最近做了一个「冥想知识地图」+ 一个「10分钟快速冥想工具」,已经完全开源👇 10分钟快速冥想: 冥想知识地图: GitHub: 之所以做这个小产品,是因为越来越多人想开始冥想,但真正动手时会卡在两个地方: 1. 不知道从哪开始——听过很多术语,却分不清「正念」和「观想」到底有什么区别,也不知道自己当下最需要哪种。 2. 觉得时间太长、门槛太高——很多人一听要坐20-30分钟就直接放弃了。 所以我顺便做了一个「10分钟就能完成一次完整冥想」的工具:打开就能直接用,选好类型,跟着引导做完就走,不需要任何准备。 这些也是我自己和身边朋友在尝试冥想时反复遇到的问题,所以想做一个既帮你「搞懂」又帮你「马上能用」的东西。 而「知识地图」是吧把冥想里最容易懵的概念(呼吸法、身体扫描、正念、慈心、观想……)做成了可左右滑动的知识地图,每个都有解释、步骤、场景和常见误区。 配套10分钟的训练,让你知道为什么、怎么做。 之前我写过一篇冥想文章,如果对冥想不太了解的可以先看这个:

I built this a year ago, just as a fun experiment, and posted it on my portfolio. It was getting a lot of monthly traffic so I built it as a stand alone app and monetized it. Slowly but surely it’s growing :) Mobile app launches soon too.

A friend taught me a Slovenian card game two days ago. GPT-5.6 Sol helped me turn our argument into an AI opponent. Two days ago, a friend taught me Sedmice, a traditional card game we play in Slovenia. The rules are simple, but we quickly got into an argument about the best moves. Naturally, I decided the reasonable way to settle it was to build an AI opponent. I wrote out the rules, project specification, architecture, and implementation details, then handed the logic to GPT-5.6 Sol. Ab
