SparkGap - an agentic linear algebra experience Hey everyone, I'm building sparkgap.ai , an interactive tutor for linear algebra. You fill in the matrices/vectors, the LLM gives you hints until you get it correct. The hope is that it will get smarter over time from the context of which questions were missed/answered correctly. As you master concepts, the progress ring next to each concept will slowly fill in. Hopefully it should be very difficult to get to full mastery. Feedback and qu

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。

Rather than vibe coding I'd suggest to actually learn and understand the basics which won't take long btw and then vibe code so you can atleast talk to your agent properly.

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
