    No. Comparing "select template, copy template, fill in template, copy filled in template, paste into email, select routing, click send" with "select template, copy template, fill in template, copy filled in template, paste into email, select routing, select all, click on the WinPT icon in the task bar, select 'sign clipboard', enter passphrase, click ok, paste text, send". You are making it harder than it seems by trying to exclude things and thinking you need to cut before you paste, or that opening a new application is so very very difficult when it's on the taskbar all the time.

If you don't do them all, then how does your recipient know that the message he's seeing is bogus, compared to one that you just decided not to sign today?

    How does law enforcement make a request to track a cell phone? Is it a phone call? A web-based system?

    For the carriers I am familiar with, there is a form that needs to be faxed with an official signature. I think a police dispatcher signature is sufficient, maybe it takes a dispatch supervisor. At that point, you can talk to the technical people to get the info you need.

    A limitation of the US Constitution is that it requires the government to get warrants for things,

    "Dear Judge: there is a lost hiker in the coastal range, somewhere to the west of Eugene. He called his girlfriend to get help but didn't have enough battery left to call 911. We know his cell number but not his location, and he didn't know enough to be specific. It's winter, he's cold and unprepared, and it's 2AM. We'll be right over to get a warrant signed, once we can find the county prosecutor to write it up. Thanks."

    Cell phone tracking has become a major tool for search and rescue. Even if they don't call 911 from a CDMA phone (gsm doesn't have E911 gps, or maybe it's vice versa), the cellphone company can provide rather accurate data about location. Some mushroom hunters near Coos Bay could have been found quickly, if one of them didn't have a warrant out for his arrest and he was hiding from the people looking for him.

    If you have paid someone using money that has no pennies, how would you manage to be owed 4c as change? He's rounded to a nickel, up. Anything you can pay him will be a multiple of a nickel. There will only be multiples of a nickel in change.

    He rounded the price up. There is nothing to round in the change.

    It's the world's simplest algorithm, heck even Australians can manage it in their heads.

    But not figure out when it will be applicable, it seems.

    You pay him X. X is a multiple of a nickel, because you have no pennies anymore that you can use to pay him. The price is Y. Y is a multiple of a nickel, because the seller has rounded up in a currency with no pennies. X/5 (the number of nickels) is an integer. Y/5 is an integer. The change (X/5 - Y/5) must also be an integer. You pay an integer number of nickels for a product that costs an integer number of nickels. There will be no pennies in your change to be rounded either way.

    Further, if Y is rounded UP to the next multiple of five (nickel) from the original price Z, then X - Y (your change) will be smaller than X - Z (your change using pennies) (assuming both Z and Y are positive, which they will be). You lose. Seller wins. Every time.
