Thanks for the write-up!

I see now I was conflating zfs with RAID in general. It makes sense that you could have the benefits of a checksumming filesystem without the need for RAID, by simply restoring from backups.

This is a great start for me to finally get some local backups going.

Can you explain this to me better?

I need to work on my data storage solution, and I knew about bit rot but thought the only solution was something like a zfs pool.

How do I go about manually detecting bit rot? Assuming I had perfect backups to replace the rotted files.

Is a zfs pool really that inefficient space wise?

As I understand it, there’s a range of sizes that are problematic, from small to micro to nano and beyond.

The problem is the more plastic we make, and the smaller it starts, the easier it is for it to get worn down into smaller and smaller bits that become more problematic for us.

One of the problems with all the macro plastics in the ocean is that that as they get churned up and baked in the UV from the sun, smaller and smaller bits break off and become part of the… Everything.

Micro plastics are so prevalent that they can’t even do proper studies on how harmful it might be to us, because there are no control groups that have no plastics inside their bodies to compare against. Even babies in the womb have plastic in them. You have plastic in you right now, almost a 100% guarantee.

There’s probably more to it than that even, but that’s my understanding of it.

I used to like the a400, had a few of them in service, but a few years ago I tried another one and it was terrible. Just… Slow… like an HDD. I did some research and apparently they changed something with the nand somewhere along the line. Did a bait and switch. I don’t remember the details but it annoyed me.

I actually needed to buy a budget SSD just today, and I got a BX500. We’ll see how it goes. I know not to expect much from a drive without DRAM, but at least I know that going in.

Wait wait Wait, can you give me more on this kWh thing? I thought I understood this already.

A single kW is a unit of power, literally 1000 watts.

A kWh is a unit of energy, as in stored or delivered. Draw 500 watts for 2 hours? That’s a kWh. Or have a battery that can hold 1 kWh, then assuming 100% efficiency you could draw 1000 watts from it for an hour before it was empty.

All of this is kW times hour, I would say? But in my mind I would interchangeably say per hour as well, they feel the same.

Obviously I’m wrong, but I’d like to know why lol

Spotify maybe, I’ve never used it. And Google Play music used to be the best for this, but YouTube music has me stuck in a loop of my last 10 or 20 songs and I hate it.

If I’m listening to some techno, and I change gears to old school country/bluegrass for awhile, then, YouTube will never ever recommend techno to me again. Not unless I manually remember some of my favorite songs, search for them, and retrain it that I like techno. But then of course country slowly dies. God forbid I mix in hard rock, punk rock, or rap. It just confuses it more.

And it’s not just a genre problem, even within a genre of repeats the same dozen or two songs every time I open the app.

It’s not just me, I have a family plan and my brothers have both separately complained to me about the algorithms being worse than Google Play music, which is what we used to use.

I literally created a playlist called YouTube music sucks, where I save my most liked songs, so I can reseed the algorithm when I want a change of tunes. I need the playlist because I have a terrible memory and can’t remember all the songs I’ve liked.

Why don’t I change? Because I’m cheap, and it’s bundled with YouTube premium for the whole family. And it has no right to be as bad as it is. I keep thinking they’re gonna fix it, but I guess maybe people like being spoon fed their last 20 liked songs?
