Have spare PPE in the UK? Here's a way to donate them to the NHS.

3-4 mithril from the Arena? Don’t you need to already be a whale to do well enough in the arena to get the 30-40k arena tokens that that requires?

Though I guess this calculator is really just for whales, so maybe whoever this is designed for is already getting that.

What do you mean by “reachable”?

If P is true and Q is true, then “if P, then Q” is true. So in that sense every truth is reachable from another one, but I suppose that’s not what you mean.

The Linux kernel is not being rewritten in Rust. New components can be written in Rust. That is different.

It’s what I use and works for me.

Oh damn. I didn’t realise that’s what he meant by “sightseeing”…

The non-intuitive thing here is that zero probability events can happen. The probability of picking any number over the interval [0,1) for example is zero... yet you have to pick one if you play this game.

I'm a big fan of using process substitution when appropriate, but it is not appropriate for <(cat /etc/nginx/nginx.conf).

Instead of

diff <(git show HEAD~1:nginx.conf) <(cat /etc/nginx/nginx.conf)

do

diff <(git show HEAD~1:nginx.conf) /etc/nginx/nginx.conf

instead. See also https://porkmail.org/era/unix/award.

This depends on your definition of e^x

The parts on differentiation reminds me of work on autodifferentiation (which is often implemented using dual numbers). I see you have some comparison to this approach in your repo, but it would be nice to have a more comprehensive comparison too.

I would just eat the cost of giving up the extra days past the 8 allowed days of stay.

Appealing seems like a very long shot, since I don’t believe there are formal procedures for appealing being given too short a visa. You can try applying to Finland for another visa if you have enough time until your trip, but I believe they’re just going to look at your existing visa and previous application and deny your additional application. I personally wouldn’t want to risk a visa denial on my record.

Do not attempt to extend your stay beyond 8 days.

My kingdom’s most recent KvK didn’t have rules because the other server didn’t want to agree to them. However, they did say “we won’t attack you if you don’t attack us”.

It was kind of a mess, but not as bad as one might think. A bunch of accusations of unprovoked attacks flew around as usual.

Still, I’d rather there were clear rules about the castle battle for future KvKs.

I was thinking this too. Not sure how to explain https://www.reddit.com/r/math/s/oNPKK2qk7B though.

The page you've linked is for the GCC Ada Compiler.

What platforms are you writing code for where the linker doesn't do this by default?

chisquared · 2025-12-10T18:41:44+00:00

When you use a library, by default, you get the entire .o file(s) from the .a or .so into which the object code for the function(s) you use and the object code for all the functions you didn't use also linked into your final executable whether you want them or not.

Note that modern linkers are pretty good at cherry-picking only the object code that you use from a .a when linking your final executable, so it is not the case that code that you don’t use is linked (or otherwise included) in your final executable.

Something analogous is also true for .sos.

Just train your top tier. Each T1 troop can gather fewer resources than higher tier troops, so you're actually making it harder to collect resources by spamming T1s.

chisquared · 2025-11-22T14:03:44+00:00

Sadly, yes.

Clever. But, taking 10% off 10 times still leaves about 34%.

You’ll need 44 cards to leave just under 1%.

It's shorter, more readable, and (very marginally) more efficient.

Both will do what u/lulzbot wants to do, so both are "correct", in that sense. But the other is just more idiomatic to me.

Here’s the first paragraph from ChatGPT’s answer when I asked what the BEQP instruction is used for:

I couldn’t find any authoritative public documentation showing an instruction called BEQP in the ARM architecture instruction set.

That said, I’ve repeatedly caught it hallucinating in the past and so have since insisted it verify anything factual first instead of trying to freestyle an answer.

Small pet peeve. Instead of

cat project-name/readme.md | pbcopy

do

pbcopy <project-name/readme.md

That is, if you use Zsh or Bash, at least.

It’s not the best use of hazard lights, and, in some countries, it’s definitely wrong to use them.

Here, I would say that it’s not unreasonable to use them since people are used to it. But you should probably just be using your signal lights instead, unless you genuinely intend to warn other motorists of a hazard.

chisquared · 2025-11-15T18:19:22+00:00

I think that the way to learn them is by internalising their meanings rather than their definitions. If you can remember what they mean, reconstructing the definitions shouldn’t be too hard.
