Swarm Intelligence
I recently read an interesting article from the Economist about a type of artificial intelligence called swarm intelligence. Swarm intelligence models the behavior of ants and birds to solve complex problems and increase the efficiency in a system. Applications of swarm intelligence include the routing of a fleet of delivery trucks to the proper destinations and the routing of information in a digital communication network.
Here is the link. Enjoy!

WSJ Subscription - How to Access Subscriber Content for Free
The wall street journal has an interesting method of price discrimination. Let me explain: Some of the articles that you click on from the WSJ homepage are "Subscriber Content," meaning only users who pay a weekly fee can see the entire article. Otherwise, you can only read the first couple of paragraphs, or so it seems... in actuality, all you have to do is copy and paste the title of the article into a Google search, click the WSJ link, and voila. You have access to the entire article.
It turns out that the weekly subscription fee is helping subscribers avoid a couple of clicks and a google search, which amounts to perhaps 10 seconds with a high speed internet connection. If users are reading a high volume of articles, then the time savings might be worth it. But for the majority of us, we can take a few extra seconds to do a Google search.
I would love to know why this is WSJ's strategy and how long it has been this way. I imagine it is an effort to drive more traffic to the site. It is also possible that WSJ subscribers tend to have higher incomes and thus more disposable income to throw around. Still, I am curious what those subscribers would think if they found out they have been paying for access to free content. Will this strategy catch up with WSJ once word spreads? Does anyone know of other media companies doing similar things?

Dropbox.com - A Great Timesaver
If you work on multiple computers (i.e. home computer, laptop, mobile device, etc.) I highly recommend using Dropbox.com. Dropbox is a file syncing site that will eliminate the need for a USB flash drive.
What Dropxbox does:
What Dropbox does not do:
What Dropxbox does:
- Allows you to access and edit the same file from different computers
- Syncs files in the dropbox to each computer that has software installed
- Provides a web-based interface that you can access from any computer with internet access
- Gives users two gigabytes of free data storage space
- Enables users to share a certain folder in their dropbox with other users (great for collaboration!)
What Dropbox does not do:
- Does not allow two users to simultaneously edit a file (i.e. Google Docs)
- Does not allow users to store an unlimited amount of date
