Ugh ..... today's going to suck. Just got back from econ and now I have two homework assignments due tomorrow, and a quiz I have yet to study for at 1:30.

back from operating systems quiz, it was more like a midterm ... pretty rigorous. anyway, i finished most of my digital design homework earlier this morning, so now i just mainly have my formal models homework to do (which is the worst.... tons of proofs about boring shit.) oh fun.

if any good windows programmer out there knows how to make a global (system-wide) accelerator key (shortcut key) that sends a message to an HWND, let me know.... I've read all this, but it doesn't seem to address how you'd insert an accelerator table into the system's PreTranslateMessage loop. i want LiveJournal to be able to open with Control-Shift-L like ICQ opens with Control-Shift-I, even when the dialog/frame doesn't have the focus. ICQ's window title for editing their keys is labeled "System Shortcuts", which may be a hint (given that ICQ's UI is made by the programmers, not a smart user interface team.....). even if you don't know, please copy/paste this journal entry to programmer friends of yours and have them email me at brad@livejournal.com if they know how. i'd love you forever. :-)

new version of livejournal for windows is available here which fixes an obscure (but annoying) bug. read the web page for more details. thanks to Benjamin Keller for finding it. this is why we have beta periods. :-)

oh yeah, back to my homework that I have no clue what to do on.... :-/

LOL!!! So Erik walks in here and says..... "You know Eli, I was thinking of you today when I got in the shower----" LOL, and then Eli and I start busting up laughing. He then went on to explain himself, but we all know he's gay. ;-P

Stuff I don't care about:

Problem 1: 2.3.1 (83)
Imagine you have an NFA N(L), and then you do the subset construction to find the equivalent DFA D(L). Now, the final states of D(L) are any states which in their set contain at least one final state of N(L). If you then invert the states, the final states are any node which does not contain a final state of N(L), and this exactly what we want. However, let's see what happens if we try the naive way to invert the NFA N(L) by flipping all the states. Let's call this inverted NFA ~N(L). The final states of ~N(L) are now the old non-final states. Now, if we go to take the subset construction of ~N(L), the final states of ~D(L) are any node which contain at least one non-final state. However, there's nothing saying that the final states of ~D(L) can't also contain final states. Thus, inverting the states of an NFA do not create the complement, else the equivalent DFA of the inverted NFA would have its final nodes all consisting of sets that were previously entirely non-final.

going up to scott's for a bit. sick of homework. he's sick of it too, he's programming... i'll watch him, maybe bring my book and think about studying.
