Are embassies still necessary?

Dylan Prazak

This Vanity Fair article discusses the evolution of American embassies from open glassy structures intended to be a concrete reflection of American values into fortresses that almost completely isolate those inside from the country hosting them. This is certainly true of the new embassy in Baghdad. It has its own electricity and water supply and it is sharply isolated from even the ‘Green Zone,’ which is itself a fortress for foreign occupiers. The article goes on to ask whether embassies are even really necessary, in this age of mass communications:

Faced with the failure of an obsolete idea—the necessity of traditional embassies and all the elaboration they entail—we have not stood back to remember their purpose, but have plunged ahead with closely focused concentration to build them bigger and stronger. One day soon they may reach a state of perfection: impregnable and pointless.

There is certainly something to the argument. If the people working there are completely out of contact with the local population, they may as well be located in their home state. Due to security concerns, day to day matters like visas and assistance for tourists are increasingly handled at locations aside from embassies. Perhaps all ambassadors need these days is some secure office space, a home in a well defended gated community, and the ability to rent facilities where large social functions could take place. Eliminating embassy compounds would remove a tempting target for terrorists, and allow a lot less diplomatic and local staff to be retained.

In the end, the two key questions seem to be:

  1. Do embassies still do anything that couldn’t be accomplished by fewer people in less specialized secure facilities?
  2. Do any of those enduring purposes justify the risk and expense now associated with embassy construction and operation?

It seems to me that the answers may be ‘not much’ and ‘often, no.’ The most important remaining role for many embassies may be in espionage: snatching up nearby radio transmissions and providing some land that operates under the legal regime of the ambassador’s home state.

Colour temperature and photography

Eye exams on Somerset

One way in which colours are categorized is according to the temperatures at which materials emit them, when heated in a vacuum. The phenomenon of warm things emitting light can be observed readily: for instance, when a bar of iron is heated from red, to orange, to yellow, to white. Some of the key colours photographically are those akin to the light of the sun around noon (about 5500° Kelvin) and the light from incandescent bulbs (about 3300° K). Just as with the heated iron bar, the hotter the light source, the ‘cooler’ the temperature appears: ranging from reds and oranges at low temperatures up to greens and blues. This can be a bit confusing, since the colours artists describe as ‘warm’ are actually produced by low temperatures, and vice versa.

Virtually all digital cameras have the ability to adapt to different colour temperatures. This is important because our eyes generally make the correction automatically. Looking at a scene under fluorescent lights, it doesn’t seem as green to us as it really is – and will appear on film or an uncalibrated digital sensor. Exactly how you set the white balance on your camera varies by model and manufacturer, but it is worth checking the manual over.

In addition to being used to correct for the dominant type of lighting in a scene, colour balance can be set so as to create a desired look that may not have been present in the original scene. For example, intentionally using the white balance for warm light (low temperature) in a scene with cool light (high temperature) exaggerates the cool light in the scene. As a result, you get a very cool looking photo like this one. By contrast, intentionally using the white balance for cool light (high temperature) in a scene that already has fairly warm light will exaggerate the warm light, as with this photo.

For users of Canon cameras, here is an easy way to try this out:

  • First, head out on a cold winter’s day and find a wintery looking scene.
  • Then, go into the white balance setting for your camera. If you have a point and shoot camera, this is normally done by setting the control dial on your camera to ‘P,’ then pressing the ‘Func. Set’ button in the middle of the wheel on the back. Scroll down once and you should be in the white balance menu. Press the ‘right’ button until you have ‘Tungsten’ selected.
  • If you have a digital SLR, there is usually a dedicated white balance button on the back, labelled ‘WB.’
  • Shoot the winter scene with that setting, and you will get a cool blue looking result.
  • Secondly, try shooting a warmish scene (such as one taken around sunset outside) with the camera set to ‘Cloudy.’ That will make it look even warmer, which is sometimes attractive.

When you choose a colour balance setting on your digital camera, you are telling it how to process the raw data from the sensor into a JPG image. Since the raw data isn’t normally retained, this is an irreversible choice (though it is possible to approximate a white balance change using software like Photoshop). For cameras capable of recording the data from the sensor as a RAW file, you will be able to select whatever white balance you like after the photo has been taken. Thanks to CHDK, a great many Canon cameras (including inexpensive point and shoot models) can be given this capability.

Incidentally, the matter of what wavelength of light is emitted by objects of different temperatures is a key part of the physics of climate change. One neat thing about science is the way you often run into aspects of one field that are relevant somewhere very different.

