Reinventing the wheel…

So I’ve been working on the bits and bytes of SSL a lot lately which has required me to look at the OpenSSL code. Long story short, it’s not the prettiest code I’ve ever seen (by a long shot). But it does have a few gems. This gem is going to one of my new interview questions:


void update(unsigned char *buf) {
  int i;
  for (i = 7; i >= 0; i--) {
    ++buf[i];
    if (buf[i] != 0) break;
  }
}

What does this function do? Do you think this is actually faster then obvious the alternative?

mytreo.net hacked or selling email addresses?

So just about every website/company I do business with that requires an email address, I use a unique email address. The email address takes a very simple form: <company name>@synfin.net. The most important rules is that these email address are never used anywhere. So when I noticed I started getting spam to the email address for www.mytreo.net (no I still won’t post it so that spam harvesters can get it, but you can probably guess what it is), it would appear one of two things have happend:

  1. The people behind www.mytreo.net sold my email address to someone and at some point it was given/sold to a spammer
  2. Someone hacked the www.mytreo.net servers and dumped all the email addresses for all the registered users

If someone has a 3rd idea why, I’d love to hear it.
