  1. First "user interface" with any smarts on John E. Karlin, Who Led the Way To All-Digit Dialing, Dies At 94 · · Score: 5, Interesting

    He was also the Father of the User Interface. He was the first to take human factors into consideration in the design or products.

    No, that goes back at least to the Gilbreths. Frank Gilbreth created time and motion study for industrial work. His wife, Lillian Gilbreth was more on the product side. She is responsible, among other things, for kitchens with long continuous counter space with cooking surfaces and sinks at the same level.

    The first "intelligent user interface" is hard to pinpoint. Railroad interlocking control boards were close. They prevented the operator from doing anything that would cause a collision (that's why they're called interlockings) but didn't help set up routes. The General Railway Signal NX system in 1936 was probably the first automatic intelligent user interface. Routes were set up by pressing a button to indicate where a train was going to enter the controlled area. Lights on a track model board would then light up indicating all the places it could exit. The operator would select one, push one exit button, and all the switches and signals for the route would be set accordingly. The control system took into account all trains present, and all routes already set up, so only safe routes could be set. The operator could even set track or switches out of service and the system would route trains around the area of trouble.

  2. No good info yet on Super Bowl Blackout Caused By Defective Protective Relay · · Score: 1

    Even EL&P's coverage doesn't say anything substantive. When we start seeing articles with diagrams of the feeders, maybe we'll know something.

    An enclosed stadium in Louisiana in winter shouldn't be anywhere near its electrical load peak. No air conditioning load.

  3. Non-English XML on Ask Slashdot: Do Most Programmers Understand the English Language? · · Score: 1

    I've seen XML with tags in Japanese. Tags in large-character set languages are troublesome. When text has to match exactly, full Unicode is a pain. There are homoglyphs; you can't tell by looking if there's a match.

    There are huge headaches associated with Unicode URLs and domains. There are complex rules for avoiding domains that look visually the same but are different to DNS, and trouble getting the registrars to enforce them. Although they're fully supported by browsers today, they're not widely used in Japan or China. Arabic, Hebrew, and Cyrillic domains are widely used; they're unambiguous, provided that you stick to one language set per string.

  4. QNX does this and gets it right. on Moving the Linux Kernel Console To User-Space · · Score: 4, Informative

    QNX, the real-time message passing operating system now owned by Blackberry, does all "console" handling in user space. They've done that for years. That's because, in the embedded world, you can't assume the target machine has a console, or even a serial port.

    When you build a QNX boot image for an embedded system, you can add any programs you want to be available as soon as the system boots. All device drivers are in user space, so that's how the initial set of drivers gets loaded. You can also load applications that way. Having a file system is optional. If necessary, all software can be in a ROM. This allows scaling down to small embedded devices.

    A serial console program is available, and is loaded into most systems that have a serial port. There are other options for systems that don't have a serial port, like connecting it to a network.

    There's also a system logger. It's common to have the system logger log to some network destination elsewhere, so problems out at Pumping Station 42 are reported to the control center far away.

    Linux has tried to emulate this architecture. More drivers are in user space. But in Linux that was an afterthought, and it shows.

    Central Computer will do a "no crapware" install for you if you ask. They actually printed "no crapware" on the invoice for the last machine I bought.

  6. Hiding negative information on Wikipedia on Site Copies Content and Uses the DMCA to Take Down the Original Articles · · Score: 4, Interesting

    "Reputation defense" on Wikipedia has become an issue. Here's a wash cycle on Wikipedia, carried out on behalf of Michael Milken, one of the notorious financial crooks of the 1980s. ("Biggest fraud case in the history of the securities industry." back in 1990.) He has a self-admitted paid editor on Wikipedia editing his article to make him look good.

  7. What's new about this? on How Not To Launch a Gadget · · Score: 1

    What's new about a wrist phone? Swatch had the Swatch Talk wrist phone in 1998. Samsung had one in 2001. If you want one right now, there are several on Amazon. They're cheap, too; well under $100 for an unlocked phone.

    There's even a full Android device in a watch size announced. This thing can supposedly make phone calls, shoot video, browse the web, get your location, etc.

