    Keyboards plugged in during Windows Installation will be exempt.

    The fake HID keyboard can type YES all day, but since the driver software for the fake HID keyboard WON'T be loaded until the user types YES on an existing keyboard we would be OK.

    This type of attack could be defeated if Windows had a security setting that forced all devices to have a properly signed INF package available before Windows will install any drivers for it. That INF (and signed cataloge file, and possibly driver files) can either be available in Windows update or installed by the end user (from the net, from cd etc.)

    More likely for corporate machines a set of approved device driver files would be pre-installed making it impossible to use any USB device not authorized.

    If Windows does not install drivers for the device it is a useless lump of silicon plugged into your USB port (well it could still be stealing up to 100ma of power.)

    Note that Windows 7 and newer already require a signed driver. But for HID devices Microsoft will use their builtin HID driver (signed by Microsoft) matching by class (HID is a class of devices.) The suggestion is that class matching be disabled and specific matching by vendor and product id be required. That means an INF file with the correct VID/PID be available. And the only way to have that available is with a digital signature.

    I would believe the bandwidth disparity argument if end user connections where also balanced, same upstream and downstream bandwidth.

    If Verizon is selling asymmetric connections to end users then how can those connections generate a balanced load (same up and down)?

    My local cable connection is 75MB/s down and 5MB/s up. And if I try and use a substantial portion of the UP the ability of TCP to pull large amounts of data down suffers.

    Since (well at least for the Los Angeles peering point) the finger is pointed directly at Verizon.

    Level 3 has requested, Verizon has declined, to install additional 10 GB connections to increase bandwidth that is at 100% capacity.

    A very low cost solution to allow traffic that Verizon's customers have requested to transit from Level 3 to Verizon's network.

    I'm zero steps away from saying Verizon needs to provide adequate peering for the services THEIR customers want to use.

    In this case Verizon's customers want Netflix and think they are paying an adequate fee for a high bandwidth (e.g. 75MB) connection that will support a reasonable VOD stream.

    Verizon needs to provide that service. Netflix needs to pay to get the bits TO the peer point. Verizon's customers need to pay to get the bits FROM the peer point.

    At some point an enterprising class action legal firm is going to crunch the numbers on behalf of Verizon's customers. It won't be Netflix they will go after.

    This is exactly what Level 3 claims.

    http://blog.level3.com/global-...

    The above uses the Los Angeles interconnect as an example. Four 10-GB ethernet connections between Level 3 and Verizon and they are saturated.

    Level 3 wants to add additional 10-GB connections (and even offered to buy the router cards, cable and do the install :-) ). Verizon refuses.

    "So in fact, we could fix this congestion in about five minutes simply by connecting up more 10Gbps ports on those routers. Simple. Something we’ve been asking Verizon to do for many, many months, and something other providers regularly do in similar circumstances. But Verizon has refused. So Verizon, not Level 3 or Netflix, causes the congestion."

    It *could* be that Verizon realizes that currently, as configured, the Verizon network is running nicely (as the nice diagram shows). And that doubling the amount of traffic by doubling the interconnect to Level 3 (and thereby satisfying their customers demand for Netflix VOD) would cause a meltdown.

    But in any respect, Verizon is selling a service and not providing it. Netflix is paying for transit TO Verizon and Verizon's customers are paying for transit (to Verizon) for transit from Level 3. Verizon needs to charge their customes what they need to provide the service.

  8. Re:not likely on Cable Companies: We're Afraid Netflix Will Demand Payment From ISPs · · Score: 1

    When the first question your users ask stops being "Can I watch Netflix?" then you can charge the ones that do ask it more for the exorbitant service level they are demanding.

    Until then, since it IS the first question most of your users are probably asking you need to suck it up and provide the service even if it means charging more. If your ARE the only provider because of the small area you are in then your users will either pay or give up netflix.

  9. Municipal collection of fines is the problem. on Chicago Red Light Cameras Issue Thousands of Bogus Tickets · · Score: 1

    If you allow municipalities to a) collect the fines and b) game the system be prepared for problems.

