Yahoo Pipes

*** The pipes didn’t come out yesterday, so those of you who have already heard about them, can simply skip this post.

But those who didn’t, are about to find out something wonderful!

The pipes are a web service from Yahoo and can be accessed by going to http://pipes.yahoo.com/pipes/

As an example of what it can do, let’s take today’s featured pipe: eBay price watch. Apparently, it gives you information about certain items from ebay, found by certain keywords that lie in a certain price range.

Without any tools at all, finding this information would require going to eBay, searching for items, sorting, finding the ones you want, and repeating that over and over again. If you are decent programmer, you could easily make a PHP script or something that does it for you: goes to eBay, fetches a page using a search request, parses it and so on. It is doable, but is it worth the trouble?

Well with yahoo pipes a script like that takes no more than 10 minutes to create! It is all because instead of writing code, you are combining structural blocks that process information in certain ways, which can include search/replace, regexps, combining functions, well basically any kind of aggregation you could possibly imagine.

Yahoo pipes are based on RSS, so the most used output method from the pipe is an RSS channel, which, if we are talking about the eBay example, could be imported into your favorite RSS reader.

Basically any data from any webpage, RSS channel or any url can be inserted into a yahoo pipe and converted to the format you want. Several sources of data can be used, records can be combined, removed, parsed, and so on, with limitless possibilities. And, what is more important, all the above is done simply, fast and visually, which, besides the development speed, also gives you a lot of room for experimentation and creativity.

(And no, I don’t work for Yahoo, it’s just that this service is really a great contribution for human kind :P)

And I haven’t even told you the best part: Yahoo pipes support information io in JSON and if I remember correctly, even PHP-serialized, which, combined with its possibility to fetch anything that has a url, effectively means that you can create your own modules for pipes that can do anything that pipes cannot do already, making the service omnipotent.

If nothing else, it is a great way to test new ideas without having to write a single line of code.

You seem not only to use Internet Explorer, which is by far a joke when it comes to browsers, but to even use an old version of it!
