Hacking Computers and Ethics essays

Hacking Computers and Ethics essays What comes to mind when you hear the word hacker? For most it means stealing information through the Internet, gaining illegal access to another persons PC, or simply - disruptive behavior using a computer. The subject of hacking is no secret to the general public. Many people have been exposed to it by a bad experience or through the news and media. The idea of hacking that is stuck in the minds of people is that of which they have seen in the movies. The movies portray hackers as young and devious criminals. However, in reality these individuals are, talented people who use their abilities to find new and challenging ways to change how computers work. According to the Cult of the Dead Cow, a hacking organization, true hackers do not get into the system to erase everything or to sell the information to someone else. They get in there to satisfy their curiosity to see if getting into the system can be done, to search around inside of a place they have never been, and to explore the little nooks and crannies of cyberspace. Of course there are those who erase files from other peoples computers, steal information from cyberspace, and vandalize web pages. These people are not hackers, as the media calls them, they are known as crackers. Hackers use their vast knowledge to better the computer industry. Hacking started even before computers became popular. The earliest forms of hacking started in the 1960s, when AT & T was the only phone company. Back then the telephone was taken for granted and the way the phone system worked was a complete mystery. Phones were considered an early form of the computer. Those that tried to understand the phone system more and find ways to make free phone calls from pay phones were known as phreakers. This was an amateur form of telephone hacking. The way this was done was by using the old rotary dial pay phones with three slots for a nickel, dime, and quarter. The phreaker wo...

Sports-Related Science Fair Project Ideas

Sports-Related Science Fair Project Ideas Stay away from the typical, overdone science fair cliches, instead create something that combines sports and science for your science fair project.   Some Ideas to GetYou Started How does the material from which a baseball bat is made affect performance? How does a wood bat compare with an aluminum bat?Does altitude affect the height of a ball bounce (for example, a golf ball)? If an effect is seen, can you attribute it to the effect of gravity or atmospheric pressure?Examine the effect of energy bars on performance. Pick a sport. Is there a difference in performance if you use a protein-boosting energy bar versus a carbohydrate-boosting energy bar?What is the effect of using a corked baseball bat compared with a normal one?Does drinking an energy drink (or sports drink) affect reaction time? memory?Are there really streaks in baseball? Or is it simply chance?Compare energy drinks based on cost, taste, short-term effect, and long-term effect.Which sports drink contains the most electrolytes?How is ball diameter related to the time it takes the ball to fall?Does the length of a golf club affect the distance you can hit the ball?Does a swim cap really reduce a swimmers drag and increase speed? How does exercise affect heart rate? This project is especially good if can track data over a longer time frame.Does exercise affect reaction time?Does regular exercise affect memory?At what slope angle is the mechanical advantage of a bicycle lost, as compared with running?Compare different brands of balls for a sport (like baseball or golf) for cost versus performance.Do helmets really protect against a crash (presumably tested with a stimulant like a watermelon)?What is the best air pressure for a soccer ball?How does temperature affect the accuracy of a paintball shot?Does altitude, temperature, or humidity have an effect on the number of home runs seen at a baseball diamond?Does the presence or absence of a net affect free throw accuracy?Measure the effect on peripheral vision from wearing different types of corrective eyewear (such as glasses). Does an athlete experience a noticeable improvement when peripheral vision is increased?Is there an effect if you fill an inflatable ba ll with a different gas than air (such as nitrogen or helium)? You can measure height of bounce, weight, effect on passing, and how long it stays inflated. Tips for Choosing a Sports Science Fair Project If you are an athlete or trainer, pick the sport you know best. Can you identify any problems to be examined? A good science fair project answers a question or solves a problem.When you have an idea, consider how to design an experiment around it. You need data. Numerical data (numbers and measurements) are better than qualitative data (greater/lesser, better/worse), so design an experiment that gives you data you can graph and analyze.
