, pause, stop, seek, fullscreen, etc. I'd also like to have access to any events the player happens to broadcast. Hel...
Does anyone know a good tool that can be run on a page (for asp.net, for example) to help to minimize the footprint size of the page? The page will have typical items: HTML, Javascript, etc. I've heard of Javascript crunchers in the past, that will make the size of the code as compact as possible (and obfuscate it, I suppose). The goa...

I sign up Spring courses tomorrow morning (transferring in to the Computer Science program). Since I'm a transfer student, I get the last pick of leftover classes not already taken. Emphasis on 'last pick' and 'leftover'. It's highly probable that whatever classes I intend on picking tomorrow, I might not even get because other students ...
