  1. Re:A linear induction motor is not a railgun. on Navy Uses Railgun To Launch Fighter Jet · · Score: 0

    There are only two significant figures in 240, and only one in 300. Please do not do metric conversions with more significant figures than your inputs.

    On the contrary, please don't drop significant figures during intermediary calculations. But do round the final answer to 6.5.

  2. Recommended reading on Mathematics As the Most Misunderstood Subject · · Score: 1

    Recommended and relevant reading is "A Mathematician’s Apology" by G. H. Hardy.

  3. Re:Does it still exist? on Record-Breaking Galaxy Found In Deep Hubble Image · · Score: 1

    Actually, the way we see it is the way it is "now", from our point of view. Remember that time is relative.

    What this means is that there is no concept of "now" at the location of that galaxy that corresponds to our "now", apart from the point we are actually seeing.

    There is no objective observer that can observe both points "at the same time", and in fact no such correspondance exists.

    To answer your question: yes it does still exist, at least from our point of view of time.

  5. Re:We? on EU Surveillance Studies Disclosed By Pirate Party · · Score: 5, Insightful

    Please don't monopolize the use of the word "we" to mean "EVERYONE". "We" could mean "me and my friend". It referers to a group of two or more people of which I am a member.

    11 500 is two numbers

    Well, if space is a thousands separator it's not.
    And eleven thousand five hundred is four words. Still means only one number.

  7. Re:Perhaps? on Geoengineering To Cool the Earth Becoming Thinkable · · Score: 2, Informative

    Don't design my car to get optimal MPG at 55...target 65, because that is highway speed.

    Due to the laws of physics, the only way to make a car have optimal MPG at 65 is to reduce the efficiency at lower speeds.

    You ALWAYS need more energy to keep the car running at 65, because of the air drag. The power usage due to air drag is proportional to the CUBE of the speed, so it increases very fast.

  8. fishy on Compromising Wired Keyboards · · Score: 1

    The video looks fishy, how does the computer program know when to stop collecting keyboard input? The video shows someone going to the other keyboard and when coming back the program has quit.

    And what about the electromagnetic interference of the whole computer running close to the antenna, and the keyboard of that computer?

    Fishy

  9. Re:Fuel economy on Fuel Efficiency and Slow Driving? · · Score: 1

    Indeed, but I find it very unlikely that you will not be able to pass the car going slowly on that multi-day trip :)

  10. Re:Fuel economy on Fuel Efficiency and Slow Driving? · · Score: 1

    The problem is not the car going slightly slower, the problem is that the cars behind it gets too close to it. Which means that they are constantly accelerating and decelerating to avoid running into it. If you just keep a sane distance and the same speed as the car in front of you, not only will you use less gas, you don't have to be 100% focused every time its speed varies slightly.

    And speed limits are there for a reason, to reduce speed. If you drive 30 when the speed limit is 40, you are within the speed limit.

    I agree that you should not drive excessively slow, but 30 on a 40 stretch is not excessive. 15 may be.

  11. Re:Fuel economy on Fuel Efficiency and Slow Driving? · · Score: 1

    Do you know how much time you lose by going 30 mph instead of 40 mph for 2 miles? The trip takes 4 minutes instead of 3 minutes.

    It probably took you longer than 1 minute to write that post.

  13. Re:Oh, god, no. on "Pull" Barcode Scanning Could Be Android's Killer App · · Score: 1

    Only in Europe. In the US the barcode doesn't carry price information.

    I doubt they do in Europe either, because that would be stupid.

    Normally, they don't. However when I buy stuff att the manual deli they print out barcodes that do have the price in them. Also when I recycle bottles I get barcodes printed out, but they have negative price :)

  14. Re:Interview question - universal answer!! on Testing IT Professionals On Job Interviews? · · Score: 5, Insightful

    It doesn't matter if it's compiler-dependent or not. The correct answer to that question is: "This code is badly written. It never makes sense to write i = i++. You probably mean i++."

    Why are you leaving bluetooth open? Close it to only allow connections with trusted devices, like your headset and your computer. Common sense.

  17. Re:Dont confuse OpenSource with Open Standards on Adobe To Release Full PDF Specification to ISO · · Score: 1

    Only one standard? The Standard? I see no problem in having a few formats to choose from as long as they are all open. A bit of diversity is good.

    Moreover, merging PDF and Open Document seems far fetched, they are completely different things.

  18. ad-hoc or access point on "Free Wi-Fi" Scam In the Wild · · Score: 2, Informative

    Wireless network cards can be set up as access points to. So just looking for if it's an ad-hoc network does not protect you. Turn off all sharing when connecting through public access points and use encryption.

    There you go - free wi-fi!

  19. Re:Testing on Something in Your Food is Moving · · Score: 1

    Actually, when making yoghurt, the milk is first pasteurized, and then new lactobacteria are added. It's not pasteurized again and so yoghurt will contain living lactobacteria.

    There is yoghurt that is pasteurized again, but this is only too prolong its shelf life.

    The first pasteurization is made to kill disease-causing bacteria.
