I’m reading Practical IoT Hacking: The Definitive Guide to Attacking the Internet of Things and it mentioned some equipment I’m interested in:
I’m reading Pro Git and I learned that GitHub maintains a list of .gitignore templates. Those might come in handy.

In this video I take a look at Electrical Engineering 101: Everything You Should Have Learned in School…but Probably Didn’t 3rd Edition written by Darren Ashby and published in 2011.
In the book the author mentioned that they used to write for chipcenter.com which appears to have since been taken over by EE Times. ChatGPT provided more information.
The author also mentioned Mathcad. I’m planning to check that out over here: https://www.mathcad.com/
And some terms which came up (ChatGPT explains further):

Note: this video is nearly five hours long! If you’re interested but don’t have 5 spare hours (and who does??) you might like to listen at 2x speed or more. The standard YouTube interface only supports playback up to 2x speed but I have some notes about YouTube hacks you can use to set the playback at 3x speed… or more!
In this video I teardown “Radio Engineering” (3rd edition) by Frederick Terman published 1947.
Frederick Terman was a Doctor of Science which is what the Sc.D. after his name stands for. It’s like a Ph.D. He is remembered as a father of Silicon Valley.
In the book there is much talk of diodes, but of course that is in reference to the old thermionic diodes which were vacuum tubes. These days diodes are semiconductors made from something like silicon or germanium.
The book talks a lot about power amplifier classes. Today the same classes are still used, it’s just that anything other than class AB and class D are very uncommon.

This is a part of the homework feature of my blog, which is an ongoing conversation with my mate S.F.
Hey mate. Lovely to see you again, as always.
I ended up getting these cards printed at clickmedia.com.au to take with me on Wednesday to ElectroneX:
I mentioned Iain McGilchrist, he’s a psychiatrist who dabbles in philosophy. I think he has a really excellent and interesting view of things. It’s hard to summarise his position but he is very interested in the difference in perceptive capabilities of the left and right hemispheres of the brain. He has a YouTube channel over here: @DrIainMcGilchrist and if you search for him you will find many a fascinating interview.
You told me to check out Succession (TV series).
I found the Four Corners video you mentioned, over here: Self-defence or genocide? Asking Israel’s powerful voices about Gaza | Four Corners.
I mentioned Eben Moglen, who has a website over here: moglen.law.columbia.edu. I find Eben inspirational. He’s always talking in grandiose eloquence about the importance of free software, if you search for him on YouTube you are bound to find something of interest.
I mentioned Annie Jacobsen, she’s a pretty interesting cat. She has written a number of books on conspiracy-theory-like topics. I recently read her book Nuclear War: A Scenario.
I have a note here that says “positive view on nihilism” but I forget what that was about. Something I wanted to tell you, now lost to time. But searching for ‘positive view on nihilism’ turns up a bunch of interesting results! (Oh. Wait. Found it! It’s a video I wanted you to see: Optimistic Nihilism.)
Oh, another note I don’t remember: “void of ‘huh'”. I assume we were being hilarious.
There is an urban myth that the first human projectile that made it into space was a manhole cover from nuclear testing facilities for Operation Plumbbob in 1957. I dunno if it’s true, but it’s a good story!

Silly Job Title: Electron Enchanter
This video is part of the New Book Teardown feature of my video blog.
In this video I take a look at Beginner’s Guide to Reading Schematics, Fourth Edition by Stan Gibilisco published in 2018. The book has 209 pages.
Some things which came up during the video:
From the Wikipedia article on Bifilar coil: A bifilar coil is an electromagnetic coil that contains two closely spaced, parallel windings. In electrical engineering, the word bifilar describes wire which is made of two filaments or strands. It is commonly used to denote special types of winding wire for transformers. Wire can be purchased in bifilar form, usually as different colored enameled wire bonded together. For three strands, the term trifilar coil is used.
From the Wikipedia article on Power dividers and directional couplers: Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used mostly in the field of radio technology. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another circuit. An essential feature of directional couplers is that they only couple power flowing in one direction. Power entering the output port is coupled to the isolated port but not to the coupled port. A directional coupler designed to split power equally between two ports is called a hybrid coupler.
From the Wikipedia article on Waveguide: A waveguide is a structure that guides waves by restricting the transmission of energy to one direction. Common types of waveguides include acoustic waveguides which direct sound, optical waveguides which direct light, and radio-frequency waveguides which direct electromagnetic waves other than light like radio waves.
The list of parts suppliers from the back of the book (some have closed down):

Today I discovered Newton’s own annotated copy of his Philosophiæ naturalis principia mathematica.
Today my free copy of the Altronics catalog arrived. This is low-tech, but still the best way to keep up to date with the state of the art: just read the catalog from cover to cover!
I thought I might start with some of Paul Graham’s famous papers which aren’t about Clojure per se, but are about Lisp:
Also his book On Lisp is of interest and is available free online these days.
And then the Arc language tutorial, which is also not Clojure, but looks like an interesting Lisp.
Then I will read the following books, in this order:
This is, of course, a silly amount of reading. Let’s see how I go.
