Twitter, reformatted. I wrote a Yahoo! Pipe to clean up Twitter’s RSS feeds—removing the username prefix and filtering out items that begin with “@” or “RT”.. # 18th March 2010, 1:10 am


If you’re just linking to the stuff that people are all talking about on Twitter or that floats to the top of Hacker News, you may as well give up on your blog, as far as I’m concerned. Everybody already sees that stuff. You have to dig deeper to offer more interesting information, and an RSS reader is the best tool you can use for that purpose.

Inside Upgrading our RSS feeds. The Guardian now offers full-content RSS feeds of pretty much everything for which we have the necessary rights (no ads yet, but they’ll be added soon). Adding “/rss” to the URL in various places on the site will get you feeds for sections, subjects, contributors and more. # 24th October 2008, 11:08 am

FriendFeed Blog: Simple Update Protocol. FriendFeed infamously poll RSS feeds on the 43 services they support millions of times an hour in an effort to keep their content as real-time as possible. SUP is a new proposal by FriendFeed for a sort of “master feed” of changes to a site—instead of hitting the Flickr feed for each of their users they would just poll Flickr’s SUP feed every minute or so to find out who had uploaded a new photo, and only retrieve the RSS feed for those users. # 28th August 2008, 12:16 pm

Flickr Developer Blog: API Responses as Feeds (via) Flickr API calls that return a “standard photos response” (e.g. and flickr.favorites.getList) can now output eight different feed formats as well, including Atom, RSS flavours, geoatom, geordf and KML.

RSS Duplicate Detection. “Detecting duplicate items in an RSS feed is something of a black art”. I hadn’t realised quite how involved such a basic function of an aggregator could be. # 22nd January 2008, 8:11 pm


Updates to template_utils. James Bennett’s Django template_utils library now provides tags for consuming external RSS and Atom feeds. Combine with template fragment caching for an instant mashup written just using templates. # 10th December 2007, 3:25 pm

Does the idea of redefining the role of the Internet browser appeal to you? Do the terms HTTP, RSS, Microformats, and OpenID, excite you? If so, then this just might be the opportunity for you.

If you write a spec, write a validator alongside. How much pain could have been spared with early versions of RSS if we’d had a common, agreed upon validator. In short, it’s the test suite that ultimately decides the spec.

PHP Library Tips

Kellan Elliott-McCrea (author of the popular Magpie RSS parser): A Few Tips for Writing Useful Libraries in PHP. Kellan makes the interesting observation that PHP encourages a culture in which most development occurs in the context of either full applications or C extensions, with few people devoting themselves to releasing libraries.

RSS2 modules

It seems RSS 2.0 has the capability to support modules (I was under the false impression that this ability was restricted to RDF modules in the rival RSS 1.0 specification). Following a post by Mark Pilgrim on B-linking (the blogging equivalent of a B-movie) Dave Winer has released a draft of blogChannel, the first ever RSS 2.0 module.

Python RSS locator

Mark Pilgrim has written an ultra-liberal RSS locator (in Python, naturally). I guess he had to scratch an itch. The amount of work it puts in to locating an RSS feed for a site is astonishing, especially when you consider how short the actual code is.
