Even if you think home cluster computing is fun and you're wasting your own electricity, it would be better to contribute to an actually useful BOINC project like folding@home, LHC@home or one of the climate projects.
Exactly. Storing value as bitcoins for any meaningful length of time, or spending money to mine them is stupid. Selling them real fast for real money is smart. This black hat has outsourced the mining costs and is probably selling them as fast as they come in - that's very smart.
They were basically running a charity by allowing people to download maps to their GPS devices with no ad revenue in return, and all that data can't be cheap to store and deliver.
For encryption it may be better to run your filesystem of choice on a drive encrypted with dm-crypt & LUKS. It's totally transparent and can work with any app or filesystem. If you use a filesystem's encryption features it could make recovery more difficult vs. a lower-level transparent encryption system, with dm-crypt & LUKS recovery is no different than an unencrypted drive.
I'm going to switch some of my backup drives to BTRFS real soon now. The filesystem itself is stable and from what I've read, if your filesystem has a problem that the current btrfsck tool can't fix, it's pretty much FUBAR'ed anyways. Waiting time's over.
You could encrypt the storage on the AWS server. Yeah encryption without physical security always means they can rip the key from the RAM, but it's an acceptable level of security for many uses.
HA RAID is a waste for home systems. Is it unacceptable if the home server goes down for a few hours? No? Then don't waste drives on live redundancy, just use backup drives. If you want easily expandable storage use a filesystem-level solution like LVM, ZFS or BTRFS - no live redundancy, just use all the drive space and back it all up to external disks or another server or NAS box.
I'd go further and say that RAID should *ONLY* be used for high availability (RAID 1/5/6) or high performance (RAID0) or in unusual cases where combinations are required (I don't need to tell you if you do data center/supercomputing stuff). For any other purpose RAID doesn't make sense. Want your data safe? Get a backup drive. Want expandable storage? Use LVM/ZFS/BTRFS or some other filesystem-level solution.
Even when you do want to use RAID, if performance isn't absolutely critical I recommend software RAID. Not even firmware RAID like Intel Matrix tech, but slow-ass software RAID, because if you use hardware RAID it's a bitch when you change your hardware. If you use software RAID then you just slap new stuff in and continue like nothing happened.
8TB of porn is completely insane. That amount of video is hard to fathom, but I'll try to put it into context.
One of the many, many complete series I have on my home server's 2TB hard drive (among many other things) is every episode of Bleach from 1 to 345. Each episode is 20 minutes long, plus some 40 minute specials but we'll discount those. Let's call the average episode size about 150MB. 150MB*345=51750MB, 51750MB/1024=50GB which sounds about correct (my Mythbusters collection is around 35GB). How long would it take to watch all that? (20*345)/60/24 = 4.8 days (less than I thought - time well spent I say).
Let's assume his porn is stored at a roughly similar quality, 7.42 megs per minute (that's fairly high actually). (8*1024^2)/7.42=1130540.16,/60/24/365 = 2.15 YEARS OF PORN D8
Beware that these disks come with an unusual partition layout. The 3TB Mybook works more like a NAS than a regular enclosure. A friend of mine took the disks out and plugged them into a Windows box, which didn't like the partition layout and asked some poorly-worded question that was really asking him whether he wanted to write a new partition table to the disk, and he hit Yes. I couldn't recover anything, I even tried photorec but the drive was full of Usenet downloads that weren't preallocated so they were too fragmented to recover.
You don't learn a lot of stuff you should know about driving a car as part of Driver's Education. Most drivers in the Americas are horribly undertrained but it's OK because the IIHS says driver skill doesn't help -_- There are defensive driving courses you can take to learn these things though.
There's not much to it though, basically your steering will start to feel like you're manually turning the rudder of a supertanker (not always true, but 90% of cars with power steering have it for a very good reason), and the brakes will require 4-10x as much force to operate once the reserve vacuum is depleted (you'll get 2-3 pumps of assisted braking once the engine shuts off). If you have an automatic car with a jumbo brake pedal, this is where you use both feet.
They're working on it. Right now the insurance companies are trying to warm you up to the idea by offering potential rate drops if you look like their idea of a good driver.
Most modern cars, yes, but a carbed gas car would probably be fine (uses electrical systems but not electronics) and an MFI diesel would certainly be fine (doesn't even require electricity once started and warmed up).

That's not what the cool guy on the ad said to that boring accountant guy!
You're right, gold is a fiat currency, it's just relatively stable, but not some universal absolute as the Ron Paul fans seem to think.
I saw a flatbed tow truck carrying a lorry the other day. I couldn't get my camera out fast enough.
You could put a Dodge 3500 on a flatbed tow truck and then put a Samurai on the 3500's bed, then put a Peel P50 in the Samurai. Beat that. B-)
Bitcoins are often used on darknet pedo sites (not kidding, this is my serious face |:-( )
LOLWUT? Adobe Reader is a top infection vector, right up there with Flash and the JRE, and MS Office apps are still relatively popular targets.
...from the Rossi cold fusion project! And then you spend the carbon credits to offset your mining rigs and the circle of bullshit is complete.

True, software RAID's speed penalty these days isn't much, that's sort of my point - it's only an issue if performance is super-important.
For encryption it may be better to run your filesystem of choice on a drive encrypted with dm-crypt & LUKS. It's totally transparent and can work with any app or filesystem. If you use a filesystem's encryption features it could make recovery more difficult vs. a lower-level transparent encryption system, with dm-crypt & LUKS recovery is no different than an unencrypted drive.

Sounds to me like it was some kind of work project.

I'll just show up to a first screening. They can't all be fat, right?
Another MS negative-marketing shill. See his post history.
Go ahead and mod me down shill squad. I got karma to burn.

It's not a nice experience, but yes you should be able to or you shouldn't be driving.
Most modern cars, yes, but a carbed gas car would probably be fine (uses electrical systems but not electronics) and an MFI diesel would certainly be fine (doesn't even require electricity once started and warmed up).
Also, what about asphalt-gray cars? It's a popular factory color available from most automakers.
