Did I just learn you can use an underscore as a thousand separator in Python? yes :-(
Do I prefer `1_000_000` over `int(1E6)`?
Did not decide yet...
I find that for doing quick analysis, understanding data, and pretty much everything that is not full blown coding and research- the AI interface of @warpdotdev is preferred over interface of VScode/Cursor/etc.

Starting from v1.4, DuckDB will also be able to produce Polars Lazy DataFrames. These include both projection and filter pushdown directly to DuckDB :-)
As easy as doing a ".pl(lazy=True)" in your DuckDB relation.

Quarto is 100x better than Jupyter IMO 🙈
1️⃣ Reproducibility
Jupyter lets you rerun chunks inconsistently 😳
2️⃣ Advanced Formatting
Quarto = full control over output styles. Styling Jupyter is a Nightmare.
3️⃣ Version Control
.qmd are plain text, not .ipynb
Ever tried it?

A confession from an #rstats die-hard...
@DataPolars and @posit_pbc's new Positron IDE is making me enjoy doing data wrangling in #Python...
😬

Good first impressions with Positron. RStudio-like plot/file/environment explorer for #Rstats, Jupyter-like Python support, while simultaneously editing a Dockerfile and #Nextflow script github.com/posit-dev/positro…

A student in our lab converted from Pandas to Polars for data frame manipulation in Python. One analysis dropped from 20 minutes to 5 seconds. Hat tipped.

All wars end with negotiation, but it's hard to negotiate when the other side's bargaining position is "you all die and disappear."
