in reply to Zipcode Proximity script

We had a job like this come through as a proposal a couple months ago. Guy had a salesman in zip code A, B, and C. Had a customer in zip code D,E, and F. Wanted to know which salesmen was closest.

The results would be stored on his server. He was basically expecting a hash of each Zip Code centroid in the US measured to every other zip code centroid. Hate to bust the guy's bubble but it would've taked years to do all the calculations, assuming really fast calculations.

So.... Maybe you could eliminate all the zips that aren't + or - 1 utm zone from the one you're measuring from. That might eliminate quite a few. Maybe speed it up a bit. Neil

[1nickt]: stevieb I don;t doubt that there's a difference. BestBuy has "consumer" models only on display.
[ambrus]: 1nickt: for some reason, these days they call every computer "gaming", even ones that gamers wouldn't buy. I've bought a keyboard that was labelled "gamer", despite that it has hard springs and seems to be way better for typing than for gaming;
[1nickt]: I though the gamers like that because they bash the keys so hard.
[ambrus]: and I've seen motherboards with no fast expansion ports for a video card but built-in hardware RAID advertized as "gaming".
LanX has a shaming laptop
[ambrus]: 1nickt: my impression is that the gamers like the softer springs, because fast reaction time is more important to them then feedback from keypresses to recognize typos.
[1nickt]: Ah, I see. I did read some gamer mag reviews, and yes, they lamented the fact that laptops with no discrete video card are sold as "gaming" hardware.
[1nickt]: But, they do have red keyboard backlighting! And gargoyles on the front, or words like "Maxxx" here and there. They know their demographic!
[1nickt]: True gamers don;t buy Dells, HPs, or Lenovos, I think ;-)
[ambrus]: The keyboard I bought doesn't have backlighting. I specifically had to select for that, because so many keyboards these days have lights. Why would I want lights in the keyboard? I want lights in the room, such as on the ceiling, not in the keyboard.
