Twitter's most serious security crisis

At 0430 this morning I was in a hotel in the French Alps waiting for a bus to take me through a blizzard to Geneva Airport and home.

Checking my email on my phone I found two messages from Twitter - each telling me that my password had been reset "as a precautionary security measure".

Apple revenues miss expectations

After seeing Apple's shares plunge nearly 30% - a move based almost entirely on sentiment rather than hard information - investors finally have some data to assess.

Happy Birthday, Breakfast - and newsroom computers

Happy Birthday to BBC Breakfast. It is 30 years since the UK's first early morning television news programme went on air - and it has got me feeling pretty nostalgic. Because it was at Breakfast Time - as it was then called - that I first got my hands on a computer back in 1983.

I'd arrived in a job as a sub-editor in the BBC TV newsroom at Television Centre, from a regional newsroom where the air was thick with cigarette smoke and the sound of clattering typewriters. The TV Centre operation was much bigger - but the technology was hardly any more sophisticated.
