Integrated assembler improvements in LLVM 19
Within the LLVM project, MC is a library responsible for handling assembly, disassembly, and object file formats. Intro to the LLVM MC Project, which was written back in 2010, remains a good source to understand the high-level structures. In the latest release cycle, substantial effort has been dedicated to refining…

Trivia About Rust Types
Preface (by Jimmy Hartzell) I am a huge fan of Jon Gjengset’s Rust for Rustaceans, an excellent book to bridge the gap between beginner Rust programming skills and becoming a fully-functional member of the Rust community. He’s famous for his YouTube channel as well; I’ve heard good things about it (watching video…

Automatic Video Editing
Amongst the many consequences of COVID-19 has been the suspension of in-person talks: suddenly, people like me have had to think about how to produce prerecorded videos. In this article I’m going to explain what I’ve come to understand about video recording and the “automatic video editing” technique I’ve used for…

I wrote a Pong game in a 512-byte boot sector
written by - Akshat Joshi Sometime back, I set myself a crazy constraint: Load only one thing at boot - A Pong game that fits in one floppy disk sector — 512 bytes. Why would I build this? I have played with Operating Systems and their workings by customizing them and tweaking their

Building better software with better tools: sanitizers vs. Valgrind
We often have to write code using permissive programming languages like C and C++. They tend to generate hard-to-debug problems that can crash your applications. Thankfully, many compilers offer "sanitizers". I discussed them in my post No more leaks with sanitize flags in gcc and clang. I strongly encourage the use…

Modern C++ for C Programmers
2018 is an exciting time to be a programmer, with so many good “full service” programming languages to choose from: C, C++ 2017, Go, Python, Rust and who knows Swift too. Programming languages are complicated beasts - even the simplest languages have specifications that run (or would run) in the hundreds of pages, and…

The limitations of sampling profilers
Perf is probably the most widely used general purpose performance debugging tool on Linux. There are multiple contenders for the #2 spot, and, like perf, they're sampling profilers. Sampling profilers are great. They tend to be easy-to-use and low-overhead compared to most alternatives. However, there are large…

How much memory does a graph take?
We need a fast way to query multiple potentially large sets of data on-demand at interactive speeds. Sometimes the easiest solution to a hard problem is to build the right tool for the job.
