I love this idea: duckdb.org/community_ex.... It translates dplyr syntax _inside_ of duckdb so you can mix it with regular SQL

Awesome opportunity to contribute to open source ML tooling at @posit.co (f.k.a. RStudio), a Public Benefit Corp AND Certified B Corporation. Posit sells enterprise software that allows them to hire FTEs that contribute to open source projects, and now their OSS ML team is hiring for a Python dev! 💯

Found this on LinkedIn but truer words never spoken. Stop the Python project "dependency hell" and make the switch to Python's {uv} framework. Here's a great YouTube video that really resonated with me being an R first dev... From Posit's Julia Silge: youtu.be/pMVYl9fx1EE

In 2022, inspectors described a “cascade of failure” at one foreign factory. The FDA barred it from shipping drugs to the U.S. — then excused more than 20 drugs from the ban, despite risks to consumers.

A ProPublica investigation found that for more than a decade, the FDA gave substandard factories banned from the United States a special pass to keep sending drugs to an unsuspecting public.
