Phone number change

My phone number changed. If you have the old one, substract 25898392 from it and you will get my new one!

  1. For those who don’t have your old number, this method of notification gives a chance of 1 in 8960 of making a successful prank call (if leading zeros are acceptable). If leading zeros are not acceptable the chances are even better. You should be using modular arithmetic instead :)

  2. If I was getting 8960 calls a day I would not worry that one of them might be a prank call ;-)

  3. So the new one starts with 06 and ends with 1, right? I’m trying to add an error detection scheme to your new notification method.

  4. Alban: no, the new one ends with 3. If the one you had already ended with 3, you already had the new one (which I have since a few days before FOSDEM).

  5. A binary geek would prefer a “binary mask” instead of substraction. Perhaps can you give a SHA1 of the result ?


    BTW, idea is great.
