Four short links: 6 December 2010

By Nat Torkington
December 6, 2010

Apple I Basic as Mac OS X Scripting Language -- great hack. The “apple1basic” executable is a statically recompiled version of the original binary. All code is running natively. It plugs right into UNIX stdin and stdout. You can pass it the filename of a BASIC program to run. You can run BASIC programs like shell scripts. (via Hacker...

Posterous: The Copy-and-Post Revolution in (Micro) Blogging

By Mark Sigal
November 4, 2009

A friend of mine, who has achieved repeated success in high-tech startup land, said that if you want to be successful, focus on segments where <10% of the crowd currently adopts the solution, and by virtue of dramatically simplifying the approach, you can toggle adoption rates to closer to 90%. Enter Posterous, a micro-blogging tool (it's free) that does a few things really well.

Making an iPhone vibrate requires nothing more than a simple call to Audio Services. Deciding on when your application should buzz is a different matter. The code for producing that short buzz effect is this:

Opt-In Complexity

By Chris Adamson
January 16, 2009

It's an interesting trait that the Mac and iPhone stacks work this way, opting in to complexity and keeping the higher-level APIs sparser and simpler, and you have to wonder whether it's a conscious design decision or a happy accident.

Thinking about table selection: Persistent or Active?

By Erica Sadun
January 9, 2009

A colleague recently had his application rejected from App Store because he used what I can only call a noun-verb approach. He allowed items in the table to be selected, and highlighted upon selection, and then provided buttons that used that choice to perform an action. His application was rejected, with the rejection citing the following from the iPhone Human Interface Guidelines:

We Probably Aren't the Target Market for the iPhone Anymore

By Dave Aiello
January 9, 2009

I've been cheerleading for iPhone tethering since this past summer. In spite of that AT&T and Apple have failed to announce it. With Macworld Expo 2009 almost over, I'm beginning to wonder if Apple considers this feature a maybe-someday feature...

Is Tweetie an iTunes App Store Anomaly?

By Dave Aiello
January 5, 2009

I am really impressed with Tweetie, the multi-account Twitter client iPhone application. I find it bizarre that Loren Brichter (the developer) has created a true, multi-account Twitter client for the iPhone and there's still not a native application for the...

Defining legal input characters

By Erica Sadun
January 2, 2009

I sometimes use a little trick to ensure that a UITextInputField only accepts a certain subset of characters. Say for example, you want to ensure that a user enters only letters and spaces. A UITextField delegate can catch each character as its typed and decide whether to add items to the active text field. Here's how.

The App Store Effect

By Paul Kafasis

Snapper-brand lawn mowers are expensive. Many Snapper products cost thousands of dollars, and even their simplest push mower is hundreds of dollars more than some competing products. Snapper lawn mowers are not cheap. What they are, however, is reliable. They're...

Converting Points and Rectangles to Strings and back

By Erica Sadun
December 19, 2008

Two core graphics structures, the CGRect and the CGPoint, play a large role in iPhone development. They are used to position items on-screen and to set their size. Every time you use a UIView, you can work with its frame, its center, and its bounds--all of which use these two structures to handle geometry. Here's a quick review of the structures in question.

Why Didn't Apple Declare Victory at Macworld Expo?

By Dave Aiello
December 18, 2008

Like everybody else, I saw Apple's announcement that they would end their participation in Macworld Expo after Macworld Expo 2009 and was not surprised. The real issue about this and all trade shows is do they make sense in 2009,...

The case of the Missing MapKit

By Erica Sadun
December 5, 2008

While wading through the new 2.2 Frameworks, I suddenly noticed that MapKit, once a Private Framework was missing in action. MapKit, which was available until SDK 2.1, offered all kinds of utterly yummy features including Trip Players, Traffic tiles, Route Views and more. So what happened to MapKit?
