| | | | | My colleagues recently wrote a great post on the Netflix tech blog about a tough performance issue they wrestled with. They ultimately diagnosed the problem as false sharing, which is a performance problem that involves caching. I'm going to take that post and write a simplified version of part of it here, as an exercise... | |

| | | | | In this post, we are going to take a deep dive into pointer tagging, where metadata is encoded into a word-sized pointer. Doing so allows us to keep a compact representation that can be passed around in machine registers. This is very common in implementing dynamic programming languages, but can really be used anywhere that additional runtime information is needed about a pointer. We will look at a handful of different ways these pointers can be encoded and see how the compiler can optimize them for diff... | |

| | | Pointers can be a daunting concept for those new to the C programming language, but they are a very powerful tool that can greatly improve the efficiency of your code. In this article, we will demystify pointers and explain how they work, why they | ||
