jstanley··on Dear people who work at the airport
Easy to fear what you merely imagine.

Did you know that for train and bus travel in the UK bags are not scanned? And we don't have people bombing trains and buses all the time.

Some museums look in bags and some don't and I'm not sure there's a statistically significant difference in how frequently they get bombed.

Do you even have crackheads in London? I was familiar with "crackhead" only as an American concept.

> The numbers are as good as they can get

That doesn't mean they don't warrant error bars.

Error bars aren't there to show that you didn't do a good job collecting the data, they're there to show your level of uncertainty.

Do you have an encyclopedic knowledge of which terms are regulated and which ones aren't?

Don't you think it would cause more confusion if people expecting to buy a Jamaican beef patty instead have to buy a "Jamaican beef-inside-pastry product" ?

std::array isn't a thing in C, so you don't.

> * measurements, when executed correctly, are objective with numeric evidence, thus some people are wholly incapable of measuring things for the same reasons some people cannot introspect

I don't understand what you're trying to say. What are the reasons some people can't introspect? Is it even true that some people can't introspect?

No, I think before I speak and say what I planned to say. What do you do, sir?

jstanley··on Discovering Cryptographic Weaknesses with Claude
It's so bizarre to me that people want to do this.

Can't you type faster than you speak? Doesn't your speaking inhibit your thinking? Aren't you self-conscious talking out loud? How are our experiences so different?

jstanley··on How Unix spell ran in 64 kB of RAM (2025)
> giving each hash function it’s own bit table is equivalent to having one bit table with a number of bits equal to that of the sum of the numbers of bits in each hash function.

This is incorrect, although I also initially had the same incorrect intuition, see my (downvoted) comment in the same thread.

By way of illustration: imagine the limit case where you have the same number of bits as hash functions, so there's only 1 bit per hash function. If you have a separate table for each hash function then every input hashes to the same thing so all inputs are indistinguishable.

But if you put all hash functions in the same table that has a number of bits equal to the number of hash functions, then each hash function only sets 1 bit chosen at random based on the input, instead of always setting the same one.

jstanley··on How Unix spell ran in 64 kB of RAM (2025)
Seems to me that as long as the total number of bits is the same it makes no difference whether each hash function has a separate table or not.

EDIT: Although, https://chatgpt.com/share/6a67336b-8600-83ed-9671-fab769b485... - it is in fact ever so slightly less effective if you have a separate table for each hash function

EDIT2: In the limit, if the number of hash functions equals the number of bits, then we can see that inserting one element would set all bits in the case where we use separate tables, but only 50% of bits if they use one big shared table.

So the false positive rate is higher if they use separate tables.

Saving any nonzero amount of lives for any unbounded cost is not necessarily a good trade, if there are ways to save more lives for the same cost, or the same number of lives for a lesser cost.

They won't see it that way, but also programmers don't see ourselves as having handed over our power to AI, and yet...

jstanley··on Stolen Buttons
Is it just me or are these almost all terrible?

Almost all of them are animated, move when hovered, move when clicked, or sometimes all three. Just awful. LLMs keep making buttons like this and I keep telling them not to.
