I had almost completely forgotten about this diary (you see my brain does work, honestly it does)

PhDing in bath, as well as working once a week at the work thing, which keeps the wolves from the door. Since the last post i have developed minions, very scary.

living in Bath (most americans seem to of already visisted it and are welcome to, if the could just not do it on my lunchbreak)) with Emma.

Despite my lame excuses for not coding as much as i want to , i have managed to get tied up with another project, which is all very pre-alpha at the moment.

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.

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

AAAAAAAAAAARGH.

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)
<!!boom!!>

this is like beating your head against glibC untill it bleeds bits....

i wonder what happens on solaris...

Program received signal SIGSEGV, Segmentation fault.

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

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.
