    "The best strategy on those fronts is a habitual reading of clearly-formatted texts..."

    I think that musings found on Slashdot are not prime examples of clearly-formatted texts.

    Really, you must understand that literature in the classical sense of the word accounts for a small percentage of the media that is consumed by a majority of people in the age group you are addressing. It is an entertainment-oriented lot, who find themselves visually stimulated by the products of others' imaginations -- from television to video games to sites like stupidvideos.com -- and have not been brought up in an environment that fosters active imagination. What they have read is by and large a literate nightmare: sites like Slashdot and the 5th grade english teacher's nemesis, the Blog.

    Writing is learned by imitation of other writers -- and you can't imitate the style of an author you've never read. To become a good writer, one must read. One must be stimulated in imagination such that the visual imagery is crafted in the mind of the reader. The good writer writes in such a way as to capitalize on the experiences of the reader; the writer needs only give a minimal amount of description to suggest what the reader must imagine. The reader then fills in the details.

    If your pupils haven't read already, then I'm afraid you have a Quixotian task. If you make them writers in a matter of months when they have no foundation of literature to guide them, it will be a miracle.

    I'll summarize what you just said.

    In the sale of products and services, there are 4 elements that must exist to create a profitable enterprise:

    Provider: This is the individual or corporation intending to make a profit on the distribution of the product or service.
    Customer: The entity that pays money to the Provider in expectation of receiving something beneficial (the "Product") in return.
    Product: The product or service being sold by the Provider to the Customer
    Means of Delivery: How the Product is delivered by the Provider to the Customer.

    First, we'll look at a simple example: milk. The Provider is the dairy. The dairy has a Product, Milk, that they Deliver to you, the Customer via trucks, bottling plants, and stores.

    Secondly, we'll look at a service: monitored backups. The Provider is the monitoring service, the Customer is the business with the data, the Product is the monitoring service, and the Means of Delivery is the monitored backup system.

    Now, let's consider TV. The Provider (obviously) is the television studio. The studio's main objective is to PROFIT. What is the studio's source of revenue? THE ADVERTISER. This makes the advertiser -- not Joe Public -- the Customer. What is the studio selling the advertiser? Not attractive programming, no, they are selling eyeballs. The eyeballs of Joe Public. This makes Joe Public the Product. And how is the Product (Joe Public) delivered to the Customer (the advertiser)? Not by the medium of television, but by the attractive programming. It is the attractive programming that is the Means of Delivery. The medium of television is the infrastructure (roads and highways) that allows the Means of Delivery (trucks) to do the job.

    Really, there is little benefit to video conferencing other than the "coolness" factor. It's helpful when you have a large group of people having a meeting, because then it's easier to tell who's talking -- for one on one it doesn't provide much benefit. About the only 1-1 scenario where a video phone would help is if you are showing off your body (most "webcams" that are pointed at people seem to be pointed at teenagers and perverts). It also provides context in movies so the viewer doesn't get confused -- but that's not real life.

    Most people would rather have a real face-to-face meeting than a virtual one. They also like the freedom a voice-only phone gives them to move about the room or drive down the street -- multitasking. They don't like being chained to a desk where the camera is. I think that no matter how cheap it becomes (and it has become cheap), it will forever be relegated to the fringe element and the boardroom and never be a mainstream household appliance.

  8. Re:the 'market' on Blu-Ray/HD-DVD Talks End · · Score: 4, Informative

    In consumer electronics, there are two factors that generally direct which format becomes standard: time-to-market and licensing.

    The first-to-market standards proposal has a good shot at winning, because by the time other competing proposals get to market, the first one has so much market penetration that nobody wants the second for fear of incompatibility.

    Licensing models that are less restrictive and more open also tend to find favor among consumers. The less cost and hassle the consumer experiences wins product loyalty in the marketplace.

