Undefined behavior (UB) is a tricky concept in programming languages and compilers. Over the many years I've been an industry mentor for MIT's 6.172 Performance Engineering course, An excellent class that I highly recommend. It's very thorough and hands-on, at the expense of also requiring a lot of… read more

A beginner-friendly introduction to compilers: follow along as we build a compiler from scratch, or fork the code on GitHub and add your own optimizations too! In this episode: value numbering helps track how values are used in the program. Last time on Compiler Adventures, we implemented constant p… read more

A beginner-friendly introduction to compilers: follow along as we build a compiler from scratch, or fork the code on GitHub and add your own optimizations too! In this episode: eliminating no-op instructions. What part of computer science feels most like arcane magic? I'd say compilers. "The magical… read more
