Glad to see Yuku’s work shaping the next generation of JavaScript tooling. Congrats to the SWC and Rstack teams!
Introducing SWC Next: the foundation for SWC’s next major version, built on a new architecture inspired by Yuku. - Up to 3x faster native parsing - Up to 10x faster parsing through the JavaScript API - A flat, ESTree-based AST designed for speed, memory efficiency, and JavaScript extensibility Starting with parsing, we’re bringing the rest of SWC to this new architecture. Built together by the SWC and Rstack teams.

This React Compiler PR would help unblock downstream tools. Thanks to everyone who's reviewed it and helped bring it to the React team's attention! If anyone on the team has a chance to take a look, I'd really appreciate your feedback. Link in the first reply.

很喜欢这种模式. 或者说外部贡献本应如此.
Replying to @xuanwo
稍微解释一下漩涡独裁模式: 所有的 Issues / PRs 一经创建视为已经完成对辞达的贡献,我可以不经讨论对其做任意修改,我会保留作者原始的 credits,但是可能不保留任何代码

Applied to Codex for OSS! Over the past year, Codex has helped us fix bugs, resolve long-standing issues, and deliver major performance improvements in SWC. Excited to keep pushing SWC forward with Codex!
We started Codex for OSS six months ago. Today, we’re renewing the program with $100 Pro plans and doubling the number of grants (from 5,000 to 10,000) to reach more maintainers. (If you received a grant previously, we encourage you to re-apply!) openai.com/form/codex-for-os…

It seems like Sucrase hasn’t seen much development lately. I wonder what happened.

原子组合, 遵循 unix 哲学, 有极好的正交性和复用性. 但组合不是免费的, 在上下文切换边界有着性能损耗. 巨大单体, 就像 systemd, 强耦合极致性能. 但是难以拆出来单独使用其组件. 鱼和熊掌, 怎样才能都要?

有些 PR,实际上是在往项目里硬塞一段逻辑,直接扭转原有设计,只为了拟合某个提交者自己撞上的业务场景。 它不关心系统整体一致性,也不关心抽象边界,只会留下一句:“默认关闭,不影响兼容性。” 最后,项目不再有统一逻辑,只剩下一堆互相踩踏的开关。代码演化成没人敢动、没人能懂的混沌体。

假想存在一种软件开发方式: AI 先跑通 MVP,把接口文档定下来。 人类对照着进行净室开发。

Would it be secure if we do it this way?
Do you know that using GitHub CLI (gh) may expose you to supply-chain attacks? It stores a long-lived GitHub token on your machine, which can be stolen by any malicious scripts. This is what happened in the recent Nx Console supply-chain compromise, which led to GitHub’s internal source code being leaked.

每一次新需求, 需要背负一些技术债的时候, 项目质量就会向失控滑动. 而每一次重构, 都是人们尝试把现状往回拽, 尝试对抗熵增. 好消息是: 现在有了 AI, 可控的范围大幅增大了. 坏消息是: 有人发现 AI 进入后, 向右滑动更快了.

我所感兴趣的那些议题, 如编辑器体验包括代码补全错误提示代码高亮等, 还有构建体验如编译速度模块化, 甚至包括语言本身的语法设计框架的API设计等等, 这些议题都假设了一个前提, 人类编码, 人类阅读, 人类构建. 如果人类不在其中了, 该怎么办? 会发生这样的事吗?
