Self-Signed cert

Linux

1. Copy or SFTP certificate to machine
2. Go to /usr/local/share/ca-certificates/
3. Create a new folder, i.e. "sudo mkdir my-cert"
4. Copy the .crt file into the my-cert folder
5. Make sure the permissions are OK (755 for the folder, 644 for the file)
6. Run sudo update-ca-certificates

Protractor API

http://angular.github.io/protractor/#/api

Note: Most commands return promises, so you only resolve their values through using jasmine expect API or using .then(function()) structure

Based on this post: https://spagettikoodi.wordpress.com/2015/01/14/angular-testing-cheat-sheet/ by @crystoll

Control browser

browser.get('yoururl'); // Load address, can also use '#yourpage'

Edit — February 2019

This gist had a far larger impact than I imagined it would, and apparently people are still finding it, so a quick update:

• TC39 is currently moving forward with a slightly different version of TLA, referred to as 'variant B', in which a module with TLA doesn't block sibling execution. This vastly reduces the danger of parallelizable work happening in serial and thereby delaying startup, which was the concern that motivated me to write this gist
• In the wild, we're seeing (async main(){...}()) as a substitute for TLA. This completely eliminates the blocking problem (yay!) but it's less powerful, and harder to statically analyse (boo). In other words the lack of TLA is causing real problems
• Therefore, a version of TLA that solves the original issue is a valuable addition to the language, and I'm in full support of the current proposal, which you can read here.

I'll leave the rest of this document unedited, for archaeological
