Why is my variable unaltered after I modify it inside of a function? - Asynchronous code reference
...terday, the work I was doing required some information from a colleague. I rang him up; here's how the conversation went:
Me: Hi Bob, I need to know how we foo'd the bar'd last week. Jim wants a report on it, and you're the only one who knows the details about it.
Bob: Sure thing, but it'...
Why isn't `int pow(int base, int exponent)` in the standard C++ libraries?
...-1) for which underflow occurs, but the result is still meaningful in that range.

How can I reliably determine the type of a variable that is declared using var at design time?
...ample, method bodies are skipped if the kibitz token does not lie in their range - this is done optimistically, and rolled back if it skipped over the token. The equivalent of extension methods - class helpers in Delphi - have a kind of versioned cache, so their lookup is reasonably fast. But Delphi...
In C++, is it still bad practice to return a vector from a function?
...tually, you should never be "building a container rather than writing to a range." A container is just that -- a container. Your concern (and your code's concern) should be with the contents, not the container.

... predict precision loss). i.e. uniform absolute precision over the entire range, instead of close-to-uniform relative precision (float).
Modern compilers optimize this fixed-point example nicely, so for more modern examples that still need compiler-specific code, see

How does the ARM architecture differ from x86? [closed]
...egisters, eliminating predication from most instructions, and reducing the range of branches. At least in my experience, this still doesn't usually give quite as dense of coding as x86 code can get, but it's fairly close, and decoding is still fairly simple and straightforward. Lower code density me...

What is a reasonable code coverage % for unit tests (and why)? [closed]

Is the Scala 2.8 collections library a case of “the longest suicide note in history”? [closed]
...ot exactly known for its sophisticated type system. (Although it does have range types, which AFAIK pretty much no other language has, but that isn't really relevant here.) The other three languages I know are BASIC, Smalltalk and Ruby, none of which even have a type system.
