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)

String Comparison

In this gist, i will try to explain you what is the main differences between known string comparison techniques and where to use them.

Explanation of methods

==

This is the main equality operator in Java. To summarize it, this method compares the left and right hands references to eachother and returns boolean. This means this operator returns true only if left and right variable both point at the same Object in the memory. As in most of the class comparisons, this operators is discouraged to use if you're not really intented to check if two variables point to same object.

# GitLab uses docker in the background, so we need to specify the 
# image versions. This is useful because we're freely to use
# multiple node versions to work with it. They come from the docker
# repo.
# Uses NodeJS V 9.4.0
image: node:9.4.0

# And to cache them as well.

VirtualBox

• https://www.docker.com/toolbox
• docker-machine create --driver virtualbox dev
• docker-machine env dev (add values to ~/.zshrc)
  • e.g. echo eval "$(docker-machine env dev)" >> ~/.zshrc
• docker-machine ls
• docker ps (might need to re-source .zshrc file; e.g. . ~/.zshrc)
• docker run hello-world
• docker-machine ip dev
