I’m trying to get my head around the electronics I have been building recently. I have put together a web page which I can use to compare the implementations of the brightness and darkness detectors from the Maxitronix 20in1 projects I have built lately: Brightness and Darkness.

This video is part of the New Book feature of my video blog.
In this video I review the venerable The Art of Electronics 3rd Edition by Paul Horowitz by Winfield Hill published in 2015. This monstrous tome includes some 1,220 pages.
This is a long video, because this is a long book!
While I was writing up these notes for the video I found a wealth of fun stuff. Here are a few links:
I happened upon the selectSQLText function in the MediaWiki source code and learned how to set a query timeout in either MySQL or MariaDB. Good to know!
Today I read the documentation for how Dependency Injection is done in MediaWiki.
I had a few small nits to pick (such as their statement that services should be stateless) but… fair enough.
For myself I don’t usually use Dependency Injection and a Service Container, instead I prefer the Service Locator pattern which I find is simpler and more economical to use, especially in PHP where there is a single process per request.
