Is it good style to explicitly return in Ruby?
... as an answer.
TL;DR - You don't have to, but it can make your code a lot more clear in some cases.
Though not using an explicit return may be "the Ruby way", it's confusing to programmers working with unfamiliar code, or unfamiliar with this feature of Ruby.
It's a somewhat contrived example, bu...
What's the difference between HEAD^ and HEAD~ in Git?
... usually what you want
Use ^ on merge commits — because they have two or more (immediate) parents
Mnemonics:

What does “abstract over” mean?
... = as.foldLeft(z)(f)

}
trait Foldable[F[_]] {
def foldl[A, B](as: F[A], z: B, f: (B, A) => B): B
def f...

...y, into one action, is surprising to humans who read the code and makes it more difficult to reason about program behavior.
Other languages have essentially come to the same conclusion. Haskell briefly flirted with so-called "lazy IO" which allows you to iterate over a file and have it automatical...
How do I get an object's unqualified (short) class name?
...r of a certain class, the way to test it is with instanceof. If you want a more flexible way to signal certain constraints, the way to do that is to write an interface and require that the code implement that interface. Again, the correct way to do this is with instanceof. (You can do it with Reflec...

Is SHA-1 secure for password storage?
...-3 round-2 candidates appear to be faster than SHA-1 while being arguably "more secure"; yet they are still a bit new, so sticking to SHA-256 or SHA-512 would be a safer route right now. It would make you look professional and cautious, which is good.
Note that "as secure as you can get" is not the...
