Your identity and your project history sit inside GitHub, and none of it is yours to take with you. The AT protocol, the same one under Bluesky, changes the arrangement. Your data lives in your own account. It travels with you, and any app can build on it. That makes the forge swappable and your reputation portable. It also fits what's coming: once AI agents are opening most of the pull requests, you'll want collaboration on open rails anyone can build on. Five minutes on why the AT protocol is where this is heading. false https://talks.nixcon.org/nixcon-2026/talk/7VCF7M/ https://talks.nixcon.org/nixcon-2026/talk/7VCF7M/feedback/ A Lightning talk 2026-09-26T16:50:00+02:00 16:50 00:05 None nixcon-2026-104217-lightning-talk-antithesis Sponsored en Placeholder false https://talks.nixcon.org/nixcon-2026/talk/9TL88V/ https://talks.nixcon.org/nixcon-2026/talk/9TL88V/feedback/ A Lightning talk 2026-09-26T17:00:00+02:00 17:00 00:05 None nixcon-2026-103264-how-long-until-it-s-done-techniques-for-build-farm-dashboards Jacek Galowicz en Staring at a private Hydra instance and guessing when a massive build will finish is a completely solved problem, yet most teams are still flying blind. While the official NixOS project enjoys real-time ETAs and granular bottleneck metrics, you are likely suffering through multi-hour black-box builds simply because your own Hydra traps its telemetry inside a raw JSON blob. In this five-minute lightning talk, we will see how to unlock that data and get official-grade observability for your own build farm without patching Hydra or maintaining a custom exporter daemon. By dropping in the off-the-shelf Prometheus json_exporter, we can map Hydra's native output into over fifty scrape-able metrics purely through configuration. We will walk through the exact setup to visualize queue depths, catch failing remote builders, and build the real-time ETA burndown panel. false https://talks.nixcon.org/nixcon-2026/talk/KNRVXR/ https://talks.nixcon.org/nixcon-2026/talk/KNRVXR/feedback/ A Lightning talk 2026-09-26T17:10:00+02:00 17:10 00:05 None nixcon-2026-104212-lightning-talk-clan Sponsored en Placeholder false https://talks.nixcon.org/nixcon-2026/talk/PWVQFK/ https://talks.nixcon.org/nixcon-2026/talk/PWVQFK/feedback/ A Lightning talk 2026-09-26T17:30:00+02:00 17:30 00:05 None nixcon-2026-104213-lightning-talk-cyberus Sponsored en Placeholder false https://talks.nixcon.org/nixcon-2026/talk/W7YLBZ/ https://talks.nixcon.org/nixcon-2026/talk/W7YLBZ/feedback/ A Lightning talk 2026-09-26T17:40:00+02:00 17:40 00:05 None nixcon-2026-98936-nixos-on-riscv liberodark en Hi, I'd like to present my work on RISCV. I've currently ported Nixos to the SpacemIT K1 and I'll be working on the K3 soon. I hope to finish before NixCon and present it there.

In this workshop, you will see why NixOS is *the* alternative to Yocto for modern embedded development, offering reproducible builds, atomic updates, and simplified dependency management from day one. We start from an empty repository, building a complete computer-vision product from the ground up. You will learn to cross-compile for your hardware, integrate custom software, and implement hygienic build practices that drastically reduce evaluation times and improve testability. By the end of this session, you will leave with a proven blueprint for defining, customizing, and tuning NixOS for any embedded platform, giving you total control over your production pipeline. false https://talks.nixcon.org/nixcon-2026/talk/AWWCUK/ https://talks.nixcon.org/nixcon-2026/talk/AWWCUK/feedback/ A Lightning talk 2026-09-27T16:10:00+02:00 16:10 00:05 None nixcon-2026-104214-lightning-talk-jane-street Sponsored en Placeholder false https://talks.nixcon.org/nixcon-2026/talk/E9P9Y7/ https://talks.nixcon.org/nixcon-2026/talk/E9P9Y7/feedback/ A Lightning talk 2026-09-27T16:30:00+02:00 16:30 00:05 None nixcon-2026-104215-lightning-talk-pdt-partners Sponsored en Placeholder false https://talks.nixcon.org/nixcon-2026/talk/AJB7DM/ https://talks.nixcon.org/nixcon-2026/talk/AJB7DM/feedback/ A Lightning talk 2026-09-27T16:50:00+02:00 16:50 00:05 None nixcon-2026-104218-lightning-talk-determinate-systems Sponsored en Placeholder false https://talks.nixcon.org/nixcon-2026/talk/VQXBLD/ https://talks.nixcon.org/nixcon-2026/talk/VQXBLD/feedback/ A Lightning talk 2026-09-27T17:10:00+02:00 17:10 00:05 None nixcon-2026-104216-lightning-talk-flox Sponsored en Placeholder false