    "This is impolite" is not a truth statement, it is a value judgment. It can be impolite to do something even if someone has said that they don't mind.

    There are a few confounding factors here: 1. It may be legally permissible, but it is impolite, to change the license away from the well-known Apache software license towards somet…

    This seems like too much effort has been put into it for it to be a purely satirical exercise, but I really cannot see why anyone would prefer to use this within Python, rather tha…

    Describing something in the imperative voice doesn't make sense. Why would you ever say "TL;DR perform this action" instead of "TL;DR performing this action", when trying to descri…

    No? It's in the imperative voice, it wouldn't make sense to read "do this" as a description of an antipattern.

    That's older than the median age of a human being. Granted, people don't tend to play games before the age of about 7, but that still seems suspect.

    Then a very recent _increase_, even beyond that, is notable, no?

    Sorry, but no. Edmonds clearly maps "efficiently-solvable problems" onto the notion of P in a complete way, not only as a subset of P.

    P vs NP is not an "in practical terms" question. It is a theoretical question with theoretical definitions of theoretical terms, including "efficient", which directly corresponds t…

    > Even a P=NP result doesn't tell us that NP problems have efficient solutions. Yes it does. That is literally exactly what it means. The class P is the class of problems which are…

    The value of purely functional programming languages, as opposed to functional programming languages like lisps, is that you get referential transparency, which means that when you…

    Subtraction is truth preserving on the sign bit. It's not truth-preserving in the actual subtractive bits. (I disagree with their claim that the subtractive bit is functionally com…

    Technically speaking, batteries do get lighter when discharged! But not in any useful way, and entirely unlike the situation with aeroplanes, of course.

    That's not really fair. systemd does a lot more, and with good reason (among other reasons: there are many, many economies that can be made when "booting" and "managing" services h…

    It's a term of art from the community, that also draws in the intellectually curious with a "wtf is half an A press?" - it's an excellent title.

    Actually , if you start working out which one is the next to run, you have reinvented selection-sort and you are no longer linear time. (Hence why this is not a sensible sorting al…

    Godot is a super impressive piece of kit. I'm waiting for a reason to start a new game project so that I can get to grips with it more firmly, but what they've been able to do with…

    This is a great point! In order to find out, perhaps we should engage some experts at a leading research institution to do some wider studies that are able to account for such fact…

    I fail to follow your chain of reasoning. How can the claim both be "clearly false" and unclear in its statement? The use of "should" as the very first line of the body text actual…

    Wholly dependent on what you mean by "took off" but I'd argue Haskell qualifies. It was a nothing language for two decades before finding its footing and is now used in quite a lot…
