Chatbot wears down proponents of anti-Science nonsense
Now here is an excellent use of technology.
Nigel Leck, a software developer by day, was tired of arguing with anti-science crackpots on Twitter. So, like any good programmer, he wrote a script to do it for him.
The result is the Twitter chatbot @AI_AGW. Its operation is fairly simple: Every five minutes, it searches twitter for several hundred set phrases that tend to correspond to any of the usual tired arguments about how global warming isn’t happening or humans aren’t responsible for it.
It then spits back at the twitterer who made that argument a canned response culled from a database of hundreds. The responses are matched to the argument in question — tweets about how Neptune is warming just like the earth, for example, are met with the appropriate links to scientific sources explaining why that hardly constitutes evidence that the source of global warming on earth is a warming sun.
I like this approach. It’s got lots of other applications. Now, let me see: where shall we start? There’s all that gibbering about how the bond markets will come for us if Osborne doesn’t slash public spending. And then there’s the bleating of the Irish government about how the country’s situation is “manageable”. And there’s the fantastical vapourings of the Intellectual Property lobbies…
Where the iPad comes into its own
As time has gone on, I’ve found that my iPad has a few really useful affordances. The biggest is the battery life — which means that I no longer have to cluster with other laptop users round the few available power sockets. So I now take it to every meeting where I’m likely to want to take notes. I’ve also managed to get the hang of the on-screen keyboard, so I can type reasonably quickly.
There are now tons of note-taking Apps for the device, and so far I’ve tried quite a few: Apple’s (relatively expensive) Pages App; DocsToGo; Mental Note; Dan Bricklin’s NoteTaker HD; and Simplenote. Of these, I found Simplenote to be the most useful, because it automatically syncs to all my other devices — which means that a note can be accessed from anywhere. A few weeks ago, for example, I had to give a talk at a symposium, but didn’t have time to prepare a presentation or even print a script. So in the venue car-park beforehand I jotted down some notes on my laptop using the JustNotes program (which syncs with Simplenote), and then used the synced version on my phone as an aide-memoire for the talk.
This week I was a speaker at a Cambridge symposium on “The Digital Revolution and its futures” and — as usual — took out the iPad to begin taking notes. Sitting behind me was Andrew Gruen, a Gates Scholar who is doing very interesting work on Citizen Journalism and who is also an iPad & Mac user. He tapped me on the shoulder and said “Have you heard of Soundnote?” When I looked blank, he said “Try it: it’s really cool”.
So I did. At first sight it looks like any other notetaking App. But it has one magical ingredient: it can record audio and sync the recording to the typed notes. In other words, it does much of what my Livescribe pen does, but with none of the associated gadgetry — and cost. The Livescribe pen retails at around £120, and then there’s the cost of the special notebooks (you can print your own special paper, but life’s too short for that) on top.
And the cost of Soundnote? Why £2.99. For some people — those whose work involves taking minutes of meetings, for example — it would justify the purchase of an iPad. If this isn’t a Killer App, then I don’t know what is.
There’s an informative review/description of Soundnote here.
A floral tribute…

The idea of a university: the BP version
If you’re an academic, a parent, a prospective university student in England or even — Godammit — a former Lib Dem voter, then Stefan Collini’s London Review of Books piece on Lord Browne’s attempt to re-engineer an entire higher education system is a must-read. He starts from an observation that many of us had already made — which was the curious way in which the entire subject of the report was portrayed in the media as being just about fees. Collini points out that, in a way, the fees issue is peripheral. What’s important is that the Report proposes
a far, far more fundamental change to the way universities are financed than is suggested by this concentration on income thresholds and repayment rates. Essentially, Browne is contending that we should no longer think of higher education as the provision of a public good, articulated through educational judgment and largely financed by public funds (in recent years supplemented by a relatively small fee element). Instead, we should think of it as a lightly regulated market in which consumer demand, in the form of student choice, is sovereign in determining what is offered by service providers (i.e. universities). The single most radical recommendation in the report, by quite a long way, is the almost complete withdrawal of the present annual block grant that government makes to universities to underwrite their teaching, currently around £3.9 billion. This is more than simply a ‘cut’, even a draconian one: it signals a redefinition of higher education and the retreat of the state from financial responsibility for it.
