Setup OSX with a Clean Install

About once a year, my machine gets pretty sluggish and it's time to start fresh. Here's the process I use to update it with everything I need.

TODO: Add info about dotfiles set up and zsh (possible settings file?)

1. Start with a Fresh Install of OS X

Save all dotfiles to a repo for easy transfer
Back up all photos, music, apps, iTunes library, keychains, etc.

Examples of How to Derive a Signing Key for Signature Version 4 (AWS) for Google Apps Script

This is a sample script for "Examples of How to Derive a Signing Key for Signature Version 4" using Google Apps Script.

In order to use AWS SDKs, there are the sample scripts for the languages of Java, .NET (C#), Python, Ruby, JavaScript (Node.js). But the sample script of Google Apps Script is not prepared. I saw the question related to this at Stackoverflow. So I would like to also introduce the sample script here.

In the sample scripts, the input values are as follows.

key = 'wJalrXUtnFEMI/K7MDENG+bPxRfiCYEXAMPLEKEY'

If anyone is interested in setting up their system to automatically (or manually) sign their git commits with their GPG key, here are the steps:

Generate and add your key to GitHub
$ git config --global commit.gpgsign true ([OPTIONAL] every commit will now be signed)
$ git config --global user.signingkey ABCDEF01 (where ABCDEF01 is the fingerprint of the key to use)
$ git config --global alias.logs "log --show-signature" (now available as $ git logs)
$ git config --global alias.cis "commit -S" (optional if global signing is false)
$ echo "Some content" >> example.txt
$ git add example.txt
$ git cis -m "This commit is signed by a GPG key." (regular commit will work if global signing is enabled)

Methods of Signing with GPG

Last updated March 28, 2021

There are now two ways to approach this:

Using gpg and generating keys
Using Kryptonite by krypt.co

This Gist explains how to do this using gpg in a step-by-step fashion. Kryptonite is actually wickedly easy to use-but you will still need to follow the instructions
