Despite a series of legal wrangles involving software rights, work is mostly ok. Saw a real IP lawyer for the first time last week... scary.

ahhhhhhhhhhhhh. oh yeah, don't use the generic exception handler in g++.....

They say public journals are often used as a cry for help:


SIGSEVs in malloc????

lots of memory, try efence.... efence: no complains. (segfault)

string is a const char *  to a str literal...
trying to strdup a string....
(gdp) print string
$1 = "yey"
(gdp) print strlen(string)
this is like beating your head against glibC untill it bleeds bits....

i wonder what happens on solaris...

how on earth are you supposed to debug that????? same happens with strdup...

got a 1st in my degree, which is good i think. going to spend some time in southampton/bath, will help getting gote nice (promise).

going to write up my project for publication in IEEE s/w engineering.

Hmm bulk of core translation cludge is finished, (mostly buggy but i'll sort that tommorow)

Working on stuff to let you implicitly translate java runtime classes into promela using an XML..

it is really difficult to embed java/c language in xml without lots of entity translation.. ug.. currently i am on: <JAVABODY>[CDATA[ java.foo.bar ]]</JAVABODY> Seems the best way to have unmodified code (except for arrays inside arrays) preserving xml structural integrity.

should finish xml parser (weak,independant sax parser) in a few hours, then the generater for that, then onto embedded annotations (YACC hacking- easier than xml (surprisingly enough)(yay)) then i need to handle non-deterministic expressions (eek) and then the backend (easy (i hope))

all this by tommorow.

Arrrgh, Variables dissapear reapear its like wall paper, or perl programming or something. Maybe i should have written the whole project in ML, then i shouldn't be ashamed about the fact that i cant read my own code :)

Nose, Grindstone... Grinding nose sound.

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.
