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.
ALL AF bases and the majority of the the other services did away with base stickers several years ago and now everyone in the vehicle over the age of 16 has to display a valid Government issued ID to get on base.
All? I'd swear last time I accompanied my father (retired AF) on base at either Nellis or Wright-Patterson, the skycop just asked for his ID, not mine. It might be different overseas, and it's been different here at various times in the past, but unless they've changed things yet again since this past December, they most likely only care about the driver's ID.
any project or developer that uses it is going to need that backup repository at github anyway
You should have backups of all your projects to media that you control in any case. Google has a track record of winding down stuff it doesn't want to continue (Reader, anyone?), but if you're betting on any source-code repo to (1) not go tits-up (as Google Code might) and (2) not jump the shark (as SourceForge has), you're putting your code at risk. Git, in particular, makes it dead simple to clone a repo and all its history in a relatively compact form, so spare a few GB on a server you control for a mirror of everything you put on GitHub (or whatever).
....and not a word about TrueCrypt? is there any commonly used alternative or people just don't care?
I migrated to FreeOTFE right around the time that the TrueCrypt developers said people should stop using it, about a year ago. I haven't had much reason to migrate back (though TrueCrypt's hidden volume feature was nice to have).
