Esta é uma mini API em Go que fornece uma lista de feriados bancários nacionais no Brasil. A aplicação baixa os dados do site da FEBRABAN, os armazena em um banco de dados e os expõe através de um endpoint de API RESTful.
O projeto foi construído como um exercício para demonstrar a criação de uma API em Go, web scraping e interação com um banco de dados.
This skill outlines a methodology for determining the minimal systemd security configuration for any application by profiling its runtime behavior using strace.
Goal: Determine strictly which paths the application reads and writes to.
Run the application in the foreground (if possible) or attach to the process.

If you use git on the command-line, you'll eventually find yourself wanting aliases for your most commonly-used commands. It's incredibly useful to be able to explore your repos with only a few keystrokes that eventually get hardcoded into muscle memory.
Some people don't add aliases because they don't want to have to adjust to not having them on a remote server. Personally, I find that having aliases doesn't mean I that forget the underlying commands, and aliases provide such a massive improvement to my workflow that it would be crazy not to have them.
The simplest way to add an alias for a specific git command is to use a standard bash alias.
