What really intrigues me is that average users feel the same way; it's not just us. Read the iPhone app reviews (current average: 2.0 stars). Ouch! Facebook should hire back Joe Hewitt. His native app was fast and powerful, at the very leas

Having used it in several apps, the iOS SDK is an absolute mess. Part of this is the absurd complexity of it: there are sign-on flows for going to the Facebook app if installed, or to Safari, or to an in-app web view.

I believe iWorks is developed in Pittsburgh (or something like that). Some of the token-recognition code (e.g. detecting calendar events in free text) was developed in France. So I'm not sure it's entirely true that this is the first non-Cu

Hardware acceleration is a huge boost, but the main remaining problem with Android is stutter. This is where run loops really help. As you say, I/O in the main thread and GC are central causes. Both are problems that Apple doesn't have, b

The author briefly touches on iOS' true advantage: the "run loop". In addition, when scrolling, iOS's main thread goes into a "tracking" mode where it filters out certain types of events that might result in redrawing or other performance

Joe Hewitt's original native app was great. But now that Facebook is moving to using HTML all over the place, it's slow as can be.

Yes. The other problem: you're siphoning off the most affluent customers, which are also the most valuable.

This is great! The Apple doc browsers are SO awful. I've filed a report with Apple about it. The problem seems to be that their search/index code always runs locally and is abysmally slow. Can you auto-select the top result by default? It's

About the UPC reselling... he really lucked out. Sounds like that was allowed only due to a contract oversight, and has been prohibited since 2002: http://www.barcode-us.com/upc/upcResellers.html

I think the 4S-specific hardware is the improved proximity detector. This allows you to raise the phone to your ear and speak to Siri instantly. I suspect the older phones' proximity sensor isn't fast enough to support that feature, so Appl

Isaacs is spot-on, and this is one reason why I love Objective-C. NSException is for programming errors, which should be rare. You can use try/catch, but you almost never do. NSError is for expected application-level errors.

Sure, the measure you're looking for is GDP per capita: http://www.google.com/publicdata/explore?ds=d5bncppjof8f9_&#... Inflation is a separate phenomenon that occurs through time and can be influenced by the money supply. The government

This statement is enormously naive. Bill's money has to come from somewhere so the "everything else remained the same" is just not possible... Only if you see money as a fixed quantity of dollars. We're really talking about purchasing pow

Hmm. I'd dispute that. We now have cellular phones, computers and the Internet, cars that are far safer and more efficient, 43" plasma TVs with 500 channels, iPads... You might say "well, those are all gadgets." Fine, but if you cut all of

Who’s in that top 0.1 percent? Are they heroic entrepreneurs creating jobs? No, for the most part, they’re corporate executives. Recent research shows that around 60 percent of the top 0.1 percent either are executives in nonfinancial comp

I have to agree with the article author. Sure, dates and times are really hard to get right. But to say "you know, times are really a kind of data" is a cop-out. Relevant: http://www.joelonsoftware.com/articles/fog0000000018.html

I think the issue is that Apple has devoted plenty of resources to tweaking gestures so that two-finger swipes can be used for both scrolling and navigation. It's a hard problem to solve, but if it's done just right it works. Safari does it

A clever solution used by e.g. Shopkick is to play a very high-pitched sound of a certain frequency on the store sound system and pick that up with the device microphone. I don't know if Apple is using this here. I bet they're instead ident

Someone did. I remember seeing it on Macrumors at the time. They only overheard snippets, after which one of the two said "Let's take this someplace more private".

I also wonder if that's Apple the first time (IPO) or the second time (when the stock surged so much).

A true REST purist would say that you shouldn't put versioning in the URL. Use different Content-Types for different versions of the API, and use Accept headers to indicate the version the client is using.

Good, but why not make all permissions truly optional? I think app authors would be a lot more responsive if they saw stack traces from failed attempts to use a declined permission, rather than the silent number of users who never sign up b

"Hangs out with really bad people"? Please. You make it sound like Anwar al-Awlaki had a beer with al Qaeda so we decided to whack him. When someone is active on the battlefield, and there's no way to physically capture him, what do you exp

I've heard stories about small US divisions backed by large, less talented divisions overseas to carry out the rote work. Maybe that's the case here?

I believe the issue is that copying the Atlas directly would not be permitted, but using it as a research source would be allowed.

I think PhoneGap is doing great work, they're obviously getting better, and I don't mean to diminish what others have poured so much effort into. But, are there any successful apps made with PhoneGap? Writing apps in HTML5 is constantly hyp
