Need

Convert .mov/.MP4 to .gif

Reason

As a developer, I feel better to upload a short video when I create the pull request to show other viewers what I did in this PR. I tried .mov format directly got after finishing recording screen using Quicktime, however, gif offers preview in most web pages, and has smaller file size.

This is not limited to developer, anyone has this need can use this method to convert the files.

Requirements

python 3.6, postgres, pip install aiohttp uvloop ujson asyncpg sanic

aiohttp & uvloop

➤ wrk -d 10 -c 100 -t 12 --timeout 8 http://localhost:8000  # aiohttp
Running 10s test @ http://localhost:8000

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

	# How to monitor a secure external etcd service with Prometheus Operator
	This guide will help you monitor an external etcd cluster. When the etcd is not hosted inside Kubernetes.
	This is often the case with the Kubernetes setup. This has been tested with kube-aws but same principals will apply to other tools.

	# Step 1 - Make the etcd certificates available to Prometheus pod
	Prometheus Operator (and Prometheus) allow us to specify a tlsConfig. This is required as most likely your etcd metrics end points is secure.

	## a - Create the secrets in the namespace
	Prometheus Operator allows us to mount secrets in the pod. By loading the secrets as files, they can be made available inside the Prometheus pod.
