Telling Time in Binary

My wife got me a binary clock for Christmas. It has a number of settings. It can tell time in 12-hour or 24-hour time and it can tell it in binary coded decimal or true binary. Now I admit that I’m not as up on binary as I should be. The days when I had…

The Internet is More Than a Library

I spent some time last week talking to some people from The Center for Innovation in Engineering and Science Education at Stevens Institute of Technology in New Jersey. They have an impressive portfolio of 20 K-12 curriculum projects that make the Internet a lot more than the simple though large library that is the extent of…

A Little History – Computers From Outside the UK and US

We pretty much teach the modern history of computers as something that happened in the United States and the United Kingdom. We talk about men like Turing and von Neumann working in the 1940’s and 1950’s on the first real computers. Oh sure we talk about older calculating devices a little big – Babbage, Leibnetz,…

Sudoku in Visual Basic .NET

I found an interesting little program that creates Sudoku puzzles in Visual Basic .NET. I have to say that I really love it. But not for the reasons one might expect. I don’t love it for the amount of cool features it has. Frankly it doesn’t have all the bells and whistles that a lot…

Field Trip to a Launch Event

There always seems to be a shortage of interesting and educational field trips for computer science programs. My students used to complain regularly that they wanted to go on a computer related field trip.  Conferences are generally in the wrong place, too expensive and way over the heads of students. There are companies who will…

Is it the computer or the programmer?

Doug over at EdTEchDev has a great set of quotes about programming and learning. I highly recommend the whole collection and think you could go there and read them all. But one of them stuck out when I read it: That’s the thing about people who think they hate computers. What they really hate is…

Two Mice, Two Cursors, One PC
