I drop files I want to share in ~/public_html/files/ as I have a webserver running on my desktop with the firewall open to the local network. Might be tough for a noob to setup though. But on my phone the file shows up in /~christopher/files/ and I have trouble remembering how to type the tilde.

No toca los PopOS!

I'm pretty sure Android Studio has a search function for its menus.

In case you're on Archlinux, the thonny 4.1.4-1 package in chaotic-aur unofficial repo works for me.

For the ebook, install pandoc, then run this:

pandoc -f rst -t epub2 -o pkgsample.epub --metadata title="nedbat/pkgsample: A simple example of how to structure a Python project" --metadata author="Ned Batchelder" https://github.com/nedbat/pkgsample/raw/main/README.rst

On Debian, there is a package that displays system documentation including, if I remember correctly, man pages. I think I had to set up a local web server first.

On my computer,

ps -ef | grep Xorg

gives

root 642 632 0 06:09 tty7 00:03:26 /usr/lib/Xorg :0 -seat seat0 -auth /run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch

showing that the X server is running. I suspect that when you run the above ps command, that you will get no output, which shows that the X server is not running on your computer. In that case, you need to remove the lock that is preventing it from starting:

rm /tmp/.X0-lock