    Consider a few examples:

    VHS vs. Betamax: Sony was first-to-market with Betamax in 1975, followed in 1976 by JVC with the VHS format. Based on time, Betamax should have become the standard for magnetic recording of video. However, Sony made a mistake with licensing: only Sony would produce Betamax tapes and devices. JVC opened up their technology to licensed manufacturers, allowing for competition in the marketplace which drove the prices of VHS far enough below that of Betamax (and increased the features) to influence the marketplace to invest in VHS technology. Because at the time Betamax devices were still expensive, there was little market penetration for JVC to overcome. In summary, the open standard won.

    DVD vs. Divx (not the codec): Does anyone remember this debate? Those who do, remember that these two competing CD-like digital video distribution technologies were in a little war for the consumer's pocketbook. Both technologies came out about the same time, so time-to-market wasn't an issue. The issue was Divx pay-per-view licensing model: instead of buying a video once and wathing it an infinite number of times (as with DVD), the consumer would buy the Divx video fairly cheaply but then pay something every time it is watched. Needless to say, this went over like a fart in church. DVD won based on its superior licensing model.

    AM Stereo: I'm not up on the licensing models or time frame of the competing AM stereo technologies, but they were both late-to-market in relation to standard AM radio. There was already HUGE market penetration of standard AM broadcast equipment and receivers; few people saw benefit in replacing that equipment. Had there been just one proposal for AM Stereo, and had it been completely open, it is still doubtful it would have ever caught on.

    Microsoft vs. Linux (Gates vs. Torvalds):consumer but it poses problems for developers who, for economic reasons, wish to maintain security over their intellectual property. It is for this reason that many hardware manufacturers do not support Linux: their legal departments cannot confidently say that their intellectual property will be protected if they provide Linux drivers for their products. In this regard, Microsoft's licensing model is superior to Linux's for the developer.

    So in the Blu-Ray vs. HD-DVD debate, who will win? Which proposed standard will be first-to-market? Which will have the less-restrictive licensing model? What about the third factor, technical superiority? What about the fourth factor -- does the public even want it (think DAT or video phones)?

  10. The EnergyStar Fallacy on Cutting the Cost of Household Bills? · · Score: 1

    There's a common fallacy when it comes to saving energy: that shutting things off will reduce your home's total energy consumption.

    This is only true when the outside ambient temperature is greater than the inside ambient temperature, and you are wish to maintain the inside temperature.

    Let's consider the light bulb in the stairway that the kids left on. It's probably a 60 watt bulb, maybe there are two of them. So that's 120 watts, but to make the math easier let's assume it's 100 watts. We all agree that incandescent light bulbs are mighty inefficient, maybe 1% light and 99% heat. So really, only 1 watt of electricity is going to provide light, and the other 99% are wasted.

    But wait! Those other 99 watts aren't wasted after all. They are providing heat to your home, meaning your furnace need provide 99 watts less power to maintain the temperature of your home. Because the light is on, the furnace runs less often. The fact that the light bulb is on has ZERO impact on the total energy consumption of the household during the heating season.

    (As a side note, we are really getting 100 watts of heat out of the 100 watt light bulb, because that other 1 watt of visible light decays to infrared energy and therefore becomes heat.)

    Now, it just may be that one watt of heat energy is a lot cheaper to buy in gas form than electric form. If that's the case, then by all means turn stuff off. You won't be saving energy, but you might be saving money. And if it's the summer season, turn stuff off so the house stays cooler and the AC doesn't have to work as hard.

    TURNING STUFF OFF ONLY MAKES A DIFFERENCE IN THE SUMMER.

    '...it's called "intaking more calories than you output."'

    If you are taking in more calories than you use in your daily life, you will continue to gain weight until the energy required to move you around equals your intake. If you have the intake of a hyperactive person and you are sedentary, you will gain weight until your energy use is equal to that of the hyperactive person. To put it another way, it takes twice as much energy for a 160 kg (350lb) person to climb a set of stairs as it does an 80 kg (180 lb) person. If the 80 kg person climbs the stairs twice as often as the 160 kg person, then the smaller person is more likely to maintain that weight.

