How to stop shoulder surfers

From New Scientist.

IN CROWDED cafes and on public transport, it's easy for people to eyeball the info on your laptop or smartphone screen. Now Sony Ericsson is patenting an answer.

Some privacy settings already let you hit a button to blank your screen when you sense a shoulder surfer is lurking. But we are often too engrossed in our work to notice such interlopers, say inventors Martin Ek and Bo Larsson.

As many netbooks and laptops now have webcams, and some smartphones have front-facing cameras, the pair have developed software that can tell when more than one face is in front of the device – and blanks the screen till they're gone (bit.ly/9fp5Gj).

They suggest certain friends could be allowed to read your screen if facial recognition software is used to exempt them from the blanking mechanism.

With one bound, the Times’s law-blogger is free!

Well, well. BabyBarista, whose witty law blog has hitherto been a must-read on the Times site, has jumped ship.

I have today withdrawn the BabyBarista Blog from The Times in reaction to their plans to hide it away behind a paywall along with their other content. Now don’t get me wrong. I have absolutely no problem with the decision to start charging. They can do what they like. But I didn’t start this blog for it to be the exclusive preserve of a limited few subscribers. I wrote it to entertain whosoever wishes to read it. Hence my decision to resign which I made with regret. I remain extremely grateful to The Times for hosting the blog for the last three years and wish them luck with their experiment. I hope very much you like the new site and also the addition of the wonderful cartoons by Hollywood animator Alex Williams who also draws the Queen’s Counsel cartoons for The Times.

Good for him.

LATER: Just noticed that Roy Greenslade has more on this. It seems that BabyBarista (aka Tim Kevan) has some reservations about the Murdoch paywall:

I think the decision will prove to be a disaster. There are so many innovative ways of making cash online and the decision to plump for an across-the-board blanket subscription over the whole of their content makes them look like a big lumbering giant, unable to cope with the diversification of the media brought about by online content, blogging, Facebook, Twitter – the list is endless.

Canute-like in their determination to stop the tide of free content and using a top down strategy which makes even the Post Office look dynamic.

Now for the next interesting question: what will Mary Beard, the Cambridge Professor of Classics, do? Her blog has hitherto been the other reason for reading the Times.

Pigeon held in India on suspicion of spying for Pakistan

No, I have not made this up. It was in the Daily Telegraph, so it must be true, mustn’t it?

Indian police are holding a pigeon under armed guard after it was caught on an alleged spying mission for arch rivals and neighbours Pakistan, according to reports in local media.

Published: 4:33PM BST 28 May 2010

The white-coloured bird was found by a local resident in India's Punjab state, which borders Pakistan, and taken to a police station 25 miles from the capital Amritsar.

The pigeon had a ring around its foot and a Pakistani telephone number and address stamped on its body in red ink.

Ramdas Jagjit Singh Chahal, a police officer, said he suspected that the pigeon had landed on Indian soil from Pakistan with a message, although no trace of a note has been found.

Officials have directed that no-one be allowed to visit the pigeon, which police say may have been on a “special mission of spying”.

The bird has been medically examined and was being kept in an air-conditioned room under police guard.

Senior officers have asked to be kept updated on the situation three times a day, according to a report from the Press Trust of India (PTI) news agency.

What motivates us?

As a co-founder and director of a technology start-up, I’ve thought a lot about what motivates staff. And I’ve been puzzled for years by a contradication that I’ve continually encountered. I’ve known lots of successful people in my time, and yet I cannot think of a single one who’s been primarily motivated by financial incentives. That’s not to say that they don’t like earning a decent salary, just that they’re not driven by money. And yet in business — and, during the New Labour years at least — in the public services also, the conventional wisdom is that financial incentives are the way to get higher performance from staff.

So you can see why I was fascinated by this cleverly-illustrated version of Daniel Pink’s RSA lecture about motivation, which is based on his book Drive: The Surprising Truth About What Motivates Us. (Full lecture here.) The essence of it is that financial incentives and penalties work well for jobs/tasks that are dull and repetitive and impose a low cognitive load on those who do them. But the minute one’s dealing with roles which are intellectually challenging, then the carrots-and-sticks approach fails.

