LtU node of the week
To try and get more regular about posting diary entries, I've dedided to adopt the semi-strict discipline of choosing to link to a Lambda the Ultimate node each week (either a new story or forum article, or something classic from the archives). I'll start this week with the very fresh.
Week 1: Node #587: The fate of reduce() in Python 3000, which has become a sort of forum for complaining about/defending Python's piss poor support of core FP style. Regular readers of this diary will probably have become aware that my attitude to the language moves around the spectrum from "distaste" through "irritation" and "outrage" to "cold hatred".
Thoughts on Recentlog
I'm reading the whole of recentlog, at thresh=2 much more often these days (my default used to be to just skim it at thresh=6). Very pleased to see ncm and raph posting again, welcome back! (And sorry, ncm, about the unwelcoming nature of my last post...).
A point: the reason I am reading recentlog more fully these days, is not having more time on my hands, but because it is faster to do, because fewer people are posting, and more rewarding, because the idiots have all moved to flashier ways of pulluting the blogosphere. Time, perhaps, for an advogato renaissance.
Pace raph, I don't think there is anything wrong with the trust metric, besides it's being meaningless-in-aggregate. Together with the underutilised diary rating mechanism, it really succeeds in keeping me stop reading crap on recentlog, with little personal effort, which is a very nontrivial accomplishment for an open community site. I'd say: experiment successful, but not quite in the way planned.
Today's responses on
zhaoway on today's good laugh from wikipedia general equlibrium: I think economists don't tend to think hard enough about what they are taking for granted with the kinds of mathematical models they use (I'm a Neo-Ricardian, after all), but I can see why I might want to use assume I had at least as many traders [as] there are points on a real line when doing equilibrium modelling:
A trader is someone who performs actions in response to markets. Markets provide a sequence of pieces of information in real time. Hence an equilibium model ought not to behave differently when you assume the existence of all possible traders, who will number at least |(Time => Information) => Action|, which if |Time| >= Nat, and both |Information| and |Action| are >= 2, will number more than there are real numbers, or indeed continuous functions on the real numbers (both of the => funcation space formers should include at least some discontinuous functions under most reasonable topologies).So, in short, I don't find the assumption ridiculous.

Google search for Siskind's
It takes a lot of qualifiers to get J. M. Siskind's ruthlessly optimising scheme compiler appear on the first Google hit for stalin, but "stalin -hitler -joseph -death -inurl:logs - USSR -Avidenko" does the trick...
Edit (2008-10-20): Fixed link to Stalin, above — I guess Advogato's html reformatting engine claimed another hyperlink...
