I'm not sure if I have the right mental model for a "skill". It's basically a context-management tool? Like a skill is a brief description of something, and if the model decides it wants the skill based on that description, then it pulls in the rest of whatever amorphous stuff the skill has, scripts, documents, what have you. Is this the right way to think about it?

At first this sounds cool but I feel like it falls apart with a basic example.
Let's say you're running a simple e-commerce site. You have some microservices, like, a payments microservice, a push notifications microservice, and a logging microservice.
So what are the dependencies. You might want to send a push notification to a seller when they get a new payment, or if there's a dispute or something. You might want to log that too. And you might want to log whenever any chargeback occurs.
Okay, but now it is no longer a "polytree". You have a "triangle" of dependencies. Payment -> Push, Push -> Logs, Payment -> Logs.
These all just seem really basic, natural examples though. I don't even like microservices, but they make sense when you're essentially just wrapping an external API like push notifications or payments, or a single-purpose datastore like you often have for logging. Is it really a problem if a whole bunch of things depend on your logging microservice? That seems fine to me.
Can I hop in here and ask: As someone who hasn't done any systems programming in a decade, what would be more interesting to learn on the side, Zig or Rust? I've been in the Python world and seeing tools like uv and ruff, makes me biased towards Rust but Zig seems to be attracting a lot of hype recently?
Edit: Thank you all for your responses!
I feel like Zig is closer to "better C" and Rust is closer to "better C++". So I'd pick based on whether you are more in a C mood or a C++ mood.
But how is another company that is also VC backed and losing money providing stability for Bun?
How long before we hear about “Our Amazing Journey”?
On the other hand, I would rather see someone like Bun have a successful exit where the founders seem to have started out with a passion project, got funding, built something out they were excited about and then exit than yet another AI company by non technical founders who were built with the sole purpose of getting funding and then exit.
The real risk is not that Anthropic will run out of money, but that they will change their strategy to something that isn't Bun-based, and supporting Bun won't make sense for them any more.
A similar problem that I like.
A "lattice point" on the plane is a point where both coordinates are integers, like (3, 4) or (-2, -1). Prove that for any five lattice points, there will be two of them that if you connect them with a line segment, there's another lattice point between them on that line.
IMHO Python killed both Perl and Ruby. While Ruby is more alive than Perl it's nowhere near as popular as Python.
I like Perl and used it professionally for year and vaguely remember probably around 2010x relatively massive Python evangelism (lots of articles, conferences, lots of messages from Python adepts on forums e.t.c). One of talking points (no longer needed nowadays) was that Python is backed (sponsored) by Google so Python will be successful and you should not worry about it's future and also if you will choose Python you will be successful (as Google is).
I think Ruby has declined because Rails was its selling point, but Rails was optimized for the world of HTML templates. Once you're writing JavaScript-heavy frontends and mobile apps, Rails isn't giving you much that you can't get from Python or server-side JS.

They haven't built their own editor, they haven't built their own models; what have they actually built?
Something people want, apparently!
I was in SF a few weekend ago and rode both Waymo and normal Lyft style taxi cars. the Waymo was a better experience in every single way. One of the Lyfts i was in drove on the shoulder for a while like it was a lane. The Waymos were just smooth consistent driving. No aggressive driving to get you dumped off so they can get to the next fair.
I was riding in a Waymo recently and it suddenly braked for no reason at an intersection where it didn't have a stop sign. I was like, what the heck, this Waymo is broken, it didn't see that the stop sign is only two way. Then a little kid on a bike riding along the sidewalk at an angle where I hadn't seen them just barely braked to a halt before riding into the street in front of the Waymo.
These things must be saving lives, it's obvious. When my kids are riding their bikes around I want the other cars to be Waymos, not human drivers.

I don't think this counts as property damage or vandalism because nothing is damaged or vandalized.
Part of putting shit in public is that it now has to interact with the public. If you want your stuff pristine, I would think you should not put it in public.
Maybe the law disagrees with me here, and it probably does because this country bends over backwards for companies, but that's how I see it.
Obviously it's property damage. How would you like it if someone covered the windshield of your car with glue?

Some guy I once met in a bar told me that he liked to mix a 1:1 solution of elmer's glue and water, put it into a spray bottle, set the nozzle to "stream", then squirt it all over the lens of a traffic camera near his house which he found offensive. His logic was that this made more sense than destroying the camera, because he could do it over and over and over: the company operating it would have to send someone out to clean the lens off each time, which would probably cost them more money than the camera was worth.
It makes sense to me that criminals, like this guy you met in a bar, are opposed to Flock cameras.
