Vint Cerf about IPv4's 32-bit address length

A few weeks ago, I wrote With the Americas running out of IPv4, it's official: The Internet is full for Ars Technica, where I explain where all the IPv4 addresses went.

In the comments, a reader posted a link to an interview with Vint Cerf where Cerf explains how we ended up with the limited 32-bit IPv4 address space. Well worth a listen. The 32-bit thing starts 26 minutes in. Basically, IPv4 is the test version of IP, and IPv6 is the production version!

Nikon FE and/or AI lenses: manual focus in the digital era

Last week, I wrote a review of the Nikon F65 camera. Although the F65 is more than a decade old, it supports most of the photographic automation that we're used to with our digital cameras. The F65 left me wanting to go even further back in time, so this week I'm going to explore manual focus photography with a Nikon FE SLR and Nikon AI and AIS lenses on my current Nikon D7100 digital camera.
