comment Is machine language always binary?
@prog: No; reading instructions one bit at a time and making decisions based on it would take too long, and CPUs are designed to be fast. When reading machine code, it's like Whatsisname said in his answer: the computer doesn't look at individual bits any more than you or I read by looking at individual letters. They're arbitrary numbers that map to values using an agreed-upon mapping. Sometimes the meaning of the machine code is hard-wired into the CPU transistors, and sometimes it's actually programmed in!

comment Is machine language always binary?
@Prog: Like I said, all numbers have a binary representation. 202 is 11001010, for example. But the 1s and 0s are an abstraction. Instruction #204 could mean "load a value from memory into a CPU register," for example.

comment What are the advantages of recursion compared to iteration?
When solving the maze, the recursive solution is only "perfectly clear" if there are guaranteed to be no cycles in the maze. Otherwise, it gets messy too.

comment Was there ever a serious push for partial classes in java
@CodesInChaos has it right. C# introduced a really bad feature (partial classes) so that they could do UI generation the wrong way. You would think, for a system that got started as a blatant ripoff of Delphi rewritten to look more like Java syntax, that they could at least have copied the basic concept behind Delphi's declarative UI system while they were at it...

comment What exactly is procedural programming? How exactly is it different from OOP? Is it the same as functional programming?
Procedural programming is not the same thing as functional programming; it's actually essentially the same thing as object-oriented programming, minus the objects and classes.

comment “Everything is a Map”, am I doing this right?
@EvanPlaice: Big-O notation can be deceptive. The simple fact is, anything is slow compared to direct access with two or three individual machine code instructions, and on something that happens as often as a function call, that overhead will add up very quickly.

comment What is the benefit of having the assignment operator return a value?
@MarjanVenema: I believe what he means by that is, Pascal's := operator is not only "different from the equality test operator" like C#'s is, but it is also not likely to be confused with it, which is a chronic problem in the C syntax.
