Jeopardy selection starting

As my trivia buddy Aaron pointed out via Twitter, Jeopardy testing is starting today – just the thing for the various species of geek and nerd who I am pleased to say read this blog.

One of Ottawa’s better trivia teams is called ‘I Lost on Jeopardy’. Even if you don’t win on the show, just getting on it might be enough to get them to let you join.

There are scheduled test times for the eastern, central, and Pacific time zones:

  • Tuesday, February 8th at 8:00pm ET
  • Wednesday, February 9th at 8:00pm CT / 7:00pm MT
  • Thursday, February 10th at 8:00pm PT

If you are lucky enough to be in Alaska or Hawaii, the times are 7:00pm (Alaska) and 6:00pm (Hawaii).

The test takes an hour and will only be given once on each of the three nights.

Ballet announcers

It occurred to me that one reason why having an announcer is useful when watching a competitive sport being played is because it reduces how much you need to know and think in order to understand what is going on. Announcers describe things like the histories of particular players, the roles of people in each position, and strategies. This lets you enjoy the spectacle without remembering everything about it, and without having to exert excessive effort to understanding what is going on. That is particularly useful in complicated sports with lots of rules, like baseball and football. Sports obsessives may find it surprising, but I think ordinary people tire of remembering a million complicated rules (just as ordinary people probably tire of the numerous and often arbitrary rules of grammar adored by pedants).

It also occurred to me that there are sports that forego announcers, often at least partly because they clash with the sport’s aesthetic. Dancers, figure skaters, and ballet dancers are expected to be silent and make it look easy. Having announcers overlaid on top of them seems crass, and like it would detract from the art.

It could be an interesting performance piece, however, to overlay constant narration onto an athletic performance that usually lacks it. A ballet with hockey-style announcers might be more accessible to people who don’t know much about ballet and who don’t want to spend the whole show puzzling about what is going on (the same reason there are short summaries at the start of Shakespeare’s plays – perhaps modern novels should have those too).

Now or Never

Tim Flannery’s slim book Now or Never: Why We Need to Act Now to Achieve a Sustainable Future does not mince words, when it comes to describing the seriousness of the situation humanity now finds itself in, with regards to the diminishing capacity of the planet to sustain human flourishing:

There is no real debate about how serious our predicament is: all plausible projections indicate that over the next forty to fifty years humanity will exceed – in all probability by about 100 percent – the capacity of Earth to supply our needs, thereby greatly exacerbating the risk of widespread starvation, or of being overwhelmed by our own pollution.

Flannery, previously known for his book The Weather Makers, describes the latest climatic science as detailed by James Hansen before scoping out some of the options that exist for mitigating its seriousness, if humanity acts quickly enough.

Flannery is also forthright on the matter of just how difficult it will be to prevent unacceptable amounts of climate change – hinting (but never saying directly) that geoengineering may be required. The book places a strong emphasis on the possibility of drawing carbon dioxide from the air and into biological sinks, and considers the role that carbon markets and offsets could play in driving such actions. It does not adequately consider the issue of certainty, however. To be really worthwhile, the carbon needs to be removed from the atmosphere indefinitely – something that cannot really be ensured by planting trees (which could burn or be cut down) or enriching soils with carbon (which could be re-released).

All in all, I wasn’t hugely impressed with Flannery’s argument. He seemed overly focused on defending livestock agriculture, too bullish on pyrolysis and biochar as sequestration techniques, and overly eager to attribute intentions to nature. At many points, Flannery brings up the Gaia Hypothesis, which I think is often dangerously misleading in its implications. There is no reason to believe the Earth ‘prefers’ one state or another, or that it will always respond to shocks by moving back in the direction of how it was. Rather, there is evidence from the paleoclimatic record that when the climate system is pushed aggressively enough, it can swing into dramatic new states, in a way that could be profoundly hostile for humanity and most of the planet’s other species.

One of the most interesting aspects of the book is the inclusion of responses written by prominent individuals including Peter Singer (who very effectively rebuts Flannery’s argument that meat eating isn’t too problematic) and Bill McKibben. In his response, Gwynne Dyer neatly responds to some of the book’s Gaia language, while also making a key overall point:

Whether you want to dress [knowing human manipulation of the climate] up as human beings becoming the consciousness of Gaia, or just see us as the same old self-serving species we always were, we are taking control of the planet’s climate. This billions-strong human civilization will live or die by its success in understanding the global carbon cycle and modifying it as necessary to preserve our preferred climate.

