  1. Re:Little or no wind? on SpaceX Grasshopper Launch Filmed From Drone Helicopter · · Score: 2

    If you look at the video more closely as the grasshopper hovers you can see it leans just enough into wind. There is no such thing as "no wind" at 300m, ever, nowhere in the world.

  2. "Why?" on Why Are Japanese Men Refusing To Leave Their Rooms? · · Score: 1

    There are many things you can ask this question about. Why do you smoke? Why do you use drugs? Why do you cheat your wife? Why do you drink? Why do you lie? etc ad infinum. Most often the simplest answer can be borrowed from mountaineers: "Because we can!" Same with holing up in your parents house. At some point it becomes parental responsibility to throw the cub off the cliff(out the front door), alas this is not the way of the Japanese. In mostly any other society the hikkikomory would soon stop being one as he gets kicked out of the house.

  3. Technical issues on Scientists Work To Produce 'Star Trek' Deflector Shields · · Score: 1

    Sure you can make a very strong magnetic field with superconducting coils, and it takes nearly no power to maintain. However... there are reasons why you cant take electronics or coins in your pockets to the MRI room... I can see that be a significant constraint to a space project. You can work with a weaker magnetic field, but i seriously doubt that it will be of any use for radiation protection, the H field needs to be huge for there to be enough distance to deflect high energy particles. Only way i see it even theoretically working is to first shield the living and working space of craft with surrounding layer of semiconductor - blocks the magnetic field completely and then to put your magnets around the craft. This will create huge problems with heat managment - and everything else.

  4. Re:Mass SMS? on AT&T Rolls Out iPhone Wireless Emergency Alerts · · Score: 1

    How much data do you really need to tranfer? its just a short piece of string. And i think there is also a possibility for SMS broadcast. SMS was put into GSM protocols for just this purpose, using it for texting was not the initial goal, just how it turned out.

    SMS works in the network overhead anyway, it can not overload the network.

  6. Mass SMS? on AT&T Rolls Out iPhone Wireless Emergency Alerts · · Score: 4, Interesting

    Why cant emergency services just use plain old SMS service? "don't go outside, there is a hurricane if you havent noticed"

  7. Many kinds of competence on Ask Slashdot: How Do You Prove an IT Manager Is Incompetent? · · Score: 1

    He might be incompetent in managing, but you better be damn sure you are more competent than him in office politics before you start anything. Are there senior employees who share your viewpoint and are willing to say so? Make sure the manager is not a drinking buddy with higher ranking managers. If you are just a newcomer and he has worked at the post for years, keep your nose out of it alltogether. Office politics are whole different game, and better for you if you never get involved in it.

    One collegue of mine consistently put MY name on HIS works. So obviously when something went south i got the feedback. Rather annoying

  9. Re:Oh the irony on Ask Slashdot: How Best To Disconnect Remote Network Access? · · Score: 1

    General assumption is that safety must work irrelevant of how fubar software goes. Safety is hardware enforced, E-Stop connects to power contactors directly, no software in between. Safety is also safe from disconnections. Loss of conductivity and machine goes to E-Stop mode.

  11. open for interpretation on EU Countries Closer To Mandatory Minimum Sentence Cap For Hacking · · Score: 2

    If only term "hacking" wouldn't be so easy to interpret however you want to. Oh you mistyped your username and our system crashed - haxor! Oh, you discovered a vulnerability in our system, even though you didnt take advantage of it - haxor! Oh your grandmom axidentally connected to neighbours open wifi - haxor! To the prison with the lot of you!

  12. Get a kit on Ask Slashdot: How To Begin Simple Robotics As a Hobby? · · Score: 2

    A kit is what you want, building hardware is not as simple as it seems if you have no experience. Once you have the hardware its mostly software dev. During that phase you learn how and why hardware works as it does. And then when you have played around with a kit long enough, maybe you will want to make your own terminator. By then you might have a clue how to go about it.

  13. Re:Here's my crazy ridiculous idea for the day... on NASA Wants To Test 3-D Printing Aboard ISS · · Score: 1

    As gravity is a non issue at iss, you could make a little hexapod robot(s) with a printing head that just crawls over the object its printing and adds material where needed. Sort of like a wasp building its nest.That way you lose all size limitations, given enough material and time you could even build stuff outside like new modules and whatnot. Lots of material engineering problems to solve obviously, but these are the kinds of things what you can do if you forget about the gravity problem

  14. Re:I don't miss fire ants on Electronics-Loving 'Crazy Ants' Invading Southern US · · Score: 1

    Ants have been around for hundred million years, its a good bet they will be around for as long more at least.

