I found the new Apple TV UI to be a significant improvement, for what it's worth.

Long-term research isn't in Apple's DNA. They did it before, and it almost ended up killing them (cf. Knowledge Navigator). They know this fact. Apple has been forthright about saying that they are a company that takes technologies that are

This shouldn't be done at the HTML5 level, but at the codec level. HTTP Live Streaming already provides a perfectly serviceable way to do exactly this: provide multiple streams at different bitrates and let the media library choose which is

Sure, I'll do a deep dive here. Doing high-performance scrolling is a hard problem. You just can't do it in HTML, at all. Native code is not a silver bullet. If you're implementing a table view cell, the newbie approach is to just put subvi

I'm the iOS developer on the Khan app, and not having to maintain a codebase for multiple platforms is one of the main reasons why we went with jQuery Mobile. Khan Academy has a lot of custom logic (badges being awarded, points being accrue

But of course, doing pen-style operations instead of declarative markup is precisely what gets you the speed and fluidity of a native app. When you open a video with many subtitles in the current iPad app, the UI freezes for a couple second

They are coming to the iPad app. However they won't be implemented in native code; they'll be jQuery Mobile-based.

Hi—I'm Adam Ernst, the iOS-side developer of the Khan app. Your assessment of the app's hybrid nature, and the performance problems that result, is correct. We know that the performance is subpar, and it wouldn't have been much more work fo

Congratulations Samuel, and good luck!

Huh, interesting. I'd bet that this is a bug. The only other explanation I can think of is that push notifications can take about 3-5 seconds to be delivered as they are routed through Apple's servers. If these are long-poll HTTP requests d

Thank god. I have worked extensively with cocoa-websocket and socketio-cocoa and they are a complete mess. Square has done a lot for iOS open source, with their unit test framework and other libraries and now this.

He's using Chrome (see the screenshot). In my experience Chrome is much quicker to interpret a horizontal scroll as a back/forward gesture; Safari implements a good difference between them (as you describe).

Yeesh. According to this chart: http://nordsc.com/ext/classification_of_http_based_apis.html Sharefile is not even a HTTP API (since it doesn't use HTTP methods correctly). For security purposes, authentication can be further increased b

A great point. Our brains parse "no study has found any long-term benefit" as "studies have found no long-term benefit", which is not accurate.

I'm not sure quite where you're going. You agree that having a client construct its own URLs from IDs is brittle. But then you propose an API to turn photo IDs into URLs—but that service itself lives at a particular URL, and is equally subj

As it turns out, it’s just HTTP requests. The alarm bells should be going off now. So you’re telling me that the part of the O.S. that runs as root and replaces system files is downloaded via unsecured, unauthenticated HTTP? Yup. Well, I'

Apple was nice enough to call me on the telephone to discuss my rejection. They wouldn't say why auto-renewable subscriptions can't be used by non-publishers. My suspicion is that they want to prevent app authors from using a SaaS-like mont

by adamjernst 15y ago
I too have been bitten by this. What makes it truly annoying is that it isn't documented anywhere publicly, so beware! You are not allowed to build a business on auto-renewable subscriptions, unless you are a large publisher.

The cars they hire are still regulated as non-street-hail transportation--a livery cab in NYC, for example.

The idea is that ones who seize good opportunities will stay in business, and those that don't (offer Wi-Fi in this example) will eventually go out of business without the need for laws.

As someone who works on their computer all the time, I find it remarkable that so many coffee shops in NYC still don’t provide free Wi-Fi. Probably because they don't want you there using your laptop! I avoid coffee shops that are overc

True. However I should point out that cleanup and shutdown is pretty minimal: it's killed without warning. (I don't know if you even get a signal handler called.) A hibernating app is not allowed to execute any code.

Knowing the economics behind it, I'm all for dynamic pricing even though it does feel like a ripoff to me personally. I'd be very interested, though, to know how much of the increase (~6x normal according to a screenshot on their site) is

Mike, did your refusal to sign the contract (despite your continuing work on the project) have anything to do with the delay in payment? Did you attempt to modify the deadline to a future date, and if so did they refuse to accept that versi

This is a well-meaning gesture and I'm sure that Facebook can't track transactions just because they commissioned the card. Still, I can't imagine security researcher types are going to like the idea of making daily purchases with a card co
