  1. Re:Effectiveness on Movement Sensors a Less Invasive Alternative To CCTV · · Score: 1

    There are many places where security cameras are not allowed. In California, state employees cannot be recorded while working as an example. (Fear of having their productivity analyzed) I have seen a couple of data centers with NetBotz cameras that all have to be covered because of this. There are applications, but there are also better approaches.

  2. Smarter Cameras might go farther... on Movement Sensors a Less Invasive Alternative To CCTV · · Score: 1

    It seems more logical to me to let the CCTV cameras dumb-down their output to act as motion sensors capable of discerning color and motion rather than purely using motion sensors. If you want to get an image, you can call up the camera manually and get whatever is live (or less than 5 minutes old). You can then program a system to look for suspicious movement patterns, and grab the video feeds from affected cameras.

    Depending on how aggressive you got with the system, you could even scan for things like cashier fraud without storing all the video.

    But just plain motion sensors are a pain in the ass. There isn't generally good enough field of view data internally for anything but the most basic functions-- occupancy sensors and alarm systems.

  3. Re:Great... on US Cyber Command Wants Greater Attack Mentality · · Score: 1

    It is actually sad what critical systems end up getting connected to the internet for all the wrong reasons.

    Say I develop a SCADA system for a large data center for a major financial institution. It has an IP backbone, and I connect security cameras to that; the backbone is sized about 1,000x what it needs for my bandwidth requirements, so it isn't a problem. The cameras actually provide a support function (call it visual feedback) to the SCADA network, so it is all in the family, right?

    All ethernet ports are located in spaces that require secure access (and happen to house things like EPOs that can take down the facility in one go), and everything is perfectly logical. ...And then something changes. Innocuous changes, like the responsibility for after-hours first response shifting from Security to the NOC. Then everything goes to hell. The Network folks are against stand-alone networks, since they can't send an outbound mail message to their servers. Then, they complain that their management tools can't spot problems on the network. Pretty soon, it is straight on the corporate network...

    Every time I have done a solid SCADA system, this is what ends up happening. Pretty soon, I will just go back to RS-485 networks, which kills me. The only plus I have is that my network is fundamentally more secure than the NetBotz crap that all the IT guys put in without proper security gateways...

  5. Re:Cool air outside doesn't help that much on Iceland Woos Data Centers As Power Costs Soar · · Score: 4, Informative

    While I am no HVAC engineer, I pretend to be one on odd-numbered days.

    Cold climates have several real challenges for data centers. From an HVAC standpoint, there are two general ways to cool a data center in a cold climate-- outside air only and air/water cooling. Air/water systems have drycoolers with glycol kept around 30-40F, and circulate the cold water throughout the building to fan coil units. Minimal outside air is brought in for "fresh air," and must be humidified which generally requires a lot of energy.

    The air-only systems bring in 100% outside air, but must first temper (heat-- to avoid condensation) it and increase the humidity to control static inside the space. Very little pump energy, but the humidification and pre-heat are expensive.

    While it seems trivial to filter out dust, the better air filtration systems increase the pressure drop of the air handling unit, and force you to use a bigger fan. Heat wheels and enthalpy wheels are also an option, but have similar challenges in most real-world situations.

    The biggest challenge with cold climates is making sure the diesel generators start when needed. This alone makes most data center managers skeptical at the prospects of cold-climate data centers.

    For a truly efficient solution, the best approach is likely to be heat removal at the chip level and recovery for other purposes. 100F air isn't very useful, but if you can get 150F water off the chip then that heat can often be reclaimed for some other purpose more effectively. If all else fails, 150F water is pretty easy to cool off in a closed circuit dry cooler no matter what the outside temperature.

    There is also a lot of work going into direct-evaporative cooling solutions (swamp coolers) for data centers, as well as some other non-compressor based cooling systems. Unfortunately, most of these can work very efficiently for 9-10 months a year, and need a separate system to cool for the remainder of the year. Having two systems makes the payback equation often favor the less efficient solution...

