Phone number change

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

    Nice method of notify :)

    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 :)

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

    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.

    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).

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

    :D

    BTW, idea is great.
