We've talked about Oxide's Root of Trust--the hardware underpinning the security of the product--but how do we keep a bad actor from spoofing Oxide to load malicious software? Philip Tricca joined Bryan and Adam to describe the key ceremony, the process of creating and storing the secret that plays a critical role in manufacturing. And we paid our respects to the dot matrix printers that made the ultimate sacrifice in the name of security.

In addition to Bryan Cantrill and Adam Leventhal, our special guest was Philip Tricca.

Wicked problems defy simple solutions. Even as we describe the problem, we may be presupposing particular solutions and narrowing scope. Our greatest, most persistent societal problems fit this model. Wicked problems may not be solvable, but progress can be made. Noah Harlan joins us to describe his technical entrepreneurship battling wicked problems.

In addition to Bryan Cantrill and Adam Leventhal, our special guest was Noah Harlan.

When the supply chain crunch catches up with you, sometimes a tiny resistor the size of a fleck of pepper is the difference between a world-class computer and... e-waste. Members of the Oxide operations and electrical engineering teams join Bryan and Adam to discuss how close we came to stopping production, for want of a resistor.

In addition to Bryan Cantrill and Adam Leventhal, speakers included Robert "RFK" Keith, Eric Aasen, Scott Tagwerker, and Steve Tuck.

We've been hosting a live show weekly on Mondays at 5p for about an hour, and recording them all; here is the recording.

Some of the topics we hit on, in the order that we hit them:

• voxel -- Virtual OXide Emulation Lab: emulated rack deployments on one Helios host (omicron on Falcon/propolis VMs, SoftNPU switches, FRR routers); optional real SP/RoT firmware via sp-emu. https://github.com/oxidecomputer/voxel
• Falcon -- tool for standing up virtual network/rack topologies of propolis VMs on illumos for testing. https://github.com/oxidecomputer/falcon
• Tofino -- Intel/Barefoot programmable switch ASIC (Tofino 2) in Sidecar; P4-programmable. Discontinued by Intel.
• SoftNPU -- software P4 target emulating the switch dataplane, so the stack runs without Tofino hardware. https://github.com/oxidecomputer/softnpu
• P4 -- DSL for describing packet-processing pipelines; how the Tofino/SoftNPU dataplane is programmed. https://p4.org
• Gimlet -- Oxide's compute sled.
• Sidecar -- Oxide's rack switch board, carrying the Tofino 2.
• raclette -- reduced-size lab rack (a few sleds + switch) used for dev/test rather than a full 32-sled rack. (my read; unverified)
• Hubris -- Rust microkernel/RTOS for the SP and RoT: statically-defined tasks, memory protection, synchronous IPC. https://github.com/oxidecomputer/hubris
• Humility -- debugger for Hubris systems; dumps tasks, stacks, ringbufs over SWD. https://github.com/oxidecomputer/humility
• a4x2 -- pre-voxel testbed topology: 4 emulated Gimlets, 2 SoftNPU switches, omicron on one Helios host.
• trust quorum -- rack secret split into shares across sleds; a quorum must be present to reconstitute the storage-encryption key, so a stolen sled is useless alone. https://docs.oxide.computer/guides/system/initial-rack-setup
• illumos -- open-source Solaris-derived OS; the host OS (Helios) is an illumos distro. https://illumos.org
• zones -- illumos OS-level virtualization; each control-plane service runs in its own zone.
• Scrimlet -- Gimlet attached to a Sidecar ("switch Gimlet"); hosts the switch zone, dpd, MGS.
• DDM -- Delay-Driven Multipath, the underlay routing protocol, implemented in Maghemite (ddmd, ddmadm). https://github.com/oxidecomputer/maghemite
• Dendrite -- dataplane controller; dpd programs Tofino or SoftNPU and exposes an API to the control plane. https://github.com/oxidecomputer/dendrite
• swadm -- CLI against dpd for port config, links, addresses, routes.
• A0 -- sled power state where the host is fully powered (vs. A2, standby with the host off); driven by the SP sequencer task.
• iCE40 -- Lattice FPGA on Gimlet/Sidecar for power sequencing and board glue logic. https://github.com/oxidecomputer/quartz
• PRs needed!

In addition to Bryan Cantrill and Adam Leventhal, our special guest was Max Spero.

Simon Willison joined Bryan and Adam to discuss a wild couple of weeks in AI. First, we have a high-profile, AI-induced, AI-diagnosed security incident. Next we have the rise of frontier-class open-weights models. Who's for or against open weights? Do they make for a more or less secure future? Exciting times!

In addition to Bryan Cantrill and Adam Leventhal, our special guest was Simon Willison.