What Browne wants is
a system in which the universities are providers of services, students are the (rational) consumers of those services, and the state plays the role of the regulator. His premise is that ‘students are best placed to make the judgment about what they want to get from participating in higher education.’ His frequently repeated mantra is ‘student choice will drive up quality,’ and the measure of quality is ‘student satisfaction’. At the moment, he laments, ‘students do not have the opportunity to choose between institutions on the basis of price and value for money.’ Under his scheme, such value will be primarily judged by students in terms of ‘the employment returns from their courses’. Courses that lead to higher earnings will be able to charge higher fees.
Collini is a Professor of English, so it’s hardly surprising that he casts a beady eye on Browne’s use of the language. Consider the sentence in the report which asserts that “Students are best placed to make the judgment about what they want to get from participating in higher education.” “Looked at more closely”, writes Collini,
this statement reveals itself to be a vacuous tautology because of its reliance on the phrase “want to get”. By definition, individuals are privileged reporters on what they think they want. The sentence could only do the work the report requires of it if it said something more like: ‘Students are best placed to make the judgment about what they should get from participating in higher education.’ But this proposition is obviously false. Children may be best placed to judge what they want to get from the sweetshop, but they are not best placed to judge what they should get from their schooling. University students are, of course, no longer children, but nor are they simply rational consumers in a perfect market.
And then there is Brown’s touching faith in the market. “It is fascinating, and very revealing”, says Collini,
to see how Browne’s unreal confidence in the rationality of subjective consumer choice is matched by his lack of belief in reasoned argument and judgment. The sentence that immediately follows the vacuous one about students’ “wants” reads: “We have looked carefully at the scope to distribute funding by some objective metric of quality; but there is no robust way to do this and we doubt whether the choices of a central funding body should be put before those of students.” It is, first of all, striking that the only alternative envisaged to the random play of subjective consumer choice is an “objective metric of quality”, i.e. some purely quantitative indicator. And second, it is no less striking that instead of allowing that an informed judgment might be based on reasons, arguments and evidence, there are simply the ‘choices’ made by two groups, treated as though they are just two equivalent expressions of subjective preference. We can have the money for a national system of higher education distributed either in accordance with the tastes of 18-year-olds or in accordance with the tastes of a group of older people in London: there’s no other way to do it.
As Collini shows, the Browne report is an astonishingly vacuous document. What struck me most about it — speaking as an engineer — is the engineering mindset that it embodies. Browne owes his ascent in the university world to the patronage of Alec (now Lord) Broers, an engineer who presided over some strange developments in Cambridge university when he was its Vice-Chancellor and who often appeared to be completely mesmerised by Browne. Broers is a successful engineer but in most other respects always seemed to me to resemble Mr Magoo. His 2005 Reith Lectures (tellingly entitled “The Triumph of Technology”) were embarrassingly feeble. Most worryingly, he seemed completely blind to the significance of the humanities. And now, right on cue, comes his protege’s recommendation to cut all of the teaching grant for Arts, Humanities and Social Sciences in English universities. If the report is implemented, then only those who are rich, cultured or curious enough to shoulder the costs will study these subjects. And British society will be poorer as a result.
And, of course, everyone has been too polite to mention the fact that it was Engineer Browne who, as BP’s CEO, laid the foundations for the company’s disastrous foray into the US, and who then dug the pit for his own downfall by attempting to conceal the origins of a gay relationship. Why, one wonders, was such a booby entrusted with the fate of the British university system? For once, we cannot blame the Con-Dem coalition. The man who gave this particular clock to this particular monkey was Gordon Brown.
