Perhaps, but my point was more that if you want to grow ZFS this is the ONLY way to actually do it, as far as I'm aware. You can't add individual drives to individual "vdevs."

You can replace all the drives in the array with bigger ones, resilvering after each replacement, and when you get to the last one, poof, you magically have a bigger pool. I certainly won't claim that as terribly efficient, though. :)

It has its shortcomings, no doubt. But compared to old-school RAID or even LVM, it takes a huge step forward.

Though there was a good reason for the original compact Macs to discourage users from opening them up -- there were exposed high voltage monitor electronics in there which could give you a hell of a zap of not properly discharged.

The later all in one Macs of the 90s were better in that regard. Their user suitable parts (motherboard, drives) all were easy to get at, but the monitors and power supplies were fully enclosed.

I will readily admit that as a "shortcoming" of ZFS, but honestly, I don't quite see any obvious use cases for it. On the short term (months), I've only ever needed to *add* storage, never remove it.

On the longer term (years), I have found that I go back and forth on how many drives I need, but when I do eventually upgrade my home NAS to bigger and better hardware, I don't even try to salvage old drives 1/10th the size of modern ones - I bring up the new system, with however many brand new drives I consider appropriate, and clone the old one to the new one.

Ext4 should in theory be the best choice. It's widely used and has a large enterprise support. Lots of business people get angry if it does not work properly.

On a modern system with multiple disks you want to configure as some variety of soft-RAID, ZFS hands-down counts as the clear best choice (short of going for a "cluster" FS). It allows an arbitrary number of extra parity drives (think "RAID 8"), as well as arbitrarily many hot spares; it quickly and easily recovers from having someone pull out all your drives, shuffle them around, and put them back in (for a more real-world version of that - Ever updated your BIOS only to find all your drives remapped?); it detects and (usually) corrects corrupted files; it supports online snapshotting and snapshot exporting to another; it uses dynamically sized storage pools rather than fixed "partitions", and can even grow the underlying total available space.

Then reverse the wires going to the receptacle. An ANSI/SAE J563 receptacle in a positive-ground vehicle would have -12 to -15 V on the can and ground on the tip.

Great idea! Well, right up until whatever you plug in touches anything metal in your car, of course. Then at least you'll have a more exciting day...

an old diesel would be taxed more than a new Euro-5 compliant one.

Believe it or not, the biggest proponents of mile-vs-gallon based taxes in the US have exactly the opposite intent of what you describe.

Some people feel that a gallon-based tax "unfairly" punishes them for spewing 5x more pollution than someone driving an efficient modern hybrid. And don't even get them started on those bastards driving EVs.

These people are increasingly rare, given that more gas stations lack "full-service" pumps.

Well, chalk one up for electrics, I guess.

Tesla's working on automated full-service battery swapping stations. And apparently also on charging cords that can plug themselves in:

Local delivery (Fed Ex, UPS etc) will still have an operator (or perhaps two or more) that can jump out with the package while the delivery truck drives around the block

That's what the Amazon drones are for. The truck just has to cruise through the neighborhood. Meanwhile, small drone aircraft that it carries will work to carry packages out of the truck and to front doors. A human will still be needed for heavy or bulky packages, or for deliveries that have to be brought inside or where there's no convenient place for the drone to land to deposit them, but those packages and destinations can be separated from the others at the local depot, and all put on a smaller number of trucks, therefore needing a smaller number of humans. You won't need a human for every truck if you work out the routes each day based on the nature of the packages you've got and where you're taking them.

I believe the correct response to extremist right wing guff like this is "fuck off to Somalia then you retard".

As a liberal, do you actually approve of your tax dollars funding the killing of brown people on the other side of the planet because something something terrorism ?

download the file, pay $3.49 for it, and print it at home

Umm, no, nice try - I don't pay the original manufacturer to fix their own defective merchandise for them. I would expect them to host files like that entirely for free, the same way PC hardware makers currently let you download drivers.

Of course, I don't actually expect them to do so; but that matters not at all, since countless other sources will.

If you want to arrive unmolested you might try not taking part in an ongoing criminal conspiracy.

Unfortunately, I pay taxes in the US, thereby providing material support to a terrorist organization.

Easy to say "just don't do it", not so easy to spend a few years in Club Fed for resisting the IRS' annual shake-down.
