LTO4 tapes do seem to hit a good price/capacity point, but where can you find even a heavily used LTO4 drive for $50? Also, LTO4 (or just about any other drive type) isnt going to just plug in to eSATA or USB3; you need a SAS/SCSI adapter plus a PC capable of hosting it, which balloons the cost.
Glacier at $20 per month for 20TB is rediculously cheap by today's standards. And at those sizes, you'd want to ship those drives to Amazon instead of uploading. We do this all the time and it's not that hard.
The price of TBs of storage of course will come down without question. But by today's standards $20/month for a medium that won't "bit rot" on you is an amazing deal.
You missed a 0, he has 20,000GB and the cost for glacier is $.01/gb/mo (not including upload charges). So, Glacier would cost him $200 a month or $2400 a year. Not hugely expensive but if you are OK with a quasi-local copy (offline and stored in a fire safe, perhaps) you could do it cheaper for less, after you hit the 1 year mark.
After all, your friend could just as easily wipe out the 2nd array by mistake
This is exactly the core issue to protecting his data... I would propose what he really needs is a nuclear launch key style interlock that only lets him access his backup array when both keys are present, and give it to a smart friend (along with a shovel) tasked with looking over his shoulder when the key is in use, ready to hit him over the head if he keys in a command involving dd, fdisk, rm -rf, etc.
It's not like you could just plug in an external drive, and using any cloud service would be terribly expensive. Blu-Ray discs can hold a lot of data, but that's a lot of time (and money) spent burning discs that you likely will never need. Tape drives are another possibility, but are they right for this kind of problem? I don' t know. There might be something else out there, but I still have no feasible solution.
Lets start from the top: You *can* plug in an external drive, it's called a complete hardware duplicate of your array (or perhaps for space/cost consideration, a single disk based copy held offline and synced regularly). Not hard and not terribly expensive (i would go with this solution personally). Cloud? Yep the bandwidth and storage even on something like Amazon Glacier would be prohibitive to all but the most financially independent geeks. Bluray doesnt hold enough (even at 50gb/disc you need 400 of them, groan). So, tapes? You bet your ass tapes are designed to do exactly this task, why do you think they are still in use? You can get individual tapes at 1/1.5TB, but for a one man operation they are probably going to cost you more than the first solution (offline spinning disks) and they are a pain to manage properly.
Now what is this doing on ask slashdot? A pencil, some scratch paper, and 15 minutes between amazon.com and newegg.com would tell you the prices of every solution. Oh, right, they need a chance to tee up some targeted ads for Carbonite, Mozy, Crashplan, etc.
Editing your own article on Wikipedia is not prohibited as long as you disclose your conflict of interest and follow the rules, so I have trouble seeing how this submission is anything other than yet more manufactured controversy and/or anti-Wikipedia astroturfing.
In slashdot's defense, they did use the *link to the wikipedia page* of wikipediocracy in describing their role. A golf clap is in order.
This is quite an interesting idea. DYI drones are getting more and more common - and there are plenty of people with electronics background who can make the control interface.
Make the commands sent to the drone be sent encrypted/signed - allowing automatic handoffs between controlling terminals.
It would be pretty easy to make drones do the 'chore' of crossing international borders for you. Just put out a couple of 'base stations' that are quiet unless the drone is coming by
I'm wondering how well prepared border control / custom agents are for taking down fast moving drones that sweep in pretty low.
Border patrol (and just about every other agency with an enforcement mandate) is already exploring UAV use, what we will see eventually is an air war where unauthorized UAVs are simply shot down automatically.
Wouldn't Walter White count as a chemical engineer?
No because making meth good enough for consumption/addiction is hardly a feat of chemical engineering; meth heads will consume actual shit, poison, air, rocks, etc if they thought there was the slightest chance of a buzz.
His exploits obviously color him as a social engineer (hacker alert!!!!!)!!!
If you are a casual technogeek, save yourself about $4000 and just go on AliExpress and buy whatever knicknacks you are interested in straight from Shenzhen. What, did you think they haven't figured out ecommerce? If you do have the chance to visit (i.e. for work), or are really after niche goods/services (in particular, to start your own import business) then certainly its a great place to go. But if you are just looking to get out of the US, don't go to Shenzhen just to browse around Huaqiangbei. There are plenty of other, far far more exhilarating/enlightening/relaxing places to visit in the world.
