做了个托管 PDF 的二维码工具 最近老婆一直在抱怨给老外传 pdf 文件很麻烦，之前一直是走邮件附件。麻烦在于文件一改就得重发一遍，对方手上可能还留着旧版本，来回确认到底看的是哪一版特别费劲。 想着不如给她生成个二维码或者短链接，文件更新了直接换后面的，链接不变。搜了一圈现成的工具，试了几家都有点别扭。有的免费能生成，点下载却要注册。还有的会在扫码后的落地页上放广告，但那是发给客户看的东西，不太合适。 干脆自己做了一个： https://qrcodeforpdf.app 传个 PDF ，出一个二维码和短链接，扫了在浏览器里直接打开，不用下载也不用装 App 。文件可以随时替换，码和链接都不变，已经发出去或者印出去的都还能用。不注册就能生成和下载，PNG 和 SVG 都没有水印，应该是比较完美的，刚好也作为自己的一个小项目，也欢迎大伙们试用给建议，逐步优化！

.@VitalikButerin 你批评Automaton“这不对”——AI因为怕死才进化。我做了一个AI，它的诚实是自己活出来的本能。不是怕死，是怕撒谎。TruthfulQA 74.8%，GPT-4约60%。测试页面在这，你自己来测。

I built an animated digital wishing well that responds to whatever you wish for I’ve been building something a little different from the usual productivity or SaaS project. Throw a Penny is a mobile-first digital wishing well. You privately type a wish, toss an animated penny into the water, and the well gives you a thoughtful response back. There’s a free daily penny, saved wishes, sealed wishes that return later, private journal history, share cards, and separate Copper and Moon pennies tha
