    To use sudo (superuser do), you have to have an administrative account. Regular users cannot use it. OS X apparently (I haven't taken a look at the actual file) automatically places "Admin" users in the sudoers file:
    sudo allows a permitted user to execute a command as the superuser or another user, as specified in the sudoers file. The real and effective uid and gid are set to match those of the target user as specified in the passwd file (the group vector is also initialized when the target user is not root). By default, sudo requires that users authenticate themselves with a password (NOTE: this is the user's password, not the root password). Once a user has been authenticated, a timestamp is updated and the user may then use sudo without a password for a short period of time (five minutes by default).

    ... is another fine work by the same author. It's not quite as detailed and extensive, but this is caused in part by the "quality" of the source material. I enclose this word in quotes because I'm not saying that Anne McCaffrey doesn't write well; in fact, she's one of my favorite authors. But she was not an academic by training -- in fact, she dabbled in the performing arts before becoming a writer -- so the extensive notes that Tolkien created while working on his series don't exist for the Pern universe. (Tolkien was a linguist, which is part of why there's such polish in that part of the Rings series.)

    Fonstad did a good job anyway, using as much source material as she could find and most likely author interviews as well. The resulting maps are well detailed and wouldn't look out of place in a cartography book.

    Of particular interest to me (a die-hard space buff) was the section that showed Pern from space rather than the Mercator projection maps (which are notorious for distorting polar regions) and the section which depicted the landing craft that the settlers when they arrived from their colony vessels. Interestingly, the design looks like a lengthened Space Shuttle orbiter, which makes sense to a point (why reinvent the wheel?) but isn't what I'd choose for such a job; the Shuttle's not designed to make repeated trips in just a few short days. I would have instead adapted some of the designs I've seen for manned Mars flights. (Hmm, such a thing might prove of interest to Ms. McCaffrey or some of the Pern fan web sites out there. Note to self: Design landing craft.) Oddly, the image in the book is missing any kind of propulsion system... strange for a skilled cartographer to miss that detail, but then again, engineering drawings and maps aren't the same thing.

    (The descriptions of the Shuttle in The White Dragon are well done -- for 1978, three years before Columbia ever flew.)

    I have a copy of this book, acquired from the Sci-Fi Book Club some years ago, but it seems to now be out of print. Expect to pay at least $50 for one; I saw one on Amazon.com (used) going for $100!

    The Buran design was patterned after the US shuttle intentionally. When design work started, the Soviets realized that it would be more efficient to re-use the designs for ours, which were never classified and proven to work since the first tests of an air-dropped full size Orbiter in 1977. Thus, the result was a craft that resembles the Rockwell International design in many ways. (See here for some photos of another Buran test article, this one full-sized, on display in Sydney; an Australian friend donated the photos and is visible in one of them.)

    This page has information about the Buran program in depth, including engineering background and a number of illustrations, including a few showing Buran docked to Mir. This, of course, never came to be following the program's cancellation after a single flight in 1988. The U.S. shuttle did visit in the mid- to late 1990s, however, as a prelude to the ISS program.

    This may be a photo of the model that is on eBay, but I can't be sure. This might be, too -- in fact, the probability is rather high.

    From the site:

    "There was severe criticism of the decision to copy the space shuttle configuration. But earlier studies had considered numerous types of aircraft layouts, vertical takeoff designs, and ground- and sea- launched variants. The NPO Energia engineers could not find any configuration that was objectively better. This only validated the tremendous amount of work done in the US in refining the design. There was no point in picking a different inferior solution just because it was original."
    So there you have it.

  11. The True Importance of the Solar Sail on Solar Sail Fails Again · · Score: 5
    While this mission was not a success in that the spacecraft did not separate from the third stage of the launcher -- currently, it is believed that the separation command was overridden by the control computers due to excessive vibration in the vehicle, which is by design -- it is a success in other, more important ways.

    First, it helps to bring the concept of the solar sail as a valid idea to the public eye. Solar sails have been something of a mainstay in some science fiction series as a way of getting to other planets and have even shown up in some popular sci-fi series (one episode of Deep Space Nine, for instance, showed an old Bajoran solar sail vessel, albeit with far too little sail area to accelerate as "fast" as more serious concepts would). However, other more conventional systems (by far the chemical rocket, but followed to a lesser extent by nuclear rockets (does anyone recall the NERVA program that might have sent humans to Mars by the 1980s?) and ion propulsion: how many of you knew that the term TIE Fighter from Star Wars stands for "Twin Ion Engine"? Star Wars never stated what gas was used in those systems, but the gas that has been used in the Deep Space 1 mission and in the Artemis commercial spacecraft. Now that the Planetary Society, which is a well-respected organization, has attempted to actually fly a solar sail, the public will become aware of the possibility.