Large-flaked snowfall

Lately, Ottawa has seen a bit of my favourite kind of snow: the sort where the flakes are large, slow to fall, and capable of being pushed and spun around by the wind. It is especially pretty to watch from inside a high tower, since the different air currents outside give the impression that as much of it is floating upwards as is falling down.

Despite the lengthening days, the good people of Ottawa still have a few more months in which to sample the many kinds of snow available, as well as the various winds that contribute to the mood of a snowstorm.

Internet footprints and future scrutiny

Frozen blue lake, Vermont

Both The Economist and Slate have recently featured articles about the increasingly long and broad trails people are leaving behind themselves online: everything from comments in forums to Facebook profiles to uploaded photographs. Almost inevitably, some of this content is not the kind of thing that people will later want to see in the hands of their employers, the media, and so forth. I expect that more savvy employers are already taking a discreet peek online, when evaluating potential hires.

The two big questions both seem to concern how attitudes will evolve, both among internet users in general and among scrutinizers like employers. It’s possible that people thirty years from now will view our open and informal use of the internet as roughly equivalent to the famously uninhibited sex had by hippies in the 1960s: a bit of a remarkable cultural phenomenon, but one long dead due to the dangers inherent. It is also possible that people will come to view the existence of such information online as an inevitability, and not judge people too harshly as a result. Less and less human communication is the ephemeral sort, where all record ceases once a person’s voice has attenuated. As a result, more of what people say and do at all times of their lives (and in all states of mind) is being recorded, often in a rather durable way.

Personally, I suspect that the trend will be towards both greater caution and greater tolerance. Internet users will become more intuitively aware of the footprints they are leaving (especially as more high-profile cases of major embarrassment arise) and employers and the media will inevitably recognize that almost nobody has produced a completely clean sheet for themselves. Of course, there will still be a big difference between appearing in photographs of booze-fueled university parties and appearing at KKK rallies. The likely trend is not that a wider range of activities will be excusable, but rather that more evidence about everything a person has done will be available.

We can also expect the emergence of more private firms that seek to manage online presence, especially after the fact. Whether that means bullying (or bribing) the owners of websites where unwanted content has cropped up, creating positive-looking pages that outrank negative ones, or stripping away elements of databases through whatever means necessary, there will be a market for data sanitation services. While some people are likely to push for revamped privacy laws, I don’t see these are likely to be much help in this situation. When people are basically putting this information out in public voluntarily, it’s not clear how legislation could keep it from being scrutinized by anyone who is interested.

Television shows to borrow

Buying television programs on DVD or renting them disc-by-disc often costs about the same amount, and the latter leaves you with discs to lend to others. If someone I know in Ottawa wants to borrow one of these, they should let me know:

  • Blue Planet
  • House, Season I
  • House, Season II
  • House, Season III
  • Invader Zim, Season I
  • Invader Zim, Season II
  • Planet Earth
  • The Sopranos, Season I
  • The Sopranos, Season II
  • The Wire, Season I

I would be especially keen to make a temporary exchange with someone who has the second season of Rome, or any subsequent season of The Wire or The Sopranos.

Location data and photography

Dylan and Dusty

Before long, I expect that many cameras will have built-in GPS receivers and the option to automatically tag every photo with the geographic coordinates of the place where it was taken. That will allow for some neat new kinds of displays: from personal photo maps that show the results of a single person’s travels to composites of the photos a great many people have taken of the same place.

For those who would be interested in such things, but don’t yet have equipment that can locate itself, it seems like there could be a simple workaround. These days, low-cost GPS tracking devices are very affordable. All you need is a camera and a tracker with coordinated clocks. Then, you carry the tracker with you when you take photos. After you upload them to a computer, you can run software to automatically attach location data from the tracking system to the photos. Given the increasing number of cell phones with GPS capability, they might be the ideal devices to provide such locational data. You could even configure one to automatically upload a track of your movements to a web service which would then match up that information with photos you upload later.

One snag would be photos taken in areas where GPS doesn’t work, such as on the subway. To deal with that, users could be presented with a few choices. The coordinates from the closest point in time where data is available could be used, a very general coordinate for the city or region in question could be substituted, or such photos could simply be left untagged.

No doubt, people could dream up some very clever ways of using this kind of data, especially once a lot of it was online. You could, for instance, produce collages of how a particular area looked over time. A mountain valley could be presented from the perspectives of everyone from those hosting afternoon picnics to those undertaking technical climbs of the peaks, with spring and summer photos contrasted against snowy winter shots. Groups of friends could also watch their trails of photos diverge and overlap, as they move around the world.

