Two years ago, the Oxide team encountered data corruption during a fairly simple network data transfer. The ensuing debugging sessions uncovered a truly bizarre bug involving CPU speculation! Bryan and Adam were joined by colleagues John and Rain to discuss the discovery and circuitous hunt to track down the bug.In addition to Bryan Cantrill and Adam Leventhal, speakers included John Gallagher, and Rain Paharia.Previous episodes mentioned:OxF s03e09 - Get You a State Machine for Great GoodOxF s03e20 - Shipping the first Oxide rack: Tales from ManufacturingOxF s04e25 - RTO or GTFOOxF s02e38 - A Debugging OdysseySome of the topics we hit on, in the order that we hit them:The Update FrameworkOmicron Issue #3441 (Oxide Computer GitHub)Omicron Pull Request #3455 (Oxide Computer GitHub)stlouis Issue #454 (Oxide Computer GitHub)Changing psrset.out.txt (Oxide Computer)Commit 5ec2885322423c0cca0d006611b5c9ac94b0f588 (Oxide Computer)Omicron Pull Request #3560 (Oxide Computer GitHub)If we got something wrong or missed something, please file a PR!

When Async Attacks!
What happens when the Oxide API is slow? A podcast episode! More specifically, one about how the team employed all manner of debugging techniques to track it down to one obscure and configurable async runtime feature! Bryan and Adam were joined by members of the team to talk about that journey and the tools we used (and made!) along the way.In addition to Bryan Cantrill and Adam Leventhal, we were joined by Oxide colleagues, Dave Pacheco, Eliza Weisman, and Augustus Mayo.Previous episodes mentioned:Oxide and the Chamber of MysteriesThe Saga of SagasDTrace at 20Cultural IdiosyncrasiesMr. Nagle’s Wild RideA Debugging OdysseyRTO or GTFOSome of the topics we hit on, in the order that we hit them:Falling in Love with RustTokio Runtime Builder – disable_lifo_slotmagic‑trace (GitHub)Magic Trace podcast episode from Jane Streetdiesel‑dtrace (GitHub)omicron issue commentqorbstatemaptokio‑dtracetokio issue #7411Visualizing Systems with StatemapsPostgreSQL WAL INIT ZEROStatemaps: Visualizing System Behavior (YouTube)The statemaps that we referred to:Nexus by thread, discussed starting at 55:29.

Debugger-Driven Development
Building systems software can be quite opaque, leading to the need for great debugging tools. At Oxide, we've found that debuggers can be even more valuable leading rather than following system development. Bryan and Adam talk with Oxide colleagues about how domain specific debugging tools help us build systems not only more robustly, but faster as well.In addition to Bryan Cantrill and Adam Leventhal, we were joined by Oxide colleagues, Dave Pacheco. John Gallagher, Alan Hanson, and Eliza Weisman.Previous episodes mentioned:OxF: AI Discourse with Steve KlabnikOxF: The Saga of SagasOxF: A Crate is BornOxF: The Network Behind the NetworkOxF: Bringing up CosmoOxF: RIP USENIX ATCOxF: Dijkstra’s TweetstormSome of the topics we hit on, in the order that we hit them:omdb ground rulesIf we got something wrong or missed something, please file a PR!