    In BC it is mostly the opposite. Ticketing and cost of enforcement IS covered by the municipalities (who fund the police) but the fines go to the provincial government. So increased enforcement (which may be a good thing) will cost the municipality more. And if they are willing to fund that then good for them. But they won't increase their revenues. And in fact may increase their policing costs if the ticketing officers have to attend court more often to defend the tickets they write.

    Gaming the system (short Yellow lights for example) will result in higher revenue to the province. But more complaints to the municipality. So mostly doesn't happen.

    While the province can (to some extent) game the system by trying to introduce things like traffic cameras, in practice they are more sensitive overall to campaigns to complain about them. So they move slower with more political caution.

    We also have a provincially mandated insurance (for which there are lots of pro's and con's...) One of the side effects is that intersections that are expensive (i.e. high number of accidents) to the Insurance company will get money flowing from there back to the municipality to improve it. E.g. better signals, barriers etc. The point is that money to improve safety may be less than paying out for accidents. They also will make suggestions back to the city engineering department WRT to things like signal timing which will help reduce accidents.

  10. Re:What of the downstream bandwidth usage? on Verizon's Accidental Mea Culpa · · Score: 1

    Its quite possible that upgrading the interconnect would all of a sudden cause Verizons network to melt down (i.e. push their overall utilization from a nice manageable number to something unmanageable.)

    But if that is true it simply means Verizon is not charging THEIR customers enough to provide THEIR customers with the traffic that THEIR customers have requested.

    Yes it is Netflix that is the source of the traffic. But it is Verizon CUSTOMERS that are requesting that traffic based on representations made by Verizon (pay this much and we will allow you to download XXMbits/s.) If Verizon cannot provide that download then they are not doing the job they are being PAID to do.

  11. Re:Help me understand on Verizon's Accidental Mea Culpa · · Score: 1

    No, on the Internet you pay for YOUR traffic period to YOUR provider.

    Verizon needs to charge THEIR customers for all costs. Level 3 needs to charge their customers (Netflix in this case) for their costs.

    The problem is that the new model of watching streaming video requiring larger bandwidth and providers like Verizon are looking for ways to pay for that infrastructure. Charging additional fee's to their customers is difficult (image for a second if Verizon tried to market broadband connections for $X/month or 2x$X/month if you want to stream video... )

    So instead they try and bully the other end (Netflix being the easy target with the deepest pockets) into kicking some money their way.

    Funny you should mention maintenance. Presumably the smaller generators on wind turbines will last longer with less maintenance. Especially since any maintenance that is required is distributed across a larger number of remote points (some in the ocean) and many feet in the air.

    We have a gas fired plant locally that used to have yearly tours (sadly suspended after 9/11). Highly efficient and large turbines, but at the expense of frequent (well once every year or two if I recall) maintenance and overhauls. But large power plants have built in cranes to lift the turbines out of their cradles and move them to the attached tool shop that has all of the required tools and mechanics to rebuild them.

    Wind turbines require that the mechanics with their tools get transported to the site, lifted in the air and then work in cramped and dangerous conditions. Of course if you are looking for a challenging and probably rewarding (financially) career the Wind Farm service industry is hiring. There are a lot of Wind Turbines coming off warranty.

    Because most public transportation is less efficient than autonomous cars.

    The exceptions are very high bandwidth routes carrying a consistently high amount of riders.

    Most of the time for most routes you have large, expensive, low gas mileage vehicles running mostly at a loss.

    Autonomous cars will be able to work efficiently in a dense configuration where they can operate very close together achieving almost the equivalent of the best of mass transportation.

    And for the rest of the time (probably > two thirds) they are simply more efficient than pretty much any other alternative.

    Autonomous cars also optimize for peoples time. The latency of your travel (time to get from a to b) will be lower. Since you don't have to walk to the closest bus stop, then take the local feeder bus to mass transit, then switch and wait for that, etc. You get picked up at home, and read your paper or work on your laptop until it drops you off at work.

    Finally, building this out doesn't require mega-investments by local or state or federal governments. Since autonomous vehicles will re-use the existing road network (and more efficiently at that) multi-billion dollar investments in public transit lines won't be needed. Just encourage adoption of autonomous vehicles. As the old fleet ages out and the new one rolls out it becomes more efficient in its use of the road network.
