That's actually a common misconception. In GPS positioning you have four variables to be determined, your position on the earth (X,Y,Z coordinates) as well as the error of the receiver clock. Because you don't have a high precision atomic clock in your Garmin and the Master Control Station doesn't monitor and adjust the clock in your handheld you need the signal of a fourth satellite to use its high precision clock to calculate exact time differences (distances).
The reason many handheld or car navigation systems also work with three satellites is that they keep one variable, usually the height, fixed in their calculations. You can either use the last known value if a satellite disappears over the horizon or you can just get it from, for example, the navigational maps in your system. When you're driving along some road it generally doesn't matter whether you're 100 meters above or below the road, but it may matter if you're 100 meters to the left or right. This usually doesn't impact the usefulness of the device very much but may allow you to get a fix on your location when you otherwise wouldn't.
The difference being the market. One is a server market, the other is a cult.
You mean a religion. A cult is a religion that just started out and has yet to garner success.
Besides, Apple can claim to be a derivative of Christianity and/or Judaism, giving it instant credibility. One has the Book of Job, and I'm sure the other has the book of Jobs. And every other products is sold as the second coming.
Sup Dawg! I heard you like quotes so we put a quote in your quote so you can quote while you quote!
That's actually not how it worked. You pushed the wheel up or down and depending on how far you moved it it adjusted scroll speed, it actually was a pretty smooth input device, as far as i can remember. However it was limited to just scrolling, and couldn't control all the features of the device like the ipod wheel does. Here's a pic for whoever is interested: http://tinyurl.com/cxqbng
I didn't even know about this feature until now, but it isn't all that useful if you've got 'find as you type' enabled. Anyway, I would really like to use this, so does anybody know of a way to use these keys in firefox without disabling the search functionality completely?
IMHO, any change like this should at least make it possible to mirror the old way of doing things, in case people like it. Reading the comments on Aaron Seigos blog it seems that that's actually possible. A reply of his to a comment similar to yours was
@Dass: "mmh
CRAZY IDEA:"
not crazy at all. that's *exactly* how folderview-as-your-containment works.
neat, huh? =)
The talk this Heise article is about (which was held at 24c3 on friday) is actually available as a full-length download in various formats on mirrors (look for "2273-en-toying with barcodes") and on bittorent along with most of the other talks given at this (totally awesome) event. And it's in english, too.
That may be true, but maybe it is this kind of thinking that lies at the root of the problem. A single car trip (drone flight) doesn't make a difference. If enough people think like this (it seems that currently a lot of people still do) and you've got a pretty big problem at your hands.
In this special case however there may be a point to be made of the reward in understanding justifying the cost in environmental impact.

... you have to stop, come back, and scroll again

...and that web app will have enough fail-safes to run locally for short periods of time. actually I think we're a lot closer to this than you think http://slashdot.org/article.pl?sid=07/03/30/19522ever heard of SAP? http://en.wikipedia.org/wiki/SAP_AG
