So pollution in China is plummeting due to the Coronavirus...

Oh the irony of naming a scientific discovery over someone whose entire platform is anti-education in nature. I cant tell you how many environmentalist organizations I had to stop donating to or participate in because they adopted her image too. She makes me sad :(

Interesting Fact of the Day:

Current climate change is happening at a pace 6.2 times faster than the climate change that resulted from the asteroid impact that killed the dinosaurs.

We have had 1.06 C change in about 150 years. The dinosaurs experienced a 4.5 degree change over 4,000 years. So for the dinosaurs it changed at a pace of 0.001125 C per year for us it has been about .007 degrees per year. So current climate change is happening 6.2x faster than it did during the extinction of the dinosaurs.

A little illustration showing my take on einstein's quote. What we know we dont know is simply a small, ever growing line between what we know and what we don't know we know...,

“As our circle of knowledge expands, so does the circumference of darkness surrounding it.” -- Albert Einstein

I wanted to kick off the #QotoJournal hashtag by sharing a free open-source book I started writing some time ago...

I started writing a book in an attempt to help explain how to do circuit analysis by hand. Originally it was going to include both time-domain analysis as well as frequency-domain analysis. The book is incomplete and I never got to cover the time-domain but has several complete examples showing frequency-domain analysis on many common circuits. I’ve gotten some compliments over the years, particularly from HAM radio operators, on how useful the book has been to them. I’d like to share here what I have so far in case anyone might find it useful.

As a side note if anyone would like to revive the project and work with me on expanding and completing the book it would be most welcome. Please feel free to contact me. In the meantime here is the compiled book in its current form. I don’t currently have the latex source code published anywhere but if there is any interest I will happily publish it and open-source it on github.

Here is a direct link to the book: https://discourse.qoto.org/uploads/short-url/tFY6qFBUnmFFVdnBErQ8mJdZuBF.pdf

You can also view the book as a feed in my blog here: http://jeffreyfreeman.me/frequency-domain-circuit-analysis-tutorial/

If you wish to comment or discuss it there is a discourse post for it here: https://discourse.qoto.org/t/frequency-domain-circuit-analysis-tutorial/41

Apparently MUF is around 20 Mhz right now. Not horrible for a solar minimum.

Almost done setting up my new system. I decided to design a whole new theme based on Rick & Morty / STEM, seems appropriate to share it on #QOTO.

This rice is brought to you by i3-gaps configured entirely from scratch

All the fies and details needed to replicate the theme on your on local system can be found here at the QOTO GitLab server:

Good morning everyone. I went to bed last night with a breakthrough. Finally got python's Goblin module working on the Janus GraphDB just moments before bed.

I'm super excited because that means the full tech stack is in place. full docker-compose environment, full integration tests. Everything I need for a perfect environment to start developing this project for real now!

Why is it so hard to get a good Role-model for climate change activism.

I used to be fairky active about climate change but now that Greta came along I had to distance myself from most organizations as many seem to praise or support her. It is such a shame we cant have role models in climate change we can look up to.
