Best of this Week Summary 21 September - 27 September 2009

• Always feeling a bit less up-to-date when using RSS/Atom feeds? Well, convince your RSS/Atom provider to implement the PubSubHubBub protocol: it provides a callback-hook, which when registered to as feed subscriber, causes an immediate update (ping) to the subscriber (instead of waiting for the next RSS/Atom feed request).
  Or will rssCloud be the winner of this realtime RSS extension? Here's the basic (simpler) flow of rssCloud:
  
  
  Differences between the two are described here (including some issues) and here. A real old-fashioned flame-war has even started between the creators of the two protocols.
  And a good comparison which explains quite well why PuSH is the better choice of the two. Note that both protocols seem to be server-to-server only! (e.g think when you're behind a firewall or NAT...)
  See this article for an explanation of the PuSH flow of notifications/information in below's diagram:
  
  
  Update: PubSubHubbub explained by co-creator Brett Slatkin (an engineer at Google).
  
  
• Want to get to know Hadoop? In short "Hadoop allows you to write and run your application in a distributed manner and process large amounts of data with it. It consists out of a MapReduce implementation and a distributed file system." Check the rest of this introduction for more details.

Best of this Week Summary 24 - 30 June 2007

• Nice use of RSS: use it to publish your nightly build results. They then use the (commercial) product Confluence to build a wiki page out of it.
  

• Interesting write-up of one of the developers of the Digg comments system. Very AJAX and PHP orientated solution. Notice for example that the DOM is created mostly dynamically and there is 4x as much Javascript code than PHP code for the comments functionality! For interesting detailed design desicions made (main question to anser: how to the commenting more complex and simpler at the same time), see this link, also mentioned in the article.
