> You write on your site; I write on mine. That’s a response. I don’t use comments on Wilcox’s site to respond publicly to his pieces, but somehow it’s unfair that he can’t use comments on my site to respond to mine? What kind of sense is that even supposed to make?
How is it hypocritical to hold the view that some places are intended to be open forums for comments from anyone, and others are not?
Also, by not hosting my own comments, all public commentary on my writing is thus out of my control. I don't get to block comments I don't like here, or on Mastodon, or Twitter/X, or Bluesky. I think that's actually for the better.
DF is a blog and was conceived that way. HN is a discussion site. The two forms (blogging and internet discussions) are different. They serve different purposes and require different management styles.
The discussions here do seem to be tamped down in some ways, and as a user, that takes something away from the experience.
Relatedly: in general, I think "hypocritical" is not a big gotcha that ends discussions. Different things serve different purposes.
The site's source code is already updated, but unfortunately the website itself is refreshed per Rustup release, so we might have to wait for a bit longer...
NVIDIA started publishing more of their driver as open-source in 2022, which while not hardware documentation probably helps a lot.
You may be wondering why Red Hat is bothering with this effort then? I assume it’s so that the code can be added to Linux directly as opposed to being out of tree.
> the Gleam aspect of this is inessential, TypeScript is quite good
TypeScript can be quite productive but I find its type system lacking. Specifically the use of structural typing/lack of nominal typing and lack of sum types. I find these extremely useful when writing reliable software, which is why Gleam appeals to me.
Edit: lots of replies showing how TypeScript can be made to do exhaustiveness checking. It's neat and all but it's a lot of gymnastics compared to languages that just have this built in, which again is part of the appeal of Gleam for me.
For the most straightforward nominative pattern matching, I would write a small match function:
type A = { kind: "kindA", a: "dataA" }
type B = { kind: "kindB", b: "dataB" }
type Sum = A | B
const match = <
const V extends { kind: string },
const C extends { [ kind in V[ "kind" ] ]: ( value: V & { kind: kind } ) => unknown }
>( value: V, cases: C ) => cases[ value.kind as V[ "kind" ] ]( value ) as ReturnType<C[ V[ "kind" ] ]>
// You check the type of result, change the type of value to A or B, make the cases non-exhaustive...
const howToUse = ( value: Sum ) => {
const result = match( value, {
kindA: _ => _.a,
kindB: _ => _.b
} )
}
I ran into this exact issue when I was working on a piece of typescript that interoperates with a rust server, here's how I was able to do exhaustiveness checking (the errors aren't the prettiest, but it works): https://github.com/wwtos/mjuo/blob/main/vpo-frontend/src/lib...
Yeah, that can be annoying. Until pattern matching makes it into JS, the main way people deal with this is to use a library. For example, ts-pattern lets you stick `.exhaustive()` at the end of a match call and I believe you get the error at typechecking time, not runtime.
The function call will fail at compile time if yourUnion is anything more than never, which you can use in your else case of if statements that narrow the discriminated union.
I think it would be good to include some examples in the README to show off what it can do. Also how to invoke it: can it find SQL embedded in other source file or does it need to be pointed at .sql files.
Not that I'm aware. There's some discussion about it in this post from 2010:
