A Walk on the Wildside

I had thought I had seen it all. Crop circles you may be familiar with but how many of you know about ‘Warchalking’?

Should you happen to have a (WIFI 802.11b) wireless network installed in your building have you noticed any strange chalk marks on the walls outside? No? Have a good look next time you walk into the office.

Warchalking according to the Website “Is the practice of marking a series of symbols on sidewalks and walls to indicate nearby wireless access? That way, other computer users can pop open their laptops and connect to the Internet wirelessly. It was inspired by the practice of hobos during the Great Depression to use chalk marks to indicate which homes were friendly”.



Of course, the Prime Minister wishes to give all of us Internet access by 2006 but even though government is tacitly interested in the potential of ‘Public Access’ WIFI points; a subject raised in a conversation I had at No10 last year, I suspect that the joy-riding other people’s bandwidth isn’t quite what Downing Street had in mind.

Already, we have our own modest wireless ‘underground’ springing-up in the UK and if you visit www.consume.net you can see, that rather like plotting the position of speed cameras on the M25, there’s another little group of enthusiasts, mainly students, I suspect, broadcasting the locations of accessible wireless networks and inviting others to hop-aboard for the ride.

The Warchalking debate does raise a couple of interesting arguments, the first of which is the generally pathetic level of security awareness associated with wireless networks. The second questions whether ADSL is really the solution for the population as many people, including me, still can’t justify the incremental monthly cost of Broadband from home.

What if government chose to take a radical step forward and lead by example, embracing wireless networking, while simultaneously encouraging the ‘Public Sector’ hospitals, schools, town halls, universities and so on, to install WIFI Networks and somehow ‘share’ bandwidth on a local basis? Already new Wireless LAN equipment, based on the draft 802.11g specification, offering theoretical speeds of up to 54Mbps in existing 2.4GHz frequency range is being launched in the UK.

Without much doubt, 2003 will be very much the year of wireless networking and this in turn will usher-in one of those transformative changes in computing, as both multiple-device mobility and ‘always-on’ connectivity become increasingly important.

Warchalking is however an expression of a much larger problem that needs to be solved. Is the expanding wireless ‘dial tone’ a ‘free’ wave that anyone can surf and how, much like the plot of William Gibson's futurist novel, 'Neuromancer', do you prevent smarter members of the public from stealing a ride on your network?

Gibson has, by coincidence, just started his own 'Blog' and the link is given above.

So while business needs to think seriously about tightening-up any and all network security, wireless or otherwise, government needs to think about a future where wireless access is increasingly pervasive and where borrowing bandwidth from the company or hospital next-door is rather more attractive than paying £25.00 a month for a fixed-line ADSL connection.

Civilisational Data Mining

It’s a new expression I haven’t heard before. ‘Civilisational data mining.’

Let me start by putting it in some context. Every character, you or I have typed into the Google search engine or Facebook over the last decade, means something, to someone or perhaps ‘something,’ if it’s an algorithm.


In May 2014, journalists revealed that the United States National Security Agency, the NSA, was recording and archiving every single cell-phone conversation that took place in the Bahamas. In the process they managed to transform a significant proportion of a society’s day to day interactions into unstructured data; valuable information which can of course be analysed, correlated and transformed for whatever purpose the intelligence agency deems fit.

And today, I read that a GOP-hired data company in the United States has ‘leaked’ personal information, preferences and voting intentions on… wait for it… 198 million US citizens.

Within another decade or so, the cost of sequencing the human genome …

The Nature of Nurture?

Recently, I found myself in a fascinating four-way Twitter exchange, with Professor Adam Rutherford and two other science-minded friends The subject, frequently regarded as a delicate one, genetics and whether there could exist an unknown but contributory genetic factor(s) or influences in determining what we broadly understand or misunderstand as human intelligence.

I won’t discuss this subject in any great detail here, being completely unqualified to do so, but I’ll point you at the document we were discussing, and Rutherford’s excellent new book, ‘A Brief History of Everyone.”

What had sparked my own interest was the story of my own grandfather, Edmond Greville; unless you are an expert on the history of French cinema, you are unlikely to have ever hear of him but he still enjoys an almost cult-like following for his work, half a century after his death.

I've been enjoying the series "Genius" on National Geographic about the life of Albert Einstein. The four of us ha…
The Mandate of Heaven

eGov Monitor Version

“Parliament”, said my distinguished friend “has always leaked like a sieve”.

I’m researching the thorny issue of ‘Confidence in Public Sector Computing’ and we were discussing the dangers presented by the Internet. In his opinion, information security is an oxymoron, which has no place being discussed in a Parliament built upon the uninterrupted flow of information of every kind, from the politically sensitive to the most salacious and mundane.

With the threat of war hanging over us, I asked if MPs should be more aware of the risks that surround this new communications medium? More importantly, shouldn’t the same policies and precautions that any business might use to protect itself and its staff, be available to MPs?

What concerns me is that my well-respected friend mostly considers security in terms of guns, gates and guards. He now uses the Internet almost as much as he uses the telephone and the Fax machine and yet the growing collective t…
