Scala for Python Programmers, examples
/*
Notes:
Despite Scala's appearances, it is, in fact, a Statically Typed language.
It has just eliminated a great deal of the "type vomit" people are used
to seeing in Statically Typed languages (e.g. C, C++, Java). It often
can infer the type on its own. It also combines functional and
object-oriented programming paradigms in a fashion that feels similar
to Python.

How to proxy web apps using nginx?

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

PostgreSQL command line cheatsheet

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)
