Oxide and Friends

Oxide raised its $100M Series B round of venture capital. Oxide's founders, Bryan and Steve, answer questions selected by Adam from social media about the round, the company, and the future.

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

Oxide's $100M Series B

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.

Adventures in Data Corruption

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.

When Async Attacks!

On the heels of Bryan's blog post about the similarities between aspiring college athletes finding a team and entrepreneurs raising a round of capital, Bryan and Adam were joined by Robert Bogart to discuss his own experiences with both--and the life lesson accrued along the way.

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

Diving In with Robert Bogart

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.

AI Discourse with Steve Klabnik

Late in 2024, an economics paper captured the attention of the world. AI, it claimed, had a tremendous impact on materials research, disproportionally benefitted the most productive, and--sadly--reduced job statisfaction. It now appears that the results are entirely fabricated! Ben Shindel joins Bryan and Adam to discuss.

Solutions Software Engineering with Matthew Sanabria

Last week the kerfuffle between Synadia and CNCF, tussling over the ownership and futures of NATS, bled into the public. The outcome may cast a long shadow for open source and for the CNCF. Bryan and Adam were joined by Rachel Stephens and Adam Jacob to discuss how we got here and possible outcomes.

Postscript:

The CNCF updated its blog with proof that the ACH transfer of $10,000 was completed [still very funny! -ahl].

Derek Collison--as reported by Runtime News--has agreed to transfer the NATS trademark to the CNCF "because we just feel that the damage to the ecosystem and the ugliness is not worth it for anyone."

The Oxide Friends pour one out for Optane, Intel's great hope that never managed to find traction.