https://talks.nixcon.org/nixcon-2026/talk/3A9NNU/ https://talks.nixcon.org/nixcon-2026/talk/3A9NNU/feedback/ A Short talk 2026-09-27T17:30:00+02:00 17:30 00:20 None nixcon-2026-104190-closing-ceremony en Join us as we ceremoniously wrap up NixCon 2026! false https://talks.nixcon.org/nixcon-2026/talk/XRNDVL/ https://talks.nixcon.org/nixcon-2026/talk/XRNDVL/feedback/ B Short talk 2026-09-27T12:00:00+02:00 12:00 00:20 None nixcon-2026-102404-when-the-honeymoon-ends-supporting-nixos-based-products-for-the-next-five-years Martin Messer en You’ve just built a phenomenal product on NixOS. The declarative configuration is beautiful, and the reproducibility is flawless. Then the honeymoon phase ends. Your industrial hardware is deployed into the real world, and suddenly you’re faced with a five-year lifecycle. To make matters more complicated, upcoming regulations like the EU’s Cyber Resilience Act are demanding rigorous CVE tracking and compliance. Upstream NixOS moves fast and is an incredible foundation, but maintaining those products in production for half a decade is an entirely different beast. Pinning to a release is great, but after community support ends, you hunt down vulnerabilities and backport security fixes to keep auditors happy. We had to solve this, so we built CTRL-OS. This talk is a behind-the-scenes story of how we manage a downstream, enterprise-grade NixOS distribution designed to survive the long haul. We will walk you through the lifecycle of our daily operations, including: * How we decide which packages to commit to supporting. * Our methodology for identifying and patching security vulnerabilities. * How we keep customers in the loop, turning raw data into actionable advisories for their security and compliance needs. * The pipeline we use to safely ship everything to customers in production. false https://talks.nixcon.org/nixcon-2026/talk/UNQZSX/ https://talks.nixcon.org/nixcon-2026/talk/UNQZSX/feedback/ B Short talk 2026-09-27T13:30:00+02:00 13:30 00:20 None nixcon-2026-102507-adding-to-the-pile-or-how-to-extend-nixpkgs Yannik Sander en Nixpkgs is a vast collection of packages, yet sometimes we need to add our own modification or additional packages to it. The intended way to do so are overlays which are composable extensions of package sets. Still, while documentation on overlays exists, the details behind package sets such as mkScope, mkExtensible, etc. remain relatively elusive. In this talk I will shed some light on this increasingly consistent architecture of nixpkgs, point out ways to automate and where automation fails. false https://talks.nixcon.org/nixcon-2026/talk/WQK7QC/ https://talks.nixcon.org/nixcon-2026/talk/WQK7QC/feedback/ B Short talk 2026-09-27T14:00:00+02:00 14:00 00:20 None nixcon-2026-103269-build-it-all-yourself-and-prove-it-air-gapped-nixpkgs-with-hydra Jacek Galowicz en How do you guarantee absolute software supply chain security without locking your developers into a restricted environment? In highly regulated industries, the standard answer is painful: force all development into offline, air-gapped environments. But Nix offers an elegant alternative. Because Nix cleanly separates network-fetching from building, we can decouple developer velocity from compliance. Developers can work in unrestricted environments while releases are rebuilt from scratch behind the air gap to prove (to authorities) that an exact verified set of unchanged sources led to our binaries. In this talk, we share a concrete blueprint for building all of Nixpkgs entirely offline. We cover: - How to develop freely and use air-gapped Hydra builds to produce a 100% trusted, verified binary cache. - The practical cost of sovereignty: carrying an audited ~1TB seed (one disk, one hash) across the gap, and rebuilding all of Nixpkgs on standard hardware in a week. - How content-addressed seeds and pinned evaluations create a replayable record of your software for decades to come. Regardless of which critical regulated industry you work in, you will leave with a proven recipe to achieve total digital sovereignty without sacrificing modern developer workflows. false https://talks.nixcon.org/nixcon-2026/talk/YWPHWG/ https://talks.nixcon.org/nixcon-2026/talk/YWPHWG/feedback/ B Long talk 2026-09-27T15:00:00+02:00 15:00 00:45 None nixcon-2026-104219-spontaneous-lightning-talks en Come talk about your stuff! false https://talks.nixcon.org/nixcon-2026/talk/3SFNY8/ https://talks.nixcon.org/nixcon-2026/talk/3SFNY8/feedback/
