Dogs don’t say goodbye but to make up for it they say hello three times.
This paper says SQL would be better if it kept NULL but got rid of UNKNOWN. (I agree... and @morel_lang does this.) pure.ed.ac.uk/ws/portalfiles…
First rule of semantics. When anyone uses the word "semantics" they almost always mean something different than when I use the word "semantics". Especially if they work in marketing.
Submitted my SIGMOD paper (co-authored with @JohnFremlin). Now I can sleep.

The LookML project now has a few PRs cued up (parser, schema, schema-validator) for review. I'd welcome reviews, issues logged, improvements to the documentation. Hopefully we can get a 0.1 release out and onto Maven Central in a couple of weeks. github.com/hydromatic/loo…
LookML deserves a good open-source toolchain written in Java. I've created github.com/hydromatic/loo… and hope to get to a 0.1 release with a parser and schema validator in a few weeks. Not much there yet, but contributions welcome!
AethraDB is a research prototype that uses @ApacheCalcite to generate Java/GraalVM query plans over @ApacheArrow data. Performance looks promising. pure.tue.nl/ws/portalfiles…
Regime change in the Middle East sounds like a good idea, for once

In many programming languages, there are two ways of a specifying a sort: a comparator function, and a sort key. From a theory-of-computation perspective, is the comparator function strictly more powerful? Or can you always devise a (infinite?) sort key to match it?
Is there a way to swap out Siri on my iPhone for my preferred AI, say Gemini? Ditto Android and Alexa. It’s analogous to having a choice of search engine in your browser, but will shape the big-tech competitive landscape.
