Yahoo Pipes was a service offered by Yahoo up until 2015. It was used by programmers and developers to manipulate, aggregate and mashup content from all over the web, create web apps and publish them.
Yahoo Pipes does not exist anymore, Yahoo shut it down. Below I will write my experience with the website and what I had used it for during the limited time I had with it. It shut down shortly after I became aware of it.
Creating a custom RSS Feed with Yahoo Pipes for my blog – Seriouslyfunnyhumor.blogspot.com
This is how to customize an RSS Feed using Yahoo Pipes; or, as I see it, create a brand new custom RSS Feed.
I discovered this when I needed my RSS Feed for my blog Seriouslyfunnyhumor.blogspot.com to not include new posts, but to include only older posts published before a certain date, and to basically be static (to not get updated). I needed this in order to set old post re-sharing through Twitterfeed…
Now, this is the Yahoo Pipes recipe I used:
In the Fetch Feed section I used this URL (RSS Feed from my Blogger): http://seriouslyfunnyhumor.blogspot.com/atom.xml?redirect=false&start-index=1&max-results=100
The parts in Red make the feed display the latest 100 posts (Because the feed by default only displays 25 posts). When the blog has over 100 posts, then change the number 100 to a larger number.
In the Filter section I used the “item.y:published.utime” – “is greater than” – “1/01/2015”
Basically, what this will do is give you all posts up to and including 30/12/2015. So when the time comes for me to change the feed to include more posts, just change the date there, and the feed will be updated up to the date you input.
Note: I’m not sure, but I may need to delete this pipe entirely and create a new one, the same one, in order to re-schedule my feed sharing on Twitterfeed. The reason is, the GUID identificators will probably remain the same in the feed after updating it, and so Twitterfeed won’t be able to find unique GUIDs for the older posts, the ones it has already shared from this feed. I have to test this out when the time comes…
Here is where I asked a questions when I was trying to figure this out: https://developer.yahoo.com/forums/#/discussion/6971/grab-feed-posts-by-date
And here’s a blog post that completed the help:

I’m just noting them here, just in case…
