Sad day as Todd Snider, the last of the great pot smoking barefoot hippie folk singers, has passed. I probably saw Snider at least a dozen times and my kids grew up with him in the background. We're all the poorer now.
Songwriting Legend Todd Snider Has Died - Saving Country Music
The world has lost a light, and of the most unique, interesting, compelling, challenging, mercurial, iconoclastic, and influential songwriters to ever ply the craft. Todd Snider wasn't just a singer o...

ADBC drivers in #Java? Yes. The latest release of ADBC adds a JNI layer that lets Java apps load drivers, run queries, and fetch results fast in @arrow.apache.org format. Read the new blog post from @ian.columnar.tech and David Li for examples and perf comparisons vs. JDBC. Link in comments👇

Happy release day, Drive-By Truckers dropped two and half hours of remix/remastered tracks along with a bunch of live performances. This is the only DBT I need in my life 😂

We were touring the Roman Forum today when we thought we heard a small explosion followed soon by a rush of sirens. We saw the fire crews and police later after leaving the Colosseum. Glad to learn there were no fatalities.

The 2025 MAD Landscape is out from Matt Turck. After ten years of explosive growth in the landscape, the team decided to narrow the products and companies represented by almost half. Now the most remarkable thing about the landscape is the curious choice over what's been included or excluded.

We love Apache Arrow, but when I learned about Arrow Database Connectivity (ADBC) I wanted it available for every data platform like yesterday. So I'm super excited for the launch of Columnar! #databs
The future of data connectivity is columnar. Today we launched
@columnar.tech to accelerate the shift from slow, row-oriented APIs like ODBC and JDBC to >10x faster alternatives powered by @arrow.apache.org. Learn more 👇

Looking forward to being at the GovAI Summit (Oct 27-29, Arlington VA) on behalf of Coginiti!
If you’ll be around, stop by our booth and let’s connect in person. And if you’re not at the conference but you'd like to grab a coffee (or whiskey🥃) while I’m in town, send me a message and lets meet up.

I didn't expect my first post on substack to be about competitors, but then the dbt labs/fivetran merger got announced. So here's a point of view from someone who doesn't use either, but in the space. tl;dr the merger doesn't change anything for most of us

One day the industry will recognize the drawbacks of AI agents and nondeterministic automation, and rediscover the UNIX philosophy of chaining together small purpose built tools in a low cost and predictable way, otherwise known as shell scripts.

Great turnout for our Low-Key data meetup in Raleigh last night. Wonderful catching up with so many regulars and meeting the new people that showed up! Lots of great conversations about people, processes, careers, and the personal highlight for me... meeting someone building ml for chicken sexing!

It’s really cool to see what’s getting built using the components of the composable data stack like Apache Datafusion, Apache Arrow, and Apache Iceberg. Cloudflare’s R2SQL is just another example of what’s possible. Hey @columnar.tech where is the driver for this?