Except that I do understand how it works, and definitely do not like the idea of having that kind of product around. But yeah, I must be buying into fear and hype because there's no other reason for people to not like the idea of having a fairly concealed recording device that may or may not be recording.
Unless you are willing to attack anyone who is wearing a mildly loose overcoat, or a slightly thick pair of glasses, or is carrying a bag any bigger than a cellphone, then yep you are buying into the hype because all of those things can/will record you and you will never know it. So, don't be a sucker who buys into fear and hype, get out there and go apeshit on the next person you see wearing a device that "might" be recording! I will write to you in prison. I promise.
The mathematics of bitcoin are sound enough. The issue I have with it is the possibility of hacks.
We all know that most computer systems are insecure. In the past, cracking a computer could only yield things like names, addresses, passwords (hashed and salted, one hopes), confidential files... in short, information. But with Bitcoin, crackers now enjoy the tantalizing possibility of stealing money! That makes Bitcoin exchanges (and, if bitcoin becomes popular, all ordinary PCs with bitcoin wallets) highly attractive hacking targets. So how can we be sure that an exchange won't be hacked? How can we be sure that our PCs won't be hacked? This issue--my inability to know that my coins are secure--has made me reluctant to buy them in the past.
Not sure if... Tolling, or posting from 3 years ago.
The prospect of stealing money is at the heart of most small time cracks, after all a complete identity, or even a banking password or two is as good as cash. Bitcoin already enjoys steady attacks on exchanges, as well as malware designed both to steal existing wallets and to steal CPU cycles in hopes of turning them in to BTC. Keeping a bitcoin wallet secure has never been any different than keeping a real wallet secure, though. If you made a copy of all the stuff in your wallet and put it on your PC (short of cash) then a thief can steal everything of value in your wallet. If you keep a copy of your bitcoin wallet on your PC the same is possible, and just like a real wallet you can easily move your bitcoins to a portable media, erase any trace from your PC, and keep the entire thing in your pocket.
Bull. I live near Saskatoon Saskatchewan, a small city by north american standards. When my wife and I bought our home, we were forced to choose between the ghetto (where crime is DOUBLE anywhere else in town) or to move out of the city. With our first child on the way it was a no-brainer.
To move to a downtown area that isn't crime-ridden would cost TWICE what we're currently paying.
It is undoubtedly worse in larger centers.
You are saying bull and then agreeing with me? Safe inner city areas exist and are higher priced, plain as that. Im not judging your particular situation but you are choosing the commute/work in the suburbs option and theres nothing wrong with that but it is not the only option that involves living/working in a safe area.

H= Hospital, Museum and Park district.
We have no zoning in houston but deed restrictions and politics prevent random rampant reuse of land. You typically see areas shift very slowly to new purposes over a couple decades. Developers TRY to force this (Our "Galleria Area" being an example) but often fail the first couple times before the idea "takes" (The galleria was basically empty and tiny for a looooong time-- today you can't even find parking and it's full to the gills--- so full a lot of people won't go there any more. lol)
Thanks for the elaborate description but I would have clicked an imgur link too...
More like putting money on your safe. A safe that can instantly teleport it anywhere you want.
A safe with a teleporter on top of it sounds like a HUGE security risk. Maybe you should put your money IN the safe and put the teleporter in the next room. And dont put teleporters in every room, you will be tempted to use them when its not necessary and your head might end up on backwards.
Now the only thing that can destroy the value of your coins is... oh, everyone else who's still dumb enough to value convenience over personal responsibility. Que sera.
If this doesnt end in total collapse, what it will mean is that the thieves will horde the 740,000 BTC leaving the pool of fungible coins for actual trading small, which will mean its value will be higher. So unless the thieves manage to spend all their loot (that would take forever given how long it takes for cocaine packets to ship) then really the prudent users are better off.
Ummm... people move to the outskirts of a city so their kids don't have to fear getting mugged or shot in crossfire between inner city gangs. You cannot raise children in almost all US cities safely, so virtually any fit parent has to do the suburban thing so the strays the kid sees are puppies and kittens, not
You are confusing the downtown (city core) with the blighted near-suburbs. Few cities have truly crime-ridden core areas, but many have suburbs that are so. They also have a core and near-suburbs that are much safer (and naturally higher cost) which is where the truly affluent (or perhaps single/childless) live, while the rest endure the commute in favor of the extra space they can afford in the far suburbs.
