We'll cover the basics of implenting a Command Line Interface using Clap. We'll explore how to use derive to provide mulitple functions for an application to run. We'll design a basic software package that will launch a Rocket.rs service, as well as a command line interface that will insert information into a (PostgreSQL)[https://hub.docker.com/_/postgres] which will in turn be rendered by a JSON API we've built.

By far, my favorite RDBMS is PostgreSQL. Having worked with MySQL, MSSQL, Cassandra, Redis and more; the versatility of PostgreSQL continues to inspire me to write better and more complex SQL. I have a piece of software that reaches out to various news websites following best practices for crawling. Scraping content using provided by the sitemap.xml and following the rules set forth by the robots.txt file. The content of these sites can be anything, but the general approach is to collect as much news as possible to see if I can develop a series of heuristics to provide as technical indicators.
