In a similar fashion to embarrassing post-SBCL-release bug fixes, a bug fix to my previous diary entry. Having established the contrast between the corporate “interesting problems which we happen to solve with Lisp” presentations and those focussed on the lisp ecosystem itself, I intended to say that the talk given by Tiago Maduro Dias and Luís Oliveira from SISCOG about their company presented a difficult and interesting problem, but also presented their individual and corporate experiences of working with Lisp, which I think plays to the real strength of this kind of event, by offering experiences for other practitioners to learn from. I particularly loved the deadpan reporting of the informal surveys of the SISCOG engineers’ attitudes to Lisp and Emacs, and the frank assessments that some of the pieces are not good enough.

Instead of saying all that about the SISCOG talk, I left it out completely. Go me. Since making amends for that gives me another chance to talk about last week’s events, I'll also mention that I “live-tweeted” as an experiment; I'm not sure whether it's more annoying than useful, but the theory is that it acts as marketing and public relations as well as a handy notepad for when reconstructing events to make blog posts. I also managed to squeeze a tiny bit of development in: a minor improvement to SBCL’s console debugger, a fix to a long-standing bug in SBCL’s type derivation of expt, and adhering to codepoint-by-codepoint case consistency requirements imposed by the ANSI CL standard for characters composed with ypogegrammeni (that’s iota subscript to Attic scholars, or “is that a speck of dust or what?” to you and me).