Those key points – the seriousness of the risk of climate change and the importance of taking action in response – have not yet really been absorbed by either the general public or the world’s political elite. If that is to change in time for the very worst possible outcomes to be avoided, that needs to change quickly. By helping to publicize those key facts, Flannery certainly seems to be helping that process, even if there are valid criticisms that can be raised against some of his perspectives and proposed responses.

Fewer photos to Facebook

Because of how they get their money, it seems to me that Facebook has a business model that is fundamentally opposed to the interests of its users. Since they don’t pay monthly fees, they aren’t Facebook’s customers. Instead, they are Facebook’s product, which is then sold to advertisers in the form of eyeballs and (more worrisomely) databases of personal information.

Because of that, Facebook is never going to be proactively involved in protecting privacy. Instead, it will always be pushing the boundary and doing as much as users are willing to accept. Bit by bit – visibly and invisibly – it seems that privacy protections will be eaten away and more and more data will be available to Facebook’s real clients, the advertisers.

In response to this, I have been gradually stripping down my profile. That’s not all that possible, however. For one thing, Facebook never forgets information you entered, even if you delete it. For another, it can guess all sorts of things about you based on your friends. It can guess what sort of products you are likely to buy, or even if you are gay.

Some people may not be bothered by this, but I am. As such, I am going to shift away from posting photography on Facebook. Instead, I will mostly rely on Flickr Pro, which is a paid and user-focused service.

[Update: 6:39pm] Fear not, photo appreciators! There will still be photos uploaded, and they are likely to be in smaller batches of higher quality work. These are from today: Rideau Canal Skating 2011.

Outliers: The Story of Success

One thing that sets apart the writing of Malcolm Gladwell is the ease with which it is devoured. His books always provide the reader with the sense that they are taking in important new information, and doing so unusually quickly and easily. In Outliers: The Story of Success, Gladwell argues convincingly the the level of success people achieve has an enormous amount to do with the conditions in which they lived. How your parents raise you is important, as is the cultural legacy you inherit. Even arbitrary-seeming things like when in the year you were born can have a demonstrable effect, particularly in sports.

This book has been analyzed to death in the popular press, so there isn’t much point in me recapping it. Talking about highly successful people like Michael Jordan and Bill Gates, Gladwell argues that:

[They] appear at first blush to lie outside ordinary experience. But they don’t. They are products of history and community, of opportunity and legacy. Their success is not exceptional or mysterious. It is grounded in a web of advantages and inheritances, some deserved, some not, some earned, some just plain lucky – but all critical to making them who they are. The outlier, in the end, is not an outlier at all.

In the course of his examination, Gladwell reaches practical conclusions for both individuals and societies. As an individual, if you wish to prosper you must practice an exceptional amount – effort put in can be the most important factor. For society at large:

To build a better world we need to replace the patchwork of lucky breaks and arbitrary advantages that today determine success – the fortunate birth dates and accidents of history – with a society that provides opportunities for all.

He provides some concrete examples of how that could be done: for instance, by delaying the streaming of young children by talent, by providing summer school for low-income children, by encouraging children to assert themselves around and question adults, and so on.

I only have a few quibbles with the book. Sometimes, Gladwell uses vague language. What does it mean to say that $X were ‘involved’ in mergers and acquisitions during the 1980s? Occasionally, he speculates beyond what the evidence he includes can justify. I also think Gladwell is wrong to say that a Boeing 747 contains “212,000 kilograms of steel”. Aluminum is a lot more likely.

Gladwell’s book is engaging, using techniques that many academics would shun as showmanship. For instance, Gladwell sometimes makes a bold promise early in a chapter, saying he will prove an unlikely-seeming statement to be true (“it is possible to… predict the family background, age, and origin of [New York City’s] most powerful attorneys, without knowing a single additional fact about them”), or adds a bit of theatre (“in this chapter, we’re going to conduct [an aircraft] crash investigation”). Partly through such techniques, the book gets across some interesting examples and arguments quickly. It is particularly interesting to see him explain situations in which things that seem like disadvantages – like anti-Semitism in New York law firms – turn out to be highly advantageous to the people who you would expect to be disadvantaged (because they ended up going into areas of law shunned by the established firms, which became important and profitable).

Gladwell’s message is simultaneously empowering and disempowering. By revealing some apparently important underlying dynamics, he may help readers decide how to focus their energies. At the same time, he points out how a lot of the characteristics our lives will have emerge predictably from pre-set characteristics which we cannot alter or control. Indeed, by influencing our thinking about the sources of success, Gladwell affects the inputs that go into our reasoning about ethics. In particular, if people achieve high levels of financial success largely because of arbitrary factors outside their control (or fail financially for the same reasons), the argument for income redistribution looks a lot stronger.

