    "The swaps are available seven days a week from around 9am to 5pm. He fits you into an available time slot. When I called, the swap station was already quite booked for the next couple of weeks."

    This guy has already done his 9th swap:

    This isn't about driverless cars, this is about autopilot. The distinction should be clear by now for any astute observer.

    Funny... how many times has Audi talked about the R8 e-tron before even showing it or shipping it? It isn't even clear now how many if any are shipping. Or the Q6 BEV? Do you feel this way about GM's Bolt? Companies aren't supposed to talk about their upcoming products and features?

  • BlackBerry: Sentiment Has Turned Sour [View article]
    Poppadom,

    Apparently you don't work in IT security.

    There is no way to verify if any vulnerabilities have been exploited unless someone says so or someone stumbles across an already weaponized version. Most of the people that do this have no reason to say so and Blackberry hacks, given the installed base, are not likely widely disseminated. In other words, those that look to exploit these issues are likely to keep it to themselves. The Blackberry consumer user base is small enough that exploits are likely utilized for corporate or international espionage. At this point, Blackberry enjoys the relative obscurity of a small user base like Macs did in the past.

    From an IT security perspective, it doesn't matter if a high vulnerability is weaponized widely or just a few people know how to do it. Further, if someone doesn't patch the vulnerability either by omission by the vendor or by the people in the field, then it's a simple matter of exploit later on when someone is looking to exploit your particular setup.

    Any number of the "hacks" on other platforms are exactly the same situation... vulnerabilities that might be weaponized.

    As far as "No vulnerability has been know to be exploited on BlackBerry" goes, that's definitely false. That's a pretty high barrier:

    http://tinyurl.com/nnr...

    http://tinyurl.com/ps4...

    http://tinyurl.com/7ak...

    Further, the OpenSSL various hacks can easily be exploited on a number of platforms the exact same way. Again, no reason to expect that they weren't utilized.

  • Tesla's Insane Mode Of Pricing [View article]
    Mr. McDade, there is a wealth of interviews and supporting evidence that Mr. Musk has been thinking about green technologies, electric vehicles and the like for many years. Your deliberate closing of your mind from the mounds of evidence portends a lack of research capability. Good luck with your research for stocks.

  • With Android Auto, Google Goes After Tesla's Infotainment Advantage [View article]
    Some point in the future, someone might start to compete with Tesla. Ok.

    Of course, Tesla could also support Android Car and/or Apple's CarPlay. After all, it's just streaming video with some touch screen support. Tesla hasn't seen fit to make it a priority yet as they already have a very functional, but still limited infotainment stack with a gorgeous 17" 1920x1200 touch screen. But with over the air updates and a generic Linux based software stack, they could drop that functionality right in existing vehicles.

  • BlackBerry: Sentiment Has Turned Sour [View article]
    Poppadom wrote, "BB10, never been hacked."

    Blackberry relies on any number of technologies and code implementations throughout their stack just like everyone else. In some areas, they are definitely better at paying attention to security issues.

    But never hacked? All security vulnerabilities are treated as hacks... on publicly released security problems alone, you can refer to CVE's:

    http://1.usa.gov/1Ip8ZBZ

    If you want to count other vendor's vulnerabilities as hacks, then you have to do the same for Blackberry. All the CVE's classified as HIGH can be assumed to be hacks that have allowed devices and/or Blackberry servers to be hacked. MEDIUM ones are more of a maybe, some are denial of service.

    Further, there are any number of design problems with Blackberry's infrastructure including the way the entire security infrastructure is handled in Blackberry messenger.

    Here's the DoD memo:

    http://bit.ly/1GRLlso

    Some more info on derived credentials:
    http://bit.ly/1GRLlsq

    In most enterprises that care about this kind of thing, they implement S/MIME with a digital cert unique to the user deployed by a MDM. They can also deploy a custom cert for web stuff, and they might write custom apps with their additional security baked in.

    Blackberry focuses well on DoD needs, but this is more about focus on a particular client and their particular needs than general technology. Unfortunately for Blackberry, DoD isn't a wild growth target.

