HowToWhistle：像唱 KTV 一样练习吹口哨 一直想提高吹口哨技巧，搜了一圈发现网上的教程都是文字和视频，练的时候根本不知道自己吹得对不对。 想到可以像 KTV 一样，有个音轨对比，于是干脆自己搓了一个练习网站：[https://howtowhistle.org/]( https://howtowhistle.org/) 核心思路是用浏览器的麦克风做实时音高检测，你对着麦克风吹，页面会显示你当前的音高和目标音的偏差，类似 KTV 唱歌时的实时评分。功能大概有： - 实时音高反馈，能看到自己吹的是哪个音、偏高还是偏低 - 从单音长音开始的渐进式练习，到音阶、再到简单旋律 - 纯前端实现，声音不上传，无需注册 目前还比较简陋，欢迎大家试玩和提建议。

Built a free toolkit that grew into 5 sites, 200+ tools, no signup required I started this a few days ago to build a free invoicing tool for freelancers because everything I found was gated behind a signup wall or a "free trial." It turned into a small portfolio of 5 sites, each aimed at a different kind of solo operator: Ledgerline: invoicing, contracts, and tax calculators for freelancers Rentline: rent increase letters, late fee calculators, and lease guides for landlords Sellerline:

Just shipped something on @commonsmade and I’m genuinely hyped. Introducing Starbound Python It’s a small interactive world where you help a robot buddy named Nova rescue lost stars by writing real Python commands. You type a line of code, hit run, and watch the map react in real time. Simple commands, instant feedback, space vibes. I built the whole thing inside the Commons/VibeFi harness. No fighting with deployment, no separate backend setup, just vibe → iterate → ship. The free compute + built-in tools made it feel almost unfair how fast it came together. This is exactly what I think the future of building should feel like: An AI coding environment that doesn’t just help you write code, but actually lets you launch it, share it, and (eventually) earn from it. If Cursor or Claude Code had a built-in accelerator and 24/7 playground for vibecoders… this is the closest thing we’ve got right now. Go play with Nova for a bit. Write a few lines.
