AI agents + Marimo notebooks = Python on autopilot. Letting AI write and check my Marimo code is a total workflow upgrade. The --watch flag and marimo check catch errors fast and keep me moving. Would you try this? Repost or comment! buff.ly/6LDN1RV #python #datascience

What if your coding agent could remember your preferences? AGENTS.md lets you train your LLM agent like an employee. This one file made my workflow smoother—no more repeating myself! Would you try this? Repost or comment! buff.ly/LinjaUs #.aiagents #.devtips

Still fighting Python environment headaches? I’ve moved to pixi—automation and new tools are the future. My Data Science Bootstrap Notes now use pixi, uv, and AI. This is my recommended workflow for 2025. Would you make the switch? Comment or repost! buff.ly/MoXJJhL #.datascience #.python

Finesse distinguishes exceptional data scientists from merely competent ones: Recognizing when you're stuck, creating progress markers, and finding creative workarounds. Has developing finesse transformed your effectiveness? ericmjl.github.io/blog/2025/3/... #DataScience #ProfessionalDev

🐍 Just fixed a frustrating PyPI upload error: "license-file introduced in metadata version 2.4"

The solution? Switch from setuptools to Hatchling as your build backend.

This is pretty cool! What version of VSCode does it require? I'm noticing that I get a VSCode version error (regardless of whether I'm on VSCode or Cursor). Can't wait to test-drive it!

🧬 Why is machine learning with preclinical biotech data so challenging? Combining public datasets with internal lab data isn't as simple as it seems, and why we should think "decision support" rather than "pure ML". Read more: https://buff.ly/42lQnmi #datascience

1/ When do you actually need LLM agents? After months of building agent tooling, here's the key: They're only useful once you have variable inputs paired with constrained actions. Don't jump the gun.
