### Re: Sizes of Infinity

I guess the quickest thing I came up with offhand is this: f(n) = -2n for n<0 f(n) = 2n+1 for n>0 or n=0 This maps the positive integers (and 0) to the odd positive integers and the negative integers to the even positive integers thus all integers are mapped to the set of positive integers and vice...

### Sizes of Infinity

I have a question about the sizes of Infinity. I understand that the set of all decimals is larger than the set of all natural numbers. But I've heard two conflicting arguments about the size of all Integers vs the size of all Natural Numbers (or Positive Integers). Some say that there is a Bijectio...

### Re: Python 2.x vs. python 3.x

Python 3, all the way and unreservedly. That being said, it won't fully happen until systems ship with python 3 by default. And systems won't ship with python 3 by default until they know the programs they rely on are compatible with python 3. It will happen (soon I hope) but it's going to take some...

### Re: High-Base compression

Thanks a bunch everyone! Your answers basically confirmed what I was thinking (possible, but not very useful). And thanks for the resources for further learning, too.

### Re: High-Base compression

Yes, I realize all of that, but I must not have explained myself well. So I spoke to a professor about this and got some more insight which might help me explain this better: To have enough single characters to be able to represent every permutation of a series of say: 64 bits, you need a 64 bit cha...

### High-Base compression

The thought occurred to me recently that there might be a way to compress files by converting large chunks of binary sequences into ultra-high base encodings (say base 256 or higher). Just as 1111 in binary can be converted to a single f in hexadecimal, I wondered if there was a point at which you c...

### Re: Superuser: "What are the Windows A: and B: drives used f

It's odd, I'm under 25 but I keep realizing that my computer experience is not the same as most of my generation. My fist computer experience was on a 386 running MSDOS & Windows 3.1. I can still remember when my father upgraded us to 3.11 and when we bought our first Pentium so we could run Win...

### Re: Tic-Tac-Toe Forks

Thanks for the information guys, this helps point me in the right direction. I realize that Tic-Tac-Toe is one of the Simpler AI problems to solve, but I'm a n00b at this stuff. This comes as part of an extensive study of the game as it applies to computers for my Computer Information Technology 499...

### Tic-Tac-Toe Forks

So, I'm trying to write my first game AI and have it play Tic-Tac-Toe. I'm following the basic "perfect game" algorithm and am trying to have it test for possible "Forks". Or in other words look to see if there's a place to put a mark that will lead to a situation where two possi...

### Re: 0264: "Choices: Part 1"

So, I recently went back and read this comic, and all I could think of was Amy Pond's Crack in the Universe for Dr. Who. It's even the same shape. Anyone else?

Wow, this is some great information. Thanks to all of you for helping shed light on this for me, it's funny how much you can learn from a little curiosity. Thanks especially to EvanED & Derek for giving the mathematical explanation why computers struggle with this. And thanks for introducing me ...

### The 2^2^2^2^2^2 Problem

I brought this up in the IRC channel a few days back and had some interesting feedback, so I thought I'd try it here. I'm a CIT major and Math minor at a 4-year college, getting ready to hopefully go on to a graduate CS program. Here on campus we have a UNIX society where we get together each week t...

### Re: Is Java is a bad language for beginners?

OK, I'll dive in too, (why not). Java is a great language for beginning Object-Oriented Programming. However I would not say it is the best for starting out in general. I also don't feel that BASIC is the best beginners language (although I started out on QBASIC, myself and still feel fond of it). I...
