How do I create a Bash alias?
...
@Mischinab No, the file just needs to be readable in order for Bash to read it as its configuration file. Making it executable is technically harmless but unnecessary. I would discourage it on nontechnical grounds (you might end up confusing yourself and/or others).

Edit the root commit in Git?
...
Doesn't this mean that, in order for this to work, you need to have the foresight (or be psychic) to make an empty commit right at the very beginning of your project? This seems to be extremely situational, to me, and generally not practical. What do y...

What is the difference between a var and val definition in Scala?
...a number out of them. For example, if I have a queue with 2, 1, 3, in that order, I want to get back the number 213. Let's first solve it with a mutable.Queue:

Remove all the children DOM elements in div
...by references from other JS objects. For example: a gfx surface references all its children, a group references all its children too, and so on. Deleting just DOM nodes is not enough.
