There are a few gnarly things about Nix, even for someone who’s familiar with Haskell (the most similar language to Nix that’s even close to mainstream).

• Dynamic typing (you mention this briefly). Some people like the extra flexibility that dynamic typing gives, but there’s a tradeoff: more errors. The thing is, due to NixOS’s complicated structure, the traceback for an evaluation error might not give you any information about where the cause is (indeed, the traceback might not include a single line of your own code!). This makes errors unusually costly in NixOS specifically, so any language feature that causes more runtime errors automatically has a worse impact than it would in a more “normal” language.
• The “standard library” (builtins) is extremely sparse. You basically have to depend on at least nixpkgs-lib if you want to get any real work done.
• No real data abstraction mechanisms. No ADTs, no nominal types. The only composite types are attrsets and lists. The usual way to encode a custom type is as an attrset with a _type field or some such.
• While we’re at it, very limited pattern-matching.
• Clunky list literal syntax: no commas between list elements. I can’t tell you the number of times I’ve forgotten to surround list elements in parentheses.
• Can anyone remember the rules for escaping ${ or ''? I have to look them up every time.

Do you have support for smooth full-screen Flash video yet?

I don’t remember if that ever got fixed. Even if it did, Flash was already on its way out by that point.

Vance said this well before he became the VP.

Don’t treat Vance like he’s harmless. Vance is dangerous. Unlike Trump, he has something of a coherent vision, and he believes in things beyond himself. He’ll be willing to violate the rule of law for the sake of ideals.

Vance has an old school polotician side. If left to himself, he wouldn’t go against the courts for example.

Don’t be so sure about that.

“I think that what Trump should, like, if I was giving him one piece of advice, [is] fire every single mid-level bureaucrat, every civil servant in the administrative state,” he said in 2021 on a podcast. “Replace them with our people. And when the courts — because you will get taken to court — and when the courts stop you, stand before the country like Andrew Jackson did and say, ‘The chief justice has made his ruling. Now let him enforce it.’”

Now, Vance doesn’t have the iron grip on 33% of the country that Trump has, so it’s possible that he’d have to be more cautious. But he’s definitely not against ignoring the courts in principle.
