comment Greenfield vs. brownfield revenue? (attempting to get an idea of measure of effort expended on the two)
dunno, reddit maybe? And if you just want to check wages, I'd just recommend looking at Glassdoor.com

comment Greenfield vs. brownfield revenue? (attempting to get an idea of measure of effort expended on the two)
I don't think this is good question to ask here. This is more like setting topic for discussion rather than answerable question. See programmers.stackexchange.com/help/dont-ask Questions asked here ought to be "practical, answerable questions based on actual problems that you face".

comment Algorithm to pick user
@maxpolk: how do you figure O(1)? it's O(R) where R is the sum of all ranks.

comment Algorithm to pick user
@DocBrown: I can imagine some kind of B-tree, where you'd do O (log(n)) recalculations rather than O (n) on update/insert/delete.

comment Algorithm to pick user
@DocBrown: question is clearly about algorithm, not about code for quick-dirty hack.Thus this answer is wrong, because this is not the correct algorithm.

comment Algorithm to pick user
-1: it's an easy hack, but it's way sub-optimal if the ranks are higher than single digits.

comment Do I need to return error: null in JSON response?
@JanHudec: 400 is any bad request, doesn't matter if it's malformed HTTP, a syntax error or just request that doesn't pass the validation. Using 400 in this case is for example the standard way as described in the "RESTful Web Services" book

comment Do I need to return error: null in JSON response?
@JanHudec: actually the 403 here is wrong. For bad parameters you should use "400 Bad Request".

comment At what size of data does it become beneficial to move from SQL to NoSQL?
@johannes: Sorry, but you're just wrong. There are certain thresholds beyond which simple techniques as scaling up do not work anymore. SQL RDBMSes are quite versatile, but they are no silver bullet.

While it's true, it's not the answer to the question asked.

comment At what size of data does it become beneficial to move from SQL to NoSQL?
@johannes: you say terabytes, which is like less than a half of one commodity HDD. OTOH, I've worked with petabyte sized NoSQL solutions, and in the world of Big Data that's rather small, big players like Google, FB, Amazon or NSA deal with yottabytes.

comment Why is Quicksort called “Quicksort”?
Timsort, which is improved quicksort, does not take name after how it works, but rather from it's inventor. Names like flashsort or introsort don't tell you much about algorithm either.
