An unfortunate side effect of the rising popularity of Apple’s ARM-based computers is an increase in unportable assembly code which targets the 64-bit ARM ISA. This is because developers are writing these bits of assembly code to speed up their programs when…

Thanks to the C language standard, it's trickier than it seems.

Exploring the world of Zig and Deep Neural Networks

In my previous article on polymorphic allocators, we discussed some basic ideas. For example, you’ve seen a pmr::vector that holds pmr::string using a monotonic resource. How about using a custom type in such a container? How to enable it? Let’s see.
The…

An introduction to using SIMD with Zig

I read a blog post by Alex Muscar, “Beautiful Binary Search in D”. It describes a binary search called “Shar’s algorithm”. I’d never heard of it and it’s i…

The latest major version of the GNU Compiler Collection (GCC), 13.1, was released in April 2023. Like every major GCC release, this version will bring many

performance-degrading usage pattern

Making performant dynamic manual memory management in C feel almost like garbage collection.

This is the Part 2 of a series. Feel free to read the prequel for more context: Building the fastest Lua interpreter automatically Building a good VM for a dynamic language takes a ton of engineerin

It is often said that C++ is a great language for low latency systems, such as high-frequency trading, audio processing, and video games. But what exactly do we mean by "low latency"? How is that different from "high performance"? And what makes C++ a great…
