I'm very excited that my blog uses gatsbyjs and PWA

汇集一下 DESIGN.md 工具网站：

1. https://t.co/A1npO67bbz
2. https://t.co/ywX2NAcmsr
3. https://t.co/gY76y0ZxWo
4. https://t.co/PQ1ueFHiYV
5. https://t.co/dF0RWlLkcf
6. https://t.co/oyDlXoV4g7

个人推荐 refero，提供了 2,000+ DESIGN.md，以及支持 DESIGN.md、Tailwind v4、 CSS Variables 和 Design Tokens 最全面的配置输出。

neuform 给我的视觉体验更好，除了 getdesign md，其他全都支持输入任意网站生成设计规范和配置，design-md-chrome 则是 chrome 的扩展适合即开即用。

Anthropic 发了份 32 页的 Claude Skills 构建指南，把技能开发从规划到分发整个生命周期讲透了。

最值得看的是五种核心设计模式和触发可靠性测试方法——与其每次重复写 prompt，不如把常用工作流封装成 Skill，一劳永逸。

https://t.co/Tf6y5QRtxp 这网站很有想法啊，原型图用 ASCII 来画，确实有天然优势，直接 copy markdown 给大模型用，比用其他图片或者文字描述啥的方便多了。做的也很精致，还能用AI 生成线框图，很实用有趣的想法，收藏了。

If you run Node.js in production, this will resonate:
👉🏼 https://t.co/ko3t9uhdSj

🔹 CPU spike.
🔹 You generate a profile.
🔹 Thousands of frames.
🔹 Deep V8 stacks.
🔹 High self-time hotspots.

You know something is slow.
But what do you change?
And how do you prove it’s better?

This breakdown shows how N|Sentinel:
• Identifies the true bottleneck
• Retrieves contextual source code
• Generates an optimized version
• Benchmarks it automatically
• Validates measurable improvement

Not just observability.
Intelligent remediation.

For serious Node.js production teams, this changes the workflow.

We cut @nodejs memory in half with a one-line Docker image swap.

No code changes. No new APIs. Just smaller heaps.

Here's what happened when we tested pointer compression on real workloads 🧵

Google launched a brand new AI tool.

It's called CodeWiki, and it might be the biggest upgrade GitHub has had in years.

And all you do is paste your GitHub repo in, and it turns your entire project into an interactive guide.

It also generates diagrams, explanations, walkthroughs, everything you could ever want, and even a chatbot that knows the code better than anyone else.

So you never have to dig through a giant repo again wondering what does this do

September, 26: Cloudflare rewritten in “memory safe” Rust.

The change is touted as “faster and more secure” because of Rust.

https://t.co/JqtUziMGpU

November, 18 (53 days later): Cloudflare has a massive outage, which took down large portions of the Internet, because of a memory error… in that Rust code.

New in @ChromeDevTools! Debug an app's full performance trace with Gemini!

After recording a trace, you can now chat with Gemini about the entire trace, related Performance insights, and even connected field data - all without needing to select specific context beforehand!

🦀 Struggling with Pin / Unpin in Async Rust?

If “don’t move the future”, self-referential structs and pinning rules all feel complex, this deep-dive will finally make it click:

We forked Chromium and bolted on a lock-free, zero-copy, low-latency shared memory ringbuffer written in Rust

We needed to IPC 100+ MB/s of raw video, and Chromium's WebSocket implementation is dreadfully inefficient

Introducing https://t.co/ZWLhp5tXA7

I often check raw logs - out/error.log, nginx's access.log, etc, but they're hard to read

Inspired by @levelsio 's https://t.co/1nHhguKzFi I built beautiful parser & formatter with search and syntax highlighting, data never leaves the browser

[Matteo Collina @matteocollina]

Get started now:

npm i @platformatic/watt-admin -g
watt-admin --record --profile cpu

Happy profiling 🔥

🚨 WARNING: A “Featured” Chrome extension was silently copying everything users typed into ChatGPT and other AI tools.

Prompts. Responses. Sent off-device by default after an auto-update.

It even warned users about sharing sensitive info, while exporting the full chats itself.
