  1. I'm allergic to books on Ad-supported Textbooks Are Here · · Score: 1

    Honestly. I have allergies to Spruce/Pine/Fir (SPF) and most softwoods that end up as the pulp feedstock for paper. I'm also allergic to my current residence, which is constructed mostly of SPF. I actively purge dead-tree materials in favor of electronic equivalents. The "textbook" and "newspaper" smells that some people praise are anathema to me. However, putting adverts in reference material is just as bad.

    That said, the college textbook requirements have always been a scam perpetrated by the university(ies) in collusion with the publishers. The university environment is one that isn't subject to free-market forces, and will abuse the students to their tolerance limit. The university can dictate terms. It's in the publisher's best interest to play along. Consider it the price of admission.

    I'm amused at the Rube-Goldbergian prospect of using Solar_cells -> electricity -> batteries -> bulbs -> light to grow plants. Maybe we could add a water wheel and some chipmunks in the path too.

    Seriously, plants already operate off solar ... you'd probably get better overall efficiency using reflectors and light pipes. Of course, you can't grow 24-hours a day that way.

    Staircase power is a bad choice. The circuits are designed to be efficient (cost, installation, materials, etc) for the staircase light load. There isn't going to be a ton of margin left on that circuit. Lighting circuits, in general, aren't designed for larger loads. The 220V HVAC connection is a better choice. I understand that the "growers" aren't the sharpest hammers in the drawer, and don't always have access to better sources ... but you're never going to be able to pull "huge amounts of power" from a stairwell lighting circuit. You'll get a modest amount, but it'll be limited.

  4. Re:Level playing field on Hoboken, NJ vs. Giant Parking Robot · · Score: 1
    I disagree. Patents exist to allow Joe Sixpack (back in the day, that would have been "Jofeph Fix Pence") to create an invention and benefit from it. The big threat is that someone with more money/ifrastructure than you can swoop down and swipe your idea. The "exclusivity" is there to promote development:
    Article 1, Section 8, Clause 8 (the "Intellectual Property Clause" also called the Patent and/or Copyright Clause) of the United States Constitution states, "Congress shall have the Power... To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries."

    The US Constitution doesn't mention Copyright or Patent by name, but includes a section that identifies the need for such structures. If we didn't have this, there would exist an entire subculture of predatory corporations who only existed to swipe the inventions of others. So yes, it's supposed to level the field (i.e. you have an opportnity to create/invent without having to fight the IP-swipers.) Unfortunately, it's being abused right now. The Patent system needs an overhaul pretty desperately.
  5. Turbo Pascal was disruptive on Borland Announces the Return of the Turbo Products, with Video · · Score: 4, Insightful

    Pascal was/is a great learning language. It's not too difficult to comprehend, but it's strong enough that you don't immediately exceed it's capabilities once you "get it."

    Turbo Pascal was a great because a) it was inexpensive compared to everyone else; and b) it compiled soooo much faster than everyone else. The development environment concept was pretty innovative too, and eliminated much of the command line funkiness. Funny, I didn't Turbo Pascal in the press release - Delphi, C++, C#. I guess you could call Delphi "object Pascal" if you wanted to.

    However, this press release stinks of a marketing cash-grab where they try to make a quick buck by squeezing the legacy heritage of a well-known trademark. I just don't see that they're adding any value to the proposition. Some marketroid probably did the math based on "no new development NRE" and was brimming at the huge potential margins on such a re-release (i.e. Margin := (1 - Expenses / Revenue); ). There's competition now, and most machines owned by hobby-programmers and students will cruise through the compilation process fast enough that the "turbo" brand doesn't offer a compelling solution like it used to. There are OSS solutions available, so the "less expensive" compulsion is gone as well. Back in the day (man, y'all are making me feel old ...) the alternative was the Microsoft compiler that was dog slow and required a manual linking step ... from the command line ... both ways.

  7. Oh yes, they have patents on Hoboken, NJ vs. Giant Parking Robot · · Score: 3, Interesting

    The Robotic Parking website has some very agressive language (middle and bottom of page) that summarizes as "You will license this from us." I wouldn't purchase such a thing with these terms. When I purchase an item from the patent holder, I obtain explicit permission to use the item - mainly because I paid the patent holder. A patent is intended to level the playing field with regard to big and small manufacturers, not to allow a manufacturer to extort money from his customers. If I purchase your patented Widget {TM} (c) [Pat. Pend.], once the sale is complete I may grind it into a fine powder should I choose to do so. Your patent does not extend into dictating *how* I may use the product that I now own.

