Today on lobsters there was a link to the Descent3 Source Code. Very cool.

In this video I pull the floppy disk out of the cover of my copy of The SCSI Bus and IDE Interface: Protocols, Applications and Programming (2nd Edition).
I have this wonderful old book The SCSI Bus and IDE Interface: Protocols, Applications and Programming (2nd Edition). It was published in 1997 but is still available for purchase through Amazon.
The book comes with a floppy disk (that’s right: a floppy disk!). I had to buy a USB floppy disk drive to read it. I have made the content from the disk available in a tarball, here: scsi.tgz.
If you just want to read the files, those are here:

Silly Job Title: Master Planner
This video is part of the New Book Teardown feature of my video blog.
In this video I take a look at Learning the Art of Electronics: A Hands-On Lab Course by Thomas C. Hayes and Paul Horowitz published in 2016. The book has 1,140 pages and is a companion to The Art of Electronics 3rd Edition.
Some notes about things of interest we noticed in the book:
- Xilinx was an American technology and semiconductor company, now owned by AMD
- the Ebers–Moll model is useful for modelling Bipolar junction transistors
- Hysteresis is the dependence of the state of a system on its history
- Wien’s bridge is used for precision measurement of capacitance in terms of resistance and frequency
- Wilson current mirror is a three-terminal circuit that accepts an input current at the input terminal and provides a “mirrored” current source or sink output at the output terminal
- a Bessel filter is a type of analog linear filter named in reference to Friedrich Bessel who developed the mathematical theory
- the video about the 6502 I watched recently is: The 6502 CPU Powered a Whole Generation!
- the Cypress PSoC is a family of microcontroller integrated circuits by Cypress Semiconductor

The Brain User’s Handbook: A Neuroscience-inspired Guide to Peace of Mind
I am reading The Brain User’s Handbook: A Neuroscience-inspired Guide to Peace of Mind which has this awesome image I want to share:
ViewVC Security Issue History
Today I found myself reading the Security Issue History from the ViewVC project. I thought it was instructive to see what actual (known) vulnerabilities looked like for a small software project over a twenty year period.
Setting query timeout for MySQL or MariaDB
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!
Dependency Injection in MediaWiki
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.
Extreme late binding
There’s a famous quote from Alan Kay that you will see bandied about:
OOP to me means only messaging, local retention and protection and hiding of state-process, and extreme late-binding of all things.
I think I agree with him, but I often find myself wondering quite what he meant by “extreme late-binding”. I suspect he means that object instances can redefine stuff they inherited from their concrete class. If your OOP platform doesn’t support that, you can emulate it with data and API.
