I wanted to use Subversion to checkout one of my GitHub repo branches, because an svn checkout only downloads the files it needs, not a full copy of every file ever added. But I discovered that GitHub sunset Subversion integration earlier this year. Sad face. Still, I suppose the economics justify that decision. As a consequence of my research, which was a bit sketchy because there is still heaps of documentation out there referring to the GitHub features which no longer exist, I did happen to learn about:
In this video I take a good long hard look at the entirety of this book.
The book is Basic Electronics – Volumes 1 through 6 written by Van Valkenburgh, Nooger and Neville, Inc. and published in 1955.
The book is about the state of electronics at the time it was written. It was commissioned by the United States Navy, who used it to train their technicians. Later, it was released for civilian use.
In the book there is lots of material on vacuum tubes, which were state of the art at the time. The sixth volume adds material on transistors and frequency modulation, which were bleeding edge technology at the time.
I learned heaps from reading this book, particularly about the various types of vacuum tubes (also known as “valves” by the British): diode, triode, tetrode, pentode, and Klystron, among others.
Also I learned that the name “transistor” is a contraction of “transfer resistor”, I didn’t know that!

I want to install some software to check it out (MySQL and MySQL Workbench) but I’m having trouble making it work on Debian. So I decided to spin up an Ubuntu instance for this job. I picked Kubuntu 24.04 (Ubuntu with KDE Plasma desktop) and this is my first go at using Ubuntu 24.04. Figured I should document the installation experience, which I have done here.
I recorded this video back in September 2023 but forgot to upload it at the time, so releasing now for the archives.

I organized my USB cables drawer. Left is USB 2.0, right is USB 3.0. Front is Mini-B and iPhone cables (including Lightening cables), middle is Micro-B (5-pin and 10-pin) and Type-A, back is Type-B. Conspicuously absent are Type-C which are filed in a different drawer. Also front-right are adapters, switches, hubs, and there’s even a USB light in there.
This is an old video I found while tidying up my files today. I recorded this back in September 2023, around about a year ago. Figured I might as well publish it on Elliot’s Extras.
