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:
If something is only available via `cargo install`, is there an easy way to nixify that?

2024-08-16 06:56:56

If you're just starting with #nix, and you read about the basics of the Nix language:
https://nix.dev/tutorials/nix-language.html
but you're having trouble deciphering other people's configs, these two pages will put you on the path:
https://wiki.nixos.org/wiki/NixOS_modules
https://vtimofeenko.com/posts/practical-nix-flake-anatomy-a-guided-tour-of-flake.nix/
A lot of my initial confusion came from not realizing that modules, like flakes, follow a specific template, and aren't just any old derivation.

@npub1wjy…9crp FWIW I have keybindings for both, but it does require remembering to use the buffer binding when only one buffer remains (or not using it at all, and just opening a new buffer on top).

I’m continually amazed by the things that I can do trivially with jj that would have taken me hours of googling with git. I just realized a commit that was deep in the stack had changes I didn’t want to push, so I rebased it into its own branch and pushed the rest. It feels completely routine to do these things -almost without thinking. Pure joy.

There’s no way to sugar coat this: #nix has some of the worst error messages I've ever seen. I'm making a sincere effort to migrate, but there's no way I could possibly evangelize this technology in its current state. I mean, this thing looked me dead in the eye and told me there was an error calling `anonymous lambda` in `unknown file`. That is so ice cold I had to get a sweater.

@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:

also violates the orphan rule…

2024-07-30 01:48:25

@npub1g20…eqrr Ack - no it won’t compile. It looks like we’re writing separate impls for Option types.

@npub1nqq…4e9d std doesn’t implement it for the same reason, I think:
https://fosstodon.org/@dpom/112872643100899617

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 feel like #GitHub should ask about CI when you fork a repo, rather than enabling Actions by default. If you fork a repo like VS Code, it runs (failing) CI *every hour* until you disable it in settings. The VS Code repo alone has 28k+ forks. How much compute are we wasting across the whole site?

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. Is there a pattern in Rust that allows some sort of "read-only public” visibility?

For anyone writing Leptos apps with Neovim + rustaceanvim, this new method of configuring `leptosfmt` (version-specific `rustfmt.toml` + `leptosfmt.toml` + `rust-analyzer.toml`) finally provides a working solution for formatting the `view!` macro:

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.

Somewhere along the line, some kind soul on the internet taught me:

If you hate git submodules, don’t want to think about them, don’t recall if you already initialized them, and just want your repo to have the latest changes, this is the command for you.

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.

A pattern that I see with talented educators is that they model precise language to others without pedantically teaching it.
They say "I think what you're asking is [precise rewording of imprecise question], and the answer to that is…"
The person who asked the question just absorbs the correct terminology, and starts using it to ask better questions
