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.
That is what Kalev Leetaru, a data scientist at Washington's Georgetown University, believes may be possible. Using a tool called Google Big Query, designed for interrogating vast collections of data, he has been sifting through a database of events stretching back to 1979.
This is GDELT, which has collected media reports of events from innumerable sources in more than 100 languages for 35 years. "What we did here," Leetaru explains, "was use this tool to shove in a quarter of a billion records and use this massive piece of software to just in a few minutes sift out the patterns in this data."
What he says he found was complex patterns of events repeating themselves over the years. He has looked at recent events in Egypt , in Ukraine, in Lebanon and tried to draw common patterns.
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.
Android everywhere at Google I/O
Put a couple of thousand developers from around the world in a huge hall, show them some under the bonnet improvements in the software tools they use every day, and pause after each sentence to bathe in the applause. That's the basic recipe for Google I/O which is aimed at the development community, not at consumers.
But Google knows that these days the world is watching too - so it has to sprinkle the conference's opening keynote with a little stardust in the form of some stunts and a few product announcements. Two years ago a live demo with skydivers jumping out of planes and streaming video from Google Glass set the bar very high indeed.
