Why not use double quotes for strings in all languages? It makes sense for a number of reasons. Single quotes are much more likely to be in the contents of a string than double quotes. Of course, if you have a style guide, you should stick

Actually that's also wrong, I usually see this rule applied in other languages: If the opening bracket is on the same line as content, then so is the closing bracket. By this rule, we have two options: (+ (EXPT 23 2.4) (S

Treap: https://en.wikipedia.org/wiki/Treap It's like a Red-Black tree in use case, but much faster to implement, which is good for competitive programming. The average case complexity is the same for all operation

An alternative might be for personalisation to be opt-in rather than opt-out even when signed in with an account (which shouldn't even be necessary for many services anyway)

Go enforces 1TBS over Allman style braces IIRC. I don't really care because I like 1TBS and also don't write Go but it did enstrange parts of the community.

Instead of using upvotes from sites such as Reddit and HN, why not instead allow the users of the search engine itself upvote and downvote results? This might allow quality results outside the scope of larger online communities to still be

I just use a Python or Node shell as a calculator. It usually works well enough.

This is basically exactly me, except I don't have as concrete of a feel of the actual shapes, all I know is that 9's slice off ones from other numbers, not that actual shape of the number that allows it to do wo.

Priority queues aren't constant time. They're log time.

If it works, it works. Priority queues are an extremely powerful data structure if you leverage them right. I find C++'s set and map and related data structures are also very useful for solving cp problems.

I often feel something along the lines of this as well. I often feel like no matter how much effort and energy and passion I put into something, nobody will care. It's like screaming into the void. If almost nobody sees this comment, w

Marking questions as "stupid, irrelevant, lazy etc" is SO's way of maintaining site content quality. Though they do get a bit aggressive at times, it's actually a good thing. A site without that just turns into Reddit. A

Note: don't use typeof x === 'object' to check whether something is a valid object, because it will return true for arrays as well. Arrays are objects, so this is expected behaviour.
