Big Brother is watching …. Really
Look at 4:39 mark in the video. The school principle actually shows how he monitors the students through the webcam in their laptops.
This internet thing will never work
An article from Newsweek (1995). The following paragraph almost seems like a sales pitch for Google that would not exist for another 3 years. [Link]
What the Internet hucksters won’t tell you is that the Internet is one big ocean of unedited data, without any pretense of completeness. Lacking editors, reviewers or critics, the Internet has become a wasteland of unfiltered data. You don’t know what to ignore and what’s worth reading. Logged onto the World Wide Web, I hunt for the date of the Battle of Trafalgar. Hundreds of files show up, and it takes 15 minutes to unravel them–one’s a biography written by an eighth grader, the second is a computer game that doesn’t work and the third is an image of a London monument. None answers my question, and my search is periodically interrupted by messages like, “Too many connections, try again later.”

Ouch!
Talk about hitting below the belt. One network adapter manufacturer frying an egg on their competitor's product. Of course the targeted company sued them right back but is their anything that can undo the following punch line:
"If you want the lowest temperatures, the best performance, and proven reliable products, come to Emulex," he says, "if you want breakfast, go to QLogic."

Lightning on a Volcanic Eruption
From NASA. [Link]
Why does a volcanic eruption sometimes create lightning? Pictured above, the Sakurajima volcano in southern Japan was caught erupting early last month. Magma bubbles so hot they glow shoot away as liquid rock bursts through the Earth's surface from below. The above image is particularly notable, however, for the lightning bolts caught near the volcano's summit. Why lightning occurs even in common thunderstorms remains a topic of research, and the cause of volcanic lightning is even less clear. Surely, lightning bolts help quench areas of opposite but separated electric charges. One hypothesis holds that catapulting magma bubbles or volcanic ash are themselves electrically charged, and by their motion create these separated areas. Other volcanic lightning episodes may be facilitated by charge-inducing collisions in volcanic dust.
