Also, seaweed is at the bottom of the food chain -> lots of biomass supported by the ecosystem, less chance of accumulating anything toxic.

“Europe produces 0,2% of algae in the world,” he said. "But we import 500 million worth of algae every year.

Yup. I like seaweed, but most of the seaweed I like comes from Asia. Transporting it from far is not a smart move.

Being informed that “from now on, we’ll use Microsoft development tools” because our branch in $other_country decided to.

Soon after that, I informed the boss that I’d wrap my projects up (using development tools of my choosing) during the subsequent year, and then leave, and support the projects in future as a subcontractor.

So I went and started my one-person-company. It was hard, but so far it has worked.

That is quite a lot of interesting experiments, thanks for introducing. :)

I’m inclined to add one more:

51: monitor the radio spectrum for drones (and if their signature looks hostile, warn people about them) - there’s a DIY recipe for a monitoring station out there somewhere, and some Ukrainian guys scan their sky using HackRF

SDR is definitely a technology worth learning. I’m already a happy user of RTL-SDR, but if I want to really see what my WiFi is doing, I should get a HackRF eventually too. (Note: WiFi is too fast to intercept without loss, except with another WiFi card, unless a slower bitrate is deliberately chosen.)
