Divine Lunacy

Last year, my history teacher was “way to the right”, and he taught as such. Now, this year, my history teacher is “way to the left”, and he teaches as such. He can’t go five minutes without belittling bush, or bringing up Iraq. He even brought up the nuclear thing once. Is it too much to ask to just be taught without having views forced upon you? Being in that class gives me a headache; I just can’t stand to listen to all the hollow arguments, and feeble attempts at converting us all, though perhaps they aren’t so feeble. He probably has most of the class going! ugh!

So, we did matricies in school this week! More interestingly, we went over hill block ciphers. Penis gave me the idea to write a program to do them… So, I did. I made a matrix class in php, it is about 200 lines, including classes multiplication, addition and subtraction which extend matrix. ( I haven’t gotten around to inverse ). The arithmetic functions all work very well, but something seems to be going wrong in the cipher algorithm. Whenever I give it an enciphered string and the inverse matrix, it doesn’t completely decode it…. But I will get to that. It probably has something to do with how I am using the php chr() and ord() functions ( they deal with ASCII characters ).

Once again, a POW in geometry. They have all been pretty easy so far, and it is rather annoying me. Mr. Horne seemed kind of disappointed and shocked when I asked him if my answer was correct, before leaving school on friday. What, does he expect me to spend my whole week on it??? Is that why they call them Problems of the week? I always seem to mock that , and turn them into problems of the day! We should have one everyday, that would mean less time doing nothing.
