How We Built a Vectorized SQL Engine
Using vectorized processing in an execution engine makes more efficient use of modern CPUs by changing the data orientation (from rows to columns) to get more out of the CPU cache and deep instruction pipelines by operating on batches of data at a time.

Audio Processing for Dummies
In my spare time I’m an emergency services volunteer, and one of the tasks our unit has is to run the radio network and keep track of what’s happening. This can be a pretty stressful job, especially when there’s lots of radio traffic, and it’s not unusual to miss words or entire transmissions. To help with a personal…

Rust 2020: GUI and Community
In response to the call for blogs about the vision for Rust for 2020, I’m going to write about GUI. I believe the time is right for a native GUI toolkit written in Rust, and that such a thing would fill a very important niche. There is a demand for performance (which, to me, includes startup time, RAM footprint, and…

How an Optimizing Compiler Works
Optimizing compilers are a mainstay of modern software: allowing a programmer to write code in a language that makes sense to them, while transforming it into a form that makes sense for the underlying hardware to run efficiently. The optimizing compiler's job is to figure out what your input program does, and create…

Notes on Type Layouts and ABIs in Rust
Over the years I’ve found myself with a weird amount of knowledge about how types and ABIs in Rust work, and I wanted to write it all down in one place so that… it’s written down in one place. Much of this information can or should be found in the Rust Language Reference and the Rustonomicon .

How Swift Achieved Dynamic Linking Where Rust Couldn't
For those who don’t follow Swift’s development, ABI stability has been one of its most ambitious projects and possibly it’s defining feature, and it finally shipped in Swift 5 . The result is something I find endlessly fascinating, because I think Swift has pushed the notion of ABI stability farther than any language…

Security assessment techniques for Go projects
The Trail of Bits Assurance practice has received an influx of Go projects, following the success of our Kubernetes assessment this summer. As a result, we’ve been adapting for Go projects some of the security assessment techniques and tactics we’ve used with other compiled languages. We started by understanding the…

Parse, Don’t Validate
Historically, I’ve struggled to find a concise, simple way to explain what it means to practice type-driven design. Too often, when someone asks me “How did you come up with this approach?” I find I can’t give them a satisfying answer. I know it didn’t just come to me in a vision—I have an iterative design process…

Comparing Parallel Rust and C++
In this tutorial, we will implement a Rust program that attempts to utilize 100% of the theoretical capacity of three relatively modern, mid-range CPUs. We'll use an existing, highly efficient C++ implementation as a reference point to compare how our Rust program is doing. We start with a simple baseline solution of…
