the kernel is also very fun to accidentally brick! fixing your system for 5 hours a day is an enjoyable hobby and has no significant consequences on my school and work life at all!

yup

@@pilot8720 I regularly create a system image and store it on a USB in case something like that happens. Kernel breaks? Just restore a previous version of my system, ez.

Gosh, seriously thank you! I have tried to understand for seriously a couple years now and I couldn't wrap my mind around what a kernel actually is and kept reading conflicting statements. This was clear, concise, and just clicked. Thanks

@Denshi 7 месяцев назад

Thank you! I made this video especially because I was so frustrated at how I couldn't understand kernels clearly in the beginning. After reading into it and focusing on my understanding, it finally clicked, and I made this video.

Kernel compilation video and gentoo stuff ? sign me up :eyes: This channel is too underated, what i love the most are the quick explainations, the video just seamlessly flows together, unlike some more precise and "professional" content. Keep it up :)

@Cuqerr 3 года назад

Nice video! I am looking forward to seeing the kernel compilation and Gentoo video!

@noel_curray Месяц назад

thank you for explaining it in a way I understand. I like the explanation about the monolithic side of the kernel and the modprobe pcspkr.

IDK how it is at your place but ATMs in germany do usually use Windows and it is quite common to see them bluescreen or in headless mode.

@FLMKane Год назад

Yeah those are older ATMs running Windows CE usually. Some ancient ones I saw in a strip club looked like they ran os2

@Donnirononon Год назад

@@FLMKane Always an experience when you need some physical money, you drive to the house bank, go to the ATM and you are greetet with a System32 style input. We had another bank in the next city but guess what ATM was usually broken too.

@mikhael00777 6 месяцев назад

Was a good basic explanation, but to do the actual programming, this crowd will need to learn how to program in C to fully understand the how. Loading and unloading kernel modules is what most standard Linux system administrators will be required to understand and know how to do.

I want to compile my own kernel I'm interested since I was 17 (2018) can you provide any articles or links which I can use to learn

@CornelianEmotions 2 года назад

Linux From Scratch (LFS) and Gentoo are very nice projects for thar. With Gentoo you can get to create your own custom kernel, compile it, and use it.

@pw.70 Месяц назад

You've got a bit of a weird video going on here - you're addressing the audience as if they were developers, but most developers would know the rudimentaries of an OS. I came here, really to see what the differences are between it and other OSs . Still interesting to me, but you might lose non-techies along the way.

Linux is kernel into itself so u dont have to place ”Kernel” after ”Linux”

@zielony1212 2 года назад

@Watcher No one said newbies need to understand this.

@zielony1212 2 года назад

@Watcher No. I do not care about them. If they want to use Linux, they will use it without struggling with "Linux", "GNU" or "GNU/Linux". I do not care too much about random people.

@zielony1212 2 года назад

@Watcher I care about myself and my family, not about Linux community.

@leg1187 Год назад

You kinda do. There are multiple Kernels out their in the world.

@bekua_ Год назад

"The reason linux is so fast, is since it is free and open-source." Really? I am okay with simplification but this is misleading.

@Denshi Год назад

I agree, this is an over-simplification. Put simply, Linux as a kernel is more modern and more frequently updated piece of software compared to something like the NT kernel used in Windows. It also doesn't have as much legacy baggage, and it's open to improvements in both speed and compatibility to the public.

@mantacid1221 11 месяцев назад

Plus, kernel devs have a mindset of “if a kernel change breaks someone’s software, then it’s our fault.” What you get is something that’s compatible with older hardware, and this makes its performance very good.

@LeMustache 7 месяцев назад

@@mantacid1221I'm sorry but that comment is silly does not make any sense. Strong backward compatibility, which is definitely not exclusive to Linux, has nothing to do with good performance. It can be quite the contrary in fact, since you can be blocked from making changes that could improve performance in fear of making a breaking change.
