Half of them only make sense in specific projects. The other half clash with each other depending on what I'm working on. And all of them live in my dotfiles, loaded into every shell session whether I need them or not. Wed, 11 Mar 2026 Unknown https://d34dl0ck.me/accept-text-markdown/index.html https://d34dl0ck.me/accept-text-markdown/index.html Every website you visit today sends you a pile of HTML, CSS, and JavaScript — even if all you wanted was to read a blog post. Your browser downloads layout grids, tracking scripts, cookie banners, and font files before you see a single paragraph of text. For a 2000-word article, the actual content might be 12 KB. Everything around it: 2 MB. Mon, 09 Mar 2026 Unknown https://d34dl0ck.me/cargo-codesign/index.html https://d34dl0ck.me/cargo-codesign/index.html You built a Rust GUI app. It compiles. It runs on your machine. You send the binary to a friend, they double-click it, and macOS says: "Apple could not verify this app." Right-click, Open, confirm the scary dialog — it works. But that's not a shipping experience.

Sat, 31 May 2025 Unknown https://d34dl0ck.me/rust-bites-designing-error-types-in-rust-libraries/index.html https://d34dl0ck.me/rust-bites-designing-error-types-in-rust-libraries/index.html When designing error types in Rust, especially for libraries with a public API, there are several important considerations to keep in mind. This post will explore some of the important implications and common pitfalls when designing error types in Rust libraries. Further, we will look at thiserror and how the Rust standard library's std::io::Error can serve as a reference for designing your own error types.

Tue, 14 Jun 2022 Unknown https://d34dl0ck.me/rust-bites-as-ref/index.html https://d34dl0ck.me/rust-bites-as-ref/index.html the AsRef trait is everywhere in the std lib and very handy. However, the benefit using it is maybe not too obvious. But read on, and you will see some useful examples and where to apply it. Fri, 22 May 2020 Unknown https://d34dl0ck.me/rust-bites-macro-rules/index.html https://d34dl0ck.me/rust-bites-macro-rules/index.html Rust has a very strong and typed macro system.

Thu, 07 May 2020 Unknown https://d34dl0ck.me/ssd-benchmark/index.html https://d34dl0ck.me/ssd-benchmark/index.html Today I've discovered simple disk benchmark written in C and I wanted to give a very minimal version of it a try in rust. Let's explore the new crate and command line tool ssd-benchmark and discover how simple it actually is to benchmark a disk. Sun, 03 May 2020 Unknown https://d34dl0ck.me/rust-lifetime/index.html https://d34dl0ck.me/rust-lifetime/index.html Rust lifetimes have the reputation to be very complicated, hard to use and even harder to understand. With this little article the entry barrier should be lowered and clarity should shine among the curious reader. Thu, 05 Sep 2019 Unknown https://d34dl0ck.me/rust-hexdump/index.html https://d34dl0ck.me/rust-hexdump/index.html Rust is not an OOP language, but there are still ways to implement polymorphism and interfaces in rust. Here we going to explore how traits can be used to introduce interface semantics in Rust on a little hexdump tool.
