Serious question, if a little philosophical.
If you look back at big personal decisions you've made in your life that turned out right in retrospect, what's an accurate way to describe most of them?
A — I made them quickly.
B — I mulled over them for some time, and modified my thoughts, so what I eventually decided was better than my initial hunch.
C — I spent a long time thinking about them, but in the end I went with something that largely matched my initial hunch.
Boosts appreciated!

If you're an English native speaker, do you ever use the word "minute" as a verb¹ to mean taking notes at a meeting?
A — I do
B — I would use the word, but that context normally doesn't come up in my life
C — I would not, because that meaning is archaic
(Boosts appreciated.)
¹ Emphasis on "as a verb". An example sentence would be to say "could you join us to minute the conversation?"

That's about my ballpark too. One 4 with the PoE+ HAT (with fan), another 4 in the Argon Eon case with 2 HDDs (with a case fan). That seems to be about 20°C above what others report; any idea why our devices get so hot?

Okay folks I would appreciate your help here.
I have purchased an unmanaged PoE+ switch (TP-Link TL-SG1008P, seen in link below), and 2 rPi PoE+ HATs.
One of my Pis is an rPi 3, the other a 4; both should be fine with the HAT.
Neither draws power from the switch PoE port. I have tested several cables; sadly I have no other PoE devices to test with.
When USB powered the Pis do fine. The fan on the HAT spins, so I think it's installed correctly.
What do I check next?

Question for people from North America: have you ever demanded, or witnessed someone else demand, a free meal at a restaurant because as a result of a complaint (a.k.a. expecting a meal to be "comped")?
I'm led to believe that such an occurrence is not uncommon in your neck of the woods — but I struggle to believe that this is actually so. Here, such a demand would be considered ridiculous. Sure, if the cook botched one of your dishes you might get it remade, but you'd still pay for it.

33 years ago today, Freddie Mercury died.
I'll always remember November 1991 for two things: Earvin "Magic" Johnson's retirement from the NBA because he was HIV positive, and Freddie Mercury's death from AIDS.
When Freddie found out he was HIV+, like many others, it meant practically certain death within a decade.
Magic is alive and well, like many others, nearly 3½ decades on.
That is an incredible achievement of human medicine and public health.

Any physicists around who can help me understand something?
How should I picture neutrinos in a QFT context? If particles are ripples in their field, and we can detect only a teeny-tiny fraction of neutrinos, what does that say about their field? Is it somehow quiet, and only ripples when we make a chance detection of a neutrino? Is it constantly rippling, but so noisily we can hardly ever detect a signal in it?
Or have I got this all wrong?

Another question primarily for the native English speakers.
In German, the expression "Papier ist geduldig" (literally, "paper is patient") means that just because a rule is written down, doesn't mean anyone is following it.
It is commonly used as a sarcastic comment upon learning of a new rule, law, or norm that the speaker believes will never be properly enforced.

When I do talks, my complete slide deck is available with speaker notes for people to open on their own devices, where the slides advance in sync with what I present on the main projector. I think of this as an essential accessibility feature for people with impaired vision.

Pet peeve: when people dunk on things they don't like, without considering that the alternatives are worse.
In our latest stupidity craze, apparently QR codes are now evil.
Look, "normal" URLs are a fucking pain. That's why we came up with link shorteners. Those are now grossly enshittified advertising profile building machines. Yeet them.
QR codes are infinitely better.

Took the ol' road bike out of the shed.
Every bit of this machine is replaceable or repairable by a moderately talented person. It requires no electronics, electricity, or fuel to run. All it needed after years of disuse was a wash, some air in the tubes, some grease on the chain, and two screws on one pedal tightened. It rides exactly as it did when I bought it off my first salary, nearly 30 years ago.
Bicycles are engineering marvels. Hardly ever has humanity come up with anything close.
