    The Macbeth Problem 

    You might have noticed that the pictures were a bit too dark lately, right? I just about gave up trying to adjust my home and work double monitors for reasonable color, contrast and gamma. So I decided to part with some monetary units and requisition myself a fine color calibrating apparatus. Just like Intuos2 tablets that used to be prohibitively expensive but are more reasonably priced these days, calibrating devices can be had for under $200.

    For instance, Colorvision Spyder sells for $129.99 at the site powered by the mighty Obidos.

    But then I hear that a slightly more expensive GretagMacbeth Eye-One is much better. But the company that houses Rufus the Dog does not even sell those Eye-One thingies.

    What’s a poor programmer to do? I am not sure it’s very practical to spend over 200 bucks on a device that I might use three-four times…

    I bet it would take a long time to explain my problem to the owner of Macbeth Artificial Daylighting Company of New York in 1915

    Normal People Don’t Think About This Stuff 

    If you pay attention to NYC infrastructure like I do, you might have noticed little lights that sit on street lamp poles on certain intersections.

    For a long time I tried to guess their purpose. I thought that they had somemething to do with street lamps. Maybe indicating when light bulbs need changing. But they do not appear on all street lamps. And sometimes they would be attached to a telephone or a power pole. Sometimes they would be lit up, and sometimes not. They do not appear on all intersections. A mystery, right?

    I’ve searched the net finding nothing. Finally I found a reasonable explanation in Time Out New York magazine. The little lights simply appear on the intersections where a fire alarm telegraph box used to be located.

    I knew about fire alarm telegraph boxes from an awesome book Underneath New York. You see, those fire and police alarm pull boxes that were retired a few years back in fact were automatic telegraph boxes. They all shared the same circuit which would be normally closed. When somebody pulled the handle, a clockwork mechanism would rotate a little wheel with a pattern of bumps. The bumps would break the circuit and transmit an id of the pull box in Morse code to a nearby fire station. I guess they did not handle collisions — if two boxes were activated at the same type there would be trouble.

    I wonder how much electricity is wasted on those things.

    Some links:
    Interesting, ADT stands for American District Telegraph. I didn’t know.
    Some pretty cool pictures of fire telegraph control rooms.

    WML: Ligh My life 

    You know what I hate? Well, many things. But I especially hate bad lighting. Office lighting. Even in the best furnished, expensive offices with Aeron chairs in cubes and espresso machine in the kitchen, lighting is provided by the same crappy cheap fluorescent fixtures of horror.

    You know them. There is probably one hanging above your cube right now. Grating on your eyes, throwing glare onto your monitor. Giving you headaches and depressing the hell out of you. Well, of course, it’s not like that everywhere. For instance, a long time ago, in a galaxy called the dot com, I interviewed at a company called Betelgeuse. It was named after an extremely bright red supergiant in the Orion Nebula, which name English speakers pronounce “beatlejuuuze” OR “beatlejuice”, and Russians pronounce “betelgeyze”. It’s a dying star, about to explode (or go supernova if you want to put a positive spin on it).

    In any case, this company had the coolest lighting scheme. They turned off all the lights except a few small spotlights, and lit the corridors with decorative candles. The offices were lit with individual lamps.

    But what can a cube monkey like me (and probably you) do about the lighting situation? Well, for one, you can kill the horrible hell beacon above your cube. Since there is no light switch, here is what you need to do.

    Get onto a chair and get close to the lighting fixture. Your task is to unplug the fluorescent tube from it’s socket. It can be usually accomplished by rocking the tube slightly left-right and away from the socket. Make sure to let your friendly maintenance person and your boss know you are doing this. You don’t want someone trying to open the fixture and get hit on a head with a fluorescent tube. Also, don’t burn or electrocute yourself. This trick only works with fluorescent tubes.

    But Michael, you ask, what else can I do? You can light everything with full spectrum natural lights. A cheapo solution is to use GE reveal bulbs. They cost about as much as regular incandescent bulbs but have a spectrum that is less yellow. Everything looks a bit better. I use Reveal bulbs at home.

    There is also a more expensive option – full spectrum fluorescent fixtures. Remember, in previous WML I mentioned aquarium limps? Well, besides aquarium lights they make full spectrum tubes for regular lighting.
