"There are big dogs and little dogs, but little dogs must not fret over the existence of the big ones. Everyone is obliged to howl in the voice that the Lord God has given him."

— Anton Chekhov, as quoted in Ivan Bunin's About Chekhov

LI Chengping currently works as both an R&D engineer and a market manager at a sensor company, and received a doctoral degree from the Scientific Visualization Group at IAPCM.

This is where I write about scientific visualization, laser & thermal physics, and fiber-optic sensing — notes from research, engineering, and the space in between.

Why RSS, even today? / 这年头还用 RSS?

Most of what you see online today has been picked for you by a recommendation algorithm optimized to keep you scrolling and clicking — not to show you what you actually want to see. Over time this tends to trap you in a feed that just reflects your existing preferences, often without you noticing.

RSS works differently: you choose which sites to follow, and new content reaches you exactly as published — no algorithm re-ranking or filtering it along the way. What you see is what you subscribed to. And it's a one-time setup: subscribe once and it keeps working indefinitely, no re-following or re-confirming needed.

You don't need to install anything new: Thunderbird (the email client) has built-in RSS support (File → New → Feed Account); classic desktop Outlook supports it too; Vivaldi's browser sidebar has a built-in RSS reader. If you use something else (Chrome, Safari, the new Outlook, and Apple Mail have all dropped this feature), a dedicated reader is still lightweight to add: NetNewsWire (free, open source) on iPhone/Mac, Feeder (free, open source) on Android, or Feedly/Inoreader if you want one app across platforms.

Plenty of serious sites still support it: every GitHub repository, every subreddit, every YouTube channel, Wikipedia, and most news organizations maintain an RSS feed by default. This isn't a legacy feature — it's a low-cost way to take back control over what you see, instead of letting an algorithm decide for you. Worth the few minutes it takes to set up.


你现在看到的大部分信息,是被推荐算法挑出来喂给你的——它们优化的目标是让你多停留多点击,不是让你看到你真正想看的东西,看久了容易被圈在一个只反映自己既有偏好的信息茧房里,自己却不容易察觉。

RSS 走的是另一条路:你选你想跟踪的站点,新内容出来就原样推给你,中间没有算法二次筛选排序,看到的是你自己订阅的东西。而且这是一次性的动作——订阅一次长期有效,不需要重新关注、不需要反复确认。

不一定要装新软件:Thunderbird(邮箱客户端)自带 RSS 功能(File → New → Feed Account);经典版 Outlook 桌面版也支持;Vivaldi 浏览器侧边栏内置了 RSS 阅读器。如果你用的是这几个之外的工具(Chrome、Safari、新版 Outlook、苹果 Mail 都已经砍掉这个功能),装一个专门的阅读器也很轻量:iPhone/Mac 上 NetNewsWire 免费开源,安卓上 Feeder 免费开源,或者两边都通用的 Feedly、Inoreader。

支持 RSS 的不只是小众博客:GitHub 的每个仓库、Reddit 的每个版块、YouTube 的每个频道、Wikipedia、大多数新闻机构,都在默认维护自己的 RSS feed——这不是一个过时的功能,是从"被动被喂"切回"自己决定看什么"的一个低成本入口,花几分钟设置一次是划算的。
