Vim is 20 Years Old Today!

Amazing to read via Ars Technica that Vim is 20 years old today! In the proverbial “vi vs emacs” religious war, I’ve always come down firmly on the side of vi/vim…. but mainly because I started using vi 25+ years ago back in the mid-1980s when vi represented a quantum leap forward from “ed” and “ex”! 🙂

I climbed the steep learning curve for vi/vim many years ago, wrote my .vimrc macros and continue to use it extensively even today. Of course, today on my Mac and Linux systems I’m using vim vs. actual “vi”.

The Ars Technica article has a great history of Vim and is well worth a read for those who use vim as their editor-of-choice. (And even for those who don’t…)


Want to Learn About Deploying IPv6, DNSSEC? Attend the ION Conference in Toronto on Nov 14th

Would you like to learn about how to deploy IPv6? Would you like to hear from people who are already using IPv6 within their networks? Would you like to learn a bit about DNSSEC and how it can help you secure your online presence?

If so, please join us in Toronto, Ontario, Canada, for our next "Internet ON" (ION) Conference on Monday, November 14, 2011, starting at 12:30pm and sponsored by the Internet Society (my new employer). The sessions on the agenda include:

  • New ISOC Initiative – Bridging the Divide Between IETF Standards and Industry-wide Deployment
  • Panel Discussion: Challenges and Opportunities in Deploying IPv6, DNSSEC, and Other Key Technologies
  • World IPv6 Day Recap (my presentation)
  • Ask the Expert: Next Steps to Implementing IPv6
  • Closing Remarks and Q&A

We're looking forward to providing a great session for people to ask questions and talk about how to get these technologies actually deployed in networks today.

The ION conference is part of the larger 2011 Canadian ISP Summit that takes place on the following two days and is included as part of the registration for the Canadian ISP Summit.

However, registration for the ION conference is FREE if you just want to attend the half-day session on Monday. You can sign up through the Canadian ISP Summit registration page, where one of the available options is for the ION ONLY registration.

(NOTE: If you do sign up for the free ION Only registration, the lunch and dinner listed on the agenda are not included. Those are part of the full registration.)

If you do want to register for the full Canadian ISP Summit, which has a great agenda of technical and business talks , we have a discount code of "ISOCDC" which can get your $50 off the registration if used by November 11, 2011.

We just had a very successful ION event in Buenos Aires last month and we're looking forward to great conversations and discussions up in Toronto - I hope to see you there!

P.S. A couple of people have already asked me if I'm going to be able to spend more time in Toronto (and meet them). Unfortunately due to family medical issues I'm just in Toronto for Monday and will be flying back Tuesday morning. Normally I would have loved to stay for this full event because some of the other sessions look great - and Toronto is also an outstanding place to visit.

Oops! Google’s GMail iPhone/iPad/iOS App Pulled From AppStore

Well, Google's iPhone/iPad/iOS app was there for a little bit in Apple's AppStore... but now it's been pulled down because of "a bug that broke notifications". I did download the app a few hours ago to my iPhone and iPad and saw the errors mentioned in the blog post on both the iPhone:

Gmail iphone error

and the iPad:

Gmail ipad error

It's too bad, because in my initial usage, the app seems to work very well. Here's a shot of my inbox that looks like, well, pretty much any other email inbox:

Gmail ipad inbox

As Google's blog post indicates, the app has some cool features and use of gestures. I'll be using it for the next few days to see how it works.

Meanwhile, Google's team is obviously going off to make the notifications work!

44% of SIP Implementations at SIPit 29 Supported IPv6!

Last week (Oct 24-27) was the 29th SIPit interoperability test event hosted by ETSI in Monaco. Organizer Robert Sparks has provided his usual outstanding summary of what occurred:

The key point for me, given my new role, was right up at the top:

44% of the implementations present supported IPv6.

Now, of course ideally we'd like that to be 100%, but hey, it's at least a good start!

There is also some narrative further down the report about "IPv6 Focused Tests" with some interesting info. One interesting note seems to be this:

Most UAs that supported dual-stack had a configuration to tell the application to ignore any returned AAAAs due to issues encountered in deployments where endpoints autoconfigured IPV6 that didn't actually work.

In the web world this has been referred to as the "happy eyeballs" problem where a browser will try a DNS AAAA record to get to a site over IPv6 and then eventually will fail back to trying the A record to go over IPv4. The delay will cause the user to be very UNhappy. There are a couple of ways to address the issue with the usual one being to try both IPv6 and IPv4 addresses simultaneously and then connect over whichever one responds back first. (There is an entire "happy eyeballs" Internet-Draft that goes into this topic for those interested.)

From this simple sentence it would sound to me like the implementations are NOT supporting a "happy eyeballs" approach for SIP but are rather providing an "ignore IPv6" configuration setting. I wasn't there so I don't know... but I would hope that over time all dual-stack SIP implementations would move to supporting this kind of approach (versus disabling IPv6).

It was also good to see that tests occurred in a mixed environment:

We successfully tested calls going though a mix of v4 and v6 hops (accruing Via and Route/Record-Route headers with addresses in both families.

Wearing my security hat I was also pleased to see this:

80% of the endpoints present supported SRTP using sdes

Again, you'd love 100%, but at least this shows the availability of SRTP should companies decide to enable SRTP.

Lots of other great commentary in the SIPit 29 summary around STUN/TURN/ICE and many other issues. Definitely worth a read if you are interested in SIP.

And... if you a creator of SIP-related hardware and software, watch the SIPit website for news of the next SIPit event so that you, too, can join in the testing!

And if you have not heard of SIPit before, here's a video I did back in September 2009 with organizer Robert Sparks:
