A computing revolution in schools
This is the week when a revolution begins to sweep through schools in England. It involves a whole new way of teaching children about computing - but I suspect many parents, and even some teachers, know very little about this important moment in education.
As children from five upwards return to school, they are going to have to start learning how to program - or to "code" to use the trendy term which seems to upset some old-school programmers. This is the result of the new national curriculum for computing that is being introduced in England this term.
In the words of the curriculum document, the aim is to "ensure that all pupils can understand and apply the fundamental principles and concepts of computer science". Before considering just how well-placed schools and teachers are to make this happen, it is worth remembering how we got here.
It is just four years since two leading figures in the games and visual effects industries produced a document calling for a transformation in the way computing was taught in the UK. Ian Livingstone and Alex Hope's Next Gen report was sparked by concerns that their industries were not succeeding in finding the skills they needed to prosper.
But, aside from their practical business needs, their vision of a much more creative and in-depth computing education chimed with the concerns of many pupils - and some teachers - about ICT teaching. This subject had fallen into disrepute in many schools, seen as a fairly undemanding course in office - or rather Microsoft Office - skills, which would not help you get into a good university or a decent job.
Can computers replace historians?
All kinds of big claims have been made about the potential of Big Data. It seems it can predict the course of an election, map the spread of flu, even help police to solve crimes.
But here is the biggest claim so far - crunching through the big data of history can help us spot patterns and work out where the world is heading next.
Teenagers and the news game
Any parent of a teenager, particularly one of the male variety, will know that their conversation can be, well, limited. So my wife was surprised earlier this week when our 16-year-old son suddenly asked her what she thought about "this terrible stuff that's been happening in Ferguson".
There followed an apparently well informed account of events in the US town where a young black man had been shot dead by police. She went on to discuss with him America's troubled past when it came to race relations, and more words came tumbling from this often monosyllabic young man.
Cambridge - making a noise about tech
With a world-class university, a clutch of billion pound businesses, and a constant stream of young graduates with bright ideas, Cambridge should be unchallenged as the UK's top technology cluster. But in recent years it's struggled to make its voice heard above the hubbub from London's TechCity, which has had the backing of the government and plenty of its marketing muscle.
Cambridge has also suffered from a lack of venture capital, and that has meant plenty of its young tech firms have headed to London, because that's where the money is. But today a new venture capital fund Cambridge Innovation Capital unveils its plans to change that.
JustPark and the sharing economy
The "sharing economy" is the latest trend on the lips of every digital strategist, in the tradition that brought us Web 2.0, the Cloud and Big Data. It refers to companies such as AirBnB, which helps people to "share" their homes with holidaymakers or Uber and Lyft, which allow drivers to "share" their cars with passengers.
I've been somewhat cynical about this term because it seems to imply that these fast-growing Silicon Valley businesses are engaged on some charitable mission, rather than simply spotting a gap in the market and making huge piles of cash from exploiting it.
HP and Autonomy bitter battle
Autonomy was one of the jewels in the crown of the British technology industry, a business based on the expertise of some of the brightest minds to have emerged from Cambridge University.
It may not have been a household name, but it was in the FTSE 100, it sponsored Spurs and its chief executive Mike Lynch was one of the great and good, a non-executive director of the BBC, on the board of the British Library and an advisor on scientific policy to the Prime Minister.
Facebook expands Africa push
It's the new frontier for the internet - connecting billions of people in Africa and Asia who have yet to sample the delights of the digital world. Through an organisation called Internet.org, Facebook has put itself at the forefront of this mission.
Today it unveils a clever plan to get millions of people in Zambia online. It is without doubt a laudable philanthropic mission - but in the long run it could also be hugely important to Facebook's growth.
Hype and hi-tech
Predicting the future shape of technology is a fool's game. If you believed the forecasts of future-gazers when I was growing up, we would all be taking holidays on the moon, consuming our meals in tablet form and enjoying a 10-hour working week by now.
And even very recent predictions seem to be going awry. Figures last week from Apple showed iPad sales slowing, and growth in the overall tablet market is looking less than spectacular, so the idea that the conventional desktop PC is in its death throes now seems to be a bit oversold.
National roaming - a bad call?
It sounds a great idea - allow anyone finding it difficult to connect to their mobile phone network to roam to another network to make a call.
It's called national roaming but from what I'm hearing the mobile operators will fight tooth and nail to stop something they regard as impractical and counterproductive.
Tweeting the World Cup
This has been the week the United States finally got football - or soccer, as they still insist on calling it.
As the USA team progressed to the knock-out stage, the story has led the breakfast TV shows and been the subject of a diatribe by right-wing columnist Ann Coulter, who sees US interest in the game as a sign of the nation's moral decay.
