Mengapa Mata Kucing Bersinar?
Mengapa mata kucing bersinar di malam hari?
Agar dapat memburu mangsanya di saat gelap, kucing sering membuka matanya lebar-lebar. Mata yang terbuka lebar tersebut dimaksudkan agar setiap cahaya yang ditangkap dapat masuk sebanyak-banyaknya ke dalam mata. Inilah yang mungkin menjadi penyebab bersinarnya mata kucing pada malam hari.

Mark Twain
Samuel Langhorne Clemens was born in Florida, Missouri, on November 30, 1835. During his school days, he was often mischievous and inattentive. Therefore, he left school when he was only twelve years old. But... many years later he became a man of many interests and occupations.
He began his career as a printer, then became a pilot of a Mississippi riverboat. Next, he also worked as a journalist, travel writer, and publisher. He wrote a number of articles, short stories, and novels. Some of his great works are The Adventures of Huckleberry Finn, The Adventures of Tom Sawyer, Life on the Mississippi, The Prince and the Pauper, and A Connecticut Yankee in King Arthur's Court.
Mark Twain was a pen name of Samuel Langhorne Clemens. This name came from his riverboat days. At that time he was measuring the depth of the water which was called "marking the twain."
Mark Twain died in 1910. Now his name is very popular. He becomes one of America's greatest writers. If you want to know more about him and his works, I suggest you read one or more of his works.

Operating System
What is an operating system?
When a computer is turned on, it searches for instructions in its memory. Usually, the first set of these instructions is a special program called the operating system, which is the software that makes the computer work. It prompts the user (or other machines) for input and commands, reports the results of these commands and other operations, stores and manages data, and controls the sequence of the software and hardware actions. When the user requests that a program run, the operating system loads the program in the computer’s memory and runs the program. Popular operating systems, such as Microsoft Windows and the Macintosh system (Mac OS), have a graphical user interface (GUI)—that is, a display that uses tiny pictures, or icons, to represent various commands. To execute these commands, the user clicks the mouse on the icon or presses a combination of keys on the keyboard.
