Fast finality for Cardano 💥 Another week of progress on Peras! • Ledger support for forecasting on-chain Peras parameters merged • More progress on ObjectDiffusion • Promising Buck2 experiments for faster testnet builds Full update | 16 October 👇 tweag.github.io/cardano-webs…

Final day at BazelCon 2026! It's been a great few days in Amsterdam, catching up with familiar faces, meeting new ones and chatting all things Bazel. If you're here, there's still time to stop by the Tweag booth and say hello!

Missed Guillaume Maudoux’s talk at BazelCon 2026? Guillaume took to the stage yesterday to present “Managing Configurations Explosion 💥” If you missed it, you can catch his talk in the @bazelbuild livestream on YouTube! Watch here: youtube.com/live/mPzunhMxbpQ…

3M+ configured actions. 500k actual actions running. At BazelCon, Tweag’s Guillaume Maudoux will present “Taming Configurations Explosion,” covering reset transitions, path mapping and option scopes used to reduce configuration redundancy. 14 October | 14:45–15:15 | Room 5–8

Peras weekly update - Initial testnet setup launched with the latest Peras code enabled - Historical certificate database MVP under internal review - Peras CIP and design document revisions continued - A PR was opened to forecast Peras protocol parameters for the current epoch.

Aleksandr Bantev thought running a Nixpkgs team was hard. Turns out it's not! Read about his experience in our latest blog post: tweag.io/blog/2026-10-08-run… #nix #nixpkgs

Giving AI agents access to your funds? What could possibly go wrong? 👀 Day 2 at @token2049 Singapore @KrisKowalsky took to the @Cardano booth today to talk about AI agent security, who controls their decisions and how to make sure safeguards actually work. AI is moving fast. Security needs to keep up !

Docker builds shouldn’t be the slowest part of CI. At #BazelCon Training Day, Tweag’s Rafael Lima will lead a workshop on using Bazel, rules_oci and rules_img to assemble container images through a graph-based approach, independently of a local Docker daemon. 13 Oct | 09:00–10:30 | Room 11–14

Day 1 at @token2049 through our camera roll. From Fahmi Syed's Midnight keynote to Frederik Gregaard talking real-world assets at the Cardano booth. Tomorrow it’s @KrisKowalsky's turn: autonomous AI agents for security auditing, with on-chain payment settlement.

Settlement in as little as 2 minutes. That’s what Peras is working towards for Cardano. Last week: the initial protocol parameters implementation was merged, with progress on certificate handling and testnet tooling. 2 October full update: tweag.github.io/cardano-webs…

Amsterdam is next. Tweag by Modus Create will be at #BazelCon 2026 from 13–15 October. Our engineers will share practical work on high-velocity container builds and taming configuration explosion at scale. Come and meet us at our booth.

Topiary v0.8.0 -- Irresistible Ironwood -- is out! 🌳 The headline feature is Tree-sitter language injection support, for formatting embedded code. That brings Markdown with fenced code blocks, full OCamllex and experimental Menhir support with embedded OCaml, and JSON in Rust. Also new: much richer error reporting, better multi-line string formatting for Nix and Nickel, and a --check flag for CI. github.com/topiary/topiary/r…

DRep Monthly Call is back this Wednesday at 3pm UTC. @blockjock2017 will be joining us to chat about what’s happening with DRep Council and how to join. We’ll catch up on the current governance actions too, with plenty of time for questions. Sign up, you don’t need to be a DRep to join: luma.com/usylji51

Seven years later, Nix flakes are still experimental. At NixCon 2026, Tweag’s Valentin Gagarin will explain why he changed his mind about flakes and why he thinks the controversy was never really about the technology itself. 📅 27 September 🕘 09:00–09:45 📍Room A

AI coding agents are only as good as their memory of how to use your tools – and in long sessions, that memory tends to fade. In our latest blog post, Victor Nascimento Bakke introduces tricorder-mcp, an MCP server for Tricorder, Tweag's Haskell dev tool. He explains why an MCP server holds up where a skill file struggles, and walks through a real feature built with Claude Code. Read more: tweag.io/blog/2026-09-24-tri… #Haskell #AI #MCP #DevTools

Who’s heading to @token2049? 👀 Modus Create’s @KrisKowalsky will be at the Cardano booth, speaking about autonomous AI agents for security auditing and on-chain payments. See you in Singapore.

Sandboxed Nix builds are great. Rebuilding for the 42nd time? Less so. At NixCon 2026, Tweag’s Guillaume Maudoux will talk about Nixception: fast incremental builds without giving up sandboxing, using the same cache inside and outside the sandbox. 📅 26 September 🕝 14:30–15:15 📍Room A
