Browse and discover Substacks that were submitted to Hacker News.
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

Place predictions on future outcomes across politics, sports, and crypto on a BNB-native prediction market.

预测市场最贵的,从来不是判断错。 而是当你发现异动时,聪明钱已经买完了。 所以,我做了一个双平台工具: 「信号罗盘」 Polymarket 500 个热门盘口 500 个热门盘口 两边各 50 个聪明钱地址 异动热度、收益曲线、每日评级和近期操作逻辑,全部放在同一个页面。 它不是喊单网站,也不承诺收益。 我们只想把分散的信息,变成更早、更清晰、可以验证的交易信号。 目前免费开放测试。 你最希望下一个加入什么功能:地址提醒、跨平台价差,还是聪明钱跟踪? #Polymarket #Predict #预测市场

Visualize and predict weather with on-device calculations and custom aggregation modes.
__mp · HN
I built my own weather prediction / visualization app: https://wx.rsp.li (on-device temperature lapsing, on device interpolation modes, user-selectable aggregations, etc…). One of these days I should do a writeup. I also asked Claude to build a photo gallery for me https://places.pascalspoerri.ch (HDR, map support, similar images)

最近看到 @dappOS_com 一个作品挺有意思 一个主流币交易共振信号Agent,通过 dappOS Coding 快速完成 链接: 这个案例的价值,不在于又做了一个行情页面,而是在于它展示了一种新的 AI Agent 构建方式 过去开发一个交易辅助工具,需要先处理数据接口,再搭建前端交互,编写指标逻辑,最后不断测试优化。 对于很多有交易想法的人来说,真正困难的不是没有策略,而是从想法到产品之间隔着一整套开发流程 dappOS Coding 改变的,就是这个过程 通过自然语言描述需求,就可以快速生成对应功能模块 像这个交易共振信号案例,本质上就是把市场数据、技术指标和信号逻辑结合起来,形成一个面向交易场景的辅助工具 它并不是替用户直接交易,也不是承诺预测市场 更重要的价值在于 帮助交易者降低信息处理成本 在 Crypto 市场里,行情 24 小时运行,大量数据、新闻、价格变化不断涌入 普通用户很难持续人工筛选有效信息 AI Agent 可以承担其中一部分重复工作: 监控市场变化 整理关键数据 输出信号参考 辅助交易决策 这也是为什么最近 AI + Crypto 的结合越来越受到关注 OKX 推出 AI 与交易生态结合 @BNBCHAIN 也在推动更多项目加入 BNB Agent Studio,鼓励开发者围绕交易、情感陪伴等方向构建 AI Agent 整个行业正在从AI 能聊天进入AI 能完成任务的阶段 而 dappOS Coding 展现出来的方向,是降低 Agent 创建门槛 以前一个想法可能停留在笔记里,需要开发团队才能实现 现在,更多开发者、交易者甚至普通用户,都有机会快速验证自己的想法 未来 Crypto 的竞争,不只是资产和协议之间的竞争,也会是 AI Agent 生态和应用数量的竞争 谁能让更多人低成本创造工具,谁就更有机会成为下一阶段基础设施的一部分 这个交易信号案例只是一个开始 AI Agent 正在逐渐成为连接用户、数据和链上应用的新入口
