All stable versions of the Linux kernel are numbered in the usual scheme, so major number DOT minor number, but they also have really strange codenames. Some distros tend to modify these kernels with additional patches, or features that haven't been added yet, which is why you can see some kernel versions with a "-ubuntu" at the end for example. Certain kernel versions are also marked as LTS, meaning Long Term support. These are versions that will be supported for much longer, up to 6 years. The Linux kernel project recently reduced that support window to 2 years. Since both the stable and LTS kernels ship with some non free firmware, there's the Kernel Libre project, which removes all of that, to only ship software and code that is completely free, as in freedom.. Next, we have the hardened kernel. It's not an "official" project per se, it's a kernel version that certain distros ship in their repos, like Arch Linux for example. It's the stable kernel, with an additional patch set applied to it to make it more resilient security-wise. Next, we have the realtime kernel. The goal is to reduce the latency between a task being assigned to the CPU, and its execution, and it's mainly meant for industrial applications, or for audio production. This, in turn, makes it less efficient for multi tasking, and it requires a lot more manual config to be efficient, and applications need to be specifically tailored to take advantage of this lower latency. The low latency kernel variants do the same thing, but at a lesser degree: it still lets you pre-empt CPU threads like the real time kernel, but it isn't as regular as the realtime kernel. The Android kernel is focused on supporting a specific category of devices, meaning that it has optimizations for these exact things. The Zen kernel applies a few fixes and improvements meant to have the best performance and experience for linux desktop users. It's also packaged as the Liquorix kernel for Ubuntu or Debian, and other distros, although Liquorix isn't exactly like the Zen kernel. Another version is the XanMod kernel, with sort of the same optimization as the Zen kernel, and a few more on top of that, with the same goal: improving the performance of Linux systems. Finally, we have the TKG kernels, and I'm saying kernels, because TKG isn't a specific Linux kernel you can download and use, it's more like a build system that lets you choose a few specific patches and compile your own kernel with that.

Just. Write. Something.

I hate that everything has defaulted to video these days.

They are a video creator first and foremost, not a writer for a blog or a magazine. It's like demanding a janitor to make and serve you a meal just because they work in a kitchen.

And then asking the janitor why they're a janitor instead of a cook. Like, if you don't like videos that's fine, but what is the point of commenting on one saying "god I hate videos."

It's especially funny that they said that everyone defaults to videos when, at least with Linux related stuff, thats definitely not the case. This guy is one of the few not terrible Linux content creators, there really aren't many Linux dedicated content creators to begin with, so what's the harm of this? Go read the arch wiki or a blog if that's what you prefer, but don't needlessly shit on a different format that others may prefer or enjoy.

Write some shit. I read faster than this moron talks. Alternatively I'll just not watch it?

Take like five seconds and figure out why marketing folks want videos to be the default and come back to talk with grown ups.

I fucking hate how stupid most people are. Our species is fucking doomed.

Since you seem like a much more reasonable human…

For many kinds of content, I also prefer text over video for exactly the reason you say—it takes less time to read. In particular, if a company can choose a medium, I wish they close text more often. So, there is a kernel of a reasonable point here.

All that said…

Beyond just the totally unacceptable tone, even the reasonable part of the comment is misplaced here.

This is not a company, it is a single guy. Projecting onto his videos your thoughts on the motivations of the “marketing” dept seems a bit silly.

Most importantly, this guy is a YouTube content creator. His job is to create videos for YouTube. People ( regular people ) ask him to do that. Insulting a YouTube content creator for creating content on YouTube is….well…I do not not want to start the name calling but let’s just say the insults hurled above apply more to the person making those comments than they do to the guy who made this video.

As for the bigger picture, there is room in the world for both text and video. Have you ever watched television? Do you constantly rant that everything on TV should have been a book or an article? What was more popular: Game of Thrones or a Song of Ice and Fire?

Despite your preference, video has more reach. This has been true since there has been video.

There is a lot of demand for YouTube videos. There is enough that regular people are able to make a small business for themselves out of creating YouTube content. That is what is happening here. Telling somebody to stop creating content that their fans enjoy and that funds the life that they want is pretty hostile and not very smart.

YouTube is entertainment. This is not content you have to consume. It is not about efficiency. It is not content that would have been produced some other way. If you do not like it, don’t consume it. Please though, do not waste everybody’s time complaining that it exists.

100%. I get where he's coming from, but making it seem like this is all a conspiracy by marketers is just ridiculous. If you prefer text, that's fine! But no one is going into the arch wiki and spamming about how they should ditch it for video. Different things appeal to different people, and writing off an entire format just because Google has enshittified YouTube is just dumb.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Rules

  • Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.
  • No misinformation
  • No NSFW content
  • No hate speech, bigotry, etc
