The most "efficient" method in terms of customers served per unit time is multiple lines, one behind each register - then there is minimal downtime between customers and the numbers served are maximized, however it has the major disadvantage of not minimizing the time spent in line by each customer - the unlucky ones pick a slow attendant who managed to get all of the slow patrons with special situations that need extra time to serve. The one line feeding separate servers is most fair as everyone goes through the same line and nobody gets stuck waiting for the slow server or stuck behind the slow patrons while being passed by the lucky patrons who got the faster lines. However, the one line has the disadvantage of causing a delay for everyone for each customer as the customer walks to the checkout from the front of the single line. This can be substantive: if the walk is ten seconds and the line is 60 people long, this is 600 seconds, or ten extra minutes you would be standing in line compared to if the walk was instantaneous. The way around this is to have a long line feeding to short lines (even only one patron deep) at each checkout. Yes, people stuck behind a problem patron can sometimes wait a bit longer than they might like, but on average they tend to be better off. I have seen this type of thing work well at customs checkpoints at airports, where there is someone in authority telling people where to go. The difficulty of course is that any of these single line->multiple checkers work well without mechnisms to keep them working - either a machine or a person telling the next in line where to go and ideally watching the whole system to work around individual slowdowns and special cases. It is not very self-organizing.

When liberty itself is feared

Yep, you're right - It's really important for gun nuts to have the liberty to gun down children at school.

Man, nothing makes me angrier than gun-fanatics championing "liberty." You want "liberty?" Go DO SOMETHING to preserve your democracy, to make America better. Buying another Glock has nothing to do with liberty. .

It's fine to do that for gmail or yahoo, Comcast, etc but might not appreciate it if iPhones are sending that information back to apple even if it is never published.

I don't think that anything beyond the "" is going to to Apple, but I suppose if you are worried about anyone knowing what your email address is, then yeah, it might be a concern. Someone posted a link to an RFC of some sort that detailed how mail server settings should be published that could make this type of system unneccessary - too bad that is not more widely implemented.

Summer temperatures up north can still get pretty warm. Bettles AK (on the arctic circle) has high temperates in the summer of at least the low 90s occasionally, and this is warm enough that compined with a sealed car and lots of sun can certainly push the car temperatures up pretty high. Summer days can be very long too.

Well I could always block encrypted traffic and implement introspection rules or allow encrypted traffic and implement MITM. It is my LAN and there is absolutely nothing apple can do about it ;-)

If my phone and Apple's server already have a pre-shared encryption key, how are you going to implement a MITH attack? (or should that be "an MITM attack"? I suppose it depends if you read it as "em-eye-tee-em" or "Man In The Middle".) You can certainly drop the connection, but I don't see how you could read or spoof it.

Same here. I've been using that "feature" to check how long the maid stays when she comes by to do weekly housekeeping.

Now I know how she can afford an iPhone, she charges for 3h but stays 2h!

Untill you knew how long it took her, were you happy with the quality of the cleaning and the price you were paying? If so, try not be be bothered by her "profit margin". If not, renegotiate the fee, or find someone else to do the job.

With all that said, are you paying her a "living wage"? For Alameda County, California that comes out to something like $24/hour for a single adult supporting one child or at least $11.50/hour to support just the working adult.

Of course people working jobs like house cleaning or computer consulting cannot typically get billable hours for 40 hours per week due to scheduling difficulties and travel time, so the hourly rate needs to be higher to account for that, or as your cleaner may attest, the "billing time" might be longer than the "working time". Other ways of offsetting this it to impose time minimums (at least two hours per job) or charge for travel time or distance. Considering that the IRS has a standard car expense of $0.56/mile, if someone is driving 60 mph they are generating an expense of $33.60/hour. Granted, the IRS is very generous on this expense calculation, but the actual expense for most people is probably close to at least half of that.

There are very few people getting rich cleaning houses.

That would require an even bigger violation. They would have to have the client send the actual configuration to Apple as well so they can have the data. Not all businesses would appreciate that.

I'm not so sure - most email providers provide all this information on their web pages anyway. Unless you are suggesting that Apple's mail client is waiting for people to manually set up some email and then sending that information to Apple for use by future users, I don't see any problem for Apple to notice that they are getting lots of requests for email accounts at "" and then someone at Apple looking up setup info for and pushing that data out to users as needed.

While this type of "auto-setup" is extermely useful (especially on iOS where typing stuff and cut/past and switching between the settings and the web-browser are less than ideal), I do wish it was a bit easier to get straight to the "manual" configuration dialogues. For times when I know that the auto-setup is going to do it in a way I do not want, I usually start by entering a bad domain which does not return a useful result and that lets me do the setup completely manually.

The people certainly never requested any of that.

Sure they did. They demanded a warm security blanket be wrapped around them at all times, in exchange for loss of privacy and liberty. No one protested at the state and federal legislatures. No one (other than the Tea Party) dominated primaries to ensure that people that supported beliefs of freedom received party nominations... and on and on.

I realize this is Slashdot, where the edge use-case is required to 'win' every time and defines why anything will fail, but for the sake of argument imagine this: For every given flight where there is one individual so asleep on takeoff and landing as to be nearly comatose, there are 150+ who are awake and listening the instructions. The 'no earphones' rule was made for those, Rip Van Winkles excepted.

And yes, they probably should have woken you up, particularly if you're between someone and an exit door.

The only reason for the ban was RF interference

This is incorrect - It was *a* reason not the *only* reason.

Landing and takeoff are the most dangerous times of the flight. If the flight crew have to should instructions to you they don't want you to have earbuds stuffed in your ears with music drowning out their instructions.