Interesting, don’t you think? It becomes even more interesting when one sees that Neil Davidson, the co-founder of Red Gate Software, one of the most interesting and admired companies in Cambridge, decided to abandon the complex commission structure the company had developed to motivate its salesforce and replace it with a system based on (increased) flat salaries. Guess what? It works just fine, and Red Gate is taking its market by storm.

Now, here’s the really interesting bit. You may remember that whenever the issue of paying obscene bonuses to investment bankers is raised, we are solemnly informed by the directors of publicly-rescued banks that it’s essential to continue to pay said bonuses because otherwise the aforementioned wizards will go elsewhere. The clear inference is that they are entirely motivated by financial incentives, viz bonuses. But if it’s really true that financial incentives are what motivates bankers, then doesn’t it follow that the work they do is repetitive, dull and imposes a low cognitive load? And if that is indeed the case, then why don’t we just replace them with software and have done with the whole grisly business?

So does the Telegraph have a political agenda?

Silly question, I know. All papers have political agendas. But it’s interesting to note that Danny Alexander, the Lib Dem MP who has stepped in as Chief Secretary to the Treasury as replacement for Mr Laws, has now also been fingered by the Daily Telegraph on the basis of what they’ve uncovered in their precious unexpurgated CD of the Commons Fees Office’s records.

Now of course one could argue that this was just a further example of the Fourth Estate fulfilling its constitutional duty. But, if one had a nasty suspicious mind, one might wonder if it were a symptom of the proprietors’ disapproval of the coalition idea.

Google knows your MAC address

Interesting Telegraph report.

Every WiFi wireless router – the device that links most computer owners to the internet – in every home has been entered into a Google database.

The information was collected by radio aerials on their Street View cars, which have now photographed almost every home in the country.

Interesting. I wonder what would happen if I went about the streets running Macstumbler. How long would it be before Inspector Knacker began to take an interest in me? After all, he’s already obsessively interested in my street photography.

iPad redux

I’m three days into my iPad experiment (and writing The iPad Diaries as I go). Interesting to see that Jeff, with his characteristic decisiveness, has already acted.

Spot the balls

The madness begins. Lovely piece by Emine Saner in today’s Guardian. It seems that England’s spoilsport manager Fabio Capello has limited the access his players will have to their wives and girlfriends to one day after each game, with further restrictions should the team progress.

“There is a historic element that has become a kind of mythology in sport,” says Greg Whyte, professor of applied sport and exercise science at Liverpool John Moores University. “The Ancient Greeks believed that sex was detrimental in the build up to the Olympics – that it sapped energy, lowered test-osterone and reduced aggression. But research runs counter to this. There have been a few studies on sex before sport and they have shown it has no effect on performance. However, sleep quality is crucial in terms of performance and sex can enhance sleep, so therefore it may enhance performance.” Unless it’s preventing them getting any sleep.

But it seems that not all teams are facing a sex ban. Argentina’s team doctor Donato Villani was reported in the Sun (where else?) last week as saying:

“Sex is a normal part of social life and is not a problem. The disadvantages are when it is with someone who is not a stable partner or when the player should be resting.” It is very important, he notes, that “the action should not reverberate in the legs of the players.”

Quite so. I’m depressed about this. One of the most entertaining aspects of the last World Cup was the spectacle of the England Wags wandering like a cloud through a host of upmarket shopping malls.

It’s television, Eric, but not as we know it

This morning’s Observer column.

And now for something completely different: Google TV. Yes, you read that correctly: Google TV. Now I know what you’re thinking. You already have enough TV channels, most of them running Friends, Desperate Housewives or reruns of Top Gear. Why on earth would you want to watch a channel in which a T-shirted nerd with an IQ in the low thousands explains how to code an algorithm for complex linear programming in seven lines of Perl while behind him one of his more subversive colleagues is gleefully demonstrating on a whiteboard how it can be done in four?

Relax. Google TV is not a channel, it’s a platform, ie a base on which things can be built. In ordinary life, platforms are physical objects, such as the drilling rig that is causing BP such grief, but the Google guys don’t do physical. They’re geeks, so their idea of a platform is a large piece of software called an operating system. A while back, they created such a platform for mobile phones…
