I'm currently working on a little project that has a new spin on Pastebin. I'm playing with a Bayesian classifier (or attempting and learning a lot) to auto-detect the language and appropriately set the syntax highlighting automatically without a dropdown and a reload. The paste will also be saved automatically so there isn't a page load for anything.

I'm still hacking away and haven't got very far whilst I'm getting my head around the classifier. One other problem I've noticed is keeping track of ownership. One solution I have in mind is that there is no ownership: when it's modified it generates a new link to share with. It might be good for very simple code collaboration - I've tried doing this with Pastebin over Facebook chat and this should make the process a whole lot smoother.

I also need to think about how training will work. I envisioned it so that the user can train it i.e if it guesses wrong, the user would correct it by selecting the proper language and the program will learn for the future. I'd be putting a lot of faith in potential future users but I'm not expecting it to be big or anything, maybe just something me and my friends can share and work on code friction-free (some don't have GitHub/BitBucket/etc accounts, one doesn't like CAPTCHAs at all).

I'm currently going off 100% self-education here too so I'm having to get to grips with some other maths stuff like some symbols (such as | means conditional probability and _not_ to be confused logical OR), so if the project falls flat on its face at least I learned something from it :)