[Update: 7 February 2011] I reviewed another of Gladwell’s books previously: The Tipping Point: How Little Things Can Make a Big Difference.

High school science

Talking with Emily the other night, I was reminded of something that happened to me while I was attending Handsworth Secondary School, in North Vancouver. I can’t remember which grade it was in, but I had a large group lecture in ‘science’ (back before they were split by sub-discipline) and one topic covered was buoyancy.

The lecture was taught by Mr. Salkus, one of the two or three teachers who I remember being seriously important for me in high school. At the end, he presented a problem to the class: working out how many five gram helium balloons of a set volume it would require to lift him. Naturally, his weight was provided.

Because I left elementary school having read all the science books I could handle, I started high school with quite a head start in chemistry, physics, and biology. I remember the The Usborne Illustrated Dictionary of Chemistry and the The Usborne Illustrated Dictionary of Physics being favourite childhood texts. (Parents, buy them for your children!) As a result, I was allowed to take Science 8 and Science 9 simultaneously, and move to Science 10 in 9th grade.

One problem with this approach is that my math lagged behind. Math also wasn’t a subject I was particularly strong in. Along with French and gym, it introduced Cs into my high school report cards. I remember, in Chemistry 12, having my brilliant lab partner explain that a problem could be solved easily using an integral, but having no idea how such a thing was done. (Later, as an undergrad, I had a similar experience in an early economics course with regressions.)

So, at the time of this balloon lifting problem, I was not comfortable with algebra. I knew that an algebraic equation would be the way to work out the answer: first by comparing the density of air and helium, then by working out the net lift from each balloon. What I didn’t know was the mathematical technique for doing this properly. Instead, I solved it using an arithmetic kludge.

A prize had been promised to whoever got the answer right, and I remember submitting mine (one of only a small few who did) with nervousness, given that I knew my approach to be somewhat faulty. The next lecture, however, Mr. Salkus gave me a mini Toblerone bar, along with the two students who had actually solved the problem correctly. Maybe he realized that my math classes had lagged behind my science classes; maybe he just felt inclined to reward my effort. In any case, it was one of the things that made me remember him as an unusually good teacher.

Crediting friends for photos

I put a lot of photography online. I try to put a photo per day up on this site, and I have heaps of photos on Facebook and Flickr. It’s a hobby I enjoy and people seem to enjoy seeing my photos, including ones of themselves.

As photo and computer gear have made it easier and easier to store large numbers of digital images, my library is ballooning. I use iPhoto to store ‘digital negatives’ and currently have an album of 36,109 photos. Most of those photos (over 2/3) have been taken since I came to Ottawa.

While lugging around a giant SLR, it is fun to let other people try taking a few shots. One person brought the gear, but that doesn’t mean people with different perspectives shouldn’t be allowed to make use of it.

I do try to memorize which shots are mine and which ones were taken by others, but I deal with a daunting number of photographs overall. Once in a while, I may accidentally mis-attribute a photo taken by someone else as my own. It is never my intention to do so, and I ask you not to be offended if I haven’t remembered which shots you took. I would always be pleased if you would let me know, so that I can provide an appropriate caption or hover-over text.

Does that seem like a sensible approach to people?

Bell, usage based billing, and TekSavvy

It seems the Canadian Radio-television and Telecommunications Commission (CRTC) has let the dominant internet service provider (ISP) Bell largely ruin the smaller ISP Teksavvy:

From March 1 on, users of the up to 5 Mbps packages in Ontario can expect a usage cap of 25GB (60GB in Quebec), substantially down from the 200GB or unlimited deals TekSavvy was able to offer before the CRTC’s decision to impose usage based billing…

We encourage you to monitor your usage carefully, as the CRTC has imposed a very high overage rate, above your new monthly limit, of $1.90 per gigabyte ($2.35 per gigabyte in Quebec).

Forcing big companies like Bell to lease capacity to companies like Teksavvy seems very smart, as it helps prevent dominant monopolies from forming. Unfortunately, such arrangements don’t have much meaning if you also allow the big company to force their own policies on the smaller companies that are leasing from them.

Consider the case of a customer using 100 GB a month – half of Teksavvy’s previous low cap. Before, they would have paid $44.30 with tax. Under the new rules, they would pay that plus another $142.50 in additional data usage fees.

AdBlock arms race?

I have been happily using AdBlock for years, with few if any inconveniences resulting. Lately, however, I have noticed websites partially sabotaging themselves for AdBlock users. I suppose this makes sense – they must hate the loss of advertising revenue.

It wouldn’t surprise me if even the sites that aren’t taking action in response to AdBlock now are tracking which of their visitors have used the software in the past.
