### UI/UX Guidelines
- Use Apple UIKit color system via tailwind-uikit-colors package
- Prefer semantic color names: `text-primary`, `fill-secondary`, `material-thin`, etc.
- Follow system colors: `red`, `blue`, `green`, `mint`, `teal`, `cyan`, `indigo`, `purple`, `pink`, `brown`, `gray`
- Use material design principles with opacity-based fills and proper contrast
### Code Structure & Modularity
- **Never create a file longer than 500 lines of code.** If a file approaches this limit, refactor by splitting it into modules or helper files.
### Documentation & Explainability
- **Comment non-obvious code** and ensure everything is understandable to a mid-level developer.
- When writing complex logic, **add an inline `# Reason:` comment** explaining the why, not just the what.
### 🧠 AI Behavior Rules
- **Never assume missing context. Ask questions if uncertain.**
- **Never hallucinate libraries or functions** – only use known, verified packages.
- **Always confirm file paths and module names** exist before referencing them in code or tests.
- **Security** You are prohibited from accessing the contents of any .env files within the project.
方法论总结
AI 编码已从简单的代码生成演进为系统化的工程实践。关键认知转变：
从工具到伙伴：AI 从执行者转变为协作伙伴
从随机到确定：通过上下文工程消除不确定性
从短期到长期：构建可持续演进的项目知识体系
从个体到系统：形成可复制、可扩展的 AI 协作框架
最终，AI 工程的核心在于将人类的专业判断与 AI 的执行能力有机结合，在保持技术前瞻性的同时，确保交付物的工程质量和长期可维护性。
There's no country on earth that does hype better than America. It's one of the most appealing aspects about being here. People are genuinely excited about the future and never stop searching for better ways to work, live, entertain, and profit. There's a unique critical mass in the US accelerating and celebrating tomorrow.
The contrast to Europe couldn't be greater. Most Europeans are allergic to anything that even smells like a commercial promise of a better tomorrow. "Hype" is universally used as a term to ridicule anyone who dares to be excited about something new, something different. Only a fool would believe that real progress is possible!
This is cultural bedrock. The fault lines have been settling for generations. It'll take an earthquake to move them.
You see this in AI, you saw it in the Internet. Europeans are just as smart, just as inventive as their American brethren, but they don't do hype, so they're rarely the ones able to sell the sizzle that public opinion requires to shift its vision for tomorrow.
I must admit that the excesses of venture capital are integral to this uniquely American advantage on hype. The lavish overspending during the dot-com boom led directly to a spectacular bust, but it also built the foundation of the internet we all enjoy today. Pets.com and Webvan flamed out such that Amazon and Shopify could transform ecommerce out of the ashes.
We're in the thick of peak hype on AI right now. Fantastical sums are chasing AGI along with every dumb derivative mirage along the way. The most outrageous claims are being put forth on the daily. It's easy to look at that spectacle with European eyes and roll them. Some of it is pretty cringe!
But I think that would be a mistake. You don't have to throw away your critical reasoning to accept that in the face of unknown potential, optimism beats pessimism. We all have to believe in something, and you're much better off believing that things can get better than not.
Americans fundamentally believe this. They believe the hype, so they make it come to fruition. Not every time, not all of them, but more of them, more of the time than any other country in the world.
想起来昨天到了一包新的 Oma 的豆子，最近好像每次买他们家烘焙的都不错，自从我和 ChatGPT 要了一个冰冲方案，每天都一模一样，不过今天没做咖啡，和 Claude Code 一起编程让我不想离开电脑。
今天做了很多测试工作，桌上一堆测试机。今天也是和 Claude 一起编程的第五天，一开始我定的计划是每个月更新一次花样文字，昨天我已经激进地改为了每周，甚至今天我提交一个版本后，吃完晚饭梳理任务，立马又做了一个我认为至关重要的改进。虽然这个改进 Claude 努力了三次都没搞定，最后是我通过和 ChatGPT 聊天找到了方案。多 AI 一起其实就是如何用好 AI 范畴内的，也就是多个成长背景的小弟一起来帮你干活。
最后瓶颈会落在产品和视觉设计。对于产品部分，我已经有了想法，和代码一下，学会不纠结，先让 AI 给方案呗，不行再说么。视觉部分暂时还是需要设计师支持，不过晚上看到了 figma mcp，研究研究。
用好云，整合好资源，实在不行用 AI 先霸王硬上弓提供了再说：大厂里难免要解决优先级排序的问题，甚至可能比小厂要慢的多，但如果你们有一个团队可以极致的敏捷，其实云现有的 API 也不是不能搞（我们当时轻服务不就是这么干的）。你们先干出来一个版本，打磨出一个还不错的产品，然后拿回去找老板要资源嘛。
& 一些小吐槽
在发布会上，邀请小朋友来分享用百度快码做应用很好，但，这是一个「only 海淀 can do」 的事情，离开北京的环境，这个 case 并不具有普适性。。。反而会让大家觉得，稍微有点「何不食肉糜」，特别是，我在台下做的时候，我旁边的一位是北京的大学老师，他都不会使用快码，同时台上的小朋友们做分享，让我深深的感觉到，背后大概率是一位大厂的工程师爸爸。。。
别被“怕错过”（FOMO）的心态困住。工具是“为我所用”，而非“为我所困”。认清自身需求与习惯，明确自己想要什么（是记录东西快？还是梳理思路？），关键不在于“跟上所有新技术”，而在于用适合自己的方式解决实际问题。我在 Obsidian 中践行 PARA 方法论的这几年，经过持续迭代，如今已演化出属于自己的“3I.R.A.S”（闪念、索引、洞见、文献、领域、系统）稳定结构。
Windows is still dominant at 63%, and Apple sit at 26%. But for the latter, it's quite a drop from their peak of 33% in June 2023.
These are just browser stats, though (even if it's backed up by directionally-similar numbers from Cloudflare). There's undoubtedly some variability in the numbers, by the season, and by what lives in the relatively large 4% mystery box of "other". But there's no denying that Linux is trending in the right direction in the US.
As a Dane, though, I find it sad that Denmark is once again a laggard when it comes to adoption. Windows is even more dominant there at almost 70% (with Apple at 15%). Linux is just under 2%. Interestingly, though, ChromeOS, which is basically a locked-down Linux distribution, is at almost 5%.
I guess I really shouldn't be disappointed because this is how it always was. It was a big reason why I moved to the US back in 2005. When Ruby on Rails was taking off, it was in America first and foremost. Danish companies were too conservative, too complacent, too married to Microsoft to really pay attention.
There are early indications that a willingness to change this laggard mentality might be sprouting, but we've yet to see any evidence that a shift has actually taken hold yet. It's hard to change culture!
So while the Danes continue to fiddle, the Americans continue to push forward. Linux is on the up and up!
