Yeah if they get cheap enough, I'm sure private individuals/corporations will be buying them for all sorts of reasons. Add face tracking and recognition for profit.
Let's see how the cops, their bosses (and mistresses?) like it when we start watching them too.
I'm not afraid of terrorists with flying cars. I'm afraid of the flying cars being controlled by the average driver or an AI that's only a bit better. Imagine thousands of 2 ton flying cars whizzing around at 100kph controlled by people texting each other etc.
Terrorists can already hit buildings from the air if they want to. They just have to use private planes. You can load those planes with bombs without anyone checking them.
The problem you miss is who is going to pay more for your product? How do they know in advance it's not expensive crap as opposed to your competitor's cheap crap?
Nowadays a lot of stuff that used to last longer, no longer last as long even though they are the same brand, and sometimes even look the same as the old stuff.
I've a bunch of Byford socks that are still usable after 20 years (they're a bit thinner now, but no holes, and the elastic stuff is still fine), and I've 1 year old Byford socks that are loose due the the elastic band failing. I can understand why cheap socks no longer last 20 years - doesn't really make good business sense (despite supposedly socks going missing after a while).
Not long ago I paid a premium for Hush Puppy formal shoes and they failed early[1] (and I was told by someone that quality has dropped, too bad I wasn't told before I paid for them). So instead of paying a premium, I now buy USD10 shoes that I know won't last, but they cost USD10, so even if they only last 6 months they are cheaper in the long run. Plus they are even more comfortable than the Hush Puppy pair I bought (soft PU is softer than leather).
[1] Heel came off. I glued it back, but some months later the sole split near the ball of my foot.
So what we need to do is throw stuff into really large landfills until one day there's enough to mine (or the tech improves so that it's cheap enough, or things get expensive enough so that we're desperate enough)?
That's a good point too. Each part of the tree is more independent from the rest when compared to the more complex animals.
Chop off a branch, stick it in the ground under favorable conditions and it might become a new tree. It takes amazingly "favorable" conditions to do something similar with humans (aka cloning)...
Well I have HDDs that survive 7000-10000 passes per minute for 3 years, not going to try drowning them though;).
I've seen bad stuff happen with tape at a few different places - e.g. tapes that can only be read by the same drive that wrote them, tape drives that chew up backup tape. Tapes that wear out prematurely. So while HDDs are crap, I don't see tapes being better if you're not going to archive tons of stuff (which is likely to be the case for personal use as per this topic).
There are also portable usb HDDs that are designed to survive dropping (some are even waterproof), and they aren't really that expensive esp when you consider the drive is included with the media;).
Fungi are the ultimate in recyclers. There's a theory that those large coal deposits exist because back then the fungi hadn't evolved to digest dead trees yet.
I think it's more of immune systems than reproductive systems.
Trees do not have "active" immune systems like animals, that cause "transplant rejection". The tree needs leaves and it needs roots, but as long as the leaves do reasonably "leafy" stuff they could be genetically different and the rest of the tree will go on fine. That's why you can often graft the top of one tree species onto the bottom part of another tree.
In contrast it's not trivial to put a related human's kidney into another human. You'd likely still have to suppress the immune system.
It could be because a tree doesn't need as much per in terms of resources (energy etc) per mass/volume, and it doesn't need to move. So some inefficiencies due to "cancer" (strange growths) are less likely to kill the tree. Thus it does not need to kill cancer as urgently.
Whereas strange growths are likely to kill you - once they are large enough so you can't move about, feed or breathe you're going to die.
I don't think LTO drives have a seek time of 15 minutes. Even the older DDS stuff didn't.
But for personal use, I'd still use HDDs instead of tape.
The reason being tape drives are expensive and tapes don't have good wear and tear characteristics - they're good for a few read writes, but not many. Thus they are only good for mass archival - you'd need a lot of stuff to archive for it to be cheaper[1].
Whereas for personal use you can buy 4 x 2TB (or 3TB) drives, do RAID10, and 2-3 years later, add a new NAS with 4 x 6TB (or whatever TB it is by then) drives and copy stuff over.
This is not backup of course, but for personal usage you can use USB portable drives for offsite backups. They are more convenient than tape.
[1] 3TB LTO5 tape costs about USD40. LTO5 tape drive costs about USD1900. 1.6GB LTO4 tape costs about USD25, an LTO4 drive costs about USD900.
As you mention persistence hunting is not really an efficient way of hunting, given most humans don't live solo. And even solo, we should normally be able to outsmart most stuff, and use tools (spear etc).
So I've one theory why humans can run for hours - War. In War, the predator is the same species as the prey. You stand a better chance of surviving if you can run from a group of hostile humans till sun-down or you find a decent hiding place. Evolving to be faster only helps up to a point - after some generations everyone becomes faster too (same species). And I think War was a strong selector back in the bad old days. Genocide, rape, etc.
Of course I'm no expert in this field so I may be wrong. But so many tribes practice war and so few practice persistence hunting. Even chimps have wars.
I said their study was flawed. Perhaps I used a bad example, but the other "ergonomic" studies I saw didn't even provide much proof for why their chair/position is better.
If you bother to read my post, you'd see I'd prefer the "reclined hospital bed position". So far patients still do get bed sores (after very long periods), but they sure don't get injured as rapidly from those beds as office workers get from their crappy office chairs. If they did, the hospitals will get sued even more. So that's my justification. Weak as it is, it seems better than the ones those "experts" give.
Here's what I think - hospital reclined bed position with the fancy anti-bedsore mattresses, if patients can survive that for hours, office workers can. The usual office chairs and fancy "modern ergonomics" are bullshit[1] - it's amazing how after thousands of years of making chairs, decent comfortable ones are still so expensive.
As for that standing fad, there's plenty of evidence that prolonged standing causes problems. Simple rule of thumb, if it hurts don't keep doing it for a long time.
Keep in mind the minimum amount of exercise to maintain reasonable health, supposedly short high intensity exercise is more time efficient. I won't be surprised if it's true - since most animals don't spend hours fighting or running. It's just a short high intense burst up to a max of a few minutes, then a) either they die or they survive to live another day. b) they catch and eat what they are chasing for dinner.
So put it all together and perhaps we should recline while doing "office work", then every now and then walk about for a bit and then do very fast sprints.;)
[1] http://news.bbc.co.uk/2/hi/6187080.stm Seems to imply they only tested up to 135 and said it was least pronounced at 135. While it does show that sitting up straight does put more stress (despite those stupid claims of sitting up straight being good), if they didn't test 180 (or more) then their study is still flawed isn't it?
Actually depending on what the hackers do, changing your password might actually make things worse[1]... Plus Blizzard don't seem to have figured out the details of the hack, so why waste time creating an uberstrong password if they could get hacked again?
BUT if you happen to use the same password in other sites/services, change it at those places.
[1] They might then get the plaintext of your password instead of the "scrambled" version.
Ideally, the authenticating system should hash your reply and compare it to the hashed version from their database just like you would normally. I don't think there's any inherent reason why your security answers need to be human-readable.
They do if the call center person has to type your security answers. With your proposal, if they just type one character differently or add/remove one character the hash will be different.
The difference between security answers and passwords is that the system should be designed to not allow you to do brute forcing on the former.
Uh, dig in a bit? Would also be faster and less problematic than drilling all the way to the center.
It requires much less power to blow something into small bits than it does to move it if the energy is expelled in all directions.
a) Stick a small firecracker to the side of a large rock, and hang the rock on a string. Set off the firecracker, does the rock move slightly? That's deflecting the asteroid.
b) Drill a deep hole into a similar sized rock and put a same strength small firecracker into the hole. Set off the firecracker, does the rock blow up into small bits, or large chunks, or not at all. That's blowing the asteroid to bits.

