If you didn't know, you're about to that August 6, 7, 8, 9 was DEF CON 34 and Nixers were definitely present. Join Alex, Chris, Morgan, Jared, Dan, Tristan and I for a recounting of Nix Vegas, the official Nix space at the latest DEF CON.

We finally figured out why 2,000-year-old Roman concrete survives in seawater while our modern concrete crumbles in decades. The Romans used "hot mixing" with lime clasts. When the concrete cracks and rainwater seeps in, it dissolves the lime, recrystallizes it into the cracks, and literally heals itself. We need to start building like this again.

"When you constrain a problem, beauty emerges."

"If two build systems both promise you a hermetic, reproducible closure, then there must be a transformation from one to the other and back. Otherwise one of them is lying."

"I proposed the Linux kernel for one small feature, what I got back was a full VM"

All the talks from #DEFCON34 and #NixVegas are up !

I captured mine with a small summary:

* Relocatable Binaries
* Guix by Nix
* How to piss off your Nix friends

The @NixVegas team is going to do a few posts debriefing about the different parts of this year's event once we get a little post-DEF CON sleep. Badge, CTF, and network were all extremely unique engineering challenges with Nix at the forefront. Amazing teamwork from everyone

[Nix Vegas @NixVegas]

Choose DEF CON. Choose agency. Choose the NixCTF. Choose getting your PR merged, and the Nix Party. Choose pwning Hydra. Choose Nix Vegas.

We have like seven TP-Link powerline ethernet adapters this year so people can PXE boot to play Bad Apple or run NixOS from anywhere in the LVCC during @defcon, lmao

These parking signs - as seen in @santamonicacity California - should be illegal.

Three more hours, get your CFP submissions in! https://t.co/kHj8zZje3A

Starting the @NixVegas cache mirror on our core router. We've got a 20Gbps trunk for a thing. We have two SATA SSDs with 32Gbps L2ARC in front, TBD if we have room for a mirror or stripe and if raw NARs from https://t.co/9cXVxvglf3 or unpack/ZFS dedup are smaller

Place your bets

Anyone have samples or a source for the Milk-V Duo Module S? Supply evaporated b/c @RadxaComputer is switching 8 to 64 GB eMMC. I hate begging on Twitter, but it would be great to find it, even the board I got months ago is impossible to find now.

Ghostty is leaving GitHub. I'm GitHub user 1299, joined Feb 2008. I've visited GitHub almost every single day for over 18 years. It's never been a question for me where I'd put my projects: always GitHub. I'm super sad to say this, but its time to go. https://t.co/DQDemHdytV
