No NSCoder Night for me tonight!

I’d like to make it to NSCoder Night tonight, but I won’t be able to as I’ll be looking at a new place. Wish me luck, and have fun everybody!

Build LLVM and clang!

I’ve talked about the LLVM Compiler Infrastructure in the past, but what I haven’t talked about yet is just how easy and quickly you can build it on your own Mac running Leopard! This is a great way to get into hacking on compiler lexical analyzers and parsers, code generators, optimizers, and so on. What’s […]

CocoaHeads Silicon Valley at Apple on Thursday, Apple 17, 2008

The next CocoaHeads Silicon Valley meeting will be on Thursday, April 17, 2008 — that’s tonight! — at 7:30 in the De Anza 3 auditorium at Apple. That’s just inside the south side of De Anza 3, right across Mariani Avenue from Apple’s Infinite Loop campus in Cupertino. See the web site for directions. This […]

NSCoder Night Silicon Valley (and hopefully elsewhere)

I’ve been toying with this idea for a while now, and now that Leopard is coming out, it’s finally time to make it happen! I call it NSCoder Night! (Major thanks to Scott Stevenson for coming up with the name!) Here’s the inaugural announcement: NSCoder Night Silicon Valley will be having its inaugural get-together between […]

LLVM Developers’ Meeting 2007-05

The LLVM Compiler Infrastructure is a great technology that came out of the computer science research community and can be used to develop extensible compiler platforms. Among other things, it provides a platform-independent assembly and object code (the “low level virtual machine” that its name is taken from), and a great object-oriented compilation, linking, optimization […]

Unit testing Cocoa user interfaces: Cocoa Bindings

About a year ago, I wrote about unit testing target-action connections for Cocoa user interfaces. That covers the traditional mechanism by which user interfaces have typically been constructed in Cocoa since the NeXTstep days. However, with the release of Mac OS X 10.3 Panther we’ve had a newer interface technology available — Cocoa bindings — […]

It’s not the dynamic dispatch!

Joel has decided to blame the use of dynamic dispatch for Ruby’s speed issues: Without knowing much about the implementation of Ruby, I would guess that the biggest issue is around late binding and especially duck typing, which prevents type inference or strong typing, which means that function calls will always be slow because you […]

Unit testing Cocoa user interfaces: Target-Action

It’s really great to see that a lot of people are adopting unit testing for their projects and dramatically improving their quality. Test-driven development and agile development methodologies built around it are really taking off. However, a lot of people still feel that their user interface is difficult to test through code, and either requires […]

Steve Yegge describes what’s wrong with Lisp

Steve Yegge, Lisp is Not an Acceptable Lisp: You’ve all read about the Road to Lisp. I was on it for a little over a year. It’s a great road, very enlightening, blah blah blah, but what they fail to mention is that Lisp isn’t the at the end of it. Lisp is just the […]

Xcode: Debugging Cocoa application unit tests

A couple weeks ago as part of my Unit Testing Series I talked about how to use Xcode to write unit tests for Cocoa frameworks, debug unit tests in Cocoa frameworks, and write unit tests for Cocoa applications. However, I haven’t yet described how to debug your unit tests in Objective-C Cocoa applications. I’ll take […]
