Are there any librarys for mood matching a song. i.e. some algorithm to finger print every song and shuffle the list by my mood(the current playing file(s))?
Cheers,
Mark

I found this hard to believe, but "There's an app for that". MoodAgent apparently does what you're talking about. You might be able to download it and do some reverse engineering based on the capabilities already in the software.
Thanks for the question - it made me find what could be an interesting piece of software.

Heres some interesting things I have found

I'm having a really hard time visualizing how the Bellman-Ford algorithm works purely through reading code. Does anyone know of an visual example (video, slideshow) that works through an actual graph with that algorithm? Thanks!
I think that this page might be what you are looking for. It does indeed run through the algorithm on a graph, and you may use the UI below to pause the visualization, or run through individual frames one at a time so that you can visualize it at your own pace.

a few weeks ago I saw a website with a powerful generator to create beautiful pictures of own source code files. The generator created images with variable effects like perspective transformations and depth of field, etc.
Typically I don't ask such questions in here but I googled more than 2hrs and I cannot find this generator anymore. I'm really going crazy - I know this site exists ...
Here's a sample picture of code made with this generator:
Thank you very much!

I'm looking for an algorithm that can tell me where are the eye(s) looking at on a photo/webcam realtime feed.
I've already searched a lot but I don't want to start with a lot of complexity right now.
It's just for fun. My idea it's to have some method that receives an image and returns a coordinate with the place that the user is looking (on the computer screen).