  15. Re:Bad ant strategy? on Electronics-Loving 'Crazy Ants' Invading Southern US · · Score: 2

    Au contraire! Where there are electrecuted ants there must be electricity, where there is electricity there must be humans, where there are humans there must be food all over the place. Some ants getting electrecuted is no drama for a hive as a whole, its like clipping nails for you and me. The dying ants wouldnt affect the gene pool even if they survived.

  16. Re:He's right on Bloomberg To HS Grads: Be a Plumber · · Score: 1

    Atleast here in Estonia trade schools give high school equivalent education + trade, so after trade school you can easily go to univercity(I did). And the little thing about univercities - they are absolutely free. Exceptions being private unis(not worth your time, let alone money) and when you fail a subject and need to retake it you need to pay a modest sum(about 100€ per subject). You have 1.5years to complete a subject you have started, and if you cant manage it in this time you need to pay the fee to retake it. BA is considered a basic degree, but its also considered completely useless, its not really possible to learn a speciality in 3 years. Its a stepping stone to MA, little more

  17. Re:EM "attack" vectors on 9th Grade Science Experiment: Garden Cress Won't Germinate Near Routers · · Score: 1

    I suggest you take a look at something called radar equation(there are one-way only formulas available). Should give you a pretty good idea how much power you can deliver on a molecule by pointing a radio(like a home router) in its general direction. Even resonant effects will make no difference, power densities are negilable.

  18. Re:EM "attack" vectors on 9th Grade Science Experiment: Garden Cress Won't Germinate Near Routers · · Score: 1

    I imagine a fairly minute number of farmers actually subject their fields to sustained 2.4GHz radiation at the intensities you'd get right next to a wireless AP

    Yeah, most impose the fields to way larger intensities, like having an cellhone tower on your field. (thats on slightly different frequencies, but that makes little difference, as power outputs are way higher)

    Dystopian future indeed where bar stops taking my money after i get too drunk to handle a drink ordering app on my phone. That would effectively cut my drinking out night in half.

  21. Re:We could save more people with 24/7 surveillanc on Injured Man Is First Person Saved By a Police Drone In Canada · · Score: 2

    Read a licence plate, if so then barely and only because there are only so many alphanumeric characters and you know how each one fogs out. That besides the point, sattelite imaging is often overestimated, the fact that you can take a look at any place in the world does not mean you can see the whole world with one look. Think of it like that, make a pinhole in a piece of paper and put the paper over a map, now try to read "dragons be here" through the pinhole. Same problem with finding interesting things with satellites, if you dont know where to point the sattelite in the first place you cant find anything.

  22. Re:Not out of the woods yet on Transfusions Reverse Aging Effects On Hearts In Mice · · Score: 1

    Only one way to find out. Now that would be one interesting human experiment, easy too. Old blood sure as hell wont make you old but young blood might make you younger(sort of). Blood transfusions are banned in sports as doping for a reason. It would be really interesting to know results of circular transfusions between very young and very old subjects. You could probably make use of some coma patients that are destined to pulling the plug anyway.

  23. Re:Mars is decieving on Mars One Has 78,000 Applicants · · Score: 1

    Biocontaminating celectial bodies is against international treaties, so no, no plans to terraform Mars. However Mars may already be biocontaminated, probably is, all the probes that went Mars probably took some life along and some may have survived. You dont want to know how many bacteria are actually around(and inside) us all the time, even clean room environment is not totally free of bacteria. And some bacteria can survive incredibly harsh environments, vacuum is not a problem. Luckily Mars is rather desolate place and surviving and thriving are very different things. Some bacteria has probably made it to Mars, but its unlikely that it starts infesting the entire planet. You really wont know until red planet starts turning murky green

  25. Re:Website with TOS? on E-Sports League Stuffed Bitcoin Mining Code Inside Client Software · · Score: 1

    Something must be horribly wrong if website can access your video card. And if it cant the whole affair becomes totally pointless, i think javascript implementation of bitcoin miner on webpage was made once, it worked but hashrate was so slow it would be entirely pointless to run. And that was a while ago when network hasrate and mining difficulty was much lower. Today when even gpu mining is going obselete fast and being replaced with asic mining it makes absolutely no sense. Unless you just want to slow users computer down. Migth make some sense for litecoin mining as that is more constrained by memory than computational speed
