England: land of history … and archaic laws that still can bite

Filed under: Britain, History, Law, Religion — Tags: , — Nicholas @ 10:50

Do you live in England? Do you live near an old church? Brace yourself for possible bills to repair that lovely old pile of crumbling stone:

Because of the way land was carved after the dissolution of the monasteries under Henry VIII, the owners of many houses sited near historic churches have a legal obligation to contribute to repairs.

People living in more than 5,000 parishes in England are subject to the historic “chancel repair liabilities”, which affect properties built on former monastic land.

Most take out a form of insurance against the liability but many so-called “lay rectors” are entirely unaware of the obligation as it is rarely enforced.

But now, after an attempt by the last Government to tidy up the law in the wake of a high profile court case, parishes have been ordered to trawl through land records dating back hundreds of years to clarify exactly who is liable.

A 10-year legal deadline imposed by the last Government is due to expire next year and local parish bodies have been warned they could be legally responsible if they fail to comply.

Charles Stross: Where Moore’s Law and Koomey’s Law interact

On his blog, Charles Stross explores the long-term implications of Moore’s Law (the doubling of computer circuits every two years) and Koomey’s Law (the energy efficiency of computers doubles every eighteen months):

A couple of basic physical rules underly the dizzying progress in electronics that we have seen over the past fifty years. Moore’s Law, attributed to Intel co-founder Gordon Moore, postulates that the number of transistors that can be placed on an integrated circuit of constant size doubles approximately every two years. Originally coined in 1965, Moore’s law has run more or less constantly ever since. It can’t continue indefinitely, if only because we’re getting close to the atomic scale; a silicon atom has a Van der Waals radius of around 200 picometres, and to build circuits that mediate electron transport we need discrete atomic-scale structures. It is not obvious that we can build electronics (or other molecular structures) with a resolution below one nanometre. So it’s possible that Moore’s law will expire within another decade.

Having said that, predictions of the imminent demise of Moore’s Law within a decade go back to the 1970s. And if we can’t increase the two-dimensional structure count on an integrated circuit, we may still be able to increase the number of structures by building vertically.

A newer, and more interesting formulation than mere circuit count is Koomey’s Law, proposed by Jonathan Koomey at Stanford University: that the energy efficiency of computers doubles every 18 months.

This efficiency improvement has held true for a long time; today’s high-end microprocessors require far less power per instruction than those of a decade ago, much less two or three decades ago. A regular ARM-powered smartphone, such as an iPhone 4S, is some 12-13 orders of magnitude more powerful as a computing device than a late 1970s-vintage Cray 1 supercomputer, but consumes milliwatts of power for computing (rather than radio) operations, rather than the 115 kilowatts of the Cray.

Taking them together, what do these two laws imply about the not-too-distant future?

US military faces recruiting nightmare

Strategy Page outlines the most recent major problem the US military is facing: the bloat of potential recruits (not in numbers, but in individual mass). While the number of new recruits needed is declining, the pool of potential recruits to draw from has been declining even faster:

The problem is that Americans have, in the last two decades, become very fat and out-of-shape. There are 32 million male Americans of prime military age (17-24). But because of bad lifestyle choices, only 13 percent of them (4.2 million) are physically eligible for service. Each year, the armed forces have to recruit 150,000 new troops. The military is allowed to waive some physical or mental standards, and this means that only about 20 percent of those 32 million potential recruits qualify. Each year, recruiters have to convince about two percent of those eligible that they should join up. It’s a tough job, made worse by a generation that eats too much, exercises too little and doesn’t pay enough attention in school. You not only have to be physically fit enough to join, you also have to be smart enough and have no criminal record.

The enormous growth in computer entertainment, and subsequent massive reduction in exercise teenage boys get is the major reason for the body fat percentage crisis. As a result, one of the biggest problems American military recruiters have is unfit young Americans trying to enlist. Some 57 percent of potential recruits are not eligible because they do not score high enough on the aptitude test the military uses to see if people have enough education and mental skills to handle military life. Many of those who score too low do so because they did not do well at school. A lot of these folks have high IQs, but low motivation. Most of the remainder are not eligible for physical reasons. But get this; the most common physical disqualifier is being overweight. Nearly a third of the people of military age are considered obese. Many of these big folks are eager to join, and are told how much weight they have to lose before they can enlist. Few return light enough to sign up.

Computer gaming and other forms of indoor entertainment certainly bear some of the blame for the obesity problem, but other issues should also be included: helicopter parents who don’t dare let their kids go outside to play without full-time parental supervision, schools that have reduced or eliminated physical education for budget or liability reasons, and the huge increase in availability of low-priced, high-calorie fast foods.

The real reason behind the war on the humble plastic bag

Filed under: Environment, Liberty, Media, Politics — Tags: , , , , — Nicholas @ 08:54

Tom Bailey explains that the reasons we’ve been given for the renewed attacks on plastic bags are not the real reason for the ongoing struggle:

Individually, a plastic bag weighs about eight grams. In total, we use about 10 billion of them a year, adding up to around 80,000 tonnes of plastic bags. A large number, perhaps, but not when compared with total municipal waste. The total amount of household waste produced each year is 29.6million tonnes. This means that plastic bags make up a mere 0.27 per cent of what we all throw away every year. This percentage would become even smaller if we were to include commercial and industrial waste in our calculations.

The total amount of oil used to produce plastic bags is also exaggerated, considering that most plastic bags are made using naphtha, a part of crude oil that isn’t used for much else and would probably be burnt away otherwise.

So what’s going on here? Why the panic about a simple little bag? The assault on plastic bags is really an assault on consumerism. There is a prevailing view among the green and mighty that consumerism is bad. It is portrayed as being a modern-day vice, devoid of meaning, something which atomises society, corrupting us through crude materialism and distracting us from more important issues.

Plastic bags are an outward reflection of the ease with which people can buy goods and take them home. People now have the disposable income to enter a shop unexpectedly and buy a load of stuff, and plastic bags mean they can rest assured they they will have the means to carry their purchases. How often do people returning home from work decide, on a whim, to make a quick stop at Tesco Express to buy a few items of food? How frequently, perhaps on a journey past Oxford Street, are we drawn into a sale by a piece of attractive clobber? Such nonchalant consumption would be made more difficult, perhaps more expensive, without shops’ provision of handy, free plastic bags.

I guess I must be a puppet of “Big Plastic”, as I’ve posted about this issue a few times already.
