Norton Nanodragon999

This was tested on a ThinkPad P70 laptop with an Intel integrated graphics and an NVIDIA GPU:

lspci | egrep 'VGA|3D'
00:02.0 VGA compatible controller: Intel Corporation Device 191b (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GM204GLM [Quadro M3000M] (rev a1)

A reason to use the integrated graphics for display is if installing the NVIDIA drivers causes the display to stop working properly. In my case, Ubuntu would get stuck in a login loop after installing the NVIDIA drivers. This happened regardless if I installed the drivers from the "Additional Drivers" tab in "System Settings" or the ppa:graphics-drivers/ppa in the command-line.

Arbitrary Base Converter

Converts between arbitrary bases defined as alphabets (should work for any arbitrary alphabet not only for predefined ones):

const Alphabet = {
  BINARY:        '01',
  OCTAL:         '01234567',
  DECIMAL:       '0123456789',
  HEXA_DECIMAL:  '0123456789abcdef',
 ALPHA_LOWER: 'abcdefghijklmnopqrstuvwxyz',

Logging bash history to syslog

Overview

Bash history was a convenience feature to help a user recall previous commands and not intended to meet any security requirements.

The Linux audit system (or alternate kernel level audit OS facility) is a more robust way to ensure user and process log events are recorded.

Security issues with bash history files and `$BASH_COMMAND`

As professionals we look to always optimize our workload. Through better processes and shortcuts we can eliminate unnecessarily repetitive tasks. One of the tools I use quite often is the Command Line Interface (CLI) and Git, and this is an area that we can automate quite extensively through some really simple to learn BASH hacks.

We all have tasks that we do endlessly, and there are tasks that we do independently and don't realize that there is a definitive pattern that we can embrace, put them to use in a simpler function and alter the results on a per use basis. It is through years of doing things the hard way that I have found some simple tricks that makes my life much easier to maintain.

What is BASH anyway?

Let's get this out of the way quickly first. In short, it is a Unix shell and command language most common on Linux and macOS and recently has made it's way to Windows as well. It is the common interface for running simple commands or other applications such as GiT, Curl, Ack, etc ...
