AI coding tools speed up how we build data-driven apps. But legacy database access patterns slow us down. Join us for a live hands-on workshop to learn how ADBC makes database access faster, more portable, and better suited to analytical and agentic work. Register on Luma:

We just joined the Open Semantic Interchange, an open source initiative to create a vendor-neutral standard for semantic metadata. Every tool defines metrics in its own format. OSI fixes that with one shared spec. This is what semantic intelligence needs to scale: open standards, not walled gardens.

The NEW Designing Data-Intensive Applications dropped on my desk this morning and at 600+ pages it landed with a thud! If you work in data, this book definitely belongs on your shelf. It's undoubtedly one of the most, if not the most, important and relevant data systems book you could read.

Grateful for the chance to speak at the Charlotte SUG this week! The talk opened with a simple observation: we've been telling data and analytics executives to get their data ready for AI for over a decade. Long before LLMs were a household term, the data readiness gap was already the bottleneck.

Clickhouse raised a $400m round D, bringing their private funding in the $1.15B range. Thatâs pretty close to where SNOW was pre-IPO, though it looks paltry next to DBRX. They've also added a Postgres service, further cementing Postgres as the transactional system for builders (and agent builders).

In software engineering we have blue-green deployments, but in data it's write-audit-publish, or if you've got real data quality problems, audit-write-audit-publish. Both patterns can be implemented as data testing strategies using CoginitiScript.

In 2025, too many congratulated themselves on AI progress using the wrong measures. Lines of code added. Pull requests opened. Teams saying they âfeel faster.â Those are activity metrics that we long considered junk. They are easy to inflate, easy to celebrate, and largely meaningless.
