    outsource your work and call yourself the VP of marketing and operations.

    This is better advice than the poster may have intended. With your current size you really don't want to add FTE's just for two clients. Use that good old "people network" and see who you can shanghai on board temporarily (with an eye towards possibly making them FTE down the road). Otherwise you're investing heavily on what is essentially a gamble at this point.

    Er, what's the context for that "5"? If your company only gets 100 emails a day that 5 is actually pretty lousy. (Now if they get 100K a day then it's great!)

    Something like this, (along with whole extra "servo" tracks and a few other tricks), has already been in use for many years but there are limits to how much engineering it's worth going through before it's easier/cheaper to just find a better material.

    its a plastic fresnel lens
    That is one type, there are also "bug-eye" lenses and no lens at all, just a plastic honey-comb between the filter and the sensor.

    It is differences between these two elements which triggers...
    Right, and the difference between those elements is generated by the IR coming from the zones which is what actually matters for purposes of aiming, hence my use of the word "zones" instead of confusing the issue for the poor sod who's trying to solve his problem. See more on this below, (the sensors don't matter).

    The are all like this due to them being two element devices
    There are also quad element, supposedly "more accurate". FYI - the direction of sensitivity is determined by the shape of the lens not the location/qty of the sensors. In the fresnel type you can even see this in the groove pattern. (If the sensor layout were the only factor then a 2-sensor unit wouldn't work at all when rotated 90deg! :)

    Most good systems will give you a diagram
    Er, yes, but we've already determined it is not a good system and the entire point of the question was to solicit assistance. One can, (perhaps erroneously it's true), assume that the poster would have looked at something like that already if it were available.

    Forgot to mention, the reason film isn't used is the coefficient of expansion. There's no temperature regulation in drives (yet) and there isn't a film material in existence that doesn't expand and contract with the temperature. That's actually one of the reasons glass was introduced awhile back, data densities were getting so high that even the rigid metal platters were moving enough to become a factor.

    Cringley must be old enough to remember Bernoulli disks. (They used a plastic film but same concept applies.)

    If you want real enlightenment, learn Smalltalk or Lisp.

    That's the last step.
          Without the foundation of Assembly and at least a couple of other "ordinary" languages, (like Java or C#), it's hard to fully grasp the significance of something like Smalltalk or Lisp.

    THANK you for "getting it", that whole compiler bug thread should be modded off-topic. :)

  12. Sensor orientation on Decent Motion Sensing Lights? · · Score: 5, Informative

    Most of the sensors have a plastic "light guide" in front of them that breaks the sensed area into zones. It is the changing difference between the zones that triggers the sensor. Try taking one of them apart and you'll see either variations in the lens plastic, or even a set of physical baffles between the outer filter and the sensor itself.
          (You can actually walk by most IR sensors without setting them off if you move VERY slowly, which is why better quality alarm systems use radar or specific thermal level monitoring rather than just a change).
          Which brings us to aiming. Most of the time the zones are arranged to be more sensitive to side-to-side motion than up/down. So if you have one oriented 90deg out of "true" then it'll be rather insensitive except in a narrow band. (This is a good way to limit the area of coverage of a sensor without having to break out the masking tape).
          Speaking of which, the height and angle of the sensor makes a big difference for the same reason.
          So I would recommend taking one apart, figuring out the zone layout and adjusting accordingly. (Heck, you can even just set one on a table and see what area it "sees" and how sensitive it is to motion in that area, then turn it 90deg and try again).

    Learn assembly language and write a simple app like rudimentary text editor or line-art drawing tool, something that requires most of the basic IO functions. (Then try an application launching menu - yay memory management! :)
