How can we keep our children safe without depriving them of all computers have to offer? Keri Facer explores how computers can be a valuable tool for learning and social interaction.
Artist Duggie Fields has recently added a computer to the tools of his trade. Duggie has been an artist for over 30 years, building up a reputation as one of the world's leading post-pop artists. He has exhibited world-wide, and his London flat acts as a mini gallery of his work.

With a few easily available tools people can reveal the stored passwords on their computer and access previously deleted data. Learn about some of the issues in data privacy and computer forensics. This free course, Introduction to computer forensics and investigations, provides practical demonstration in a clear and accessible format.
What have computers got to do with cows? Can a wooden mirror help us understand the computing behind digital image capture? Neil Rowse is the first dairy farmer in the UK to use a computerised system that gives cows control over when they are milked, and allows him to remotely monitor the welfare of individual animals. Daniel Rozin has created an computer operated mirror made from 835 tilting wooden tiles. With the help of a digital camera and a computer programme, the wooden tiles mimic the digital pixel information and tilt themselves into a ‘reflection’. This material is taken from The Open University course T224 Computers and processors.
Computers play a huge part in almost all of our lives, but how did these machines become so powerful and important? And what were some of the earliest models like? This collection of videos takes us through the Four Generations of computers, starting with Colossus, the world's first electronic computer (launched in 1944), and finishing with the BBC Micro (launched in 1981) and Fourth Generation Computers, looking at how technology changed throughout these years. Visiting locations such as The National Museum of Computing in Milton Keynes and The Centre for Computing History in Haverhill, we see an array of fascinating machines and learn about them along the way.
This material forms part of The Open University course TU100 My digital life.
Although many of the electrical goods and gadgets we buy today come in pre-sealed boxes, which makes it hard to take them apart and look inside, it's still possible to tinker in a hands on way with a lot of today's technology. The Maker Faires are celebrations of this sort of hands-on activity: have a look at the following slideshow to see what sort of things were on show at the UK's first Maker Faire in Newcastle in March 2009.
