Refactored `chatblade.nvim` to use `llm`, and renamed the project to `llm.nvim`. It's archaic compared these agentic MCP workflows, but it's completely replaced Googling programming related questions.

Tinkering with dltHub's REST API source to ingest data without having to write any bespoke code, and DuckDB's new local web UI, and I feel so spoiled with how good data tooling is getting!

Joe Naso and I just published an e-book covering the essential topics needed to build a data platform!

Check it out if you're looking to learn more about data modeling, ingestion patterns, and common data architectures.

Did you know Dagster asset checks can directly access data from an asset using the built-in I/O manager. Here's a quick snippet showing how it's done!

Turns out it's pretty easy to render 3D models with p5js! Here's how I'm embedding models in blog post markdown with Nuxt, Nuxt Content, and p5.

I don't find myself using recursion too often in the day to day, so I'm pretty happy with how elegant this solution turned out for day 7--computing all combinations of arithmetic on a sequence of numbers.

If you fall into the niche of data engineers who use both Neovim and Dagster--I'm working on an extension to improve the developer experience!

If you're looking for something cursed this Halloween. Here's how to query Dagster's GraphQL API directly from DuckDB to get asset materializations.
