Yes. A lot of Kindle editions sold by Amazon use Kindle-specific digital restrictions management.

But won't the store-bought stuff already be on the network, uploaded by someone who got to the store faster than you?

Shouldn't the web server be submitting messages through TCP port 587 (SMTP message submission with authentication) out to a dedicated mail server?

In theory, it should be possible to adopt good coding practices that leave out all the bad parts of PHP, in much the same way that Douglas Crockford recommends for JavaScript in his book JavaScript: The Good Parts. If you think the PHP interpreter inherently has poor security despite good coding practices, have you tried notifying the operators of Wikipedia?

Trojans are exploits of a human vulnerability. How would you go about patching a system against operator stupidity?

This works if the software is still in print. True, on a server, you're going to want to use software that's still maintained. But there are plenty of video games that have gone out of print.

Could they run on a Mac even if the developer used Windows? Or vice versa?

In theory, a web application that uses HTML5 WebSockets could be as lean as a native client-server app. But in practice, it's not done because it would increase the developers' costs, including cost of providing a fallback for browsers that lack WebSockets, more than it would decrease the cost of providing the service.

One possible excuse is "I would, but I can't afford real estate in the service area of cable or fiber." How would you respond to that?

AOL is the parent company of The Huffington Post. I imagine (or at least I hope) that pulls in more money than the dial-up side of its business.

Who pays for the transition to "the internationally standardized units"? Meters would need to be replaced with pedantically SI-compliant meters. And besides, power in practice is correlated with daylight and climate conditions, which recur on cycles closer to 86,400 seconds and 31,556,952 seconds respectively. These numbers are far from powers of two and thus don't quite fit into the decimal SI. Who pays to teach people to multiply and divide by 86,400 and and 31,556,952 in their heads to estimate energy from power or vice versa over the course of a day or year?

If "elsewhere" also requires reputation, how does a user brand new to file sharing in general obtain his first such files? To compete with the ease of use of Popcorn Time, there has to be a way to bootstrap a new user.

Do lab mice even get names? Or is it just the mice on the "outside", like the fictional Elizabeth Brisby?

I'm interested in how this plays out "reputation based access to files" plays out in practice. How does a new user gain enough reputation to begin to participate?

Someone would have cable Internet because dial-up is unusably slow, fiber to the home is unavailable in his location, DSL is either of the above, satellite and cellular are cost prohibitive with their $5-$10 per GB quota, and moving is also cost prohibitive. Someone would have cable TV if the double play from the local cable company is cheaper than Internet service alone.

The other major providers of multichannel subscription television are DirecTV and Dish Network.
