I had some fun implementing binmaps a while ago - http://scattered-thoughts.net/blog/2012/01/03/binmaps-compre... I originally encountered them in http://libswift.org/ which was the predecessor to http://datatracker.ietf.org/doc/draft-ietf-ppsp-peer-protoco... . Both are very elegant simplifications of bittorrent and the IETF draft is pretty readable.

Jamii I've seen your ocaml implementations, your code has been very instructive - thanks!

How do you manage in erlang without mutable arrays? It must be expensive to build it out of tuples.

the PPSP one, if you're going to be around at IETF let's discuss there. https://datatracker.ietf.org/meeting/89/agenda/ppsp/

Can anyone who is interested go along and sit in on those sessions? I live in London and that sounds interesting.

physical attendance at the conference costs; it's minimal for a day session for a student, but its possible to listen in remotely.

atm I'm not doing live streaming so I can store & reload these from disk. I'm likely to end up using hipe_bifs:bitarray* or https://github.com/ferd/bitarray where those are not available, if needed. See http://erlang.org/pipermail/erlang-questions/2009-May/043485... for an example.
