Stop SOPA!

Filed under: Cancon, Government, Law, Liberty, USA — Tags: , , , — Nicholas @ 13:25

Although this is a Canadian blog and SOPA is proposed legislation in the United States, it is extremely likely that Canadian websites and internet users will be directly affected by provisions of it. Michael Geist has a list of reasons why Canadians should be concerned:

First, the SOPA provisions are designed to have an extra-territorial effect that manifests itself particularly strongly in Canada. As I discussed in a column last year, SOPA treats all dot-com, dot-net, and dot-org domain as domestic domain names for U.S. law purposes. Moreover, it defines “domestic Internet protocol addresses” — the numeric strings that constitute the actual address of a website or Internet connection — as “an Internet Protocol address for which the corresponding Internet Protocol allocation entity is located within a judicial district of the United States.” Yet IP addresses are allocated by regional organizations, not national ones. The allocation entity located in the U.S. is called ARIN, the American Registry for Internet Numbers. Its territory includes the U.S., Canada, and 20 Caribbean nations. This bill treats all IP addresses in this region as domestic for U.S. law purposes. To put this is context, every Canadian Internet provider relies on ARIN for its block of IP addresses. In fact, ARIN even allocates the block of IP addresses used by federal and provincial governments. The U.S. bill would treat them all as domestic for U.S. law purposes.

Second, Canadian businesses and websites could easily find themselves targeted by SOPA. The bill grants the U.S. “in rem” jurisdiction over any website that does not have a domestic jurisdictional connection. For those sites, the U.S. grants jurisdiction over the property of the site and opens the door to court orders requiring Internet providers to block the site and Internet search engines to stop linking to it. Should a Canadian website owner wish to challenge the court order, U.S. law asserts itself in another way, since in order for an owner to file a challenge (described as a “counter notification”), the owner must first consent to the jurisdiction of the U.S. courts.

Along with thousands of other bloggers and major internet sites like Wikipedia, Quotulatiousness will be marking the anti-SOPA effort tomorrow. Unless I’ve misconfigured it, you should see a “Down Against SOPA” page the first time you visit the blog tomorrow (either on the main page or on a particular post), but then it should allow you to have normal access. I considered going “dark” as Wikipedia will be, but this seems to be a better way of registering my opposition without inconveniencing my readers too much.

To help kids stay healthier, don’t be a clean fanatic

I’ve suspected for quite a while that the “epidemic” of food allergies and other ailments among today’s children was related to the extremely hygienic conditions of modern homes (that is, kids’ immune systems were insufficiently stressed by exposure to germs, which meant higher risk of immune system over-reaction later in life). I’m not a scientist, so my suspicion was just based on less-than-statistically valid observation of my son and his friends while they were growing up — the kids with the most sterile home environments did seem more likely to have serious allergy issues come up later.

I could have been on the right track, after all:

I do wonder, however, whether we’re all becoming a bit too paranoid about germs. I include my own family in this group. Once we left the doctors’ office, for example, my wife and I encouraged our children to use a hand sanitizer. When our kids were toddlers our house had alcohol wipes and Purell vials all over the place. But is all this washing and disinfecting really necessary? Is it proactive prevention? Or overly paranoid fear?

That, at least, is the thinking behind the “hygiene hypothesis,” a school of thought first proposed by David P. Strachan in 1989, and now experiencing a resurgence that’s probably a response to society’s mania for cleanliness. Strachan’s original study sought to explain why British kids with greater numbers of older siblings had fewer incidences of hay fever, speculating that perhaps it could be the fact kids with lots of older siblings tend to be exposed to greater numbers of germs. While it was greeted with skepticism early on, Strachan’s theory has since been confirmed. In fact, in the decades since, greater exposure to germs early in life has also been associated in epidemiological studies with lower levels of asthma, some allergies and even such autoimmune diseases as type-1 diabetes and multiple sclerosis.

[. . .]

“These data support the idea that the greater diversity of microbial exposure among children who live on farms is associated with the protection from the development of asthma,” study researchers reported, speculating that microbial exposure may encourage development of immune system cells that in turn suppress the production of the sort of immune-system cells that trigger asthmatic reactions. Researchers’ next hope to determine which microbes are most responsible for preventing asthma — and that, perhaps, may lead to new therapies, such as targeted microbe exposures, for the dreaded respiratory malady.

More broadly, the study is a reminder that humans have been living and fighting off germs for tens of thousands of years. Particularly when we’re young, germs serve an important purpose for the development of the immune system. By depriving our children of exposure to germs, we may be depriving them the benefits of a process the human body has evolved over aeons, a process that helps to create healthy and allergy-free adults.

The new face of battlefield surveillance

Strategy Page discusses the Raven UAV, which has become a very popular tool with US troops in Afghanistan:

Just as the first recon aircraft a century ago changed the way armies fought, the micro-UAVs have changed the way small units of soldiers fight. A century ago the aerial observers reported to generals and their staffs. UAV video goes to platoon or company commanders, or the leader of a small Special Forces team.

The lightweight, hand launched Raven UAV can only stay airborne about an hour per sortie, but troops have found that this is enough time to do all sorts of useful work, even when there’s no fighting going on. This is most of the time.