  8. Good for embedded systems on Life After MS-DOS: FreeDOS Keeps On Kicking · · Score: 4, Insightful

    Why not? For embedded systems, when you need more than a boot loader, don't want all the excess baggage of Linux, and don't want to pay for one of the embedded OSs like QNX, it's a good option.

    You also know that FreeDOS doesn't have a "phone home" feature, a HTTP server, a mail server, or something else on an open port running in the background without your knowing about it.

  9. We had a solution on Richard Stallman's Solution To 'Too Big To Fail' · · Score: 1

    We had a solution to "too big to fail" for banks. There was the Glass-Steagall Act, which forced a complete separation between brokerage and banking. Worked fine from the 1930s to 1999. Then it was repealed because the big banks wanted to get bigger. "Today, Congress voted to update the rules that have governed financial services since the Great Depression and replace them with a system for the 21st century. This historic legislation will better enable American companies to compete in the new economy.", said the Treasury secretary in 1999.

    Right there is how we got into this mess.

  10. Takings clause issue on School Board Considers Copyright Ownership of Student and Teacher Works · · Score: 1

    No, not student works. That's a 5th amendment "takings clause" issue. This is a public school, an agency of government. Public school students are not employees. Not even close. Any taking of student property must be compensated.

    I don't think any public school board has been dumb enough to try this before. State universities have been careful about this, after some troubles. (Private universities are a different case. They're not state actors.)

    However, they are unusually clueless. www.funimation.com is nothing like valid HTML. It's an obfuscated Javascript file with a starter bit of Javascript to execute it. But it doesn't work because the character coding is wrong. I'm not sure whether their site has been hacked, or whether their site is a hack.

  12. Take the course on line on Dozens Suspended In Harvard University Cheat Scandal · · Score: 2

    You can take this course on line. for $1,045 to $2000. At Harvard, I would have expected "Introduction to Congress" to be taught by an former member of Congress, but it's just an ordinary instructor.

    I'm watching the first video. At the beginning, the instructor says that all you need to know to start this course is that "Congress" exists. At 00:02:35, he's talking about the proposal to change the rules to prevent filibusters from stalling Congress (only the Senate, actually). The speaker is interesting, but if you don't already know a lot about American politics and the structure of Congress, you'll be totally lost.

  13. Re:The 3D thing is kind of fake on Light Field Photography Is the New Path To 3-D · · Score: 1

    It looks like it loads a full set of pre computed images for all available POV and focal points. Sure there is probably a rough threshold but that's a limitation of bandwidth, not the data.

    No. This is an image taken from one camera position, with one sensor, with tiny lenses of different focal length over adjacent pixels. There is only one point of view, but depth can be inferred from depth of focus.

    This is not a hologram, a time of flight image, or a 3D composite of images taken from multiple locations. It's much simpler than that.

  14. The 3D thing is kind of fake on Light Field Photography Is the New Path To 3-D · · Score: 0

    Lytro has a Flash program which will work on their images. Here's a good example. This shows a girl blowing big bubbles, and you can see the background through the bubbles.

    Lytro is doing more than an image warp, but less than multiple points of view, as you can see in this image. Click and drag on the image, and the point of view changes slightly. Note where the nearby orange toy occludes the car in the background, and see slightly more or less of the car appear. That looks correct. But look at the background through the bubbles. The background behind the bubbles doesn't change when you change the psuedo-POV. So they don't really have a stereoscopic view. Here's one with a row of glasses which shows the same problem.

    This is more like the kind of fake 3D added to movies in postprocessing. They're converting the image to layers and moving the layers relative to each other. To pull this off, the nearer layers have to be shown slightly larger than they really are. One you notice this, it's kind of creepy. It also fails for images with a range of depth but which don't layer well. This plant image shows that. The near part of the plant is being treated as a single layer and warped, which looks wrong.

    It's a useful tool for some special effects, perhaps, but not a breakthrough.

  15. The Bar Has Been Lowered A Lot on As Music Streaming Grows, Royalties Slow To a Trickle · · Score: 1

    Yes, the bar has been lowered. Myspace has somewhere upwards of 5 million bands. Some of which might not suck. There are more "band members" in the US than construction workers.

