PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

oanhnn

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

1. Generate ssh key pairs for accounts and add them to GitHub accounts.

Swagger Setup for Embedded Jetty Server

In setting up a Jetty server with Jersey servlets, you may choose to use an embedded Jetty server setup. (See here for how to setup an embedded Jetty server). In this gist, we'll go through how to setup Swagger for this setup. I am using Swagger 1.5, Maven 3.3.3, Jersey 1.8, and Jetty 7.3. Make sure you add all dependencies to your pom.xml.

In the Swagger Core setup, the current official recommendations involve an Application class, or a web.xml, neither of which are used in an embedded Jetty server setup. To add Swagger to your embedded Jetty Server, you must do 3 things:

1. Add the package scanning packages to your servlets which will serve your REST API.
2. Add the Swagger package scanning servlet.
3. P
