                Ruby on Rails install after Mojave upgrade - getting Nokogiri and C compiler working
              
          
    I had to run the following cryptic commands to get my C compiler working in mac osx Mojave, after having everything working fine in a previous OS (Yosemite I think it was...)
This is an (somewhat) obvious step when upgrading osx:
xcode-select --install
I also had to do this, which I never would've known how to do without google and this post
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

  
## vim notes
vim

Vim is a text editor available on most unix systems, and can easily be installed via package managers if not installed.
 Great for working in the terminal.
Learning curve, but improves speed overtime.
Terminal based text editor is the tool of choice for most professional coders (vim or emacs).

My reasoning: why work with Atom, when you can work with Vim? Vim will always be there, always improving. Available on all systems, to all devs around the world (ssh into a server, use vim)

    SQL Notes

In this workshop, we will be learning and using SQL to access data in a relational database
Objectives:


Explain what a database is
Compare and contrast relational db vs NoSQL db
Write SQL commands to get data out of a database
Write SQL to put data into a database
