I mean, in iOS world, we don’t believe in garbage collectors, and we think the Android guys are nuts. I suspect that the Android guys think the iOS guys are nuts for manual memory management. But you know what the two, cutthroat opposition camps can agree about? The JavaScript folks are really nuts.

There is absolutely zero chance that you can write reasonable mobile code without worrying about what is going on in system memory, in some capacity. None.

essentially on the iPhone 4S, you start getting warned around 40MB and you get killed around 213MB. On the iPad 3, you get warned around 400MB and you get killed around 550MB. Of course, these are just my numbers–if your users are listening to music or running things in the background, you may have considerably less memory than you do in my results, but this is a start. This seems like a lot (213mb should be enough for everyone, right?) but as a practical matter it isn’t. For example, the iPhone 4S snaps photos at 3264×2448 resolution. That’s over 30 megabytes of bitmap data per photo. That’s a warning for having just two photos in memory and you get killed for having 7 photos in RAM. Oh, you were going to write a for loop that iterated over an album? Killed.

http://www.slashgear.com/apple-ipad-why-the-stylus-isnt-dead-0884799/ #stylus #finger #apple #ipad A stylus has come to be seen as an apology for a bad UI, a way of making undersized or tricky on-screen controls accessible when fingertips won’t cut it. Ironically we’ve lost sight of the stylus as a legitimate input method in it’s own right; ironic because while in computing the pen is seen as niche – the domain of artists and the unenlightened – in the real world there are many more people who can write than can type.

Does this sound ridiculous, a perverse #fantasy of some balkanized #Web of the #dystopian #future?  Nope: it’s all true, except that my #laptop is actually an #iPad and my #browser is #iTunes / #iBooks. 


On the Web, the very idea that the right to read a website would vary from country to country seems patently absurd. #Cyberspace is flat, after all, just computers talking to computers. You, the reader, do not need to concern yourself with where these electrons on your screen are coming from, and neither do I, their publisher, need to care where they are going. And when somebody attempts to artificially block those #electrons — say, #China and its #Great-Firewall — it’s the kind of the thing that the #US #Congress and the #World Trade Organization get worked up about
