Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

A curated list of AWS resources to prepare for the AWS Certifications

A curated list of awesome AWS resources you need to prepare for the all 5 AWS Certifications. This gist will include: open source repos, blogs & blogposts, ebooks, PDF, whitepapers, video courses, free lecture, slides, sample test and many other resources.

Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

###Array ####Definition:

Stores data elements based on an sequential, most commonly 0 based, index.
Based on tuples from set theory.

	#!/bin/bash
	# Usage:
	# ./update_git_repos.sh [parent_directory]
	# example usage:
	# ./update_git_repos.sh C:/GitProjects/ [MAKE SURE YOU USE / SLASHES]

	updateRepo() {
	local dir="$1"
	local original_dir="$2"
	cd $dir # switch to the git repo

	CI & CD:
	========
	2 core software development processes
	CI process of automating regular code commits followed by an automated build and test process designed to highlight intergration issues early.
	Additional tooling and functionality provided by Bamboo, CruiseControl, Jenkins, Go and TeamCity etc.
	workflow based
	CD takes the form of a workflow based process which accepts a tested software build payload from a CI server. Automates the deployment into a working QA, Pre-prod or Prod environment.
	AWS CodeDeploy and CodePipeline provide CI/CD services
	Elasticbeanstalk and CFN provide functionality which can be utilized by CI/CD servers.

	# N.B. The only tool missing here that is mentioned in the document is `zenmap`
	# purely because this image is intended to be run via a CLI and `zenmap` is a GUI
	# to `nmap` i.e. one can play around with the tools by running:
	#
	# $ docker build --name bite_size_networking:latest .
	# $ docker run --rm -d --name bsn_test bite_size_networking:latest
	# $ docker exec -it bsn_test bash

	# Alternatively, one can change the `ENTRYPOINT` to `["bash"]` and run:

	.SYNOPSIS
	Using AppName the script will find all variables for that project.
	It will then look at EnvironmentToCheck for variables that have
	been configured in other environments but not the one specified

	i.e.

	A variable named "Test" under the scope of a "Test" environment
	will be reported if a "Test" variable under the "Prod" environment

	#! python
	import shutil
	import sys
	import json
	from flatten_json import flatten

	# Author: Lalit kale
	# Tested with python version 3.6.6
	# This is the program through which build engineers can transform appsettings.json file
	# into Octopus Deploy tool's variables in the format required by my employer.
