Installing Ruby 1.9.2 or Ruby Enterprise Edition in OS X Lion with RVM

Mon, 31 Oct 2011 12:45:38 -0600

Using MacPorts you can install Ruby Enterprise Edition, as well as Ruby 1.9.2 for the local user in OS X Lion while having Xcode 4.2 installed by using “Apple’s version of gcc 4.2.”

Note: The reason I mention Xcode 4.2 is that Apple removed gcc-4.2 in Xcode 4.2 for llvm-gcc-4.2.

Prerequisites:

OS X Lion (tested in 10.7.2)
Xcode 4.2
rvm 1.9.1
MacPorts 2.0.3

Execute the following commands:

$ sudo port install apple-gcc42

$ export CC=/opt/local/bin/gcc-apple-42

then

rvm install 1.9.2

rvm use 1.9.2 —default

rvm install ree

rvm use ree —default

Note: Ruby 1.9.3 was just released and should not require apple-gcc-42

Developing RESTful iOS Apps with RestKit

Fri, 29 Apr 2011 17:00:41 -0600

RestKit is an Objective-C framework for iOS that aims to make interacting with RESTful web services simple, fast and fun. It combines a clean, simple HTTP request/response API with a powerful object mapping system that reduces the amount of code you need to write to get stuff done.

Distribute Ad Hoc Applications Over the Air (OTA)

Mon, 21 Feb 2011 10:46:19 -0700

Distribute Ad Hoc Applications Over the Air (OTA):

If you’ve been through the distribution process of an Ad Hoc application, you can appreciate the challenges of getting a build installed on someone’s device. From the differences of working with users on Windows versus Mac machines, to explaining how to import an Ad Hoc provisioning file and the associated build into iTunes, this process is anything but a walk in the park.

In this post I’ll walk you through the steps of deploying Ad Hoc builds over-the-air, where users simply point the Safari web-browser (on their iPhone) to a link and tap to install the provisioning file and associated application.

Excellent talk at TED about how video games reward the brain.

We’re bringing gameplay into more aspects of our lives, spending countless hours — and real money — exploring virtual worlds for imaginary treasures. Why? As Tom Chatfield shows, games are perfectly tuned to dole out rewards that engage the brain and keep us questing for more.

Git Immersion:

Git is a powerful, sophisticated system for distributed version control. Gaining an understanding of its features opens to developers a new and liberating approach to source code management. The surest path to mastering Git is to immerse oneself in its utilities and operations, to experience it first-hand.

Defensive Coding in Objective-C

Sat, 08 Jan 2011 12:41:00 -0700

Defensive Coding in Objective-C:

When programming in a C-descended language like Objective C, there are many things that can easily go wrong. To avoid the worst of these errors, programmers have come up with various coding conventions that make it harder to cause such bugs. We’re not talking about indentation or spacing, but rather about “mini-patterns” that ensure certain errors are caught more easily.

Unit Testing in C++ and Objective-C just got easier:

CATCH is a brand new unit testing framework for C, C++ and Objective-C. It stands for ‘C++ Adaptive Test Cases in Headers’, although that shouldn’t downplay the Objective-C bindings.

Mac OS X Debugging Magic

Mac OS X Debugging Magic:

Mac OS X contains a number of ‘secret’ debugging facilities, including environment variables, preferences, routines callable from GDB, and so on. This technotes describes these facilities. If you’re developing for Mac OS X, you should look through this list to see if you’re missing out on something that will make your life easier.

A successful Git branching model

Mon, 13 Dec 2010 08:38:00 -0700

A successful Git branching model:

In this post I present the development model that I’ve introduced for all of my projects (both at work and private) about a year ago, and which has turned out to be very successful. I’ve been meaning to write about it for a while now, but I’ve never really found the time to do so thoroughly, until now. I won’t talk about any of the projects’ details, merely about the branching strategy and release management.

Version control for solo Mac developers

Version control for solo Mac developers:

In this post, I’ll take a quick look at how to keep your projects in git and how to manage that easily on the Mac. More importantly though, I’ll take a look at why you’d want to do this, even if you’re the only developer, you don’t need to share your code, you don’t have formalized releases that need to be tagged and you already have a backup system protecting your code.
