浏览在黑客新闻上提交的 Substacks。
cartucho1 · HN
I made an HN clone that lists only Substacks posted here. - Why? Over the years, I've discovered some great blogs here, so I thought it would be nice to have a filter for them. - Why only Substacks then and not blogs more generally? Because it's easy to query for "substack.com" in the public HN Algolia API (see below). Plus, hnblogs was already taken :) - What about substacks on custom domains then? At the bottom of the page there is a form to submit a custom domain. The site attempts to auto-validate that it is a Substack. If that fails, it is marked for manual review (which I'll do every once in a while). Approved ones will be included in the results. - How? I use HN's Algolia API to fetch substack stories by searching for "substack.com" in the url. I do this via a CloudFlare worker that has 3 separate cron triggers: (1) fetches new stories every 10 minutes and saves them in a KV store. (2) runs 2 minutes after the first, computes hot stories from new ones by simulating HN's scor

混合鸟鸣和自然音创建个性化白噪音助眠和专注。

做了一个*鸟鸣*主题的白噪音网站：可以模拟自然环境、还有猜鸟游戏 大家好，最近做了一个小网站：**Bird Song 鸟鸣** 地址： https://bird-song.org 它主要是一个鸟鸣主题的+自然背景音网站，适合当作专注、放松、助眠时的背景声音。 目前有几个功能： - 鸟鸣混音器：选择不同鸟类，调节音量，生成自己的自然声景 - 自然背景音：可以混入森林、小雨、海浪、春风等环境音 - 鸟类库：可以按物种浏览鸟鸣和相关介绍 - 猜鸟游戏：听声音猜是哪种鸟 我做这个网站的初衷是，平时工作或者休息时会听白噪音，但很多白噪音网站比较机械，我也没找到可以自选鸟类的白噪音网站，自己就来搞了一个，嘿嘿 截图：  ![混音器截图]( https://assets.bird-song.org/images/screenshots/2026-07-12/mixer-zh.png
