What is the scope of variables in JavaScript?

...@RobG It is highly rated because it is useful and comprehensible to a wide range of programmers, minor catachresis notwithstanding. The link you have posted, while useful to some professionals, is incomprehensible to most people writing Javascript today. Feel free to fix any nomenclature issues by e...

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'...

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. – Jerry Coffin Jun 29 '10 at 15:34 ...

When is assembly faster than C?

... 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 Getting the high part of 6...

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...

Hash collision in git

...t an interpolation of the entries for 32 and 48 characters lands us in the range of 5*1022 git commits for a 0.1% probability of a collision. That is fifty thousand billion billion different commits, or fifty Zettacommits, before you have reached even a 0.1% chance that you have a collision. The by...

Secure hash and salt for PHP passwords

...es entropy. Oops! Password entropy is approximated easily. Using the full range of ascii characters (roughly 96 typeable characters) yields an entropy of 6.6 per character, which at 8 characters for a password is still too low (52.679 bits of entropy) for future security. But the good news is: long...
