This is more complex than necessary.

GitHub webhooks for a URL by default only fire on repo pushes. There appears to be no way in the web UI to set up webhooks for other events. And so we go to the API. I prefer to do this type of thing with Hurl.

Jekyll & Liquid Cheatsheet

A list of the most common functionalities in Jekyll (Liquid). You can use Jekyll with GitHub Pages, just make sure you are using the proper version.

Running

Running a local server for testing purposes:

# 1) Create your private key (any password will do, we remove it below)

$ cd ~/.ssh
$ openssl genrsa -des3 -out server.orig.key 2048


# 2) Remove the password

$ openssl rsa -in server.orig.key -out server.key

Brew upgrade...

Run the usual brew update, and brew upgrade to get the latest 9.4 version of PostgreSQL.

After upgrading PG from 9.3 to 9.4 with brew, the server will not start as is. If you value your database contents, and configuration, pg_upgrade is here to migrate those.

Do not delete the old binaries at once: do not run brew cleanup, because you need 9.3 binaries to migrate.
