02:34 pm - Felony Snowball Charges
http://www.thesmokinggun.com/archive/years/2010/0209101snow1.html

Felony snowball throwing charges have been leveled against two Virginia college students for allegedly pelting a city plow and an undercover police car during Saturday's blizzard.

Five years for throwing snowballs at a cop car. That's more time than some people receive for murder in this country.

PWNed!

I guess throwing those two games so Peyton could "rest up" worked out well for you.

04:58 pm - Brian Greene's _The Fabric of the Cosmos_
I finished reading this book, after a year or three of trying to slog through it. I didn't enjoy it much, not nearly as much as I liked his previous book _The Elegant Universe_. It felt like the textual equivalent of chewing gristle. I don't know if it's because I am so close to the subject now, or what, but there you have it.

02:01 pm - Natalie Imbruglia - Want
All that you want
I hope you get all that you want
I hope you get all that you want

So I suppose you got what you want
Take a good look at what you give up
Because I’m telling you
A heart can’t be unbroken oh, oh, oh, oh

And can you remember how I kiss you
Recall the sweet taste in your mouth
Cos baby the memory is all you get now
And I’m moving, movin, moving on

All that you want
I hope you get all that you want
I hope you get all that you want
Cause I do
I hope you get all that you want
I hope you get all that you want
Cause I do

Does every morning make you happy
And tell me do you laugh yourself to sleep
I hope you find it easy to forget me oh, oh, oh, oh

I hope you don’t feel anything when you see me
I wonder if you’re out there having fun
I hope you get all that you really wanted
Cause I’m moving, movin, moving on

Don’t you see the light has changed
And nothing looks the same
Just shadows on the ground
And if you listen carefully you’ll hear

All that you want
I hope you get all that you want
I hope you get all that you want
Cause I do
I hope you get all that you want
I hope you get all that you want
Cause I do

11:07 am - This sucks
I couldn't sleep a wink. I guess the plus side is that I'm not yet sleepy.

02:58 pm - Project Euler, Problem 9
http://projecteuler.net/index.php?section=problems&id=9

There exists exactly one Pythagorean triplet for which a + b + c = 1000.
Find the product abc.

I approached this two ways. The first way was a purely bruteforce method. Run through a lot of a's and b's, calculate c, and if a+b+c=1000, print out everything. This results in a lot of non-integer c's getting created and then the user has to sort through the results to find the right c. It was easy to code, and is behind the cut.

I remembered though, somewhere in my memory, that there was a formulate to generate Pythagorean triples. A quick trip to wikipedia and I had Euclid's formula for doing the job. So I rewrote my code to use that, and voila! It spit out the right answer.

09:45 pm - Nick Cave and the Bad Seeds - Moonland
When I came up from out of the meat-locker
the city was gone
the sky was full of lights
the snow provides a silent cover
in moonland, under the stars
under the snow, I followed this car
and I followed that car, through the sand
through the snow, I turn on the radio
I listen to the deejay, and it must feel nice
it must feel nice to know, that somebody needs you
and everything moves slow, under the stars
under the ash, through the sand
and the night drifts in, the snow provides a silent cover
and I'm not your favourite lover, I turn on the radio
and it must feel nice
o very very nice to know, that somebody needs you
and the chilly winds blow, under the snow
under the stars, the whispering deejay
on the radio, the whispering deejay
on the radio, I'm not your favourite lover
I'm not your favourite lover, and it must feel nice
to leave no trace (no trace at all)
but somebody needs you, and that somebody is me
under the stars, under the snow
your eyes were closed
you were playing with the buttons on your coat
in the back of that car
in moonland, under the stars
in moonland, and I followed that car

I solved this in a somewhat non-elegant manner. I took the 1000-digit number, and broke it up so that only one digit was on any given line, then saved that to a file named "number". This is because I didn't want to go look up how to get FORTRAN to read one digit at a time out of a string or something. Then I read that number in, run through the whole thing multiplying and checking against the previous biggest number. Pretty simple aside from the finger cramps of hitting the left arrow key and enter 999 times.

04:24 pm - Project Euler, Problem 7
http://projecteuler.net/index.php?section=problems&id=7

What is the 10001st Prime number?

To do this problem, I took the prime factorization routine from Problem 3 and added a line in it that counted the number of prime factors for a given number. If that counter was only 1, then the number in question is itself a prime number. So the factorization routine became a prime test routine. Add in a little wrapping to loop up to the 10001st prime number, and we're set.

I think the execution time was fairly long, but I freely admit my code is less of an optimal method and more of a "Well, it works..." one.

[efeger@zanzibar problem_007]$ time ./a.out > answer

real 0m23.407s 104659
user 0m20.421s 104677
sys 0m0.068s 104681

A better program should be able to do the calculation in about a second or less on my computer.

07:58 pm - Tropico 3
Man, I wanted to check Tropico 3 out like since the day it first came out. I didn't want to pay 40 bucks. But then today Steam put it on sale for 14 bucks today. I couldn't pass it up. They also have both Freedom Force games, and all 5 X-COM games on sale for 2 bucks a bundle.

I'll report back later if I like Tropico 3 or if I hate it.

04:20 pm - Project Euler, Problem 6
http://projecteuler.net/index.php?section=problems&id=6

Find the difference between the sum of the squares of the first one hundred natural numbers and the square of the sum.

This is easy. I could compute it by hand if I wanted, but this is exactly the sort of problem which FORTRAN is made for. See the code I ran behind the cut:

One note is that Project Euler didn't like the minus sign in front of the number, so throw it away. Alternately just reverse the order of the subtraction in the write statement. Piece of cake.
