Wanting to learn something.
I want to learn assembly programming. Not to actually use it that often, but to learn what goes on at a low level inside the computer. My current understanding is just that I hit "Ctrl+Shift+B" and Visual Studio farts out a program. I want a more in-depth knowledge!
For this reason I don't care about "High-Level Assembly" or any such tools that make assembler easier with HLL constructs. I want the raw, uncut, assembler experience! Any suggestions on what resources I should use to learn, and what assembler I should use? Thanks, uman

If you haven't already, get some material and learn how a "computer" system works. Then pick some processor, study its spec sheet, gather some material on its assembly language, and write something simple. The x86 is probably at your fingertips, so that's one possibility. You can write inline assembler with your C/C++ compiler, no doubt. You can also write some C/C++ code (or whatever language flips your skirt) and look at the assembler/machine code it emitted. If you want it REALLY tough, as in days of yore, before they blessed us with MUL instructions and such, investigate that LC-3 mentioned in another thread here. It's a simulated micro and there are "emulators" for it in Windows and *nix so that you can run what you write on your desktop. There's a sort of minimalistic editor and debugger for it. That one will put some hair on your chest because you're going to actually have to learn how things build up from the basics. On the other hand, the missing basic operations may represent somewhat of a side step, inasmuch as few, if any, real world processors are so limited.

Programming Groundup
Well, I believe this book is just what you need: Programming Groundup.
It is a book that would teach you how the computer works, how to think like a programmer and also teach you some basics of Assembly language. I am new to programming, but I took this book by recommendation from some guys from the #C channel at freenode for pretty much the same or similar reasons you mention, to learn how it all works deep down there and then more easily learn other languages with that base perspective already set in my mind. You can download the book here. Thx Daniel

I just gave it a cursory look, but the book looks pretty good to me. It's obviously going to be Intel and Linux centric to some degree, but that's all to the good so long as one remembers that it is e pluribus unum.

Sorry but what does "e pluribus unum" mean? I'm aware it is the motto of the USA but I've never heard it in conversation.

I'm curious: what does that actually mean?

Heh. I prefer to speak English except when I'm' being a pompous jerk.

And usually when I'm a trying to be a pompous jerk I leave out the extra apostrophes at the end of "I'm".
