CAPTCHA: Telling Humans and Computers Apart Automatically

A CAPTCHA is a program that protects websites against bots by generating and grading tests that humans can pass but current computer programs cannot. For example, humans can read distorted text as the one shown below, but current computer programs can't:

The term CAPTCHA (for Completely Automated Public Turing Test To Tell Computers and Humans Apart) was coined in 2000 by Luis von Ahn, Manuel Blum, Nicholas Hopper and John Langford of Carnegie Mellon University.

Improve Self Confidence

Here are some quick tips to improve your Self Confidence. If we are committed to have a healthy self confidence there are many things you can do every day to boost your self confidence, each small steps that will help you to reach your goal. The good news is that self-esteem is not fixed and can be improved, try some of the steps below to boost your confidence and self-esteem.

1) Identify your successes. Everyone is good at something, so discover the things at which you excel, then focus on your talents. Give yourself permission to take pride in them. Give yourself credit for your successes. Inferiority is a state of mind in which you've declared yourself a victim. Do not allow yourself to be victimized.

2) Look in the mirror and smile. Studies surrounding what's called the "facial feedback theory" suggest that the expressions on your face can actually encourage your brain to register certain emotions. So by looking in the mirror and smiling every day, you might feel happier with yourself and more confident in the long run.

3) Exercise and eat healthy. Exercise raises adrenaline and makes one feel happier and healthier. It is certainly an easy and effective way to boost your self-confidence.

4) Turn feelings of envy or jealousy into a desire to achieve. Stop wanting what others have just because they have it; seek things simply because you want them, whether anybody else has them or not.

5) When you're feeling superbly insecure, write down a list of things that are good about you. Then read the list back. You'd be surprised at what you can come up with.

6) Don't be afraid to push yourself a bit - a little bit of pressure can actually show just how good you are!

7) You can try taking a martial arts or fitness class/course (or both). This will help build confidence and strength.

8) Invest in some new clothing and donate some of your old clothing to send a message to yourself that you both look sharp and feel sharp.

9) Try to make yourself talk positively at all times. When you hear yourself saying you can't do something, stop and say you can. Unless you try, you will never know whether you are able to or not.

10) Don't get wrapped up in your mistakes and dwell on bad points; they can contrast your good points or even give you something to improve. There's no feeling like being good at something you were really bad at.

11) Don't confuse what you have with who you are. People degrade their self worth when comparing possessions.

12) Surround yourself with nurturing friends, not overly critical individuals who make you feel inadequate or insecure. This could do great harm and damage to your self confidence.

Tips to Take Control of Your Weight

FatboyAnyone who is overweight will testify that losing weight is not as easy as it seems. The people that are lean, or have gone from fat to skinny will say it’s just a matter of motivation and elbow grease. Although it is not as simple as that. Our environments have waged war on us. Their weapons are sedentary lives and trans fats of mass destruction. All is not lost though, here are some quick simple tips to get ahead!

Substitute Water. Our bodies are about 65-70% water. It follows that water would be not only essential, but the best possibly choice of liquids to ingest. In fact, our bodies will sometimes simulate a hunger response, when in reality the body is craving hydration. When hungry, drink a glass or two of water to check if it suppresses your hunger.

Chew Your Food. Chewing our food very slowly and deliberately has several benefits that are often overlooked. It gives us the ability to relax, and enjoy our meal. Slow chewing is the first, and highly important, step in a complex system of digestion. Besides, if we eat slowly, we might feel full before finishing the whole meal, and can leave the rest for the next meal.

Exercise daily. How silly of me to include something as obvious as exercise. I did a 30 day trial with waking up, and walking for 30 minutes first thing in the morning. My journal records that I was feeling amazing during the period of time that I was following this habit.

Publicize your intentions. Start a blog, join a forum, and have other people keep you accountable to help. Tell other people your plan, it would help you get the motivation to go with it!

Create a food schedule. Plan your day so that you’re eating at approximately the same time each day. This scheduling will incorporate itself into your circadian rhythm, and aid in digestion.

Do not over eat. Know your limit and stop eating when you are full. I have often been a victim of wanting to finish a meal so that it doesn’t go to waste. This has left me with many a stomach ache. Next time, doggy bag it for later, and don’t hurt yourself!

Choose your snacks wisely. Put down the Lays® and cheese puffs. Pick up the apple and baby carrots. Make the right decision, I know you can do it.

Lifestyle. Remember, it’s not about special diets, or special exercise programs. The real secret is in turning your health into a lifestyle, and focusing on this healthy lifestyle with every choice you make.

Tips for good sleep

Stick to a schedule. Erratic bedtimes do not allow for your body to align to the proper circadian rhythms. Mum was right when she set a time we always had to go to sleep as kids. Also, make sure you try to keep the same schedule on weekends too, otherwise the next morning, you’d wake later and feel overly tired.

Sleep only at night. Avoid daytime sleep if possible. Daytime naps steal hours from nighttime slumber. Limit daytime sleep to 20-minute, power naps.

Exercise. It’s actually known to help you sleep better. Your body uses the sleep period to recover its muscles and joints that have been exercised. Twenty to thirty minutes of exercise every day can help you sleep, but be sure to exercise in the morning or afternoon. Exercise stimulates the body and aerobic activity before bedtime may make falling asleep more difficult.

Taking a hot shower or bath before bed helps bring on sleep because they can relax tense muscles.

Avoid eating just before bed. Avoid eat large meals or spicy foods before bedtime. Give yourself at least 2 hours from when you eat to when you sleep. This allows for digestion to happen (or at least start) well before you go to sleep so your body can rest well during the night, rather than churning away your food.

Avoid caffeine. It keeps you awake and that’s now what you want for a good nights sleep. We all know that.

Read a fiction book. It takes you to a whole new world if you really get into it. And then take some time to ponder over the book as you fall asleep. I find as I read more and more, regardless of the book, I get more tired at night and so find it easier to fall asleep. Different for others?

Have the room slightly cooler. I prefer this to a hot room. I prefer to turn off the heat and allow the coolness to circulate in and out of the windows. If I get cold, I wear warmer clothes. It also saves on the bills as you’re not going to require the heat all night long.

Sleep in silence. I find sleeping with no music or TV on more easy and restful. I guess others are different, but sleep with no distractions is best for a clearer mind.

Avoid alcohol before bedtime. It’s a depressant; although it may make it easier to fall asleep, it causes you to wake up during the night. As alcohol is digested your body goes into withdrawal from the alcohol, causing nighttime awakenings and often nightmares for some people.
