Oxide and Friends

The Oxide rack contains within it a distributed system that needs to trust itself. But how is this trust built? Bryan and Adam were joined by colleagues Andrew and Finch to explore how Trust Quorum was designed, built, and verified.

In addition to Bryan Cantrill and Adam Leventhal, we were joined by Oxide colleagues, Andrew Stone, and Finch Foner.

Building a Quorum of Trust in the Oxide Rack

Bryan and Adam were joined by members of the Oxide team to describe the multi-year search for a mysterious source of hardware failures. All related to an ultra-reliable--and yet still not reliable enough--component.

In addition to Bryan Cantrill and Adam Leventhal, we were joined by members of the Oxide team: Nathanael Huffman, Alan Hanson, Cliff Biffle, Eric Aasen, Robert "RFK" Keith, and Jordan Hendricks.

When Nine Nines Isn't Enough

Oxide raised a truckload of capital a few weeks ago to fund the business for the foreseeable future. Bryan and Steve describe the raise, and Adam poses the best the best (and worst) questions scraped from Hacker News.

In addition to Bryan Cantrill and Adam Leventhal, we were joined by Oxide CEO, Steve Tuck.

Shell Game with Evan Ratliff

Bryan and Adam were joined by Grady Booch, software engineering pioneer and living legend, to speak about the past present and future of software engineering. History doesn't repeat itself, but it does rhyme!

In addition to Bryan Cantrill and Adam Leventhal, we were joined by special guest, Grady Booch.

Some of the topics we hit on, in the order that we hit them (some LLM assistance):

SAGE • as foundational real-time distributed system
Software crisis • demand outpaced ability to build reliable systems
Margaret Hamilton • (SAGE → Apollo) and the term “software engineering”
UMLRational Software founded (1982); acquired by IBM (2003) • OO overshot via inheritance; core idea (objects as cognitive units) endured
 • LLMs are unreliable narrators - they 
cannot do abductive reasoning • Architecture = decisions with high cost of change
 • Core skills persist: abstraction, coupling, cohesion, judgment
 • Fear cycles repeat; fundamentals endure

Grady's Book Recommendations

Software Engineering Past, Present, and Future with Grady Booch

What do LLMs mean for the future of software engineering? Will vibe-coded AI slop be the norm? Will software engineers simply be less in-demand? Rain and David join Bryan and Adam to discuss how rigorous use of LLMs can make for much more robust systems.

In addition to Bryan Cantrill and Adam Leventhal, we were joined by Rain Paharia, and David Crespo.

Engineering Rigor in the LLM Age

Time for the annual predictions episode! Bryan and Adam were joined by frequent future-ologists Simon Willison, Steve Klabnik, and Ian Grunert to review past predictions and peer into the future. If any of these predictions come to fruition, it's going to be an interest 1, 3, or 6 years!

In addition to Bryan Cantrill and Adam Leventhal, speakers included Simon Willison, Steve Klabnik, and Ian Grunert.

Predictions during the show:

 • Adam
 • 1 year: AI companies go on an acquisition binge (especially for anything that smells like data)
 • 3 year: Crisis of AI slop open source (both projects and contributions)
 • 6 year: Jensen hands over the reins at Nvidia
 • 6 year: Tesla is out of the consumer car business
 • 6 year: With the iPhone market shrinking, Apple has several new attempts at the next potential flagship product
 • Bryan
 • 1 year: "Vibe coding" is out of the lexicon -- or used strictly pejoratively it becomes a named condition (for which Adam -- in an act of nomenclature genius rivaling The Leventhal Conundrum -- suggested "Deep Blue")
 • 1 year: A frontier model company has a prominent whitepaper making the case that AI will lead to broad-based prosperity rather than job loss
 • 1 year: Harvey.ai becomes the pets.com of the AI boom -- and a harbinger of the coming bust (which becomes known as a Correction-like euphemism)
 • 1 year: A prominent S1 has revalations of economic behavior that has an effect beyond the company's IPO
 • 3 year: Frontier models treat AGI as "already done" -- and ASI as a non-goal
 • 3 year: Custom-written software thrives in lieu of SaaS
 • 6 year: DSM adds LLMs as a substance that can induce psychosis
 • 6 year: $NVDA not beyond its November 2025 peak
Simon • 1 year: The AI for programming holdouts are going to have a nasty shock
 • 1 year: We're going to solve sandboxing
 • 1 year: Our own challenger disaster with respect to coding agent security - see 
the Normalization of Deviance in AI • by Johann Rehberger
 • 3 year: Something that seems impossible for a coding agent to build today - like a full working web browser - won't just be built by coding agents, it will be unsurprising
 • 3 year: We will find out if the Jevons paradox saves our careers as software engineers or not
 • 6 year: The number of people employed to type code into computers will drop to almost nothing - it will be like punch card operators. Those of us who write code today will have very different jobs that still build software and take advantage of our previous coding experience.
Steve • 1 year: Agent Orchestration will still be a hot topic. It'll be partially, but not entirely, solved. Updated with some more rigour: We won't have a "kubernetes for agents" just yet.
 • 3 year: Using AI tools when writing software professionally will be considered something closer to using autocomplete or syntax highlighting than something controversial or exceptional.
 • 6 year: AI will not have caused the total collapse of our economic and governmental systems.

OxF 2025 Wrap-Up

We hit a new (and disturbing!) failure mode recently when a production rack that had been up for several months saw every (!) compute sled's service processor become simultaneously unresponsive. Bryan and Adam were joined by the members of the Oxide team who debugged the vexing issue -- and reached its surprising root cause.

In addition to Bryan Cantrill and Adam Leventhal, we were joined by Oxide colleagues, Cliff Biffle, Matt Keeter, and Will Chandler.
