Are you a Lisper, in the big-tent sense of the term? You within a day's transport of St. Augustin in Germany? Well shucks, have I got a thing for you: Quasiconf, a lisp sub-conference of FrOSCon, held next weekend (25-26 August 2012).
The full program isn't quite out yet, but they invited yours truly to talk there, and talk I will. In fact I'll talk thrice: they gave me 90 minutes, so I'll do three little presentations.
In the first, I'll finally give that talk I've been threatening to do for years, about why delimited continuations are the bee's knees, how they can be implemented, and what kind of lovely code they enable. The example will be a small memcached server and client.
Finally, now that Guile 2.0 has been out for a year and a half or so, it's a good time to look back at what worked well and what didn't. If you are even remotely interested about what it takes to maintain and enhance a mature language implementation, this will be an interesting talk for you. I'll also take the opportunity to summarize the progress on the development branch, which will probably be Guile 2.2.
So that's the thing. It's somewhat of a late announcement, but hey, if you can go, it's pretty much free and should be an interesting get-together. See you there!
