Position of the human operator in the Mechanical Turk

The Register has built up a picture of the company that makes believing SpinVox’s revised claims extremely difficult. Sources suggest SpinVox, a privately held company, is employing a far larger number of transcribers than it publicly states, even today. These sources also point to extreme difficulties in maintaining its operations as the company scaled, winning new carrier contracts in new markets. And an investigation into the company’s much-vaunted intellectual property holdings indicates that it holds no machine translation patents.

The humans can make themselves felt. In one case, unpaid staff in Pakistan took over the centre and began broadcasting “distress” text messages to SpinVox subscribers in North America.

By insisting that its operation relies primarily on machines, rather than human manpower, SpinVox avoids security issues and can maintain a much higher corporate valuation. Mobile carriers are aware that ‘Mechanical Turk’ (named after the chess-playing Victorian automaton that concealed a human operator) transcription has high costs, as Vodafone found out with its human-assisted service.

To the Moon – with extreme engineering

Wednesday, July 22nd, 2009

Lunar Orbiter

Apollo space program as a triumph of power and industrial might. The superpowers’ space programs were, of course, political and chauvinistic, designed to showcase national wealth. But there’s a better way of looking at the program, Dennis Wingo reminded me recently. Masses of money helped put man on the Moon of course, but the Moon program is really a tale of engineering improvisation and human organisation.

Space expert and entrepreneur Dennis Wingo put the first webserver – an Apple Mac – in orbit, for just $7m, and has helped piece together a lot of historical material that NASA didn’t appreciate at the time – and forgot about, or wiped. There is one piece of kit in particular that encapsulates two stories: NASA’s negligence, and the quite amazing improvisation of the engineers. It’s the Lunar Orbiter, which mapped the moon’s surface prior to manned descent. Wingo painstakingly recovered and restored much of the imagery it took.

To give us an idea of how much Apollo owed to seat-of-the-pants ingenuity, it’s worth remembering that the story of the Orbiter begins in 1961 – the year of the first human orbit of the Earth by Yuri Gagarin. The space pioneers were seeing a high death rate from test subjects – dogs (the USSR) and chimps (the USA), the latter proving to be a duff move – the chimps panicked in the claustrophobic conditions.

The US program lagged far behind the Soviets’, and NASA’s early attempts to keep up had become a national joke. The Ranger had been the first project to photograph the moon, with the modest ambition of crashing a probe onto the surface. But of the first six Rangers, two failed to leave the Earth’s orbit, one failed en route, two missed the Moon completely, and although the sixth reached the target, its cameras failed.

Yet by 1964, much of the technology that eventually put man on the Moon had been already designed and built. The colossal Apollo expenditures were on the physical implementation of the program, including the many test flights. By 1965, the Apollo Lunar Excursion Module (LEM) was already being prepared as a long-term shelter and accommodation unit. And as Wingo points out, it was really down to 400 engineers – a fraction of what Google devotes to inserting advertisements into web pages – being given the freedom to put Heath Robinson designs into practice.

The Lunar Orbiter astonishes even today. It had to take pictures, scan and develop the film on board, and broadcast it successfully back to earth. Naturally, the orbiter had to provide its own power, orient itself without intervention from ground control, and maintain precise temperature conditions and air pressure for the film processing, and protect itself from solar radiation and cosmic rays – all within severe size and weight constraints. This was far beyond the capabilities of the newest spy satellites, which back then returned the film to earth in a canister, retrieved by a specially kitted-out plane. The Orbiter challenge was the Apollo challenge in miniature.

The Tragedy of the Creative Commons

Thursday, July 16th, 2009

The Creative Commons initiative fulfilled a major ambition last week – but it’s taken only days for the dream to turn to crap.

Google granted the wish by integrating the ability to search images based on rights licences into Google Image Search. Yahoo! Image Search has had a separate image search facility for years, but Google integrated the feature into its main index.

The idea of making the licences machine-readable was a long-standing desire of the project, and lauded as a clever one. It was intended to automate the business of negotiating permissions for using material, so machine would instead negotiate with machine, in a kind of cybernetic utopia. Alas, it hasn’t quite worked out.

