Yes, spark is too complicated for most cases;

But if you're inclined to use it, databricks' setup of spark just saves you an incredible amount of time that you'd normally waste on configuration and wiring infrastructure (storage, compute, pipelines, unified access, VPNs etc). It's expensive and opinionated, but the data engineers you need to deal with spark OOM errors constantly is greater. Also databricks' default configs give you MUCH better performance out of the box than anything DIY and you don't have to fiddle with partitions and super niche config options to get even medium workloads stable

These are truly the best! And I've done a lot of research. Nowadays there are some smaller luxury brands that are closer with feature parity but not quite. The original Fossil team spun off to develop some kind of general watch platform, so I'm hopeful we'll see a remake by the time my fossil kicks out.

When I first moved to vienna, I also decided to check out Cafe Central. I ordered a tea (cost 5€). A teapot arrived, with a teabag on the side that I was supposed to brew myself. But the water was lukewarm, not nearly hot enough for tea. I complained to the waiter (dressed in something like a tuxedo). He dipped his finger in my teapot!! Then begrudgingly brought me new water lol.

A substantial contributor to that heat is asphalt and concrete though (absorbs heat and releases it at night). And to make it worse there's no tree cover. Winter is also more manageable if you don't have to wait 20 mins for a bus in an uncleared snowbank just because non-car mobility is second-class

Claude has a free slack client that I briefly was able to access by creating a new slack workspace and adding it there. But as of yesterday it wasn't working for me

The only plugin I found useful was the diagramming one, forgot what it's called. But you can quickly make code (or other) flowcharts etc. And browsing in rare cases.
