The borrow checker within
This post lays out a 4-part roadmap for the borrow checker that I call “the borrow checker within”. These changes are meant to help Rust become a better version of itself, enabling patterns of code which feel like they fit within Rust’s spirit , but run afoul of the letter of its law . I feel fairly comfortable with…

Writing a RISC-V OS in Rust: System Calls
System calls are a way for unprivileged, user applications to request services from the kernel. In the RISC-V architecture, we invoke the call using the ecall instruction. This will cause the CPU to halt what it's doing, elevate privilege modes, and then jump to whatever function handler is stored in the mtvec…

Some Reasons to Measure
A question I get asked with some frequency is: why bother measuring X, why not build something instead? More bluntly, in a recent conversation with a newsletter author, his comment on some future measurement projects I wanted to do (in the same vein as other projects like keyboard vs. mouse , keyboard , terminal and…

Deep Tracing of Internet Explorer
After reading a recent post by Steve Souders concerning a free tool called dynaTrace Ajax , I was intrigued. It claimed to provide full tracing analysis of Internet Explorer 6-8 (including JavaScript, rendering, and network traffic). Giving it a try I was very impressed. I tested against a few web sites but got the…

Controversial programming opinions
One of the very first ideas we had for this blog was to convert some of the wonderful gems of the early era of our site, the undisciplined period, to blog posts. Questions that were once enthusiastically received by the community, but no longer fit Programmer’s scope.

How many floating-point numbers are in the interval [0,1]?
Most commodity processors support single-precision IEEE 754 floating-point numbers. Though they are ubiquitous, they are often misunderstood. One of my readers left a comment suggesting that picking an integer in [0,232) at random and dividing it by 232, was equivalent to picking a number at random in [0,1). I am not…
