Mostly a review of pretty standard methods, but some fun examples of enabling expression expansion (the magic behind column selectors!), more complex objects in a dataframe (models, vectors), and breaking the paradigm to go back to partitioned dataframes + list comprehensions

The way python and R foster inclusion directly contributes to their success: joyful places to exist, a steady flow of new maintainers, and a delightful collection of niche tools empowered by wildly different expertise coming together

NGL it's not perfect or right for all use cases (e.g. batch only, limited model types) so YMMV. Still some rough edges and bugs, too. I might not rush to deploy in enterprise tomorrow but definitely a project to watch and something I can definitely imagine using in some personal/volunteer work

Exciting because:
- dbt has some of the boilerplate needed for MLOps (tests, logs, orchestration)
- DBs integrated with other systems like CRMs/dashboard so its easy to serve predictions from there
But gotta tweak both orbital and dbt to get the most benefit, with an assist from {sqlglot}

A favorite part of my Chicago commute: walking past a building engraved “to safeguard wealth men established banks” that was built in… 1929
I’ve yet to find the complementary building that says “to safeguard banks men established the FDIC”

Benefits include staying reproducible, compartmentalizing your thinking/writing to focus on what matters, and writing final docs in Qmd plaintext for easier version control and collaborating with non-technical coauthors who don't have Jupyter spun up

This is useful bcs we can work in a linear order, reacting to previous views in our analysis. But then we can streamline our story to focus on takeaways instead of the analysis process

I have not gotten to kick the tires on @duckdb.org 's DuckLake yet as a technical solution, but deeply enjoying their release blog. It's a lovely piece that covers many of the bigger trends of the last ~5 years with heart, humor, and brevity

So many questions on this incoherent X AI sliding into my DMs
It thinks I’ll DM 1k random people one at a time?
Am I supposed to say “hi data scientist! My vibes say you have no data strategy so lemme tell you how to do your job”
Is it likewise putting my name on random lists?
Bizarre

Having to contribute to AI training data (for Captcha) just to fill out a contact form for my Congressman just kinda sums it all up...

The team explores the relationship between your Bayesian DGP and causal DAG and recommends using "causal queries" to be sure you're looking at implicity assumptions and backdoor paths

I always love the rigor at CDSM
The team talks about not just how to do a thing but how to simulate and study their understanding of the thing

Making things "pretty" has never been where I find the most joy in data work. So, I'm super excited about @posit.co 's {brand.yml} framework for adding unified styling across Quarto, Shiny, and more at minimal effort 🤩

Another awesome thing about @DataPolars (for #rstats folks and beyond) -- it inspires equally ergonomic open-source addons
Neat project here finally makes calc'ing model metrics in a df as easy as it should be like any aggregation

New Year, New Site -- after many hacks to preserve all my post / talk / RSS links, I'm finally ending 2023 by switching my blog down to Quarto!
Didn't write much in 2023, but I'm hoping Quarto's nice, lightweight framework will lead to a productive 2024
