thanks Jeff, I landed my current job thanks to the things I've learned from you for the past 3 years

[HassenTaidirt]

I don't have the money right now but I truly will support you mate once im able to we need more people like you.
Thanks for this wonderful content.

Thank you so much Jeff, that outro touched my heart! You are such a great soul, may lord always keep you in good health and wealth.

Hey Jeff. I just wanted to thank you for all of your hard work and high quality content. I just found your channel a couple days ago and you have become such an inspiration. I'm really looking forward to watching all your tutorials and hopefully being able to start to contribute more to the open source community myself. Thanks again!

Watching through these courses for the first time right now, it's absolutely eerie hearing the references to world events. It's really fascinating to look back and see, week-by-week, how sentiment and actions were changing, and how daily life was being affected. I'm sure it'll be even crazier to look back on some years from today, as well.

Anyways, thanks for this series! Learning a whole ton, and while a lot of it still goes over my head, I'm picking up a lot of tips and insight into how sysadmin type roles function in the real world, or at least how the tools used are implemented.

Hey Jeff, thanks for putting this series together - really appreciate how much you're giving out to the open community.
I'm currently retraining for a new career in the computer networking industry (ccna to begin with) and automation is rapidly becoming
a hot requirement, so this series is perfect.
Ansible is very cool 😃
Very happy to have purchased the ebook (physical purchase to follow) and be following along to this.
Keep up the great work.

Many thanks again!

Thank you for this video series. I used to tell my interns and soldiers to start with the following basic computer troubleshooting technique:
1. Is it plugged in?
2. Is it turned on?
3. Does it know who it is? (dns)
4. Does it know what time it is? (ntp)

Thank you. I really like your work. I found you because of Ansible solr setup, and I don't know much about ansible. So, was going through the weeds of things and stumbled upon you. haha. This is great. :D

Running through these, and using an old HP DL380 G6 server with 24G ram, 24 CPU and 3 TB HD with RHEL8 as the base OS, and doing it all via SSH. Built all 3 servers in half the time of the MAC, and best part, the server was free, and I only added 6 600GB HD@ $40 each. Awesome lab server!

I am also from the south of The Netherlands and I didn't expect that your family also would be. Do you know what area? Maybe we used to be neighbors at some point😂. But anyway I am maybe a bit late for this but thanks for these tutorials. I am slowly building a bigger home lab and I wanted an easier way to manage all my servers. So these tutorials help me out a lot. Thanks for that!

[laurensdehaan]

Thanks a bunch for doing these videos, Jeff. I'm a total noob at this but I can see it's REALLY going to be beneficial for me.

I hope you and yours have made it through relatively unscathed, and continue to do so. Take care.

[nyanRETARD]

Oh my got... I watched just until you ran that first hostname command and I got the error. Then I had to debug it and continued watching. Now 30 seconds later you tell me about the error :D and I am just like "yeah :D" great video! love it

[Lehi]

I'll be waiting until I can buy it again. :) You deserve the money, sir. :)

[williambell]

Ordered both your ansible books.. great job on these videos.. Hope you are doing well

[mohibnkhan]

I liked your work and I purchased the book. Keep up the good work!!!

[TAICHISCO]

Thanks Jeff, can't wait for the Episode 3.

[Badgr]

Oh wow! I didn't know your roots are from the Netherlands. I'm a Dutchman too, and I've been following you for a long time! Let's meet up if you're in for a coffee with a fellow geek.

[testlan]

Great job Jeff, I think the best cut could be the videos and cut into the details more in the book, and then docs online. very helpful. thanks.

[Brac]

Great idea Jeff. During this "stay at home" period, good time for a refresher!!. "Dallas Texas"
