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

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
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.