    If the City of Hoboken got a purchase discount in exchange for Robo-Parking getting a piece of the action, that's a completely different contractual arrangement. Regardless, this contract is stinky. The elected officials who signed this turd need to be un-elected (and possibly punished.)

  8. It's about credibility on Wiretapping Charges Dropped · · Score: 2, Insightful

    The police don't really have a choice on this one. They've already acted, and put the now-very-public process in motion.

    They can't admit that they're wrong. That'd destroy their credibility. They're supposed to be "experts" on the law and it's interpretation. If they came out and said "Whups, we screwed up," there'd be formal inquiries and all sorts of hell to pay.

    The case is a loser. If they continue down that road, they make it more public and the damage is worse. The DA recognized that there's no chance they'd be able to convince a jury to convict, simply because the jury is composed of folks just like the defendant. The DA pulled the plug as more of a damage-control reaction than "it's the right thing to do."

    So they've basically pleaded "no contest." They're dropping the charges without admitting any wrongdoing. They're hoping the matter will slide under the carpet as soon as Britney Spears or Mel Gibson is in the headlines again.

    As for "right or wrong," I firmly believe that the police should be under public scrutiny as long as they're acting as an agent of the state. They are acting in the public trust, and consequently *all* of their actions need public exposure and scrutiny. They should expect *zero* privacy while on the job ... that's one of the motivating/correcting forces that keeps them from abusing their position as LawGivers.

    The bank doesn't own your car. You do. The bank has a lien against it. The bank does't want to own your car ... they just want to take it from you when you fail to pay the loan.

    The lien exists such that you can own the car, and such that the county/state/fed government may tax you appropriately (which is actually the reason a lien exists.) The gub'ment wants your money, and they can't take it from *you* by trying to tax a bank located in another state/country. But that a completely different (but related) rant ...

    Ultimately, the publishers wish to control distribution. They make a buck if they do, and get squat if you bypass them. They want to make it illegal to transfer ownership of a work (be it a book or a cd or a DVD) without getting a cut. The states will probably support them because financial transactions involve taxation. The problem arises when your audio CD is conveyed to you as "property." You have certain rights regarding property, and those rights include the ability to transfer title to the property to someone else. Publishers would like nothing better than to convince the gub'ment that the audio CD is merely a container, and the copyright on the information within should devalue the owner's property status to that of licensee (because the container and information are inseparable, or some crap like that.) Subsequently, you will become a felon because you sold your non-transferrable audio CD to someone else. Of course, this cuts both ways, and your momma becomes a felon when she buys you a Metalica CD for your birthday (she bought it, but can't legally transfer title to you because she bought it and the license would be non-transferrable. Right?)

    The **AA-types want "property" status in order to complete the initial sales transaction, but they want your ownership status to magically change to "licensee" at some point when it's financially convenient. They can't have it both ways ... yet. We had huge "civil rights" issues in the 1960s in the US. I expect that the next big social upheaval will be over "information rights."

Sooo, in your "valid scenario" above, do you spend all your time hovering over the phone waiting for the "might be important" calls to show up? Why not?

    If it's truely important, the caller will re-dial after hanging up on your answering machine's greeting. Works fine.

    Honestly, the "what about emergencies" arguement is as badly abused as "think of the children." My telephone is a resource for *my* convenience, paid for by *me.* If someone calls while I'm eating dinner with my family, the call is allowed to roll-over to the answering machine. If there's an immediate call-back, I'll probably interrupt what I'm doing. Somebody screaming into the answering machine in the next room would be a good clue too. Everything else gets done on *my* schedule.

    It used to be that receiving a telephone call was a big deal - think back to the early 1900's. Nobody had phones. If somebody called you, there was probably large expense (money, time, effort) to place the call from the other end. That expectation persists to today, in spite of the ubiquity and low-value of most phone calls. The phone companies go to great lengths to maintain this perception of "high priority interrupt." They're in your face, and they want to stay there (but that's a completely different rant.)

