Computers store information as binary digits. We frequently explain it like a light switch. A switch can be “on” or “off”. So that switch can store two values. We represent these as numbers. A zero is “off” and a one is “on.” This is a bit. If we put two bits together, we can store up to four values (00, 01, 10, 11). If we … Continue reading Details

We’ve been using linear text for centuries. Ever since written language became — well — written, we’ve been stringing words together into sentences, and sentences into paragraphs, and paragraphs into stories or essays or arguments. It’s very familiar. Pick up a book. Start at page one. Read every word, in order, until you get to the end. It’s easy. About 45 years ago, people started … Continue reading Click Here

The Spirit of Radio

You’ve probably noticed that California is on fire. At the moment, there are ten active wildfires. Half a million acres have burned, claiming seven lives, destroying 1600 homes, and displacing almost a million people. Radio station KPBS in San Diego switched formats to 24-hour fire coverage last Sunday.

Her school district provides a web site creation tool. They can easily put announcements, homework, classroom rules, and schedule information online. They can choose the neat animated graphics that elementary schools seem to love. … Continue reading Why Blog?

Social Networking in Schools

Back in August, the National School Boards Association concluded that social networking isn’t so bad after all. The study that they commissioned found a significant disparity between the things students are doing online, the things schools are allowing, and the risks associated with participation in online social networks. The materials from an August 14 news briefing are also available online, and were used for the … Continue reading Social Networking in Schools

So Far, So Good

This is part 2 of my Linux journey. See what you’ve missed.  Ubuntu installed without any problems. Upon restarting, I logged in with the account I configured during the installation. The first order of business was fixing the video settings. I was stuck in 800×600 mode, because the installer didn’t correctly identify my video card. It took a little Googling to get it resolved, but … Continue reading So Far, So Good
