My latest Decoded Science article, "Trace the Source of a Rumour or Epidemic via its Network", explains how a new pair of algorithms can backtrack a message in a network much more quickly than previous methods.

Marc Smith has posted a number of images like this on Flickr; they show how complicated the paths can be among Twitter users. However, so far as I know, he had nothing to do with the research paper that my article discusses.

The key breakthrough by Dr. Pedro Pinto and his team, was to avoid the need to examine every message belonging to every user in a network. How did they do this? Sorry, you'll have to read my Decoded Science article to learn more.

Publicity for my Network Tracing Article

As always, I publicize my articles in DeHaan Services ("A Faster Way to Trace Epidemics") and in my Xanga blog ("Trace Rumours Faster with a New App").

Writing Tip from Tracing Networks

Today's writing tip is more of an observation than a tip.

My editor at Decoded Science had suggested this topic and provided contact information. Dr. Pedro Pinto answered my questions quickly, and was very helpful through the brief process.

Sometimes a writing assignment is much more difficult; the source authority might not have time or interest in helping out. However, if you can ask a couple of thoughtful questions, generally they gladly help you publicize their concepts and achievements.

In summary, the writing tip is to ask your source a good question.

    Flexible Sidebar

    Weebly's "Blog Author" widget from the Blog Sidebar's Elements menu provides a lot of flexibility. You can change both the title and the text.

    It has all the capabilities for text editing that you find in most Weebly text widgets.

    At this point, I don't see a way to code any HTML in this widget.

    The "Picture" does what you expect: it displays an image of your choice. I just added my home-made picture of "Copyright DeHaan Services 2013" as the top element in this sidebar on Jan. 22, 2013.

    The "Search Box" is a "Pro" feature; if you're paying for Weebly hosting, it may be worthwhile.

    The other widgets are pre-programmed to do what they say.
