And then there's Boston.

Funny, but also maybe relevant. Boston is one of many cities that resulted from the slow expansion and merger of a group of small towns that were essentially separate communities before the days of modern transportation. It has lots of "centers" that used to be separated by forest and farmland, but are now a continuous urban area.

It's not hard to find other cities that developed this way. Other cities grew from a specific original center, usually a port area, and were never a "merger of equals". I wonder if the study distinguished these two major cases, and has anything to say about what (if any) structural differences we might find between them.

Be careful that the "better caching" you see isn't actually pre-fetching, where the app downloads several of the next few links in the background so that if you click one, it loads much faster. Problem is, that counts against your data even if you never do click those links.

I've done a number of demos of what a site can do to you with pre-fetching. I make a page that shows viewers a few pictures, but also has "hidden" links that you don't see to other images, videos, etc. There are several ways of including such links without the browser actually showing them, which I won't waste time with here. I also include at least one link that's visible as an ordinarily link pointing to a large file that takes a while to download. After talking a while about other parts of the page, I tell the person to click on that link -- and observe that the content shows instantly, although it's obvious large and should take a while to download. This gets across the concept of pre-loading, and why it's useful. But I can also explain that it means stuff you never looked at may have also been downloaded.

Then I tell them to take a look at the source (perhaps teaching them how to do that), and point out the hidden links. I invite them to imagine what the pre-loading could have "installed" in their browser's cached without their knowledge. For instance, they could now be on their local government's terrorist or drug dealer or religious heretic or kiddie-porn lists because of what was just pre-loaded, and the evidence is sitting in their cache. I invite them to discover just what those links actually pre-loaded. And no, I won't tell them how to do that, any more than an actual hostile web site will.

Sometimes I grin and tell them that if they haven't done anything wrong, they have nothing to hide, right? ;-)

Actually, the hidden links generally point to rather innocent stuff, like tourism photos or wikipedia pages or cute cat videos, but they don't know that unless they figure out how to see the hidden content. The most useful is probably a page that simply explains that I could have linked to anything on the Web, and I'll leave it to their imagination what could be in their cache as a result.

The cool devs still do, though, because hardly anyone is making money on the Android markets.

Heh. I have a number of friends (acquaintances, colleagues, etc.) who are giving up on IOS, after numerous cases of their apps rejected by Apple, and then in many cases duplicated a month or two later by an Apple app. This tends to lead to a certain amount of what we might call cynicism about the whole process.

I like to remind them (or tell them, if they haven't read their history) that this has always been the story in "cottage industry". You do the work on your own time, and the employer then decides whether what you did deserves pay (and often keeps the rejects rather than returning them to to the worker). Historically, people working in cottage industries have been rather poor, since the employers control the market and take most of the income for their own coffers. In the modern software industry, the employers also normally claim any "intellectual property" that you develop, which of course includes everything that you create if you're a software developer.

But it's nothing new; it's how "unregulated" industries have always worked. Maybe it'll be fun (in a historian sense) to stick around and see how it all plays out in the long run.

And this is why such services actually exist. For example, in the nearest town (pop. ~30,000) there are two shops that will do repairs on things like iPhones/Android phones (the usual stuff - repairing broken screens, replacing dead batteries, removing the SIM lock from any locked phones, replacing home buttons that have stopped working and the usual other wear-and-tear failures that smartphones suffer over time).

I lived in the US for a few years. We all knew it was the richest country in the world (and much richer than the country I'm from) but I was astonished by how common obvious poverty was. I thought our inner cities were bad, but I'd never seen things like trailer parks and some of the small towns in the south that look like they belong in the third world.

We've had chip&pin here now for over a decade, and people still forget their cards.

However: in nearly every system you can put your card in while the cashier is still ringing up your goods, you don't have to wait for the total to come out. When the total does come out the wait for the transaction to complete after entering the pin is normally well under a second on any remotely modern system.

Everyone knows that the military airplane became obsolete once radar was invented. Same thing here. Must be true....

Cat and mouse, as always. Stealth subs aren't a new idea (go watch Red October, one of my all time favs) and we have only scratched the surface in that area. Even in the 80s when I was in the air force, the Navy was considered the strongest leg of the Triad. That isn't likely to change soon, although the technology they use certainly will.

I was about to say that if you are in an area where it is acceptable to use shotguns (300ft from a home, in the county is the rule in NC) then yes, excellent target practice. I keep the shorter military/police grade buckshot in my combat shotgun, holds around 9 or 10 shells. But in all seriousness, these will be getting shot down, as not everyone cares what the law is, and will just pull out a gun and shoot it down even if they live in the city.
