I hate hovercards

You know the deal: some website decides that it would be super slick to show a preview of linked pages when you hover your mouse over a link, or a preview of someone’s profile when you hover over their Gravatar.

The trouble is, it is obtrusive and distracting. Moving a mouse over a website shouldn’t cause dramatic new things to happen. When they do, they break concentration and cause frustration.

It is acceptable to have menus that enlarge when you hover a mouse over them. Mouseover text for images is also perfectly fine, since it takes a moment to appear and is thus effectively requested rather than imposed. By contrast, website elements that pop out of nowhere just because a cursor crossed something are bad form in the same way as universally despised pop-up ads.

Thankfully, many such unwanted features are killed by AdBlock and NoScript.

WordPress.com offsite redirects

There are too many pieces of software and web services that rely on a deliberate lack of interoperability to lock in users and boost profits. While it may be better for companies when people are forced to use operating X, software Y, and website Z, it is usually better for users if they can use any combination that suits their purposes. Apple is particularly notorious, when it comes to locking things down and sabotaging their own products.

One welcome exception is the new link forwarding service on WordPress.com. One early choice faced by bloggers is whether to use free hosting on a site like WordPress.com or whether to get their own hosting account. The former is cheaper and easier, while the latter allows many more possibilities. Now, users on WordPress.com who decide that they want the added power that comes with private hosting can move in a way that preserves all their old URLs and avoids exposing visitors to error 404 pages.

The service costs $15 per year and uses 301 permanent redirects. That means Google and company will figure out the new addresses for your content, avoiding the need to keep paying WordPress indefinitely.

A Wizard of Earthsea

Ursula Le Guin’s slim novel tells the story of the early life of Ged: a wizard whose hubris leads him to over-extend his powers, and who must undertake an agonizing quest to address the consequences:

There was no need to hunt the thing down, to track it, nor would its flight avail it. When they had come to the time and place for their last meeting, they would meet.

But until that time, and elsewhere than that place, there would never be any rest or peace for Ged, day or night, on the earth or sea. He knew now, and the knowledge was hard, that his task had never been to undo what he had done, but to finish what he had begun.

It’s a classic parable and well crafted. It’s actually the first book of Le Guin’s I have read, so I feel like I partly corrected an oversight in my general exposure to speculative fiction.

The book is successful at evoking the sense of a fully-formed world, despite not having to give over much time or space to elaborate exposition. That, combined with the consistency and convincingness of the tone, makes the book seem immersive and meaningful.

Canada doesn’t deserve a UN Security Council seat

At the moment, Canada is competing for one of the ten non-permanent seats in the United Nations Security Council – the principal international body charged with the maintenance of international peace and security. Canada thinks of itself as an internationalist country that has committed itself to peacekeeping and other forms of international assistance. Unfortunately, Canada is also doing virtually everything in its power to worsen the most pressing medium-term threat to international security, namely climate change.

At the moment, the United Nations process designed to find a successor to the Kyoto Protocol is going nowhere. While that situation has many causes, one of the most important has been the unwillingness of developed states to make real commitments and take meaningful domestic action. For its part, Canada has adopted targets that would be better than nothing, but which are neither fair now adequate. In order for the world to avoid dangerous climate change, other countries would need to pick up the slack created by Canada’s lack of ambition. Even worse, Canada has no credible plan to meet those targets, and has taken no serious domestic action on climate change.

Right now, Canada is flirting with some of the most dangerous energy options out there. These include unconventional oil and gas, including the oil sands and shale gas, as well as fossil fuel reserves in formerly inaccessible places like the Arctic. Chasing those fossil fuels is foolishness. It commits us to perpetuating an energy system that profoundly threatens future generations, and redirects resources from the task of building a sustainable basis for our society.

As long as Canada continues to behave with such reckless disregard for those outside its borders, including those who are not yet born, it doesn’t deserve the prestige associated with a Security Council seat. To be sure, some of Canada’s international actions have been and are praiseworthy, but that doesn’t counterbalance the way in which Canada is helping to commit the world to a colossal blunder. Ultimately, it may require Canada becoming an international pariah before our government will stand up to the oil and gas sector. Hopefully, it won’t come to that. If Canada loses its bid for this seat on the basis of domestic and international disapproval of our environmental record, perhaps it will be a much-needed signal that our recent conduct has been unacceptable.

[Update: 12 October 2010] Canada’s bid was unsuccessful. Hopefully, the embarassment will encourage Canada to play a more constructive role in future climate change negotiations.

Colds and the immune system

The New York Times recently printed a timely op-ed about the common cold, arguing that the remedies people take for them are generally useless and that the disease itself is misunderstood:

Here was a new insight in cold science: the symptoms are caused not by the virus but by its host — by the body’s inflammatory response. Chemical agents manufactured by our immune system inflame our cells and tissues, causing our nose to run and our throat to swell. The enemy is us.