Has anyone here tried AppHarbor? https://appharbor.com/
For a while they were going on about being "Azure done right" ;).

Wondering how it compares with the latest Azure now...
I think the issue is IF the rates are increasing, then it could mean they are losing control of the mosquitoes and the disease.
A lot of places in the USA aren't very different from Africa. But you bunch aren't dying from as many nasty diseases.
All it takes is for people to screw up big time and one of the diseases could take hold.

No. 80 kg * 12.5mg/kg = 1 gram. Not 1 kg.
So you would have to eat about 2 x 160g tubes of toothpaste.
There might be other stuff in toothpaste that would kill you first.

Even with LTO tape you're still supposed to check for damage due to drops (e.g. someone else dropping them) and not stick damaged ones in drives:

Seems to be about 90 seconds to 3 minutes max (100 seconds for LTO4).

Sure there were, but I think we can ignore those for the topic of discussion.

Wow, do I really have to guide your feeble mind every step of the way? Well too bad, not going to do it for free.

From the summary:
Worse, it appears this data is compiled and stored for up to a year and is disclosed to anyone who asks for it."
If the above is true then anyone including you can build up the database.
So how does this sort of stuff work in the architecture field?
e.g. say you have a team of people designing a new large building with an innovative design.
Actually depending on what the hackers do, changing your password might actually make things worse[1]... Plus Blizzard don't seem to have figured out the details of the hack, so why waste time creating an uberstrong password if they could get hacked again?
BUT if you happen to use the same password in other sites/services, change it at those places.
[1] They might then get the plaintext of your password instead of the "scrambled" version.
So if you ever "click through" or implicitly "accept" an EULA like that it will still apply because it's legal?
This isn't fourth grade, learn to think on a higher level.

If you take the trouble to read the summary it means demand outstrips long term supply (the rate the stuff replenishes).
It does not outstrip short term supply (the rate you can pump water out).
