Semantic Compression
Casey Muratori explains his approach to not-so-object-oriented design (he calls it procedurally-oriented) and refactoring (he calls it compression): Semantic Compression.
Today I added procedurally-oriented to my spell check.

Silly Job Title: Tome Pumper. I am the Tome Pumper!
In this video we take a look inside the Encyclopedia of Electronic Circuits.
The pages which have circuits I thought were interesting and will consider building are: 358, 415, 420, 520, and 597.
Here are the pages I scanned while working through the book:

Deep Work
A new post from Justin Sung: How to Effortlessly Enter DEEP WORK on Command. I assume “deep work” has something to do with Deep Work: Rules for Focused Success in a Distracted World. But basically I guess they are talking about flow.

I’m famous!
As I was flipping through the July issue of Silicon Chip magazine, I wasn’t expecting to see this!
How to Force Your Brain To Be Motivated (when you don’t feel like it)
DFUZ:
- Distinguish; feelings from thoughts from actions
- Fake; act like a motivated person and do the actions
- Uptime; spend more time on tasks as you get better at it
- Zone; make sure your environment is distration free, if you find yourself distracted make a note about what distracted you so you can remove it in future
I found Justin’s TEDx talk over here: Stop Studying. Start Learning.

Silly Job Title: Surge Sage.
In this video we have a look at an old book, the Student Manual for the Art of Electronics (find on archive.org). This old book references The Art of Electronics 2ed, but The Art of Electronics is up to 3ed now. In this video we just flip through the book to see what is inside.
This book is made obsolete by Learning the Art of Electronics 2ed, which is an ongoing project of ours.

New Book Teardown #7: Electricity and Magnetism 3rd Edition (2013) | In The Lab With Jay Jay

Silly Job Title: Prime Hack.
In this video we tear down Electricity and Magnetism 3rd Edition written by Edward Purcell and David Morin and published in 2013.
Electricity and Magnetism is one of the books I am taking notes for as a part of my Learning the Art of Electronics project. These notes are a perk for people who support me on Patreon, so what are you waiting for!? :)
There is a website for the book maintained by the publisher, but regrettably there’s not much there, just some material available to instructors only: https://www.cambridge.org/Purcell-Morin
I mention two xkcd comic in the video, those are these: Farads and Nerd Sniping.
The “esu” is prounounced as “eee-ess-you” and is also known as the Statcoulomb.
I mention the Franck–Hertz experiment which happens to be something I wrote a Hackaday article about: A DIY Version Of The Franck-Hertz Experiment.
The first edition of Electricity and Magnetism was volume two in a five volume course: Berkeley Physics Course.
The books mentioned in Chapter 1 include The Flying Circus of Physics and How Things Work.
The websites mentioned in Chapter 1 are:
The Feynman (1977) reference is to The Feynman Lectures on Physics which is also available here: www.feynmanlectures.caltech.edu
The symbol: ∇ (“nabla”, an upside down Δ “delta”) is the vector differential operator and its key uses are:
- ∇f → gradient of scalar
- ∇·F → divergence of vector field
- ∇×F → curl of vector field
- ∇² → Laplacian
The Big Clive video that I mentioned was this one: How a stungun creates 20kV from a 9V battery.
I also mention the show’s wiki, the ITL Wiki, which is on the web over here: https://www.inthelabwithjayjay.com/wiki/
