That doesn't create a fully secret ballot.
You can still look up who somone voted for if you obtain their hash number.

The day after voting day deliver your hash number to your supervisor or you're fired.
If you voted the wrong way you're fired.

Rummage through wife's purse to find her hash number card. She voted the wrong way? Beating.

that doesn't look right.
you used MB where I think you meant GB (but that doesn't matter for comparison purposes)
It looks like you're using 1000 GB = 1 TB for your calc so I'll continue with that.

the LOT05 cartridge has a capacity of 1.5TB not 3
So the cost is $0.045 per GB

the LTO4 has a capacity of 800GB
So the cost is $0.031 per GB

The large tapes are more expensive than the sata drive but very close and certainly cheaper than I expected.
Of course they externalize the cost of the tape drives but the cost of that would depend on the size of your operation.
For a huge organization with thousands of tapes it is a small cost.
For a small org or an individual with say 30 tapes it is huge. To back up a 45TB collection (very large for an individual or small business) a $1600 (from newegg) tape drive would add $53 to every tape. So the real cost would be more like $0.081 per GB for the tapes.

Comment Re:What happens when the power goes out? (Score 1) 305

PSTN operates on a separate grid + backup power basis so that it works even in the case of a (normal) power cut. There's no reason that cellular or broadband networks can't be required to do the same and/or don't already do that.

Well, there are a few reasons they can't.
Basically, wireless networks can be battery backed but they can't be generator backed.
There are just too many cell towers and they are in all sorts of inaccessible places. In a power outage you would have to roll out and fuel thousands of small generators to the tops of office buildings, church steeples, hillsides... there's no way.
Just keeping 1500 small generators fueled and running for two days during a major outage would be a huge problem.
With the PSTN's copper network you can battery+generator back a half-dozen COs throughout the city which are dedicated buildings where you can have generators set up.

um well... I wouldn't say 'just as easily'.
There are waaaay more cell towers than COs.
You could put batteries on all of them but you can't roll a generator out to all of them when the power goes down and you have 6 hours of battery life.

With the copper lines they have battery backup and can prep generator backup while the batteries run down.
during the 'great power outage' a few years ago that shut down the north-east Canada/US power grid for days we had working telephones the entire time.

Not needed?
It is an independently powered comms system. It stays up when the power grid goes down, a literally life-saving feature.

Also, the call quality, latency and reliability are still better than the alternatives.

It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.
