Discord Tips

• To include some code in your post, surround the code in single backticks (`) for inline code, or triple backticks for a block of code.
• You can add an optional language marker to get syntax highlighting for that language. Common markers are py, c, and sh.

`​`​`py
# Check for equals.
if a == b:
    print("Match")
`​`​`
becomes:
# Check for equals.
if a == b:
    print("Match")

I'm writing this on my temporary journal at FrayedGenes,com because I'm in the middle of upgrading the wiki installation on my regular journaling site. It's taking a long time to finish, which makes me worried that there's something wrong, but so far at least it isn't throwing any more errors, now that I have the upgraded EmbedVideo extension files loaded. It took some time to get that figured out, since I didn't realize the current lealease directory had the files in a normal compressed .gz package instead of a .git repo. However, because I thought it was a .git thing, now I know how to download one of those using the CLI, and a whole lot more about Git and GitHub than I ever thought I needed to know. I still need to finish the course, but I'm pretty sure I know most of what I need now, since I'm not really using it for version control. I will complete it, though, since it's good information and a useful skill.

Another thing I accomplished today that did employ the knowledge of how to download a .git repo, was updating the driver for the CH340 board I bought to use with the Sparkfun Edge board for doing the exercises in the TinyML book. In the process I also used makefile for the first time. The step-by-step instructions for updating the drivers were on the Sparkfun website so I didn't really need to understand what I was doing, but I intend to do another Linux basics course to learn more about that utility, since it's an important one. I've been limited in what I can do without knowing how to use it. I found a class on Coursera that might cover that, but I'll keep looking to see if I can find something more specific.
