Engineering write-ups from Vetra: the systems we build in Rust. Architecture, war stories and measured numbers.https://vetra.se/enhttps://vetra.se/blog/gunnar-a-git-server-with-no-database/https://vetra.se/blog/gunnar-a-git-server-with-no-database/A git server in Rust that spawns nothing, stores no database, and boots as PID 1 on bare metal. Refs persist through an Apache Arrow IPC log, stock git is the judge, and a fetch costs 21 MB where the best rival needs 262 MB.Fri, 07 Aug 2026 00:00:00 GMTinfo@vetra.se (Rickard)https://vetra.se/blog/korp-one-app-over-the-whole-data-path/https://vetra.se/blog/korp-one-app-over-the-whole-data-path/Spark pipelines, a live graph, time-travelling Iceberg tables and maps in one Rust app. The whole data path runs from a single command, and the entire UI state dumps to JSON so tests need no display.Thu, 06 Aug 2026 00:00:00 GMTinfo@vetra.se (Rickard)https://vetra.se/blog/tunnr-a-distroless-wireguard-appliance/https://vetra.se/blog/tunnr-a-distroless-wireguard-appliance/A bare-metal WireGuard VPN client in Rust: no shell, no package manager, one binary as PID 1, and the tunnel up before any other packet leaves the box. Plus a pure-Rust harness that boots it under UEFI and proves it ran.Sat, 25 Jul 2026 00:00:00 GMTinfo@vetra.se (Henrik)https://vetra.se/blog/garmr-a-one-person-soc-in-rust/https://vetra.se/blog/garmr-a-one-person-soc-in-rust/Why the 2026 security landscape splits into agentic platforms without infrastructure and Rust infrastructure without a brain, and what it took to build the intersection: one binary that ingests, detects and lets an LLM investigate every alert for half a cent each.Fri, 24 Jul 2026 00:00:00 GMTinfo@vetra.se (Henrik)
