We’re super excited to announce our speaker lineup for Planet Nix 2025! You can see the speaker list on the [Planet Nix website](https://planetnix.com). We’ve got two full days of talks and workshops on a wide range of topics from the details of the Nix evaluator, to secrets, and setting up a Chromebook alternative. We’ll see you there!

Was there a recording for room 104 on March 7th? I would like to listen to @Ericson2314 's talk
> Sandstone: Fast incremental Haskell builds using dynamic derivations
I checked the SCaLE YouTube channel but there doesn’t seem to be a recording for that room on that day.

There was no recording, but I’ll put the slides in the repo or something. I would rather just read @fzakaria’s blog posts than watch a video, too :).

This was one of the most exciting developments in Nix that was demo’d at Planet Nix! Nice work John @Ericson2314. Looking forward to seeing the slides and a link to the repository as well.

They will be split up, and I’m sorry there wasn’t a recording of the workshop room. No one told me about this until after the conference 😞

No worries. Thanks for all the effort on everyone’s part organizing this, it ended up being one of the best conferences I have ever been to.

Bummer.
I didn’t realize that as well.

Thanks for the slides! I was disappointed when I realized there wasn’t a recording, but all the blog posts and the slides are very valuable as a replacement!

I see the Scale videos, but can’t find the Planet Nix videos. Unless they are embedded in the larger list.
Pointers?

**tiny reminder:** the **[PlanetNix 2026](https://planetnix.com/) CFP is officially open.**
If you spoke last year, we’d _love_ to see what strange, brilliant, reproducible (or irreproducible) things you’ve been hacking on since.
If you didn’t speak last year… well, this is your moment to fix that.
We’re looking for talks + workshops on:
- Nix at work or at home or at the neighbor
- Cross-compiling, reproducible builds, or tales from the cursed dimension
- Hydra, GitHub/GitLab CI, build farms, binary caches held together with hope
- Onboarding, dev experience, making Nix less scary for your teammates
- Any tricks, hacks, or dark magic you discovered in unstable
And yes, we know how this usually goes:
you think “I’ll submit later,” and suddenly it’s the final hour and you’re writing your abstract with three terminals open and one eye.
**This is your gentle, friendly, garbas-to-you nudge to submit before that happens.**
(Your future self — and the reviewers — will thank you.)

See you in Pasadena!
