  2. Nobody knows about portability... yet on Verizon Drops Opposition To Cell-Number Portability · · Score: 4, Interesting

    I've been reasonably happy with Verizon -- I started out with PrimeCo (Dallas), and was expecting the worst when the former GTE took over (having had bad technical experiences with GTE as a local telco).

    I was pretty peeved last year, though. I wanted to upgrade my wife's phone to a BREW-enabled handset (for Christmas), but my contract wasn't close enough to expiration. I spent quite a while talking to customer service reps and told them that as soon as Number Portability came in November 2003, I was outta there.

    The rep's response was, "What's 'Number Portability'?"

    I suspect that this issue is way below Jo(e) Consumer's radar screen... especially if the carriers' own reps don't yet have a scripted answer to the concept. But that won't last long! By making a U-Turn on the portability issue, Verizon is now poised to spend the next five months "educating" the consumer about their upcoming portability rights... regardless of whether their competitors are on board.

    Imagine the buzz to be generated by a full-page ad from Verizon: Cingular, Sprint, and AT&T want to lock you in. Verizon is fighting to set you free. For once, good business sense happens to be on the right side of the debate.

    By the way, I'm over my tiff with Verizon. I ended up upgrading (with a a cheapie phone) when the contract expired, so I'm with 'em another couple of years, come hell or high water.

    Now read that last sentence again.

    Maybe I'm letting paranoia run loose, but there are more than a few folks in industry that would also like to keep those kiddies off the 'net, raise the bar, have an Internet that is "more useful everyday," as Bill would say. The net effect, though, is to remove the internet gadflies that make the 'net such a democratizing medium.

    The web's success isn't due to the Microsofts and the AOLs -- it's the little guys like me and you who rub the fat cats the wrong way.

    With "high-tech companies... key to the project's success" (and Intel and HP specifically mentioned), I'm afraid their goal is to make the 'net better for those high-tech companies... and to leave the rest of the masses out of the "New Internet".

    Not to become a conspiracy nut myself, but there are a couple of big problems with this defense:

    One: There are a bazillion (I counted) satellites returning imagery, and probably not a bazillion folks to look over all the images before they're released -- especially not in a 24-hour timeframe.

    Two: The withholding of any particular image or set of images is an immediate sign that the image contained useful information.

    Assuming this satellite's data was discovered to contain militarily (or commercially!) useful information, the only way to keep both the imagery and its location secret would be to make all imagery unavailable for some reason.

Despite being in the airline reservations industry -- home of some of the biggest iron of all -- her skills and experience were held in less and less esteem as client-server and GUI became the buzzwords.

But I think the pile of BFD's on the ruins of the department store's electronics counter shows the problem: people (that is, the mindless herd, not we the enlightened) can't handle cognitive dissonance.

    Conker, the main character, is terribly cute. He curses and fights with a singing monster named the Great Mighty Poo.

    The game is cute and gameplay is intuitive and fun. One scene involves enticing a big breasted sunflower into intimate relations with a drunken king bee.
    TILT!

    Faced with this situation, Nintendo took what I suppose was the only logical path: they sold one of their hottest developer groups to rival Microsoft.

    It was interesting to me that BFD was one of the last N-64 games... one review I read described it as "the last must-have N-64 game." I saw a kid-friendly Game Boy game featuring Conker the Squirrel at Blockbuster, but didn't rent it... what would be the point? That character is indelibly linked, in my mind, to the Song of the Great Mighty Poo.

    So it wasn't too huge a surprise to me when I read the news that Microsoft had bought Rare from Nintendo. I don't know how Rare managed to get Conker out Nintendo's door, but I'm guessing that someone wasn't too happy about it.

    I sure wouldn't want to buy anything from the Redmond Empire... but if BFD-2 comes out for X-Box, I may have to put my moral compass back in the box. That said, I like the idea that I can turn to Nintendo for kid-friendly games that -- hopefully -- won't put the adults to sleep.

