  1. Re:Battlestar... on The Physics of Space Battles · · Score: 1

    Perhaps future laser weapons won't be like today's lasers and act more like a projectile but at the speed of light, given the recent progress in making light behave like a liquid or a crystal.

  2. spacebattles animations on The Physics of Space Battles · · Score: 1

    Is there a good site for space battles animations? I used to go to spacebattles.com but they haven't added any content in many years.

  3. Sanitizing comments, trolls, first to market on Ask Slashdot: Software Issue Tracking Transparency - Good Or Bad? · · Score: 4, Interesting

    How can a developer have a frank discussion about the product's limitations when in a public forum? My feeling is you'd end up having to sanitize comments for public consumption or be self-censoring your real, honest opinions.

    What about the trolls who will say "hey this has been filed for X years and still nobody fucking fixes it!?? FAIL!!" Who needs that kind of drama in a bug db.

    Yes, open source organizations keep their bug DB public but it is a necessity for them and a different dynamic. Also worth mentioning that security bugs are private even for open source.

    How can you be first to market when all your new ideas are available to any competitor via the bug DB?

  4. Re:Unreliable sources on Yahoo Shuttering Its Web Directory · · Score: 1

    Google's page rank algorithm goes a long way to mitigate that by tracking how many links refer to a given site, but of course Google needs to be vigilant of abuse.

  5. Search wins over directories on Yahoo Shuttering Its Web Directory · · Score: 0

    Maintaining a web directory is like keeping nicely pruned and organized browser bookmarks: nobody does it anymore. Keyword search is good enough in both cases.

  6. Motion activated on From the Maker of Arduboy: Tetris On a Bracelet · · Score: 1

    I was hoping for something motion-activated: Strap one to each wrist and each elbow and get some good old 80's breakdancing going while you play.

  7. Re:I dunno about LEDs, but CFLs don't last on The Great Lightbulb Conspiracy · · Score: 1

    While I was leaving your lawn, I looked up carbon arc lighting and found this cool project: pencil-powered carbon arc light with an Arduino.

    Obligatory reference. Makes me laugh every time.

  9. Yes, there is a cost on FBI Chief: Apple, Google Phone Encryption Perilous · · Score: 4, Insightful

    Yes, there is a cost to privacy. Some lives may be lost as a result of increased privacy and due process. I think most people are okay with that.

    I appreciate the clarification!

  11. Re: Black holes are real, we observe them all the on Physicist Claims Black Holes Mathematically Don't Exist · · Score: 1

    Why are some black holes "supermassive" and others just regular?

    Supermassive one contain more...mass. What a surprise. Supermassive Black holes are found at the centre of galaxies and contain more mass than a single star ever could. (Sag a* about 4 million suns)

    Right, except that if black holes don't exist (according to this paper) then something the mass of a super-massive black hole shouldn't exist, should it? It should have exploded and shed the extra mass.

    Just a random thought: maybe dark matter fills some sort of void created by the explosion. I am not a scientist. :)

    Why are some black holes "supermassive" and others just regular?

    Could we expect what's left after a supernova to, at some point billions of years later, explode again once it's reached that critical mass?

    Could neutron stars turn back into regular stars?

  13. The worst part on Bioethicist At National Institutes of Health: "Why I Hope To Die At 75" · · Score: 1

    The worst part about super long lifetimes will be the old thinking that comes along with it. When old people die, it makes way for new people and new thinking. Imagine some of the cronies in public office living to 150 years old.

  14. Re:Is there a single field that doesn't? on Science Has a Sexual Assault Problem · · Score: 1

    You are guilty of deflecting criticism that the definitions are too broad by claiming that the parent poster is guilty of deflecting criticism. What if I performed an experiment and grouped the results by temperature: cold, warm, and hot? Wouldn't you question what temperature ranges those cold/warm/hot temperature labels corresponded to?
    Labels are thrown around in the media all the time and are often misleading. If you aren't questioning labels then you're that much easier to deceive.
    There is no deflection here - it is a rational question to ask.

