Updated 03-Aug-2025 Read This Book on Sleep (2020) Bill Gates recommends the book Why We Sleep, and it is excellent. All of my notes above need to be revised with this book in mind.

Updated 03-Aug-2025 Update November 2023 This particular device has really held its value and its performance.

Updated 03-Aug-2025 Bash being the most common shell, it makes sense to learn bash shell scripting. I didn't think this at first and later came to the conclusion, having spent time with Fish Shell.

Updated 03-Aug-2025 Here are some ways of getting things tweaked. Your mileage may vary. Mint-Y-Dark This theme has some hardcoded colors in PNG files. Grayscale them with ImageMagick, as follows: for file in /usr/share/themes/Mint-Y-Dark/gtk-2.0/assets/*.png; do convert "$file" -colorspace Gray "$file"; done for file in /usr/share/themes/Mint-Y-Dark/gtk-3.0/assets/*.png; do convert "$file" -colorspace Gray "$file"; done Edit the /usr/share/themes/Mint-Y-Dark/gtk-2.0/gtkrc ...

Updated 03-Aug-2025 Well, it turns out, there is no such thing, per se, as an IPA Keyboard Layout, at least not in the sense that there are keyboard layouts for various languages and layout styles (e.g., English, Dvorak, etc.).

Updated 03-Aug-2025 Note: since Debian has Cinnamon built-in as a desktop choice on install, and since the rest of Mint is Ubuntu or Debian (LMDE), it seems a bit nonsensical to go Mint when I can go Debian +Cinnamon.
