Issue #26 - 2012-01-23 - Why does your site not link to perl.org?!

latest | archive

Hi,

I am currently in Austria skiing with my family. I thought we won't have Internet access here but it turns out the 'Zimmer' (B&B) where we stay every year has installed wifi. Which in itself is funny. This house stands on the hill-side, and the only building within 200m is the where the cows live. Yet the wifi needs password and the password looks like this:

oGPmC0PEkTKwWa80sqWRtTnjfY

Yes really. I have no idea how someone comes up with the idea of creating such a password nor is it clear what are they afraid of? That the cows will hook up to the net and illegally use it?

Anyway, now that I can use the Internet I can also prepare the Perl Weekly and send it out.

Enjoy....
