Agreed, the XOR trick is just a clever trick that might be useful in some esoteric niche cases, but otherwise don't bother. GCC will even optimize away the XOR operations when this is used for simple things like ints on amd64. I did a

And in the old days people were accustomed to be able to resolve local hostnames, without having to supply any domain part. The "search" keyword in resolv.conf is a remnant of this. By adding a final dot, you ensured that the doma

I've had good experiences with ngircd. It's an IRC server that is very easy to self-host, and it can be installed via APT on any debian/ubuntu/raspbian etc system, and I'm sure on many others.

I'm not in the medical field either, but I remember they used niacin (a form of vitamin B₃) as an active placebo in the Good Friday Experiment[0] in 1962. The niacin doses produced some noticeable physiological effects, but it didn&#x2

I have stopped arguing about it. I just cynically observe the people who keep insisting that they have nothing to hide, and then watch them suffer the consequences of their own decisions.

I have the opposite experience, at least with regard to your first two paragraphs. Most of the things that I have backed up on other people's computers over the past 3-4 decades are irretrievably lost. But most of the things that I hav

I would like a more unified notation for the concept of "inverse". But I have no good suggestions for how to implement that. However, I have some bad suggestions just to illustrate what I mean: INV(*) x, instead of 1/x INV(+)

I agree, it's very irritating that so many people respond to who the messenger is, rather than to what the message is. You don't really have to anonymize the author's identity in order to focus on the message rather than the

If you do the key exchange face-to-face, all you need is some bytes from /dev/random for the key, and the cryptographic algorithm Data XOR Key. They can't outlaw the XOR operator and they can't "backdoor" all r

I look forward to the day when this is no longer the case. But we need to get better at punishing bullying behaviour to make this happen.

OK, I think I get it now. So comment macros saved from an earlier REPL session can be brought back for use later? That's pretty cool, and it does highlight the LISP roots of Clojure.

What does "save point" mean in this context? The concept is mentioned several times in the article, but I didn't see any references to saving anything.

You don't have to invoke color-blindness or tetrachromacy to explain that. Even normal trichromatic people will have differences of opinion about shades of blue or green. But every difference of opinion that might involve gender will a

Terminology is not always unambiguous. The spin quantum number is discrete for electrons {-1/2,1/2}, but spin also means the physical entity that gives rise to the so-called intrinsic angular momentum, which is a vector.

I too have had great experiences from doing recursive descent. I don't understand why so many people don't like it. The techniques for handling left- and right associativity of infix operators have been well known since many decad

It's even worse. Putin's failed attack on Skripal ultimately resulted in the murder of Dawn Sturgess[0] four months later. This was a case of using illegal chemical weapons on foreign soil, which puts Russia squarely in the same c

Yes. I just discovered that I have done it by mistake, twice during the past six years. I'll blame glitches on the trackpad on my previous laptop. I wasn't even aware of the feature.

Do you have any practical suggestions for how to accomplish that? I'm not rich, but I'm thinking that anything a billionaire can do with $1 billion can also be done by ten thousand households who have $100k each. So the middle cla

There are however google search results for "Happy people don't need to tell themselves they are happy, they just are". So maybe it transformed telling into asking, on a grammatical level?

I didn't find it rude at all. The comment that presented the link was pure click-bait. I prefer it when a brief explanation accompanies a link, especially when the link points to a 3 hour long video, as in this case. The YouTube teaser

Infinite sets are a useful abstraction, but uncountable infinities can probably be avoided since the Löwenheim-Skolem[0] theorem says that any countable first-order theory has a countable model. [0] https://en.wikipedia.org/

I got the same CAPTCHA, running Firefox 68.4.1 on Linux. Normally when this kind of thing happens, I just close the tab and move on with my life. But this time I tried opening with Chromium instead (version 76.0.3809.100) and then no CAPTCH
