做了个反应速度测试站, 5 个工具+17 个小游戏,求各位帮忙看看 前段时间看了个小游戏站赚美元的教程,想着自己也试试手。没搞太复杂的——先做了几个认知测试工具,又嵌了些免费小游戏,搭了个站。 地址:checkreaction.com ( https://checkreaction.com/ ) 目前有这些: - 反应速度测试,5 轮取平均,带年龄基准对比 - 瞄准训练,30 个随机目标,测速度和精度 - 打字速度,30 秒 WPM - 序列记忆、数字记忆两个记忆测试 - 17 个 iframe 小游戏,纸牌、台球、消消乐、Cut The Rope 这些 技术跟 FH6Wiki 一样简陋——纯静态 HTML + 原生 JS ,扔 Cloudflare Pages 上。反应测试就一个 4.5KB 的单文件,也扔 GitHub 开源了。 为啥做这个 顺手查了下关键词难度。"reaction time game" KD 只有 4.8/100 ,排第二的是个 DR=0 、8 个月的新站,体验分只有 22 。第六名是个床垫公司。Google 甚至拿 Red

Hiya! So I've been playing around with having Claude make videos for a bit now even had some success posting the results to TikTok (and setup a whole pipeline so Claude can generate and post autonomously).

It uses GLM-5.2 fast via Fireworks to generate the scripts and image prompts and, like I said, Nano Banana 2 Lite for the images, gpt-4o-mini-tts for the narration, and ffmpeg to string it all together and add the Ken Burns zoom effect (which still has a shake I haven't been able to get rid of). The video compilation proved to be the blocker once the rest was in place, but I was able to speed that up by putting it on a 64 vCPU EC2. The cost might be the most interesting aspect as the short form videos tend to be about 25 cents. Almost 90% of that is the images, which are 3.336 cents a piece. Of course, running
