Related to what you said here, I was surprised there wasn't a comparison with Vine Copulas in the paper or thread! But this is pretty far outside of my realm of expertise, so maybe it shouldn't be surprising.

Efficiently? Maybe. Providing the same type trust and guarantees? Probably not. A public, append-only Merkle tree just has a lot of interesting properties and I think there are spaces where they are useful.

As someone who has operated bug bounty programs, understanding what processes might have prevented things from going off the rails _in spite of_ internal actors with different motivations is very helpful to me. Placing all of the blame on an individual removes the opportunity to improve things.

This looks fantastic! I'm working on a desktop app and I've been struggling with the extensibility story in the back of my mind for a couple of weeks now.

Thanks for building this!

edit: For what it's worth, the use case and value of something like this was immediately apparent to me.

This made me chuckle, because I am at this very moment trying to apply the "tagless final style" described here[0] to a custom GUI in a personal-for-fun-and-learning ocaml project : )

For me, I use the simple stuff (Semigroup, Monoid, Monads, Functors, ..) the most. Often times I'll be reasoning about a problem I'm working on in Haskell and realize it is a monad and I can reuse all of the existing monadic control structures. It is also helpful the other way, where you start working with someone else's code and seeing that it is a e.g. Monad immediately tells you so much concrete info about the structure, where in a less structured language you might need to reed through a bunch of docs to understand how to manipulate some objects. The "killer app" is all of that extra structure shared throughout all of the codebases.

I would imagine in the current climate the properties are operating at a profit, don't you?

What about incitement to violence?

Right? Also these companies probably hired a lot of folks during the pandemic, and also relaxed their performance criteria while everyone was adjusting to remote work... So this just sounds like some folks are being caught off guard by the fact that yes, there are real performance expectations and you might not be meeting them.

Why would a crime (especially one external to the university) be better handled by the university than the legal apparatus?

Agreed. If you're an individual who wants to work this hard, hopefully you can find a team of like-minded folks who will work hard with you and make sure that it is structured in a way that you all reap the benefits.

Flask is a multi-threaded server, so while only one thread can execute Python code at a time (due to the GIL), you still get concurrency with respect to IO. Not to say that e.g. FastAPI won't get you more RPS, but it may or may not be as dramatic as you would expect.

I definitely had some uncanny valley vibes watching it, but I think it might be a combination of the camera's perspective (distorting distances away from center) and the footage being sped up/slowed down.

I'd think it is something like a ratio of bitrate to entropy. How quickly is information being processed relative to how quickly it is being lost?

I think it is safe to assume that most/all (large) modern countries have paramilitary forces that are used to carefully tip the scales toward outcomes that are in their best interest in situations like these.

Uniformity, presumably

Presumably there would be a similar page in the Gitlab Handbook if they had findings

I'm not sure how meaningful it is to separate politics from religion at the the level of the individual person. Those two things are strongly interconnected and together constitute a large chunk of an individual's personal beliefs.

In the physical world there are folks who design bridges, dams, buildings, telescopes, furniture, and a million other things. All of those have unique requirements and skill sets. In software, we also make a huge number of categorically different systems each with its own skill set, but we call all of it 'software engineering.'

There are folks who are great at their job (called "software engineering") and their work never invokes their knowledge of algorithms. There are also folks who spend day in and day out tuning and designing new systems and deep knowledge of algorithms is essential (we also call this "software engineering").

> does any sort of protest outside the capitol = "coup attempt"?

The rally was organized under the headline "Stop the Steal." It was very explicitly the intent to prevent the peaceful transition of power.

> It insists on having a chain of updates from a single user, which feels unnecessary to me and something that adds bloat and rigidity to the thing — each server/user needs to store all the chain of posts to be sure the new one is valid. Why? (Maybe they have a good reason);

I assume this is so a relay can't manipulate your messaging by picking and choosing which messages to forward; they'd have to forward messages [0-N].

Edit:

Signed hash rather than a mac - might be vulnerable to an extension attack

Is that not the very purpose of legislation? Laws are not written in stone

I think the severity of this would very much depend on the permissions that would have to be granted to the extension in order for it to happen.

I don't have an Oculus or even Facebook, but I remember a decade ago that my older relatives were hostile toward the idea of Facebook and moving aspects of their daily lives online. That all changed very quickly and has been very profitable for FB. I don't know if it will be brought about (in part) by Facebook, or if it will even happen anytime soon, but something akin to a "metaverse" seems almost probable to me at this point

Oof, that certainly doesn't seem to be a good faith argument on the article's part.

I agree that it doesn't improve things at the service interface level. What I have found is that I often have several internal libraries, and a monorepo ensures that I know if a change to my library breaks another service because they're all in one build. Keeping things consistent across services is very useful in my experience.
