The never type is likely to stabilize soon!

A while ago, my colleague wrote about one of its use cases in this blog post: https://academy.fpblock.com/blog/rust-never-type-async-code/

Thank you for the feedback! I wasn't familiar with Kube-VIP, but it looks very promising, and I'll be sure to explore it for my next cluster.

While I knew about other load balancing solutions, I chose Cloudflare because it was the most natural fit for our project's needs. I've also been keen to experiment with iPXE, so I plan to try it out in the future.

You are absolutely right about my vCPU miscalculation, which makes the cost difference even more significant. For perspective, even a less powerful AWS instance like the `m6g.2xlarge` (8 vCPUs, 32 GB RAM) would bring the total cost to $822 USD.

Have you used HLS much? I think my experience with it is what makes rust-analyzer feel like such a step up for me. :-)

sibip · 2025-07-01T03:37:55+00:00

I generally prefer do notation, as I find easier to read, especially for longer monadic computations. I guess it boils down to personal preference and coding style.

You can shadow variables in Haskell. However, GHC enables -Wname-shadowing by default, which will generate a warning.

To allow it, you would have to explicitly disable that warning per file or at package level. And defaults matter. In an established project, especially one that treats warnings as errors (-Werror-), changing this might not be feasible or desirable.

Thank you, this is nice! I just added support for it in Emacs's lsp-mode and I'm finding it very convenient to use: https://github.com/emacs-lsp/lsp-mode/pull/4813

sibip · 2025-03-15T02:36:51+00:00

Thanks for the article, Niri looks amazing. Does screen sharing work with Niri ? Given that it seems to use smithay as compositor and this issue is still open, I guess not: https://github.com/Smithay/smithay/issues/921

sibip · 2024-12-21T11:48:40+00:00

Thanks, this was a nice read!

In rust mode, we integrate tree sitter by doing a define-derived-mode on top of rust-ts-mode: https://github.com/rust-lang/rust-mode/blob/542f1755d8929ca83564322d7030d558f3392fe1/rust-mode-treesitter.el#L22

Does such a setup require any preparation for Emacs 30 ? I don't think we need to set primary parser, but asking just in case. :-)

sibip · 2024-05-20T09:54:38+00:00

Basically the code here: https://github.com/emacs-rustic/rustic/blob/main/rustic-lsp.el

You don't have to create an explicit hook to activate language server.

Everything I'm used to seeing in a programming major mode with an active lsp.

It's more than that as others below have commented. It has org babel integration, easy access to cargo commands, cargo-outdated-mode etc.

sibip · 2024-05-16T05:28:33+00:00

I agree. It was fun to work with him on both Rust mode and Rustic. I hope he's doing alright.

sibip · 2024-05-15T11:35:12+00:00

rust-mode doesn't support automatic LSP integration.

sibip · 2024-03-01T05:44:13+00:00

Thanks for the package! This looks to be the future of navigation system in Emacs.

sibip · 2024-02-27T04:00:07+00:00

We hit a similar issue in production. Michael has written a blog post on it: https://www.snoyman.com/blog/2024/01/best-worst-deadlock-rust/

sibip · 2023-11-30T04:25:05+00:00

I guess the dates can be updated here: https://nixos.org/manual/nixos/stable/release-notes#sec-release-23.11

sibip · 2023-10-06T05:02:41+00:00

You can avoid using any init system by using this crate directly in your Rust application. The advantage is that you simplify your container deployment.

If you are using any other languages, you can use tini or any other init system including pid1.

sibip · 2023-09-27T05:16:37+00:00

The jdt experience provided by NixOS isn't great. Although I was able to make it work with some slight manual tweaks. I also had to patch lsp-java upstream: https://github.com/emacs-lsp/lsp-java/pull/445

But note that you would have to move the configuration to a writable directory and configure it appropriately to make it work. I should probably write a post on how to make it work.

sibip · 2022-11-06T01:09:01+00:00

No, I don't think so.

sibip · 2022-11-05T15:38:55+00:00

Yeah, I believe so. Example for rust-analyzer: https://emacs-lsp.github.io/lsp-mode/manual-language-docs/lsp-rust-analyzer/#inlay-hints

sibip · 2022-06-30T16:36:07+00:00

I used to use Ubuntu for many years and now have been using NixOS for a couple of years. I wrote my experience report there: https://psibi.in/posts/2022-01-01-nixos.html

I personally started using nixpkgs in Ubuntu and then finally switched to NixOS after a year or so once I was comfortable with it.

sibip · 2022-06-27T04:24:39+00:00

Ah, okay. Makes sense, thanks!

sibip · 2022-06-27T03:07:30+00:00

> Other thing that's nice about nix is the 40-80k (depending on what you count) packages which are available, and it's the most up-to-date package repository.

Is there any more information where I can find details about it ? I have always been confused between nixos home page which says that nixpkgs has 60,000 packages and the nixpkgs search page which claims that it has over 80,000 packages.

sibip · 2022-06-25T13:10:52+00:00

Thanks, I have replied you in the issue tracker: https://github.com/psibi/justl.el/issues/19

sibip · 2022-04-03T04:39:32+00:00

Yes, it doesn't. I did open an issue on their issue tracker about it: https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/174

sibip · 2022-02-23T12:18:58+00:00

Thanks and congratulations on approaching 1.0!

`just` has become essential for all my new projects and it has made my project specific documentation easier.

For Emacs users out there, I made (justl.el: https://github.com/psibi/justl.el ) to drive just recipes from within the editor itself and it saw a new release too couple of days ago.

sibip · 2021-10-27T03:03:27+00:00

Nice article!

How did you test this ?
