In many of your classes, your instructor lectures on or makes a presentation about a topic, usually one that’s related to the current subject you’re studying. During a class lecture, your job is to listen actively and to take notes to reinforce what you’ve heard and jog your memory about the key points being presented.

Instead of writing down every word, listen — really listen — and put the information in perspective. What’s truly important to understand and remember? What’s not? Look for alerts from the lecturer, who may indicate significant information by repeating it, giving multiple examples, writing on the board, gesticulating or speaking forcefully, or giving word clues (”Two important reasons . . .” “Opposing viewpoints from . . .” “The result underscored . . .”).

Because I haven’t gotten a TV set in my house, I was trying to watch BBC World via Internet. Without luck, the official site of BBC World didn’t put the video stream as a free service, and I also tried lots of online TV sites, all of them has a invalid stream feed for BBC World. However, I finally found a p2p TV software written by Zhejiang University (China).

Here is the Java program written by me to simulate the Brownian motion. In this prac, I tried to use double buffering to improve the performances, but actually it is triple buffering.

The Arenal Volcano is the only volcano in Costa Rica constantly active since it woke up after 400 years with the big 1968 eruption producing huge ash columns, explosions & glowing red lava almost every day. It is considered one of the ten most active volcanoes in the world. This country is about beaches, rainforest and the spectacular Arenal.
