So, one of my other hobbies are retro-computers. Specifically the Commodore 128. I had this computer as a kid and it still holds a strong place in my heart. I recently acquired a Commodore 128DCR on eBay and have been playing with it again. But as with all things retro, there is a strong community … Continue reading Pi1541 Pi-Hat
Taking a look at my activity on GitHub shows that, outside of my day job, I didn't do Jack from June until November last year. 😳 No wonder I was so cranky. All work and no play makes me very restless!
I've started using Jazzy to generate documentation for my Swift and Objective-C projects. If you do development on the macOS platform then I highly recommend using Jazzy. It's by far the easiest to use. Here's a sample: Rubicon ► Extensions ► String ► split(on:limit:)
After playing with Swift a bit here are my first impressions of the language. There is definitely a lot to like about it! There's also a few things that annoy me. 😎 But first I'll start out with a giving you a 1,000 foot overview of the language itself. Syntax aside, Swift and Objective-C 2.0 (as … Continue reading Swift – First Impressions

Not like it was when I … Continue reading Taking the Swift Plunge
The formatting really didn't copy over well. Read the actual page here: https://github.com/GalenRhodes/LockSpeedTest/blob/master/README.md -fobjc-arc-exceptions My current use of this is to test if there was any overhead involved with using the clang -fobjc-arc-exceptions flag to ensure that memory isn't leaked when exceptions are thrown in Objective-C. Basically I compiled this test without -fobjc-arc-exceptions and ran it … Continue reading Objective-C and Exceptions
I originally posted this on LikedIn back in June, 2017. My high school shop teachers use to drill it into me and my fellow students every day. At least once every day I'd hear one of my shop teachers tell someone in the class, "Use the right tool for the job!" Usually this happened just … Continue reading It’s All About the Tools Baby!
