This challenge is the first real life program I wrote with Haskell.<p><a href="https://github.com/Mgccl/mgccl-haskell/blob/master/random/unshredder.hs" rel="nofollow">https://github.com/Mgccl/mgccl-haskell/blob/master/random/un...</a>
(so it seems I don't like to specify the type of my functions...)<p>Explanation is here: <a href="http://chaoxuprime.com/2011/11/a-solution-to-Instagram-engineering-challenge-the-unshredder-in-haskell" rel="nofollow">http://chaoxuprime.com/2011/11/a-solution-to-Instagram-engin...</a>
I (kind of) solved it with CoffeeScript but thought it wasn't a good idea to publish… if you do it's not a challenge anymore, is it?<p><a href="https://github.com/ricardobeat/instagram-challenge" rel="nofollow">https://github.com/ricardobeat/instagram-challenge</a>
Very neat. Makes me kind of embarrassed that I never got around to actually solving this challenge. I've had the web page open on my laptop since it first showed up on HN.
Me too, and no response. I really wanted that T-Shirt...

So is this challenge over? I submitted an entry using Canvas as well but allowed users to drop image in from their desktop (only works in Chrome/Firefox though). Haven't heard from anyone at Instagram.
I solved it in ocaml, I only had this development environment this week end but it was fun. I didn't posted it on my blog but if someone wants it, just ask ;)
