I trained an LLM that runs on an ESP32 and directly in the browser Link to try it out yourself is: topk.sh The models download their weights directly in the browser so it works offline. Keep in mind they are very small and inaccurate. (8M and 13M parameters) However, I am building 500M and 1B+ parameter local models for agent based coding and other purposes. I will be shipping hardware designed for these tasks which connect directly to you computer or other device.

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！

Hey HN, I'm really excited to share Emra with you. The yc description would be: It's like "Notion meets Lovable". It's a workspace where you build full apps using AI and every app sits on one shared database and service layer. Generated apps are always editable, and (coming soon:) can interact with each other in the workspace. I'm of the opinion that the cost of software will go rapidly to zero (I don't think that's too surprising to any of you), but there will always be room for effort and creativity. Emra is essentially built for the future where every person is a developer. Essentially personal software for everyone. So far I've built notes apps with a 3d graph view to see connections, a video editing app and a canvas design tool (figma clone) with export capabilities, as well as a collection of project management tools and games. Right now the most satisfying thing is being able to fix a bug I run into in around the same amount of time that it takes to send a bug report in any tr

Claude 中国用户检测工具，封号风险预估 Claude Code 经常被封号，一般是 vpn 节点问题，本地环境现在 claude 也开始加了地域检测，时区、语言、系统字体这些信号都会被扫一遍，判定你是中国用户就给封号！ 做了一个本地工具，扫描本地数据检测，评估你的环境风险，仅预估不准确哈！ ---  ## 怎么用 打开 [amichinaflagged.com]( https://amichinaflagged.com) 就行，页面自动检测 9 项浏览器信号，加权打分（ 0-100 ），分数越高越可能被 Claude 标记为中国用户。 每一项信号都有权重和说明，看完就知道自己哪个信号在拖后腿： - 时区（ 26%） - 浏览器语言（ 20%） - 系统语言列表（ 12%） - 中文字体（ 16%） - 键盘布局（ 6%） - 屏幕色深（ 4%） - 硬件并发数（ 4%） - 触摸支持（ 4%） - 代理/VPN （ 8%） 也支
