What must an elk do to get served?

Dagens Nyheter reports that an elk has done a runner from a restaurant in the centre Kungsbacka, a small town south of Göteborg. The monarch of the forest had broken in — at lunchtime — thorugh a plate glass window. but the restaurant was shut. Eventually, the police turned up: the police spokesman, Stefan Jarlhage, said later that “We tried to find a vet who could help us tranquillise the elk. But before he arrived, the animal left the restaurant again. It had ben there for an hour by then, and must have got tired of waiting to be served.”

The elk has since disappeared: the police explained that they couldn’t leave the restaurant unattended with its window broken.

Good software is boring

There are two astonishing statistics in the latest OpenOffice.org newsletter.

  • The first is that nearly 25m downloads of the software have been reported. 24,800,000 — that’s a lot of 60mb downloads, and the rate is climbing steadily.
  • The second is that while millions of people have tried the software — and it’s a reasonable assumption that many are still using it — hardly anyone has hacked on it at all. Let’s be more precise. 358 people have signed the agreement that allows their changes to be redistributed. That means about 1 in 80,000 users, or 0.0015 per cent.
  • About 15,000 have signed up for the mailing lists. You wouldn’t do that unless you needed help (I’m tempted to add ‘professional help’). So, mostly, it works without too much explanation.

Put all these statistics together, and they say that software is widely attractive when it behaves as if it were commercial, and doesn’t demand interest or ideological commitment from its users. But we knew that already, so it must be true.

What kind of a machine is writing this?

One of the most enjoyable things that ever happened to me in the God business was meeting John Lucas, the philosopher who came up with one of the early arguments against AI. It is much more subtle than it’s usually given credit for, but you can find it from his web site, and here is the key paragraph, which I reproduce for its elegance:
The argument is a dialectical one. It is not a direct proof that the mind is something more than a machine, but a schema of disproof for any particular version of mechanism that may be put forward. If the mechanist maintains any specific thesis, I show that [146] a contradiction ensues. But only if. It depends on the mechanist making the first move and putting forward his claim for inspection. I do not think Benacerraf has quite taken the point. He criticizes me both for “failing to notice” that my ability to show that the Gödel sentence of a formal system is true “depends very much on how he is given that system”2 and for putting the argument in the form of a challenge in which I challenge the mechanist to produce a definite specification of the Turing machine that he claims I am.3 Benacerraf thinks that the argument by challenge reduces the argument to a mere contest of wits between me and the mechanist. But we are not trying to see who can construct the smartest machine, we are attempting to decide the mechanist’s claim that I am a machine: and however clever the mechanist is, even if he were not a mere man but Satan himself, I, or at least an idealised and immortal I, could out-Gödel it, and see to be true something it could not. Benacerraf protests that “It is conceivable that another machine could do that as well.” Of course. But that other machine was not the machine that the mechanist was claiming that I was. It is the machine which I am alleged to be that is relevant: and since I can do something that it cannot, I cannot be it. Of course it is still open for the mechanist to alter his claim and say, now, that I am that other machine which, like me, could do what the first machine could not. Only, if he says that, then I shall ask him “Which other machine?” and as soon as he has specified it, proceed to find something else which that machine cannot do and I can. I can take on all comers, provided only they come one by one in the sense of each being individually specified as being the one that it is: and therefore I can claim to have tilted at and laid low all logically possible machines. An idealised person, or mind, may not be able to do more than all logically possible machines can, between them, do: but for each logically possible machine there is something which he can do and it cannot; and therefore he cannot be the same as any logically possible machine.
Of course this entirely fails to address the Dennett/Minsky point that we are shifting coalitions of machines — against that Lucas simply says that it is indeed a different question. No one can seriuosly doubt that we’re built from machines. But something assembled in that way can be more — or less — than a single logically coherent machine, which is the kind of thing that Turing was concerned with. Something assembled in that way may turn out to be a someone; that still doesn’t make them — or me — a single machine. This point seems to me so uncontroversial that I am still surprised by the rage which Lucas’s argument arouses.

Interview technique

Playing the tape of my interview with Dan Dennett, I hear myself, and think ‘what was I thinking’; then I can hear in the following silence the other party thinking the same thing and desperately trying to discover some peg in what I have said for what it is they want to say. It’s not that I am incapable of coherent thought, but that most of the time I can only collect it on paper. There is no backspace key in real life, but I am always reaching for one — I get half way through a sentence and then realise that it should have started somewhere else if it is to go where I suddenly realise it wants to. Or I say out loud an idea — the equivalent of bashing it down before I forget — but I don’t have a mouse available to push it to its proper position three paragraphs on. No wonder the poor sod at the receiving end is mystified. The only advantage that my speech has over my writing is that it’s free of typos.

