After a long and winding waiting room… Cats Effect 3.7.0 has finally been tagged! https://github.com/typelevel/cats-effect/releases/tag/v3.7.0 This is a big one because it represents the culmination of all the planning and scheming and hard work to make truly native multithreaded execution functional on Scala Native 0.5.

@matejcerny@witter.cz I believe the technical term for this is “bootstrapping”, a reference to Chuck Norris landing a roundhouse kick squarely in the AST.

@dpiponi Have you read the book? Weir goes to some lengths to create a plausible mcguffin to explain the astrophage’s insane energy storage density. Just trying to gauge if that got lost in movie making.

@dpiponi Genuinely one of the better books I've read in the past few years. The movie annoys me all the more since it spoils many (though not all) of the greatest notes in the book without presenting them in the same comprehensive intellectual and emotional light.

@dpiponi Update: saw the film. Amazingly bad adaptation. Literally all the science is stripped as you said, and it’s effevtively impossible to follow without knowing the book. Which you should read btw because it’s very good. The answer to conservation of energy btw is the astrophage does direct mass energy conversion. So a small amount converts an absurd amount of energy. That’s also why the distinctive IR emission spectrum.

@alexelcu@mastodon.social This is very cool and I started something similar on the cats-effect-direct project. I think the main thing it's missing is the ability to do it on the JVM across arbitrary threads. I know that needs a startup flag to enable but it's the difference between it being game-changing for libraries like CE vs being something that we can't relaly use.

@dpiponi That's pretty annoying tbh. In the book science is definitely a major focus, though less so than in The Martian. Weir's style in general is to be pretty grounded in facts and only cheat once or at most twice in some way that generates the plot. Like in The Martian where the dust storm winds are enough to cause their launch vehicle to tip (the air pressure is too low for that to ever happen), but then everything after that is pretty rigorous. Similar with astrophage energy density here.

@jonafato@mastodon.social @ross@social.rossabaker.com I mean I agree with what you're saying, but maybe I'm missing something, because it feels like this type of tooling is almost trivial to implement yourself if you're willing to inline the locking and add some ignored YAML.
