Auto-deploying built products to gh-pages with GitHub Actions

This is a set up for projects which want to check in only their source files, but have their gh-pages branch automatically updated with some compiled output every time they push.

A file below this one contains the steps for doing this with Travis CI. However, these days I recommend GitHub Actions, for the following reasons:

• It is much easier and requires less steps, because you are already authenticated with GitHub, so you don't need to share secret keys across services like you do when coordinate Travis CI and GitHub.
• It is free, with no quotas.
• Anecdotally, builds are much faster with GitHub Actions than with Travis CI, especially in terms of time spent waiting for a builder.

Installing Python 2.7 on Centos 6.5

Centos 6.* comes with Python 2.6, but we can't just replace it with v2.7 because it's used by the OS internally (apparently) so you will need to install v2.7 (or 3.x, for that matter) along with it. Fortunately, CentOS made this quite painless with their Software Collections Repository

sudo yum update # update yum
sudo yum install centos-release-scl # install SCL 
sudo yum install python27 # install Python 2.7

To use it, you essentially spawn another shell (or script) while enabling the newer version of Python:

library('rgl'); library('magrittr')

cube <- function(x=0,y=0,z=0, bordered=TRUE, 
                 filled = TRUE, lwd=2, scale=1,
                 fillcol = gray(.95),
                 bordercol ='black', ...) {
  
  mycube <- cube3d()
  
  # Reduce size to unit

Install with Homebrew

brew install mysql

Set up launchctl to auto start mysql

$ ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents

/usr/local/opt/mysql/ is a symlink to /usr/local/Cellar/mysql/x.y.z (e.g., 5.6.16)
