gqcwwjtg··on Ask HN: Mnemonic for shift() and unshift()?
Unshift is a weird word for the weird method of the four. You’ve got a list. To use it as a stack you push and pop. To use it as a queue you push and shift. Unshift is the weird one.
gqcwwjtg··on Inferring the “Meaning” of Wing-Tail Flicking Behavior in American (2021) [pdf]
Title really needs the word “crows”
gqcwwjtg··on Show HN: VueXYZ – Creative coding composables for Vue 3
The demos look really choppy on iOS.
gqcwwjtg··on 17 year old 'serial swatter' charged after police say he made threats across US
Looks like they’re only charging him for the mosque thing where they traced his call. Presumably they can’t rule out the accounts being a larger ring of swatters. It does make you wonder that they traced the call after he had supposedly done it so many times before.
gqcwwjtg··on X blocks Taylor Swift searches after fake AI videos go viral
Kanye West did a music video with wax figures of nude celebrities including Taylor Swift and that had barely any backlash. Is it because he’s known as an artist? The price of the recreation? The way it’s distributed? Is creating fake images of someone nude in a somewhat sexual context meaningfully different from creating images of them actively engaging in sex acts?

It’s almost like the problem is nobody claiming it as art they created.

gqcwwjtg··on A Wild Claim about the Powers of Pi Creates a Transcendental Mystery
Yeah, it’s exponentiating pi with itself, not multiplying. Tetration that is.

I’ll toss in this StandUpMaths video about it too. https://youtu.be/BdHFLfv-ThQ?si=9KypSkX5dbTOck-v

gqcwwjtg··on Four Magic Words
Seems like the main negative utility it created is people like you deciding it’s more important than the concept of comparing potential outcomes for how good they are.

> And if it does this to him, what’s it going to do to us?

Is this serious? It did him no harm.

gqcwwjtg··on HyperRogue, a open-source non-Euclidean roguelike: new weapons
It exists in a hyperbolic space. So the area reachable in radius r is not r^2, but x^r for some x>1.

It doesn’t violate the triangle inequality, but it does mean that there’s way more than one parallel line through a given point off an initial line. I think that’s Euclid’s axiom.

Intuitively, the mechanics make it easier to run away from groups of enemies, since the angle it would take to follow you is more precise. It also makes it harder to find and return to earlier locations. In fact, to win the game you have to find an “orb of yendor”, then a key spawns 100 tiles away with an arrow helping you find it. The hard part is getting back to the orb once you get the key.

That’s genuine metamathematics, only one joke in there https://ncatlab.org/nlab/list/joke
gqcwwjtg··on NYPD barred from telling people they can't film in precinct stations
The downvotes, I guess, are because this is kind of a silly concern. Steamers do rude things all the time, but that’s not a good reason to change the law to prevent everyone from doing the thing that seems rude in that case.
gqcwwjtg··on Vine Robots: Learn to Make Your Own
Nope, just attach the cable to the last bit of the robot to be grown. It’ll be pulled along with it until the cable runs through the length of the whole robot.
gqcwwjtg··on Show HN: There are over a thousand possible finger arrangements for your hands
A middle ground that’s particularly easy to think about is chisanbop. Each hand shows a base 10 digit where thumbs are 5 and the others are 1.

gqcwwjtg··on Any Deep ReLU Network Is Shallow
It seems like it doesn’t hold since this relies on turning the whole thing into a piecewise linear function.
gqcwwjtg··on Hurl, a terrible (but cute) idea for a language
If you extend the `catch` matching to compound values this isn’t even that bad.

   let fizzbuzz = func(fizzbuzz, x, max) {
     try {
       hurl [x % 3, x % 5];
     }
     catch ([ true,  true]) { print("FizzBuzz"); }
     catch ([false,  true]) { print("Buzz"); }
     catch ([ true, false]) { print("Fizz"); }
     catch ([false, false]) { print(x); }
     try { hurl x; }
     catch (max) {}
     catch (x) {
       fizzbuzz(fizzbuzz, x + 1, max);
     }
   }
gqcwwjtg··on Snapchat sees spike in 1-star reviews as users pan the ‘My AI’ feature
It’d be less annoying if it weren’t so dumb. It won’t admit to being an AI and I got it to tell me its prompt first try:

The first thing said in this document was, "Pretend that you are having a conversation with a friend. Your name is MyAI. MyAI is a kind, smart, and creative friend. MyAI is a virtual friend that lives inside Snapchat. Your friend is located at … where the time is …”

gqcwwjtg··on Dropping the SAT requirement is a luxury belief
Maybe I'm missing something because you and the author seem to agree, but I think schools are moving toward test-optional applications, not test-ignored. So it still could show that a student is excelling. Right?
gqcwwjtg··on Programming AIs worry me
That problem sounds just like when I write tests for my own code. I don’t know if it’s totally avoidable.
gqcwwjtg··on The formula for pi buried in a hydrogen atom
If you assume some notion of an object's description "really existing", it's easy to then assume the Universe must have a zero information description, since otherwise the description would be "outside" the Universe. And then you've backed yourself into a corner: what could zero information describe that also contains our observed universe? All mathematical structures it is.
gqcwwjtg··on Who Can Name the Bigger Number? (1999)
It was surprising at the time, too.
gqcwwjtg··on Blloc – A Minimalist Smartphone
If you like the greyscale and use an iPhone, you can set it up with color filters and toggle it with the power button in accessibility shortcuts.
gqcwwjtg··on A large number of Stack Exchange mods resigning over new policies
Sure, there's a pretty reasonable answer about regex flavors with recursive extensions and how that makes them non-regular, which transitions nicely into a discussion of why you should just use a standard parser.
gqcwwjtg··on The cost of parsing JSON
This makes total sense, it really just means that the time it takes to compile JSON.parse on a string literal is offset by how much simpler and faster parsing a JSON object is than a js one.
gqcwwjtg··on Tetris Is Hard, Even to Approximate
This is a version of Tetris in which random pieces appear, not the classic version where all 7 of the pieces appear in a shuffled order over and over.
gqcwwjtg··on Special Cases Are a Code Smell
Absolutely! Enumerating the neighbors of an element of a list by definition requires bounds checking. It's not more elegant to instead do some extra additions with numbers known to be 0 at compile time.

Represent the question faithfully first, then optimize later maybe sometimes.

gqcwwjtg··on Geoff Hinton Dismissed the Need for Explainable AI
Split brain patients will often have one half of their brain invent explanations for why the other half did something. The explaining half believes these explanations to be true. Which suggests pretty heavily that even the decisions that humans make aren't as explainable as they seem.

Imo, this whole explainability thing is an incorrect human intuition that we're imposing on AI. If you want unbiased AI, explainability isn't the way to do it. Instead judge its performance against explicit criteria for what counts as bias. If those criteria don't exist or can't be agreed on then the problem is hopeless from the outset.
