  1. Re:six axes? on Razer, Valve, and Sixense Working On Motion Control For PC Games · · Score: 1

    They may mean 3 position axes and 3 motion axes, so you get 3 position coordinates and 3 velocities - and hence you get 3D position + rotational movement (pitch, yaw and roll) + 3D translational movement (velocity).

    A 3D accelerometer measures force directly - probably on 3(?) piezo-crystals - and therefore acceleration (F=ma) and can derive velocity via integral calculus 3D position and 3D velocity and hence also pitch, yaw and roll. In theory if you swing your iphone in a big circle over your head it should know when it is exactly back where it started - but I doubt it is millimeter-accurate after swinging around 360 degrees. In the same way that when you wildly move your optical- or wheel- mouse around on the table and bring it back to exactly the same spot the mouse pointer will NOT be in the same position on the screen.

    Microwaves will give you directly absolute position in 3D (by bounce-back echo time - light travels 3m in 10 nanoseconds) and velocity in 3D (by Doppler Effect). So Microwaves will know when you have swung around 360 degrees and are exactly back in the right spot.

    so you can fill in the fields on screen, print out the document, sign it and fax it back to the goverment department or insurance company that you downloaded it from! And so their OCR software can read it without requiring human intervention. That way they don't have to change any internal work processes that they have been using for years - but you the customer downloaded, printed and made it machine readable -saving them work.

    yeah, but you have to press 2 buttons and then lift your two cameras with your 4 sided PMMA/perspex/plexiglass box every time - he has a hinged L-shaped piece of perspex and one button - a more elegant solution - half the button presses, the cameras don't move and less weight.

  11. Re:10% improvement isn't that much on Lotus Teases With a Fuel-Agnostic Two-Stroke Engine · · Score: 1

    and there is nothing environmentally desirable about the mono-culture of rapeseed, which rapes the soil of nutrients, requiring (usually mineral) fertilizers, which ruin the nitrogen content of waterways - and the fertilizers had their own CO2 costs of production - as well as being a non-renewable resource.
    I'm waiting for someone to calculate the real cost of any of these "bio" fuels. Mostly the environmental damage is virtualized away so no-one notices (like seabed death 100's of miles away due of excessive N2 runoff)

  13. Windows doesn't fully support multiple Desktops on Will Tabbed Windows Be the Next Big Thing? · · Score: 1

    Windows really only has the concept of ONE Desktop. If you create 4 desktops (as Systinternal's desktops does), you CANNOT move programs between the desktops.

    This is the CORE reason why Windows never supported virtual desktops, and Mark Russinovich's solution is the simplest.

    Quote from Mark Russinovich Sysinternal's Desktops.
    Sysinternals Desktops uses a Windows desktop object for each desktop. Application windows are bound to a desktop object when they are created, so Windows maintains the connection between windows and desktops and knows which ones to show when you switch a desktop. That making Sysinternals Desktops very lightweight and free from bugs that the other approach is prone to where their view of active windows becomes inconsistent with the visible windows.

    Desktops reliance on Windows desktop objects means that it cannot provide some of the functionality of other virtual desktop utilities, however. For example, Windows doesn't provide a way to move a window from one desktop object to another, and because a separate Explorer process must run on each desktop to provide a taskbar and start menu, most tray applications are only visible on the first desktop. Further, there is no way to delete a desktop object, so Desktops does not provide a way to close a desktop, because that would result in orphaned windows and processes. The recommended way to exit Desktops is therefore to logoff.

  15. Re:Oh really? on In AU, Film Studios Issue Ultimatum To ISPs · · Score: 1

    Your logic and analogy may be sound and all, but the fact is that it is reasonably technically possible for an ISP to know when a user is sharing a file illegally, but it is not reasonably technically possible for your telecom to know if you are plotting a crime on the phone, nor for a car manufacturer to know you will do burnouts, nor for the Post Office to know what illegal dvds you are shipping. And it is this technical possibility that these people are trying to exploit for their own ends. AND these people can imply or claim that the ISPS know all this and are exploiting this revenue-generating high bandwidth usage for their own ends.

  22. Blackberry charging on Universal Phone Charger Approved By UN Body · · Score: 1

    My Blackberry 8700v (yes, it's old) rejects my Tomtom-USB car charger after 5 seconds. So I can't charge my Blackberry in the car.

    My solution to Blackberry on WindowsXP and Windows7, is simply to connect the Blackberry, then the Windows hardware wizard asks if it can connect to Windows Update for a driver - say "yes" and a simple and unobtrusive "RIMUSB.sys" on XP (RimUsb_AMD64.sys on Windows7_64) will get installed automatically. Then you can charge your Blackberry normally without any annoying Blackberry software being installed.

  23. Why not simple Mercury-like orbits on New Kind of Orbit Could Ease Mars Communications · · Score: 1

    Why not put two satellites 120 degrees in front of and behind Mercury?
    -one of them is always visible to both Mars and Earth
    -they are Kepler orbits requiring no thrust
    -the gravitation pull of Mercury at 120 degress is on average 0.0000000556 that of the Sun. =SunMass/MercuryMass/sqrt(2-2cos120)

    Maybe the answer is below
    -to get to Mercury-like orbit requires 4.6 times more energy than to get to Mars-like orbit from the Earth. (MercuryMass/MercuryRadius-EarthMass/EarthRadius)/(MarsMass/MarsRadius-EarthMass/EarthRadius)
    -adds maximum of about 40 seconds to signal path.(simple pythagorus)

    4 things "wrong" with stainless steel slides - though I love em too.
    1. 90 deg F+ sunny summer days and your stainless steel slide is gonna be 120 deg F.
      I know coz I burnt myself lots as a kid.
    2. When it's not 100 deg F you may burn the skin between your thumb and forefinger by gripping the edges and sliding fast - that's probably why these new fibreglass slides have huge grips on the side so you can't get the skin between thumb and forefinger on it, you have to grip with your WHOLE flat hand..
    3. when kids fall- and they will - steel does more damage to the underneath of a chin + tongue+teeth+lips then fiberglass. I know coz I can still feel the pain 30 years later :-)
