I have installed Plan 9 on my Raspberry Pi. I am excited to start using it. I can't use Plan 9 yet because I need a new keyboard and mouse to use with my Pi. So, this evening I decided to peruse the online Plan 9 manual pages. I am excited and have been eagerly trying a few commands on my Mac to see what commands are also on my Mac.

I am continuing my foray into learning more about Linux and Unix. Over the last few days, I have learned about some shortcuts on the terminal that have made me think: "I wish I knew this existed long ago." (I'm not sure if the shortcuts I have learned are portable to every terminal, but they work on macOS and should work on Linux too.)

For the last few days, the server on which this website (and many others I run!) started acting strangely. Every so often, nginx would stop working and I'd have to restart the service manually. I had restarted nginx two or three times over the last few days so I knew something wasn't right. I spent some time this afternoon figuring out what was wrong. I found an issue with certbot renewals and nginx that, when resolved, fixed the errors I found in nginx and the /var/log/syslog file on my computer.
