  1. Re:Roland Piquepaille article on Nanocosmetics Used Since Ancient Egypt · · Score: 1

    He used to link his stories on slashdot directly to his blog, which was an excerpt from the real article. There was a link in his blog that went to the article proper.

    So, nothing too horrible, right? There's a few extra issues:

    1. It pissed people off, because they went looking for the article but had to pass through Roland's blog first.

    2. Further to that, he didn't even offer anything of merit when he summarised the original article. If he'd had some truly insightful commentary there, well , ok. But most of it was basically a cut'n'paste of bits of the article, with a bit of filler like, "so yeah, lots of implications there."

    3. There was also rather a lot of ads on his blog, which likely got bajillions of hits/views from him linking from slashdot. I'm all for a bit of profit, but, that smacks of someone taking advantage of the slashdot crowd. Particularly irksome was the sales pitch to people to buy ad space on his site , which specifically mentioned large amounts of traffic from tech-savvy slashdot-type people.

    But I will say that he's settled down over the last 6 months and has not linked directly to his blog from his slashdot postings. But the crowd here holds a grudge for a long, long time. Ask anyone with a UID under 500,000 about JonKatz.

    A little troll-ish there. You could say the same for any high-rise construction worker that liked their job. For all you and I know, that was his one great ability in his life, and he sucked at more mundane things, like flipping burgers.

    Maybe if he loved what he did less than his kids he'd still be there.
    Or maybe then he'd be a bitter child-abusing alcoholic, having been unable to follow his dreams.

    You make sacrifices for your children and I'm sure Steve made plenty. He had a job that - while risky - he loved and it paid well enough for his kids. While he's not able to be there for them now, his estate alone (and no doubt about it, some serious life insurance - Steve knew the risks) would ensure that his wife and kids are well looked after.

  8. Re:Off button? on Teen Creates Device to Track Speeding · · Score: 1

    Making the assumption that all you can do is disable the GPS antenna, and not actually tamper with the logs or the device physically, don't you think the parent might notice something when the device points out that they didn't have a GPS lock (or even PRN sighting) at any time during their little trip? In other words, your scenario wouldn't work against an even-somewhat well designed device.

    If you seriously think a GPS system is able to sight through a solid carpark covering, then think again. A simple ploy like that - going to a location that loses lock and claiming that you were parked there all the time is quite plausible. Disabling the speed sensor on a recent vehicle takes 20 seconds of fumbling under the car (or a few hours of installing a speedo signal line kill switch) and allows the odo readings to match up nicely.

    I won't comment on MacGyver-like abilities of kids these days, but quite a few of my rev-head friends would have been quite capable of doing it when we were that age. And rev-heads are the ones most likely to be wanting to tool around the place un-monitored, and most likely to be ones targeted by parents wanting to keep track of their hijinks.

    But yes, technical merits aside, the whole trust thing is the issue. If you really can't trust your kids enough to be in charge of a potentially lethal object.... don't lend them the car and hopefully, they'll be older and wiser by the time they can afford their own. Hopefully.

  10. Re:A Better System on Car Owners to be Notified of Blackboxes in Vehicle · · Score: 1

    To be honest, you're probably more likely to find one standard in a European car than in a Asian or American car. Also the engines need to have electronic throttles for the smoooothest speed limiters, so generally it's diesels and fairly-upmarket cars that have them.

    But I can attest that it's very handy to have - dial up the speed limit and then just plonk your foot somewhere on the accelerator and it will stay active until the ignition is turned off. On my car there's a detent a little bit past full throttle that overrides the speed limiter, so if you need to you can "unlatch" it temporarily just by putting your foot all the way down - it won't switch back on until you drop below the set limit again.

    And there's nothing wrong with Peugeots - except for the whole insufferably snooty French thing. But the French do make nice cars - and as for standard features, they blow away anything in a similar price range here in Australia.

    But check your distance to the nearest cell tower first before building that big antenna.

    GSM will not connect a call beyond 35km, due to delays due to speed of light and signal processing.
    There's a correction/delay factor built in, but it's only 6 bits from memory - 0-63. Once you get beyond that, it won't work. I used to drive through a spot which happened to be line-of sight to a tower about 40km away - no signal until exactly 35km, then 3 bars on the phone.

    All the antennas in the world won't help you after that. You could have 40km of low-loss coax directly to the cell-tower , and it still wouldn't work.

  17. Re:QA's failure more likely on Big Dig - One of Engineering's Greatest Mistakes? · · Score: 1

    I would guess that installation methods weren't perfect. Epoxy hangers are mounted in hardened concrete, which means that holes have to be drilled. Have you ever tried drilling a hole in concrete with even the best equipment?

    Why yes, I have. I use a Tamrock Axera 7 drill rig, which can bore 1.5 meters a minute through solid granite. It's nice. And it's got 2 drilling arms, so while one is automatically drilling, the other is getting set up for the next hole or performing other tasks (see below).

    It's not easy and extremely unlikely to get a symmetric hole.

    The holes that I drill are actually quite symmetric. They're also 3 meters deep and straight enough that I can put in and pull out a drill-rod with my hands with no binding. And really, there's not much requirement for a symmetric hole. The rods and epoxy combo are quite over-spec'd. Pull-to-failure tests on a nominal 3 ton retaining rod with epoxy binding is in the order of 15 tons or so normally, generally with the rod breaking somewhere before the actual section where it's bound to the rock by the epoxy.


    Then there is the whole matter of mixing the epoxy correctly and having it set properly. Epoxy does not do well attaching to wet surfaces in humid conditions, and there is definitely room for the mixtures (which require a two-part chemical combination) to be put together in inacurate quantities -- even with mixing systems.


    There are two part epoxy cartridges that contain the correct amount for each hole ready to go. In my case, I insert the cartridge (about the size of a large salami) into the hole, insert the bar to be epoxied in and activate my drill rig rotation using a PLC for the correct sequence (rotate for 20 seconds, delay 20 seconds, rotate 20 seconds, disengage). I remove the coupling from the end of the bar and 8 hours later it can (and does) support 3 tons just fine, and it will continue to do so for quite a few years in crappy, loose, wet, corrosive ground conditions.


    Quality assurance failure. It's a design failure from paper-tiger engineers. Give me a break!
