  1. Re:remember, there's no free lunch on Theoretical Shoe Inserts Could Power Your Gadgets · · Score: 1

    I think there would be a direct trade-off with efficiency and the springiness of the shoe. You are right that it would have to return to prepare for the next step, but I imagine that would be most efficiently achieved by your foot somehow "pulling" it back to neutral, maybe through the lifting of the heel relative to the toes?

  2. Re:remember, there's no free lunch on Theoretical Shoe Inserts Could Power Your Gadgets · · Score: 1

    Good point, I would probably prefer the cushion to help me bounce back up for my next step, not sap the energy from my step and trickle charge my phone. I'd be willing to try it out, though.

  3. Re:NFC works with cheap RFID + has security elemen on Sound-Based System Promises Chipless Phone Payment · · Score: 1

    How much do you think it costs to embed microphones and audio processing electronics? Not to mention the resources needed to support this including external power, and potential problems in noisy environments.

    I'd guess the microphone + audio processing electronics will come to less than $1, and they will only be necessary where payments are being accepted - I think a better question is how much the NFC chips will cost in every phone. Noisy environments are likely going to still work because the data transmitted can be relatively little (a few K in a few seconds is probably enough). You have a good point about product tags / etc. but I'm not convinced that we need more than the barcode.

  4. Re:propaganda in your pocket! on Cellphones Get Government Chips For Disaster Alert · · Score: 4, Informative

    wow, scary, thanks for the history lesson, I knew Hitler was big into TV, etc., but I didn't know about this. The link didn't work for me, though: http://en.wikipedia.org/wiki/Volksempfanger
    I'm glad I'm not the only one that doesn't think this is "good for the people"

  5. Re:The Cloud Is Dead on Amazon EC2 Crash Caused Data Loss · · Score: 2

    I think people miss the point of the cloud - saying the cloud is worthless because it "brings people that would otherwise have nothing against you trying to take down your server" is like saying that the internet is worthless because it opens up security risks.
    I for one am glad to be connected, and obviously so are many others. Don't use services that aren't good for you - there are some cloud based services that are great, and some that aren't. It's pretty clear that in the future, things will be more connected, not less - adapt and take advantage of the good parts, the rest will fade anyway.

  6. sneaker net on 3G on The Tablet Debate: 3G Or Wi-Fi? · · Score: 1

    what are the barriers to making a non-cellular-company 3G network - what if I could just make a 3G base station from my DSL line - maybe I could pay for usage on other members 3G stations that would be offset by the bandwidth I provided to others through my own network... just thinking...

  7. Re:Compared to other RG machines... on Purdue Claims World Record Goldberg Machine · · Score: 1

    The really captivating RG machines use everyday objects and simple geometrical shapes to achieve complex interactions.

    not to mention clever uses of potential energy like pails falling down that are attached to a pulley bringing something back up so that it can fall down again. This seemed like a sequence of motors being driven by a battery...

  8. Re:Slashdot comment system on Tim Berners-Lee: Stop Foaming At the Mouth, Twitter · · Score: 3, Interesting

    And it's clearly not keeping users within their existing friend groups, since the number of posters vastly outnumbers the number of friends. :) In all seriousness, I find the comments on slashdot to be at least as informational as the news sources themselves, even if it is only one or two posts out of hundreds, I'm often able to find them, since they are appropriately modded up.

  9. Re:It's poverty, not scarcity on Can Open Source Hardware Feed the World? · · Score: 1
    It seems to me that the project goals address poverty related issues even more directly than scarcity. They are not promoting higher yields through more "industrial agriculture", they are promoting affordable tools that enable decentralized production with local resources. from the first myth of your first link:

    MYTH 1: Industrial agriculture and free trade will feed the world. TRUTH: World hunger is not created by lack of food but by poverty and landlessness which deny people access to food. Industrial agriculture—i.e., large-scale, corporate-run, export-oriented monoculture farming—and free trade agreements actually increase hunger by raising the cost of farming, forcing millions of farmers off the land, and by growing primarily high-profit export and luxury crops rather than food for local people to eat....

    the "large-scale, corporate-run, export-oriented monoculture farming" is exactly what might possibly be avoided if individuals have access to the means of production.

  10. Re:He added accompaniment on Chess Games Translated To Music · · Score: 1

    I think you're missing my point. I'm simply saying that I don't think it's fair to claim that these songs are the chess games mapped onto piano - the part that is the chess game is the random sounding string of notes that was then accompanied to make it sound nice like a composition, which it is.

