Interesting presentation by Marc Heuse at Hack in the Box 2012: bugs in IPv6 implementations, differences between IPv4 and IPv6 filtering by large websites, discovering IPv6 systems without brute force address scanning. Did you know that on 63% of networks the ::1 address replies to pings on at least one subnet? And then the hacker security researcher knows which subnets are live.

Last month I posted a picture of the lightning cable I got for € 6.29 at my local super market—a third of what Apple charges.
At first, it seemed to work well except for this warning that pops up when I connect it to my iPhone 5:
Then Apple released an iOS update and after that, I thought the cable didn't work anymore: when I connected the iPhone to the computer using the cable, nothing would happen. Fortunately, it wasn't quite that bad: retrying a few times, especially when switching USB ports, will eventually make the charging and syncing work. Although sometimes the charging just stops after some time.
So it looked like I had a just-barely-functional cable on my hands. But then I used it with a non-Apple USB charger every day for a week, without any issues at all. So it looks like using a third-party lightning cable with a third-party USB charger works a lot better than using the cable with a computer. Just so you know.

RFC 7059, "A Comparison of IPv6-over-IPv4 Tunnel Mechanisms", was just published. This is a document outlining the various way to tunnel IPv6 packets over (under?) the IPv4 internet. I am one of the three co-authors, together with Sander Steffann and Rick van Rein. We were commissioned to write this document by SURFnet.

My review of iWork '13 for Ars Technica. I tried to be open to the new incarnations of Pages, Numbers and Keynote, but that quickly went out the window as I kept discovering new problems. But I still got called out for being too generous by a commenter.
