Install Multiple Java Versions on macOS High Sierra

Install Homebrew Cask

On Mac, Homebrew is the de-facto package manager, and Homebrew Cask is the app manager. I’m going to use Cask to install Java 7 and 8.

Install Homebrew Cask first if you haven’t:

brew update
brew tap caskroom/cask

Rich Hickey on becoming a better developer

Rich Hickey • 3 years ago

Sorry, I have to disagree with the entire premise here.

A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.

Mastery comes from a combination of at least several of the following:

mkdir -p /usr/local/etc/nginx/sites-{enabled,available}
cd /usr/local/etc/nginx/sites-enabled
ln -s ../sites-available/default.conf
ln -s ../sites-available/default-ssl.conf

File locations:

• nginx.conf to /usr/local/etc/nginx/
• default.conf and default-ssl.conf to /usr/local/etc/nginx/sites-available
• homebrew.mxcl.nginx.plist to /Library/LaunchDaemons/
