In April I’ll be going to two iPhone/iPad developers conferences: iDev 360 in San Jose and Voices that Matter in Seattle. (I’ll be speaking at 360 iDev. For the Seattle conference I’ll be playing the part of a local, since, well, I live in Seattle.)

Tim Bray on being well-informed or not: “This might signal a new kind of stratification in society.”

Crazy Apple Rumors Site: “It’s a Cinderella story.”

Peter Hosey: “Welcome, new Cocoa or Cocoa Touch programmer. Here are some things you will need to know.”

Lukas Mathis: “Eventually, you will find yourself in a position where your application contains features it should not. Even if you’ve been vigilant, this will happen.”

Cocoia posts the good stuff, as always.

Macworld: “For Apple, it’s not about killing off tinkerers, but ensuring that not everybody who wants to use a computer has to be a tinkerer.”

Tyree Apps: “I’ve created a little view controller that lets a TapLynx app offer the user a quick way to snap a photo and then email it to someone without ever leaving the TapLynx based application.”

One of my favorite parts of TapLynx is that it’s extendable: you can create new views with new features. (Note to programmers: TapLynx is a static library. You still use Xcode to build apps, though TapLynx makes it so you write code only if you want to.)

The Omni Mouth: “We want to bring all five of our productivity apps to iPad: OmniGraffle, OmniOutliner, OmniPlan, OmniFocus, and OmniGraphSketcher.”

I’m especially a fan of OmniOutliner — and I want an outliner on iPad. This is great news.

Mike Ash: “Using a technique called method swizzling, you can replace an existing method from a category without the uncertainty of who ‘wins,’ and while preserving the ability to call through to the old method.”

This is interesting information that you should read and never use.

Fraser Speirs: “Those of us who patiently, day after day, explain to a child or colleague that the reason there’s no Print item in the File menu is because, although the Pages document is filling the screen, Finder is actually the frontmost application and it doesn’t have any windows open, understand what’s happening here.”

Macworld: “At the heart of the iPad lies a tiny sliver of silicon. A game changer within a game changer.”

Playing with Shapes: “I’m just as anxious as anyone else to start designing for the iPad. I always have to start with paper.”

UsabilityPost: “When you scroll, the content scrolls without any interruptions and lag — it’s very, very smooth. Why is this so important? It’s important because this level of responsiveness blends the borders between analog and digital media.”

Scripting News: “Is it possible to create an iPad-like platform that has none of the drawbacks of Apple’s offerings?”

Excellent question. I think that in ten years, most computers will be iPad-like.

I don’t know any developers that like the App Store review system. I don’t. But I’ve never seen even the barest hint that freedom of speech is otherwise limited. And I’m hyper-sensitive to that, completely allergic to anything that I think would hurt that freedom.

Joe Hewitt: “iPad is an incredible opportunity for developers to re-imagine every single category of desktop and web software there is. Seriously, if you’re a developer and you're not thinking about how your app could work better on the iPad and its descendants, you deserve to get left behind.”

chockenberry: “There’s an inherent benefit to only doing one thing at a time: the load of worrying about other tasks is lifted. Knowing that there isn’t anything else competing for your attention is quite liberating.”

Totally right on. It’s one of the reasons I could see myself using an iPad more than my laptop. (I use a desktop Mac for development.)

Mike Rundle: “Most people are not power users, they mainly consume content using their computer rather than produce it. When they produce content it’s more casual: posting to Twitter, updating Facebook, writing personal blog entries and notes, uploading photos.”

Steven Frank’s blog post will be on the syllabus. Critical reading, if you want to understand what happens next.

Cult of Mac: “I thought it would be interesting to find out what some Mac and iPhone developers make of the iPad.”
