🎁 First person to comment down below what TV Show the exercise files were based off of and their favorite characters gets a free cybersecurity book of their choice below a certain price range because I am kinda a broke college student.
🍪 Count the number of times I say "Now" throughout the entire series and you get a free cookie... 😋

Hey Grant.
I'm about to start my course in Certificate 4 Cyber Security (Australia, Melbourne) on Oct 5th. I've heard from various sources that ANY job in I.T now requires some basic knowledge or understanding of Linux.
I will continue to learn from you and your content as I begin my journey for the next 4 years into this mind-blowing world of I.T.
I've spent the last 2 years in a Trade background so this field is foreign to me, but growing up in a technology driven world, I've always had this itch to learn and understand more to it.

I like learning from these young guys. In 45 and have my CCNA and JNCIA and wanting to get into Cyber security but want to learn Linux first.

[zigginzag]

I learned Linux when the only computer I had access to was a 2008 Dell Inspiron (I think) with a whopping 3GB of RAM and a busted hard drive. I managed to upload Slitaz to a 4GB USB (on a friends computer) and ran the live version learning what I was doing by reading the small print on my phone and dealing with a lot of frustration.
My point is, take this gift Grant is giving you and cherish it!

[majamoore]

Thanks for sharing! I am self-teaching myself cybersecurity. I really appreciate persons like yourself for sharing knowledge and resources like this.

[mehwishmishu]

We learnt linux in the very first semester of cyber security and digital infrastructure... its fun though!

42:55 you should try to explain the binary system there, it can be hard to memorize the numerical permissions without knowing the meaning behind them

[lunaticironclad]

God damn, I thank you and appreciate all of the work you put in to pass down your knowledge, i started cyber security and that kinda thing self learning ever since I was 11 and these videos are gold mines and I will forever be thankful, thanks for helping another cyber fella!
