Yay, I retrieved my passwort. :)
During my absence, I've written a bunch of useful Haskell stuff (to be found at my website). But most importantly I've co-founded the KHJK, basically a society for mad scientists and futurist engineers (*g*). I hope to shell out some great stuff for/with this organization.
My current task is to develop a metadata-centric filesystem that should be able to serve both as a long-term archival facility and a backend system for an automated website, i.e. an istant publishing tool. Incidentally, it should also be suitable for email message posting in the style of IM2000. Oh, and for blogging. ;)
I think I would like a predicate logic metadata-base, and a query language like Prolog. I think I should define some common predicates ("title", "created", "modified", etc.), rules (reflexivity, transitivity, etc.) and some kind of textual representation for these relations first. Then I will think about the best way to query this system from Haskell. Via an interpreter, this will also yield an immediate command-line interface to the database. I've been wishing for a Haskell command shell environment for some time. Maybe this can be combined. All the basic functions are in the standard library, one just has to build a specific Prelude that imports them all, possibly with shorter or more mnemonic names.
But for now, I need to prepare my lecture at this year's Chaos Communication Congress, which is going to be about Lojban, another topic which I am pretty excited about. For those who don't know, it's a constructed (spoken!) language based on predicate logic. Everything is very clear an clean. I like! :)
