reykjavik

didn't age well.

So they laid off a guy who worked there for 20years, and is crazy passionate about the company? Good job, mozilla.

Used to work with cryengine some time ago. That is by far the worst c++ codebase i've ever seen.

That is really interesting point. Could you give an example when you avoided project because of understanding of categories?

Watched that guy's lectures and conference talks. While it's quite interesting and educative - I still don't get the "for programmers" part of it. I don't quite get how I would jump from understanding categories, morphisms, monoids etc. to building actually better systems. There are zero practical examples in his talks. Is it because i'm not using functional languages or what am I missing here?

*relational (damnit!)

The use-case listed there (the change of address) can be implemented perfectly fine with any rational or non-rational database. I personally would not switch to a completely new database and new paradigm just because of the requirement to show user's address based on the date. And for data that changes a lot - time series db still seems like a better choice.

So what's the real use-case?

What's the use-case for time-travel queries vs. just using time series databases? (ie. influx, timescale, kdb etc.)
