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).

Some useful Postgres configuration changes for a dev machine:

log_connections = on

Actor - Fundamental unit of computation, a computation model - not just a form of concurrency

An Actor has three essential elements:

• 1 - Processing - you have to get something done
• 2 - Storage - you have to be able to remember things
• 3 - Communication
