Let me introduce you to the best language you’ve never heard of: Objectivist-C.

Although academic computer scientists have generally dismissed Objectivist-C, it has a zealous following among self-taught programmers and college sophomores.

Objectivist-C was invented by Russian-American programmer Ope Rand. Based on the principle of rational self-interest, Objectivist-C was influenced by Aristotle’s laws of logic and Smalltalk. In an unorthodox move, Rand first wrote about the principles of Objectivist-C in bestselling novels, and only later set them down in non-fiction.

Here’s what you need to know to program in Objectivist-C. [more...]

When you’re getting started with iOS development, it’s hard to figure out those first steps. What developer tools do you need? What are some good tutorials to start with? Where to begin delving into Apple’s thousands of pages of documentation?

That’s why I created iOS Development on 1 Page — a not-overwhelming guide for iOS newbies.

Is there any essential info about iOS development that should be added to iOS Development on 1 Page? Let me know!

Say you want to create a UIView that you’re going to display in multiple places in your app.

Maybe you want to design a custom UITableViewCell or AQGridViewCell. Or maybe you want to create a view controller that can be displayed by several different view controllers in your app. Or maybe you want to create a custom UI widget that shows up multiple times in a view.

Does this mean you have to make the view programmatically? Is it time to break out the setFrame and the addSubview and the setTextColor and the addTarget:action:forControlEvents:?

Nope! You can still design your views in Interface Builder. Here’s how. [more...]

There are a lot of iPhone/iPad examples out there, but surprisingly I haven’t seen one for a common task – using a table view to create a form. Here’s the source code. [more...]

The IOSurface framework lets you pass a reference to an IOSurface – a kind of pixel buffer – from one process to another. Here’s an example of how to pass an IOSurface through a mach port using the functions IOSurfaceCreateMachPort and IOSurfaceLookupFromMachPort. [more...]

• Works on Snow Leopard (with Mail.app running in either 32bit or 64bit).
• After moving a message, automatically selects the following message (instead of selecting nothing).

In the year that has elapsed since I failed to explain why I was using PINE for email, I’ve switched to Apple Mail. Don’t ask.

Well, it’s been alright, but much to my regret the improved latency due to keystrokes only traveling around my local machine — instead of through the interweb and back as was the case with PINE on a remote machine — makes it almost justifiable. Almost. [more...]

For years, iPhoto users have been stuck using a limited number of email clients to send their photos easily. This was mostly remedied by the iPhoto Mailer Patcher, but it left out non-applescript aware applications because, after all, iPhoto uses applescript to interface with them. One of the more notable omissions is Thunderbird.

Finally, this void has also been filled, via the iPhoto Thunderbird Bridge. It’s still quite primitive, but all the basics are there for iPhoto-Thunderbird integration.

If you’re an iPhoto/Thunderbird user, give it a whirl.

NSSpeechSynthesizer, the Cocoa class responsible for giving applications a voice under OS X, is leaky. Creating and destroying thousands of instances of this class slowly consumes all the available memory in a system, leading to degrading performance and eventual application instability.

The disappointing part is that this bug was first noticed almost two years ago. [more...]

The Kineme Quartz Composer patches now have a proper home at http://kineme.net/, including forums, bug reports, comments, and feature requests — complete with voting!

Along with the new site, a few new patches are available as well based on requests from users.
