This is a continuation of an earlier post called, Division By Zero Exploration, which was a continuation of an even earlier post, Division By Zero. In the exploration post, I concluded that, if dividing by zero is valid, then, “it is basically possible to make anything equal anything”. Further thought has lead to an additionalContinue reading “Division By Zero Exploration pt 2”

Structured Bindings and replacing by reference
C++ 17 has Structured Bindings, what they do is create a temporary object and provide access to the object’s members locally. What happens is we create a temporary S object, and then copy the values memberwise into the binding structure. x now equals 5 and b equals 3.2. the S instance goes away. Since functionsContinue reading “Structured Bindings and replacing by reference”
Asymptotic Movement
I discovered a GDC talk on a topic called: Asymptotic Averaging. This is sort of a form of interpolation, and can be used to eliminate jerky motions – in particular, they focus on camera movement. Naturally, when you want to change a camera’s direction, you just set the direction. However, if you are doing thisContinue reading “Asymptotic Movement”
Fold Expressions and Lamda Overloads
C++17 has a powerful template feature – Fold Expressions – that combines with a C++11 feature – Parameter Pack. This allows us to do away with C-style variable arguments (variadic functions). I introduce Lamda Overloading as well, to work with these two concepts in a wonderful way. First off, the Parameter Pack. This is aContinue reading “Fold Expressions and Lamda Overloads”
Division By Zero Exploration
This post isn’t so much about programming as much about an earlier post about Division By Zero. So, I thought, if the reciprocal operation to 1 / 0, 0 / 1, is valid, then maybe division by zero can be postponed and considered later. Similar to the imaginary concept, i or sqrt(-1). Using just fractionContinue reading “Division By Zero Exploration”
Super Simple Lambda Thread Pool
I wanted to quickly create a thread pooler that could be passed lamdas. Turns out it’s super simple. Here are the main things I wanted to accomplish: pass lamdas as tasks to be executed asap. be able to wait for all tasks to execute create a bunch of threads at initialization and them have thenContinue reading “Super Simple Lambda Thread Pool”
Division By Zero
So we all know that dividing by zero is an error in programming, but do you know why? It turns out that it not really an error as much as a math problem, and not so much a problem as much as a thing. Here’s how it goes according to my understanding: A function y=Continue reading “Division By Zero”
C++ lambda and how the world is different now
So, there was the world of C++ before the lambda. And now there’s the world of C++ since the lambda – and I’ve got to say, if you aren’t using lamdas, then your’e probably still in the C++ stone age. This post is going to be all about lamdas and how rad they are. DoContinue reading “C++ lambda and how the world is different now”
Staggering Vector
So in my current game project, I want to have a some what real-time simulation in which stuff happens. This boils down to doing stuff periodically in a game loop. In my game, the game loop is running at 30 frames per second. I was having problems maintaining this rate, and I did not wantContinue reading “Staggering Vector”
SOA sorting
So in my current project, I’m using a library which uses a programming methodology called, SOA, or structure of arrays, which is different than OOP ( object-oriented-programming). Basically, in SOA, instead of having an object with 10 properties, and a vector of those objects, you have a structure with 10 vectors each containing one property.Continue reading “SOA sorting”
