just don't use emacs inside a terminal emulator...

This makes me think it would be interesting to have a programming language where we can write multiple statements on 1 line separated by semicolons and then in that particular case the execution order is unconstrained, but when separated by lines the execution order is constrained to be top down. Or something similar like we could end statements with colons to make the execution order unconstrained.

This is the best explanation of the difference between flakes and traditional NixOS I've found. Thank you so much Silvan for making it so much more clear.

I was surprised to find the order of the overrideAttrs matter! When I tried building at 12:26, I was getting strange error because I put "custom" first. The error was happening at the cat command, which tries to cat out the filename in out. It says it does not exist. I wonder if anyone knows why the output matters? Thank you in advance!

Could you sort the Nix Hour playlist in ascending order? Thank you for for the lectures :D

NixOS is truly amazing and I want to use NixOS but I have a metered internet connection with limited data every day and you can't see the size of packages in NixOS. If NixOS had the feature of viewing size of packages before downloading them like other distros and if somehow they can also add the feature of pausing and resuming for large downloads it could become my go to distro for life.

Mind = blown

Wtf was far ending... Highly disappointed in this channel.

49:54 watching you almost adding regex to that if statement whilst overriding callPackage was peak comedy. And then immediately jumping into special-case recursive lib overlays. 12/10 content. so glad these videos are free lmao

This is perfect. I'm currently having to package Ansible Galaxy Collections but they don't provide a lock file or anything so I have to do manual updates. Putting the information into a file to read from makes it much more usable for my colleagues that don't know Nix that well and maybe even lets me combine it with renovate bot.

Awesome presentation & presentor explanations

(audio starts working at 3:16)

Damn i stumbled on a goldmine. Thanks for the tutorials ❤

THANK YOU for providing Nix/NixOS knowledge for the community every week!!!

It would have been good, if the interesting presentation were recorded locally for better audio quality. Thanks Solène!

For the repack issue, having a clearly specified, fully deterministic subset of tar/nar and gzip would be useful.

Thanks so much for putting this together. So many things just clicked for me (especially with derivations) watching this

Thanks for this great series! Your audio recording has very prominent sibilant consonants (the sharp sounds created by e.g. „s“, „sch“, „j“, etc.), which are especially noticeable over headphones. Piping your microphone signal through a de-esser to eliminate the sharp sounds might offer some improvements with relatively low effort. Even better: consider borrowing or buying a decent microphone and learn how to EQ voice signals. There are a host of plugins for OBS, etc. that provide EQ functionality.

Cool insight - nix channels being the tool for delivery purpose, not a reference purpose - now just being missapplied

Some remarks: - 2:00 the extra newlines when pasting into vim was due to vim formatting the pasted lines, which can be (temporarly disabled) in various ways, e.g. `:set paste` - The terminal glitching at 21:40 is because of the columns configured in the serial tty, you can increase that with `stty columns 200; stty rows 70;` and it's probably good to `export TERM=<your-host-terminal-emulator>` (might need `environment.enableAllTerminfo = true`)

Thank you for this discussion! I have a favor to ask... Can you create a blog with a super fast example of how to make configuration.nix as pure as is reasonable. I am asking because I maintain applications hosting servers. I need to be able to fire up a new server and have it (the new server) resemble the existing server (same jvm, db, tools, etc...). Since I am not performing builds, I believe I only need to ensure the nixpkgs is pulling from a specific tarball to ensure I am getting the same app definitions. Thanks again for your time and consideration. I am happy to support/sponsor your efforts. Chuck

Looking forward to more videos! These were all really interesting!

Thank you for linking Nix* docs with your tutorial, and for explainingto those of use who are just learning about Nix* universe.

Nice

Seems like this episode got cut off short? Unless 38:47 was the actual end... In which case I don't think this topic has been fully covered. `rustPlatform.buildRustPackage` for hello-world is only scratching the surface.. What I'd like to see is the process of making a nix devshell/build setup for some sophisticated Rust project that depends on significant libraries (like libGL or something) and has some non-trivial build setup, actually pushing the builtin lang2nix integrations (like buildRustPackage). Or, even better, that same process but for a language that doesn't have a builtin `buildLangPackage` integration, and expects you to use its own tooling. Are you forced into a custom buildPhase script, and if so what would your process for writing it be? Thanks for making these videos, always learning something new.

Great practice today sir, thank you very much sir 👍👍👍 1:01:44

Posting your playlist to the Nix OS Stacker News territory , come for an AMA if you have time. If not keep up the great work!

Good day sir and nice to meet you sir. 2:07

Amazing lecture! I wonder what can we do today (latest stable released is GHC 9.8.2 as I'm writing this) to mitigate some of these problems by default? StrictData + use our own strict data types (or some from `strict` package on hackage)?

Do y'all intend to continue this series? I've really loved it.

That ad hoc typeclass is truly disgusting! (Though of course effective) I would have added a parameter that's a function that turns a word into a monoidal value, List.singleton for the list case and const (Sum 1) for the "count number of words" case.

It seems unfortunate that Set's type parameters is inferred as role representational in the first place. Modulo breaking change, wouldn't it be better for GHC to infer all type parameters as nominal for a type with private constructors, unless explicitly annotated otherwise? Or something to that effect?

You guys stream on twitch as well?

hilarious, you can have a fully reproducible system, if you can ever get it produced!

First 5 minutes is why i cant fking stand nix.

I finally made my first contribution for nixpkgs this week, your videos helped me a lot 😄

learned lib.pipe and noogle, thx!

Hey, I tried doing this back in December. My Nix programming is super basic, so it was quite an experience trying to actually format and manipulate data. Curious to see how you approach it.

Nice talk ❤ couldn't find anything more general online about nix deployment

I have to admit, your reaction to all of the Ps getting deleted was quite funny :) Thanks for tutorials. leard a lot!

FINALLY, I couldn't figure out how to read these and couldn't find any resources. Thank you :) EDIT: Okay, using it as a pattern AND as an expression seems rather confusing: but at least I can read more hackage source now :P

I have to say, I really don't like nix's syntax. I understand it has to be purely functional for it's purpose but, the inherit keyword feels redundant when using let-in blocks and makes everything harder to grok, IMO

This is probably the best introduction to monads I have seen. It also perfectly demonstrates the beauty of Haskell

Perfect timing, I was trying to add a vim plugin to nixpkgs 2 days ago, but failed xD. Thanks a lot!

Hey, great episode (as always)! ❤ Wanted to ask which LS you're using in neovim for nix (nixd, rnix or other?) and how have you configured it (nvim / non-nvim stuff) to show the "pseudo"-types of the `lib.` functions in the completion hints

This doesn't seem to work any more? :( poetry2nix is now maintained out-of-tree.

The clip length on a youtube list is 5 and a half hours! Is it on purpose?

just letting you guys know these walkthroughs are greatly appreciated! i'm learning a lot from these focused sessions.

It seems that DefaultDependencies=false should be set.

What plugin do you use to have browser windows windows within tmux?
