Yes, absolutely. Right now, SSDs are probably superior in comparison to HDDs in every category except for price (and long-term data integrity when switched off). But when you consider large parity raids and take into account the cost of electricity, even the price difference might only be small, making SSDs even more attractive.

Hmm. Let’s say I add 6 SSDs, 2TB each, for a total of 600€. In a RAID6 configuration, that gives me 8TB of storage. Compare that to a classical NAS with 2×8 TB HDDs for a total of 350€.

The HDDs will draw around 4W idle each, 8W in total. Assuming 0.3€/kWh, over a span of 5 years, that is approximately 100€. The power consumption of the SSDs will be negligible.

So, just in terms of storage, the SSD solution is around 33% more expensive over 5 years. If you include the cost of the NAS itself, the price increment is even less noticeable.

Very helpful. I was just looking at this the other day.

You can have untrusted peers in Syncthing that only receive an encrypted copy of your data.

Not the case I was thinking about, but here is a similar case:

[translated] Parking in a stupid way can be expensive. In Frankfurt, the regional court has ruled that a car driver must pay for the use of 28 cabs.

[…]

The cabs collected people waiting at the stops and drove them to other stops along the route. This went on for an hour before the car parked not far from a “Please keep enough distance from the track” sign was towed away and the route was free again. […]

When the VGF then demanded 973.13 euros, 25 euros of this was a lump sum for their own expenses - and the rest was the cost of the rail replacement cabs. The court ruled out manipulation by the cab company after hearing witnesses, and the court was also unable to recognize any dilly-dallying during towing.

The car driver did not have any legal grounds for not paying for the cabs, this only went to a court because they tried to accuse the cab company.

Someone in my city did this. Their car blocked the tram. The tram company ordered taxis for all passengers, and the car owner had to foot the bill.

I just checked, and I have connectivity while on cellular. Maybe (just wild speculation) your mobile network is IPv6-only? Android (not Linux) should list 192.0.0.4 as an IP address in that case.

[–] shadowtofu@discuss.tchncs.de 5 points 3 months ago

Yes, Linux is running in a VM, and the network interface is a virtualized veth interface connected to a host bridge. The host android system has IP address 192.168.0.1, and this network interface is called avf_tap_fixed (as seen from termux).

While this is very exciting, I just tried it, and the network connectivity seems to be broken. No IPv6.

Building nuclear power plants is not a science problem, though, it’s an engineering problem. Just because we can harness energy by breaking up nuclear bonds does not mean that we can do so economically, given the constraints under which we have to operate power plants.

And OP never disputed the science anyways?

I met someone that was throwing out old memory modules. Literally boxes full of DDR, DDR2 modules. I got quite excited, hoping to upgrade my server’s memory. Yeah, DDR2 only goes up to 2GiB. So I am stuck with 2×2GiB. But I am only using 85% of that anyways, so it’s fine.
