Funny drawing app project

Usage

npm start

Start Rust drawing apps:

cargo run --release

Sync new code to drawing clients:

./sync.sh

Some Notes

Starting Apps on Login

There are two systemctl services which allow the computer to run the apps on startup. These are located in /etc/systemd/system/npm-start.service and /etc/systemd/system/python-start.service.

The npm-start services runs the server.sh bash script, which simply runs the backend server, while the python-start services starts the Python monitor mapping script in start.py. If you have any issues, check the logs like so:

journalctl -u npm-start -b # or python-start

Disabling Touch Gestures

A common issue with the drawing app setup is that swiping with 3 fingers will result in the app panel opening and an exploded view of the open apps on the computer, similar to pressing the Super key on the computer. I installed a gnome-extension to disable these gestures.

This didn't actually work, for reasons untold. This implementation is left as an exercise to future years. (In particular, it seemed to disable touch events).
