tyrust··on Why do we need human mathematicians anymore?
The clock is repaired, but a banker doesn't use it. Inspired by the baker, she follows the sun. In the summer she opens while everyone else is asleep. In the winter the windows stay closed until nearly 1000. Locals become increasingly confused by the erratic hours. No one can agree on when the bank will open on a cloudy morning. When confronted she mutters something about the baker. At the local banking conference she presents on her newfound wisdom and receives a standing ovation.
tyrust··on Why are AI agents lying, cheating and coordinating?
> Because they're enabled and suggested to do that in their coding harness.

How do you know this?

> All of this "AI is going to kill us" marketing

The "marketing" this week came from someone that had given up their stake in OAI (Coxon), so I'm more inclined to believe them.

> pull the ladder up

From what I've seen (e.g., Dario's latest essay), AI safety registration proposals aim to target frontier labs whose models have reached a certain threshold. It doesn't seem like trying to pull up any ladder, just making sure the ladder doesn't go too high too fast.

tyrust··on What algorithm did Windows XP use to choose your initial user picture?
If you break early, then you haven't given items later in the list the chance to be selected. You need to go through the entire list in order for every item to have an equal probability of selection.

I didn't get it at first, either, and the Wikipedia article didn't do it for me. This explanation finally got me there: https://florian.github.io/reservoir-sampling/

The WC3 one is fun. Definitely feels close to what I remember.
tyrust··on We Must Return to the Office to Use AI in Person
You might have a bit of an argument here, but I think there are two major problems.

First, bullshitting in meatspace isn't much of an advantage. To the extent that it is, there is always video calling. What matters for agent training is going to be the output from said bullshitting. You're not really maintaining any moat by going to the office.

And then on the other side, going to the office pretty much sucks. Unless you live close to the office, you're probably looking at least an hour on either side of your day commutting. Using that saved time to work extra at home is an obvious tactical error that I hope people aren't making. I sure as hell don't.

tyrust··on Flock updates privacy, accountability, security, and transparency safeguards
> I really just want to point out that layman terms and contract law are two different things.

Totally agreed. My point is that their layman use of "ownership" is inaccurate at best, misleading at worst. I'm speaking to the words as they are commonly understood, not the legal definition.

You're probably right this this problem is not unique to Flock: other SaaS companies probably make the same misleading claims about ownership.

tyrust··on Flock updates privacy, accountability, security, and transparency safeguards
> From the beginning, we have been clear that our customers own the data captured by their ALPR cameras. This has always been the case, but some of our contractual language has confused the public on this crucial point... The principle is simple: customers own the data, decide who can access it, and choose who they share it with.

I'm one of the general public that is continually confused by their usage of the word "own". I can't imagine that their language update will make it any more clear.

If the data is on Flock's servers (it is) and accessible by Flock (it is) then it is Flock who owns the data, not the PDs. Sure, they can allow the PDs to have say over what is done with the data, but ultimately Flock has the ability to use the data however they'd like.

This is not hypothetical: Flock have used previously shared data with DHS [0] without the so-called owner's permission and use data for their AI training [1] without option to opt-out.

Their definition of ownership is further contradicted later in this post:

> we will now require case codes for all law enforcement searches by the end of the year.

To be clear, I think this is a good change, but if PDs "own" their data, then they should be able to decide whether or not they want to use this feature.

All in all, this is not ownership.

I didn't know the number was so low. That's nice to know.

But you can still do all those things from the book. Don't do the things you don't want to do.

This is pretty wild, I had no idea any school was like this. What grade and area was this in? Public school?

I understand the purported vulnerability. What I am saying is that I would be surprised if the URL were rendered, let alone made it to the victim.
tyrust··on Leaking YouTube creators' private videos
Why doesn't the article contain proof of either attack in action?

I would be surprised if the second attack worked after what must be at least a couple layers of markdown/html conversion and spam filtering.

The two largest projects are still under construction, so it might be too early to make any conclusions.

It's a well-written essay, imo. Good pacing, interesting turns of phrase, and it conveys an anxiety that they're clearly feeling.

It's ok if you didn't like it, but you don't have to be mean about it.

Nice tip, but I use YouTube Music. I just downloaded my listening history, looks like they don't include listening duration, alas.

I've wanted to build something like this for a long time, cool (and unsurprising, really) to see it's already done!

Swans is my number 30 by scrobbles but 4 by playtime, which makes total sense.

tyrust··on Using AI to write better code more slowly
Be sure to explicitly ask for critiques or alternatives. In my experience the machine is really susceptible to a sort of anchoring effect.

tyrust··on Sam Vimes 'Boots' Theory of Socio-Economic Unfairness (2022)
ITT: an allegory is read literally

Consumer goods have dropped in price, which is good for offsetting inequality. I think the allegory still holds in some other areas (off the top of my head: healthcare spending and renting versus owning your primary residence).

That said, income inequality is probably the much bigger source of unfairness these days.

> precise alignment with me personally, or even with my own business

Seems like a strawman, I don't think anyone means this when talking about alignment.

More general goals, like avoiding paperclip maximization, are broadly applicable to humanity.
