Why NetNewsWire Is Not a Web App

2025-10-08T16:12:14+00:00

In the wake of Apple removing ICEBlock from the App Store, Brent Simmons talks about why he still thinks his veteran (and actively maintained) NetNewsWire feed reader app should remain a native application.

Part of the reason is cost - NetNewsWire is free these days (MIT licensed in fact) and the cost to Brent is an annual Apple developer subscription:

If it were a web app instead, I could drop the developer membership, but I’d have to pay way more money for web and database hosting. [...] I could charge for NetNewsWire, but that would go against my political goal of making sure there’s a good and free RSS reader available to everyone.

A bigger reason is around privacy and protecting users:

Second issue. Right now, if law enforcement comes to me and demands I turn over a given user’s subscriptions list, I can’t. Literally can’t. I don’t have an encrypted version, even — I have nothing at all. The list lives on their machine (iOS or macOS).

And finally it's about the principle of what a personal computing device should mean:

My computer is not a terminal. It’s a world I get to control, and I can use — and, especially, make — whatever I want. I’m not stuck using just what’s provided to me on some other machines elsewhere: I’m not dialing into a mainframe or doing the modern equivalent of using only websites that other people control.

Building and deploying a custom site using GitHub Actions and GitHub Pages

Building and deploying a custom site using GitHub Actions and GitHub Pages

I figured out a minimal example of how to use GitHub Actions to run custom scripts to build a website and then publish that static site to GitHub Pages. I turned the example into a template repository, which should make getting started for a new project extremely quick.

I've needed this for various projects over the years, but today I finally put these notes together while setting up a system for scraping the iNaturalist API for recent sightings of the California Brown Pelican and converting those into an Atom feed that I can subscribe to in NetNewsWire:

I got Claude to write me the script that converts the scraped JSON to atom.

Update: I just found out iNaturalist have their own atom feeds! Here's their own feed of recent Pelican observations.

Footnotes that work in RSS readers

Footnotes that work in RSS readers

Chris Coyier explained the mechanism used by Feedbin to render custom footnotes back in 2019.

I stumbled upon this after I spotted an inline footnote rendered in NetNewsWire the other day (from this post by Drew Breunig):

Since feed readers generally strip JavaScript and CSS and only allow a subset of HTML tags I was intrigued to figure out how that worked.

I found this code in the NetNewsWire source (it's MIT licensed) which runs against elements matching this CSS selector:

sup > a[href*='#fn'], sup > div > a[href*='#fn']

So any link with an href attribute containing #fn that is a child of a <sup> (superscript) element.

In Drew's post the HTML looks like this:

<!-- Footnote link: -->
<sup id="fnref:precision" role="doc-noteref">
  <a href="#fn:precision" class="footnote" rel="footnote">1</a>
</sup>
<!-- Then at the bottom: -->
<div class="footnotes" role="doc-endnotes">
  <ol>
    <li id="fn:precision" role="doc-endnote">
      <p>This is the footnote.
        <a href="#fnref:precision" class="reversefootnote" role="doc-backlink">&#8617;</a>
      </p>
    </li>
  </ol>
</div>

Where did this convention come from? It doesn't seem to be part of any specific standard. Chris linked to www.bigfootjs.com (no longer resolving) which was the site for the bigfoot.js jQuery plugin, so my best guess is the convention came from that.
