Sure, they're nowhere near as smart as elephants, but my cats generally know when I'm up to something, whether that's something that could be used to talk me into giving them treats, or something that might get them locked up into the bathroom and maybe shoved in a box and taken to the vet. One of my cats is better at figuring out treats, and usually pretty dumb about being herded somewhere, while the other one's better at figuring out potential bad stuff, but most cats have at least some clue.
Metadata about you is unimportant and can be obtained by an NSA/FBI/DEA/police/dog-catcher letter saying "please".
Metadata about the NSA is CLASSIFIED NATIONAL SECURITY NOFORN BURN-BEFORE-READING SOURCES AND METHODS that COULD TELL TERRORISTS HOW TO KILL YOUR MAMA and needs to be protected from anybody untrusted, like you, or journalists, or the American public, or the Congresscritters that set their budget.
It's really not that hard, citizen!
RPi already comes with an ethernet port on it, and you don't have to bitbang USB like you would for the standard Arduinos (though there are libraries like V-USB that'll do that for you), and the CPU's a lot faster so you don't have to optimize crypto libraries yourself.) And you can easily attach a keyboard to it for inputting passphrases instead of using the PC, which is critical for doing the security right.
This is an application where you don't need a lot of speed - if it takes a second to cough up a password, that's fine, so you don't need a $3 hardware crypto chip to go with the $1 ARM CPU, though of course you certainly could make a much cheaper piece of ARM hardware if you wanted.
English words average between 1-2 bits per character. 10 random characters may be good for 80 bits if you can really use 2^8 values, or maybe 65 bits if you're only choosing randomly over 92 values per character, but if you choose actual words for your password, it's a lot less. The OED has about 200K words (~18 bits), so you get maybe 20-24 bits depending on word endings, l33t-spellings, capitalization variants, combinations of short words, etc.
128 bits is theoretically sort of secure today, as long as it's used in ways that aren't susceptible to birthday attacks (probably not an issue here), and as long as there's enough real entropy used to generate those bits. Even that's a realistic problem here - are you going to remember a passphrase that has 8-10 random words from the OED? Or are you going to have to keep them written on a yellow sticky note in your office, or dogear the pages in your dictionary that have words highlighted in 7 different colors so you know what order they're in?
The original Daleks couldn't go up stairs, so they'd be useless in my place. But they do have a plunger arm, which can be occasionally useful.
You can look them up; I saw them in the local newspaper a few years ago. I don't remember what the grunt officers made, but the police chiefs in Palo Alto and Mountain View make about $300K (and I think even the second most expensive cops were over $200K.) And that's in a town where almost all the crime is white collar.
On the other hand, Facebook's closer to East Palo Alto, which is across the county line from Palo Alto, and is the town where the poor people were allowed to live back when there was racial segregation.
Not only is there the cost for insurance and pensions, and equipment like police cars, but also 1/N the cost of their boss, and 1/N**2 the cost of their boss's boss.
And if you look up the salaries of Palo Alto employees (which are public record), you'll find that cops in Silicon Valley get paid a lot; I think the police chief makes $300K (which probably includes benefits), but I may be mixing that up with Mountain View's police chief. And yes, these are towns where almost all the crime is white collar. I doubt Menlo Park is cheaper.
That's really what Einstein's paper was about.
I started playing with Arduinos a couple of years ago (no, not "before it was cool", but before Radio Shack started carrying them
(Of course, it's much more interesting to get components at Hal-Ted or Weird Stuff, but that's a much different market.)
No, lifehacksaur111, this doesn't mean that the military-industrial complex is being dismantled or that the war machine is being downsized. It just means that the military understands that they aren't going to be able to get enough budget to pay for both the important stuff (pork-barrel military-industrial-complex spending) and having lots of soldiers around needing pay, housing, and medical care, so they're prioritizing how they'll spend the money.
And if later they need more soldiers for cannon-fodder in a large war, they'll see about cranking up a draft or something, but for now they don't want to lose the pork barrel.
It's not like nobody's ever declared they're done and shipped code without testing it first, or without fixing all the bugs they found, but they obviously didn't test this one.
Fail: goto fail;
Most of the proof-of-work systems out there are really demanding that you waste some amount of money, time, or both, to prevent people from just generating arbitrarily high numbers of coins (as opposed to the Hitchhiker's Guide To The Galaxy use of leaves as coins.) Bitcoin number-crunching is purely wasteful potlatching. Dogecoin is such wow, so calculation!
At least this one is doing a kind of work that's potentially valuable to the world, assuming the system collects all of it in a way that can be used to contribute to mathematical knowledge. (Yeah, yeah, this is
Hey, what's your serious response doing here, in between all the suggestions about sharks with frikkin' lasers?
NIF was always really about fusion research for the nuclear weapons programs, just as almost everything else at Livermore Labs was either related to weapons research & development, or infrastructure for the R&D folks (e.g. they did some good development on email systems back in the 80s because their R&D folks needed good email.) Some of it's more direct development, some of it's more basic science, but even then it's basic science intended to help weapons research. They've occasionally done other things (some solar energy research or whatever), but that's a drop in the bucket, and a lot of the environmental research they did was either trying to figure out how to clean up the messes their weapons folks made or the messes left over from the previous Navy base at that location.
You really don't want to park in the wrong place at Livermore Labs. I don't know if they're still running the 5-story-high magnet they had back in the late 80s / early 90s when I went to some graphics conferences there, but if they can't just pick up your car and move it out of the way with the magnet, now they've got the Big Laser. Also don't go parking near the "No Parking - Spilled Plutonium" signs (though actually the nastier environmental problems they've had there have been leftover junk left over from WWII when the Navy was using the place - solvents that weren't yet known to cause cancer, or maybe they already were known to cause cancer but were still really effective solvents, the occasional leftover explosive, etc.)
