  1. monthly hydrogen perpetual motion posting on Big Advance In Hydrogen Production Could Change Alternative Energy Landscape · · Score: 0

    "nothing to see here. move on"
    I wonder what happend to the past 20 or so "free hydrogen" breakthroughs posted in Slashdot through the years.

  2. run slashdot posts through this grader? on Automated System Developed To Grade Student Essays · · Score: 1

    That could be an interesting execise. And its free. I probably would not get a good grade.

  3. analyze form more than content on Automated System Developed To Grade Student Essays · · Score: 1

    "Form"- spelling, grammar, sentence structure, pragraph devlopement, etc.- should be half of an essay's grade. Especially due devolving literacy standards these days of students who spend all therir time on digital devices and testing.
    Only a human can understand if the essay is on topic, clever, humorous, special, etc.
    Computer assisted grading will cut the necessary number of graders in half. This would save a lot of cost for SAT essay grading. Please the human grader could concentrate on the more interesting task of grading content.

  4. not so new: 3rd most common planet finder on Kepler Watches White Dwarf Warp Spacetime · · Score: 1

    After doppler shifts and transists, gravitational lensing is the 3rd most used method to find planets.

  5. bogus until they are actual use on Israeli Firm Makes Kilomile Claims For Electric Car Battery Tech · · Score: 2

    There has been a claim of "revolutionary battery technology" from some US energy lab every month- carbon nanotubes, lithium air, etc. But few have ramped up to daily production road use. And few have gone bankrupt with $100s millions US DOE grants along the way.

    I really, truly hope one of these claims becomes reality one day. I would like a 1000-mile electric car in my garage that costs the same as a petro car.

  6. major in something else than computers on Ask Slashdot: Preparing For the 'App Bubble' To Pop? · · Score: 1

    Like some kind of science. Then you could write software for that specialty.
    These "vertical" markets have different economic cycles than computers.

  7. CERN computers could mint bitcoins in offseason on CERN Gives Away Higgs Boson Particles To 10 Lucky Winners · · Score: 1

    to defray expenses

  8. cost to archive for a century too on What Does It Actually Cost To Publish a Scientific Paper? · · Score: 1

    In the era of paper, storing copies of papers was not a trivial cost. First the journal's publisher and professional society should keep copies. And hopefully copies are distributed among libraries and scientists around the world. Publishers areborn and die. So are scientists. Then their collections are often lost. Libraries usually fare better.

    If you think the web will fare better, look at all the garbage web pages from the 1990s that have been lost. The huge turnover in dot.com businesses and changing electronic standards. And the extreme danger of jurnal publishers hoarding their copies on just a few servers and streaming them to users. I've seen far more unrecoverable disk crashes than libraries burnings/floods/quakes.

  9. just like press release from 1960's on Laser Fusion's Brightest Hope · · Score: 1

    "Unlimited fusion power is only five years away"

  10. can you replace the keyboard with this? on The Leap Motion Controller is Sort of Like a Super Kinect (Video) · · Score: 1

    It seems like you dont have to click keys anymore. You just "air type" and have an app convert it to keys.

    Musical keyboards too.

  11. science of cooking food on Ask Nathan Myhrvold What You Will, Live Q&A April 3 · · Score: 4, Interesting

    One of the TV news magazines showed some of the things you learned about new, scientific ways of cooking food. What was the most amazing thing, in your opinion, that you discovered?

  12. "just around corner" technology for decades on Major Find By Japanese Scientists May Threaten Chinese Rare Earth Hegemony · · Score: 1

    Seafloor mining has been talked about for decades, but hasnt gone anywhere. besides rare earths, there may be large concentrations of more conventional minerals.

  13. immense progress since late 1990s on Study Finds Universe Is 100 Million Years Older Than Previously Thought · · Score: 1

    The age of current universe wasnt even known until a factor of two then., i.e. somewhere between 9 and 22 gigayears. The two dating methods of recession and low metal stars gave widely different answers. The 3rd method from the background radiation spatial wavelengths clinched it.

