Ask HN: What did you read in 2025?
Getting into reading again this year after a long break. The most memorable read of this year was “The Count of Monte Cristo” (1846) by Alexander Dumas . It’s one of the greatest stories ever told. It’s ~1250 pages but I sped through it in 3 weeks even if I’m a slow reader. Highly recommended! […]
Package managers keep using Git as a database, it never works out
Using git as a database is a seductive idea. You get version history for free. Pull requests give you a review workflow. It’s distributed by design. GitHub will host it for free. Everyone already knows how to use it. Package managers keep falling for this. And it keeps not working out. Cargo The crates.io index […]
I’m a laptop weirdo and that’s why I like my new Framework 13
This month I sold my 2021 M1 Max Macbook Pro and bought a Framework 13 DIY Edition laptop. After I got everything setup I sat down to write about the experience. Some ~4500 words later I realized I needed to break my thoughts into multiple posts. See also: My new Framework 13 laptop just arrived. […]
Codex vs. Claude Code (today)
Dec 22, 2025 | 5 min read Every programmer has their favorite language. Some prefer Python, while others swear by TypeScript1. Many teams build their apps on Postgres, while others use MySQL. These choices are often flame-war bait for programmers with strong opinions, but most of these decisions are centered around pragmatism, priorities, and tradeoffs. […]

Building an AI agent inside a 7-year-old Rails monolith
I’m a Director of Engineering at Mon Ami, a US-based start-up building a SaaS solution for Aging and Disability Case Workers. We built a large Ruby on Rails monolith over the last 7 years. It’s a multi-tenant solution where data sensitivity is crucial. We have multiple layers of access checks, but to simplify the story, […]
TurboDiffusion: 100–200× Acceleration for Video Diffusion Models
This repository provides the official implementation of TurboDiffusion, a video generation acceleration framework that can speed up end-to-end diffusion generation by $100 sim 200times$ on a single RTX 5090, while maintaining video quality.TurboDiffusion primarily uses SageAttention, SLA (Sparse-Linear Attention) for attention acceleration, and rCM for timestep distillation. Paper: TurboDiffusion: Accelerating Video Diffusion Models by 100-200 […]

Ultimate-Linux: Userspace for Linux in Pure JavaScript
This is a fun tiny project for building a tiny Linux distribution in just JavaScript (and a tiny bit of C to enable mounting to get some fun results). — ULTIMATE LINUX SHELL — Commands: ls, cd, cat, mkdir, mount, exit Background context I post a lot on X (Twitter) and if you don’t follow […]
MiniMax M2.1: Built for Real-World Complex Tasks, Multi-Language Programming
MiniMax一直在用更AI 原生的方式改造自己。这个过程的核心驱动力是模型、Agent脚手架和组织。在探索过程中，我们对上述三点也有了越来越深刻的认知。今天我们开放模型部分的更新，也就是MiniMax M2.1，希望有机会能帮助到更多的企业和个人早日找到更AI原生的工作（生活）方式。 在10月底的M2中，我们主要解决模型成本和模型开放性的问题。在M2.1中，我们致力于提升真实世界复杂任务中的表现：重点聚焦于更多编程语言和办公场景的可用性，并在这个领域做到最好的水平。 MiniMax M2.1 具体模型亮点如下: 卓越多编程语言能力 过去很多模型主要围绕 Python 优化, 但真实世界的系统往往是多语言协作的结果。 在 M2.1 中, 我们系统性提升了 Rust / Java / Golang / C++ / Kotlin / Objective-C / TypeScript / JavaScript 等语言的能力, 多语言任务整体表现达到业内领先水平, 覆盖从底层系统到应用层开发的完整链路。 WebDev 与 AppDev：能力与美学的整体跃迁 针对业界普遍存在的移动端开发短板, M2.1 显著加强了原生 Android / iOS 开发能力。 同时, 我们系统性提升了模型在 Web 与 App 场景中的设计理解与美学表达能力, 能够出色地构建复杂交互、3D科学场景模拟与高质量可视化表达, 推动 vibe coding 成为可持续、可交付的生产实践。 […]
