Nix on macOS Catalina

I'm writing this gist for my own records but it might help someone else too.

Installing Nix

Support for Catalina has improved a lot since the update was first rolled out.

Note: See the NixOS manual for discussion of the --darwin-use-unencrypted-nix-store-volume option.

  parseCRLF = (ch ?\r Unipar.>> ch ?\n)

• Pgtk is not enabled by default, for that you can either override the derivation or use emacsPgtk from the nix-community emacs overlay if you don't want to build it yourself

At the beginning of 2030, I found this essay in my archives. From what I know today, I think it was very insightful at the moment of writing. And I feel it should be published because it can teach us, Rust developers, how to prevent that sad story from happening again.

What killed Haskell, could kill Rust, too

What killed Haskell, could kill Rust, too. Why would I even mention Haskell in this context? Well, Haskell and Rust are deeply related. Not because Rust is Haskell without HKTs. (Some of you know what that means, and the rest of you will wonder for a very long time). Much of the style of Rust is similar in many ways to the style of Haskell. In some sense Rust is a reincarnation of Haskell, with a little bit of C-ish like syntax, a very small amount.

Is Haskell dead?
