But it Vortex and the other new formats are on my radar

I don't know much about it, but even faster random reads won't help Kafka if the shared table is organized by some business dimensions rather than by Kafka offset.

Which will be proprietary platform stuff I assume, so not going into the Iceberg spec? Is there any chance of caching layers also being open and standardised?

Ha! The Blondlot example is fascinating. Sometimes you can fail so spectacularly that they have to invent new math controls just to prevent future people from making a mistake as bad as yours. That's a special kind of immortality.

But no, I was not offended 😄 Keep on writing it how you see it!

He could easily have framed it in a more positive way. But either way, I don't think it matters too much, your readers are intelligent and can benefit from both, and see the criticism from a more positive angle (picking the bits they like from both).

Your post was valid from that scale. Winston's response took issue with it because he's been thinking very deeply at the macro-scale of power systems that run our entire planet. And I appreciate his views there. But, I think it was an unfair take out and needlessly combative.

I think it's a matter of scale. For me, your post is from the position where you are at day-to-day, your subjective experience, helping run a company, pushing back on some of the BS you see in the industry (which we love!), all inextricably linked to your past.

Next time, I'll agree it's Wednesday 😆

Like how to write an if statement or loop in bash 😄 I swear my brain is incapable of remembering that.

It really makes me question how ready it is for autonomous agents. I'm still on the "I'll believe it when I see it" camp for AI agents.

At this point, I can't tell if coffee makes me feel better in the morning because I am in withdrawal, or it actually picks me up.

The abstraction seems to make sense to people. And it isn't complicated either which is nice.
