Blackberry phones are in the process of getting a rhythm to unlock your phone with. This type of technology would be useful to those who try to unlock their phones, but many people try to watch what password you put in so they can do it as well if they ever take your phone. However, with this rhythm that may come up it will be harder for those to try to pick up on what you are putting on your phone and it will be much more difficult to imitate it. Also, blackberry will be able to sense the touch so you do not have to make it obvious. I think this is more convenient because people won't guess your password as easily if it is a rhythm. 

Daylight saving time might say that it helps make our lives nicer and help us save energy, but in reality it is completely pointless. Daylight Saving Time was actually first suggested by Benjamin Franklin in 1784 but the idea was shot down by everyone stating that it was pointless. The Germans then used it the First World War to save coal during war time. After that everyone started using it and didn't think to change back. Today, people state that this change of time helps to save energy, promotes a healthy lifestyle, and reduces traffic accidents. First off, Daylight saving time does not in fact save energy. Recent studies show that it might reduce the US electricity usage during March and April, but only by 1%. Secondly, this does not help us to become any healthier. In fact, the clock shifts disrupt our circadian rhythms and actually spike the suicide rates and increases the number of recorded heart attacks. Daylight saving time also does not reduce traffic. Some studies show that the time change makes no difference at all while others suggest that traffic is reduced by 0.7 which is pathetic and makes no difference. I personally do not like Daylight saving time only because I loose an hour of sleep and it screws up my whole schedule because everything is off by one hour. I much prefer the clocks changing an hour behind so I get an extra hour of sleep.

This article is about how blackberry phones could have a rhythmic touch to unlock them rather than a code or face unlock. I think this is really awesome because a lot of people are blackberry users and it would be fun to have. I have a blackberry so this would want me to have a touch blackberry just so I can have an unlock like they created. This tap unlock detects the location and magnitude of your touch. This relates to the course because the blackberry is the hardware and the actual program to detect the touch is the software. You need to program the actual app for the blackberry devices.
