Linux! Open Source! Nerdy Toys!
You're probably here because you ran across one of my training videos. I try really hard to stick to what I know, and teach Linux stuff and technology adjacent stuff. But... sometimes I can't help myself and I post videos about whatever super nerdy thing I'm doing or playing with. But if you like Linux, you might like the other nerdy stuff that occasionally distracts me. You'll only know if you subscribe!
I do lots of others stuff too. I even have a web comic! If you want to see my other stuff, you can find me here:

Linux Loops: FOR, WHILE, and UNTIL (Linux+ Objective 3.1.2)
Loops are SO important for a Linux user, because it makes the commandline work FOR you instead of against you.
This video covers WHILE, UNTIL, and FOR loops. The syntax, the methods you can use for looping, and even why you might want to use the various loop constructs. Plus, it's just fun to learn about BASH scripting!
The CompTIA Linux+ objectives are available here: snar.co/plusobjectives

I have tried everything to get my reverse ssh to work. I give up. Are you available to write a powershell script for me ? Or give me a detailed explanation of how to set this up for me? If so how much would you charge me?
You give me bill nye vibes! Great job teaching!
I purchased one of the massager guns you referred to and the battery did not last long so I purchased another better quality one. I charged the newest one before using it and then plugged the old one in to charge. About 15 minutes later the old one exploded and caught fire as the battery blew up not once but twice. The charger for the new one was 24v and the old one was 12v. It was the same type of device, looked very similar and had the same barrel connector. I now suggest throwing away all you old transformers and only using the one that came with the original device !
bought a 12v dc fridge for my drinks. currently running it with a GaN usb-c powersupply. saves money. usb-c and GaN hopefully going to replace a lot of these old wallwarts
Thanks. I was wondering about supply that matched all the things but voltage. It was 9 volt and device was 6 volt. Your video helped me. Thank you! 😀
hm I did the secretdrive UUID="####" - in /etc/fstab and now my VMbox is not able to boot up my kali linux system anymore.
Wow! The dynamic port forwarding is already cool, but this sshuttle seems even better! I wonder though, this program is needed to be installed locally only? Nothing needs to be setup remotely on ssh servers? Thanks for the video!
Did not know how to sign in on interacting window, seemed to be working fine up to that. Help
I did grsecurity rbac like 20 years ago, and this apparmour is way easier and actually looks useable
That was an awesome overview
the intense eye contact and the demanding that I am kind is distracting me and reminding me that I need therapy.
appreciated
Thanks for creating this video series Shawn! As a Network Engineer looking to upskill and maybe make some career changes I am loving your videos. I do have one question, what is your deciding choice for using rocky for the class over fedora or centos, or even rhel developer option?
You pet that dog right now.
Great video! I leaned a ton! Thank you, God Bless you!
@14.16 Imagine your friend has a car that only they can drive because they own it (analogous to file ownership and permissions). However, your friend decides to set a special feature on their car (SUID) that allows you (and only you) to drive it as if you were the owner when you need to.
I'd like to thank you so much for your time and passion to teach. I used your playlist along other resources and I passed today - 750/800. I'd love to see you cover the next essentials certifications like security, web development and the new open source in the future.
Thank you for doing this!
Voltage and amperage is key
@10:45 we can use user : group instead of a . that will also works
I can't even enable SElinux :D Installed a fresh copy of Rocky Linux which came with policycoreutils preinstalled but sestatus showed disabled. There was no config file in /etc/selinux/, but I created one a filled with SELINUX=enforcing/permissive, restarted the system after every change, but still disabled. Uninstalled policycoreutils, restarted the os, installed it again (still no config) file, restarted but still disabled. Installed it on Ubuntu where it created the config file, change the SELINUX value to permissive/enforcing, restarted but it's still disabled.
Installed CentOS and it also doesn't have the config file and SElinux is disabled by default.