Yet all this comes about because I want the other person to talk freely. If I had a grid of questions, or if I were trying to get them to admit something, how much simpler it all would be — and how very much more difficult.

Creepy liars

I’m not a huge fan of Carl Hiaassen’s, but one of his books has a marvellous PR campaign waged against a crooked theme park. The kind of exuberant lying that both sides indulge in seems like satire, until you read this, which is an account of some of the changes made by the White House to a scientific report:
  • The final version eliminates the conclusion that healthcare disparities are “national problems.” The scientists’ draft found that “racial, ethnic, and socioeconomic disparities are national problems that affect health care at all points in the process, at all sites of care, and for all medical conditions — in fact, disparities are pervasive in our health care system.” The final version states only that “some socioeconomic, racial, ethnic, and geographic differences exist.”
  • The final version drops findings on the social costs of disparities and replaces them with a discussion of “successes.” The scientists’ draft concluded that “disparities come at a personal and societal price,” including lost productivity, needless disability, and early death. The final version drops this conclusion and replaces it with the finding that “some ‘priority populations’ do as well or better than the general population in some aspects of health care.” As an example, the executive summary highlights that “American Indians/Alaska Natives have a lower death rate from all cancers.” The executive summary does not mention that overall life expectancies for American Indians and Alaska Natives are significantly shorter than for other Americans or that their infant mortality rates are substantially higher.
  • The final version omits key examples of healthcare disparities. The scientists’ draft concluded that racial and ethnic minorities are more likely to be diagnosed with late-stage cancer, die of HIV, be subjected to physical restraints in nursing homes, and receive suboptimal cardiac care for heart attacks. The final version drops these examples. The report instead highlights milder examples of healthcare disparities, such as the finding that “Hispanics and American Indians or Alaska Natives are less likely to have their cholesterol checked.”
Especially wonderful is the bit saying that the Alaskan indians don’t get cancer as often as other people. Neither did front line soldiers in the First World War. They hardly ever died of cancer, which shows how dangerous peacetime and prosperity are to health.

But all this is only a matter of degree, not of kind, compared to the normal standards of science journalism. Governments get away with it because journalists allow it and readers want them to.

Downhill from here

In everyone’s professional life, there comes a moment that can never be surpassed. Is it happier not to notice? I don’t know. But for Roger Boyes, the Times‘s man in Germany, the choice is past. Nothing can ever live up to the intro he wrote on a story yesterday:
“A Cuban told a German court yesterday that he had been offered £3,000 to bite off the penis of a man who was later eaten by the self-confessed Cannibal of Rotenburg.”

Hot geek news

The latest developer build of OOo is slithering out: it has, I hope, integrated python scripting, along with a number of bug fixes that I don’ t understand. I have merely downloaded it, and not played with it at all, since I use the experimental version only on the laptop. On the same day a proper manual for OOo/Star Basic (about three years late) has just gone up on Sun’s web site. This is available in an absurd number of human languages. As far as I am concerned, there is only one truly hideous wart left on the program, and that’s the abysmal interface to the find/replace dialogue.

Otherwise, the program now does what a writer needs, and probably enough of what larger and more important markets need to keep thriving. Normal frivolity will be resumed as soon as possible

The ideal birthday present

For anyone worth knowing must be this. If they don’t get the joke, they are too young to be worth knowing at all.

Tragedy

There is a long interview in Ha’aretz with Benny Morris, an Israeli historian(via ). He has done more than anyone else to expose the extent to which Palestinians were deliberately driven out of Iarael in 1948, and was for many years an inspirational figure for the Left. In 1988 he was jailed for refusing to serve in the army on the occupied West Bank. His latest book has further details of massacres and rapes committed in the War of Independence by Jewish troops — not a huge number, but a lot more than we were brought up to believe — but he has come to believe they were justified as a necessary means to drive out the Palestinians.
There are circumstances in history that justify ethnic cleansing. I know that this term is completely negative in the discourse of the 21st century, but when the choice is between ethnic cleansing and genocide – the annihilation of your people – I prefer ethnic cleansing
The mistake that ben-Gurion made, Morris now says, was to draw back half way through. He should have expelled all of them.