As Daryl Lang at professional photography website PDN writes, the search engine is now choked with copyright images that have been incorrectly labelled with Creative Commons licences. These include world-famous images by photographers including Bert Stern and Steve McCurry. As a result, the search feature is all but useless.

Since there’s no guarantee that the licence really allows you to use the photo as claimed, then the publisher (amateur or professional) must still perform the due diligence they had to anyway. So it’s safer (and quicker) not to use it at all.

What’s gone wrong, as Lang explains, is the old engineering principle of GIGO, or Garbage In, Garbage Out:

“The system relies on Internet users to properly identify the status of the images they publish, Unfortunately, many don’t… Many Flickr users still don’t understand the concept of a Creative Commons licence, or don’t care.

“It’s time consuming to put a different label on every image [in their collection], and there are no checks in place [our emphasis] to hold users accountable for unauthorized copying or incorrect licensing labels.”

So Google won’t take responsibility for the accuracy of the licensing metadata, and Creative Commons, as a small private internet quango, says it can’t afford to. (The disclaimer on the website is simple: go find yourself a lawyer.)

Just as we predicted, in fact: the filtering is less than perfect, and it’s a lip-service to creators. Now, why did it have to fail?

The bogus logic of 'sustainability'

NEF co-author Saamah Abadallah

Did you know people in Haiti, Burma and Armenia are all better off than in Britain? And the Congo is happier than the USA? That’s what the London think-tank New Economic Foundation reckons in its second “Happy Planet” rankings. But even NEF admits that its “happiness” rating or HPI doesn’t really measure human happiness, and that it’s sacrificing truthiness for the publicity its reports can generate.

Like the notorious Carbon Calculator, the Happy Planet Index is an advocacy tool for limiting, rather than promoting, human health and happiness, and it too is based on the idea of an ecological “footprint”. This Neo-Malthusian concept was developed by population-control advocate William Rees, a professor at British Columbia University, and his splendidly-named pupil Mathis Wackernagel. The latter has since turned it into a successful consultancy business.

NEF uses older surveys where people expressed happiness, multiplies it by life expectancy, and divides it by the “footprint”. Factors such as crime, freedom, or infant mortality rates are not considered.

So not surprisingly, given this skew, the “Happiness Index” produces some very odd results. The last survey was topped by the Republic of Vanautu. The south sea nation has a population of just over 200,000 and an infant mortality rate of one in 20 – about 10 times that of the UK.

The authors urge industrialised economies urgently need to become more like the underdeveloped. In human terms, that would mean over 300,000 unnecessary child deaths in the UK each year. Such is the price of happiness, NEF argues.

NEF also frowns on India and China for improving the material welfare of their people. Accompanying the report is a spreadsheet which hindcasts the NEF “happiness” figure retrospectively. It tells us that since 1990, China and India’s “HPI rating” has fallen.

In the latest survey Costa Rica tops the poll, and Vanautu has dropped out completely. Jamaica ranks third, Columbia is at six, Bhutan (with 74 deaths per 1,000 live births) and Laos (89 per 1,000) is in the Top 20 – far higher than any OECD country.

It’s too bizarre even for some anti-capitalist environmentalists. Writing on his blog, the activist Derek Wall, author of Babylon and Beyond: The Economics of Anti-capitalist, Anti-globalist and Radical Green Movements observes that:

“Colombia comes in at number six on the index out of 143 countries… yet death squads commonly clear peasants from the land for biofuels. Doesn’t sound that good a place to me.”

“But maybe I am just one of those old fashioned left greens who worries about little things like human rights and the environment?”

Meet the Carbon Cult, Derek.

Google's vanity OS is Microsoft's dream

Wednesday, July 8th, 2009

No one will be happier than Microsoft about Google’s vanity venture to market computers with a Google-brand OS. It gives us the illusion of competition without seriously troubling either business, although both will obligingly huff and puff about how serious they are about this new, phoney OS war. Since both of these giants are permanently in trouble with antitrust regulators – they’re at different stages of IBM-style thirty years legal epics – that’s just the ticket for them both.

