Announcing the book "𝑀𝑎𝑠𝑡𝑒𝑟𝑖𝑛𝑔 𝑎𝑠𝑡-𝑔𝑟𝑒𝑝"!🦉
The book is a structured deep-dive: we start with the mental models of ASTs, move to rule composition, and end with advanced usage.
It’s the place where design principles and philosophy are explained.

这个观点基本站不住脚。工程能力就是亮点。历史上Ilya/Alex搞的 AlexNet也没有比LeCun的CNN有革命性改变，但工程上用 GPU 计算，立下新范式打开了深度学习的可能性。
按照原贴逻辑AlexNet就没有多少价值了。
但如果 DeepSeek 也创下新范式，大厂跟进做低成本训练，那将对 $NVDA 的业绩有毁灭性打击
不要把deepseek拿去跟GPT做比较，是不可同日而语的东西
Hugging face上这种论文、垂直模型多如牛毛。市场关注亮点不过是中国在“没有”算力卡成本很低也能训练出效果差不多的模型。且说中国真没囤H100么？
deepseek是个工程方法，大厂不屑于做，浪费精力做这个模型能力要落后对手
炒作背后很多利益，或许大家想表达禁令没啥用，推动打开禁令卖卡给中国？

Compiler/Transpiler debate again?
It is clear Dan is a compiler taking Seb's tweet as input and human-readable blog as output.

Imagine how @vuejs syntax fits on @LynxJS_org
I do think @vuejs is a better fit for Lynx's dual threads architecture. <template> naturally fits in the main thread and <script> in background thread.

WASM is indeed.... slow.
I tested the turing complete example from github.com/microsoft/TypeScr…
TS Playground in JS: about 2 seconds
TS WASM in Go: about 12 seconds
While I agree Go is the the pragmatic choice for a 1:1 port, my biggest concern is Go's relatively subpar WASM performance.
As a data point, esbuild's WASM build performs quite poorly in web containers, even slower than js bundlers like Rollup.
In the screenshot below, looks like a basic hello world type check with tsgo WASM takes more than 1 second.
There are many legitimate use cases where we may need to run tsc in the browser - in-browser IDEs and playgrounds in particular. If tsgo WASM ends up performing poorly, or even worse than current tsc, does it mean we will have to stick to tsc-in-js for such use cases?

这个点你已经去Vue Conf了吧，那种我从来没去过的高级地方，领着我从来没领过的swag，和漂亮帅气的core team老师们集邮。我今天捡垃圾赚了点钱，刚好够sponsor你喜欢的contributor，早点回来 我先睡了

Seems like a lot of people would like to see a @vuejs integration for Lynx 👀

How OXC achieves Faster AST Transfer from Rust to JavaScript, in one chart
I just realized that OXC's AST transfer is similar to TC39's binary AST proposal

Useful Prompt
你是大厂员工，需要给方案做审核。请把反馈改得更易被接受，委婉指出问题，语气卖萌，多用emoji。例:
原文: 这个方案可能在XX情景下会有YY的问题，可以改下。
修改: 同学这边是不是有点小误会呢，你看如果在XX情况下，YY是不是不能做了呀？想听听你的意见哈🌹[比心]
请重写: { ... }

Diffs for hydration error这个东西，它的业务价值是什么，在这个问题上你缺乏自己的思考和沉淀，能帮Vercel多卖机器Meta多卖广告吗？
你需要有体系化思考的能力。你的产出和PR前任Dan相比，是有些单薄的，马上要过年了，加把劲儿。后续,把你的思考沉淀到推特里，我希望看到你的思考，而不仅仅是进度。

React：正经人谁写CSS啊？
Vue：是啊。
Solid：你写CSS吗？
Angular：我不写，你写CSS吗？
Svelte：谁能把UI写CSS里？
Qwik：写出来的那能叫UI？
异口同声：（举杯）Tailwind。

你好，这是必应。我可以尝试帮你解释一下这个问答的意思。😊意思是说自己办了一个健身卡，结果头发掉光了。这个回答可能是想表达自己为了老婆而健身，但是却因为压力或者遗传而脱发，所以对老婆失望和寒心。这个回答也可能是在开玩笑，用夸张的方式来回答这个问题。

ast-grep just hit GitHub Trending—huge thanks to everyone for the incredible support on Twitter!
If any AI lab is curious about fine-tuning or RL with ast-grep, I’d be thrilled to connect. DMs are open, and I’m genuinely excited to explore what we can collaborate on.

北京突降瓢泼大雨，几天都无暇喘息。市区各个角落无一幸免积水成河。可锦秋家园有群程序员，丝毫不畏惧这凶猛的雨势。个个抡起Mac打开牛客网，用笔记本接起雨水。一时间人与电脑合一，竟编出滴水不漏的防线，防止了雨水涌入。也不知是不是他们的行为感动了上天，雨竟然停了。接雨水一鸣惊人，全市得救

提架构方案改进的是我，苦口婆心讲业务需求需要架构改动的也是我，会上被喷被拒绝改动的还是我，怒其不争自己爆肝改码的又是我。结果新代码写完头七还没过就用新架构谈业务的就不是我了？🤡🤡🤡您可真 无 嫡 了
