I originally thought it was one of my drives in my RAID1 array that was failing, but I noticed copying data was yielding btrfs corruption errors on both drives that could not be fixed with a scrub and I was also getting btrfs corruption errors on the root volume as well. I figured it would be quite an odd coincidence if my main SSD and 2 hard disks all went bad and I happened upon an article talking about how corrupt data can also occur if the RAM is bad. I also ran SMART tests and everything came back with a clean bill of health. So, I installed and booted into Memtester86+ and it immediately started showing errors on the single 16Gi stick I was using. I happened to have a spare stick that was a different brand, and that one passed the memory test with flying colors. After that, all the corruption errors went away and everything has been working perfectly ever since.

I will also say that legacy file systems like ext4 with no checksums wouldn’t even complain about corrupt data. I originally had ext4 on my main drive and at one point thought my OS install went bad, so I reinstalled with btrfs on top of LUKS and saw I was getting corruption errors on the main drive at that point, so it occurred to me that 3 different drives could not have possibly had a hardware failure and something else must be going on. I was also previously using ext4 and mdadm for my RAID1 and migrated it to btrfs a while back. I was previously noticing as far back as a year ago that certain installers, etc. that previously worked no longer worked, which happened infrequently and didn’t really register with me as a potential hardware problem at the time, but I think the RAM was actually progressively going bad for quite a while. btrfs with regular scrubs would’ve made it abundantly clear much sooner that I had files getting corrupted and that something was wrong.

So, I’m quite convinced at this point that RAID is not a backup, even with the abilities of btrfs to self-heal, and simply copying data elsewhere is not a backup, because something like bad RAM in both cases can destroy data during the copying process, whereas older snapshots in the cloud will survive such a hardware failure. Older data backed up that wasn’t coped with faulty RAM may be fine as well, but you’re taking a chance that a recent update may overwrite good data with bad data. I was previously using Rclone for most backups while testing Restic with daily, weekly, and monthly snapshots for a small subset of important data the last few months. After finding some data that was only recoverable in a previous Restic snapshot, I’ve since switched to using Restic exclusively for anything important enough for cloud backups. I was mainly concerned about the space requirements of keeping historical snapshots, and I’m still working on tweaking retention policies and taking separate snapshots of different directories with different retention policies according risk tolerance for each directory I’m backing up. For some things, I think even btrfs local snapshots would suffice with the understanding that it’s to reduce recovery time, but isn’t really a backup . However, any irreplaceable data really needs monthly Restic snapshots in the cloud. I suppose if don’t have something like btrfs scrubs to alert you that you have a problem, even snapshots from months ago may have an unnoticed problem.

Don’t understand the downvotes. This is the type of lesson people have learned from losing data and no sense in learning it the hard way yourself.

I believe Waymo’s strategy has always been to shoot for level 5 autonomous driving and not bother with the others. Tesla not following that strategy has proven them correct. You either have a system that is safe, reliable, and fully autonomous, or you’ve got nothing. Not that Waymo has a system at this point that can work under all conditions, but their approach is definitely superior to Tesla’s if nothing else.

Having a synced copy elsewhere is not an adequate backup and snapshots are pretty important. I recently had RAM go bad and my most recent backups had corrupt data, but having previous snapshots saved the day.

This article sums up a Stanford study of AI and developer productivity. TL;DR - net productivity boost is a modest 15-20%, or as low as negative to 10% in complex, brownfield codebases. This tracks with my own experience as a dev.

It’s a weird concept that you buy a device and then have to find an exploit that hasn’t been patched in order to do what you like with it as though you’re a hacker trying to breach someone else’s system, but it’s actually your own system you’re trying to breach.

I use k3s and enjoy benefits like the following over bare metal:

• Configuration as code where my whole setup is version controlled in git
• Containers and avoiding dependency hell
• Built-in reverse proxy with the Traefik ingress controller. Combined with DNS in my OpenWRT router, all of my self hosted apps can be accessed via appname.lan (e.g., jellyfin.lan, forgejo.lan)
• Declarative network policies with Calico, mainly to make sure nothing phones home
• Managing secrets securely in git with Bitnami Sealed Secrets
• Liveness probes that automatically “turn it off and on again” when something goes wrong

These are just some of the benefits just for one server. Add more and the benefits increase.

Edit:

Sorry, I realize this post is asking why go bare metal, not why k3s and containers are great. 😬

Pay surveillance capitalists to track you, except with a verified real identity? I’ll pass, thanks, I will stick to directly supporting creators I care about.

Yeah, I think Netflix has like a few thousand movies and a couple thousand TV shows, and some of us here have similarly sized Jellyfin libraries. On the other hand, YouTube has billions of videos. It seems DRM would be a significantly more difficult and costly problem for YouTube.

Worst part with Meta Quest is it seems you have to sign up as a dev and give them a credit card in order to sideload (a.k.a., install stuff on the device you purchased). So, you can shell out hundreds for one of their devices and the device and all your data are belong to Meta. I assume it’s the same deal with these glasses. Zuck off, Zuck.🖕

Agreed, I’d totally buy a Meta Quest as well if they didn’t zuck up all their devices with spyware that can’t be removed.

Just when you thought Ring cameras raised grave privacy concerns for the public, introducing face-mounted cameras and microphones streaming straight into Zuck’s data centers. Good thing it’s shit and probably won’t sell that well, I guess.

Well, reading the replies to this post, it became clear to me that the title is provocative, but isn’t accurate. Sure, nerds don’t like ads and generally are annoyed by inflated and unsubstantiated claims, but it’s inaccurate to say that marketing doesn’t work on nerds. Many people who read the title obviously recognized this and came here to set the record straight, hence my reference to Cunnungham’s Law. I’m sure others who originally agreed with the title came around to a different understanding like I did after reading the comments and reflecting. “Hey, maybe I’m not immune to marketing after all.”

Overall, I feel like I’ve been called out on my bullshit in this post and am wiser as a result. Hope others had the same learning experience. Maybe I’m a jagoff as well for being so openly reflective about it.

As OP, I have to admit this post unintentionally leverages Cunningham’s Law as its main marketing tactic, as do many other popular posts on Lemmy. Post something that might sound correct on the surface, but is demonstrably false, and you will get hundreds of nerds clicking on it saying, “that’s bullshit; let me set this fucker straight!” 🤣

I ran it on a RPi4 years ago, but it didn’t perform well enough. It performs fine on an old laptop, but not so much in a Pi from my experience. Can’t speak to the RPi5, though.

Yeah, a study with actual data would beat an opinion piece for sure.

So the corporate sites will be more difficult to access and the sites that pirate the same content will be business as usual. Since teens always ask for their parents’ credit cards to buy embarrassing content legitimately instead of pirating them anonymously, these laws will absolutely stop underage viewing.

The Steam Deck is a perfect example of why the title of this post is nonsense. Ha, I added this post early in the morning yesterday and have been facepalming over the dumb title I wrote ever since.

There are unfortunately still useful things that only work on Windows, which is why I still begrudgingly dual boot. I like the idea of ReactOS, but development is slow-going and it’s still only alpha quality at the moment.
