Finding an open wireless connection in many airports isn't always easy, or possible, without a password (or local phone number which is stupid). The difficulty of getting online is why I asked you for and created an…

I spent a week without IPv4 to understand IPv6 transition mechanisms
The time has come to talk about something uncomfortable to a lot of you. You’ve been using legacy methods for far too long. It’s time to move to IPv6. But, of course, there’s a lot more to IPv6 than ‘just’ switching everything over. A lot of systems in the world still haven’t…

Tell me if you’ve been in this situation: you’re chatting about online anonymity with your wife and the other Knight-Mozilla Fellows over a pizza in Florence. A quiet-spoken stranger who had been sitting across the room walks up to your table and says “are you all here for the Tor hackathon?” You respond “why yes, yes…

It’s an established fact on the internet that we have ran out of IP(v4) addresses , and we are starting to see the pressure on obtaining IPv4 space.
