Swift – First Impressions

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. ūüėé 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 […]

Taking the Swift Plunge

Okay… So… I think I’m finally ready to take the plunge and start learning the Swift Programming Language in earnest. I’ve been watching it and starting with version 5 there is finally enough there for me to get excited about. But this isn’t going to be easy for me. Not like it was when I […]


I’ve made a major milestone in my personal project Rubicon. ¬†I’ve gotten it where it will build on Linux as well as Mac OS X. ¬†More info is in the readme file. ¬†Check it out:¬†https://github.com/GalenRhodes/Rubicon

Always an Easier Way

Previously in¬†Avoiding an Objective-C Pitfall¬†#1¬†I discussed a more stable way of creating singletons in Objective-C. ¬†As with all things in the world of Apple there’s always an easier way and that way comes to us via two very powerful yet unnoticed (in the Windows and Linux communities at least) APIs that Apple has contributed to […]

Objective-C and Exceptions

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 […]

Avoiding an Objective-C Pitfall #1

Below is a very commonly used design pattern in Objective-C. It’s the typical¬†Objective-C “Singleton Pattern” because it does just that. ¬†Returns a singleton of the class it belongs to. ¬†If we take a look at an example that uses it we can see it in action. The¬†“@synchronized(self)” statement ensures that only one thread at a […]

Thoughts on GNUstep

For those that don’t know GNUstep is a project that started many years ago to help bring Objective-C to the masses using operating systems other than Mac OS X macOS. ¬†Actually, Objective-C already existed on any platform that had access to the GCC compiler suite but what GNUstep sought to do was bring the primary […]

Identifying the Odd Electronic Component

If you ever come across an electronic component that looks like this (a small electrolytic capacitor or radial inductor) with simply the letters “HDX” and rattles if you shake it (even a little bit) then I’ll save you some trouble. ¬†It’s called a “vibration switch”! ¬†And, as you might guess, it’s a SPST switch that […]
