Vanity blog

As a consequence of the above mentioned feature of mine I am depressingly bad at keeping vanity blogs updated. This is clearly evident from my diary here.


Bugs in Writing by Lyn Dupr\'e and G\:odel, Escher, Bach by Douglas R. Hofstadter. The former is part of my mission to become a better writer; the latter is good philosophical reading.


I got tired of Twisted some time ago. So, in a fit of Hybris, I wrote a network-programming library using stackless tasklets, and built a web server on top of it. Also, I implemented most of Zope Page Templates. Put those two together, and you get a web server that you can easily hack, along with nice separation of logic and presentation. And you get it without the icky frameworks that the Twisted (and Zope, I suppose) crowd like so much. I like it. A lot.

olandgren: The problem with composing addlist and pairwiseMult is that pairwiseMult needs to have signature int list -> int list not int list -> int list -> int list. By wrapping it all up in a function you can fix things just nicely: val dothigh = fn l => addlist o (pairwiseMult l);.

olandgren: About continuations, there is a undergrad course in Programming Language (Theory) at DIKU which have some on-line lecture notes on continuations, among other things.

[ Correction: I s/CORBA/ORBit/'ed in various places. ]

Hacking: [Beware: ugly-ish picturesque langauge] Blech -- I thought I was going to have some Good Wholesome Fun(tm) fiddling with CORBA in Python. Then I discovered that PyORBit is (1) completely undocumented and (2) sucks goats nuts. orbit-python OTOH needs me to patch automake before I can build it, could they at the least not have include pre-autogenned files?

I better see go see if a patched automake will make orbit-python (and hopefully me) Happy.

Hacking: I've finally gotten around to doing some hacking; for the two past nights I've been doing the grunt-work of a freeciv-protcol library in Python. I'm not sure if I want to take it much further, though, or if grokking the protocol (my original goal) is enough. . .

Having a freeciv client (oh no, not another freeciv client!) in Python might be the entire exercise worth, though. Should make scripting a fairly easing thing to integrate. Mmm. . .

Work: Greatness abounds at work. Almost all of today was spent writing a custom, RAID-capable, company-specific Debian installer; just having to enter hostname, etc. and have a Debian base-system on RAID when you come back from the coffee-machine is going to rule. Oh, and the best thing ofcourse is that's it's fun doing :-).

Scheme: What better way to spend the time of your lunch-break at work than solving mbp's Scheme-challenge? I can't think of any, so here's my stab:

-- (define (f s)
  (lambda (g)
    (if (equal? s "")
	(let ((t (g (lambda (h) ""))))
	  (if (equal? t "")
	      (g (f ""))))
	 (string-head s 1)
	 (g (f (string-tail s 1)))))))
-- ((f "Js nte ceeWnae")(f "utAohrShm anbe"))
"Just Another Scheme Wannabee"

Wonder if not there's a nicer way of doing that then-branch?

And, now back to my regularly scheduled work.

work: I have not been to work in something like two weeks time, exams taking their toll. So, not much to say but that I'll be going back in-to the trenches tomorrow, yay!

comp.sci.: My one exam is finally over; hopefully I'll never again have to hand-craft SLR-parse tables, or convert IEEE floats from binary to decimal.

comp.lang.python: Sadly a lonely post to comp.lang.python is the only hackish thing I've done in a while; it seems I learned something from my first-year comp.sci. programming-and-data-structures course, though, since I cooked up a binary search of a list of numbers in no time (as is only fitting :-).

real programming(tm): I have been thinking about getting back into freeciv-hacking, as I recall it was actually not so bad. I probably spent more time hacking the sources than playing the game :-). <rant> This was probably brough on by my getting pissed with Activision after buying CtpII. CtpII is probably the suckiest Civilization-clone out there. For one thing the AI is so bad it probably could not beat my old, computer-illiterate grand-mother. And don't get me started on the UI, makes me want to cry :-/ </rant>

att. conservation notice: first diary, c.s. student, unix sys.adm.

work: nothing much interesting to say here, I work as (part-time) system administrator for a small web-enabled company, where I am the local *nix guru, Perl hacker and geek in general. Good job, nice people and good perks, and I just got green light to move our servers to Debian (they are being reorganized).

edu: computer science major, with a minor in math., trying to prepare for exam (T-7days and counting). C.S. is generally a full of cool things for me to learn, but there are some really boring things too, for example creating SLR-parse tables by hand :-(.

programming: hmm. . . I did some Windows programming yesterday, needed to somehow get a list of existing drives. It seems one cannot do this, so you have to do something like,

  for(int i=1; i<26; ++i)
      printf("%c exists, whee!\n", 'A' + i - 1);
hackish, to say the least, imho.

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.
