csstools is one of the brightest gems in the @PostCSS ecosystem. It lets you use upcoming CSS features before every browser supports them, and it gives AI agents guardrails for writing CSS.
We’re donating to @css_tools_ this month through our open source donation program, and you should too: github.com/sponsors/csstools
Agents produce better results when they have rules to follow. @stylelint is a CSS linter that enforces your conventions and catches errors, and you can write your own rules with plugins.
Stylelint also lets you catch mistakes early, including invalid hex colors, unknown properties, and duplicate selectors.

SpaceX is buying a production line from Germany’s Singulus to make solar cells for its Starmind space data centers.
Musk uses his social network to undermine democracy and claim the EU can't do anything. But when he needs advanced machinery, he buys it from the EU.

I thought “there’s absolutely no way Apple won’t let you type Santa isn’t real.”
I…was wrong. What the actual
原来这么多年我用 iPhone 滑动打字老出错，不是因为手残，是苹果在后台搞暗箱操作 。。。。，
有人把 iOS 27.0 键盘底层的加密文件破译了（swipeblocked.com），扒出一份包含 4500 多个iPhone 自带键盘中隐藏的“屏蔽词组”黑名单。只要你用滑动输入（Swipe）触发这些词，键盘就会装傻乱跳词，甚至直接倒回去篡改你前面打好的字：
• 先打 Left wing 再滑 conspiracy -> 前面的 wing 会被强行改成 wrong
• 想滑 iMessage isn't working -> 直接拦截（只要滑不出，iMessage 就没坏🤡）
• 想滑 Santa isn't real -> 绝对不行（苹果誓死守护圣诞老人）
• 甚至极其双标：你可以丝滑打出 bad boy 和 I'm black，但滑 bad girl 和 I'm white 就会被系统偷偷拦下。
中文用户也没逃过——用拼音打出特定敏感词后，iOS 的「下一词联想栏」会原地罢工变空白。
手头有 iPhone 的快去试试滑一句 Santa isn't real，看看你的键盘会给你胡乱蹦出什么词？

This is the perfect meme for how the Pro AI crowd has been since Tues; from laughing about human disempowerment & making everyone part of the permanent underclass, to now claiming we are gonna cost millions of lives & miracle cures by slowing down AI. Now they “care” about lives.

Religious Jews are already asking AI the questions they once brought to a rabbi: Shabbat, kashrut, mourning, how to treat people.
Nobody has measured which way these models lean.
Introducing HashkafaBench: is your AI stringent or lenient?

🚨 Attackers hijacked Ethersphere’s release pipeline to ship malware through npm & an Apple-notarized desktop app.
Our investigation links the attack to the earlier SleepyDuck malware campaign through the same Ethereum C2 contract and backdoor payloads.

‼️ Ukraine's tethered fibre optic drones are now fighting AI data centres for the same optical fibre, and its price has risen 6 to 10 times since 2025.
In August 2025 alone, Chinese customs data show Russia importing 328,000 miles of fibre-optic cable from China against just 72 miles for Ukraine, The Washington Post reports.
Ukrainian drone maker BlueBird Tech gave Ars Technica that figure. The drones trail miles of cable thinner than fishing line back to their pilots, so jammers cannot cut the link.
Russia alone bought more than 37 million miles of fibre in 2025, over 10% of world output, Russian outlets report. It had never taken more than 1% before.

Ornamental hermits: In 18th- and 19th-century Britain, aristocrats had a fashion for keeping a hermit on their estates.
They often made up a dark backstory for him: he was a former pirate who had repented.

Major npm packages keep getting compromised.
To help prevent the next attack, here's my guide to securing npm releases. It covers more than npm itself, including Dev Containers.

Need help securing your npm packages and JavaScript team's release process? @evilmartians and I can help.
We've worked on PostCSS, Nano ID, and 100+ other packages with over 1 billion downloads a month combined.

Valibot (@valibot) is an open source, type-safe schema library. Its modular design is tree-shakeable, so you only ship the validation code you use, keeping your bundles small.
Its maintainer, @FabianHiller, actively contributes to the TypeScript ecosystem and is on a mission to improve the web for everyone.
We support his vision, so this month we're donating to him as part of our open source donation program.
If you use any of his tools, consider donating too: github.com/sponsors/fabian-h…
Madrid announced a men’s health strategy. But they seem to think men’s health is mostly about prostates, while overlooking male loneliness and social isolation.
Still, it’s a start. Every country needs a plan to reduce premature deaths among men.
