Just published a post about building smart services at CLARK. A pragmatic approach that worked very well for us, going from heuristics to ML. Thoughts and feedback welcome! #datasky #data #databs medium.com/clark-engine...

Despite patriarchy's persistence, growing numbers of men believe they have it worse off than women. And, new research shows this "male victimhood" ideology is most common among men who aren't facing hardship.

S3 (Iceberg) Tables is everything I dreamt of, and more. I blogged some long-form thoughts: meltware.com/2024/12/04/s... I think we're about to see an explosion of data tools (@materialize.com, @clickhouse.com, @duckdb.org, et al.) learn to write Iceberg tables via S3 table buckets. #databs

New blog post! Big data isn’t dead; it’s just going incremental. But bad things happen when uncontrolled changes collide with incremental jobs. Reacting to changes is a losing strategy. jack-vanlightly.com/...