    SRC III Construction
    By: Nick Anderson

    Part I: Altimeter and Fins (11/12/02)

    Nick and Jeff worked on testing out the altimeter (here) and then moved onto making the fins. We laminated 1/16" balsa wood with West Systems Epoxy and 3oz fiber glass on both sides. The wood was then covered in wax paper and pressed with heavy steel plates. We were left with extremely strong, light weight and thin material that we cut into fins. The pressing helped reduced the ammount of excess epoxy in the fins, and also compacted the fiberglass to the balsa well.

    Finished piece of fin material
    Piece is very thin and strong

    This technique will also be used for construction of centering rings.

    Part II: Carbon Tube Construction (11/14/02)

    Peter, Jeff, and Nick went over to Alex M's and constructed an additional carbon fiber tube. We now have 3 lengths of 2.1 (54mm) x 16 in composite tubing. We choose to use this tubing because it offered us very lightweight tubing, with minimal weight.

    Examples:
    16' piece of phenolic tubing: 124g
    16' piece of Carbon Fiber tubing: 60g

    (These carbon tubes here were our first try, the next tubes will hopefully be lighter.)

    These extreme weight savings will allow us to fly on smaller motors. The small motor we use, the cheaper it is, and generally the more available they will be. We are hoping that we may be able to use Estes's Ds and Es for propulsion, as they are cheap. Aerotech motors are also starting to get pretty hard to find around here...

    Jeff and Peter used their math skills to figure out how much carbon cloth we would need, while Alex and Nick prepared the carbon cloth for cutting. We were using a Aerotech K700 casing wrapped in wax paper for a mandrel. After cutting the cloth, Alex applied West Systems epoxy to the mandrel, while Jeff and Peter wrapped and wetted the cloth on the mandrel. Significant problems were encountered at the end, when a large air bubble was found and Nick foolishly unwrapped the tube. Eventually it got all fixed up.

    The mandrel was then wrapped in heat shrink tape, and Alex used the heat gun to shrink the tape. In our first attempts we used a plastic plotter paper tube which melted if heated up to much. This meant we were not able to fully contract the tape which left excess epoxy on the tube. With a metal mandrel, we could heat the tube to the theoretical limit of the epoxy and hopefully remove most if not all of the excess epoxy.

    Part III: Carbon Fiber removal, fin cutting and igniters (11/27/02)

    Peter, Paul and Nick were present at the second work party on SRC III. First off Peter brought 3 lb of dry ice, in an attempt to remove a carbon fiber tube that had stuck to the mandrel. We hoped that by cooling down aluminum motor casing, it would allow us to slip the carbon fiber tube off. It didn't work.

    The tube is stuck on the mandrel for 2 reasons. The first being that the wax paper being used as a release mechanism melted and marred when we heated the tube. It allowed the epoxy to adhere to it rather than being a barrier. Secondly, the heat shrink tape we used compacted the tube very tightly to the tube. Not good for removal purposes. We may yet use liquid nitrogen, and try and cool the tube down even father.

    We filled the tube up with dry ice, and immediately water started to condense and freeze on the outside. We think that aluminum and Carbon Fiber have similar thermal expansion coefficients, so both tubes shrunk at the same rate. We were hoping that one would shrink more than the other. After some futile pounding and pushing and pulling we decided that it was not going to come off. The remaining ice was then disposed of, properly of course. :-)

    A little background on how the tube was made:

    The mandrel was a Aerotech RMS K700 casing. There were 2 wraps of 5.9 oz bi-directional carbon fiber. Approx 3 oz of West Systems epoxy was used. Wax paper was wrapped around the mandrel to serve as a release layer. Heat shrink tape was used to compact the CF and epoxy.

    More on our other Carbon Fiber tubes can be see here.

    Fin Cutting

    Booster fins.

    Sustainer Fins

    The booster fins were cut and sanded by Peter O. They are a standard trapezoidal shape. These were chosen mainly for looks rather than anything else.

    The sustainer fins were cut by Paul C. The are a "upside down Nevada" shape. Again, personal preference only.

