L2ARC only does metadata out of the box. You have to tell it to do data & metadata. Plus for everything in L2ARC there has to be a memory page for it. So for that reason it’s better to max out your system memory before doing L2ARC.

It’s also not a cache in the way that LVMCACHE and BCACHE are.

At least that’s my understanding from having used it on storage servers and reading the documentation.

I used to do this all the time! So in terms of speed bcache is the fastest, but it’s not as well supported as lvm cache. IMHO lvm cache is plenty fast enough for most uses.

Is it going to be as fast as a NVME ssd? Nope. But it should be about as fast as a SATA ssd if not a little slower depending on how it’s getting the data. If you’re willing to take that trade off it’s worth it. Though anything already cached is going to be accessed at NVME speeds.

So it’s totally worth it if you need bigger storage but can’t afford the SSD. I would go bigger in your HDD though, if you can. Because unless you’re accessing more than the capacity of your SSD frequently; the caching will work extremely well for both reads and writes. So your steam games will feel like they’re on a SSD, most of the time, and everything else you do will “feel” snappy too.

Nope.

How much of a difference does the AMS make in terms of a general printing? If someone wasn’t planning to do multi color prints often or at all would it still be worth it?

I was thinking about that or an A1 Mini

Why? And what would be a replacement for it?

Didn’t work at all for me. Tried it when stimulants were nearly impossible to get. I gave it a few months too. When I was finally able to stimulants again I was able to get back on track with things. That being said I’ve heard for some people it’s worked well. Though no one I know in person has found that to be the case, so YMMV

For similar reasons that’s why chewing is important too.

MacOS, nearly everyone who does anything with development or ops is using a MacBook. Though lately more “normal” employees have been getting MacBooks too.

Waaaaay better.

Restic allows you to make dedupe snapshots of your data. Everything is there and it’s damn hard to loose anything. I use backblaze b2 as my long term end point / offsite… some will use AWS glacier. But you don’t have to use any cloud services. You can just have a restic repository on some external drives. That’s what I use for my second copy of things. I also will do an annual backup to a hard disk that I leave with a friend for a second offsite copy.

I’ve been backing up all of my stuff like this for years now. I used to use BORG which is another great tool. But restic is more flexible with allowing multiple systems to use a single repository and has native support for things like B2 that BORG doesn’t.

We also use restic to backup control nodes for some of supercomputing clusters I manage. It’s that rock solid imho.

Yeah that was my thoughts too. It’s not like it can’t be bypassed but it’s not “easy.” This is kinda how I see it going for commercial 3D printers. It’s not a bad thing either. I’ve always been a fan of making people earn dangerous knowledge & skills. Even in fictional universes like Star Trek there’s restrictions on using a replicator to make weapons.

So it’s not unreasonable, imho, to put some kind of guard rails up that force people to actively bypass restrictions in making weapons.

The trick will be telling the difference between making a nerf gun, action figure guns, and an actual weapon. That I don’t see being possible at this time. Too many edge cases that don’t neatly fit.

It’s all good, hope you find a solution that works best for you 😊

You could also just grab a wire guard configuration and use it too. They provide them along side the openvpn configs

To be honest, there’s a few good comments linking to scripts and methods here to batch convert them on a windows pc/vm. That’s the best way to go.

To add on to their comments. If you’re just interested in preserving them then maybe printing them to pdf, specifically pdf/a, would be my approach once you got them opened.

I’ll leave this one here for someone:

You can tunnel L2 over OpenVPN. Just bridge your interfaces in both sides and it works.

That way if you need to provision a VOIP phone or just have something NetBoot remotely. Not that I recommend doing that…

Restic

Sucks for them, because I’ve moved over to Pathfinder after Hasbro tried to screw us and gutted WoTC. Most people I know have done the same too. They had plenty of opportunities to make it right and just kept rolling a 1 each and every time. Shame too because I love 5E

Like everyone has said there’s way better ways of doing it.

HOWEVER if you wanted to use dd you totally could. I’d recommend piping into something like gzip/zstd to save some space though.

dd if=/dev/sda | gzip >/mnt/backup_disk/sda.gz

You could also use restic backup the raw block device too.

That being said, clonezilla is exactly what you want

I don’t know of any, I know that at one point you could enable it on one plus devices since outside the US it has that functionality built in. There was an app called j.one.plus.tools that did it IIRC.

The upstream dialer might have some functionality like that built into it too.

Everyday. I’ve got a lot of stuff that uses it. Granted most of it was mostly created a decade ago but with minimal maintenance it works great. The most helpful script is parsing megacli outputs so I can get a heads up on drive failures and rebuilds among other things.
