  1. JUL 4

    Read/Write/Nil with Michael Knyszek and Michael Pratt

    Please read important erratum at end of these notes! Astute listeners will notice that this is the first episode in over a year. I recorded not one but two awesome interviews...and then failed to edit and publish them. Guilt over this haunted me. I have finally accepted I must declare moral bankruptcy on this front to be able to continue the podcast; I apologize. (I may yet bring those episodes back to life, but I will no longer block on them.) In this episode, Michael, Michael, and I discuss an awesome debugging adventure deep in the Go runtime and linux kernel. Links: * Go issue: https://github.com/golang/go/issues/73581* Metastable Failures in Distributed Systems: https://sigops.org/s/conferences/hotos/2021/papers/hotos21-s11-bronson.pdf* Sponsor: https://sketch.dev/ Erratum: I described elided nil checks as working by mapping the page at 0x0 as read only. In fact, it is unmapped, so that reads will also fault. Silly me.

Most modern LLMs are decoder-only.* I messed up readability at Google. It means approvability, apparently. 🤷

    Iota: Rolling Hashes and FastCDC

    No guest for this inaugural episode--just me this round. I cover the basics of rolling hashes and FastCDC, which appears to be the state of the art in content defined chunking. Mentioned in the episode: 8 bit hash bugFastCDC paperPerkeep (once called Camlistore, oops)buprsyncI know the audio is slightly subpar (to say nothing of the content). But I think I know how to improve for next time. Finding my feet. :) Feedback welcome: josh@sigpod.dev

    The plan: Guests teach me substantive topics in software engineering, and I ask dumb questions. Please send guest suggestions, topic ideas, excitement, and monopoly money to josh@sigpod.dev
