Learn Python by solving 60 coding challenges in a browser-based editor.
u/Funny-Temporary7465 · Reddit
Built a Python learning platform because I was bored of the existing options Hey everyone, I built PyTutor, a web app to learn Python by actually writing code from the first minute instead of watching videos. 60 challenges across 6 modules, a real Python editor in the browser (runs via Skulpt, no backend needed), a live variable inspector so you can see what your code is doing as it runs, and a certificate at the end. Built it with AI-assisted coding tools, which let me focus more on the

Owl 猫头鹰 — 小红书公众号在线敏感词检测工具。我做了半年自媒体之后才发现需要规避平台敏感词,但是之前用的工具停服了,市面上其他的需要登录或者关注他们的公众号才可以使用,于是我 vibe coding 了一个敏感词检测工具,词库是根据网上找的,精简下来有 6 万多个。用了 cloudflare 的开发者穷鬼套餐,所以每人每天限制 10 次,主要是防止第三方调接口把额度耗完大家都没得用,应该对于

Like everyone on HN, I love nothing more than to (re)read my own comments. Getting my intuition that I am among the smartest, most humble, highest quality commenters on here confirmed by an LLM so capable that the US government had to temporarily export restrict it [0] seemed only natural. Having had my perfection confirmed, I decided to share this joy with you as I had a few percent usage left before a reset. I took a few prompts, then did a review of the output which resulted in Selbstbild, a BYOK (Anthropic / OpenRouter) web app that gives you a summary and assessment of your public comments by one of our machine Gods, including Fable 5 (provided your can afford that luxury at API pricing). In all seriousness, I have, for a long time, used my own comments on social media (including HN) as part of a personal needle-in-haystack test, simply because I do know my somewhat peculiar style and what I tend to write, but also because I can sometimes write in a slightly confusing manner, ma

Speak any of 24 languages with Lucia, an AI tutor that remembers your conversations.
u/emidaboi · Reddit
My English was solid on paper, but I froze the second I had to actually speak. So I built a language partner that remembers you to practice with (24 languages). Hey everyone. I'm a senior CS student, kind of obsessed with AI/ML, and a solo dev. Bit of backstory: my English was always fine, but the moment I had to actually speak, I'd freeze and I didn't really have anyone to practice with. I tried a bunch of apps and they all felt like talking to a service bot polite, generic,
