[WINDOWS] How to enable auto-signing Git commits with GnuPG for programs that don't support it natively

This is a step-by-step guide on how to enable auto-signing Git commits with GPG for every applications that don't support it natively (eg. GitHub Desktop, Eclipse, Git Tower, ...)

Requirements

Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

kubectl get no

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.

How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

	package com.github.gist.it;

	import java.net.InetSocketAddress;
	import java.net.Socket;

	public class NetUtils {

	/**
	* check if a given server is listening on a given port in the limit of timeoutMs
	* @param serverHost server hostname (or ip)

	# The command finds the most recent tag that is reachable from a commit.
	# If the tag points to the commit, then only the tag is shown.
	# Otherwise, it suffixes the tag name with the number of additional commits on top of the tagged object
	# and the abbreviated object name of the most recent commit.
	git describe

	# With --abbrev set to 0, the command can be used to find the closest tagname without any suffix:
	git describe --abbrev=0

	# other examples

	// see build.gradle for imports
	import org.slf4j.Logger;
	import org.slf4j.LoggerFactory;
	import ch.qos.logback.classic.LoggerContext;
	import ch.qos.logback.core.util.StatusPrinter;
	...
	public abstract class Utilities {
	public static final Logger logger = LoggerFactory.getLogger( "AnyUniqueStringHere" );
	...
	public static void printLoggerState() {

	#!/bin/bash

	tmup ()
	{
	echo -n "Updating to latest tmux environment...";
	export IFS=",";
	for line in $(tmux showenv -t $(tmux display -p "#S") \| tr "\n" ",");
	do
	if [[ $line == -* ]]; then
	unset $(echo $line \| cut -c2-);
