I’ve seen ZFS in production use on pools with hundreds of TBs, clustered together into clusters of many PBs. The people running that don’t even think about BTRFS, and certainly won’t actively consider it for anything.

• BTRFS once had data corruption bugs. ZFS also had that, but only in very specific edge cases. That case was taken very seriously, but basically, ZFS has a reputation for not fucking up your bits even close to BTRFS
• ZFS was built and tested for use on large pools from the beginning, by Sun engineers from back when Sun was fucking amazing and not a pile of Oracle managed garbage. BTRFS still doesn’t have stable RAID5/6.
• ZFS send/recv is amazing for remote replication of large filesystems.
• DRAID is kind o the only sane thing to do with todays disk sizes, speeds and pool sizes.

But those are ancillary reasons. I’ll quote the big reason from the archwiki:

The RAID 5 and RAID 6 modes of Btrfs are fatally flawed, and should not be used for "anything but testing with throw-away data”.

For economic reasons, you need erasure coding for bigger pools, either classic RAID5/6 or DRAID. BTRFS will either melt your data in RAID5/6 or not support DRAID at all.

Might be something polkit-related? But yeah, you are right about it not working.

I run both NFS and SMB shares. My SMB shares for Windows (very specific application) and MacOS, and NFS for my Linux hosts.

I’m kinda on the fence between them. Both work fine, but the devil is in the details.

Bad enterprise admins running companies without auth, MS getting the blame.

I’m a bit of a casual

I have a mac I use for some specific tasks. I’ll agree the Apple is, ehh, Apple.

But mounting network fileshares is dead simple. My SMB share pops right up, authentication works fine, the user interface for it is fine. If I wanted to use it remotely, I’d just export it over my tailnet.

’sshfs’ is good for short stints of brief use, but ultimately it breaks on a protocol level as soon as your socket dies, on any OS.

NFS over TLS exists, but typically you use kerberos for such deployments. Bit too much for home use though…

To be fair, most higher density areas in Sweden have fairly good infrastructure for public transit. The national railways are a disgrace, but that mostly affects long distance travel. Mostly. Short to medium distance commute works fairly well everywhere I’ve tried it.

And then I store the encryption key in another repo to ensure the compliance checkmark gets checked? (/s)

I guess we can formulate a law:

• Stable
• Easy to use
• Up-to-date

Pick any two.

I’m using ”Commercially deployed” in the context of ”company you interacted with had an AI represent them in that communication”. You don’t use AI for that to increase costumer satisfaction. (I wonder why I haven’t seen any AI products targeted at automated B2B sales?)

I won’t argue that GenAI isn’t useful for end consumers using it properly. It is.

(As an aside, I hope you and your grandfather get better!)

But why use money to innovate when there is profit to be made and laws are just made up?

AI is the new kid on the block, trying to make a dent in our society. So far, we don’t really have that many useful or productive deployments. It’s on AI to prove it’s worth, and it’s kinda worthless until proven otherwise. (Name one interaction with a commercially deployed AI model you didn’t hate?)

So far, Apple is failing with consumer products, Microsoft is backing off on GPU-orders, research showing commercial GenAI isn’t increasing productivity, NVDA seems to cool off and you expect the benevolent commercial health care industry to come to the rescue?

Yeah, I’ll keep my knee jerk reaction and keep living with my current socialised health care.

LLM training is expensive, so are prompt ”engineers”. This will be the cheapest off-the-shelf LLM they can find, prompted by someone’s nephew. People will be eating glue.

Look, this is the reason people pay RedHat money. Go install Rocky Linux, turn on all the automatic updates and ignore it for the next five years.

On the enthusiast side, NixOS seems to be working fine if you want newer versions of software or larger repos.

Used to? It’s standard practice like everywhere.

If you can have NAND-gates, a clock and some wires, you can build anything.

I’ll extend your RHEL corpo parents with the other children in the family. The majority of their revenue comes from completely legal oxycodone sales, any (alleged) trafficking is just a side hustle.

Rocky: The rich corpo parent’s least favorite child. Chill dude. Gives hugs to his parents victims. Still intends to take over the family business and run an oxycodone-empire - but ethically.

Alma: The other reasonable estranged child. Wants to take over the family business, but considers high quality ”herbal remedies” the only pain medication anyone would ever need.

Oracle: Wants to pivot the family business into more potent opioids and possibly world domination. While it’s obvious he has access to ”stuff”, you suspect he has ties to multiple cartels and possibly the yakuza. For some reason has direct numbers to several heads-of-state in his phone.

Exactly, if you need shelf life, you use tape. Shelf life isn’t really a consideration for hard drives or SSDs in real life scenarios.

See for example the storage systems from Vast or Pure. You can increase window size for compression and dedup far smaller blocks. Fast random IO also allows you to do that ”online” in the background. In the case of Vast, you also have multiple readers on the same SSD doing that compression and dedup.

So the feature isn’t that special. What you can do with it in practice changes drastically.

The flaw with hard drives comes with large pools. The recovery speed is simply too slow when a drive fails, unless you build huge pools. So you need additional drives for more parity.

I don’t know who cares about shelf life. Drives spin all their lives, which is 5-10 years. Use M-Disk or something if you want shelf life.