    More on making the fins material can be see here.

    Igniters

    Nick made up a few homemade igniters. He used the igniter man igniter kit. The pyrogen had dried out, and no acetone was avilable to reconstitute it, so no pyrogen was added at this time. Only conductive primer and the sealer were used. The wires used were from a old davey fire electric match lead.

    We performed a ground test of just the conductive primer and concluded that pyrogen will be needed to light any composite motor. The directions recommended using the conductive primer to light BP motors and small composite motors.

    A small homemade igniter sized to fit a 24mm reload. Conductive primer only.

    Part IV: Nose Cone Construction (11/29/02)

    Nick worked on creating a lightweight nose cone for SRC III. The nose cone was made with blue insulation foam. This is a fairly dense foam that can be cut and sanded easily. 3 pieces were cut and epoxied together so that the formed a large, rectangular block. Then a small 3/8 dowel was inserted into the center piece. A larger 1/2 piece was glued onto the very end of the 3/8 dowel, so that it would fit better on the lathe. The the whole assembly was mounted on a lathe. We turned it down to the correct diameter, and tried to create a "ogive" shape. The nose cone is 9.5 inches long and 2.1 inches in diameter. The shoulder is only 1 inch long because the nose cone is "non-moving". That is, it won't ever be leaving its place during the flight, so a small shoulder can be used.

    The nose cone turned out great, and is very light. All that is left is to put a thin layer of epoxy and microballons on the surface to protect the nose cone from dropping and dings. Also, the tip may either be filled down, or we may cut it off and put a balsa tip on.

    Notice glue lines from foam.

    Part VI: Egg Protection Trials (12/02/02)

    Jeff worked on creating a protection system for the eggs. High density foam was used to tightly wrap the eggs, and acted as a shock absorber between the eggs and the wall of the rocket tube. Along with this, some cushier foam was placed between the eggs in case they came out of their packaging.

To simulate the worse possible situation that SRC III could encounter in a launch, the tube (representing SRC III's payload bay) was thrown off Nick's 24 foot roof. The egg survived multiple droppings onto the lawn with no parachute to slow the descent. The egg survived several trials in which the tube was thrown onto the lawn. The eggs eventually broke when Nick tossed it upward and the tube crashed onto the concrete. As Jeff put it, "it looks like the eggs are broken." Nick promptly sounded the all clear whistle so that the neighbors could resume normal activity.
    The test was considered successful because, although the eggs broke when they fell onto concrete, SRC III will be landing on grass with a parachute deployed. The system was accepted by the committee, and will be used in SRC III.

    And for us on Earth? Paloski's work may help here, too. Ultimately his research is about making it easier to learn--and that's something we do every day of our lives.

    As usual, NASA is compelled to point out some way that space research will generate a tangible benefit on Earth. It's like a mantra: "Yes, we've spent billions, but look at all the space program spinoffs we use every day on Earth!"

    I wish that there were a way to harness the pure excitement of exploration, without having to make excuses. Of course, as seen elsewhere on Slashdot, you can only spend so many billions of dollars before folks start expecting results.

    Meanwhile, I'm rooting for Armadillo Aerospace and the other backyard hobbyists with deep pockets.

  25. What "enhancements" most threaten accessability? on Ask an Expert About Web Site Accessibility · · Score: 4, Insightful

    The AC poster made a statement that shows a potential problem:

    The Opera Browser is very good for acessabillity [...] Not forgetting the useful mouse gestures.

    I would suggest that the "mouse gestures" are the antithesis of "accessible". They require a level of fine motor control that might not be possible for someone with decreased motor skills. Imagine someone using a pointing device keyed to eye movement -- if Opera's gestures were turned on, a quick look to the side could generate an unwanted "Back" action.

    Mouse Gestures, then, are an "enhancement" that may actually decrease usability for the disabled. What other "enhancements" that are in the works or becoming part of the standard actually derail disabled access to web browsing and other applications?
