Same here.

It's not built in, but it is integrated. Just use
zfs set sharesmb=on pool/srv

If you are having perms issues, make sure you have acl support enabled in your kernel and userland, and then use the aclinherit property on your zfs pool. Samba should handle the translation between NT and posix ACLs seamlessly, but you may need to use Samba4 for the best results.

Super Dracos are for escape in flight too, including in and past MaxQ. But they are on Crew Dragon, not Cargo Dragon. Cargo Dragon did not carry a crew and wasn't programmed to save itself.

Most of us do have a need to transmit messages privately. Do you not make any online purchases?

Yes, but those have to use public-key encryption. I am sure of my one-time-pad encryption because it's just exclusive-OR with the data, and I am sure that my diode noise is really random and there is no way for anyone else to predict or duplicate it. I can not extend the same degree of surety to public-key encryption. The software is complex, the math is hard to understand, and it all depends on the assumption that some algorithms are difficult to reverse - which might not be true.

I don't disagree with anything you have said. We use ECC RAM in our servers. My contention was only with the statement,

implying that ZFS is somehow a special case from other filesystems. It's not.

I'll go with one of the co-architects of ZFS, Matthew Ahrens,

In other words, there is a non-zero chance that you will get silent data corruptions on disk if you don't use ECC RAM. It is the same risk with ZFS as with any other filesystem. And yet, personal computers have been running without ECC RAM for decades and it hasn't been a travesty. So yeah, if you are running in the type of situation where you absolutely must ensure the highest level of data integrity, then you must use ECC RAM. If you are running your own personal home media NAS, it is probably not an unmitigable risk to buy cheaper hardware. The storage gurus will argue, "Why use ZFS if you don't care about it's data integrity features?" My response is that ZFS has a ton of other very useful features that make it a great filesystem.

BTW, bad vs. good RAM is not the same thing as non-ECC vs. ECC RAM. While ECC RAM will protect you from bit flips, a bad stick of RAM is still a bad stick with or without the extra parity bit. Aaron Toponce has a good (non-sensational) discussion on the topic,
https://pthree.org/2013/12/10/...

Most algorithms to do this use the time between keypresses, measured to very high precision so that the lower bits are chaotic. So it doesn't really matter what keys you hit, and it doesn't matter how rythmic your typing is.

The problem with FM static is that you could start receiving a station, and if you don't happen to realize you are now getting low-entropy data, that's a problem.

There are many well-characterized forms of electronic noise: thermal noise, shot noise, avalanche noise, flicker noise, all of these are easy to produce with parts that cost a few dollars.

True randomness comes from quantum mechanical phenomena. Linux /dev/random is chaotic, yes, enough to seed a software "R"NG. But we can do better and devices to do so are cheap these days.

I wouldn't trust anything but diode noise for randomness. If I had a need to transmit messages privately, I'd only trust a one-time pad.

Owncloud is a poor substitute for a fileserver because everything has to be owned by the webserver user at the the filesystem level. All of the access controls and versioning is handled by the owncloud webapp. So if you need to operate outside of the owncloud environment you are screwed, like for example using owncloud's dropbox-like client for easy syncing and at the same time exporting the filesystem via Samba for people to map network drives.

If you export the filesystem via Samba, you can enable the VSS compatibility feature, which allows Windows users to access the "Previous Versions" tab. There is no equivalent for other Mac or Linux clients, or other network filesystems (NFS, etc) that I know of. It would be a nice feature to have.

Nonsense. ECC RAM may help avoid certain kinds of on-disk errors, but it's a heavily debated topic. Your statment,

is completely unsubstantiated BS.

Ahem,

Communism has been tried on a large scale - see Mao's Great Leap Forward.

Nope. That was a totalitarian socialist program pushing a collectivism that didn't work. Communism is a post-scarcity society and obviously scarcity was the thing Mao produced best.

Whatever it has been used for subsequently, A113 is a classroom at Cal Arts.

I didn't actually work on GPUs very much at Pixar, the image computer I worked on was the grandfather of the SIMD image processing instructions on modern CPUs. What would become a GPU later on was a very expensive box from Silicon Graphics, I had one that cost at least a quarter Million dollars.
