PicLocation - 上传照片， AI 告诉你它在哪拍的 大家好，最近做了个小工具 PicLocation： https://piclocation.com [解决什么问题] 看到一张照片想知道在哪拍的，但照片没有 GPS 信息（截图、微信转发压缩过、元数据被抹掉）——传统 EXIF 查询工具就无能为力了。PicLocation 不读元数据，直接用视觉模型分析画面里的地标、建筑风格、植被、路牌、地形这些线索，推测拍摄地点，返回 GPS 坐标、城市、国家和置信度，标在地图上。 [使用门槛] - 免费无需注册，游客每天 2 次分析 - 支持 JPG / PNG / WebP ，最大 8MB - 上传的图片最多保留 7 天后自动删除（见隐私政策） [实现] 前端 TanStack Start + React 19 ，部署在 Cloudflare Workers 全家桶（ D1 / R2 / 队列），分析用的是视觉大模型，标准模式出结果很快。核心逻辑是让模型读图并输出候选坐标 + 置信度，再按置信度展示。 [坦白说] 有明显地标的照片（

I built a Google Maps rank tracker that compares mobile and desktop results street by street I built a Google Maps rank tracker that shows mobile vs desktop rankings street by street — looking for blunt feedback Google Maps rankings are much more local than most reports make them look. A business can rank #2 from one street and become almost invisible a few blocks away. Mobile and desktop results can also tell completely different stories. I kept seeing tools reduce all of this to a sin

Wanted to head to Jubilee Hills tomorrow, couldn't understand what's going on. So, as any dev would, I vibe-coded an app that approximately tells me how to get there. Maps the official route shared by @HYDTP Give it a try 👇 #Hyderabad

Built a mountain-bike service-tracker with no accounts and no server-side data nothing to breach, I don't have your data. Garage stays on-device, cloud backup is encrypted on your phone before it leaves. Built with Claude behind a strict test+CI gate.

用 Antigravity Vibe 了个免费无限玩的地理猜图站，全球 Street View 随机降落 大概一个月前迷上了"看街景猜地点"这类地理游戏，但主流的那几个不是要订阅 就是要登录，免费版还有每日次数限制，玩不过瘾。 于是基于一个开源项目搭了个站：World Guesser 。 玩法：Google Street View 随机把你扔到地球某个角落，你根据路牌、植被、 驾驶方向、电线杆、车牌这些细节判断自己在哪，然后在地图上落点，越准分越高。 和主流竞品比，我做了几个刻意的取舍： - 完全免费，无限玩，没有每日次数限制 - 不用注册、不用登录，打开就能玩 - 暂时不挂广告，先把体验做好 - 经典单人模式，多人对战和每日挑战均已上线 技术栈是 Astro + Vue + Cloudflare Pages + Cloudflare Workers ，加载很快，手机浏览器也能流畅玩。 solo 搞的第一个版本，肯定有不少不足，欢迎试玩后直接吐槽，每条评论我都会看。 地址： https://playworldguesser.com

Geography/History game: LifeGuessr! Hi all! I worked over the last 3 months on this game: lifeguessr.com The concept is very simple: you get a birthdate, a deathdate (if relevant), and a map, and your goal is to identify the historical figure these details pertain to. Multiple hints are available to make it a bit more fun I have expended it to a wide collection of figures, including contemporary ones. I also had a bit of fun with some custom themes, rewards, etc. This game is comple