    Think of the children. They're busy eating their dinner and experiencing some family time. Call back later. (To address the original poster: get an answering machine; learn to use it; don't let the phone rule your life.)

They got a hit on a house, backed a van into the garage, and closed the door from the inside. They used a chainsaw to extract the entire doorframe from the garage wall, and had pretty unrestricted access to the house at that point. They took a van's-worth of stuff and left, with nobody in the neighborhood seeing anything out of the ordinary. The cops suspect they used an electric chainsaw powered from the house - less noise that way.

    Man, you're making me feel old ... I've witnessed 40 of those 50 years. BTW, your description of the situaiton as Breach of Contract is very well worded.

    That said, I feel like I'm in the same exact situation. I've expressed my dissatisfaction with the Sonny Bono Indefinite Copyright Extension nastiness. The retro-active part makes me particularly furious ... that's the piece I consider to be the material breach. More specifically, the original copyright terms formed a valid contract - the three requisite parts were satisfied (offer, acceptance, and consideration.) The "consideration" in this case is an exchange of a short-term monopoly for public-domain status at the end of that term. Disregarding the offer and acceptance aspects of the retroactive extension, there's only benefit for the copyright holders and none for the public. The copyright extension act therefore fails the consideration test, and is not a valid contract. The public already had the "revert to public-domain" element in the original contract. The extension offers benefit to the copyright holder in exchange for ... what? (hint: nothing.)

    I've used the term "breach of contract" in many discussions. Is it possible to file a class-action lawsuit against Congress for Breach of Contract?

    I'm quite certain that the lawyers would have a field day with that. The original contract was negotiated by representatives of the people, and I'm also quite certain that they'd argue that the terms of said contract were re-negotiated by representatives of the people. The whole "representation" thing creates a nasty grey area - we citizens aren't allowed to opt-out of laws we don't like.

  22. Re:calculations on Hyperdrive and Space Propulsion · · Score: 1

    Nothing fishy; just math and basic physics. You know the boundary conditions - v(initial) = 0, and v(exit) = 11km/s. With an 11km-long launch tube, you've got a pretty well-defined system. If you start with the easiest scenario - a constant-value acceleration, starting from standstill, you can calculate the necessary equations:

        a = a (which happens to be a constant)
    Integrate to get velocity:
        v = a * t (which happens to be the equation for a line intersecting with [0,0])
    Integrate to get distance:
        d = 1/2 * a * (t^2) (which happens to be a parabola)

    If you have an 11km tube, and you enter it at zero velocity, and exit it at 11km/s, the above equations define the *minimum* acceleration necessary to meet the requirements. If you substitute a more complex acceleration profile and do the integrations, you'll come out with similar equations, but the peak acceleration is going to be higher at some points than with the constant version.

    And the math is just ... math. It doesn't have an opinion. You may not like the answer, but that doesn't make it wrong. The system you asked for - escape velocity at the end of an 11km launch tube, starting at standstill - defines the environment. The math told you what you'd need to do in order to achieve those goals.

    Turn it around. I'll give you some "artistic license," too. I'll allow you to have 100g constant acceleration over the duration of the launch, and make the assumption that we invent some tech that allows hyu-mons to survive the stress. The d=1/2at^2 equation dictates that 11km=1/2(100*9.8m/s/s)(t^2). It'll take 4.738 seconds to traverse the tube. You now know "t", so you can calculate the exit velocity as v = at = (100*9.8)*(4.738) = 4643.24 m/s. Unfortunately, that's not quite LEO orbital velocity (7.5km/s), so you're passengers will need additional protection from the ballistic trajectory (and subsequent re-entry).

    It's not my opinion ... it's math. Embrace the Math, it's powerful stuff. As for the car accelerating to 27m/s in 3 seconds, it's all about horsepower (or kW outside the US.) Using the same equations above, v = at says (27m/s) = a (3s). Solving for acceleration, a = 27/3 = 9m/s/s, or about 1g (not terribly impressive.) Performance cars have upwards of 300hp (220kW) powerplants, which probably isn't "power at the wheel." Another poster indicated the need to have about 12.1GW to put 100kg through your launch tube ... that's 5 orders of magnitude more power required. Nah, the math is consistent.
