Planning a friendly intro to dbt for the 1st DS Lab of the year w/ Michael Chow, & the question came up of who the episode will be for. It'll rock for anyone curious about #dbt & data eng, obvs, but if you're a dbt pro, it will be a chance to come help others learn!! #databs #rstats #duckdb #pydata

infer 1.1.0, a package implementing an expressive grammar for statistical inference, is on CRAN! In a change originally motivated by @allendowney.bsky.social's posit::conf(2024) keynote, the package now supports arbitrary test statistics.

Thinking about running local models with coding agents like Positron Assistant? 💻

A new evaluation by @simonpcouch.com and @sara-altman.bsky.social suggests we aren't there yet. Between hardware hurdles and performance gaps, hosted models are still the best bet for now.

Local models are not there (yet) - Posit
LLMs that can run on your laptop are not yet capable enough to drive coding agents.

While coding agents like Positron Assistant and side::kick() are technically compatible with LLMs small enough to run on your laptop, the results leave much to be desired.

Curious what’s free in Positron vs. what comes with Positron Pro?
Nick Rohrbaugh shows exactly how Positron stays a full-featured free IDE — and how Pro adds SSO, managed credentials, scalable compute, auditing, and more.

A diagram containing four boxes with arrows linking each pointing left to right. The boxes read, in order, "R interface," "driver manager," "ODBC driver," and "DBMS." The left-most box, R interface, contains three smaller components, labeled "dbplyr," "DBI," and "odbc."