  14. sounds like a DAPPA RFP from 1970s on DARPA Tackles Machine Learning · · Score: 1

    "Deja vu all over again" for lon-undersolved computer problems.

  15. large debts != google material on How To Bet Money On Your Future Success · · Score: 1

    A smart, creative, would have gotten lots of grants for undergraduate, supplemented it with a good parttime job or entreprenuership, and would have been paid a surplus in grad school. That how I got out of two ivies debt-free.

  16. include HOA, prop tax, insurance, all utilities on How a Programmer Gets By On $16K/Yr: He Moves to Malaysia · · Score: 1

    These are all living costs you must pay each month where you live. Some places fold in a lot of the insurance and ultilities into the HOA fee, while others pay separately.

    And I include recurring information/communication/entertment fees as utilities, e.g. landline, cable, smartphone, internet, newspaper, netflix, gaming subscriptions, etc. For some people this is their second highest monthly costs.

  17. reminds me of Harvard B-school hack on 41 Months In Prison For Man Who Leaked AT&T iPad Email Addresses · · Score: 1

    Applicants could peek ahead at the status of their admissions by adding a few numbers to their URLs on the site. Harvard rejected all of the people who tried the hack. And told other ivy b-schools about them too who also rejected them.

  18. consolidation into google plus? on Ask Slashdot: Which Google Project Didn't Deserve To Die? · · Score: 1

    I was under the impression that much of this "closed down" functionality was going to migrate to the walled garden of Google Plus. The would mirror facebook's methodology and compete with them.

  19. year-long space test opened seats on Sarah Brightman's ISS Trip In Peril · · Score: 1

    Spare Soyez are kept as lifeboats in case space station become uninhabitable. But these lifeboats must be recycled within seven months due to lifetime of fuels and gases aboard. There are apprixomately three astronauts launched every 3 months for a six month rotation in fit these parameters. The plan to keep two of astronauts up for a whole year opened some short-term trip opportunities the private space touring group was hoping to purchase.

  20. Phantom of Opera actress on Sarah Brightman's ISS Trip In Peril · · Score: 1

    Not the first, but longest. Married the author and shared in his billions.

  21. PhD = right-size research projects on How Scientists Know An Idea Is a Good One · · Score: 1

    A PhD is a several year apprenticeship in some area where you learn to do right-size research projects. The largest error of many new graduate students is to choose a project that has already been done, one that is too trivial to get publications out of, or one that is too large to finish in 3 years of work. There are fields outside of my PhD where i think I know pretty much the basic knowledge,e.g. computer science. But I would not be able to choose a "right size" R&D project without help.

  22. learn "mindfullness" on Ask Slashdot: Best Way To Block Noise In a Dorm? · · Score: 3, Interesting

    A technique of eastern cultural temperment akin to "dont sweat the small stuff". It is a kind of meditation.

    If the noise is loud enough to damage hearing, then you need to physically protect your ears.

  23. this has been known for decades on Microbes Likely Abundant Hundreds of Meters Below Sea Floor · · Score: 1

    Life has been everywhere drilled into sediments or rock as long it is below 120C temperature.

  24. immediate plasure of fitness important on Ask Slashdot: How Do You Stay Fit At Work? · · Score: 1

    I agree the jury is still out whether it helps, hurts, or has little effect on longetivity.
    The immediate pleasure of fitness includes feeling better during the day, doing things more easily, fitting in to clothes and seats. A well chosen exercise can be fun and mentally refreshing.

  25. I keep the two separate and focused on Ask Slashdot: How Do You Stay Fit At Work? · · Score: 2

    Other than hall walking breaks to relieve muscle tension, I do vigorous exercise outside of work.

    Its a lot like advice for insurance: combing investing and insurance in one product usually shorts both.
