  1. Cost used to keep the problem in check. on Two New Fed GPS Trackers Found On SUV · · Score: 1

    The level of cost involved used to provide a limit on the intrusiveness of the search. Police used to need to provide at least 6+ officers (2 on 8 hour shifts) to watch an individual, that means that following someone involves substantial cost to the department. The cost itself provided a check on the intrusion.

    Using a tracker changes that entirely. The police can quickly check many, many trackers from a central location. They don't need to invest 6+ officers to each individual, it's 6+ suspects per officer! All of a sudden, large scale intrusion is cheap and the limit is no longer present.

    That's the point you need the courts to step in and put limits in place.

  2. It's not just about your salary. on Federal Contractors Are $600 Screwdrivers · · Score: 1

    It's called a Loaded Labour Cost. Back the last time I had to deal with this (back in the 90's), the LLC for a staff member, regardless of salary ended up being around $150k/year. That's how much it cost the _employer_ to have you in a seat, pretty much regardless of your salary.

    So, the federal government can either pay that themselves and have a full time employee on their staff, or they can pay that plus a markup and have a contractor they can get rid of whenever they want.

    The contractor is typically better if only for the ease of downsizing.

  3. Internet Traffic down 10%. on P2P Traffic Drops 10% After New NZ Law · · Score: 2

    It's the _total_ international internet traffic which is down 10%. Given that P2P forms 30-50% of an ISPs traffic (supposedly), that means that there has been a 20-33% drop in P2P traffic. So, while it sounds small, it is actually a large difference to P2P, all without a single $25 letter being sent out.

  4. Not worth it to Google. on Why No War Over MS's Android Patent Shakedown? · · Score: 1

    Android is a loss leader, and not worth a lot to Google. Google's patents are probably in their core business, search and advertising. Since a lawsuit would result in settlement and cross licensing, Google's patents are worth a lot more for keeping Microsoft out of that core business than saving HTC $5-15 per handset.

  5. Re:QA - Microsoft is really to blame. on The Most Dangerous Programming Mistakes · · Score: 1

    Because vectors can't be initialized from initializer lists. At least, not until C++0x:

    std::vector v = { "xyzzy", "plugh", "abracadabra" };

    char *foo[] = { "xyzzy", "plugh", "abracadabra" };

    Considering we've seen a story about how everyone is using the same password everywhere, and how Sony got hacked again , exposing even more passwords, is it any surprise that a number of people are having their iTunes and PayPal accounts attacked and drained to buy game gold?

    iTunes and PayPal are pretty huge targets, but who'd attack a single game if they had access to the back end?

  8. 1.2 million, actually. on Google's Driverless Car and the Logic of Safety · · Score: 4, Informative

    http://en.wikipedia.org/wiki/Traffic_collision

    Worldwide it was estimated in 2004 that 1.2 million people were killed (2.2% of all deaths) and 50 million more were injured in motor vehicle collisions.[1][39] India leads with 105,000 traffic deaths in a year, compared with over 96,000 in China.[40] This makes motor vehicle collisions the leading cause of injury death among children worldwide 10 – 19 years old (260,000 children die a year, 10 million are injured) [41] and the sixth leading preventable cause of death in the United States[42] (45,800 people died and 2.4 million were injured in 2005).[43] In Canada they are the cause of 48% of severe injuries.[44]

  10. Isn't it better with traditional electrolysis? on Artificial Leaf Could Provide Cheap Energy · · Score: 2

    According to wikipedia, http://en.wikipedia.org/wiki/Electrolysis_of_water , traditional electrolysis is 50-80% efficient, and solar cells are ~20%.

    http://en.wikipedia.org/wiki/Solar_cell_efficiency

    Therefore, the efficiency of using the solar panel to power electrolysis would be .2*.5 -> .2*.8 = 10% -> 16%, wouldn't it?

    So, unless there's a pretty substantial price benefit to the cell, where's the benefit?

  11. Re:The irony on German Politician Demonstrates Extent of Cellphone Location Tracking · · Score: 2

    They didn't track the phone in this case either. They recorded the cell sites the SIM card was connected to when the device performed an action which would attract a charge. Extremely different things. Specifically, it is the lat/long/antenna of the cell site which is recorded, not the device. The device can actually be several km away, or even using a different SIM.

    Carriers can mark a phone as "stolen". Once you do that, then that _device_ (separate from the SIM) will be barred from the network, along with a tonne of other international networks. However, they still don't track the device.