  6. Doomed on Will Motorola Rise From the Ashes? · · Score: 1

    While I know that Motorola needs to get a "sink or swim" attitude for the mobile phone business, if I was a MOT shareholder I would want to first kick out management and then determine what needs to be done.

    The real opportunity for the next generation of devices is tighter integration among functions. I would look at the iPhone and iPod Touch as examples of what happens if they draw the line in the sand as proposed. One is a phone, one isn't... but they both benefit from the same user interface and common marketing (to establish brand and look). That same potential may exist between a cell phone and a walkie-talkie or whatever next generation device comes out, but breaking up the businesses will force them to ignore that potential synergy.

    The real reason that Motorola is sucking wind now is that they tied their success to Nextel with the lone exception of the RAZR. They never seemed to listen to customer complaints of their user interface, and people got tired of it and switched to something else. They made a "pretty cool" phone in the Q, but stuck it with Windows Mobile. They aren't doing anything to push the envelope.

  11. Travel Arsenal on Best Technology For Long-Distance Travel? · · Score: 1

    The first priority is to minimize cords and chargers; pick devices that can share the same chargers as much as possible. Blackberrys and Motorola phones both charge from the same mini-usb charger or through the laptop. If I could find a camera that did the same, it would go a long way. Disposable or AA/AAA format rechargables might sound good, but they really are a pain in the ass.

    After you manage that feat, see if you can find a laptop that just needs 24V or 12V external power source that you can find a generic power supply for that can be multi-function in some fashion with easily interchangeable tips will get you that extra distance.

    Skip the dedicated GPS-- unless you will really be out in places that you can die if you don't find your way out. (A guide might actually be a better investment then...)

    Camera... the DSLR is a pain to lug, especially with extra lenses, but the quality is better. Go with a smaller camera (I like the Pentax Optio series) and take more pictures.

    Laptop... if weight *really* matters, as I have said in other similar threads, I used to use a Palm V with an external keyboard. A Nokia 770/800/810 would almost do today, if your storage can be a server elsewhere. (This is often more of a challenge than one would expect.

  12. Re:Cost Analysis on Google Interested in Wireless Bandwidth Balloons · · Score: 3, Informative

    From the WSJ article, the shoebox is $1,500, launch is $50 (they use H2 rather than He), and recovery $100. They pay farmers to launch them and adventurers to recover them, included in that cost. With 5% mortality, the cost per balloon is $225, or cost per year $82k. Since the boxes are so cheap, they can distribute 20-30 to different farmers to launch when requested. The recovery is aided by GPS coordinates, but I will admit it wouldn't be worth $100 to me to go out and find one.

    The coverage should be ~50 mile radius.

    To build a base station to do the same thing you would need at least a 300' mast and microwave links between them, plus you have to lease the ground. I don't think you can pull it off with less than a 3-year payback; you also need more prime airwaves.

  13. Re:Rural area on Google Interested in Wireless Bandwidth Balloons · · Score: 1

    It's actually a pretty ingenious start-up solution.

    Initial costs are minimized by having such a cheap deployment cost. Costs are kept down by limiting the battery needs for the device, letting it drift, and having a practical coverage range. If the marginal cost to launch another balloon is only $225 given launch, recover, and mortality, they can quickly adapt to changing needs. Upgrading the network with new technology is about as easy as it gets... just mail out a new set of shoeboxes!

    Once you start adding complexity to it with solar cells and propulsion, costs can quickly spiral out of control.

    I'm just curious how much bandwidth they can muster out of a system like this...

Border security does little to improve the picture; look how effective it is with the drug trade.

DVI, gigabit Ethernet, 4xUSB, FW, and maybe even an external battery, without relying on a tangle of USB Hub, Ethernet Dongle, Mini-DVI Dongle, etc. Something along the line of the supplemental Sony batteries for their ultraportables.
