QUESTION
Here is my underdeveloped pygame ping-pong game, but my sprites(player&opponent) ain't moving, on giving a keyboard input. And when I quit the program, it yells an error pygame.error: video system not initialized. My pygame is the latest 1.9.6 version with all the files up-to-daee. However, I am certain that pygame.display is generating this error, but I even tried pygame.display.init() and that too didn't worked :(

QUESTION
(novice in coding, i just follow tutorials and try to understand and learn at the same time) I recently wanted to code my own Discord bot but i had an issue with the event handler part so i tried another method but now i have another issue.
Instead of responding "pong" to "p!ping", it says :
client.commands.get('ping').execute(message, args); ^
TypeError: Cannot read property 'get' of undefined
at Object.execute (.../events/message.js:18:23)
at Client.
I also tried to replace

client.commands.cache.get('ping').execute(message, args); or even client.commands.find('ping').execute(message, args); but it says "TypeError: Cannot read property 'get' of undefined - Discord bot" or even

if (command === 'ping'){ with
if (command === `${prefix}ping`){
and it works, i think i just have to do that with all the commands. If you have an easier solution please feel free to share it or if you found the issue with the code please tell me. (because before it worked without this modification),
thank you

QUESTION
I am working on setting up a three node Docker swarm for a web application I support. Initially, we have Traefik setup as a reverse proxy. Traefik and the web app both run on the same web server and the web server is in a single node docker swarm. We are trying to add two additional nodes for application stability.
At the moment, I'm simply trying to understand Traefik load balancing along with Docker Swarm. I am deploying a Traefik v1.7 stack and including the whoami application. The docker-compose file for this first past looks like:

My script works as intended as far as I can tell, however when I try to exit it using ctrl+c it simply doesnt stop.
