  1. Prove it on Why Are We Made of Matter? · · Score: 3, Insightful

    That the universe started out with equal amounts of matter and anti-matter is an interesting hypothesis.

    It's a shame that an experiment for wearable technology has been stigmatized by ignorant misconceptions about the technology and people experimenting with it.

    The google cow doesn't give all the same kinds of milk and dairy products available from microsoft. What's wrong with having both?
    Also, google is not necessarily free.

  7. How is this big news? on Your Next Car's Electronics Will Likely Be Connected By Ethernet · · Score: 1

    Ethernet is already in widespread use in vehicles. The Tesla already uses Ethernet for almost everything mentioned in the article including real time connectivity to the internet for turn by turn directions, streaming music, diagnostics and more. It also uses WiFi for things like tire pressure sensors. Tesla is just one example; many luxury vehicles use WiFi for their tire pressure sensors. Yet another standard for automotive cabling and the use of existing protocols is common sense and hardly a major breakthrough.

  8. Re:Consumer acceptance? on Tesla Used A Third of All Electric-Car Batteries Last Year · · Score: 4, Informative

    Our Tesla is almost a year old (about 12k miles) and the only things that have gone into the car is air in one tire (until they fixed it for free), electricity, and windshield washer fluid.

    We did buy the maintenance plan (good for everything except tires for 8 years) and I'm sure it will need something, but so far its been basically nothing.

  9. Re:Can someone explain this theft? on Mt. Gox Shuts Down: Collapse Should Come As No Surprise · · Score: 5, Informative

    You are a car rental agency and your customer comes to get the car they reserved. The customer pays and drives off with the car. They return immediately afterward and says they haven't picked up the car yet. Because of a deficiency in the paperwork, the checkout person doesn't realize that a car has already been provided but sees that its paid for and provides a second car. Turns out the customer has used a false identity and can also reissue VIN numbers and now has two cars for the price of one. You look out in the parking lot the next day and realize all your cars are gone and you only have half the money. Crap. Somebody had the nerve to take advantage of a problem in your paperwork system that has been publicly known for a couple years but you have been too lazy and irresponsible to correct.

    Its pretty obvious that getting the transaction process fixed is the solution. All the exchanges have or are in the process of doing this. Its too late for Mt. Gox. They and their customers are screwed unless they can come up with a way to trace the funds through a byzantine scheme to mix and anonymize and retract the transactions. Building a warp drive star ship would likely be simpler...

    Based upon his productive career and the major breakthroughs he's made in synthesizers and machines that help the blind read regular books, calling him a crackpot is pretty harsh.

    I thinks he underestimates the complexity of the human mind and is overly optimistic about the Moore's law being consistently sustained for several more decades, but eventually we'll probably see much of what he's anticipating.

    The Dutch have 12 medals in speed skating. That's more than a coincidence and clothing cannot account for all that. This is their sport, they have a great crop of young competitors and Sochi is at sea level too.

    If different suits gives our team more confidence - great - this is about the sport and the competitors, not Under Armor and Locheed.

    So now writing code is as simple as stacking bricks? What a horrible and depressing analogy.

  14. Re:Whitelist developers on Is Whitelisting the Answer To the Rise In Data Breaches? · · Score: 1

    No question - its a *huge* job, but unfortunately we have to start. We probably cannot retrofit this into old stuff - it has to be inherently baked in to future execution environments - especially operating systems and web browsers.

    Its gotten so bad with VBA that Word now makes you OK the execution environment when you open the document. Presumably classes of programs like the Perl interpreter would potentially be risky software that requires an OK to run at all. Same thing with shell scripts.

    You would have to give permission, but at least it would be a roadblock to malware and zero day browser vulnerabilities.

    One of the closest things we have for this is Apple's iTunes walled garden. Apples OSX does a lot of this but many people just turn it off...

