We just shipped a verified Coginiti node for n8n. That means you can orchestrate Coginiti catalog assets and run SQL/CoginitiScript inside n8n workflows, right alongside the systems teams actually live in like Jira, Slack, and Snowflake.

Say it loud⊠âAI coding agents can produce syntactically correct code. However, they donât produce useful layers of abstraction nor meaningful modularization. They donât value conciseness or improving organization in a large code base. We have automated coding, but not software engineering.â

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).

Today I interviewed a candidate for a sales role who had faked most or all of his LinkedIn profile. Not just exaggerations, but manufactured roles. Named dropped connections I'd be in no position to easily confirm (Satya Nadella). Oddly this isn't the first time and it's always been sales people.

There are lots of tools for data quality floating around out there, but you could be leveraging your existing data platform rather than some third-party compute platform to run those tests. Here is a guide for moving your Great Expectations tests to native SQL:

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.

Calling it a âknowledge graphâ was a mistake and it grinds the gears of the epistemologist in me. Knowledge is factive. These systems store claims, not truth. We shouldâve called them something weaker like information graphs.
