Still more reliable than an optical disc. The real backup is on RAID6

RAID isn't backup.

Getting a college degree, you actually learn something.

I've run into more than a few people who have made it through college quite uncontaminated by knowledge.

I'd argue that there are even some college curricula that will leave their students less prepared for the real world than if they had just gone straight into the burger-flipper and barista jobs that are the only types of work they'll ever land outside academia. You can identify most of them by the presence of the word "studies" at the end.

The drivers in California aren't necessarily bad, but they are much more aggressive and more likely to do something stupid out of impatience.

California drivers never heard of lane discipline. They think nothing of (as Denis Leary might put it) "driving really slow in the ultra-fast lane," or of passing the aforementioned assholes on the right.

Well, i want to do something on Android, so Java is the way. :(

Yes, Java is still ugly, but at least it's consistently ugly.

I suspect there are two problems for them in being too clear. First, I suspect they can't guarantee to reuse every cartridge - some of them will be damaged or contaminated, I imagine; second, they won't want to validate third party cartridge refills by admitting they actually do refills themselves! I recycle my Lexmark cartridges by mailing them back (with a prepaid shipping label they include with every new cartridge); my guess is they will refill and reset perfect-condition cartridges, recondition damaged or older ones, and recover the raw materials from unusable ones, but they won't want to be too open about the details. The "new" cartridges aren't exactly cheap, admitting they're sometimes actually refills would probably hurt sales.

How is using blu ray cheaper than hard drives?

3 TB will fit on 120 25-GB BD-Rs. At 40 cents each, that's $48 in media costs. If you do like I do and reserve 20% for dvdisaster error-recovery data, you're still only looking at $60.

A 3 TB WD Green will set you back $95. (Want to spring for the NAS-rated Red drives instead? That'll be $119. Their absolute cheapest 3 TB hard drives are a couple of models from Seagate and Toshiba at $90 each.)

The trick is getting BD media into the terabytes and getting it at a price point where it is decently affordable. For example, a 100 GB BDXL disk is $65, but it should be about 10% of that price in order to be a viable backup medium.

My last spindle of 25 GB BD-Rs cost me maybe $0.60 each or so. I could drive down to Fry's right now and pick up a spindle for about $0.80 each. A 4x increase in storage density isn't worth a two-order-of-magnitude increase in price. I would be surprised if Farcebook didn't arrive at the same conclusion.

Going by the numbers from the video in TFA, they're getting over 10k BD-Rs in a rack. While the basic concept isn't new, they appear to have developed it to a considerably higher density.

If they are storing their photos on facebook, they are doing it wrong.

FTFY. I can kinda understand posting stuff to Farcebook so others can view it, but using it as your primary storage medium? That's at least a dozen different kinds of wrong.

I don't dumpster dive much more these days, it's not worth the effort.
