Pretty short.

Ok, I got up at 2:30 at night, with strange paranoia; went downstairs, opened my work comp, and was reading Karen's complaints that HEAD requests return 400 on services on the new server. Eventually reacted rather stupidly that it's probably because of the new server configuration.

Then I opened Grafana, and looked at the graphs of memory gobbling. Last several hours: almost 0 (not exactly a zero, but it can stay like this for a couple of months. Then I looked at the graph for the last couple of weeks. Dramatic. SREs had to kill the process every day at about 4PM Eastern. Then I look at the graph for the last 8 weeks. And I saw why they started doing it. Before they did, the wave was going up-up-up, twice higer than the level they started killing it - and then magically it was going down. Probably there was some "direct memory garbage collector" that was turning on when the memory was reaching the limit. That's how it was.

Anyway, since there's hardly any gobbling now... I had updated my doc, and felt rather happy about all that. And went back to sleep.

In the morning checked what's going on: nothing.

At 11AM EST, when I just got out of my class, I wrote a "status report" via slack on my phone, a one-liner: "all done with 11107, problem solved".

Then, when I got home (it's about 6 minutes of fast walk), I went to the meeting, and there was no meeting. Everyone was reporting on slack. Cool!

Later I had a chat with Jeremy, who was given a task to upgrade one service that uses Play framework, from Scala 2.11 to Scala 2.12 - Jeremy was over-optimistic, so I showed him my branch, my efforts, and suggested to cooperate over a common library, and adapter library, that would make our code with business logic independent from those Lightbend idiots. He'll look into it. At least he knows now that it's impossible to convert a Scala 2.11 Play app to a Scala 2.12 Play app in a week. Or in two weeks. That's why we have some projects that have been in such state for the last 5 years. 

So, maybe together with Jeremy, who is really talented, we could do something doable. We will see. 

Then I had dinner, and now I'll get back to my work computer.