Indeed, it’s possible to create the full storm of cold symptoms with no cold virus at all, but only a potent cocktail of the so-called inflammatory mediators that the body makes itself — among them, cytokines, kinins, prostaglandins and interleukins, powerful little chemical messengers that cause the blood vessels in the nose to dilate and leak, stimulate the secretion of mucus, activate sneeze and cough reflexes and set off pain in our nerve fibers.

So susceptibility to cold symptoms is not a sign of a weakened immune system, but quite the opposite. And if you’re looking to quell those symptoms, strengthening your immune system may be counterproductive. It could aggravate the symptoms by amplifying the very inflammatory agents that cause them.

I always find it a bit weird that whole industries exist to sell products that are either useless or actively harmful. While that is understandable enough when it comes to harmful-but-fun products like alcohol and tobacco, it is more ethically dubious in the case of things like cold medications that do not stand up to scientific scrutiny. Quite probably, they should bear warning labels from some kind of consumer protection agency saying: “As far as science has been able to establish, this product is useless for reducing the duration of colds.”

Democracies and the wisdom of crowds

There are no perfect democratic systems; all those that have ever existed, that exist now, and that will exist have flaws.

In systems like Canada’s, voters choose between individual candidates. And yet, the platforms and leadership of parties are usually much more important for the direction of policy-making than the identity of individual Members of Parliament. By contrast, there are countries with systems of proportional representation in which the importance given to individuals is too little. That leaves voters without a direct mechanism for electing especially wise or capable people, and can diminish the level of awareness assemblies have to local issues.

On many other dimensions, the structure and character of democratic governments differ – whether the issue is the lobbying system, electoral law, federal versus central states, or something else. Each particular set of circumstances aids some groups (think of how Canada’s first-past-the-post system helps the Bloc Quebecois) while harming others (think of the Greens).

In the end, it isn’t possible for every country to establish a government that incorporates every desirable feature. Quite simply, some of them directly contradict others. What could be possible, however, is to exploit the wisdom of crowds. If we recognize that our system of government has deficiencies that manifest themselves in problematic policies, keeping an eye on policy development in other jurisdictions can serve as a bit of a counter to that. This already happens, for example, as when people turn to Scandinavia when discussing drug or childcare policies.

Taking a step further, it is possible for the political decisions in other democratic places to directly affect the situation in Canada. One major mechanism for this is when courts apply foreign precedents, particularly when dealing with new areas of law, or issues in which societal expectations are changing. Every time a judge presented with a case on gay rights or intellectual property gives consideration to what is happening in Europe or New Zealand or India, they are taking advantage of the diversity in policies that accompanies the diversity in forms of democratic government.

The ultimate example is something like the European Union, which actually incorporates 27 democratic governments and has decision-making power of its own. One of the reasons why it is such an exciting experiment is because of the potential it was for allowing the flaws of each constituent state to be partially counterbalanced by the sensible overall character of the consensus.

Of course, all this is anathema to the kind of old school patriots who are fearful of foreign precedents in domestic courts and cling as much as possible to the original words and meanings of founding documents. That is not an entirely irrational attitude. It is certainly possible that following the wisdom of crowds will produce a worse outcome than going it alone will. Overall, however, I think that a greater degree of international policy coordination is likely to be beneficial. Partly, that is a consequence of the extreme interconnectedness and interdependence of human beings today. The happenings in one political jurisdiction have never been more relevant and important to the inhabitants of all others. That – along with the potential to smooth the rough edges of our domestic political systems – is a major reason for making our sovereignties a bit more porous.

Debating the oil sands

On November 13th, Green Party leader Elizabeth May will be debating Ezra Levant, the author of Ethical Oil: The Case for Canada’s Oil Sands. The event is taking place at the Library and Archives Canada on November 13th.

2:30pm – showing of the film “Mine Your Own Business

4:00pm – approximate debate start time

It should be interesting. I may show up myself to ask Ms. Levant about the oil sands, climate change, and the importance of cumulative emissions.

I found out about the event via Apt 613.

A geeky mystery from the new GG

Last week, I heard but did not see the CF18 jets that did a flyover of Ottawa to commemorate David Johnston becoming Canada’s new Governor General. While I believe that the monarchy is a dated institution that ought to be scrapped, I do appreciate one modern touch Mr. Johnston brought to his office, in the form of a geeky mystery built into his coat of arms. Along the bottom is a palindromic binary sequence: 110010111001001010100100111010011.

Converted to decinal representation, that is: 6830770643. In hexadecimal, it is: 1972549d3.

The decimal is pretty close to the current estimated world population. The number is also a Sophie Germain prime.

