This is my vision for fixing that: a Nix-style content-addressed store, rebuilt at module granularity, beside the bundler instead of around it. 2026-09-28T00:00:00+00:00 https://rapha.land/staying-sharp/ https://rapha.land/staying-sharp/ Friends, coworkers and folks from the tech community keep asking me about if I still write code, so wrote down this article to put my thoughts somewhere. 2026-09-22T00:00:00+00:00 https://rapha.land/introducing-oj/ https://rapha.land/introducing-oj/ oj is a from-scratch, npm-free dev server and bundler written in Rust. It reads your existing vite.config, runs your existing Vite plugins, and reimplements React and TanStack Start natively, so you point it at a real app and it just runs. 2026-08-24T00:00:00+00:00 https://rapha.land/rio-terminal-multiplexer-rmx/ https://rapha.land/rio-terminal-multiplexer-rmx/ A protocol that lets an application open real terminal buffers over one connection, so the terminal renders panes natively instead of a multiplexer parsing every byte twice and dropping whatever it cannot model. 2026-08-18T00:00:00+00:00 https://rapha.land/closing-canario-terminal-source-code/ https://rapha.land/closing-canario-terminal-source-code/ Why Canario terminal is closed source: time, maintainer burnout, and building something just for myself. 2026-08-11T00:00:00+00:00 https://rapha.land/jamlog-001/ https://rapha.land/jamlog-001/ The first jamlog of Jam Programming Language, right after building a PlayStation emulator. 2026-06-04T00:00:00+00:00 https://rapha.land/no-ai-is-not-making-software-worse-people-are/ https://rapha.land/no-ai-is-not-making-software-worse-people-are/ AI is just a tool. The problem is much deeper, and it started long before AI ever entered the picture. We have been accepting bad quality software for years. 2026-05-23T00:00:00+00:00 https://rapha.land/adding-color-glyphs-to-glyph-terminal-protocol/ https://rapha.land/adding-color-glyphs-to-glyph-terminal-protocol/ Glyph Protocol shipped with a single payload format: monochrome OpenType `glyf` outlines rendered in the current foreground colour. This post covers adding two more: `colrv0` for layered flat-colour icons, and `colrv1` for full paint graphs with gradients, both by reusing OpenType COLR directly as the wire format. 2026-04-20T00:00:00+00:00 https://rapha.land/introducing-glyph-protocol-for-terminals/ https://rapha.land/introducing-glyph-protocol-for-terminals/ A protocol for terminals that allows applications to register custom vector glyphs and query whether a codepoint is renderable on the system — so you no longer need to install a 10MB font just to render a single icon. 2026-04-17T00:00:00+00:00 https://rapha.land/the-art-of-craftsmanship-monozukuri-in-the-age-of-ai/ https://rapha.land/the-art-of-craftsmanship-monozukuri-in-the-age-of-ai/ AI usage has been increasing over the past few years due to its biggest selling point: time. It is often marketed as a tool that helps developers reduce the overall time needed to perform a task. 2026-01-14T00:00:00+00:00 https://rapha.land/craft-software-that-makes-people-feel-something/ https://rapha.land/craft-software-that-makes-people-feel-something/ Recently, people have been asking me why I’m pausing Boo to work on a programming language. I think it would actually be cool to write down how I feel. 2025-12-11T00:00:00+00:00 https://rapha.land/building-boo-code-editor-1/ https://rapha.land/building-boo-code-editor-1/ I decided to document Boo code editor development for good (or bad). Suppose you have any interest in it. Please stick with me in this article. 2025-03-31T00:00:00+00:00 https://rapha.land/joining-charm/ https://rapha.land/joining-charm/ Two years ago, to be precise Oct 2022, I started Rio Terminal because I wanted to learn Rust and wanted to have a project that I would use in my daily life. I always loved terminals and thought well why not? Truth is that, was such a good investment of my time, not only did I learn Rust but I also... 2024-12-16T00:00:00+00:00 https://rapha.land/why-am-i-creating-a-new-code-editor/ https://rapha.land/why-am-i-creating-a-new-code-editor/ 2024-11-13T00:00:00+00:00