    It helps to bring the existence of such organizations into the spotlight as well. The Planetary Society has been active for decades -- it was founded by Carl Sagan -- and there are others, including what is perhaps the best-known of these groups: the National Space Society. Others, far less well known, exist, ranging from fan clubs for shows like Babylon 5 (which I applaud for showing what space exploration will be like in perhaps a few decades once we've gotten the hang of building spacecraft with rotating gravity sections to avoid the problems that long stays in microgravity cause) to other grassroots groups that give more or less anonymously (that is, they don't get press coverage) to serious efforts.

    And it also helps to give people like us the idea that we might eventually actually get to go to space ourselves. If someone can spend $20 million for a ride on a Soyuz capsule, and if a non-profit organization can launch a solar sail, then what could happen in fifty years?

    This was, like Apollo 13, a "successful failure".

  12. Re:Interstellar? on Solar Sail Fails Again · · Score: 3

    Partially true. While it is indeed correct that the "thrust" that a solar sail can take advantage of (photons striking the sail surface) decreases as the vessel moves away from a star (our sun, for instance), one must remember that according to the Laws of Motion, an object that is in motion will remain in motion unless an external force acts on it. This means that even after there is relatively little motive force (photons) to be used to accelerate the craft, it will not decelerate either as it passes through interstellar space. Essentially, there would be no positive or negative acceleration during the cruise phase to another star, but as the craft approached that star, the photons that it emits can be used to slow the craft down -- and final deceleration and orbital entry could be accomplished by nuclear or chemical rockets (or even ion propulsion.)

    It is from an address given at Rice University in Houston (where Mission Control is located) on September 12, 1962.

    Not in the US, you can't special-order a VW.

    VW does not allow customers to order cars from the factory the way they do in Europe. When you "order" a car, your dealer either tries to dealer-trade for it or keeps an eye on what is in the production pipeline and does their best to get that car for you. However, if on the way to your dealership it gets bought by someone else (I've heard stories of them getting bought off the truck at the dealer before the buyer's on the truck's route) or another dealer trades for it before you, you're stuck.

    In Europe, you can specify exactly what is on the car from the ground up, and it is built just for you. You want a 4Motion four-door Golf GTI with HIDs and navigation system? Fine! If you ask for that here, not only are the AWD, GPS, and HID headlamps unavailable, you wouldn't be able to "lock" the car down to yourself. VW also doesn't do European delivery right now ... believe me, I looked into it!

    When I bought my Golf, I originally wanted black. My dealer found a black 2000 four-door GLS with all the options I wanted plus the extra of the Monsoon sound system, in the interior color I wanted. Unfortunately, he said it was sold before he was able to contact the dealer who had it. This can either mean that's what actually happened (VW dealers aren't known for being forthcoming) or the dealer who had it didn't want to trade. Since I had given a list of colors that I wouldn't mind, in my preference order, the sales guy went down the list. On the dealer's other St. Louis lot was a white Golf with black interior, lux package, cold weather package. They simply drove it from one lot to the other -- I had to buy it from that dealership due to the way my car broker works -- and I had my car in about a week or so from when they started looking.

    Turns out that black VWs are a pain to keep clean and scratches show up far more easily. I'm glad now that I got white -- there's not many white Golfs/Jettas on the VW enthusiasts' site I use. I'm somewhat unique. :)

The Golf is also more practical and has more rear-seat headroom because the roof doesn't slope down at the rear as it does on the Jetta.

    In fact, the Golf and Jetta are so closely related that you can switch the front bumper, grille, headlights, hood, and front fenders between a Golf and Jetta and wind up with a pair of "Jolfs" -- a Jetta with a Golf front end and a Golf with a Jetta front end. I've seen it done both ways.

    The US Jetta Wagon is just that -- a Golf Variant with a Jetta nose grafted on it. Why? Because the Jetta is better-known to US buyers and VW reasoned that it would sell better that way.