Found the issue. I was using containers and WSL and apparently SElinux won't work on those. I've just spinned up a linux VM and it's enabled by default.
day one of watching all of your Linux Videos <3
talking about feet right of the bat caught me so offgaurd
Love the livestreams! Will be sure to tune in next Sunday. Had the US Open (golf) this past weekend!
I tried to make to the live-stream, but i had a busy morning and ended up loosing track of the time. i enjoy the livestreams. and i don't think i will be able to make it next week. and i have noticed since you changed up the food that the squirrels are not going after them.
Yeah, I switched to safflower seeds, because squirrels don’t usually like them. But I ran out, so put regular bird seed in. The squirrels didn’t figure it out before I was able to get more safflower seeds. :)
I keep at least 1 type of each cable that I have at the house then throw away duplicate ones.
You're so right about "almost getting it" feeling. The only part I felt kinda confused was, since on ssh -R (remote one) you are going through 3 machines. The 127.0.0.1 in the second part confuses me on which machine that is for. I'll watch a few more times. Thanks for your videos!
You asked at the end what I"m drinking. I'm drinking a Gibraltar Latte. Great videos!
Thank you for your video. I'm trying to light up a led poll light and I never know which adapter goes with what device. Can I fry the light by putting the wrong one on. 🤷🏼♂️✌🏼️
So I'm going to get straight to it this is pretty much one of the best explanations of what a SSH remote server connection is. Ask somebody that is just starting in this journey which is cybersecurity, I can tell you that I have been looking on documentation to understand how this works but was not able to understand it until today thanks to this guy
Like a good neighbor stay over there. Love it XD
I am Bob, I testify that there is no password.
Hi Shawn, this week i past my Linux+ certification. I just wanna say thanks a lot for you're video's. It helpt me tremendously. The quality of you're video's are great. Thanks a lot and on to the next!
So much talking, so few valuable info
When I teach this concept, I share this tid-bit of logic.... Traffic flow is: FROM > TO <-> THROUGH You want traffic FROM somewhere to Forward TO somewhere THROUGH the host you log into Syntax: ssh -L/-R Local:Port:Remote:Port User@IP
I am a bit blocked here, how do you have so many block devices on one drives? Like I tried using a USB, but that's only 1 additional block device.
I'm learning so much from your videos, love the energy!
Thanks for the video, Shawn! It's been a year now since this video was made, and I wanted to share something I've observed. Fewer and fewer devices are being packaged with AC power supplies, even if the device has a USB-C "PD" port for additional power. Manufacturers are now just making these devices with USB ports, expecting you to use an existing adapter and a USB cable. Even old Apple adapters still work fine, even if you have to source a USB-A > USB-C charging cable.
"I Hate SELinux because it does what it was made to do" - corrected xD
Another Tip! Instead of "> file.sql" use "-r file.sql" that way you don't potentially lose characters due to conversion from utf8.
question: Regarding the recursive flag for the "rm" command, why is it lowercase 'r' but for the "ls" command it's a capital 'R'? Will those two commands work either way if you switch the casing on the R's?
The info on netcat actually came in use when i couldnt get scp to work with certs. This is a great work around if you at least have ssh working. Thanks
The first Brick is perfect for analog modular Synthesizers. 27V Power Supplys are mainly used by old Laptops. And if your polarity of your Barrel Jack Wallwart is wrong you can snap off the connector, reverse its polarity and solder it on again. Use shrinking tubes to seal the solderjoints and make them look professional
help i dont know how to use a web browser!
4:51 I got jump-scared!
Watching this thinking, after this latest news of Windows taking constant snapshots of your screen, maaaaaybe this could be the year 😂
Great video Shawn! I have dabbled with Linux for years, just so many cool things one can do, reading documentation and taking ownership of things. Permissions have always been a challenge but your explanation of sticky but has really helped me. I’ll be sure to check out more of your stuff. Thank you for sharing this info. I ran across it in my udemy course and this help explain things differently.
Nice videos mate thanks 👍👍😊😊
Passed my Linux+ on Friday. Kudos to you, my friend.
Awesome video dude 🤙🏼
