Security and Privacy Vulnerabilities of In-Car Wireless Networks

While reading this article, I learned many things about tire pressure management systems. I did not know that tire pressure devices utilize wireless devices and that these devices could be used to track where the driver goes. I also never thought that someone could/would use a tire pressure device to misinform the driver that their tire is low in order to rob the driver. These were both very frightening facts. I like how this article first mentioned the benefits of using more wire in cars, but also went in depth about the vulnerabilities of using this technology.

The Magical Number Seven, Plus or Minus Two

The magical number 7 states that the most the human brain can remember is around 7 items at a time. This is helpful information for any student. I tend to get frustrated with myself if I cannot remember many things all at once. Now I know that there is a natural reason for this. I liked this article. I found it interesting to read about the limits of the human brain. I'm also interested to see how this will relate to software engineering. 

Planning for Failure in Cloud Applications

            In this article, Mike Wood talks of a notion mentioned in Chapter 11 of the textbook: survivability. Wood goes in depth on how to keep systems running even when they fail. I learned about many preventive techniques to combat software failure in this article. Automation was something I did not know about before reading this article. I did not know that if you tried to recover a system manually that the recovery time would increase. I feel the idea of automation would be very useful. It is almost as if you are coding the system to treat itself. I also did not know scripts can be utilized in this. I thought scripts were just for managing directories not for restoring  full systems. I did not know they were this powerful. I also learned how to deal with transient errors by using re-try code. I never thought to add a re-try to my code before. This article was very insightful.
