Cheat sheets

Coming soon.

Five one-page sheets, each the compressed form of a session: the checks, the patterns and the thresholds, on a page you can keep open while you work. None has shipped yet. Pick the one you want and we will tell you when it lands.

  1. Bayesian · PyMC

    PyMC model checking on one page

    The five sampler checks, their thresholds, what each failure usually means, and the three model-checking tools that come after them.

    Distils MCMC in Practice.

  2. Modeling · partial pooling

    Hierarchical models: how much to pool

    Complete, no and partial pooling side by side, the one plot that shows shrinkage, and the centered and non-centered forms with when to use each.

    Distils Hierarchical Modeling using PyMC in Baseball.

  3. Shiny · R

    Shiny module state patterns

    Return values, reactive arguments, session$userData and an R6 store, each with the one case it fits and the one it does not.

    Distils The No-Look Pass.

  4. LLM tooling

    The querychat data description

    A fill-in template for the schema and business rules that make text-to-SQL reliable, with the three test questions to run before handover.

    Distils Ask the Box Score Anything.

  5. Production · GitHub Actions

    Game-day pipeline checklist

    What a scheduled pipeline needs before it runs without you: the schedule, the secrets, the failure path, the log and the message that reaches a person.

    Distils Game-Day Automation.

One email when something new arrives.

First name and email. One message when the sheet you picked is ready, and no other mail. Replies reach a person.
