How Good Is Cisco's Security Planning? In the ongoing (and somewhat silly) debate between open source advocates and proprietary software advocates, both sides like to brag that their method is better for security. Proprietary software advocates point out that by hiding the source code it's much harder for anyone to determine vulnerabilities, and allows the owner of the software to patch them quickly. Open source supporters contend the opposite is true. If the code is open, then everyone knows what's available so the natural security of the program needs to be top notch. If it's not, lots of people can contribute to a fix quickly. Well, that debate has become a bit more interesting now that everyone is scurrying around talking about how Cisco's IOS source code was swiped last week and people are wondering what sort of vulnerabilities will be turned up and exploited. Eric Raymond (whose beliefs supporting open source are well known) makes the very reasonable point that anyone developing proprietary software really ought to design it as if the source were open - in order to deal with exactly these situations. If Cisco had open sourced their IOS in the first place, the argument goes, people wouldn't be worried about vulnerabilities right now. That does leave out the other side of the story, but it is true that anyone developing software believing they can be lax on security because their source code is closed is living in a dream world. Not to say that Cisco's IOS isn't secure - but now lots of people need to worry about it.  [via Techdirt]

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…
