• Tracking Humidity and Temperature with a BLE Peripheral

    Mostly academic, but still useful and interesting I want to track humidity and temperature data in my apartment. I’m interested to see if there’s a correlation between good quality sleep, good allergy days, and a specific temperature/humidity.

    This project covers a few new things for me, including:

    • Using a Raspberry Pi
    • Electronics
    • Bluetooth LE

    For that reason, I wanted to document here how I worked through the project, mostly for future Andy.

  • Little Cinna

    We got this little Maltese Shih Tzu from Monika’s Doggie Rescue in 2013 shortly after moving to Australia. Although she’s often mistaken for a puppy, she’s 13 years old now. She was given the name Cinnamon and we just shortened it to Cinna.

  • Introducing Arty

    Over the last year I’ve been trying to improve my drawing ability (specifically photo realism). In this time I’ve learned three main things:

    1. There’s no such thing as cheating in art (except stealing).
    2. A corollary to the first point: it’s OK to trace.
    3. All creations go through an “ugly phase”.

    To help me create better art and enjoy the process more, I’ve made an app called Arty.


    Briefly, Arty stays with you beyond just applying a filter. You can use it to create accurate line drawings, zoom in to details, pick out colours and even track how long you’ve been working on your project.

  • Cutting Corners


    Rounding the corners of a view programmatically has been beautifying our screens since May 1981. In UIKit, the so-called “RoundRect” was made easily achievable for developers in iOS 3 with the addition of the cornerRadius property of any CALayer. But like the old saying goes: there’s more than one way to skin the corners off a cat.

    In this post, we’ll take a dive into cornerRadius VS. UIBezierPath.

    Mei Li is a single-screen, message-based app that promotes frequent, but brief engagements. When you first launch the app you’ll meet Min Li and be given an introduction and onboarding, but it’s all in flow. Once you’re setup, Min will start teaching you, and quizzing you.
