Some Thoughts on Zig
One of the biggest things Zig has going for it—especially compared to Rust—is that it is (relatively) small. That sits in tension with Rust’s approach to solving memory safety problems, and sets up a nice challenge for future programming language designers.

Buffers on the Edge: Python and Rust
One of my least favorite kinds of bug is when two different systems are interacting and the result has bad behavior but it’s difficult to say which (if either!) system is at fault. This is one of those stories, about Python’s buffer protocol and Rust’s memory model.

Our Experience Porting the YJIT Ruby Compiler to Rust
In this post, I want to give a nuanced perspective on our experience porting YJIT from C to Rust. I'll talk about the positives, but also discuss the things that we found challenging or suboptimal in our experience.

The Awk state machine parser pattern (2018)
I run the Ganglia Monitoring System on the home lan to keep an eye on temperatures, loads, disk usages, network throughput and such on the gateway and, more recently, my desktop workstation as well 1 1 The primary reason is that I have noticed some instability, and I would like to know if it’s related to temperature…

Why “process substitution” is a late feature in Unix shells
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

Parsing JSON faster with Intel AVX-512
Many recent Intel processors benefit from a new family of instructions called AVX-512. These instructions operate over wide registers (up to 512 bits) and follow the Single instruction, multiple data (SIMD) paradigm. These new AVX-512 instructions allow you to break some speed records, such as decoding base64 data at…

Avoid exception throwing in performance-sensitive code
There are various ways in software to handle error conditions. In C or Go, one returns error code. Other programming languages like C++ or Java prefer to throw exceptions. One benefit of using exceptions is that it keeps your code mostly clean since the error-handling code is often separate. It is debatable whether…
