i had a nice long fat juicy hot dog with mustard, ketchup, and relish for lunch. yummmm.

good grief!

i hate it when i get my cravings for particular foods and gotta satisfy it. i had to have greasy food today, and was so so hungry. maybe the fact that i have been working out harder, is making my body want more calories, i'm not too sure. but i did do a good run on the treadmill today ! i am building up

let's see if my webcam will upload its image now

success, my webcam is back online!

it's not a good sign when the first problem takes you a half hour to do and after much frsutration. i will admit, that was a t-r-i-c-k-y problem. i think professors should always start the semester with very very easy problems to build up the student's false sense of security and possible self-esteem. twas not the case now.

well i can't go home tomorrow. it blows. i can't get my new cellphone, i can't get my supplies, fuccck! i have to hunt down the professor and get help on one of the problems. i've spent too much time on this already and am not getting anywhere. i'm going to have to get help thursday morning or afternoon whichever time i can catch him. this just blows

ok, i am going to e-mail the prof and call him in the morning asking what time I could come in thursday to get help on the last homework problem. i've spent way too much time on it! then i will take a playstation break to cool off and then start something else

fun little program for Matlab in my textbook that generates pseudorandom key widths computes some statistics. i enjoyed the refresher on Matlab.

%Program for generating N key widths
N=input('Enter the number of key widths to generate:');
w=input('Enter the nominal width (mm) for the keys:');
p=input('Enter the + or - uniform variation (mm) about the nominal width:');
flag1=input('Enter 1 if all widths are to be displayed; otherwise enter 0:');
flag2=input('Enter 1 if histogram is to be displayed; otherwise enter 0:');
X=rand(1,N);
W=w-p+2*p*X;
mu=mean(W);
std_dev=std(W);
disp('Sample mean and standard deviation of key widths:');
disp(mu)
disp(std_dev)
if flag ==1
disp(' Thw widths in mm are: ');
disp(W')
end
if flag2 == 1
hist(W), xlabel('Key width, mm'), ylabel('Number of counts')
title(['Distribution of ', num2str(N), ' key widths '])
end

so cute, they're my pound puppies
