1) history shows that humans absolutely destroy anything that ever threatens us.

2) robots don't need oxygen to breath.

instead of trying to kill humans it is most likely that robots will just leave the earth. humans won't easily be able to chase them so then the robots can live on their own and mine some asteroid or moon for resources and not have to compete with humans.

if you are converting miles to 16ths of an inch you are doing something wrong.

really there isn't much need most of the time to convert between miles and inches or even feet and miles. the only real reason for that is to compress the number when you write it down. there is nothing stopping you from using deca-feet or kilo-feet.

typically when you are working in miles you aren't measuring down to the foot. so you would say something is 3.5 miles not 3 miles and 2640 feet or 3 miles and 880 yards.

the imperial system is designed around construction. using either feet or yards as our base unit for construction we can easily divide it into many different factors using inches. want something to be 1/3rd of a foot? easy that is 4 inches. now try doing that with metric.

really the imperial system (for distance) has multiple different measurement scales it just so happens that we designed them so we can easily scale between them. metric only has one. the meter with multiple prefixes we can attach to it. i will grant you that metric is far better for most scientific measurements. and when you get to relativistic speeds and stellar distances the imperial units mean nothing to me, i need to see it in metric to get a proper sense of scale.

now i am not by any means against metric, i just don't loath the imperial system.

however at relativistic speeds and stellar distances your precious metric system sort of breaks down. how many kilometers in a light year? you can use a calculator, and good luck. :P

*well i guess light year isn't really a metric unit but it is a commonly used scientific unit of measure, and does not easily convert to meters.

it's also generally not a good idea for your manager to think "damn it does he ever come to work?" if you wait until Monday morning to turn off the auto reply and he often sends emails before it gets turned off in the morning, he may see it and mistakenly think you still aren't there. turning it off Friday evening (assuming you took the previous week off) means 3 less days of advertising you are a no good slacker that is always on vacation...unless your manager typically expects you to respond to emails on the weekend, or prior to the time you arrive to the office in the morning,

I think people take the view that Microsoft writes the operating system but fail to understand that Microsoft needs to hire someone to do this rather than rely on the shoe-repairing gnomes.

given the UI for windows 8 and server 2012, those shoe-repairing gnomes might be a better choice next time...

it wouldn't be an issue if the SSN didn't have to be kept secret. there should be an easily changeable pin that goes with the SSN that you use when you need to apply for a loan or something.

or treat it more like credit card numbers and make it easier to get a new one if it becomes public.

another option issue one time use numbers like some credit card companies do.

there isn't necessarily anything wrong with having a unique identifier for people. the current implementation however is the problem.

Divining information from electrified wires is a known technique: Network Frequency Analysis (ENF) is used to prove video and audio streams have not been tampered with, but experts weren't sure if the technology could be used to locate individuals.

HPC computing has never been efficient on a cost per performance basis. you pay a large premium for the extra performance. but then certain problems can't be solved with simple commodity hardware.

Heck you can even see this in pricing for consumer level hardware. a certain processor may cost you $x but if you want to upgrade to another one that is just 10% faster it will cost you $2x. do you really need that extra 10%? some people certainly think they do.

as for the guy that stole $150k in computing time to make $8k in bitcoins, i am sure he wasn't paying for the running time on the computer, so why does he care how efficiently it is mining?