  • Why Free And Unlimited Supercharger Access Can Potentially Devastate Tesla [View article]
    People are busy. No reason to give up one of the biggest conveniences of a Model S, which is charging at home. It's cheap enough at home that charging it at a Supercharger is unlikely for most travel. Therefore, the energy utilization rates both reported by Tesla and by owners is less than 5% at Superchargers in aggregate.

    Obviously, in some regions, Superchargers are used for regular charging. However, in many of those places, the actual driving distances are short and therefore the total amount of energy required per vehicle is actually quite small. Also, there is also a lot of public charging available - again, destination charging whether it be at home or at a shopping mall or at work is more convenient than going to a specific location that you otherwise would not.

    Further, the more expensive the electricity, the more it makes sense to utilize solar and possibly Power Pack. Certainly at 40 cents a kWh, solar + batteries comes in cheaper by far. Solar alone is about 16-20 cents a kWh.

    Not reasonable at all to use sub zero for year around range. While 300 watts a mile is too low for the average for northern climates, 400 watts a mile is similarly too high as the average. In northern climates, 350 watts a mile is probably more accurate for your average owner. I can believe the 388 watts/mile for taxi service as was reported by a Dutch Model S Taxi driver due to a higher amount of start/stops.

    And yet.. instead of using the highest value from the chart, (385) you went ahead and chose 500, for, well, no good reason other than exaggeration? This is also under the worst conditions which means to use it as an average across all conditions is also a farce.

    To truly compare against an ICE limo vehicle in the same conditions, try using 10-12 mpg instead as comparison. The EPA rated mileage of most vehicles used for limo services is about 15-17, so then take the weather into account and the result is 10-12 mpg. Not to mention the start/stop fuel wastage as well as the inefficiencies of running the engine in order to get heat while waiting around in the winter. Too much of that waste heat goes out the exhaust.

    500 watts a mile? That's wildly aggressive driving. This is what you get when you have poor research. The report from an actual Schiphol taxi driver corresponds to under 388 watts/mile, including charging losses.

    Also:
    http://bit.ly/1CZqk3K

    Here's another article:

    http://bit.ly/1pipJUq

    That indicates that drivers charge at home, use public charging around town, and has charging at the taxi company offices. The one anecdote in the first link indicated that that particular driver charges at end of day at the depot (company offices).

    The Superchargers supplement all of that. There are only 8 plugs connected to 4 Superchargers, so it can't possibly be providing all the charging for 167 taxis.

    That's definitely not helping, as fuel is a very small part of this company.

  • Tesla: Lack Of Management Focus Remains A Concern [View article]
    So are you equally mad at Ford, GM, Toyota, Nissan, VW, and others that take the same tax breaks and more?

    Nissan has an ATVM loan of $1.45 billion:
    http://1.usa.gov/1TNdyd0

    Ford has an ATVM loan of $5.9 billion:
    http://1.usa.gov/1TNdwSG

    Tesla has paid back their small ATVM loan with interest and pre-payment penalty.

    They all have the exact same incentives and credits for ZEV. Up to them to offer the products to get the incentives.

    They all have the exact same incentives for tax credits at the federal and the state levels. Matter of fact, it is a disadvantage to go first as when the batteries get better, there's less tax credit left. Nissan has outsold Tesla thus far and therefore has more tax credits. GM and Ford have gotten a lot for their PHEVs. Toyota gets all sorts of credit for their Plug in Prius that hardly has any all electric range. That's the real farce.

  • Tesla Bears Fail To Recognize That Tesla Has The Zeitgeist [View article]
    Mark_A,

    Again, not true. Most coal plants can only cycle down so far - usually around 40%, as they can't ramp up fast enough during the day otherwise. There is excess coal being burned every night - charging off of that production does not increase emissions at all. Further, we still do have a lot of nuclear production and hydro is not fully utilized at night either. It will take a lot of EVs to soak up that amount of production.
