Experiment to render the weather forecast as fast as possible. Goal is sub 100ms. ~40 milliseconds if you're in NYC.

Set-up

python3 -m venv venv && source venv/bin/activate && pip3 install -r requirements.txt && FLASK_APP=app.py FLASK_DEBUG=1 python -m flask run --port=5001

source venv/bin/activate
sudo -H pip3 install -r requirements.txt
sudo FLASK_APP=app.py python3 -m flask run --port=5001

Ctrl a p to detatch from the screen

Production reset

(To find python processes:)
ps -ef | grep python
sudo kill -9 23826
("23826" is whatever the number is returned that you want to kill)
screen
sudo git pull
sudo python3 -m venv venv
source venv/bin/activate
sudo -H pip3 install -r requirements.txt
