Sticky: Becoming mobile-friendly

There's currently a lot of excitement among web designers about Google's announcement that they will penalise sites that don't work well on mobile devices. I've decided I need to comply with this although with less than total enthusiasm. Nearly all my pages now meet Google's new criteria (the only exception is my cycling pictures.)

The disadvantage of the change is that if you read my pages on a desktop or laptop the lines will be long (unless you adjust the width of your browser, of course). Perhaps I should have alternatives for people who are using those devices, though that would mean more complication and difficulty in maintaining both alternatives. And the variety of ways that web pages can be viewed has increased enormously, so it isn't possible to cater for all of them. Probably it's no longer a good idea to specify the width of one's lines as I did previously.

I'd be grateful for feedback on this.

Book review: An Introduction to Western Medical Acupuncture (Adrian White, Mike Cummings, Jacqueline Filshie)

This is a book about the modern medical version of acupuncture, often called Western medical acupuncture (WMA) which is widely practised by health professionals today. It is the second edition of the work (the first appeared in 2008) and is described as a companion to Medical Acupuncture: A Western Scientific Approach (Elsevier, Edinburgh, 2016), now also in its second edition. The authors are all among the foremost proponents of WMA in Britain and so are well placed to produce a book of this kind.

Its primary intended audience is health professionals who have recently completed a training programme in modern acupuncture and want to consolidate and extend their knowledge of the subject. But it will also interest more experienced practitioners, because it includes a large amount of up-to-date research evidence for acupuncture that is otherwise not easy to find gathered together in an accessible form.

Book review: Beyond Weird, by Philip Ball

Philip Ball is a science writer who was for many years an editor for physical sciences at the journal Nature. The subtitle indicates what his book is about. It is aimed at readers of books on popular science who have, Ball believes, been given a misleading impression of quantum physics, starting with the notion that it is 'weird', which Ball thinks is a cop-out. It's non-intuitive but not weird. The idea that it is


comes from our (understandably) contorted attempts to find pictures for visualizing it or stories to tell about it. Quantum physics defies intuition, but we do it an injustice by calling that circumstance 'weird'.



Quantum mechanics has the reputation of being probably the most obscure and difficult branches of science, but Ball insists that it isn't 'hard' in the way that car maintenance or learning Chinese are hard (his examples). That isn't to say that a slight readjustment of our intuitions will make everything suddenly explicable. 'Indeed, it is possible that we might never be able to say what quantum theory "means".'

Book review: Man and the Natural World, by Keith Thomas

It is becoming almost a chiché today to say that we are living through the sixth great extinction, in which an ever-increasing number of species are being driven to extinction by human activity. The writer and broadcaster David Attenborough has acquired the status of conscience of the nation by making television documentaries that bring home to a wide audience the effects of our way of life on the natural world. The latest example is his demonstration of pollution of the oceans by a deluge of plastic that is proving lethal to many of their inhabitants. The widespread media attention that all this gets today may make us think it is a modern phenomenon, but Thomas shows that its roots go back to the early modern period, when profound changes in outlook occurred.

Book review: Children of Time, by Adrian Tchaikovsky

There is an abundance of ideas in this novel but the central concept is an evolutionary one: a population of spiders acquires a technological civilisation capable of space exploration. There is no question of aliens here; the spiders belong to a species named Portia labiata, which exists on Earth today.

The world on which the spiders live has been created by terraforming carried out by humans from Earth, and is one of a number of similar projects undertaken in the remote past by the 'Old Empire'. But civil war led to the destruction of that civilisation, and Dr Avrana Kern, the scientist in charge of the spiders' world, had been left on her own for millennia. (Individuals can live for centuries in a form of artificial hibernation, although by this time she has largely uploaded herself into a computer to ensure the survival of her monitoring capacity.)

