pygame.display.update(); pygame.error: video system not initialized

Asked 2021-Jun-15 at 18:28

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 :(

TypeError: Cannot read property 'get' of undefined - Discord bot

Asked 2021-Jun-15 at 09:25

(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.get('ping').execute(message, args); with

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

I changed the

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),

The QueuePool constructor passes all keyword arguments to the Pool constructor. This constructor supports the dialect argument. So you should be able to add a dialect to your QueuePool call:

Support for _PIP_ADDITIONAL_REQUIREMENTS environment variable has not been released yet. It is only supported by the developer/unreleased version of the docker image. It is planned that this feature will be available in Airflow 2.1.1. For more information, see: Adding extra requirements for build and runtime of the PROD image.

For the older version, you should build a new image and set this image in the docker-compose.yaml. To do this, you need to follow a few steps.

Suppose fist node is master, when we reboot first node, failover happens and second node becomes master, until this point every thing is OK. But when fist node comes back it cannot sync with master and we saw that in its config no "masterauth" is set.
Here is the error log and Generated by CONFIG REWRITE config:

Traefik: Load Balance Across Three Node Docker Swarm

Asked 2021-Jun-13 at 03:53

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:

ANSWER

Answered 2021-Jun-13 at 03:53

Apparently Traefik can't drain the connections during update (maybe it doesn't have access to healthchecks and swarm info?).

To achieve a zero-downtime rolling update you should delegate the load-balancing to docker swarm itself:
