If that's your position, then HATEOAS is equivalent to REST. Because I can implement everything Roy Fielding envisioned except for that single top-level resource discovery URI and all of a sudden, I'm 100% RPC and 0% REST. Why bother with the name REST then, if you consider HATEOAS to be equivalent? It seems that HATE...

I've only done some surface research regarding cloud vs. traditional, so I don't know much.

I think prettiness was the wrong word. It's about simplicity, consistency, separating the format from the resource, and separating the operation from the resource identifier (commonly the URL). So many URL schemes that follow this are pretty, but that's orthogonal. Programmatic discoverability is the ultimate benefit, ...

That was a really fun exercise, I don't do much C/C++, but it was fun to think about optimization at this level and what the compiler could try to figure out (I also sided with GCC being able to figure a lot out being as I hear good things about C compilers now).

Programming is the shiz. Also, C/C++ is really the way to go because it's just above the metal and allows great flexibility and if you don't want to work in the low-level stuff, you don't need to; it's flexible to function at a level almost as high as Java/C#/Javascript/PHP in C++11.

I'm not sure what you mean by "that type" of windows server. *I* don't use Linux because ASP.Net MVC 3 support isn't 100%. However Amazon does have Linux servers available for similar (usually cheaper) pricing structures so I highly recommend them as well if they suit your needs.

Any time someone poses a question like this, you should immediately expect it to be mostly a trick question, and answer "counterintuitively". I don't know hardly any C and no C++ at all, but I expected this to be one of those "I bet you didn't know GCC did this!" posts, and was completely correct.

C/C++ is really NOT the way to go... Most of the stuff C++ adds to the table in regards to language features is deceptive to language newbies. For example... Templates: Sure, yes, it looks like actual generics, but in reality C++ is copy-pasting your code behind your back and this makes debugging a lot harder than it ...

It is smart enough to do that. If the array is modified in the loop the compiler won't pull strlen() out.

I think it knows that as long as no nulls have been added or overwritten, strlen returns the same value. Then again, I'm a fan of Haskell, so this all seems cheap and dirty to me.

It doesn't really need a "cheat-sheet", per-se. When you use the GCC builtins, it knows the body of the function and how it behaves, so it can perform optimizations as if the function was inlined.
