China's Blogging Revolution

China has an estimated 30 million bloggers - a surprising statistic in a country which is well known for government censorship of the internet. Even more surprisingly, blogging is now being adopted by the country's politicians. The Communist Party secretary of the district of Suqian - Zhang Xinshi - has started an official blog and is encouraging other local party officials to follow suit.

With its focus on land use and best practice in chicken farming Mr Zhang's blog may not be the most exciting in the world but it sets an interesting precedent. In this week's programme Adam speaks to Jane Macartney, The Times reporter in Beijing about the growing popularity of blogging in China.

Adam is also joined by Russell Davies whose entertaining café review blog eggbaconchipsandbeans has become a book and was shortlisted for last year's Blooker Prize. He considers what makes a good blog and gives a few tips on how to make your blog stand out from the estimated 80 million blogs which now exist worldwide.

Cinemas Project a Digital Future

The UK's largest cinema chain has announced that two of its major multiplexes are to be the first in Europe to go completely digital. Odeon Cinemas already has 30 digital projectors across the UK but these will be the first two cinemas to dispense with celluloid film altogether.

Adam is joined by Helen O'Hara of Empire Online to ask what difference digital will make and if this signals the end of the reel for old-style projectors and celluloid.

Q & A

This week PC Doctor Simon Zerafa is focusing on backing-up your data.

Question:
Ed Davies asks: "I have a problem with my memory stick. It's a NewLink USB 2.0 Flash Drive (1 GB) and I use it to keep a back-up the documents on my laptop. However, on several occasions recently I've put into a PC (both my laptop and other computers) and they have shown the memory stick as blank and unformatted. They've also offered to re-format the device. Can you suggest what the problem is?"

Simon says: It sounds like Ed's memory stick is just plain broken. This might because it's been physically damaged or electrically damaged internally. The other possibility is that the flash mechanism within the drive might have reached the end of its life: each memory location on the drive can withstand about ten thousand rewrites, so if the drive is heavily used it may simply have worn out.

In this week's programme Simon also discusses the importance of keeping back-ups of the data on your computer. Whether it's documents, photos or music you can save yourself a lot of pain and trouble by making regular back-ups, either on a flash card, an external hard drive or CDs and DVDs.
