Swift Pick-Up

I've been having a bit of an introduction to how the police and the courts, reverse-out an IP address and resolve it to a person's identity. It's really quite fascinating.

As long as a visitor to a website(s) or a chatroom has left a trail of breadcrumbs in the shape of a date, time and IP address, dynamic or otherwise, this history can be matched up, as the first part of IP address identifies the Internet Service Provider (ISP) and the remainder, the account holder at that moment in time. Of course, it's a little more complex than this but close.

Once this information has been gleaned, then the next stage is an application for a court-order, normally uncontested by the ISP, given the recent changes in the laws governing electronic communications. The next step only takes a few minutes as the times and addresses are matched, a bit like CSI New York and with a bit of "mash-up" technology with Google Maps, you've got the location and even a satellite photo of the person's house.

Of course the police and the intelligence services can get this information in minutes. I recall an incident several years ago, when my business was receiving obscene emails into its server-driven chatroom. We involved the Metropolitan Police and waited for the sick individual to re-appear. When he did, it took about ten minutes to ascertain that he was on a computer at Kensington Town Hall (an employee) of all places and a two detectives were duly despatched to collect the suspect.

Mainframe to Mobile

Not one of us has a clue what the world will look like in five years’ time, yet we are all preparing for that future – As  computing power has become embedded in everything from our cars and our telephones to our financial markets, technological complexity has eclipsed our ability to comprehend it’s bigger picture impact on the shape of tomorrow.

Our intuition has been formed by a set of experiences and ideas about how things worked during a time when changes were incremental and somewhat predictable. In March 1953. there were only 53 kilobytes of high-speed RAM on the entire planet.

Today, more than 80 per cent of the value of FTSE 500* firms is ‘now dark matter’: the intangible secret recipe of success; the physical stuff companies own and their wages bill accounts for less than 20 per cent: a reversal of the pattern that once prevailed in the 1970s. Very soon, Everything at scale in this world will be managed by algorithms and data and there’s a need for effective platforms for ma…
A Christmas Tale

It’s pitch blackness in places along the sea wall this evening and I'm momentarily startled by a small dog with orange flashing yuletide antlers along the way. I’m the only person crazy enough to be running and I know the route well enough to negotiate it in the dark, part of my Christmas exercise regime and a good way of relieving stress.

Why stress you might ask. After all, it is Christmas Day.

True but I’ve just spent over two hours assembling the giant Playmobil ‘Pony Farm’ set when most other fathers should be asleep in front of the television.



I was warned that the Playmobil ‘Pirate Ship’ had driven some fathers to drink or suicide and now I understand why. If your eyesight isn’t perfect or if you’ve had a few drinks with your Christmas lunch then it’s a challenge best left until Boxing day but not an option if you happen to have a nine year old daughter who wants it ready to take horses by tea time.

Perhaps I should stick to technology but then, the instruc…

An Ockham of Gatwick

The 13th century theologian and philosopher, William of Ockham, who once lived in his small Surrey village, not so very far from what is today, the wide concrete expanse of Gatwick airport is a frequently referenced source of intellectual reason. His contribution to modern culture was Ockham’s Razor, which cautions us when problem solving, that “The explanation requiring the fewest assumptions is most likely to be correct;” sound advice which constantly proves to be true.

A week further-on since Britain’s second busiest airport was bought to a complete standstill by two or perhaps two hundred different drone sightings, it is perhaps time to revisit William of Ockham’s maxim, rather than be led astray by an increasingly bizarre narrative, one which has led Surrey police up several blind alleys with little or nothing in the way of measurable results.

 Exploring the possibilities with a little help in reasoning from our medieval friar, we appear to have a choice of two different account…
