In "Authorize, don't authenticate," I argue for the elimination of the login screen in applications that manage your personal data. You should be authorizing apps to access your data, not authenticating for the privilege of handing it over! blog.marcua.net/2026/07/31/a...

Any data engineers in my network or on #databs looking for a short-term contract setting up a Databricks-based ingestion/analysis pipeline? Would be for an academic lab studying the platform economy in collaboration w/ NYC gov. Happy to connect you!
end of an era. the lesson one should not take from this is that human annotation/labeling is over, but the players have changed. scale, surge, companies that work at larger scale, have taken over.

For designers to work outside a codebase, you have to keep wireframes and implementation in sync. To that end, I'm sharing Figmimic, a bookmarklet that copies any website or webapp into Figma in an editable state. Try it: marcua.net/minitools/fi... Blog post: blog.marcua.net/2026/05/05/f...
A fine use of CLAUDE.md: a coworker instructed their agent to use Ska bands as example constants in tests. If you're wondering, the examples are geographically spread across the US (not internationally) and the later waves of Ska. They will be on `main` soon.
Donate $30 to an educational non-profit or open-source project and I'll credit you $30 toward The Consensus Standard subscription. I'm excited to support these organizations with you! theconsensus.dev/subscribe.html

I've been working on this over the last few months and in my opinion it is just beyond cool. Grammar of graphics for SQL users!
I am excited beyond description to lift the veil on what we have been working on in 2026: Please meet ggsql! A new extension of the SQL language for creating visualisations using the grammar of graphics. Read all about it in the blog post or visit the website at ggsql.org
Late last year, I gave a talk at Northeastern to students in a few software engineering classes about what's changing and what's staying the same for junior engineers in industry with the introduction of coding agents. Slides and notes here: blog.marcua.net/2026/04/08/a....
I made a tiny tool for quickly sharing small datasets (< ~1000 rows) without uploading any data to a server. 🔗 ziptbl.com It compresses the data into the link itself, so there’s no account, hosting, or storage layer involved. Here's Florence Nightingale's famous 📊 data: ziptbl.com#d=eNpdlE-LGz...

"...managers who treat AI as a productivity multiplier for their junior engineers are optimizing for output. The managers who use AI to push their juniors into harder problems are optimizing for growth. These look similar on a quarterly roadmap. They produce very different engineers over two years."
Very useful post from Bryan breaking down the challenges of growing engineers in the land of AI
I want to talk about why AI-based mass surveillance is so dangerous, and why I would oppose it no matter which party or president is in office.

If you find yourself in Las Vegas, The Punk Rock Museum is a pretty good place to go! It's like 50% nostalgia for whatever 1-2 decades of punk you liked, 50% stuff Fat Mike / NOFX liked or collected.