  15. Whitelist developers on Is Whitelisting the Answer To the Rise In Data Breaches? · · Score: 1

    Why not have a no cost public registration process for anybody who wants to write an trustworthy executable program. Issue a certificate for each individual developer who is added to the list of contributors for a trustworthy program. Make it voluntary. If you want to develop or run anonymous or old software - go right ahead - you've been warned so you can be careful.

    *All* execution environments would need updates to support this so it won't be easy or quick. This is not a new idea, but having it popularized and in widespread use is the challenge. We all haven't really cared enough to take the time to make it happen. Its unfortunately clear that its now necessary.

    As developers we could get valuable feedback from users and would have an additional motivation for quality. It could serve to protect our profession.

    As people who use programs we would at least have a tool to deal with some of the f*&^ed up bull shit we are increasingly having to put up with. This would make viruses and malware a thing of the past. High security systems like heath care, payment and financial processing and civil defense and services would have a potent tool to eliminate a huge piece of the security puzzle.

    Why don't we do this?

    Yes, chemical energy is out for sure. It would require efficient mass to energy conversion which is theoretically possible but have no current safe technology to achieve. That might be a solvable problem though.

    It would be cool if somebody could check the math on this

    A Boeing 737 weighs 49896 kg (wolfram alpha)
    1 unit of earth standard gravitational is 9.807 meters per second
    Accelerating a 737 at 1 g takes 489330.072 newtons
    The Chinese EmDrive produces .36 newtons per kilowatt (http://www.wired.co.uk/news/archive/2013-02/06/emdrive-and-cold-fusion ignore the cold fusion part)
    1 gram of mass converts to 25 million kilowatt hours (wikipedia)
    Accelerating a 737 sized ship at 1 g takes 1359250.2 kilowatt hours using the EmDrive concept
    0.054370008 grams per hour would be consumed

    That's not very much mass.

  20. Re:Space or Lack of Gravity? on The Human Body May Not Be Cut Out For Space · · Score: 1

    For trips to distant location, rotation may not be necessary. If the ship could simply accelerate at 9.8m/s2 halfway there and decelerate at the same rate for the other half, much of the trip could provide normal gravity without rotation. This only works for trips in the solar system though because after close to a year you would be approaching the speed of light. Does anybody see anything wrong with this approach?

  22. Re:As a glass wearer on AMC Theaters Allegedly Calls FBI to Interrogate a Google Glass Wearer · · Score: 1

    You make a good point - and Google does. When you get Glass, Google provides guidelines for use and etiquette including specifically saying not to wear it in a movie theater. The prescription add on is an option from a third party company not affiliated with Google. Glass is an early adopter beta-style product. Its experiences just like this that Google and everyone else needs to build a better version 2. I bet the next version has a lens cap and an led indicating that a photo or video is being recorded.

    Guys like this are what gives glass a bad name. Its about what you would expect a theater to do if you pointed a camera at the screen the whole time. That said, you couldn't really record the whole movie, and even if you could, it would be jittery and not great resolution. Yet another case of misunderstood technology being foolishly abused.

    OK, first of all, her work was not with x rays, it was with radioactive elements. Second the radiation wasn't leaked - they willingly and foolishly exposed themselves to it. She was a physicist and chemist - the biological science to understand the dangers had not yet been done. You have to remember her work was done more than a hundred years ago. Radiation was invisible to them and in their day equivalent to magic. The dangers of radiation were poorly understood even many decades after her death. To put her achievements into perspective, it would be like someone today providing a full verifiable explanation of dark matter and dark energy with working practical applications. She laid the foundations of some of the most terrifying (nuclear weapons) and most majestic (voyager spacecraft powered by nuclear energy) achievements man had accomplished in the 20th century.

    She was well educated, even at an early age by her father. This is the critical difference between modern times and the renaissance. Then, women were rarely offered opportunity and education. Now it is available for anybody who wants to do the work. Its obvious that genius has little to do with gender.

    I'm not suggesting that she was the greatest genius of all time, but to say that there are no great women is an insult to her legacy and half the human race.
