Maybe just me, but all the contexts I ever saw WinRAR in convinced me that it was always sketchy AF. In any case I don't think I've seen it in 10 years.
"Is there a software solution, like a file system or a file format, specifically tailored to avoid this kind of bit rot?"
Yes, ZFS is specifically tailored for this. Configure a zpool running RAID-Z2 with a hot spare or RAID-Z3. Half a dozen 6TB or 8TB disks should suffice.
Set it to auto-scrub regularly. Send logs and warnings to your email, and pay attention to them. (This is the hard part). Especially pay attention if they stop arriving. (This is even harder).
I have used Nexenta for some time, but the free product has a limit of 18TB of raw storage. If I was starting today I would use FreeNAS which has no such restriction.
The other comments about the futility of trying to do this long term are worth heeding, but that doesn't mean you shouldn't try. They key is to make this an active project rather than a passive archive, and to re-evaluate the best approach every few years.
No, it's not the same as using multiple channels in parallel. TFA clearly says it's a single channel.
And yes, you could get this using "existing technologies" if you could use all the spectrum from 0 to 25GHz, for instance. The problem is that most of that spectrum is already in use.
If only Apple had the money to buy their own infrastructure...
Apple is a very rich company with $200bn+ in the bank. They got that way by taking every opportunity to grow their business. Nothing wrong with that. But sometimes that entails doing things that might not be in their best long-term interests.
Consider this: they chose to buy cloud services from other vendors because their business was growing beyond their ability to provision these services in-house. They could have chosen to do it themselves, preserving the integrity of their infrastructure, but that would run the risk of not being able to scale it out as fast as their customers demanded it, and limited their growth.
So they made the choice to outsource, maximizing their growth but taking the risks that come with that approach.
They could have taken the other path and kept their integrity. They are one of the few companies rich enough to do that. But it's not in their DNA, and their stockholders would take a dim view.
So now they have to take pictures of motherboards in the hope that they catch the bad guys doing something. Pathetic really.
I just got back from a 6-day visit to Iceland. For the first time visiting a foreign country, I completed the trip without needing to acquire any local currency. I paid for everything using my US-based credit card using chip and signature. A couple of transactions (pay and display parking) were automated without any need for either PIN or signature.
There's a lot of urban myth about this. In UK law the tolerance is actually 10% + 4kph, or 2.5mph, and it applies to the speedometer in the car, not to the true speed. This is merely a wiggle factor allowed for the speedometer in the car, which is allowed to read high up to the above formula, but never low.
So for a true speed of 70mph, the car's speedometer may legally display between 70 and 79.5. So it is not a excuse to speed, as the tolerance is only on the upside. A speedo that reads low is out of spec and illegal. Thus most cars have speedos that read a little high by design, in order to comply with this regulation. In my experience about 5% high is typical, so 73.5 indicated for true 70.
AFAIK any allowance by the cops over the true speed is entirely at their discretion. In theory you can still be ticketed for 71. IMHO this is a good thing, as it allows boy racers to surge along at an indicated 85, while still actually within what most cops would consider a safe envelope.
This policy is in everyone's interests: - the car manufacturers like it because the wiggle factor means they can build the speedo to a lower, cheaper standard; - the enthusiastic driver likes it because it gives an exaggerated impression of the car's performance (I was doing 100!^H^H^H^H90!); - the authorities like it because it curbs excessive speed and thus enhances safety; - we geeks tolerate it because we have our own independent measuring equipment.

Time itself is an illusion. Lunchtime doubly so.

Indeed. It is clear from this incident that only City Council members are permitted to exercise their right to embarrass the city.
