New site: Blekinge.IT

As much as I try to get rid of domains I don’t use, I can’t avoid registering new domains. I recently registered two domains (singular and plural) for a project with codename Green November.

Another domain I recently registered is Blekinge.IT. At some point in the future I want it to be a site about IT and telecommunications in the Swedish province Blekinge, but for now I only use it to aggregate local news sources.

This was also a test in registering .it domains. I had to print, sign and send a fax (!) to fulfill the registration, but otherwise it was really easy.

fmod() in PHP is the worst !”#¤%&/()= function ever!

I hate floating point artithmetic and I really hate fmod() in PHP. It’s useless.

fmod — Returns the floating point remainder (modulo) of the division of the arguments

If you calculate 36 modulo 7.2?  What do you get? Zero, yes. 7.2*5=36. No remainder!

What if you use fmod in PHP? 

$ php -r 'echo fmod(36,7.2);'
7.2

WTF? Excuse me? Is that the result from IEEE 754 hell, a parallel universe, or what?

Now I’m betting on the function below. I hope it won’t let me down.

function modulo($n,$b) {
return $n-$b*floor($n/$b);
}
