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)

Centralize the support libraries dependencies in gradle

Working with multi-modules project, it is very useful to centralize the dependencies, especially the support libraries.

A very good way is to separate gradle build files, defining something like:

root
  --gradleScript
 ----dependencies.gradle

Ansible

Understanding Ansible

Ansible is a powerful, simple, and easy to use tool for managing computers. It is most often used to update programs and configuration on dozens of servers at once, but the abstractions are the same whether you're managing one computer or a hundred. Ansible can even do "fun" things like change the desktop photo or backup personal files to the cloud. It can take a while to learn how to use Ansible because it has an extensive terminology, but once you understand the why and the how of Ansible, its power is readily apparent.

Ansible's power comes from its simplicity. Under the hood, Ansible is just a domain specific language (DSL) for a task runner for a secure shell (ssh). You write ansible yaml (.yml) files which describe the tasks which must run to turn plain old / virtualized / cloud computers into production ready server-beasts. These tasks, in turn, have easy to understand names like "copy", "file", "command", "ping", or "lineinfile". Each of these turns into shell comma
