Today, I’d like to introduce you to PhipsBoot. 🎉 I started working on it in September 2023 or so, but polished it just recently. A lot of knowledge from my previous blog post about x86 Kernel Development & Relocatable Binaries went into this project. PhipsBoot is a relocatable x86_64 bootloader Read more…
In early 2021 I had a closer look into several aspects of digital signal processing (DSP), including lowpass filters, frequency spectrum analysis, and audio visualization. I used Rust to experiment with this. The Rust ecosystem didn’t offer simple-to-use libraries for my use cases back then, or at least they were Read more…
What I show in this blog post is nothing new or unique, but it is something I wish someone would have shown me in this simplicity in my second or third semester at university. In this post, I briefly explain how you can talk to Linux without the libc or Read more…
The other day I had some fun with assembly and wanted to try to call assembly functions from Rust. Each compiler follows a certain calling convention, that specifies how parameters are passed between functions. The calling convention is part of an ABI, an application binary interface. There are two major Read more…
Update: Since Rust 1.59, the macros global_asm! and asm! are finally stable! I also updated the blog post a little but it is mostly in the state from back then. In this blog post, I show how you can create assembly files next to Rust files and compile everything by Read more…
Update: In the meantime, my knowledge of Rust got better. &str simply uses the layout of a fat pointer. Original article down below. TL;DR: At least on x86_64 a &str is two u64 (16 byte) long. The first u64 is a pointer and the second u64 is the length of Read more…