    They can track it, but only at the request of the police, and it will typically require radiolocation using several different base stations. Sometimes they use A-GPS on the phone. However, they will only do this at the request of the police, and typically only for a 911 call.

  12. Re:I have news! on German Politician Demonstrates Extent of Cellphone Location Tracking · · Score: 1

    The cell site's lat/long is public information. :) http://www.sitefinder.ofcom.org.uk/ (UK) http://emf2.bundesnetzagentur.de/ (Germany)

    The cell site used for the call is needed so that when there is a disagreement, as in "I wasn't in that city, there's no way I could have made that call", they can provide all of the information needed to resolve the problem, such as showing that you were registered in another city entirely at that time.

    Additionally, it seems they've got legislated data retention rules, but they have typically been based around the existing retention policies the carriers have in order to avoid having to pay the carriers (like the US govt pays carriers for legal intercept).

    http://en.wikipedia.org/wiki/Telecommunications_data_retention

    In other words, cell towers aren't secret, and if you don't want to have your data retained, talk to the government, not the carriers.

    I replied too quickly.

    1) They keep 6 months because that's how long you have to object to the bill.
    2) Billing isn't keeping the lat/long of the phone, it's keeping the lat/long of the cell site, otherwise, it wouldn't be a blob with a direction on the map, it would be a point with a radius. It's the cell site's lat+long and which antenna (direction) is seeing the phone.

    The 6 months is because that's the length of time you have to object to the bill.

  15. It's about the Error Rate. on 'Pruned' Microchips Twice As Fast and Efficient · · Score: 1

    The key part they are removing is error detection and correction. They are creating chips which have an ~8% chance of producing an incorrect result. Supposedly hearing aids will accept a 10% error rate, so it is a good trade off.

    These aren't "redundant" parts, they're parts which prevent errors from happening. It's just that in some applications they don't care about errors.

    It's like looking at the various floating point bugs and going, "meh, close enough". Sucks for a spreadsheet, but if all you care about is integers 0-10, you probably aren't going to notice.

    Here's the actual press release:
    http://www.media.rice.edu/media/NewsBot.asp?MODE=VIEW&ID=15497&SnID=154992879

    "Inexact Hardware" seems to be the new term. Since they mention hearing aids, it seems to be that it's bringing the fuzziness of analog back into the digital world.

    Except that pure aggregations of facts don't have legal protection in the US. They do in other locations, but not the US. Otherwise, there would be a lot of fights over sports scores, tv schedules and phone books, like we have in the UK, NZ and Australia.

    Actually, you are charged for the entire call, that's why most calls have a "X for the first minute, Y for each additional minute, with a minimum of 60s, and billed in 6s increments".

  19. Re:Email should cost one penny per message on Germany Builds Encrypted, Identity-Confirmed Email · · Score: 1

    I agree with you there are better things than charging a penny. We can already see what happens when you do with SMS and VoIP.

    For example, people are hacking VoIP lines and then making fraudulent calls to numbers with large termination rates. The guy at the other end gets his cut and disappears.

    People are also attacking smartphones and doing similar things - signing up for premium SMS services, etc.

    However, we already do have financial systems which are prepared to handle billions of one penny transactions every day - the phone network does this already. It's expensive, but it does already happen.

  20. As much about the UI as anything else. on Why Digital Newsstands Stink · · Score: 1

    Magazines are very, very random access. When I read a magazine, I rarely start at the ToC. I'll flip through the magazine, stopping at a picture that interests me, a title that interests me, or something else. Heck, I tend to look at the advertisements before I look at the ToC!

    It might be construed to say that PC players are more team focused, willing to do things other than shoot the enemy.

    Of course, it is just as possible that someone's programmed a bot on the PC version and the _bot_ is doing the running around, or that the PC players play 10 hours vs the console gamer's 1, or some other difference between the platforms.

    It most certainly isn't a "natural monopoly".

    Here in Wellington, New Zealand, I've got 2 physical broadband cables (DSL and cable) to my house (one at 20mbps, one at 15mbps), 3 separate mobile networks (2 with "broadband" 2mbps+), and plans for a third, fiber connection (100mbps+). I've even got power companies pulling fiber down the street to build a parallel FTTN network so that they can compete on the backhaul business. That's in a middle class suburb. Downtown, there's already a fiber provider in addition to all of the other groups - including the bidding for a second fiber network.

    There is most certainly not a natural monopoly. We're not at the point where all bits are the same, and there is competitive advantage to be had by stringing your own wire.
