Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

install virtualbox-guest-dkms for ubuntu 64bit (解决分辨率问题)

sudo apt-get install virtualbox-guest-dkms
sudo reboot

git clone https://gist.github.com/dd6f95398c1bdc9f1038.git vault
cd vault
docker-compose up -d
export VAULT_ADDR=http://192.168.99.100:8200

Initializing a vault:

Scala: Type Families, Sealed Traits, and Exhaustive Pattern Matching

By: Matt Barackman

What is a Type Family?

A collection of objects or case classes that share a sealed trait.

In the example below, the type family would be a collection of traffic light colors with Red, Yellow, and Green as member objects.
