So I've been working with MIPS assembly recently and you've inspired me to try some of the PE problems with it. I solved the first two, but I've run into a bit of a problem in that the assembler I'm using doesn't actually have all the MIPS opcodes built into it and I'd really like to be able to use bitwise logic operations so I might have to find a new assembler.

oh shit of course he has to show up

at least i can still beat lawlz and jmv  baddood;

so im on problem 3 and i think i did it right after some help on factorization and lists since i never used them.

now my code is taking a long time to run i hope it works ^___^

You've solved like twice as many PE problems as I have. akudood;

I actually did most of the problems I've done sometime last fall in Scheme.

Assembly isn't that bad for the easier ones, but it gets really messy when you need anything complicated. Function calls are horrible because you have to handle all the memory allocation manually.

because lack of actually doing the programs because I don't care enough = lack of ability. psyduck;

laziness and the vidya and a highly irregular sleep schedule  that keeps me from ever being able to focus and apply myself to anything

And if anything, JMV should be the "professional" here since he is (or was) studying to be a computer scientist. I just slowly picked up Python over the summer. :O

#Find the last ten digits of the series, 1**1 + 2**2 + 3**3 + ... + 1000**1000
result = 0
for i in range(1,1001):
result+= i**i
print str(result)[-10:]

Because knowing one language makes you a professional in every programming language.
Write a compiler for Java so you don't have to use the JVM, since you know python and that makes you a professional in any language.
Also, as you said, my problem is:
