Really Simple Syndication (RSS)

Really Simple Syndication (or previously, RDF Site Summary) is a type of web feed commonly used by news outlets and blogs, as an alternative way for readers to subscribe to updates. The data in these feeds (title, author, post date, article contents) are stored as machine-readable XML.

Big Algorithm doesn't want you to know this, but RSS subscription software - known as news aggregators - can check these feeds for updates, and deliver them right to the user for free, all without ads, filter bubbles or tracking software getting in the way!

History

The internationally recognized symbol of RSS.

The first version of RSS was 0.90 and originally called RDF Site Summary. Developed by Netscape, it was based off an early working draft of Resource Description Framework, but ultimately took on an incompatible life of its own.

Eventually Netscape abandoned the project after releasing version 0.91. In this power vacuum, competing developers to released their own successors: One published RSS 1.0 and the other RSS 2.0, with the 2.0 spec being the most widely used today.

Another popular XML-based technology - Atom - was developed a few years later to address some of the 'bugginess' in RSS, and is similar enough to be placed in the “RSS family.” Most decent aggregators support both RSS 1+2 & Atom feeds. For more information on the differences between RSS and Atom, read this detailed comparison.

Structure

One day, you may have something that you want people to be able to keep up with via feed readers & aggregators. It is really simple to do with both RSS & Atom, and most modern aggregators support both formats.

RSS 2.0

If you're familiar with HTML, RSS looks kinda similar. Any feed conforming to this format should be readable by any compliant aggregator:

rss2example.xml

<?xml version="1.0" encoding="UTF-8" ?>
<rss version="2.0">
<channel>
 <title>RSS Title</title>
 <description>This is an example of an RSS feed</description>
 <link>http://www.example.com/main.html</link>

 <item>
  <title>Example Entry 1</title>
  <description>Here is some text containing an interesting description.</description>
  <link>http://www.example.com/blog/post/1</link>
  <pubDate>Sun, 6 Sep 2009 16:20:00 +0000</pubDate>
 </item>
 
 <item>
  <title>Example Entry 2</title>
  <description>Here is different text containing an interesting description, so you can see how this loops.</description>
  <link>http://www.example.com/blog/post/2</link>
  <pubDate>Sat, 5 Sep 2009 16:20:00 +0000</pubDate>
 </item>
 
</channel>
</rss>

This layout is very simple to understand: Every feed has a <channel> with its own metadata tags (such as <title>, <description>, <link>, etc). Entries, or posts, or updates, or whatever you want to call them, are represented by a list of items, and each <item> has tags for the title, description and link as well.

If you have a website, some software can automatically detect your RSS feed, if you embed the following tag in the <head> section of your HTML template:

<link rel="alternate" type="application/rss+xml" title="Name of Feed" href="https://domain.com/path/to/feed.xml">

However, it is not to be understated that RSS can be used to pipe more things into an aggregator than just updates for web pages. For more information on the available tags you can use, read the RSS 2.0 specification or W3Schools' RSS Guide.

Atom

Atom arose to address some of the perceived shortcomings of RSS, and confusion between the different competing versions of RSS. To some it provides a more “uniform” experience with their newsreaders. There's no right or wrong answer as to which is better, as different developers may find different uses for each.

The basic structure of an Atom feed looks like this, and it loops the same way as an RSS feed:

atomexample.xml

<?xml version="1.0" encoding="utf-8"?>
<feed xmlns="http://www.w3.org/2005/Atom">
 
  <title>Example Feed</title>
  <link href="http://example.org/"/>
  <updated>2003-12-13T18:30:02Z</updated>
  <author>
    <name>John Doe</name>
  </author>
  <id>urn:uuid:60a76c80-d399-11d9-b93C-0003939e0af6</id>
 
  <entry>
    <title>Atom-Powered Robots Run Amok</title>
    <link href="http://example.org/2003/12/13/atom03"/>
    <id>urn:uuid:1225c695-cfb8-4ebb-aaaa-80da344efa6a</id>
    <updated>2003-12-13T18:30:02Z</updated>
    <summary>Some text.</summary>
  </entry>
 
</feed>

If you have a website, some software can automatically detect your Atom feed, if you embed the following tag in your <head> section:

<link rel="alternate" type="application/atom+xml" title="Name of Feed" href="https://domain.com/path/to/feed.xml">

For more information on Atom feeds, read the Atom Specification or W3C's Introduction to Atom.

RSS as a Field Utility

The value of RSS to AnonOps agents cannot be understated. As many sites have RSS (or Atom) feeds, you can centralize the updates of all your favorite sites, authors, streamers, developers, and whatever else, all in one place - saving the need of having to check a bunch of individual websites or even opening your browser.

However, RSS has security benefits as well. Because it is simple XML text, that means you don't have to worry about potentially dangerous remote media compromising your machine or tracking your movements. Datacenters, ISP's & web server operators can still see your address checked the feed, but it is otherwise much harder to fingerprint you.

In fact, those inclined to unplug will recognize other benefits of using aggregators as well - especially if beforehand they got their news via social media algorithms & corrupt platforms like Google. With direct subscription to RSS feeds, you will no more have to deal with “recommended” news, or AI arbitrarily censoring your feed.

Some aggregators (such as Newsboat) allow you to pipe these updates to other utilities. This lets you do really cool things like use yt-dlp to download Youtube videos right from your news reader and open them in a local media player, or track GitHub project commits and clone them into clean testing environments.

With RSS feeds and the right aggregation software, the sky is truly the limit with how to integrate it into your operations.

Application-Specific Instructions

To subscribe to AMI's Recent Changes feed, point your feed reader to:

Browser-Based Applications

Many websites exist which offer the ability to let users subscribe to RSS/Atom feeds. While this is convenient for sure, it completely defeats the purpose of unplugging from the machine. Just install an aggregator, and enjoy the greater convenience of never having to open your web browser.

Mozilla Thunderbird (Multiplatform)

For those just starting out with RSS, the email client Mozilla Thunderbird doubles in a pinch as a powerful news reader. It is easy to install and well documented, and the interface is well-suited to displaying structured feeds.

For installation instructions, visit Thunderbird.net.

Newsboat (Linux, MacOS & BSD)

This section needs expansion. You can help by adding to it.

WeeChat (Linux, MacOS & BSD)

The IRC client WeeChat has a plugin that allows you to subscribe to RSS feeds. This is super useful if you want to compartmentalize subscriptions related to your IRC friends (their blogs or Youtube channels, perhaps) in the same place you chat with them. First, make sure plugin installation is enabled, then install the rssagg plugin:

/set script.scripts.download_enabled on
/script install rssagg.pl

Have WeeChat monitor feeds with:

/rssagg add <feed_name> <feed_URL>

Pull up internal documentation:

/help rssagg

More WeeChat shortcuts can be found in the Configuring WeeChat guide.