Book review: The Ends of Life: Roads to Fulfilment in Early Modern England, by Keith Thomas

'The past is a foreign country; they do things differently there.' So wrote L.P. Hartley in his novel The Go-Between, and that would be a good epigraph for Keith Thomas's scholarly but very readable study, in which he examines what the men and women of early modern England sought to make of themselves, what goals they pursued, and what were the objectives which, they believed, gave their lives meaning. Thomas uses the same metaphor as Hartley to describe his purpose in writing. [Cpntinue reading]

Making Caps Lock work as Escape in the console on OpenBSD

I installed OpenBSD on a refurbished Dell Optiflex 3020 a couple of days ago, replacing the Windows 7 it arrived with. From something I'd read on the web I thought there would be some configuring needed to get the installation to work with EFI, but in fact it went smoothly out of the box.

A couple of minor things to say about the console.

1. I wanted Caps Lock to give me Escape in the console. The OpenBSD FAQ tells you how to do this with wsconsctl but I got a message saying that Caps_Lock was not a keysym. I found a fix for this at reddit (thanks, Kernigh).

2. Still on the console, I get messages about the mouse, saying _"wsmouse0 detached" . This seems to be a known bug but I don't have a satisfactory fix. I can stop the messages appearing by installing the mouse on the console but then it doesn't work in X. It's annoying but not serious since I normally start X immediatejy after logging in.

Probably the easiest solution is simply to unplug the mouse when you're in the console.

Book review: Religion and the Decline of Magic, by Keith Thomas

Keith Thomas tells us that this book began as an attempt to make sense of why some now outmoded belief systems, which he terms collectively magical, were current in sixteenth and seventeenth century England. As he wrote he found that there was a close relationship between these beliefs and the religious ideas of the period; sometimes the two seemed to be closely connected, at others they were in conflict. He therefore enlarged the scope of his study to include an examination of these interactions. Inevitably the result was a very long book, even though he deliberately confined the discussion to England, with only brief glances at Wales; he made no attempt to include Scotland or Ireland, let alone continental Europe.

This is probably the most comprehensive and widely cited study of these subjects to have appeared in the last half-century. Although it is a scholarly work, it scores highly for readability. [Continue reading]

Breast screening error: disaster or blessing in disguise?

The NHS computer error that has resulted in some 450,000 women aged around 70 not having received an appointment for a final breast screen is obviously, and understandably, deeply worrying for the women concerned. Predictably, the media have headlined the estimate that up to 270 of them may have developed cancers that are more advanced and difficult to treat than they would have been if diagnosed earlier. But this depends on a number of assumptions. Leaving aside the fact that this is the upper limit of an estimated 135-270 range (compare the "up to" speeds quoted by ISPs - how many customers achieve them?), the situation, as usual, is more complicated than the headlines imply.

New Scientlst has a good discussion of the question (Why breast screening error stories are getting death stats wrong). This article makes the important point that, for some women, the failure to notify them may have done them a favour. The current NHS estimate is that, for every 200 women in the 50-70 age range screened, one will be spared an early death but three will have unnecessary treatment for cancers that would not have been a problem in their lifetime.


... it means that up to 800 women may have been saved from harm by not sending them their final screening appointment letter, as they avoided possible reduction in their life expectancy through unnecessary treatment.


The New Scientist article makes the important point that the women who received unnecessary treatment would never know this and would presumably be forever grateful, believing that their lives had been saved by the 'harrowing treatment process'. So this is an 'invisible' harm that is difficult to quantify.

Book review: The Mind Is Flat, by Nick Chater

Sigmund Freud did not invent the notion of the unconscious—in one form or another it goes back to antiquity—but he undoubtedly popularised it. Thanks largely to him, many people today think of their minds in terms of the iceberg metaphor, which implies that much of what goes on in our minds is largely or completely unknown to us. The idea of the unconscious is deeply infused in art, literature, and many other aspects of our life; in fact, it is so widespread that it is practically impossible to escape.

But why has it remained so popular? Probably because it corresponds with how we think of ourselves intuitively. (At least, this is true for Westerners; whether the idea is so deeply ingrained in other cultures I'm not sure.) And yet some psychologists and philosophers have rejected the notion of an unconscious mind. This where Chater stands, although, as he tells us, he came to this view only after a long struggle.
