For the first time in five years, I see aggressive advertising from the network of local senior living homes – literally, there’s a large banner at every location.

I wonder why?

1. Hypothesis one: Since March, for obvious reasons, a lot of spaces have become available, and they need replenishing with new r̶e̶s̶i̶d̶e̶n̶t̶s̶ (stricken through) tenants

2. Hypothesis two: Marketing decided that now is the perfect time to advertise senior living to those who are concerned about the lives of their grandmothers and grandfathers. Supposedly, it’s safer there.

My first pancake is lumpy on a 3D printer. The part turned out, but it failed the test as an adapter for a manual coffee grinder to a vegetable slicer. Besides the fact that I failed to check the direction of the motor shaft rotation (it was the opposite of what I needed), it’s clear I should have recalled some material strength – the pusher is objectively weak. But now I know how to design a part in CAD from scratch and get it in plastic within a few hours. Printer – Ender 3.

A very interesting lecture on molecular biology. It largely duplicates the high school curriculum, but it’s much more interesting and understandable. On one hand, it seems like I didn’t hear anything particularly new, but I do feel that concepts are better coming together in my mind after a good presentation.
