 Karen did not approve my PR last night, said that left a comment. I could not find the comment.

So in the morning she wrote that she has a question, whether the functionality on GET has changed.

I had to admit that it did. Now I don't return `null` when the value is not defined in Mongo. Her idea was that for our users it can be a surprise.
I think not, but OTOH, who knows those frontend people. 

Anyway, Karen was happy, approved the PR, I merged it to master, deployed to prod, and decided to test it tomorrow. Too exhausted today.

Started working with converting one project from Scala 2.11 to Scala 2.13. Found it depends on one tiny ancient project of ours, which does not have a 2.13 version (as if it's important), so decided to tweak that one. A small project, but converting it to 2.13 is just a torture. So far no progress.

We have a DLL hell in Scala world. I'd love to switch to Rust, where no such thing is possible. But sbt is totally crazy. Also discovered that when using sbt of version above 1.4, you bump into tons of stupid new errors, hardly documented, it's all about "libraries compatibilities". Hey, Yokota? You are not there anymore... shit...

Oh, btw. During that "we are hiring now" meeting, a couple of engineers insisted on not going, during the interviews, too deep into Scala mysteries, and instead check if the candidate can investigate a server failure. Сельские механизаторы нах.
