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.

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.

Errata:
* I referred in the show to LLMs as encoder-decoder models. Most modern LLMs are decoder-only.
* I messed up readability at Google. It means approvability, apparently. 🤷
In which I ramble about randomness and random algorithms. Now with theme music!

This was a fun and decidedly humbling conversation with Ben Johnson about SQLite, databases, Litestream, and LiteFS.

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:
I 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
