Best Practices for Configuring Git CLI

1. Use your actual name. Your git history is valuable evidince of your skills and experience.
2. Use an email address that'll last. You may not be that proud of [email protected] in a few years.
3. If you don't know how to quit vi, change your default git editor
4. Create a global gitignore to make sure you don't commit needless, massive, or dangerous files to any repo.
5. Set colors (color.ui) to auto if possible. Git will automatically remove color info when piping into another output

Global Git Config

Canvas iFrame PostMessages

Here's the controls you have inside an iframe in Canvas based on the code here: https://github.com/instructure/canvas-lms/blob/master/public/javascripts/lti/messages.js#L74-L170

Updated w/ help from https://github.com/bagofarms after he realized my original information was incorrect. He found some readme docs from Bracken on the subject which opened things up: https://github.com/bracken/lti_messaging

Sending a post message to Canvas

const message = {

Need to test an aws cloudfront distribution before you change the DNS?

Let's imagine I'll be moving a domain (static.stuff.com) to cloudfront. I want to make sure that cloudfront is configured correctly before moving the dns for everyone. You can glue together a simple test with a couple commands locally

1. locate the cloudfront.net domain for your distribution under the AWS cloudfront general tab
2. nslookup xxxxxxxxx.cloudfront.net
3. Pick any of the ip addresses that domain resolves to (there will be several), lets assume 10.10.10.10 was one
4. Edit your /etc/hosts file and add a new line like : 10.10.10.10 static.stuff.com
