So I guess if telepathy is possible, there should be a Higher Order indication for people who share a link huh?

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.

Couldn't that be more efficiently solved using a public database maintained by a trusted third party? We don't need a blockchain to know who owns shares for example.

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.

So… a federal jury found this guy guilty, but here we have a friend of his who is going to be totally neutral in a reevaluation?

So they set out to describe it as „an accident“ because „blameless post-mortems“ are something people really like?

Also this article falls into the trap of trying to sound smart by using, sorry, „by effecting the usage of“ big fancy words. I’ve read Supreme Court transcripts and judgements, and I can understand them. This is overtaxing my buzzword ingestion.

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.

Same here. I drank the cool aid a few years back, and started using fp-ts in my frontend projects, hoping to use algebraic data types regularly. But today all I use is the Monad. I can't find any motivation to write abstract algebra to build UI widgets.

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 : )

I would be willing to drink the kool-aid if I saw it being used in a practical way. I always feel these posts are filled with category theory jargon without ever explaining why any of the jargon is relevant or useful. I’ve even watched some applied category theory courses online and have yet to feel I’ve gained anything substantive from them.

However, as I started off with, I’m always willing to try something out or see the reason in something. Can anyone give me a practical applied way in which category theory is a benefit to your design rather than just creating higher level jargon to label your current design with?

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.

Because he is in debt to his eyeballs on those rental properties. In 30 years when they are paid off he will be rich, but right now he probably can't make ends meet without that income.

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

The premise of speech is damaging, unless it's slander / libel, is I think the main thing Elon Musk wants to change at Twitter.

Most likely because of the pandemic -- that's what happened at other companies, e.g. Meta
floober · 3 years ago
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.
