  1. Re:Fire Protection System on A Look Inside the NCSA · · Score: 1

    Uhm, go back and RTFA. No Halon system is used, a standard water sprinkler system is used. However, the one failsafe noted was that a smoke detector also had to activate in addtion to the heat fusible link in the sprinkler heads before torrents of water were released. So, you need both an indication of smoke AND excessive heat for things to start getting wet.

  2. Hardly. on Bank on Your Cell Phone · · Score: 1

    It's just another long-standing technology being talked up as the big players get in on the action. I have Etrade Bank as one of my banks. I could do essentially all of the normal transactions on my handset (i.e. transfers, bill pay, trades, cut and mail checks, etc.) back in 2000. This was through Spint PCS, using their Vision internet service, on a web enabled handset (NOT a smart phone). This was back in the days when the handset displays were monochrome and essentially graphic-free. One small wonder was that despite the crude interface (at the time), the handset supported 128 bit SSL and sent/received the data using it when accessing secure sites (A letter "P" would be displayed on the top, next to the other handset icons).

    Really, this isn't anything new. It's just being passed as news as the big banks now realize that enough of their market base is technologically adept and accepting of having this kind of banking access available that it is advantageous for them to offer it.

    As for the security, it's essentially as secure as doing banking online and arguably more secure than using a public WiFi connection. Its biggest security weakness, like everything else, is the human operator.

  3. Re:One problem. on Congress Considering More Low Power FM Stations · · Score: 2, Informative

    You are likely thinking of television broadcasting. The FCC has slated February 17, 2009, though considering that the deadline had been pushed back several times previously, it would not surprise me if this gets pushed out again.

    In band on channel (IBOC) digital radio broadcasting is already emerging in the larger markets. Basically, you can get a digital receiver and listen to your favorite radio station play all its programming, commercials and all, in CD quality audio. The only cost is the receiver. At this point, there is no firm date for phasing out FM (or AM) radio as we know it, just the addition of digital IBOC, which are usually simulcasts of the analog programming.

  4. Fry things? Uhm No. on New WiFi Link Distance Record · · Score: 1

    (the presentation also mentions 100mW on one of the "background" slides).
    Based on that, I'd say the answer to your question is "none whatsoever".

    Exactly.

    What people are not understanding is that there is a BIG difference between peak envelope power (PEP) and effective radiated power (ERP). Bigger antennas and stacked arrays allow you get uber amounts of gain in signal. Instead of cranking the power output up, you focus it instead. Basically it's like adding more lenses and mirrors to an optical system to get an ever increasing focused beam of light from an incoherent light source (i.e. light bulb).

    So, instead of spraying 100mW in an essentially omnidirectional pattern like the little rubber antennas on the back of your wireless router do, they focused it as much as possible towards the other end of the link. The optical analogy here is a lighthouse with its huge fresnel lens. A moddest light behind such a lens looks quite bright from several miles away as result.

    Then, with essentially nothing in the way, the only loses left to contend with are atmospheric absorbtion and scattering. Get up into that higher altitude air that has less water vapor and dust and you've got even less atmospheric loss working in your favor.

  5. Farm direct to Grocery Store? Not likely. on Vertical Farming · · Score: 1

    You raise a valid point with the transportation. While the idea focuses on urban production of food, it does leave quite a bit out on the processing of this food. People forget that it is rare for farmed products to end up directly on grocery shelves, even natural and organic products. Most foodstuffs have to go through some type of processing, if not a wholesaler of some kind.

    So, some additional questions to raise are:

    1. Will such a building house the appropriate food processing equipment for its output? If it's vegetables, we're talking machinery/personnel to wash, clean, peel, cut vegetables. Then, if it's not destined for fresh sale, there's equipment for canning or freezing.
    2. If there's small livestock involved, then there's meat processing involved, which gets even more intracate. Will the whole myriad of by-products be converted into something useable on site, or will it get shipped off to some other rendering facility?
    3. Specialization usually results in more efficient output, which in turn is more profitable. It would be likely that each structure will focus on only several types of crops, at most, and rotate through these. Certainly, you'd never get far with a store on the ground floor that sold exclusively carrots for a couple of months, then peas for another couple of months, etc. There still would have to be packaging, wholesaling and distribution, but to what extent? The only advantage is that the transport distances, in theory would be less.
    4. Will these structures grow things hydroponically, or are we now going to truck in huge amounts of dirt and soil enhancers on a semiregular basis? Yes, there are bugs, pests and blight out in the open, but there are also a lot of other naturally occuring things that are benefical, if not necessary for crops that would also need to be artificially induced.

    I guess I look at this and think of Biosphere II in some respect. It taught us that there's a lot more things to consider besides water and sunlight to keep things somewhat balanced out in order to work properly. Looks like a lot of imagination and creativity on the part of the architectural folks, but a bit light on input from the agricultural and food industry people, at least at this point.

  8. Economics and Physics on Verizon Accused of Slighting Copper Infrastructure · · Score: 1

    Each of these wireless devices will likely cost several times the length of copper/fiber that they would be replacing. The maintenance costs would be astronomical. Despite semiconductors having a nearly indefinite lifetime, batteries...even the best rechargable ones available, still wear out. Also, what you'd save in a PC by decreasing the cost of copper would also be offset several times by the increasing cost of chip grade silicon, which would be in higher demand to manufacture the electronics for these wireless boxes, including the solar panels used to power them.

    Costs aside, the amount of bandwidth that you would need to do this would quickly far exceed the available "open air" bandwidth available to you. Yes, you can shove uber amounts of data in high concentrations through the air using DSS or OFDM, but there's still a limit. Within the confines of a fiber or cable, you can have essentially a whole band of RF spectrum available, and duplicate it again and again in each adjacent run of cable/fiber.

    Wireless is great, but it has its place in communications technology. Its uses are nearly limitless, but so are its misuses.

    I suppose that's one possibility. That would make for a lot of scanners in one area puking data at an AP.

Why not use cell phone signals on maybe several dozen micro cell sites on campus instead? As a bonus, handled call volume increases and you can get the cell companies to help subsidize the cost...and manage the user database, too.

    Well, the rising price of petroleum products is certainly having an impact on the costs involved with producing corn, but it really doesn't affect how much corn is produced (i.e. supply of corn), so the price of corn isn't driven too much by this.

    Escalating petroleum costs cut into the farmer's profit margin, increasing demand for corn raises the price of corn.

  23. Let's not forget... on Ethanol Demand Is Boosting Food Prices Worldwide · · Score: 4, Interesting

    ...that most fertilizers and pesticides applied to corn are derived from petroleum bases. Farming equipment also uses diesel/gasoline during the planting, cultivating and harvesting of corn. Adding to this, natural gas and propane are commonly used to run corn dryers used to reduce the moisture content of the harvested corn. At one point in 2005, the cost of the fuel for these dryers was more than the revenue produced from the corn itself, making it a wash to even bring the corn to market.

    Sure, the price of corn is being driven up by its use for ethanol production, but let's not forget that the cost of growing corn has risen sharply as well in recent years, mostly due to the rising price of petroleum based products.
