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.

The Full Story of #Nokia and #Microsoft - How we got here, and why Microsoft will fail with Nokia handsets just like it did with Kin http://communities-dominate.blogs.com/brands/2013/09/the-full-story-of-nokia-and-microsoft-how-we-got-here-and-why-microsoft-will-fail-with-nokia-handset.html

Ok the news is out. I told you literally two years ago, that the Windows Phone strategy would be the death of Nokia’s handset business, and today we have the final nail in that coffin. I honestly, truly with my hand on my heart, hoped this day would never come, and that my prediction would be seen as wrong. But unfortunately I was correct (once again). I do tend to know this industry. And I was the first to tell you, on this blog, that Nokia’s handset business just died. I told you when it happend, and more importantly, I told you why it died. It didn’t die with the crazy Burning Platforms memo, nor with the announcement of Microsoft Windows Phone either. So this is my (first) full epitaph to Nokia. And we have to have a bit of history. (Long blog warning - this runs 12,000 words, so get yourself a cup of coffee, this will take about half an hour
