Re: [Haskell-cafe] Re: Reflections on the ICFP 2009 programming contest

The main thing my team implemented in Haskell was a simulator simulator that took the first two rounds worth of port information and used that to back into the velocity for each of the satellites. This meant we really only had to appeal to the actual VM implementation for canonical scoring and to validate results, which was kind of nice. We implemented the VM itself independently in python and C to cross-check ourselves and I later put together a small VM->C compiler once we knew we had the implementation right. -Edward Kmett 2009/6/30 Eugene Kirpichov

We implemented the VM by writing a smallish compiler to C for it in Haskell. It ran *damn* fast, but we couldn't get rid of some bug that did not let us run the 4rth task at all, although the others worked fine :(

I implemented the VM in C, it was pretty obviously geared towards such an implementation and it took all of an hour. Then I interfaced with it via the FFI. Why use just one language when you can use two? :)

You could also have used Data.Binary. That's what I did.

I wasn't able to make any time on sunday though so didn't end up submitting a final entry which is too bad. this was an interesting one.