  15. Multiple cuts on Microsoft Lays Off 2,100, Axes Silicon Valley Research · · Score: 1

    I worked at a company that made multiple layoff cuts over several months. It was really demoralizing. I hope for Microsoft and its employees' sake that this is the last layoff, else morale will plummet and people will start leaving of their own free will. They should have done just one larger cut and moved on.

  16. Re:According to a sample size of 1 on Study Finds Link Between Artificial Sweeteners and Glucose Intolerance · · Score: 1

    Were you drinking a lot of sugary drinks before the switch to diet drinks? If so, it could be that the impact was more from what you were no longer doing, not what you started doing.

  17. According to a sample size of 1 on Study Finds Link Between Artificial Sweeteners and Glucose Intolerance · · Score: 3, Interesting

    I had a steady weight for about 2-3 years and started drinking a lot of diet soda and gained 10 pounds. I have cut it out almost entirely (before I saw this study, in fact) and I'll see what happens. I still do like carbonated beverages, so I've switched to an unsweetened, naturally flavoured carbonated drink in a can ("Pure Life" by Nestle. Water, CO2, flavour). I was drinking soda water for awhile but the lack of taste eventually made me lose interest, plus there's salt in it.

  18. Re:I need this in comparable terms. on SanDisk Releases 512GB SD Card · · Score: 1

    I still think in terms of double-sided Commodore 64 5-1/4" floppies. At about 320KB per disk, that'd be 1,388,888 disks.

  19. Re:Empirical Data Trumps Information Theory on Information Theory Places New Limits On Origin of Life · · Score: 1

    Considering our planet only has another billion years before its turned into a crispy planet like Venus (killing all life in the process) due to our sun exhausting its hydrogen supply, it seems even less likely that intelligent life which can spread beyond its planet would have time to evolve.

  20. Fracking takes water out of action on US Rust Belt Manufacturing Rebounds Via Fracking Boom · · Score: 3, Interesting

    This article tries to compare fracking water use to other uses (eg. golf courses) but fails to account for fracking water being taken out of the system - it's not recycled, it's disposed of. With lakes drying up or disappearing in California and other countries fighting over fresh water, how can the fracking industry be so wasteful?

  21. Re: Do it yourself? on Ask Slashdot: Best Service To Digitize VHS Home Movies? · · Score: 1

    Did you run into any out-of-sync issues between video and audio? (eg. someone's lips move noticeably before you hear the audio) In the past I had problems, and that was my main reason for not involving a general purpose computer in the initial encoding process this time around.

  22. Re:Do it yourself? on Ask Slashdot: Best Service To Digitize VHS Home Movies? · · Score: 2

    I've been using a DVD Player/Recorder machine to digitize old home movies from VHS-C (using a converter tape in a VHS player) to DVD. Then I rip the DVD into a VIDEO_TS folder using RipIt for Mac and also have it create a .m4v file. I save both formats for posterity, as well as the physical DVD I burned and (for now) the original tape.

  23. Re:Hell no on Bill Gates Wants To Remake the Way History Is Taught. Should We Let Him? · · Score: 5, Insightful

    My personal point of view is that high school history was full of dates and names and difficult for me to memorize. I did not find it interesting, even though on paper my teacher was a published author and one might assume was doing a fine job teaching. Fast forward to my adult life and I have found many sources of interesting historical accounts and am more interested in history now than I ever was. The interplay of different events on different parts of the world is fascinating.

  25. Re:Predators on Giant Dinosaur Unearthed In Argentina · · Score: 2

    Pack behaviour - that was my thought as well. I have seen video of a pack of lions exacting revenge on an elephant. The elephant got so exhausted with all those lions on it that it fell over and the writing was on the wall after that. What a slow, horrible way to go. An article recently suggested that T-Rexes may have hunted in packs which makes it plausible that an animal like the Dreadnoughtus could actually be taken down.
    Also worth considering what vulnerabilities being that large could pose, such as getting stuck in a ravine or falling victim to some other terrain hazard making it easy for predators to wait for it to weaken before striking.
