Pick a Test - 快速在线测试,即时获得结果。

做了一个在线反应、记忆与专注力测试网站 最近做了一个叫 [PickTests]( https://picktests.com/) 的在线测试站。 反应时间、序列记忆、瞄准训练这些东西,网上其实已经有很多了。真正让我想重新做一遍的,是不少页面要么堆了很多不必要的内容,要么广告和装饰比测试本身更抢注意力,到了手机上也不一定顺手。 所以我给这个项目定了一个比较克制的方向: 不急着增加更多测试,先把每一个已有的测试认真做好。 目前上线了 6 个测试: - 反应时间 - 瞄准训练 - 序列记忆 - 数字记忆 - 多目标追踪 - 斯特鲁普测试 首页:[反应测试]( https://picktests.com/zh/) 网站使用纯 HTML 、CSS 和 JavaScript ,没有账号系统。成绩保存在当前浏览器,打开页面就可以开始。 我现在主要在调整这些细节: - 操作是不是足够顺手 - 测试节奏会不会太快或太慢 - 结果能不能一眼看懂 - 动效和反馈会不会太多 - 手机、平板和电脑上的体验是否一致 目前最想先做好的页面

I don’t know why isn’t it getting that much attention it’s actually a big deal for people who do vibe coding, for people like who develop micro apps daily. As a teacher it’s so ise to just tell students to go to and practice tables… It’s so amazing

A couple weeks ago we were on vacation with friends, and after the kids were asleep we played games -- mostly Qwirkle, which I had never played and am terrible at. I don't care about being terrible at games, so I made a web version to keep playing after vacation: build lines of tiles that share a color or a shape, 2-4 players (or add bots). I wanted it to be low friction, so there are no accounts. Your identity is an anonymous id in localStorage, and you can move it to another device by scanning a QR code or hitting a unique url. Start a game and text someone the link (game slugs are semi-memorable three word phrases), or "Play the computer" and you can play immediately against bots. Games are async-friendly with web push for turn notifications. The stack is one Node process on a small VM, Next.js + Socket.IO, no database. The server and the client use the same engine so moves validate optimistically, and the bots go through the same functions, so bot moves are always legal. State is

About to launch alarm reminders in my productivity app. Thoughts? About to add alarm-based reminders. Not push notifications... real alarms that ring even when your screen is locked. You can set one for anything. A task, a habit, any date on your calendar. "Dentist 20 Nov. at 5 pm" → alarm set. "Take meds at 9 am every day" → alarm set. I built this because push notifications just aren't enough. Most people ignore them. So what if you could set an actual alarm for the thi
