Concurrent programming requires synchronization. We can’t have more than one thread accessing data at the same time; otherwise, we end up with a data race. The most common solution is to wrap […]
How does a mutex work? What does it cost?
mortoray
Over 20 years of programming. From video games to communications; science to finance; compilers to business processes. Too many languages to even track anymore.

Keeping tabs on shady internet authorities — What is Certificate Transparency?
Did you know somebody else could steal your domain name? Even if you’ve properly secured your site and gotten the right security certificates, it’s still possible some people get to the wrong […]
How I use `variant` in the Leaf compiler
Variants are data types that can store different types of values in them, as opposed to one fixed type. In contrast to a generic object or an untyped variable, there is a […]
Core Layout Protocol API (UI Engine)
Let’s get into some technical details about how a layout engine works. We assume that we have a tree of elements that comprise the UI. Starting from the root node, we request […]
