Hi HN, This is ProofTree, and in TLDR: it is a platform where you can chat with an AI to do math, the way you already do, with context-awareness and knows how you personally do math, connected to the fora of other live human mathematicians. So, when you are talking to an AI about a proof at 3 am, and you need a human expert looking at it, or a discussion around it, like you do on StackExchange, this is it! You need an approved email account to use it, so please write here if you would live to try it out.

做了一个会把微积分解题过程“动起来”的计算器,想听听大家的意见 最近做了一个微积分学习工具 CalculusMate 。 起因是我发现很多计算器只给最终答案,即使列出步骤,也很难看出表达式究竟是怎样一步步变化的。所以我尝试把求导、积分和极限的计算过程做成可以逐步播放的形式。 目前支持: - 导数、积分和极限计算 - 展示每一步使用的规则 - 动画演示表达式的变化 - 支持常见数学符号键盘 - 中英文界面 - 基础计算无需注册 可以从这个页面体验: https://calculusmate.com/step-by-step 免费版本: https://calculusmate.com/free 目前还处于早期阶段,我比较想知道: 1. 解题步骤是否足够容易理解? 2. 动画是帮助理解,还是会让页面显得太复杂? 3. 还希望优先支持哪些题型? 欢迎直接指出问题,尤其是计算结果、移动端体验和表达不清楚的地方。

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

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

Block distracting websites by solving math or coding puzzles.

TLDR built a Chrome site blocker that lets you into distracting sites only after you do some math or simple coding (JS only right now). Direct link to extension (the site just gives you more context): https://chromewebstore.google.com/detail/sphinx-earn-your-di... Philosophically it's a speed bump rather than a hard gate, because you'll eventually tear a gate down but you'll leave a speed bump. I've always eventually removed site blockers, or just had them become a nuisance that I reflexively dismiss before getting to distracting sites. Site blockers don't really reduce the "start navigating to a distracting site" muscle memory, and they eventually just become annoying. Dopamine is a hell of a drug. At the same time, I've been getting frustrated that my intermediate/advanced math skills have atrophied, and becoming more senior in my career (plus AI...) has caused my coding skills to atrophy even further. Realistically I'm not going to force myself to do math or coding exercises aft

Built a free tool site to help my brother study — now has 100+ tools, would love feedback My brother's in high school and needed something more visual to study chemistry, physics, and math, so I used Claude to build him a simple site with interactive calculators and visualizers. I'm not a programmer or from a tech background, so without AI this wouldn't have happened, at least not this fast. It ended up helping him a lot more than I expected, so I kept expanding it, added a bunch of other