Google’s failure to dent the Microsoft monopoly will simply notch up another failure for Linux (whose fans are quite happy to work for The Man, as long as it’s not the Man from Redmond) – and it’ll do nothing for consumers. How so? Because the computing problems we’ll have tomorrow will still be the same ones we have today.

BBC pulling back from the DAByss?

Tuesday, July 7th, 2009

Simply because Tim Davie, the BBC’s new radio chief, has a background in advertising and marketing, that isn’t a reason to assume everything he says is a lie. It’s more charitable to say he’s well practiced in the dark acts of spinning, having learnt the trade at Pepsi and Proctor and Gamble. And so you might want to take the explanation he offered on DAB strategy last week with a large dose of organic salt.

For the first time, a top BBC executive admitted that DAB radio isn’t inevitable. The Director of BBC Audio and Music told Radio 4′s Feedback programme that “since I have arrived at the BBC, I certainly haven’t seen it as inevitable that we move to DAB.”

Davie continued:

“We do believe that, if radio doesn’t have a digital broadcast platform, it will be disadvantaged. I’m pretty convinced of that logic. What I’m not saying is that we have to move at 2015 if we haven’t delivered the thresholds – the right levels of listening to digital radio and to DAB. I don’t think we are on a course that is unstoppable to 2015, although we are pretty committed to a DAB switchover over time.”

Davie was responding to a deluge of negative responses unleashed by Carter’s Digital Britain report. The report, the nation’s Media Correspondents told us, would order analog radio to be switched off in 2015. Incorrectly, as it turned out. Emboldened by this, it was suddenly open season on DAB. The Tories have sniffed a vote winner, although shadow culture secretary Jeremy Hunt shows the same reluctance to grasp the underlying problems.

Radio 4′s Today programme sent its radio car to the remote location of er, BBC Television Centre, and discovered DAB reception “is more irritating than Norman Collier’s broken mic routine”. That is, if they could get it at all. Back in the studio, former TalkSport owner Kelvin McKenzie listed more DAB closures and concluded: “There are no advertisers out there, no listeners out there. DAB is a technology whose day is done.”

Davie was merely trying to defang the backlash. Listeners don’t like to feel bullied, and especially not bullied onto a technology that is perceived to offer only disadvantages. No one talks about the much-vaunted crystal clear reception any more, or choice, or whizzy new features.

“What we might be seeing is the opening salvo of an action folder marked ‘Possible DAB Downgrade/Exit Strategy’”, mused the radio analyst Grant Goddard. “The nuclear button might never have to be pressed, but it’s always useful to know where the exit doors are and how you are going to reach them, however little you might want to think about the DAB plane going down in flames.”

I’m not so sure.

Carter’s report failed radio by ducking two serious areas. DAB’s problems are both technological and financial, and the two are interlinked. More modern codecs offered by DMB (the DAB technologists’ preferred route) or DVB-H could cut the transmission costs, lead to cheaper sets, and give us better and more complete reception. This required something stronger than what Carter proposed – an airy desire that sets should be forward compatible somehow.

As for the financial issues which beset commercial radio, it’s hard to see how anything short of a compulsory nationalisation of Arqiva and chopping up the spectrum could help. (Arqiva is where the BBC and the Independent Broadcasting Authority’s transmission facilities, along with DTELs, the Home Office’s radio network for defence and emergency services, have ended up).

The BBC doesn’t want half of its audience to disappear overnight, either (one of the two switchover criteria is 50 per cent of listeners), so here we see Davie steering it away from backing any kind of commitment. But nor does the BBC want a fragmented world where the audience wanders off to discover more engaging material, as they have since the very beginning of radio. That’s what Davie means by “a digital broadcast platform” – he means one single, nationwide, one-to-many broadcast standard, with presets in all the receivers. The sheep must not stray from the fold.

So we’re muddling along as before, without the carriage costs being addressed, and without a firm roadmap for DAB’s successors. One thought ought to keep radio executives awake at night. By 2015, IP networks will be fully capable of IPv6 multicast, as we’ll be well into 4G (LTE) deployment by then. If half of the terrestrial radio is audience is disenfranchised overnight, the mobile operators will only be too happy to offer them – and advertisers – a home from home.
