The differential equations course was one of the most baffling experiences I ever had. The professor on the first day told us the course would be rote, as opposed to proofs, and every day he copied the methods to the chalkboard. He specific

> numbers (and other sorts of mathematics) do not pre-exist reality. Numbers are abstractions of regularities we see in nature. This is an open and ancient question. I don't suppose to have the answer. I will say, the case for mathe

There is an entire world here beyond registering for a signal that comment seems unaware of. Even the simplest of preliminaries: registering for a signal is arguably non-trivial and incorrectly specified in many places since sigaction() sup

It is true this improves the bad path. It ignores desired happy path cases: downstream processes, custom debugging, graceful shutdown, preserved workspaces, and so on.

The way exceptions are handled as a result of siglongjmp'ing out of a signal handler is currently platform-inconsistent and one of the many dark areas I alluded to. It isn't even consistent on Linux between compilers.

This conversation is silly. You are snapshotting the transformative window. If you snapshotted the internet in the 70s or 80s you'd get a much more mundane picture. I don't know if I think cryptocurrency will be as transformative

GC researchers insist on conflating GC with all of automatic memory management. The public doesn't do this and neither does the article. > Secondly, you know what's cheaper... Not doing anything at all. These techniques are on

Your comment is radically naive. You can't literally believe what a business writes in its PR spin. The only thing you can take away from this is that Visa intends to tip the balance towards merchants and away from consumers when it co

Your approach will not work. Either continue attempting proofs or give up. It's fine to read the answers after you've tried. > I've heard many many times that you can only learn math by doing it, which is certainly true ye

I don't know where this method of argumentation came from, but it's obnoxious and I'm over it. There are even soyjaks for this. Either you don't know and you're being lazy (I don't think this is the case), or y

Right, you are the cop-out I am complaining about. Linus is the premier figurehead of the premier open-source project. When a build tool he made for that project goes viral it isn't an accident. If it was anybody else's pet versio

Git's UI/UX is one of the worst engineering sins to be committed in the last two decades, and this website shows why. Literally nothing about git is intuitive and the "underlying model" is entirely ad-hoc. Instead of cel

The problem with concurrent computing is not a lack of Erlang awareness or message passing awareness. If either was the solution we wouldn't be having this discussion since they both pre-date the 90s. There ought to be a codeword where

I've written on this problem before: https://kevinlawler.com/parallel One issue is that the pthread model is too low level (think AND and OR gates), but you must include it for completeness. I agree with the comments h

I've run this experiment with friends and it was trivial to distinguish reds from whites with table wines. Whatever wines they use in these studies to stump experts must be more close in flavor.

Is Joel a supervillain? Why is Joel writing this and, given his obvious conflict of interest, addressing it to developers as if it were friendly advice, when it is not? I advise people not to work for Joel or his companies. This is develope

I think it is true. We head off discussion here by referring to the naive approach, but what you're doing is past naive coupon collector's and past the technical scope of the context. There are several steps where your method coul

If you can show that ancient placer deposits were the result of meteor strikes and not volcanic activity I'll change the article. Everything I read pointed to volcanic activity. If you mean modern mining activity, not germane.
