    While there are a few ways to make use of your old smartphone, one of the better ways is to convert into a dash cam (行车记录仪) that you can use on your bicycle. With the camera, you can record your rides, which is especially helpful if you are involved in a crash with another vehicle.

    To use your smartphone as a dash cam on your bike, you will need to make sure it is properly secured to your bike. To do this correctly, you must take two strips of heavy-duty Velcro (a kind of cloth used as fastening) along with two pipe Clamps (管夹) and a flat corner brace (角撑) to properly attach it. You will start by attaching the comer brace to your smartphone.

    Next, attach a Velcro strip to your phoned back. You will put the second strip on the end of the brace comer and cut any extra Velcro off and away from the brace. By using heavy-duty Velcro, you shouldn't have to worry about the camera brace must be attached to the bicycle directly.

    Take two pipe clamps so you can attach the part of the corner brace so the phone can be held up and used. The pipe    clamps must be positioned near the center of the handlebar, which will enable you to get a better picture when videotaping.

    To run a dash cam app on your old phone, you will just need to download a dash cam app onto the old phone. You will then just start the app at any time you head out on the road. There is always the chance of flaws, but you will be giving yourself a way to protect yourself in a friendly, eco-friendly manner that is much less expensive than purchasing a dash cam.

    Friendships can be difficult—because often people aren't as honest and open as they should be. Sometimes, people end up getting hurt.

    Most problems with friendships come up because people are just too selfish to care about the things that their friends need. They care about their own needs much more, which makes it hard for friendships to work. However, being selfish is part of human nature. A person is put together in order to take care of himself and his own needs, not necessarily those needs of other people. Even though being selfish is something that all humans are born with, it is something that everyone should guard against.

    The best thing to remember when you are a friend to anyone is that you need to treat your friend the same way as you'd like to be treated. This is wonderful advice for a friendship, because it is really the only way to make sure that you are giving your friend everything you would want to be given in a friendship. Whenever you have a question about how you should treat a friend, it is easy to find an answer simply by asking yourself what you would like your friend to do for you, if he or she is in your shoes.

    Even if you're always thinking about how you'd like to be treated, and your friends are too, there are issues that come up from time to time in each friendship, and it is important to understand how to deal with these issues so that you can build stronger and healthier friendships. Issues like friends getting boyfriends or girlfriends and not spending enough time with their friends, or even friends finding new friends and leaving old friends behind are issues that will probably come up with one or more of your friendships. It is important to know how to deal with these issues so that you can keep your friends and make new ones. No one wants to have a broken friendship.

    Spotify can tell if you're sad. Here's why that should scare you. Want to figure out if someone is a patient with a mental disability: Ask them what their favorite song is. A New York University study last year found that people who loved Eminem's Lose Yourself and Justin Bieber's What Do You Mean? were more likely to have trouble with mental disabilities than people who were into Dire Straits.

    Over the past few years, Spotify has been improving the ability to analyze information to help businessmen target consumers with advertisements made specially for their needs. They conclude this from the sort of music you're listening to, combined with where and when you're listening to it, along with third-party data that might be available.

    Now, to be clear, there's nothing significantly illegal about what Spotify is doing with your information. I certainly don't think that they are working with shadowy consulting firms to serve you ads selling a culture struggle while you're listening to music that suggests you might be in a terrible situation. However, I find it disappointing that our personal, private moments with music are increasingly being turned into information points and offered to advertisers.

    You can see where this could go, can't you? As ad targeting gets ever more accurate, businessmen will have the ability to target our feelings in potentially improper ways. According to one study, you are more likely to spend more on a product if you're feeling sad. You can imagine some companies might take advantage of that. And on that note, I'm feeling a little down about all this. Head off to treat myself to something expensive.

    When you are sitting in the car, do you ever notice the drivers looking over their shoulders or side to side in the car? Well, they are doing this to check their blind spots! Blind spots make driving extremely difficult and increase the potential for car accidents.

    Fourteen-year-old Alaina Gassier from Pennsylvania noticed her mother struggling with blind spots while driving their family car. So she came up with an ingenious solution that won the first place and $ 25,000 in the Broadcom Masters Competition.

    Blind spots are the areas around the car that cannot be directly observed by the driver. There are two kinds of blind spots-on the back of the car that cannot be seen with mirrors, and blind spots at the front of the car as well.

    When a driver is changing lanes, he has to look over his shoulder through the side windows to make sure that there is no vehicle in the blind spot. This invisible area is big enough to hide a car!

    The other blind spot is created in the front by the A-pillar(柱子)-the material on either side on the windshield(挡风玻璃)that holds the glass and forms the frame of the car. In some cars, this pillar can be quite thick. Usually, people or cyclists can be hidden by this pillar.

    Alaina's design was to get rid of the blind spot created by the front A-pillar of the car, the one that helps hold up the windshield.

    She put a camera on the outside passenger side of the car which then sent the photos to a projector above the driver's head. Then, she covered the inside of the pillar in a reflective fabric onto which the image was projected. Basically, her device made the pillar "see through" and removed the blind spot on that side of the car.

    Alaina's solution is very creative and could be improved by using LCD displays that will make it easier to see during day time as well.
