Oxide's $100M Series B

After raising $200M in February... we raised another $445M in July! Your favorite computer company is capitalized to the gills--enough to weather the supply chain upheaval even! Come for co-founders Steve and Bryan describing the raise; stay for tax, debt, and credit talk with Scott Orn. In addition to Bryan Cantrill and Adam Leventhal, our special guests were Steve Tuck and Scott Orn.

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. Some of the topics we hit on, in the order that we hit them: Rittel and Webber, Dilemmas in a General Theory of Planning (1973) Wikipedia: Cynefin framework HOPICS Kiip Noah Harlan: "Why We Started Kiip" Findhelp: "Transforming CBO Case Management with Kiip" AlleyCorp findhelp.org MTS: "AI Doomsday Predictions Lack Real-World Reality" with Bryan Cantrill Eric Ries, Incorruptible If we got something wrong or missed something, please file a PR!

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. How do you test configurations you haven't built yet? Steve, Andrew, and Rain join Bryan and Adam to talk about the transformative power of the Oxide emulation environment, VOXEL, and how it has accelerated development in many domains. In addition to Bryan Cantrill and Adam Leventhal, speakers included Steve Karam, Andrew Stone, and Rain Paharia. Previously, on Oxide and Friends: OxF s03e06 - Rack-scale Networking (P4 and DDM with Ry Goodfellow) OxF s01e26 - The Pragmatism of Hubris (with Cliff Biffle) OxF s03e09 - Get You a State Machine for Great Good (Wicket with Andrew Stone) OxF s01e25 - Tales from the Bringup Lab OxF s01e18 - Dijkstra's Tweetstorm OxF s03e31 - Hiring Processes with Gergely Orosz 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!

More and more, people are relying on AI to do their writing for them. Is this the new normal, or the intellectual equivalent of claiming take-out is your own home cooking? Max Spero, founder and CEO of Pangram, joined Bryan and Adam to discuss how they distinguish AI and human authorship. In addition to Bryan Cantrill and Adam Leventhal, our special guest was Max Spero.
