Signing git commits on github using keybase.io gpg key

Probably one of the easiest things you'll ever do with gpg

Install Keybase: https://keybase.io/download and Ensure the keybase cli is in your PATH

First get the public key

keybase pgp export | gpg --import

Next get the private key

Upgrade PostgreSQL 9.6.5 to 10.0 using Homebrew (macOS)
After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work.
The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0."
Database files have to be updated before starting the server, here are the steps that had to be followed:
# need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default
brew unlink postgresql
brew install postgresql@9.6
brew unlink postgresql@9.6
brew link postgresql

Responsive images helper using srcset in Rails
module ImagesHelper
# Acts as a thin wrapper for image_tag and generates an srcset attribute for regular image tags
# for usage with responsive images polyfills like picturefill.js, supports asset pipeline path helpers.
#
# image_set_tag 'pic_1980.jpg', { 'pic_640.jpg' => '640w', 'pic_1024.jpg' => '1024w', 'pic_1980.jpg' => '1980w' }, sizes: '100vw', class: 'my-image'
#
# => <img src="/assets/ants_1980.jpg" srcset="/assets/pic_640.jpg 640w, /assets/pic_1024.jpg 1024w, /assets/pic_1980.jpg 1980w" sizes="100vw" class="my-image">

def image_set_tag(source, srcset = {}, options = {})
srcset = srcset.map { |src, size| "#{path_to_image(src)} #{size}" }.join(', ')

Super simple way to randomly load new images on refresh via Jquery and DOM injection. Great for banners.
