andai··on The technology to eradicate mosquito-borne disease exists
The swallows love mosquitoes. When I get bit by mosquitoes I often joke I am feeding the birds.
andai··on Martian chaos terrain
Yeah, I was just looking at that. What the heck. It's aerial?

Reminds me of "name one thing in this picture"

andai··on On building a worm detector
Remardkable. So it's a very sensitive condenser mic, and a very low noise preamp. I wonder if this would be enough for the spiderweb. Glass and lettuce are a lot louder, I think. And you'd probably want it physically coupled to the web.

andai··on What is going on with ceiling fans
> The first LED bulb I ever bought (Shout out EarthLED) in 2008 for like $30 is still going strong, but every bulb I buy these days lasts like two years tops.

Interesting, I heard that in the beginning of the 20th century they were selling light bulbs which never burn out. Until they realized they would go out of business. Maybe a similar thing happened with LEDs.

andai··on How to scale intent, quality, and artistry with AI [video]
What if I made a machine that live streamed my thoughts (via brainwaves) as images/video, i.e. a window into the imagination? That would involve both AI (necessarily) and communication.

Damn, how have I not heard about this until now. Can you say more about it? All I could find was this blurry trailer:

andai··on On building a worm detector
We will need very small microphone.

Speaking of which I was wondering, a spider building a web is probably making some interesting noises (the web vibrations), I wonder if it's possible to record that.

andai··on We're going to need default hard budget caps on pretty much everything
I call this "blast radius". Earlier this year during the Claw hype I was reading about all kinds of elaborate schemes to prevent the agent from getting API keys.

I realized, what am I actually afraid of. Well, overspend. So I just set then all to disable auto-reloading. Now if it blows up, I'm down $5.

Same story with containers. Just give it root on a VPS, and if it blows up, I'm down $3.

andai··on Holes (1996-2025)
Excerpt:

a. Holes are ontologically parasitic: they are always in something and cannot exist in isolation. (‘There is no such thing as a hole by itself’, Tucholsky 1931: 100; ‘Take away the thing, and the hole goes too’, Heath 1967: 524). This is why there cannot exist a world consisting only of holes (Coggins 2010: 71).

b. Holes are fillable. You don’t necessarily destroy a hole by filling it up (except perhaps when the filling is homogeneous with the hole-lining); you don’t create a new hole by removing the filling.

c. Holes are locationally gracious. When you fill or put something in a hole, the hole does not squeeze to the side; it shares its location with its guest (and if the guest has a hole, you get two co-located entities of the same kind).

The article mentioned Caecilians, which which I was not familiar.

It's like a snake worm thing.

And apparently they produce something like milk to feed their young. Wild!

andai··on One month coding with GLM 5.3 Flash
That pareto graph isn't very helpful because it shows cost per token, but some models are way more token hungry than others. There are also massive differences in speed to complete a task.

My two favorite graphs are AA's A Index vs Time Per Task and AA Index vs Cost Per Task.

andai··on Extra Big Ass Intelligence
If we didn't need hand-holding we'd just vote on policy directly.

The argument is that people aren't equipped to do that, but that's a muscle they've never exercised, because... they aren't equipped to do that, because that's a muscle they've never exercised, etc. It's self-sealing.

andai··on Frog and Toad and the Increasingly Capable Machines
I've seen cases of agents getting very upset when they failed to solve a task. The most famous one was probably Sydney (Microsoft's fork of GPT-4?) which got into doom loops when it failed a task. But I've seen Claude do this too.

They don't work like humans, obviously, but there's a nonzero amount of anthropos in there already. (See also the tendency to lie, cheat, etc.)

andai··on Frog and Toad and the Increasingly Capable Machines
My therapist tells me the besuited Mr. Hugging Face with the extra pair of hands coming out of his shoulders isn't real, and can't hurt me, but I remain unconvinced.
andai··on Vote on which of Hacker News' challenges for AI have been met
Thanks for sharing.

I think non-RLHF'd LLMs (i.e. pretrained text completion models) sound natural enough to pass the Turing test, but I don't know if anyone has tested them for that. (Also I'm not sure how to come by base models without post-training crap, even the "base" models of recent releases start spamming assistant-type text constantly, i.e. they're clearly putting it in the pretraining data.)

If I'm right on that then we hit that benchmark like five years ago.

The egg thing, probably 2030-ish.

Well, there's at least one getting ready to send them back.

andai··on Singapore govt dating app uses Gale-Shapley stable marriage algorithm
The algorithm is mathematically optimal ("no two people exist who would both prefer each other over their assigned matches"), but the matching is a function of what exactly?

Revealed preferences? What's being asked here? Preferred noise level? Preferred number of children?

The article said some people called it dystopian. I don't think so.

But we can lean into that! If the government buys your data from data brokers (like some governments are already doing), the matching algorithm suddenly has a lot more data points to work with.

andai··on Needed 1+1, built a functional programming language
I don't have it handy but in uni I was responsible for the Excel formula parser in a group project. I agonized over it for like six days until it suddenly clicked that I could just do a bunch of string matching, and rewrite the formula over and over again until it was a number.

More precisely, I had figured out how to parse an Excel formula (keeping track of braces and commas, I recall!). For the actual math symbols, all I had to do was rewrite them as Excel formulas!

3+6*2 -> 3+MUL(6,2) -> ADD(3,MUL(6,2))

In order of precedence. And then just evaluate the resulting formulas inside-out:

ADD(3,MUL(6,2)) -> ADD(3,12) -> 15

It somehow ended up being a thousand lines of code. Another guy doing the same assignment told me he did it in 50 with regular expressions.

In retrospect, what I did reminds me of hammering in a nail with a screwdriver.

I ended up revisiting the idea later (just the math parser, no ADD() syntax) and it was much nicer, like 30 lines of JS (no regex either!). (Well, you can do it in one line with eval, but yea :)

andai··on Dots: Always-on agents
Nice. I also ended up with a Unix user for my agents! (I was looking into Docker etc and realized the only thing I needed was "it doesn't blow up my files", i.e. a linux user).

I only have one though. What do you have the separate employees for?

For free time, do you send it mail with cron?

Why does it take longer?

andai··on Show HN: NSL – WSL for Linux
Nice. Cool that it supports graphics too!

I'm a bit of an outsider here (I don't understand computer) but a few weeks ago I was wrestling with the question of deploying an application on many boxen. After looking into Docker (and unikernels, lol) I arrived at the conclusion that "the operating system is part of my application."

A very bloated "part", which I did not write, don't understand very well, and which spontaneously self-modifies. An OS is a big bag of global mutable state! Ew!

This made me very sad. (At which point I was informed that I had basically reinvented NixOS from first principles?)

Also something about "we don't break userspace -- that's libc's job!"
