Introduction

What is Docker?

Docker is a set of tools that allow us to easily run containers and containerised apps. Why use Docker and these so called "containers"?

Well, containers are extremely useful as they are very lightweight and have minimal overheads. We can package an app along with just its dependencies and can isolate this into a container. These containers can then be run on absolutely any platform with a Docker engine. It has other benefits too like minimal storage requirements, resource isolation, security, namespacing (isolating resources per process or a group of processes), availability and elasticity in the cloud, and much more!

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

	# this is a testing file for intal (integer of arbitrary length) in C, to be used with the python file
	# Steps to use
	# 1. Compile with the main file (which is here - https://gist.github.com/Samyak2/d0c2552b11581f59091f9f377bbc65f0)
	# 1.1 Make sure the executable is named `intal` (using `-o intal` during compiling)
	# 2. Make sure python version is >=3.6 and scipy is installed
	# 3. Run this script
	# excuse the bad code, it was only intended to work
	# Here is another version to test the time complexity - https://gist.github.com/Samyak2/a2975ec738e76dd7ead1147db3c0ef93
