Did you know?

There are competing claims for the innovator of the first antivirus product. Possibly the first publicly documented removal of a computer virus in the wild was performed by Bernt Fix in 1987.ClamTk 4.08 virus scanner running on Ubuntu 9.04. An antivirus program to counter the Polish MKS vir was released in 1987. Dr. Solomon's Anti-Virus Toolkit, AIDSTEST and AntiVir were released by in 1988. Dr. Ahn Chul Soo (Charles Ahn, founder of AhnLab Inc) in South Korea also released the Anti-Virus software called 'Vaccine in June 10, 1988. By late 1990, nineteen separate antivirus products were available including Norton AntiVirus and McAfee VirusScan. Early contributors to work on computer viruses and countermeasures included Fred Cohen, Peter Tippett, John McAfee and Ahn Chul Soo.

Before Internet connectivity was widespread, viruses were typically spread by infected floppy disks. Antivirus software came into use, but was updated relatively infrequently. During this time, virus checkers essentially had to check executable files and the boot sectors of floppy and hard disks. However, as internet usage became common, initially through the use of modems, viruses spread throughout the Internet.

Powerful macros used in word processor applications, such as Microsoft Word, presented a further risk. Virus writers started using the macros to write viruses embedded within documents. This meant that computers could now also be at risk from infection by documents with hidden attached macros as programs.

Later email programs, in particular Microsoft Outlook Express and Outlook, were vulnerable to viruses embedded in the email body itself. Now, a user's computer could be infected by just opening or previewing a message. This meant that virus checkers had to check many more types of files. As always-on broadband connections became the norm and more and more viruses were released, it became essential to update virus checkers more and more frequently. Even then, a new zero-day virus could become widespread before antivirus companies released an update to protect against it.

Capoeira

Capoeira is an Afro-Brazilian art form that combines elements of martial arts, games, music, and dance. It was created in Brazil by slaves brought from Africa, especially from present day Angola some time after the 16th century. It was developed in the regions known as Bahia, Pernambuco and Rio due Janeiro. Participants form a roda, or circle, and take turns either playing musical instruments (such as the Berimbau), singing, or ritually sparring in pairs in the center of the circle. The sparring is marked by fluid acrobatic play, feints, and extensive use of sweeps, and headbutts. Less frequently used techniques include elbow strikes, slaps, punches, and body throws. Its origins and purpose are a matter of debate, with theories ranging from views of Capoeira as a uniquely Brazilian folk dance with improvised fighting movements to claims that it is a battle-ready fighting form directly descended from ancient African techniques.

Historians are divided between those who believe it is a direct descendant of African fighting styles and those who believe it is a uniquely Brazilian dance form distilled from various African and Brazilian influences. One popular explanation holds that it is an African fighting style that was developed in Brazil, as expressed by a proponent named Salvano, who said, "Capoeira cannot exist without black men but its birthplace is Brazil".

The word "Capoeira" derives from the native-american language Tupi-Guarani words kaápuéra (past aspect marker), meaning "formerly a forest". Another claim is that given that capoeira in Portuguese literally means "chicken coop", it could simply be a derisive term used by slave owners to refer to the displays as chicken fights.

How To Handle Stress

One of the most significant problems human beings face as a general population is how to handle stress. As a life & career expert, and an acclaimed advice columnist, I have compiled eleven of the most significant ways that you can reduce stress in your life. You may not always be able to make stress dissappear, but you can manage it with some very simple techniques.

1. Talk! Don't hold all your feelings within! Discuss your stressful feelings with someone you trust who will listen without being judgmental or pressuring you to their own point of view. Even if you can't change the immediate situation, talking about it helps alleviate some of the tension you may be feeling. Supplement the verbalizing with something physical: write it out, exercise or hit a pillow.

2. ACT! Be willing to take risk and make change, no matter how small. Try to change the stressful situation, or at least some part of it. Moving forward in small ways helps you feel empowered and in control. Put one foot in front of the other to move in a positive direction. Soon, the stress will lessen.

3. LISTEN TO YOUR BODY! If you learn about how your body reacts to stress, you can also learn how to counter that stress. Learn to listen to your body's signals and find ways to reduce your stress, even if it's just "taking five" to clear your mind. Relaxation exercises (E.g. Yoga, meditation, physical exercise) help, too.

4. BE IN CHARGE! Discover what you need to feel good about yourself and get your needs met. Another way to reduce your stress is to find an interest, hobby or activity where you feel in charge and call the shots. If you really feel out of control, don't stay silent and alone! Seek guidance from someone who is qualified to help you get through the obstacles, and move forward again. If you can't find someone qualified in your neighborhood or you don't feel as though you can talk to someone

5. DON'T OVERWHELM YOURSELF: If you are stressed and overwhelmed, perhaps you are trying to handle too much. Rid yourself of extra duties that aren't necessary or important. Learn how to delegate and how to say "no" without feeling guilty. Ask for help if you need it.

6. GET AWAY: Sometimes a change, however small, can do wonders for your spirit. Forget it all for a while--escape! Go somewhere new for a few hours, or a few days if you can afford to. If not, it may be helpful just to "get away" to a warm bath for a little while!

7. PRIORITIZE: You may not be able to avoid all the responsibilities obligations you currently have, but you can learn how to complete them without resentment and consciously choose how you will handle them.

8. EXTEND YOURSELF: Make your own life better by making someone else's life better. Give of yourself. Volunteer! You will feel empowered, positive, important...and you will be!

9. MAKE SUCCESS HAPPEN! If you can't change the world, change yourself! Learn how to love yourself as you are, while you work towards your goals. Then, make a commitment to yourself to start improving the things about yourself and your life that (you believe) need it. Instead of immediate, dramatic change, learn to enjoy the journey of lifelong self-improvement. You are always a work in progress.

10. SOCIALIZE: Spend time with family and friends for love and support. Don't be afraid to enjoy yourself! Appreciate friendship and let others know you care about them, too. Love may not conquer all, but it's a great start!

11. LEARN HOW TO BE HAPPY: One thing all of life's winners have in common is a sense of well-being, a positive attitude and realistic goals. Focus on the good things about yourself, and in your life. Nobody's perfect. Learn to enjoy the "little things" that make you happy. Count your blessings. Every day, write down on a slip of paper one thing you are grateful for, even if it's just a sunny day, a friend's phone call, your cat's happy purr. Put this "blessing" in a jar along with a dollar or more. Do this for one month. At the end of the month read all those slips of paper and you will realize that life is better than you think! Use the money to do something really special for yourself, or donate it to charity.
