Overview

While I was trying to solve the Rubix Cube 2x2 all by myself, found it really challenging. Then bit of help from Google and Youtube, I got the working formula and wanted to share it with everyone.

Solve for 3 colors

Prerequisites

• Make sure you have 3 whites together.

I recently was trying to boot my old linux mint laptop and got a error message that my /boot was full. I did google for the solution and finally found a way to claim the space by removing old and unused space by just using the below script.

#!/usr/bin/env bash

OLDCONF=$(dpkg -l|grep "^rc"|awk '{print $2}')
CURKERNEL=$(uname -r|sed 's/-*[a-z]//g'|sed 's/-386//g')
LINUXPKG="linux-(image|headers|ubuntu-modules|restricted-modules)"
METALINUXPKG="linux-(image|headers|restricted-modules)-(generic|i386|server|common|rt|xen)"
OLDKERNELS=$(dpkg -l|awk '{print $2}'|grep -E $LINUXPKG |grep -vE $METALINUXPKG|grep -v $CURKERNEL)

#!/bin/bash
openssl genrsa -out privkey.pem 2048
openssl rsa -pubout -in privkey.pem -out pubkey.pem

SIGNING_KEY=$(cat privkey.pem)
VERIFICATION_KEY=$(cat pubkey.pem)

JWT_SIGNING_KEYS=$(cat <<EOF

Run the following OpenSSL command to generate your private key and public certificate. Answer the questions and enter the Common Name when prompted.

openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem

Review the created certificate:

openssl x509 -text -noout -in certificate.pem

Combine your key and certificate in a PKCS#12 (P12) bundle:

Step 1: Remove the remote
