I am never good at using Git.

But it’s not my fault. Git has too many commands, and I am not a command line guy. That’s why I usually use SmartGit, a Git software with user interface that supports Mac.

However, there are times when you have to run on the command line (eg. scripting or you just want to be real fast).

These are my common use cases during development work flow. I don’t cover everything, or advanced stuff.

With every iOS updates and new release of devices from Apple, there are more things developers have to do.

In order to support these new devices, you first need to understand these devices.

Mountain Lion comes with a Wifi Scanner that is much better than you expected.

I tried out KisMAC at first, but couldn’t get it working. I hate reading their lengthy newbie guide.

Then I found a gem in Mountain Lion.

UPDATE: For AFNetworking 2.0, refer to this tutorial instead.

AFNetworking is the choice for iOS/Mac developers when it comes to choosing a HTTP library.

ASIHTTPRequest used to be the choice, until 2011 when it became inactive.

I am one of the many who is forced to switch camp.

This is a review of the book Good Strategy, Bad Strategy.

The first 20% of the book is still okay. But I could not read beyond that, as it is long winded, and used too many examples from US Military strategies.

Nonetheless, here’s what I learnt:

I swear this is the most common error I have seen whenever I upload an iOS binary.

Error: application executable is missing a required architecture armv6

It occurs every time after Apple release a new iPhone (or architecture type).

This post is a guide to updating existing app for iPhone 5.

As you already knew, the new iPhone 5 introduced a taller screen at 4 inch, while all iPhones before is at 3.5 inch.

There are a couple of steps that you have to do to support the taller screen, and it really depends on how you develop your app in the first place. You might use all of the techniques below, or none.

These techniques are inspired by answers on Stackoverflow. The result is a Device class I created at https://gist.github.com/3926123

I spent about 2 weeks using Scala, before concluding that I hate the language.

When I first wrote the first beginner guide to Scala, I was in awe, and yet feeling a tinge of uneasiness.

Then I spent a few days creating a Scala web application, resulting in a subsequent random guide to Scala programming.

After I am done with the project, I know I would not start another project in Scala at my own will.

This is a continuation to a short Scala tutorial and Scala+Play Development Guide.

During the development of a project using Typesafe Stack (Scala + Akka + Play!), I learnt quite a few things about Scala and the Play framework.

This is a guide on using Typesafe Stack (basically on Scala + Play! Framework).

It covers installation, start a project, setting up Eclipse and Git, then deploying to Heroku.
