Putting Some Zig In A Linux-Based 3D Printer

After a day of programming in Zig

Một lập trình viên Rust chia sẻ trải nghiệm sau một ngày lập trình bằng ngôn ngữ Zig, so sánh những điểm khác biệt và ưu nhược giữa hai ngôn ngữ.

Lập trình viên nên đọc bài này để so sánh và hiểu rõ cách Zig giải quyết các vấn đề thiết yếu của Rust như quản lý bộ nhớ, tính năng an toàn và hiệu suất, giúp họ lựa chọn công cụ phù hợp hơn cho dự án của mình.

Engineering High-Performance Parsers with Data-Oriented Design

Bài viết chia sẻ kinh nghiệm xây dựng Yuku, một parser hiệu suất cao, bằng cách sử dụng mảng phẳng (flat arrays) chứa các chỉ số u32 thay vì cây con trỏ. Quyết định này ảnh hưởng sâu rộng đến thiết kế bộ nhớ, cấp phát bộ nhớ, xử lý chuỗi, Unicode và tuần tự hóa.

Lập trình viên nên đọc bài này để tìm hiểu cách thiết kế hiệu suất cao cho các trình phân tích (parser) bằng cách áp dụng thiết kế hướng dữ liệu (data-oriented design) với cấu trúc AST đơn giản và hiệu quả, giúp tối ưu hóa bộ nhớ và tốc độ xử lý.

My Thoughts on the Bun Rust Rewrite

Andrew Kelley, creator of the Zig programming language, shares his perspective on Bun's rewrite from Zig to Rust. He recounts the history of Bun's relationship with the Zig Software Foundation, criticizing Bun's poor code quality, management culture, and engineering practices. He expresses relief at the Rust rewrite and Anthropic's acquisition, as it severs a relationship he viewed as a net liability for Zig. He also rebuts several claims in Bun's official blog post, including assertions about fuzzing, LTO performance gains, and binary size improvements, arguing these were engineering failures unrelated to the language switch.

ghostel.el - Terminal emulator powered by libghostty

Ghostel is a new Emacs terminal emulator package that uses libghostty-vt (the VT engine from the Ghostty terminal) as its core. A native dynamic module written in Zig handles terminal state, rendering, and PTY I/O, while Elisp manages keymaps, buffers, and commands. It supports modern terminal protocols including the Kitty keyboard and graphics protocols, OSC 8 hyperlinks, OSC 4/10/11 color queries, synchronized output (DEC 2026), and inline images. Key features include five input modes (semi-char, char, emacs, copy, line), automatic shell integration for bash/zsh/fish/nushell, TRAMP remote terminal support, password prompt detection, calling Elisp from shell scripts, and cross-platform support including Windows. Pre-built binaries are auto-downloaded on first use; no Zig toolchain required for typical installation. It is compared favorably to vterm and eat.el, offering modern protocol support that libvterm lacks.

Interview With Mitchell Hashimoto

Mitchell Hashimoto, founder of HashiCorp and creator of Ghostty, shares his thoughts on terminal emulator design, Zig, open source philosophy, and software craftsmanship. He explains why he built Ghostty (to learn GPU programming, systems programming, and Zig), his vision for improving terminal protocols (n-screen API, button protocol), and his philosophy on open source maintainership — arguing users have no entitlement to demand changes from unpaid maintainers. He discusses Zig's evolution positively, his pragmatic use of AI for prototyping, and the importance of understanding computers at a low level rather than just learning languages.

Devlog

Zine is a fast, scalable, and flexible static site generator built with Zig. This devlog covers the full changelog from early versions through v0.12.0, detailing new features, breaking changes, and upgrade guides. Key highlights include: v0.12.0 introduces Ziggy syntax changes (tagged unions replacing @foo literals, struct leading dots), in-editor schema intelligence via Ziggy LSP, directory support for static assets, custom config fields via $site.custom, and a Firefox dev server fix. Earlier releases introduced standalone Zine (no Zig build system required), SuperMD content format with .smd extension, a full asset system, SuperHTML scripting improvements, Windows support, and numerous bugfixes. Each release includes migration instructions for upgrading config files and frontmatter syntax.

Unboxed: Zig

A detailed analysis of Zig's built-in package manager covering its mechanics, categorization, governance model, and threat model. Zig uses a build.zig.zon manifest with content-hash-pinned dependencies and no central registry — packages are fetched directly from URLs (primarily GitHub). Key design choices include treating the content hash as the package identity (not the URL), a bespoke .zon data format separate from the Turing-complete build.zig build script, and a self-generated fingerprint for stable package identity across URL changes. The analysis highlights strengths (zero external dependencies in the compiler itself, pure-data manifest readable without execution, hash-locked installs) and weaknesses (no transitive dependency override mechanism in the manifest, build.zig fails the 'Tuesday test' due to arbitrary code execution at build time, governance effectively delegated to GitHub, no checksum transparency log, bespoke format requiring custom parsers for cross-ecosystem tooling).
