Excuse me, did they censor the man's eyes in the MRI? Why???

Also make sure you have file extensions enabled in Explorer, it makes it waaay harder for something like this to work.

Do you have a source for that? I am unaware of any modern hard drives that support reading individual bits; the minimum unit of data that can be read is generally one sector, or 512 bytes. If the sector fails to be read, the drive will usually attempt to read it several times before giving up and reporting a read error to the PC.

Data recovery companies can remove the platters from a damaged drive and put them in a working drive, as long as the platters are in good condition, preventing further damage. (If the platters themselves are damaged, you're screwed either way).

If your data is really important, you should send it to a reputable data recovery service. Using the drive any more (even with a tool like SpinRite) risks further damage.

If every one of those users uploads one 10MB file, that would be two petabytes of data. At S3's IA prices that's $25k/month. And people are uploading far, far more data than that.

The 9km mirror I'm referencing is for a sunlight level of illumination; the moonlight mirror needs only be 14m in diameter (or 500m for geostationary orbit).

Some calculations:

In a 1000km orbit, you'll need a mirror about 9km across to appear 0.5° in diameter from the ground (the same size as the Sun), and therefore light up an area with the same illumination as the Sun.

Note that you can't make due with a smaller mirror focused to a tighter area, as the brightest thing the mirror can reflect is the Sun, and so it must appear at least as large as the Sun in the sky to illuminate any point on the ground by the same amount.

With the much dimmer goal of moonlight illumination levels, the mirror shrinks to 9km / sqrt(400,000) = 14.2m in diameter, which is actually rather reasonable. However it would only illuminate an area 0.5° wide from the mirror's point of view, or around 9km. And because the mirror is orbiting at 7.4km/s, you'd only get a second or two of illumination.

TLDR: Moonlight mirror 14m across, could light up a 9km diameter area for a little over a second.

Edit: In the case of a permanent mirror in geostationary orbit, a 500m mirror could provide moonlight illumination to an area around 300km in diameter.

Hahahahah-

Wait... They're serious?

Does anyone really think this could actually work? A LEO satellite would have to be massive (>1 km) to reflect a significant amount of sunlight, and you'll need to put it waaay higher to avoid atmospheric drag. Not to mention the problem of the satellite only being above a given location for a few minutes a couple times a day.

Everyone knows functional programming is the only real programming.

Still, hosting costs were the reason for discussing legal liability. Such a server also increases centralization which isn't ideal.

That doesn't solve the cost problem. Now all the traffic is going through that intermediate server, and someone has to pay for that.
