In some ways that’s a little surprising because, back in 2010, Jobs famously criticized large phones. He didn’t think anybody would ever want to carry a big phone, going as far as saying that “no one’s going to buy” one. The market has since proved him wrong and, if we’re to believeBloomberg’s reporting, clearly Jobs had changed his mind before his death in October last year.

With so many reports floating around about Apple’s shift to a four-inch screen, it’s beginning to seem inevitable. If you’re a small-screen fan, now might be a good time to brace yourself. [Bloomberg via The Verge]

I’ve got to say I find this interesting to read now, even after the hype of the last couple of days, where everyone says they are expecting a new 4″ screen. The reason I am still a bit skeptical is that Jobs himself said that a phone screen should be the size that you could hold in one hand and use your thumb to navigate the whole screen. Maybe they (Apple) will say Jobs had agreed to this to help make us feel that it is therefore OK that the screen is being enlarged, but we shall see soon enough.

Googler Daniel Russell knows how to find the answers to questions you can’t get to with a simple Google query. In his weekly Search Research column, Russell issues a search challenge, then follows up later in the week with his solution—using whatever search technology and methodology fits the bill. This week’s challenge: Where on earth?

 

The short answer: This photo was taken in March, 2004. (I know, since I took the picture.) It was shot at the Matei airport on Taveuni, Fiji. The runway there is 910m long (2,986 feet).

How to solve this challenge: In this case, all you know is that it’s somewhere with palm trees (given that it’s me taking the picture, probably somewhere in the tropics), and that the plane has a tail registration number.

If you do a simple quoted search [ "DQ-TRI" ] you’ll quickly find that this is a plane that was in the service of Air Fiji: Info about the plane. It’s a Pilatus Britten-Norman Trislander registered to Air Fiji. (Why use the quotes? Because without them you end up with far too many off-topics hits. DQ and TRI both have multiple meanings. But together in a phrase… they can only mean one thing.)

You’ll find that all planes have tail numbers that identify who they’re registered to—who owns them, etc.. If you read a bit more, about the plane, you can discover all kinds of amazing information out on the open web—who made it, who bought it, where it was sold (and re-sold). For the history of this particular plane, see TheFreeLibrary.com

To get the rest of the story, you can check the Wikipedia page for Air Fiji tells the story. The company started in 1967, but foundered in 2009, selling off all 5 planes in its fleet.

But for our purposes, the first photo on the Wikipedia page is a photo of a plane in a nearly identical location (by Herman Luyken).

The interesting bit here is that the plane in the photo I took is in almost exactly the same spot as the Wikipedia photo. This lets us verify that it’s really the same South Pacific airport (and not some other random airport in the tropics).

If you look on the Wikipedia page, for the Matei airport on Taveuni, Fiji, you’ll find it’s at 16°41′26″S 179°52′37″W, and the runway is 910m or 2,986ft.

Now, how to determine the date?

The folks who looked for a picture by me from a possible trip to Fiji did the right thing. It was a good idea, and it’s the first thing I would have done. Except I didn’t put anything out onto the web about that trip.

And the people who looked for the metadata associated with the image (also called the EXIF data-see the Wikipedia article on EXIF) also had a good idea. Except I stripped out the EXIF data, just because I knew you’d be looking. You have to be a little careful about the EXIF since it can be altered on purpose (or just by accident when the image is edited).

So how to get a decent date range? You also know that Air Fiji when out of business in 2009 and the plane was purchased in 2002, so it has to be between those dates.

But if you compare the pictures side-by-side:

 

 

…you can see that the background foliage is very, very, VERY similar. All of the trees are the same height, even the grass is pretty much the same between the two pictures.

Then, if you do an image search for [ Matei Taveuni airport ] you can find other images from other dates (I could find ones from 2008 and 2004 easily) that let me see what kind of background foliage change had happened during that time. If you look closely, you can see not only that some of the plants had changed, but also the fence posts around the runway as well.

So while this isn’t an exact measure, you can be pretty confident that this picture was taken sometime in 2004. (And I’ll tell you, it was taken on March 17th, 2 weeks after the Wikipedia picture was shot!)

In a more normal case, the EXIF data probably would have given you precisely the date.

SEARCH LESSONS:

1. Once again, using whatever small amount of text you have in an image can often lead you to the kind of repositories you need… in this case, all of the accumulated information about plane registrations.
2. Sometimes you have to look for the forest AND the trees, and by comparing information you get from multiple sources (e.g., pictures from 2008 or information about when Air Fiji bought that particular plane), you can get a pretty good boundary on the possible dates.
