At some point, we have to reckon with the fact that most of the world's infra runs on a kernel developed in an utterly toxic environment. I don't know how far off we are from container runtimes for kernels like Redox, but I can't be the only one excited about that future—we should think about how best to support it.

Wow, IDK how I feel about #nix `with` statements. The way they sorta stack up in the environment, and then you can just use any of them without any explicit clarification which one you're using. And then what? Nix just tries all the possible variations, and tells you if there's a collision? Am I missing an easy way to tell which `with` is in use by any given line of code?

@npub1v0k…3x3r You're right on both counts - you'll need vim.opt.undofile = true, and disabling swap is optional. I was showing my personal bias there, because I find swapfile warnings are a nuisance.

Hello #Nix + #Rust fans:

2024-08-16 06:56:56

If you're just starting with #nix, and you read about the basics of the Nix language:

https://wiki.nixos.org/wiki/NixOS_modules

I’m continually amazed by the things that I can do trivially with jj that would have taken me hours of googling with git.

@npub1g20…eqrr Actually it *does* break all of those potentially, because `T` could represent an `Option` type, like `Option<u32>`. The problem is that I’m contraining my ideas of what T could represent, but the compiler isn’t.

This is worse than I thought. I actually can’t even do this with concrete types:

2024-07-29 23:40:31

Orphan rules prevent me from writing a blanket implementation of `From` for `Option` types, but I don’t really understand why. Since my implementation doesn’t touch the underlying implementation of `From` for `U`, I feel like I should be able to get away with this.

I have these #RustLang newtypes where I want the inner field private because of checks in the `new()` constructor, but then later I wish I could pattern match to get the inner value, and the private field prevents that.

Prettier accepts config files in TOML, which I prefer, but I have a line in my (JS) config that I can’t seem to translate:
`overrides: [{ files: "*.md", options: { tabWidth: 2 } }],`
In JS, overrides is an array of objects, so I assume the TOML equivalent would be an array of tables (`[[overrides]]`), but if each override table is a value, what is the key? In JS the objects in the array are just anonymous. Prettier docs don't give any examples of this pattern in TOML.

It seems like it should be possible for our version control systems to have both Squash and Expand (meaning, lossless squashing). It would allow a collapsed commit history to appear "clean" and yet not lose any history. In some sense, `jj operation log` already permits this (`git reflog` would only work locally), but what I'm envisioning is the ability to simply call `git log --expand <commit>` to see all commits squashed into that commit. Basically, allowing commits to nest.

@npub1crs…ge7y APIT is confusing because it lures the user into thinking that impl Trait can represent a generic in other places, like RPIT, when in fact it can only represent a concrete type.

@npub1t6q…nkcf It does, but APIT accepts multiple types (a true generic), whereas RPIT is a stand-in for only one concrete type. This is what trips people up.

2024-07-02 05:40:30

impl Trait in return position is super useful, but impl Trait in argument position seems like it saves a few keystrokes at the cost of totally confusing every newcomer to #RustLang.
I think there is a big difference between teaching people that impl Trait can only be used in certain places, versus teaching them that impl Trait has different meanings in different places.

I don't really understand what #RustLang's Cell<T> looks like at runtime. Does it still exist? Presumably it depends on T—something like: If T is on the heap, then Cell<T> is a pointer, but if T is Copy then Cell<T> is pretty much erased?

This is such a helpful diagram, showing the layout of common #RustLang pointers/containers in memory. I think this sort of thing should be in The Book. If it strikes you as too advanced for that audience, think about how hard it is for beginners to navigate the constant barrage of `Sized` bounds without this mental model.

IDK how many blog/forum posts I've read about this topic, but this explanation is so crystal clear that several years of accumulated misconceptions just melted away. If you write any sort of documentation, check out the way complexity is acknowledged rather than hidden, and yet the explanation itself is not complex. This is art.

I find it strange that people keep commenting on the number of plugins required to use #Neovim, but IDEs like VS Code don't seem to be held to any standard regarding extensions. Out of curiosity, I just opened VS Code, to see how many extensions I was using when I switched: It was more than 90. Even if you allow for the fact that some of those extensions were installed for one-off tasks/projects, it's still notable that it’s more than twice the number of nvim plugins I use.
