Coolest thing I learned is to clone trees. Roughest thing I learned is that most people who talk about climate, don't really want to plant trees. They just want to talk about it.

I learned how to localize sound events by the differences in the sound arrival time.

And I learned how to keep sub microsecond time accuracy.

Then I put the two together and made a raspberry pi sound localizer.

That I was happier after I was laid off than I was employed writing software. Other software developers online seemed to relate but absolutely nobody in the real world (non-developers) could understand it.

Learned the art of fermentation and started to make my own fermented hot sauces.

Currently enjoying a two week fermented Carolina Reaper hot sauce!

Time's ticking, make it count! Life's too short to let inaction be the boss.

Chatting with an AI is a more productive way of finding answers then googling for them.

Swimming 3 times a week for about 45 minutes changes the body and mind.

And is a little addictive like ex. running.

Background: I've been swimming for the last few years for about 10-20 minutes twice a week and I've experienced the changes.

Switching few months ago to more intense sessions led to dramatically higher rate of the change and I start to think about the ways of sustaining this. For now I've bought the swimming paddles and this works.

Organizing a wedding, is SO exhausting.

After it happens, you’ll have more time to play with AI :D

Swimming. I have submechanophobia. I went from never having put my feet in a children's pool to swimming in the ocean near Mantas and Baby sharks.

How to design a microcoded CISC CPU, then a RISC CPU. Nothing fancy in terms of getting modern applications to run on it, but it was a lot of fun seeing how much faster it could be than the CISC CPU. I've been looking into FPGAs but maybe I should just pick one and take the plunge.