    On the other hand, if you need to lose weight, you must either decrease your caloric intake to somewhat less than what you require for daily life, or increase your activity so that your requirements are greater than your intake. As a result, your body will start to consume itself. That's right, a diet and exercise program designed to induce weight loss mean that you ARE STARVING.

    Now that sounds pretty bad, to be starving. It is bad, if you don't exercise, too, because your body finds it easier to consume muscle tissue than fatty tissues. I think there's a survival thing, where the body reserves the fat stores for lean times. If you exercise, though, the increased stress on the muscle tissues forces your body to maintain them, overriding the "lean times" survival instinct with a "stress-work" survival instinct and thereby causing consumption of fat.

    So you can modify your diet, or you can increase your activity level, but you'll probably have the best success (and feel a lot better) by doing both. As for modifying the diet, you don't necessarily have to give up chocolate cake and Pepsi; just consume less of it.

    My recommendation for those who want to lose weight? You'll need to gradually change your habits. If you do it all at once, you'll get discouraged and fall off the wagon. Instead, increase your activity. If there's a hill near your house, walk up it once a day (don't run, don't jog), then back down. Don't worry about how long it takes; the benefit is the same whether it takes you ten minutes or an hour. Vertical gain is many times more effective at improving fitness than walking along the flat. After a few weeks, hit the hill twice a day. Gradually increase your activity until you are walking 6-10km (4-6 miles) per day.

    Decrease your intake. Don't give up the pie and ice cream; just skip seconds at dinner. Have a smaller slice of pie, and only one scoop of ice cream. The pleasure is in the flavor, not the filling; savor each bite. It takes a while for your stomach to realize it's full, so by eating slower you'll get that signal before you're stuffed. Stuffing yourself isn't fun, it's painful. Why should you eat 'til it hurts? Over time, by eating less, your stomach will actually shrink, to where you fill 'er up much sooner.

    If you really want to, you can change your snacking habits. Instead of chips or candy, try carrot sticks or fruit slices. (A real orange tastes a thousand times better than those nasty sugar-coated "orange slices" in the candy section of the supermarket.) For a special occasion, go ahead and eat the chocolate bar, but don't waste your money on the cheap stuff. Buy some high quality candy and share it with someone special in a romantic setting. The memories you make from the time you spend will last far longer than the momentary pleasure from a bitter bar of sludge made in Pennsylvania.

They promise 500 writes (as compared to an average of 50 writes with DAT), their "packet technology" provides for error correction and does not depend on a continuous stream of data to efficiently write to tape, and the quality of construction of Exabyte's VXA drives appears to be very high.

    The cost of VXA is very reasonable, especially when compared to technologies like LTO. (With LTO, the cost per gigabyte for the media can be higher than for hard drives.) If reliability is a concern, you're probably comparing to Travan systems, which were just plain evil. (Travail is more like it.)

    While dd WILL make a perfect clone of a system, it is not the ideal solution for cloning systems (especially Windows) BECAUSE it makes perfect clones.

    The problem lies in that for every user, machine, account, group, domain, ENTITY in a Windows environment, there is a globally unique identifier known as a SID. When you clone a machine, you also clone the SID. When you've got two or more machines with the same SID on a network, you WILL have problems. Renaming the machine does not change the machine SID, and Windows knows things more by the SID than by the name. (Think about having two users in your Linux /etc/passwd file with the same UID.)

    Secondly, dd is not ideal because it does a bitwise copy. If you are cloning a badly fragmented disk, your clone will be badly fragmented. You'll also get all the cruft left behind from deleted files. Ghost can do a dd-like bitwise copy, but in its primary mode it only copies the extant files. If you've got a 120GB disk with only 5GB used, dd will copy 120GB of bits whereas Ghost will copy 5GB of files. Think of the time involved. If your new drive/partition is not the same as the old one, you can't reliably use dd.
