Lisa Source Code: Clascal Evolution

Sunday, February 5, 2023

Here’s another interesting thing I’ve learned about Clascal and Object Pascal: It went through exactly the same evolution from combining object allocation & initialization to separating them that Objective-C did a decade later! In early 1983 Clascal, classes were expected to implement a New method as a function returning that type, taking zero or more […]

In addition to run loops, threads (both Cocoa and POSIX) and operations, Snow Leopard adds **Grand Central Dispatch** (GCD), a very lightweight way to represent units of work and the style of concurrency they need, and have the system figure […]

Welcome to Snow Leopard!

Sunday, September 6, 2009

Last week, Mac OS X 10.6 Snow Leopard was released! Snow Leopard represents a lot of hard work by a lot of folks at Apple and at seeded third-party developers, and it really shows. Now that it’s shipped, I can actually talk about some of the especially cool things this release has for developers.

Friday, August 7, 2009

Given my reaction on Twitter, several people have asked me to write a more in-depth rebuttal. I’ve already addressed when and why you should use Objective-C 2.0 properties and dot notation in […]

When to use properties & dot notation

Wednesday, May 27, 2009

I listened to a recent episode of the [cocoaFusion:][1] podcast about properties and dot notation today.

In a few weeks, it will be **four years** since Mac OS X 10.4 Tiger was first released. That was the first release to include Core Data. It will also be about **one and a half years** since Mac OS X 10.5 Leopard was released, with significant enhancements to the Core Data API. It’s pretty […]

The time is upon us once again — WWDC time! As I have the past few years, I’ll be in San Francisco all week, staying at the Hotel Kabuki in Japantown. And of course, I’ll be around the conference all week — especially in the labs. Come by and say hi, and I’ll be happy […]
