Hey there NixOS Community,
The Nix Vegas organizer team is proud to announce a CFP and initial sponsorships for Nix Vegas, the first Nix Community event at the DEF CON 33 Conference, August 7-10 2025:
The theme of this year’s DEF CON is Access Everywhere:
Imagine that we’re building the digital commons from scratch. What could we do to make sure everyone benefits? How would we make it a freer, healthier place to inhabit? How do we protect each other from the worst parts of the current system?
- Services should be usable no matter who you are.
- Services should be accessible no matter where you are.
- Services should not violate user privacy or security.
Anyone who has pushed to staging knows that we don’t have to imagine - we rebuild the world all the time. 
If you would like to participate in the CFP, check out the site or go straight to Sessionize. This is our first community event at DEF CON, so we are curious to see what kind of interest there is in giving talks.
Our first two sponsors are System76 and Protectli, two hardware manufacturers. If you are interested in sponsoring, send us an email at <sponsor at nix dot vegas>.
As always, keep on Nixing,
Nix Vegas Organizers

We are happy to announce some additional sponsors: Ampere Computing and Next Computing. They will be providing the aarch64 side of the build farm and binary cache we’re trying to host at DEF CON this year. 
For more information, including how to sponsor and submit a talk, see https://nix.vegas/. We will have upcoming announcements about our official artwork, as well as other fun things to do at the DEF CON 33 Nix Community soon.
We hope to see you at DEF CON!

Couple announcements for this weekend:
THANK YOU to both Flox (@ron) and Determinate Systems (@grahamc) for helping out with funding our speaker operations. Both our Sessionize instance and a limited number of DEF CON Human badges for accepted speakers are paid for. This will make it cheaper for people to attend DEF CON, and easier for people to give great talks. 
See our CFP page for how to submit talks (and get your badge sponsored by Flox if you’re accepted), or jump straight to the Sessionize. The CFP is scheduled to close July 5, so get them in!
Keep on nixing,
The Nix Vegas organizers

Rebuild The World
We’re excited to announce our artwork and theme, by Kenz Tobias. Our theme this year is Rebuild the World, and it shows in our artwork of the World Tree Yggdrasil.
If you’d like to learn more about our amazing artwork, and the Nix Community at DEF CON 33, check out our blogpost. 
P.S. Yes, there will be stickers and possibly other swag

Final schedule and speaker bios for Nix Vegas are up on the site and Hacker Tracker:
https://hackertracker.app/schedule/?conf=DEFCON33&tag=48148
We decided to do an extended CFP in our first year to allow people to have plenty of time to come up with content, and wow did the community deliver! Despite it turning into an all nighter while we pieced the final schedule together, we have 12 accepted talks over two days, including a DEF CON Community Stage talk.
If you can’t make it to DEF CON, we plan on streaming and recording the sessions. (Does anyone have a good example of a nginx RTMP config that restreams to Twitch and YouTube? )?
Thank you for the amazing turnout this year, and we are all excited for DEF CON later this week!
