    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.

  • Iota: whisper.cpp
    Mar 27 2024

    Links:

    • my little whisper.cpp bug fix
    • why the logits were calculated inconsistently
    • wav2vec2 on arxiv and huggingface
    • the openai whisper asr model announcement
    • beam search patience
    • top notch guide to CTC
    • the bitter lesson (and in meme form)

    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. 🤷
