Mac OS X 10.11 El Capitan Setup

Mac OS X 10.11 El Capitan

Custom recipe to get OS X 10.11 El Capitan running from scratch, setup applications and developer environment. This is very similar (and currently mostly the same) as my 10.10 Yosemite setup recipe (as found on this gist https://gist.github.com/kevinelliott/0726211d17020a6abc1f). Note that I expect this to change significantly as I install El Capitan several times.

I use this gist to keep track of the important software and steps required to have a functioning system after a semi-annual fresh install. On average, I reinstall each computer from scratch every 6 months, and I do not perform upgrades between distros.

This keeps the system performing at top speeds, clean of trojans, spyware, and ensures that I maintain good organizational practices for my content and backups. I highly recommend this.

You are encouraged to fork this and modify it to your heart's content to match your own needs.

Install Apache with Homebrew

Install Apache with Homebrew

Installing Apache

# Start by stopping the built-in Apache, if it's running, and prevent it from starting on boot.
# This is one of very few times you'll need to use sudo:
sudo launchctl unload /System/Library/LaunchDaemons/org.apache.httpd.plist 2>/dev/null

# We need to tap homebrew-dupes because "homebrew-apache/httpd22" relies on "homebrew-dupes/zlib"

and install Apache 2.2 with the event MPM, and we'll use Homebrew's OpenSSL library

Angular vs Backbone vs React vs Ember notes

Note: these are pretty rough notes I made for my team on the fly as I was reading through some pages. Some could be mildly inaccurate but hopefully not terribly so. I might resort to convenient fiction & simplification sometimes.

My top contenders, mostly based on popularity / community etc:

  • Angular
  • Backbone
  • React
  • Ember

Mostly about MVC (or derivatives, MVP / MVVM).
