Building made me switch from Claude Code to Codex. Claude’s token usage was too expensive for my workflow. GPT-5.6 Sol + Codex lets me focus on building instead of watching usage limits. Loving it so far! 🚀 @OpenAI @thsottiaux

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！

一起来背单词吧！ 平时看文献、写论文都离不开英语，词汇量一直是个绕不过去的坎。市面上背单词的 App 不少，扇贝、百词斩、墨墨之类的我也都用过，但是总有些地方不太舒服，得登录、有广告、打卡提醒烦人，还老是惦记着你的数据。作为一个喜欢自己重复造轮子的让，我写了一个背单词的网站，自己需要什么功能就写什么功能。 纯静态网站，部署在 GitHub Pages 上，数据全部存在你自己的浏览器里，这可能也是我最喜欢的服务部署方式了哈哈哈。地址：[jiaoyuan.org/recite]( https://jiaoyuan.org/recite/)，源码在 [GitHub]( https://github.com/imjiaoyuan/recite)。 ## 一次完整的背诵流程 打开首页，是一排词表卡片，每个词表一张。卡片上写着总词数、今天到期要复习的词有多少、还能新背几个，下面一条进度条显示你背到哪了。想背哪个点进去就行。 每张卡片先是正面：英文单词、音标、词性，点一下单词或小喇叭可以发音。你在脑子里想过意思之后，按空格（或点按钮）翻开，背面是中文翻译、英文释义和一条例句。
