One day, Jerry’s Macbook soundcard decided to kill itself. I REFUSE TO WORK. The terrified Macbook, unsure of what to do, displays an X sign on the volume adjustment button while shooting a lazer beam out of its earphone jack. Jerry, shocked at this chaos, runs to the Genius center, or the IT office and asks, “WTH is wrong with my Macbook???” The Tech guy answers, “Your sound card is broken, you have to pay $100 to fix it.” Depressed at both the absense of his Macbook and the money lost, Jerry walks home, after a depressing day.

This is a frequent issue that occurs with Macbooks. More than enough of the times, the technician would demand time and money to fix a sound card issue. However, unless the issue is terribly serious, there is a simple, nonprofessional way to fix it. So lets go:

Materials: Soundcard-Broken-Macbook, Earphone

1. Fully reboot your Macbook

2. (If the soundcard error continues) Get an earphone ready.

3. Gently wiggle the earphone plug in the jack (as if to straighten the path) <- Try numerous times, continuously checking with F11 and F12 button.

4. If its working now, congratulations. If it isn’t, repeat step 1.

5. Finally, If this wasn’t enough to fix your soundcard, Now, go ask a technician.

On March 1st, the Korean holiday, the Korean Blue House site was attacked by the Japanese forum community 2ch. Though many people are aware of this issue, not many are aware of why such a thing happened.

The issue started with the 2ch forum about a Korean killed in Russia. 2ch is an anonymous Japanese Internet forum, often thought to be the largest forum in the world. The 2ch-ers wrote derogatory comments under this forum. “Award the Russians!”, “Why is this on the news? It’s just a dog.” Although this fired up some people for revenge, these derogatory statements were common, and others ignored this discrimmination. However, to worsen the situation further, they created the rumor that the Korean figure skater Kim-Yu-Na bribed the referees (Scorers) during the Vancouver Olympics. Enraged at the 2ch-ers, the Korean netizens of DC inside and many other online communities gathered to terror the 2ch site.

A cafe formed in Naver to terror 2ch. The member count of this cafe skyrocketed, reaching more than 110,000 by the time the attack was launched. Programs were distributed, and plans were formed quickly under a person with the nickname “The Leader”. These distributed programs did not use any form of illegal codings. It just caused an infinite page refresh. By using the page-refresh-technique, these “Online Warriors” planned to overload the traffic of 2ch.

On March 1st, the members of this cafe rushed into the various servers of 2ch and started terrorizing it. The result was devastating. Within 5 minutes, half of the servers crashed. Although 2ch recovered itself at an astonishing speed, it was met with even a stronger opposition;  soon, every single server of the 2ch site crashed.

The enraged 2ch-ers attacked the Korean Blue House site.

Although both sites recovered fully shortly after, this event got the attention of the Interpol. If such an event reoccurs, it is bound to get a serious investigation by the Interpol.

Although people started criticizing both sides for wasting time on such a pointless issue, people became more interested as the situation progressed; they cheered the sides with comments like “If winning makes you an idiot and losing makes you an idiot as well, be the winning idiot.”

What is yellow dust? and how do you prevent the yellow dust from making us sick?

During the change of seasons, people are especially vulnerable to illness such as the common flu because of sudden change in environment. Yellow dust is one of these sudden change. During spring and winter time, when yellow dust is the worst, students must be especially careful to avoid being getting sick.

The yellow dust is a phenomenon that affects much of Eas

t Asia sporadically during the springtime months. The dust originates from the deserts of Mongolia, China, and Kazakhstan and are carried through strong winds that produce intense clouds of dust.

These clouds of dust are capable of producing acid rain, carrying toxic pollutants, bacteria, and viruses. Areas affected with concentrated dust experience decreased visibility and stain buildings and automobiles yellow. On the human body, it is known to cause deteriorating effects including sore throat, asthma, and o

ther various health problems. Although the Korean government is trying their best to aid the Chinese in restoring these yellow dust originating regions, this has not alleviated the problem yet.

Another popular Springtime illness is the common flu. Here’s a list of how to prevent yourself from getting the flu:

1. Wash you hands often.

Washing your hands frequently is probably the most important method to prevent the common cold. It is the most important method, simultaneously, the most effective. Even when outside, regularly washing hands, by even using a sanitizing hand wipes or a sanitizer, can be helpful.

2. Wear a mask.

Especially during winter and spring, when yellow dust is at its worst point, wearing a mask can prevent much of the dust going into the body.

3. Don’t smoke.

Smoking can often damage airways and increase the vulnerability. Even second hand smoking can be harmful. Smoking can bring the similar effect of inhaling yellow dust.

4. Throw used tissues right away

Don’t leave used tissues lying around desks and other surfaces. The viruses can be left on the surface and contaminate others who touch it. Leaving used tissues around can be another cause of spreading the virus.

6. Wear glasses, not lens.

Wearing glasses is better for the eyes than lens especially during the yellow dust season. Wearing contact lens can make the eyes more exposed to dusts because it provides no protection

7. Drink a lot of water!

Water makes up 75% of human body. The amount of water people drink is critical. Dehydration can cause tiredness, constipation, muscle cramps, irregular blood pressure, kidney problems, dry skin, etc. Drinking water is important in maintaing homeostasis the body, preventing cold.

8. Create a healthy lifestyle.

Last but not least, living a healthy lifestyle and acquiring good habits are important factors of preventing cold. Exercise, eat well. and sleep well. Physical activities and getting enough sleep will enhance the immune system.

Don’t let the yellow dust effect you! Remember these tips and stay healthy!

I came upon this topic in a conversation with Hyunwoo for some reason and thought it would be………a bit interesting to list the greek alphabets and their common usages. So here’s your list of letters and usages. <NOTE: There are definitely more usages for these alphabets. I will just be mentioning few real common ones.>

Αα (Alpha)

Ββ (Beta)

one root of a quadratic equation, β- particle (electron), β+ particle (positron), sound intensity, velocity/speed of light, elliptic latitude.

Γγ (Gamma)

Sighhh that was long. This showed me how much the Greek alphabet is being used in everyday life. By going through each one of the alphabets I knew,  I was both able to organize my mind and see for myself how much it was being used.

Try adding your own usages of these symbols!