All told, it could be a very interesting experiment in communal memory.

Sorting digital music

Fence in Vermont

When it comes to the organization of music, I am probably one of the most obsessive people out there. I would actually rather delete a song I cannot properly categorize than retain it as ‘Track 1’ by ‘Unknown Artist.’ Also, once I start categorizing something such as music or photos, I cannot rest easy until the task is done. It’s a tendency I need to be aware of and careful about. The decision to tag all my iPhoto images for which friends are in them, for example, produced about three days worth of intense work.

Of course, iTunes is the ultimate enabler for music organization obsessives. It puts everything into a big database: song ratings (all my songs are rated), artists, titles, play counts, last played dates, etc. It lets you set up smart playlists that, for example, consist only of songs rated four or five stars and haven’t been played in the last two weeks. You can also tag your songs as Canadian, too obscene to be included in a random party playlist, or whatever other designations are useful to you. I have most of my good music sorted into mood-based categories, including angry, brazen, demure, dramatic, energetic, rebellious, sombre, and upbeat.

One annoying element of the age of digital music is the enduring character of mix CDs consisting of CD-style music tracks, rather than data files. Almost invariably, this means that someone somewhere converted the uncompressed music on a CD into an MP3, AAC, or WMA file. Then, someone took that compressed file and stretched it back into CD format. If you then try to re-compressed the previously compressed and de-compressed file, you encounter a notable loss of quality. It would be far better if people made mix CDs consisting of data files (those in a lossless format would be especially appreciated, and still significantly smaller than uncompressed music files).

One final annoyance I will mention is the fact that my iPod is no longer large enough to store my music collection. Since I am now about 500 megabytes beyond its capacity, I need to manually ‘uncheck’ songs so that it can synchronize properly. Beyond being a pain, this somewhat undermines the iPod concept, which is really to have all your music available at a touch. My iPod is an old 4th generation 20GB model. It was replaced four times under an extended warranty that has since expired, and it probably doesn’t have enormously more time left in the world of working gear. When it bites the bullet, I will buy something large enough to store many years worth of future musical acquisitions.

Climate in 2009: predictions

Robert Pini

Two related events are likely to dominate climate news for 2009: the first year of the Obama administration and the UNFCCC negotiations in Copenhagen. Arguably, the biggest open question is just how dedicated Obama will be to domestic and international climate change action. It may be that he lives up to the high expectations of the environmental community, setting the stage for the rapid deployment of a cap-and-trade carbon pricing system in the United States and playing a constructive role in the creation of an international legal instrument to succeed the Kyoto Protocol. It may also be that his focus lies elsewhere, or that Congressional opposition makes his platform harder to implement. The Obama administration failing to make climate a priority issue from the outset is probably the most likely ‘bad news’ climate story of 2009, whereas successful domestic and international engagement is probably the most likely ‘good news’ story.

American re-engagement with the UNFCCC process is a necessary condition for progress, but it will not be sufficient in itself. Much depends on whether India and China can be brought into the agreement, as well as whether deforestation can be successfully incorporated into a new accord. Given the urgency of reducing emissions (starting the long path to stabilizing atmospheric concentrations of greenhouse gasses), it must be hoped that all the key states will rise to the challenge and develop a fair and effective approach.

If there are going to be big climatic surprises in 2009, they are more likely to be physical than political. It is nearly certain that there will be strange and destructive weather somewhere, and that at least some people will attribute it to climate change (whether plausibly or not). A big surprise could take the form of an extreme weather event, or simply the sharp acceleration of a tend such as glacier loss, permafrost melting, or changes in precipitation patterns.

With luck, 2009 will be seen as the year in which the world really began turning the corner towards emissions reductions. Most of the governments most bitterly opposed to action on climate change have been eliminated, and an accord between the big players (the US, China, Japan, Europe, etc) would have the momentum to drag everyone else along. The road ahead will continue to include shifts in policy – as well as very active debates on who should bear which costs – but the general outlines could be affirmed this year and global implementation could begin in earnest. Those broad outlines include the need for both total and per-capita emissions to start falling globally (perhaps with a brief period of residual growth in very poor states), that per-capita emissions should converge between all states, and that many of the costs of global mitigation and adaptation be borne by the societies that have created the problem.

For the sake of all future generations, let’s hope this will be a year of great progress.
