All ipv4 addresses are gone. Ipv6 is the wave of the future. Not everybody uses it.
Youtube can show us what TCP/IP internetworks look like.

Click Fraud and Grid Computing
Here is an even more sophisticated version of click fraud than we described in class last time. If one just write a program to simulate a user clicking but not buying anything, one can more easily detect click fraud. In this example, regular users are fooled into making the click happen when looking at things they were likely to buy anyway.
Grid computing accomplishes a lot in Folding@home, seti@home, and too many others. Here's a list from Wikipedia. These are examples of using crowdsourcing to solve a problem. Gamification can also be used with grid computing to encourage people to participate.

Medical IS
The LA Times recently reported that the iPad is now part of a federally approved informatics system.
An example on YouTube from 16 years ago points to the rapid change brought about by the Internet and other information systems.

RFID, IS, and Informatics
Walmart uses Radio Frequency Identification (RFID) for a variety of purposes now. They initially used RFID to streamline their supply chain during shipping and warehousing, and now they are also using them in their stores and before the goods are ever shipped to them. This article delves into the business case for Walmart pursuing RFID in their stores. RFID isn't just for Walmart. It can also be used for cows. Cows were too big a target, so they moved on to mice.
This story appearing today about Google, Microsoft, and Bing is too good to pass up. Is Microsoft using Google through internet explorer to improve Bing, or is Microsoft copying Google directly?
Also, Google just released a nifty in-browser information visualization tool for fractals.

A is for Apple and Astroinformatics
Two IS and informatics news items appeared in the last couple of days:
Steve Jobs is on leave at Apple again, and the fact that this concerns shareholders, customers, and investors illustrates the dual nature of IS.
Also, astroinformatics is in the news again as this article about Canada's astroinformatics data issues has been slashdotted.
Not all computer use in the sciences is about data management. Some of it is about computation, and the top 500 ranks the fastest computers in the world. Creating workflows and developing new applications in this environment is a problem that informaticists work with other scientists (physicists, biologists, and chemists) on.
I was saving this one for later in the semester, but the cover story on the Leo weekly this week is about LVL1, the Louisville area hackerspace, part of the maker movement.

Keeping with the Lord of the Rings theme for 1 more lecture...
A recent Communications of the ACM has this article showing the intersection of informatics and The Lord of the Rings. The link is most likely only accessible from the IU campus or through the VPN. There is a wealth of informatics content in this article:
1. The fact that new economy companies are running virtual worlds for profit.
2. That archiving such material is a complicated problem at the intersection of information systems, library science, computer science, etc. It's an informatics problem.
3. A lot of academic researchers (e.g. professors) may be interested in researching the social aspects of how people use these virtual worlds. Depending on the methods used, that could be sociological research or research in social informatics. What would the difference be?
This recent L.A. Times article shows a potential new use for BD Live Blu-ray content. Why is it posted here? What does it tell us about the New Economy or increasingly accelerated change in a digital world?
If you didn't know it before, it's official! The N.Y. Times has reported that Facebook is in a better position than MySpace.
Finally, this recent Wired article talks about the Sloan Digital Sky Survey. Finding new ways to use, visualize, and learn from this information and deal with the large amounts of data is the domain of astronomers, astro-informaticists, and computer scientists.
