    Substituting "cameras" for "eyes," why can't a driverless car have all of the above?

  2. Re:Bandiwidth is *free* fallacy.. on ISP To FCC: Using The Internet Is Like Eating Oreos (consumerist.com) · · Score: 1

    Once sufficient bandwidth is in place, it costs an ISP nothing if you're downloading at 1 MB/s or 1 GB/s. Other people may suffer at the hands of your use of the total bandwidth at your area of the Internet...

    And some of them will switch to another broadband ISP if one's available, costing the original ISP a customer and their money.

    So in other words, it costs the ISP more when you're downloading at 1 GB/s than when your network connection is idle.

    Next, at the risk of turning this into an economics lesson, I'd like to focus everyone's attention on the careful way you qualified your statement:

    Once sufficient bandwidth is in place...

    What is "sufficient" bandwidth? To an ISP customer, it might be such abundance that it never slows down during peak periods. In other words, the amount where the marginal revenue from adding more bandwidth is zero because already no customers ever see the network slow down. In other words, where MR = 0 no matter what MC (marginal cost) is.

    But in the real world, at least where a company wants to maximize their profit, they will provide just enough of the product or service that the marginal revenue from increasing it equals the cost of increasing it (MR = MC), because any more would turn from a positive return to a negative return. This is why restaurants tend to fill up once or twice per day or per week. If they didn't, the tables and chairs and floor area that they have to rent or amortize and pay taxes on would go wasted more of the time, meaning that they overbuilt the restaurant. (Don't believe me? Next time you're waiting in line to get into a restaurant, ask to speak the owner and then try to make an economic case for them to expand the dining area. Good luck!)

    Similarly, a network that never sees any slowdown is also overbuilt.

  3. Network consumption is consumption on ISP To FCC: Using The Internet Is Like Eating Oreos (consumerist.com) · · Score: 0

    transmitting data over a network doesn't actually consume anything, now does it?

    A 100 megabit network can only move 100 megabits in a second, so a person moving 100 mbps is consuming the entire network. Nobody else can use the network without the first person reducing their consumption accordingly. Yes, the network will make another 100 megabits available a second from now, just like the Oreo factory will make another Oreo to replace the previous one, but that doesn't mean either bits or Oreos are "unlimited."

  10. Time-of-use data caps make sense... on Netflix Pushes FCC To Crack Down On Data Caps (dslreports.com) · · Score: 2

    ...because people tend to max out their bandwidth all at the same time during the day, creating a headache for network data management. To encourage people to schedule their torrents to throttle back during the day, ISPs should make their data caps only apply during peak usage periods, similar to "unlimited nights and weekends" cell phone plans.

    There's a service called NightShift that helps people watch Netflix on bandwidth-constrained connections like dialup. It works by scheduling downloads to occur overnight so they're ready to watch the next day. Netflix could do something similar to bypass time-of-use data caps. "Do you wish to stream this program now or download to watch later? [Stream] [Download]" Then the ISPs might realize that the data caps don't need to apply to overnight downloads.