The CBC Inside Politics blog has been puzzling over the sequence, without success. So has Slashdot. Whatever the meaning of the string is, it seems to be better concealed than the MD5 hash in the emblem of the United States Cyber Command.

Any ideas?

DDT and evolution

Naomi Oreskes’ book about climate change deniers makes some interesting points about the pesticide DDT. Apparently, there has been a kind of campaign recently to challenge the history of the substance and its ban, with some anti-regulation groups claiming the regulation of DDT was unneccessary and caused many human deaths. They argue that if DDT use had not been regulated, malaria could have been eradicated.

Oreskes seems to rebut this argument convincingly. Critically, she points out how DDT had been stripped of its effectiveness through over-use, particularly in agriculture. She makes the point that the consequences of different sorts of DDT use for the genetics of the mosquito population can be very different. Spraying indoors exposes only a small minority of mosquitoes to the chemical, leaving most of the population isolated from it. As a consequence, there is only a small advantage for those mosquitoes that are more resistant to the poison. By contrast, widescale agricultural spraying exposes whole populations of mosquitoes to the toxin. Those who are a bit resistant to it have a huge advantage, and soon come to dominate the population. Over time, the indiscriminate use of DDT breeds mosquitoes who are troubled less and less by the toxin.

Oreskes documents how the banning of DDT took place only after its effectiveness was lost, as well as how the environmental and human health effects of the substance were sufficiently worrisome to justify the ban. She argues that the recent attempt to change the historical narrative is not about DDT itself – which nobody is seeking to reintroduce. Rather, it is intended to foster and enlarge a general sense that taking precautions to protect human health and the environment is unjustified, and that science that supports the regulation of industry and individual behaviour is ‘junk’.

A related situation that I have written about before is the abuse of antibiotics in the livestock industry. Just as the agricultural use of DDT provided ideal circumstances for insects to evolve resistance, today’s factory farms may as well have been custom designed to render our antibiotics ineffective. Crowding huge numbers of unhealthy animals close together, flooding them with chemicals to make them grow as quickly as possible, feeding them unnatural diets, and then using antibiotics to try and keep them from dying too early, is a string of compounding errors. Not only does it demonstrate considerable disregard for the welfare of the animals in question, but it demonstrates a lack of foresight when it comes to maintaining the effectiveness of our drugs and the relative manageability of the bacteria out there.

Of course, the political system tends to favour the small group of farmers that benefits from the status quo and which would suffer significantly from a change in policy, rather than the great majority of people who are incrementally harmed by the emergence of ever-more-dangerous superbugs, and the dilution of the effectiveness of the relatively small class of chemicals capable of safely killing bacteria inside human beings, without causing undue harm to the person.

Zero History

Zero History is the third novel in Vancouver author William Gibson’s latest trilogy of science fiction set in the present. It is the sequel to Spook Country, which came out in 2007.

Like all of his work, it is clever and well written. This trilogy succeeds in meshing together the trends and technologies of the past with those of the near-future. It also generates some intriguing characters – in this case, the recovering benzodiazapene addict Milgrim is the most interesting. Unfortunately – as is common in science fiction – Gibson does a better job of setting up a mystery than of resolving it. That and a few forgettable, interchangeable characters constitutes the biggest limitation of the work. Once again, Gibson hasn’t risen to the standard he set with his first novel, back in 1983. That said, while Gibson doesn’t display the same ability to tell a story that is compelling from end to end, in this case, Zero History does seem indicative of his maturation as a writer and a person. For instance, whereas the protagonist of Neuromancer was an unrepentent stimulant addict, Zero History explores the psychological processes of addiction recovery in an intriguing and authentic way.

Certainly, one of the interesting aspects of Gibson’s latest work is his exploration of what kind of societal changes may emerge from the most recent real technologies. As he famously remarked: “The future is already here – it’s just not evenly distributed.” In particular, he is concerned with the emergence of wholesale surveillance technologies in areas ranging from international communications to citywide networks of video cameras paired with facial recognition technologies. The ways in which such technologies intersect with the operating practices of governments, criminal syndicates, and special forces groups is certainly something that has cropped up in interesting ways in both reality and other recent fiction, ranging from the assassination of Hamas leader Mahmoud al-Mabhouh in Dubai to the fictional engagement of both police and drug gangs with communication technology on The Wire.

The climax of Zero History is probably the most disappointing part. Without revealing too much about the plot, it seems fair to say that it is a letdown after all the preparation the characters undertake beforehand, and the revelations that follow it do not seem to justify all the earlier intrigue. That said, Gibson’s latest work is a solid piece of fiction and an interesting exploration of some of the implications of emerging and existing technologies. It will also expose a lot of geeks who normally have nothing to do with the world of fashion to some of the elements thereof, in a way that suggests that the industry is not so very different from the high tech sector, with its secrets and large personalities.
