How to get a Time Capsule to actually work in IPv6 without wireless

I have an unusual home configuration, in that I have a routed network.  If you don’t know what this means, stop reading now as you are wasting your time.  While the Apple Time Capsule advertises IPv6 capability, getting it working is rather difficult.  To start with, if you do not use the wireless capability of the device, the controls are really non-obvious.  For another, the Time Capsule appears to ignore the default route capability in routing advertisements.  Hence a manual configuration is required:

Time Capsule Configuration

Looking to the left, one must select “Router” from the IPv6 mode and not “Host” as one might logically expect.  Then, because RAs are not being handled properly, one must manually enter the default route (the long way).

Finally, because you are supposed to be routing, you need to enter some address for the “LAN” side.  My prefix is 2001:8a8:1006::/48.  Note I’ve dedicated a bogus network ::8/64  to the effort.  All of this allows me to do what should have happened automatically; not your typical Apple Plug-N-Play style, is it?  For a company that claims to be IPv6 Ready, I’d say Apple still has a ways to go.  Sadly, they’re better than most.

iPhone: Good or Bad for the Industry?

Take the OfCourseImRight Poll

Is the iPhone good for the industry?

Before Apple released the iPhone it irked me that the pace of technology for cell phones lagged at an incredibly slow pace, the user interfaces were crap, and the deal between cell phone providers and service providers seemed to completely leave the consumer out of the value chain.

Apple changed all of that by going “over the top”, picking a winner in each market, but limiting what deal those winners would get.  That was great, and really stuck it to SPs (who got rich anyway).  They’re trying to do the same thing with the iPad, but in the meantime Apple has changed the accepted development model for businesses.

It used to be that you needed rich web connectivity, and that was good enough.  Now you have to have an Apple app in order to reach all of those customers who love their iPhones.  Good examples of this include Facebook, Airlines, and even that dinosaur who is responsible for Formula 1 promotion, Bernie Ecclestone.  Yes, even F1 has an app.

Here’s the problem: many of the Apps are nothing more than shells for garbage that companies want to shovel at you, and they don’t want others using their data”.  A perfect example is American Express, who requires an app in order to view flight reservations.  THERE ALREADY ARE MANY SUCH APPS. One of them is your calendar program.  One thing you might want to do is download reservation information into your calendar.  But American Express‘ travel web site GetThere.Com won’t let you do it.  You have to download their app.

And GetThere is getting sneakier, as they no longer send many corporate travelers a full reservation in email, but instead simply send a pointer to their web page.  Why are they doing this?  Because they don’t want others like TripIt to capitalize on “their” (really your) information.

And so there seems to be no incentive for these bad players to be good players in an iPhone world, in spite of the fact that there are perfectly capable standards and programs and libraries to deal with much of stuff that’s being exchanged.  What can be done to change that?

iPhone Rollout Redux?

iPhone

Well, July 11th, iPhone Day, came and went.  The Believers waited and most got their phones, but even I could not have predicted the farsical mess that then ensued.  Apple was unable to handle the registration of some 1 million phones in the period of a weekend, while their provisioning infrastructure ground to a halt.  This is the added kick in the pants Believers must really enjoy.

While we wait for news to leak out of Apple as to what actually happened, let me speculate just a bit.  Let us assume the following statements are true:

  1. Apple did in fact test their provisioning capability prior to rollout.
  2. That of the three days the million phones were sold, most were sold and activated in the first twenty-four hours.  In particular, let’s assume a 70%/20%/10% distribution.  I don’t actually know the real one, but we have reason to believe that the load was top heavy on Friday, as problems dissipated later in the weekend.
  3. There were a average of two transactions per registration.  That is- one to provision the phone with services, one to create MobileMe or whatever additional functionality that Apple offers.  Normally we’d include a third for creation of an iTunes account, but since we’re talking about Believers they already have their account.

700,000 sales times 2 transactions over 24 hours would be about 16 transactions per second.  That’s really not that many transactions, considering that benchmarking systems measure that number in the hundreds and thousands.  This makes one wonder: what if we introduced latency into a transaction.  Latency can occur for many reasons, but the biggest one would be some sort of wide area communication.  For instance, an 80 millisecond round trip time would mean that one might not be able to process any more than about 12.5 transactions per second.  Now add a second round trip and you cut the transaction rate in half.

As to Apple’s testing, if they tested their provisioning system either on a local area network or on a network that had lower latency than the time needed to complete the day’s transactions, they wouldn’t have caught the problem.  This is actually a classic concern that most database vendors fully understand, and it is often the reason to use stored procedures.

Anyway, that’s my guess.

iPhone Day: Observe the Tortured Believers

iPhoneWell, today is the day the iPhone goes on sale.  The 2nd generation sleek phone from Apple looks to be quite a bit nicer than the first, starting with improved Internet performance, and considerably better 3G battery lifetime than on any other telephone yet produced, and an open application interface for more applications.  Combined with a great user interface, a friendliness toward the enterprise, and a nice feature set, it will probably make a really good PDA.

If you want to be the first on your block with one of these gadgets, you’re going to have to get up early and wait in a long line.  Otherwise, stores will run out.  In some cases, stores have been allocated less than 20 phones.  Why is that?  It’s not that this device is a surprise, or anything.  And surely Apple could manufacture enough so that people needn’t have to bother with all of that hassle.

But for those few who buy hook line and sinker into the Steve Jobs Reality Distortion Field, it’s a ritual, and they love it.  Surely Steve Jobs wouldn’t want to deprive his followers of that “Joy”.  The Believers get to brag to the rest of us for a few days or weeks about their new gadget, and how everyone is going to copy them.  They are the trend setters for the day.  Of course they spent that day waiting in line.  They’ll spend the next few days figuring out all of the little bugs that Apple has assuredly left lying around.  And then they’ll realize, “Oh dear.  GPS doesn’t work in my home,” as if they didn’t know where home was.  And they’ll read their mail at the restaurant, and even off of their new toys right next to their old Apple monitors that are connected to a recent Apple of some variety.

What’s more, this phone isn’t really cheaper than the previous version.  According to the Wall Street Journal, AT&T in particular has jacked up rates in order to recoup their costs (and, they hope, more).

Still the iPhone is an important innovation, if for no other reason that they have brought to the cellphone market a refreshing jolt of competition that seemed absent.  Sure, LG was interesting, but aside from a few geeks, the rest of us bought Sony Ericsson and Nokia phones, both of which have had the same capabilities for what seem like eons.

So it’s iPhone Day.  Perhaps celebrate by watching your Believer friends suffer.  Don’t worry, Google Believers: you’re next.
