When gradient descent is a kernel method
Suppose that we sample a large number N N N of independent random functions f i : R → R f_i \colon \R \to \R f i : R → R from a certain distribution F \Fc F and propose to solve a regression problem by choosing a linear combination f ˉ = ∑ i λ i f i . \bar{f} = \sum_i \lambda_i f_i. f ˉ = i ∑ λ i f i . For…

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…

Writing a Faster Sorting Algorithm
These days it’s a pretty bold claim if you say that you invented a sorting algorithm that’s 30% faster than state of the art. Unfortunately I have to make a far bolder claim: I wrote a …

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…

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…
