Are you going to ICFP 2011 in Japan? Do you work with Haskell? You should consider offering a talk for the Haskell Implementors Workshop! You have until this coming Friday (22nd July 2011) to offer a talk, by emailing an abstract (less than 200 words) to benl -AT- cse.unsw.edu.au - for full details see the Call for Talks. Talks are 20 minutes long, plus 10 minutes for questions.
What topics are suitable?
If you have been doing or thinking stuff that would interest a bunch of Haskell implementors in a pub, you probably have something suitable for a talk. The aim of the workshop is to provide an "opportunity to bat around ideas, share experiences, and ask for feedback from fellow experts". Unlike ICFP or the Haskell Symposium, there are no published proceedings. If you have some work that isn't quite ready for a more formal setting, this workshop is a useful venue to seek feedback. If you have an idea which seems a bit crazy, it's probably also very interesting!
What if I have less to say?
In addition to the 30 minute talks, the Haskell Implementors Workshop will also have 2-10 minute lightening talks, organised on the day. Attend the workshop, and sign up on the day to give a brief talk.
