Poor's man, Stress Tester

Here's a simplistic stress tester that bursts a given service multiple times in parallel.

Disclaimer: This script was designed to be a stress test tool and must be used with extreme care. Use it at your own discretion but warned that the author won't be responsible for any damage it might cause your targetted service. Therefore, be conservative with the numbers or you might put your services down.

How to install

Copy the below script into your Mac or Linux machine and save it as deny-the-service.sh. (Yeah, you might not have the tools available on your Windows, but you can give it a try if you want.)

Como te admiro por ser esse rio de paciência, cuidando deles como se nada

Useful Git Aliases

Meta-Programming Challenge

This is an experiment to practice Meta-Programming skills in JavaScript.

Acceptance Criteria

Create a generic Repository implementation (from the Repository Pattern)
It should be able to 'create', 'update' or 'delete' objects from a MySQL database
It should not rely on any other parameter aside of the persisted object itself (as an ORM might do).
