## input_pattern_attribute.html
<!--
  some types of input tags in HTML have the 'pattern attribute' available

underscores and numbers. Also, the nickname must have legnth between 5 - 15 chars. I would tip like this: [a-zA-Z1-9_]{5,15}
-->

## uuid.sql
/*
  UUID is used as PRIMARY or UNIQUE KEY in our table's rows. Different of sequencial primary key, that starts from 1 and
 are incremented 1 by 1, UUID is a hexadecimal random value that is generated automatically by the RDBMS.
  How to explain the pros and cons about UUID Use is not the goal here, I gonna just put how to use and convert the value
 from text to byte and vice-versa.

  If u wanna read and learn what is and the pros\cons about UUID, check this MySQL's Post:
