Only one generation knows how to fix tech...

Lol, you lost me there. I've read up on the various RAID configurations. I've heard about CephFS. I don't know much about it, but I get the sense it's the new kid on the block.
I actually have a RAID question for you. I want to setup a little RAID array starting with 2 mirrored drives and add more drives later. But it seems there is no easy way to migrate RAID versions? Let's say I want to start with 2, then 3, than 4 drives as stuff fills up. I always want some level of redundancy. And I don't want to use any additional drives aside from the 2, 3, then 4 in the array. Is this possible? Either with RAID or with CephFS?
Funny you should mention that, because it's what got me thinking about Ceph in the first place. My other Proxmox node has a 2-drive mirrored ZFS pool, and I went to add a third drive to it and realized that I'd have to move all the data off and rebuild it from scratch, so I started looking for other solutions.
So yeah, I think Ceph can add to an array after-the-fact like that (in addition to the not-waste-capacity-of-random-assorted-disks thing), but I haven't figured it out enough yet to be sure.

Someone should rename the gens. I never know what people are refering to with the arbitrary names. Maybe gen a, b and c would work.

- The lowest level is transistors, which are electronic switches that have an on and off state. In other words, they are binary and can represent 0 and 1
- Those get combined into gates of two inputs. An “and” gate outputs 1 if both its inputs are 1. An “or” gate outputs 1 if either of its inputs are 1. And Xor gate outputs 1 if and only if one of its inputs is 1.
- A bunch of other complicated shit happens
- Boom assembly. Don’t try and read or write it, because it will make you wanna quit computers
- C comes into play. Designed to unfuck, assembly so you can actually write readable code. Just don’t forget to release your memory
- More complicated shit. Something about kernels and GNU. Userland vs kernel land? Idk
- ARM might be different since it can run process outside of userland and kernel I think? Something about secure compute/marketing BS
- Inside of user land, we have the web browser. This is there the cool shit happens.
- The browser runs JavaScript, CSS and HTML. JavaScript is a single threaded, but nonblocking language with an even loop and microtask queue.
- Inside of the browser we run React. React is a framework where UI is a function of state and the data flows in one direction. It can also be used to slam your CPU.
- Now that we’re into high level languages, it would only be fun if it looped back around to the beginning. So we invoke some C code that has been compiled to web assembly. Mmmm how efficient
Edit: I tried to do this all off the top of my head. After writing this, I think I meant user space vs kernel space. Idk if user land is a word
Transistors are only on and off switches when run in saturation. This is relevant to CPUs in the sense that the rising/falling edge and jitter affect the setup and hold times and thus the maximum clock rate. End pedantry.

I also totally was mixing up Ceph with ZFS. Linux tech mentions ZFS a lot. That’s the source of most of my RAID knowledge lol

Tldr; you got your feelings hurt over a meme
Gen x doesn't have feelings

lol. My dad’s a retired engineer and my mom was a computer programmer. Literal actual baby boomers.
I work in IT. Gen-X. Which you forgot because you’re bad.
My daughter just got her degree in Cybersecurity. Millennial.
tl;dr: STFU with this stupid inter-generational tribalism, it’s wrong and stupid.
You're all educated professionals. This meme is more about your average user.

They did use letters, but they started with Gen X, because X was a cool letter in the 80s. Gen Y was changed to millennials because that was the time period they grew up in. Then Gen Z, which is the end of the alphabet, so they restarted, but with the Greek alphabet for gen alpha.

Al Gore didn't need a smear campaign for his nonsense. I was there too, we were laughing our asses off at the shit he said.
"We don't think, as some people have argued, that Gore intended to claim he "invented" the Internet. Moreover, there is no question in our minds that while serving as Senator, Gore's initiatives had a significant and beneficial effect on the still-evolving Internet. The fact of the matter is that Gore was talking about and promoting the Internet long before most people were listening."

I don’t know about you, but I quit doing that soul crushing work as soon as I could something I really loved.

There's an active region between on and off where the current from the collector to emmiter is proportional to the base current. This can be used in other applications like amplifiers. But in digital applications that active region is the transition time between low and high states.
In order to obtain a deterministic outcome the rising edge must be predictable and it must stay at a logic level 1 for long enough to account for propagation delay. These considerations are known as setup and hold. The higher the frequency the clock runs, the tighter these constraints become.

To my fellow Gen X’ers…
Shhh!
Let someone else deal with the inept on the other end of the phone. Be happy we’re being ignored again.

Barry Leiner. He didn't like me dating his daughter because I wasn't Jewish. But man did he love his Celica. It wasn't fancy, but it was to him.
Barry Leiner wrote about how Gore helped get the Internet started:
"The Internet Society hosts a monograph called called "A Brief History of the Internet." (See http://www.isoc.org/internet-history/brief.html) The authors include some of the designers of the essential components of how the Internet works today: Barry M. Leiner, Vinton G. Cerf, David D. Clark, Robert E. Kahn, Leonard Kleinrock, Daniel C. Lynch, Jon Postel, Larry G. Roberts, and Stephen Wolff. The paper notes these key milestones in Internet history
Note that these authors of (and participants in) Internet history state clearly that as early as 1988, then-Senator Gore became involved in the goal of building a national research network. We'll examine his role in more detail later."

don't forget that the people that started naming the generations called themselves the "greatest generation"

Let's be fair, we millennial know how to fix stuff because stuff still can be fixed. We can glance back one generation away and learn about how stuff work back then, and also learn how to fix those stuff. Nowadays stuff aren't meant to be fixed, (late) gen z doesn't have thing to start tearing apart and learn about the inner working of stuff, because it's all glued/snapped together, with the culture being once broke just toss.

I've spent the last decade training Millennials just for that task.
I'll be over here screwing with the K8S cluster if you need me.
You seniors and your K8s I tell you whut

Yeah, this is more young X and old millennial. Xers born in the late 60s-early 70s and millennials born in the late 80s-90s don't know shit.
I've heard us (young Xs and old millennials) described as the
organOregon Trail generation. We grew up along side the tech so we understand it better than your average person from before or after.wrote last edited by [email protected]I'm not sure why people are down voting this. I agree 100%. The most techie people I have ever known are part of what you called "the Oregon Trail generation" (I love this term).

I'm Gen Z and I was still "forced" to fix tech if I wanted to use it. I mean sure, I didn't have to deal with IRQs, setting up autoexec.bat and config.sys, and so on, but if you're not at least a little bit inclined you wouldn't have the patience to fix things even when you're "forced". You'd just give up and move on. There's always something else to do. Things have gotten easier for sure, which is reducing the exposure to "falling in the rabbit hole" but one way or another interested people will get into it.
It's like how cars are getting simpler to use, but you still have car guys around. We don't say only old people know how to drive stick.
In any case, there's better things to use as a generational boundary; like how a single G5 piano note will trigger a very specific group of people.
Edit: I went off on a tangent above and got argumentative. My original comment before this one was intended to be sarcastic but tone doesn't carry well over text. This whole thing isn't really something to argue about so I'll leave it at that.
