Please Take an Economic Class… or Two.

I am so very TIRED of seeing stupid posts like the one below. To me it shows one area where public education has completely failed our children by not teaching them important things like basic economics. This leads to our kids having this grossly fairy tale-like, over simplified view of economics. Our kids end up … Continue reading Please Take an Economic Class… or Two.

A Better RegularExpression

As promised a while ago I've sat down and hammered out a better replacement for Swift's NSRegularExpression class. As I said then, NSRegularExpression is not actually a Swift class but rather an Objective-C class that has been bridged over to Swift via Swift's excellent ability to interface with C, C++, and Objective-C libraries directly. But … Continue reading A Better RegularExpression

Scripting with Swift

Did you know that, just like Python, Bash scripts, etc., you can run a Swift source file right from the command-line as if it was an already compiled executable? You betcha! 😎 The Swift REPL program honors the SHEBANG line in a Swift source file. #!/usr/bin/swift import Foundation print("") print(" Int8 - size: \(MemoryLayout<Int8>.size); stride: … Continue reading Scripting with Swift

Avoiding a Swift NSRegularExpression Pitfall

Until Swift gets a native regular expression class of it's own we are stuck with the Objective-C version - NSRegularExpression. The Objective-C version is very capable and works very well but it's important to remember that it is working on Objective-C NSStrings which, unlike Swift's native Strings, are based on the UTF-16 encoding. What this … Continue reading Avoiding a Swift NSRegularExpression Pitfall

Fastest Way To Get The Time

So, for my 6502/6510 emulator project I've been trying to figure out the best (read that, "fastest") way to get the time with nanosecond resolution. I need this because the North American version of the Commodore 64 ran at 1.02MHz (1,022,727Hz) and so that means the clock "ticks" every 977.8 nanoseconds. And that's just for … Continue reading Fastest Way To Get The Time

USE AT YOUR OWN RISK - I provide absolutely NO WARRANTY, implied or otherwise, with this what so ever. EDIT: 2020-09-22 - You will probably … Continue reading Swift 5.3 on Odroid C2
