At some point, if you’ve done multithreaded programming, you’ve probably used a mutex (or some other locking mechanism). Locks are relatively straightforward to understand and use (“lock this thing before accessing your data and unlock it w…

Imagine this: you’ve got some value, x, that you want to ensure is at least 1. That is to say, you want to ensure its minimum value is 1. So, being the smart, experienced programmer that you are, you write the following: You give yourself t…
A while back I was working on a programming language idea and while I haven’t made any progress on it in ages, I really liked the string design that I came up with. I don’t know that any of the ideas are original, but I haven’t seen anythin…

(This post follows Part 1: 32-bit floats and will make very little sense without having read that one first. Honestly, it might make little sense having read that one first, I dunno!) Last time we went over how to calculate the results of t…

A thing that I had to do at work is write an emulation of the FMAdd (fused multiply-add) instruction for hardware where it wasn’t natively supported (specifically I was writing a SIMD implementation, but the idea is the same), and so I thou…
C++17 added support for hex float literals, so you can put more bit-accurate floating point values into your code. They’re handy to have, and I wanted to be able to parse them from a text file in a C# app I was writing. (Before reading this…