[. . .]

The current model, the Raven B (RQ-11B), was introduced five years ago, a year after the original Raven entered service in large numbers. This UAV is inexpensive ($35,000 each) and can stay in the air for 80 minutes at a time. The Raven is battery powered (and largely silent unless flown close to the ground). It carries a color day vidcam, or a two color infrared night camera. It can also carry a laser designator. Both cameras broadcast real time video back to the operator, who controls the Raven via a handheld controller, which uses a hood to shield the display from direct sunlight (thus allowing the operator to clearly see what is down there). The Raven can go as fast as 90 kilometers an hour, but usually cruises at between 40 and 50. It can go as far as 15 kilometers from its controller, and usually flies a preprogrammed route, using GPS for navigation.

The Raven is made of Kevlar, the same material used in helmets and protective vests. On average, Raven can survive about 200 landings before it breaks something. While some Ravens have been shot down, the most common cause of loss is losing the communications link (as the aircraft flies out of range) or a software/hardware failure on the aircraft. Combat losses have been high, as nearly 20,000 have been built and most of those have been lost in training or the battlefield.

From the very beginning, the Raven changed the way troops fight. With the bird’s eye view of the battlefield, commanders can move their troops more quickly, confident that they won’t be ambushed, and often with certain knowledge of where the unseen enemy is. The big advantage with Raven is that it’s simple, reliable, and it just works. A complete system (controller, spare parts and three UAVs) costs $250,000. The UAV can be quickly taken apart and put into a backpack. It takes off by having the operator start the motor, and then throwing it. This can be done from a moving vehicle, and the Raven is a popular recon tool for convoys. It lands by coming in low and then turning the motor off. Special Forces troops like to use it at night, because the enemy can’t see it, and often can’t hear it either.

Details on the British defence cuts

Filed under: Britain, Bureaucracy, Military — Tags: , , , — Nicholas @ 09:43

The unit hardest hit by the reductions will be the Brigade of Gurkhas:

In a statement, the MoD revealed it was looking to shed 2,900 posts from the army, around 1,000 from the RAF and 300 from the Royal Navy.

The total is higher than the first round of the process last year, and there are expected to be more compulsory redundancy notices this time.

The MoD announced it was looking to shed approximately 400 Gurkhas — one in eight of the brigade. Approximately 500 infantry privates with more than six years’ service will also be axed.

The senior ranks of the army have not been spared. Eight brigadiers and 60 lieutenant colonels are expected to go.

The Royal Navy will lose five commodores and 17 captains. Nineteen Royal Marine officers will be shed, but no one from the ranks.

The RAF will lose up to 15 air commodores and 30 group captains. The MoD believes that by slowing recruiting, and not replacing those who leave, the navy and the RAF will be able to achieve the cuts they need without a “tranche 3” of redundancies. The army needs to shed almost 20,000 jobs over the next eight years and will continue to make cuts for years to come.

The media angle on the Costa Concordia wreck

Filed under: Europe, Italy, Media — Tags: , , , — Nicholas @ 09:17

Tim Black points out the most common media memes about the Costa Concordia have much more to do with snobbery and disdain than with human interest or concern about the actual causes of the shipwreck:

The sequence of events that led to the sinking of the luxury cruise liner, the Costa Concordia, is now pretty much established. But facts have not got in the way of a variety of commentators who are using the accident to parade their prejudices about too-big ships and ignorant passengers.

[. . .]

These are the tragic facts so far. What no one knows exactly is why it happened. Explanations have been mooted, of course: a power blackout affecting the ship’s steering; inaccurate navigation charts failing to show the rocks; or human error, in particular by the ship’s captain, Francesco Schettino. Yet while the exact reason for the ship straying off course remains unclear, that has not stopped another object of blame coming to the fore in some of the coverage. That is, the real, underlying reason for the Costa Concordia accident is to be sought not in the actual events of Friday evening but rather in the profit-driven, build-‘em-high cruise industry and, by association, in the sea-faring ignorance of all those who sailed aboard her.

This is why so much of the coverage seems obsessed with the size of the Costa Concordia. Over the past few days, we have been repeatedly told that cruise ships have doubled in size over the past decade. While this is true — and as the twenty-sixth-largest liner in the world, the Costa Concordia is far from the most impressive of this new breed of ships — the Concordia’s size does not actually tell us why it was three miles off course. Nor does it explain why the ship’s crew was unaware of the rock outcrop despite having navigation equipment. Yes, perhaps ship size does affect manoeuvrability, but would a smaller vessel not have suffered a similar fate that befell the Concordia? In fact, the obsession with the ship’s size sheds very little light on what happened to the Concordia on Friday evening.

What the convenient obsession with size draws upon, rather, is an antipathy towards the cruise industry, a sense that it is little more than the ocean-going equivalent of that other right-thinking person’s bête noire, Dubai. In other words, a vulgar testament to profit and sky-high consumption. So although size here is not really relevant as a cause of the Concordia’s capsizing, it appears relevant to certain commentators as a symbol of commercial hubris, of complacent materialism.