    The notion of "rock stars" comes from a period when the tooling cost for vinyl records was high. That's so over. It's running on inertia and old fans now. I was just looking at a list of "big concerts" for 2013. Some of them raise the question "are those guys still alive?" Elton John? The Doobie Brothers? Rush? The Who? The Beach Boys? They have to tour; anybody who wants a copy of their content already has it. The highest-paid musician in the US is Dr. Dre, but that's from his line of headphones.

  16. This is a robotics problem on Cooking Up the Connected Kitchen · · Score: 1

    That's the problem.

    It's quite solveable. There are many automated industrial food processing facilities. In Japan, there's a whole range of vending machines which automatically make pizzas, french fries, etc.

    A refrigerator/microwave combination, where items go in standard trays and a suitable mechanism conveys trays into the microwave and out, wouldn't be that hard. Parents could phone in dinner for their kids.

GitHub shall not be liable to you or to any third party for any modification, price change, suspension or discontinuance of the Service.

    A classic example of a formerly open database becoming closed is CDDB, the track list database for audio CDs. Once open source, the current owner, GraceNote, doesn't even allow clients other than their own, and inserts ads. Another example is Google's takeover of the historical netnews database and closing it to full downloads.

    To avoid that, it's important that creators limit the rights that some service gets merely by hosting the content. A service like GitHub could claim that as soon as someone else makes a check-in, the aggregated content becomes theirs. The GPL, which covers derived works, prevents that.

  20. Can they do a mouse? on The Human Brain Project Receives Up To $1.34 Billion · · Score: 1

    So they say they need 1000x the power of the current largest supercomputers to simulate a brain at the neuron level. So they should be able to simulate a mouse brain, which has 1/1000 the mass of a human brain, right now. Can they do that?

    There's a hubris problem in this area. Some years ago, I went to a talk where Rod Brooks was touting Cog as strong AI Real Soon Now. He'd done good artificial insect work. I asked him "Why aren't you going for a robot mouse? That might be within reach." He answered "Because I don't want to go down in history as the person who created the world's greatest robot mouse." The Cog project tanked in 2003. As one grad student said, "It sits there. That's what it does. That's all it does."

    If we can't simulate the lower mammals, which are pretty good at moving around a complex unstructured world and getting through the day, no way can we do humans yet. This brain project sounds like a boondoggle for building a huge supercomputer that they won't be able to program.

    They need to do a mouse first.

  22. Somewhat a dead issue outside Clearwater FL on Book Review: Going Clear: Scientology, Hollywood, and the Prison of Belief · · Score: 3, Interesting

    Does anybody still care about Scientology? They've been shrinking since Hubbard died. They've sort of centralized at Clearwater, FL, but other than that, not much seems to be going on.

    The amusing thing about Scientology is that it doesn't use science. It's locked into Hubbard's writings and 1930s technology. The "E-meter" is a skin resistance measuring device, the least useful of the three classical polygraph channels. By now, Scientology should have had online and mobile systems as part of their "auditing" process. A modern "E-meter" should have heart rate, respiration, and face gesture recognition sensors, with functional MRI in R&D. But no, they're still using skin resistance.

    This may be just as well. With modern sensors, and detailed historical data for each member, much more monitoring and control over the emotional states of members would be possible. Fortunately, Scientology is too inept to bring that off.

  23. Logs indicate no overcharging on Dreamliner: Boeing 787 Aircraft Battery "Not Faulty" · · Score: 4, Interesting

    The battery charging voltages and currents are logged, the logs go to the flight recorder, and they don't indicate overcharging. There are monitoring circuit boards in the battery case, separate from the charger, which report this data. Either the charger failed in some way that caused an overcharge without the voltage sensing detecting this, or the battery itself failed.

    The NTSB says they haven't found anything defective yet. The burned battery is enough of a mess that it's hard to extract much info, but they're using spectroscopy to check that the composition of the components was correct.

    The grounding is necessary. The JAL aircraft at Logan only had 22 takeoff/landing cycles on it, and this has now happened twice, so the odds of further trouble are high. Over the next few days and weeks, batteries and chargers will probably be pulled from other aircraft and cycled through pressure chambers, shake tables, and hot/cold cycles in attempts to induce the failure.

    Meanwhile, I suspect that there are frantic efforts at Boeing to design a replacement that doesn't use lithium-ion batteries.