The Leica CL gets the Lazarus treatment
I’ve been experimenting with the Panasonic CF1 ‘micro four thirds’ camera. One of its attractions was that it came with a f 1.7 20mm ‘pancake’ lens that is optically superb. But the most interesting feature of the camera is that it takes interchangeable lenses. There are adapters, for example, for Canon, Leica and Nikkor lenses. Since I have some precious Leica glassware, it seemed like a no-brainer to try it out on this new body. And then I hit a problem: the ‘official’ Leica M adapter is eye-wateringly expensive. (Think £199.) But a trawl on Amazon revealed much cheaper third-party alternatives — like this one for £24.99. So I got one.
It works a treat — once you’ve twigged that you have to tell the GF1 menu system that the “SHOOT W/O LENS” option has to be set to “ON”. Of course, everything’s manual, but isn’t that what we fanatical photographers always say we want?
The picture (taken with an iPhone, hence grotty quality) shows the GF1 with a Zeiss 28mm Biogon which IMHO is optically as good as anything produced by Leitz. The combination of lens and Panasonic body is lovely to hold and use: it’s a perfectly balanced combination. But the strangest thing about it is how eerily reminiscent it is of a much-loved but long-abandoned Leica product — the CL.
Here’s an example of the results I got with the Biogon:
Larger version is on Flickr.
LATER: I came on this essay by a Leica owner who had sold his M8 and bought a GF1. A need for versatility was the reason he made the change. “I don’t get the same quality on any level as the Leica but I’m not missing shots and I have more options when shooting. To me, versatility and the small size are the key features of the Panasonic GF1.”
The £500m question
This morning’s Observer column.
The news that, according to the national security review at least, cyber attack comes second only to terrorism as the gravest security threat facing the nation will have come as a great surprise to most citizens. We are conscious of the annoyances of malware, viruses, worms, spam and phishing, but for most these are just minor irritations, not threats to the nation's survival.
Yet the other day we had the foreign secretary gravely intoning why, in the midst of the most savage spending cuts in living memory, it is suddenly necessary to give an extra £500m to GCHQ to protect us against nemesis in cyberspace. At the same time, in America, we see the Pentagon setting up a whole new cyber command, USCybercom, with all the usual paraphernalia and awash with funding.
What, you might ask, is going on?
There seem to be two broad answers to the question…
Reverse engineering Facebook’s ranking algorithms
Interesting experiment to see how Facebook decides which of your friends see your news feed.
The Daily Beast set out to crack the code of Facebook’s personalized news feed. Why do some friends seem to pop up constantly, while others are seldom seen? How much do the clicks of other friends in your network affect what you’re shown? Does Facebook reward some activities with undue exposure? And can you ‘stalk’ your way into a friend's news feed by obsessively viewing their page and photos?
I would like to retain ‘fart in your general direction’
Ahem. This is a transcript of a letter I discovered on a lovely site called Letters of Note. It concerns the exchanges between the team that made Monty Python and the Holy Grail and the British Board of Film Censorship.

Dear Mike,
The Censor’s representative, Tony Kerpel, came along to Friday’s screening at Twickenham and he gave us his opinion of the film’s probable certificate.
He thinks the film will be AA, but it would be possible, given some dialogue cuts, to make the film an A rating, which would increase the audience. (AA is 14 and over, and A is 5 – 14).
For an ‘A’ we would have to:
Lose as many shits as possible
Take Jesus Christ out, if possible
Lose “I fart in your general direction”
Lose “the oral sex”
Lose “oh, fuck off”
Lose “We make castanets out of your testicles”
I would like to get back to the Censor and agree to lose the shits, take the odd Jesus Christ out and lose Oh fuck off, but to retain “fart in your general direction”, “castanets of your testicles” and “oral sex” and ask him for an ‘A’ rating on that basis.
Please let me know as soon as possible your attitude to this.
Yours sincerely,
(Signed)
Mark Forstater
