It supports multiple search modes, including regex with capture groups. https://beeb.li/blog/introducing-swpui Fri, 15 May 2026 22:19:00 GMT rustsearchratatuitoolingannouncement https://beeb.li/blog/fish-shell-tips-and-tricks A collection of tips and tricks for the fish shell I wish I had known about a long time ago. https://beeb.li/blog/fish-shell-tips-and-tricks Sun, 04 Jan 2026 21:34:00 GMT fishshelllinuxtutorialtips https://beeb.li/blog/optimizing-text-offset-calculation A tale of optimization for an algorithm that turns byte offsets into line and column numbers, and UTF-16 offsets. The final implementation leverages SIMD and fixes several inefficiencies in the original solution. https://beeb.li/blog/optimizing-text-offset-calculation Sat, 18 Oct 2025 19:46:00 GMT rustsimdoptimization https://beeb.li/blog/announcing-lintspec Lintspec is a command-line utility (linter) that checks the completeness and validity of NatSpec doc-comments in Solidity code. It is focused on speed and ergonomics and aims to improve the user experience over existing solutions. https://beeb.li/blog/announcing-lintspec Wed, 26 Feb 2025 21:00:00 GMT rustsoliditytoolingannouncement https://beeb.li/blog/aws-lambda-rust-docker In this short article, we go over a setup to distribute AWS Lambda endpoints written in the Rust programming language through Docker images instead of a zipped binary. This technique leverages the power of Cargo Lambda and multi-stage Docker builds. https://beeb.li/blog/aws-lambda-rust-docker Fri, 22 Nov 2024 12:27:00 GMT rustdockeraws lambdawebdevtutorial https://beeb.li/blog/calendar-component-svelte-tailwind Let's create a localized monthly calendar component together, using Svelte and TailwindCSS with minimal dependencies. To achieve this result, we explore the internationalization APIs of JavaScript and use some clever maths to generate a simple markup. After detailing each piece of the puzzle, we put everything together into a simple but customizable demo which can serve as the basis for your calendar needs. https://beeb.li/blog/calendar-component-svelte-tailwind Thu, 01 Aug 2024 15:36:00 GMT sveltetailwindjavascriptwebdevtutorial https://beeb.li/blog/diff-testing-solidity-rust-foundry Differential testing allows to compare implementations and is especially useful in Solidity, where optimizations are frequently made by replacing code with low-level YUL instructions. By leveraging the fast startup times and low footprint of Rust binaries via FFI, Foundry allows to efficiently integrate diff testing in Solidity projects. https://beeb.li/blog/diff-testing-solidity-rust-foundry Sun, 16 Jun 2024 15:52:00 GMT rustsolidityfoundrytestingtutorial
