Some of my favorite podcasts

▼ Anyone who's been reading my stuff on Ars Technica will know that I love podcasts. I'm always adding new ones to my rotation and retiring ones that have run their course for one reason or another. So I thought I'd share some of my current favorites with you.

Two fairly new podcasts that I like a lot are Just The Tip and Clockwise. Just The Tip (RSS, iTunes): "Internet rapscallions Amy Jane Gruber and Paul Kafasis try to make you laugh, in thirty minutes or less." It defies description, but somehow it works. Bonus: unlike most other weekly podcasts, it usually drops early in the week.

Clockwise (RSS, iTunes) comes from TechHive, the home of Macworld and PCWorld. Don't let the gimmicky format used in the first episode deter you, it quickly fades into the background, but it does allow them to get through a whole bunch of topics with a relatively large group of participants in about thirty minutes. A breath of fresh air compared to uninspired episodes of the Accidental Tech Podcast (RSS, iTunes) or The Talk Show (RSS, iTunes)—although I keep listening to those just in case there's an inspired episode, in which case their excessive length is a boon.

The Nature Podcast (RSS, iTunes) and Freakonomics Radio (RSS, iTunes) are a bit overproduced (I really hate that "coming up..." stuff! Come on people, I'm already listening), but not to be missed.

Philosophy Bites is not for everyone, but if you're interested in philosophy, there's a lot of good (bite-sized) stuff there. Be sure to check out the website, because the RSS feed doesn't have the back episodes.

For some strange reason I don't listen to any Dutch language podcasts except public radio programs. If anyone has any tips for Dutch (or English!) podcasts, send me an email or Twitter me.

When do we turn off IPv4?

▼ Over on gogo6.com (through the .vantronix newsletter) Bruce Sinclair asks and attempts to answer the question When do we Turn Off the Lights on IPv4? They actually did a poll on gogoNET. The answers form a beautiful bell curve with roughly the following answers:

< 3 years:	15%
3-5 years:	18%
5-10 years:	28%
10-15 years:	19%
> 15 years:	17%

I've often heard "we're going to be running IPv4 for a looong time..." I don't think we will. The 5-10 years options sounds about right to me. Currently, you can't really turn off IPv4, because you lose access to most of the internet. Sure, we can reach Google, Youtube, Yahoo, Facebook, Bing, Wikipedia and now also Apple as well as thousands of other sites over IPv6, but not Twitter, Ars Technica, de Volkskrant, Microsoft and millions more.

World IPv6 Day and World IPv6 Launch helped a lot to get a good number of top 100 web sites as well as a small percentage of the less popular ones on IPv6. Before and since, it's been slow going. But as it gets harder and harder to get good IPv4, at some point people will start to decide that they can get by—some of the time, at least—with just IPv6. This will trigger additional IPv6 adoption on the content side, and then additional IPv6-only use on the consumer side, and finally we'll have a virtuous circle.

The current assumption that everyone who is "on" the internet has IPv4 will then no longer hold. But not everyone will have IPv6, either. Obviously this will be problematic, and IPv4-only users will add IPv6 just as dual stack (IPv4+IPv6) users will drop IPv4.

Obviously IPv4 will not really go away anytime soon; legacy technologies are hard to kill. But once 80 or 90 or 95 % of all internet users are on IPv6, why keep spending money running IPv4? Once we're at this stage, IPv4 will start disappearing from many places very quickly, similar to what happened to SNA, IPX, AppleTalk and the like around the late 1990s. Except that it's going to be faster because by that time, almost all applications will already use APIs that support IPv6, so it's just an infrastructure change, not a software change.

But maybe we shouldn't throw away good old IPv4 too quickly. More on that later.

Oh, did I mention I posted this article from a computer that's not running IPv4 currently? I turn off IPv4 on my Mac once or twice a year to see what does and doesn't work with just IPv6 connectivity. It's getting better all the time.
