grep-dctrl. this tool is great for searching information on debian packages. personally, i find those browsing tools like aptitude are horrible time sink. maybe just for a debian junk like me. :)

on a side note, the bleeding edge of unstable is in trouble now: (i) acroread cannot work; (ii) openoffice cannot work; (iii) scim cannot input japanese. be warned. :)

bnfc and lhs2tex. two lovely tools in and for haskell.

i failed to find interesting things in programming languages. i learned programming about five years ago. after that i was just wandering in the land of programming languages and failed to find anything of significance.

about two years ago, i began to learn game theory and eventually economics. i think i've found something this time. but it is totally unrelated.

my current project in economics will end soon no matter what. i hope to do some programming work again.

since the previous week, a few more sites i frequent were inaccessible. it may be tech problems. but you can't help yourself thinking other ways. it's like: the tide began to change. :)

mathwriting.ps. Mathematical Writing by Don Knuth et al. the more people read it, the better. :)

Steven Cheung 张五常在《卖橘者说》says vote by money is the best. My intuition is he is wrong. But I didn't know how to argue. A few days ago, I finally have a theory. :)

I read Karl Popper is against social science. certainly i disagree. but the argument is subtle. i remember when i first read Karl Popper quite a few years ago, i agree with him on this. i study game theory these days. in BusinessWeek, there was an editorial on this year's Nobel economics. the article blasts game theory ``not testable''. i agree. but i can make some change. :)

books by 吴思 are the best economics books i was reading so far. it's deep but it lacks mathematization. contemporary game theorists' work are good mathematics. but often bad economics. this is echoed by S Cheung and 杨小凯. it's interesting time for an economist.

i remember Knuth once said the 60s and 70s were golden times for computer scientists. it's like that for economists now.

yo! i'm back. :)

happy happy joy joy. :)

read or die. :) なんしさん is cool! :)

today's good laugh from wikipedia general equlibrium:

... Some critics of general equilibrium modeling contend that much research in these models constitutes exercises in pure matheamtics with no connection to actual economies. "There are endeavors that now pass for the most desirable kind of economic contributions although they are just plain mathematical exercises, not only without any economic substance but also without any mathematical value" (Nicholas Georgescu-Roegen 1979). Georescu-Roegen cites as an example a paper that assumed more traders than there are points on a real line.

in these days, news from the arena of programming languages only reminds me how people can easily get excited over trivial things.

empirical and theoretical. many and many big volumes of trivialities are produced. and not necessarily easy to be learnt.

life is very short. time spent to learn a new, so called, fundamental innovation in programming languages, could be better spent elsewhere.

learn chemistry. learn economics. there're many whole world unknown to me. watch another japanes anime or tv series. they teach me more than old Alan Kay or old Guy Steele.

lisp or unit testing, i'd better spent more time with my life partners.

don't take me wrong. i like collecting programming languages. to this day, i've collected some of c, of course, and scheme and forth and c++ and java and python. and a little bit of perl and ruby and ocaml and clean and erlang. and even less so with a few more bizarre ones.

i've also collected some programming practices, such as literate programming, and such.

it's a difficult thing to say. it's like you asking me if i support the death penalty. i just can't give a quick answer.

but i do dislike people give easy answers in the face of real difficult questions.

there ARE real questions in the field of programming languages research.

for a quick and conservative adoption of scons, GenerateConfigH provides excellent example.

in fact, that example could be even simplified a little bit more.

it should be noted that it's still easy to provide the user the usual interface to a source package:

$ ./configure
$ make
$ make install

just dump the m4 and autotools, in favour of python and scons. (i think it should be perfectly ok if one has nothing against make, especially when one's project is small.)

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.

If you're a C programmer with some spare time, take a look at the mod_virgule project page and help us with one of the tasks on the ToDo list!
