ChaiScript Tutorial (5.5) – Global Variables in ChaiScript

Besides calling ChaiScript functions from C++. You can also access global variables from C++. Global Variables in ChaiScript Unlike most languages, where weather a variable is global or not is defined by if the variable exists in the root scope. Such as the following in C++: ChaiScript uses the global keyword to specify if a variable...

Building sfeMovie on MSYS2 – A Hacky Way

I'm working on a project to automatically generate Groove Coaster beat maps(?) using machine learning. To gather traning data. I need a desktop application that plays video of other's playing Groove Coaster and I and my friend pressing the appropriate button on a DS4 controller. Getting DS4 button press is easy. SFML has that handled....

Programming in C++ without if/else/for/while/etc..

Recently on of my friends challenges me to write a game in C++ without using any branching and looping expressions. It's really not difficult at all. I could write a game in C and compile it with the M/o/Vfuscator then disassemble it, put all the assembly instructions into my C++ code. Bobs your uncle, challenge done. But what's the...

ChaiScript Tutorial (5) – Calling ChaiScript Functions from C++ and vise versa

With the really limited functionality ChaiScript has. There must be a way to expand it's ability. In this tutorial, we are going to expend ChaiScript's functionality by calling C++ functions in ChaiScript and the reverse. Calling C++ functions in ChaiScript To call C++ functions in C++ from ChaiScript requires 2 steps. Register the C++ function to...

Rent on OpenCL on FPGAs From a Point of View of a Software Developer

This is why I haven't post any ChaiScipt tutorial recently. I'm busy on a project to bring OpenCL into OpenCV on a Cyclone V SoC Development Board. There are a lot of reports and articles about how FPGAs are so powerful that they can outperform GPUs. And that OpenCL can unleash FPGA's full performance in...

Install AMD HIP on Nvidia platform

HIP is sort of AMD's version of CUDA. It allows developer to write CUDA-like code and build for either AMD or NVIDIA GPUs. But the current version contains a small coding error that prevents HIP from working on NVIDIA GPUs. Installing hip_nvcc on Ubuntu 16.04 using the ppa won't work either. That sucks. Here is...
