Not much update, been practicing lately like crazy. Bought additional reference material MRHCSA 7th Ed by Michael Jang (thanks Amazon prime shipping). Scheduled my exam in Feb, and also I got reimbursed by my company the whole 400USD cost of the exam (516cad). Only left thing to do is take the exam and pass it!

Intentionally Deleting FSTAB and Manually Recreating it for RedHat Enterprise Linux 7

One of the topics I’ve come across is mounting partitions automatically via FSTAB. fstab is a configuration text file that contains which partitions will be automatically mounted on startup.

TFSA for 2018

TFSA is Tax Free Savings Account, but do not let the name fool you. It is not a mere savings account. Most bank institutions package it like a savings account but it is more than that. It is an investment vehicle where the investments can earn tax free. Think of it like a passenger bus. A passenger bus can have multiple passengers - young kids, working adults, businessmen, stock traders, teachers, etc etc.
