Incredibly exciting to get official confirmation that Germany's health service (@gematik1@twitter.com) has standardised on Matrix for secure decentralised communications, targeting all 150,000 healthcare organisations in Germany(!!!) 🤯 Read all about it at https://matrix.org/blog/2021/07/21/germanys-national-healthcare-system-adopts-matrix 💉🇩🇪🚀

"npm audit: Broken by Design" by Dan Abramov https://overreacted.io/npm-audit-broken-by-design/

I'm so glad someone finally said this. The current situation is a huge mess.

@jamesvasile In both cases, let acts as a pattern matching operator, although in a bit roundabout way. The key concept is pattern refutability.

Basically, if you’re writing let <identifier> = <expr>, <identifier> acts as the (trivial) pattern that bind the entire rhs to <identifier>. You could also have, say let Some(x) = <expr>, but (outside of an if or a while condition) that would only compile if <expr> is always a Some value. Otherwise the compiler could refute the pattern. So there are two, closely related meanings of let, I guess: as a statement, the pattern must not be refuted at compile time, while in a condition, refutation at runtime causes the conditional to not execute.

This is useful when you want to deconstruct a struct (i.e., product type), because such patterns are never refutable. Example from the Structures chapter of Rust by Example:

struct Point { x: f32, y: f32, } let Point { x: top_edge, y: left_edge } = point;

will assign point.x to top_edge and point.y to left_edge.

This is also very similar to how the pattern matching operator works in Elixir (although Elixir has no let keyword for it and the = operator is always a pattern match, because Elixir has no mutable variables). There, a failed match outside a condition throws a MatchError, since Elixir has no static type checking to validate the pattern at compile time.

one thing i like about fedi is that it’s more like the “old internet” in that you actively have to seek out people instead of being constantly bombarded with suggestions based on what the company that runs the service “knows” about you. it’s a very different process of getting to know people.

most of the mainstream internet is now based on adtech suggestions, and i’m not sure i like the consequences.

like, there’s this growing expectation of getting exactly what you want, and growing distaste for anything else. people seem to have stronger tendencies to just discard anything that isn’t perfectly to their liking, expecting something better to just come their way eventually. this even includes people, with the online dating industry being an example of where things are particularly horrible. the problem of “choice” is being offloaded to bayesian belief networks that can’t make human decisions.

that feeling of jealousy when you realize other people saw the moon

Awesome article on handling/boxing errors in #Rust: https://fasterthanli.me/articles/whats-in-the-box

Returning Results with different types of possible errors always catches me out, and I never really know the best way to deal with those situations

. @bugaevc helped me explore more efficient ways of writing a #rust function that splits a string on a given character. There was a pretty clear winner... unless you've got an idea for an approach we didn't think of.

Being vaccinated does NOT mean it's okay to ask neural nets to participate in meme formats about pandemics that didn't exist when their training data cut off in Oct 2019. You will get memes that make no sense. Be smart.

Well, raspbian has officially become bloatware. Good reason to try Debian for RPi :)