  11. He added accompaniment on Chess Games Translated To Music · · Score: 1

    I like the idea and everything, but it seems disingenuous to "set blues chords in the left hand to justify the constant tonal shifts from B to b flat in this chess game. The chords modulate from C Major to F Major and finally end in B Flat Major." Not really impressive IMO if the algorithmic compositions can't stand on their own.

  12. Re:Pointlessly small amount of storage. on How Chrysler's Battery-Less Hybrid Minivan Works · · Score: 1

    How much does it compare to a single start and stop? If every start is assisted by the accumulator, the energy savings will accumulate over many starts.

  13. Re:Can someone explain to me... on Facebook's Revenues Leaked · · Score: 1

    You're not the customer. You're the product.

    Agreed - Facebook will fail once people start realizing that they are not 'getting something for free' but instead are providing content for other people to use to make money.
    Unfortunately, Facebook has reached the point where (at least where I live) it is socially unacceptable to not have an account. I look forward to the days of many competitive 'niche' social networking sites, with decent privacy and user control, so that having a facebook account becomes the equivalent of having an aol account today.

  14. Re:Am I the only one... on Google Algorithm Discriminates Against Bad Reviews · · Score: 5, Funny

    have you tried Bing? ;)

  15. Known Evil? on Comcast Warns Customers Suspected of Bot Infection · · Score: 1

    “When we see instructions are being sent from that known evil [Internet address] to one of our customer addresses, we know the instructions from that address cannot be good and that there’s something not good happening on your network,” Douglas said.
    Can someone explain how much they know, are they saying they are aware of the ip addresses of the entire bot? If not, then this seems to me like ISP imposed antivirus software.
    My parents have a Windows machine that nobody touches simply because it takes at my about 10 min. to boot since you have to sit through the anti-virus updates.
    I'm not a fan of viruses / bot-nets by any means, but I hate anti-virus software almost as much. I'm not a fan of the ISP running one for me, or pushing third party software either.

  16. Re:The movie itself is open source on Creative Commons Video Challenges Hollywood's Best · · Score: 1

    They're going to be distributing not just the movie, but everything you need to re-create the movie (or a derivative work).

    Where are the source assets?

  17. Re:90% shared code? on Microsoft Demos Three Platforms Running the Same Game · · Score: 2, Insightful

    I agree, There is nothing special about running with or without a game controller. It sounds like the only thing "new" here is Windows Phone 7 Series. So they got the game to compile for the phone? Whoohoo! Good for them, I never imagined it to be possible.

  18. Re:Straight lines on Chimps Have a Built-In GPS · · Score: 1

    mod parent up. Why make these weird assumptions and call it a discovery?

  19. Still sounds like a boss on Toward the Open Company · · Score: 1

    All income in the company (minus operating expenses), will be passed through the trust metric and distributed to participants -- emphasis mine. Who's determining his own salary?

  20. Re:here we go on NASA and Google To Back New "Singularity University" · · Score: 3, Interesting
  21. Re:One vortex per disk on "Magnetic Tornadoes" Could Offer New Data Storage Tech · · Score: 1

    This wasn't clear to me either, why do they refer to the area holding a bit as a disk? Are they basically saying that you can store 2 bits for every bit by looking at something other than the direction of a magnetic moment? Even that doesn't sound so amazing - seems like it'd be easier to make your magnetic bits smaller, or use something else entirely.

  22. LCD is less efficient than CRT??? on New Energy Efficiency Rules For TVs Sold In California · · Score: 1

    Where do they get these numbers? from TFA: "LCD -- liquid crystal display -- sets use 43% more electricity, on average, than conventional tube TVs; larger models use proportionately more." Is that true?

  23. Oh, great on Scientists Create Easier Way To Embed Objects Into Video · · Score: 1

    unobtrusive corporate logos (emphasis mine)

  24. Re:Where do I apply? on Air Force To Re-Open Pursuit of Cyber Command · · Score: 1

    I think they got you - hook line and sinker... They are looking to recruit. I'd be happier if I hadn't read your post about this being a "fun" job. Why not do something good for humanity? We do not need more cloak and dagger nonsense. Write code for everyone to use.

  25. Re:2 photons, not one? on Hyper-Entangled Photons — 'Superdense' Coding Gets Denser · · Score: 1

    That sounds good, but it still requires that someone send the first 'entangled' photon to the other, so there are two photons being transmitted. I can see it being a powerful 'secure' channel, but not really more dense.
