Graduating from Oxford

Given the following:

  1. I am doing as much as possible to avoid air travel, due to the carbon emissions associated.
  2. If I were going to fly, it would be (a) to deal with some kind of emergency or possibly (b) for an extended visit to a previously unseen part of the world.
  3. You only get one chance to graduate at Oxford, either in person or in absentia.
  4. There is no particular urgency in formally graduating.

Should I apply to have my name read in my absence and receive my diploma in the mail?

Unreliable Sylvania

The two selling features of compact fluorescent bulbs are higher efficiency (more light produced per unit energy) and longer lifespan, when compared to incandescent bulbs. We have already established that the first isn’t a concern for people actively heating their homes. My recent experience with the second is also rather negative. I recently replaced as many bulbs in my house as possible with fluorescents. In the month and a half that followed, four of the bulbs failed: those in my kitchen, on my back porch, and in my front hallway.

I have never had incandescent lights fail so quickly. It’s not clear what caused these ones to die so abruptly (A manufacturing defect? Problems with my power supply?), but it will definitely prevent me from buying Sylvania brand bulbs in the future.

Am I a ‘conservative?’

The other day, a friend of mine somewhat surprised me by referring to me as a ‘conservative.’ Pressed to define myself, I would say that I am a pragmatic libertarian who is willing to recognize that our freedoms need to be constrained in many ways in order to live decently together.

The Political Compass test categorizes me as follows: moderately left wing on economics (-3.00) and strongly slanted towards libertarianism rather than authoritarianism (-6.67).

I do object to some of the questions they pose. For instance:

  1. If economic globalisation is inevitable, it should primarily serve humanity rather than the interests of trans-national corporations – It is a bit silly to say that globalization serves one or the other, or that corporations are purely abstract entities whose welfare has nothing to do with individual people.
  2. The only social responsibility of a company should be to deliver a profit to its shareholders – This seems like an oversimplification of a complex question. Clearly, corporations have a general obligation to obey the law (though those in them may sometimes be morally obliged to break unjust laws). It certainly isn’t clear that the directors of corporations should undertake charity using shareholder wealth.
  3. First-generation immigrants can never be fully integrated within their new country – This clearly depends on what constitutes integration. For instance, when there are societies that have multiculturalism and inclusiveness as important features, people can be integrated without being assimilated.

The test also features a number of confusingly worded multiple-negative items. “Is X not true? No.” There are also a few questions seemingly designed to establish whether you are a racist. It seems to me that there have probably been racists of all possible political affiliations.

Personally, I would say my political philosophy is a combination of some classically liberal ways of viewing the world coupled with a libertarian concern for the individual and a utilitarian concern for group welfare. I would say that I am also unusually aware of the extent to which seemingly private decisions (what to eat, how to travel, etc) have significant and morally relevant impacts on other people.

Summer has passed

Some facts for the autumnal equinox:

  • The Earth has seasons because it orbits the sun while tilted 23.44˚ off the vertical axis.
  • This tilt varies with time, following a 41,000 year cycle.
  • At the maximum, the tilt is 24.5˚. At the minimum, it is 22.1˚. When there is more tilt, the difference between summer and winter increases. When there is less tilt, the seasons are more similar.
  • Along with the changes in the shape of Earth’s orbit (eccentricity – 100,000 year cycle) and the way the planet wobbles around the pole (precession – 26,000 year cycle), axial tilt (obliquity) contributes to the Milankovitch cycles – one of the major long-term drivers of natural climate change.
  • To learn more, look up Dansgaard-Oeschger events and Heinrich events.

Disclaimer: Yes, orbital and solar variations affect the planet’s climate. That doesn’t mean human greenhouse gas emissions don’t, nor that they aren’t the primary cause of the climate change presently taking place!

Voting algorithm flowchart for Canadian elections

The above is based on a few simple rules:

  1. If you have the chance to influence the outcome in a preferable way, do so.
  2. If you cannot, use your vote in symbolic support of whichever platform you find most appealing,
  3. Provided they have fielded a decent candidate in your riding.

It is a pragmatic approach that I think can be applied regardless of one’s political beliefs or ideology.

How would other people structure this differently? Note that it doesn’t address any issues about why you prefer one platform to another, nor what characteristics you would find unacceptable in your representative.

Salade Spot in Gatineau

Those who work in Gatineau should consider Restaurant Salade Spot as a quicker and cheaper alternative to Gaia. Located at 175 Promenade de Portage, it sells wraps and salads starting at $4.50 and $5.50 respectively. For $7.90, I got a large spinach salad with artichoke hearts, tomatoes, green olives, black beans, hard boiled eggs, blue cheese, and honey mustard dressing – including the $2.00 cost for a re-usable plastic container for it. Those who buy or bring a re-usable container get two free extra ingredients for their salad. Mine was markedly better than an equally filling meal of similar price from Marcello’s or Subway.

Apparently, they also source as many of their ingredients as possible locally. All told, it is definitely a place worth trying for those working in Place de Portage, les Terrasses de la Chaudière, and the vicinity.

[Update: 14 April 2009] It seems Salade Spot went bankrupt. I went there for lunch today and found the windows papered over and a ‘for sale’ sign up. There was no indication that the place had relocated, rather than shut down.

Brunch with Ottawa bloggers

Last weekend involved a brunch attended by local bloggers, not unlike the four bloggers’ gatherings I attended in Oxford. Zoom has kindly provided the internet with her notes about what occurred and was discussed. An embarrassingly large number of items consist of esoteric topics that I raised. Many thanks to Zoom and XUP for organizing the gathering.

Incidentally, the Clocktower Pub (575 Bank Street) has a rather tasty four-cheese omelet on their brunch menu. It is both reasonably priced and very well stuffed with tasty melted cheese.

Replacing the keyboard on a G4 iBook

Back in April, I managed to spill coffee on the keyboard of my 14″ iBook, disabling a number of keys. Now, I have managed to return it to functionality for less cost than anticipated.

The authorized Apple repair places in Ottawa wanted $45 just to diagnose the problem – specifically, to determine if the failure lay in the keyboard itself or the logic board it connects to. Replacing the keyboard would then cost extra for parts and labour. Replacing the logic board would be quite a significant expense, largely because the machine would have to be seriously taken apart.

Instead of taking it into a shop, I bought a replacement keyboard on eBay for about $30. Had it been a logic board issue, I would have diagnosed it myself for a lesser cost, which could have been further reduced by re-selling the replacement keyboard. As it happens, the new keyboard works fine. The process of installing it is pretty straightforward:

  1. Shut down computer. Remove power cord and battery.
  2. Lift plastic tabs at the top of the keyboard so it can swing upward towards you. Lay the partially removed keyboard flat across the area with the touchpad.
  3. Ground yourself by touching something metal, to prevent static shock to the components.
  4. If present, remove the AirPort card by gently pulling it towards the screen. Gently remove the plug connecting it to the motherboard.
  5. Use a tiny screwdriver to remove the four tiny screws holding down the aluminum plate under the space where an AirPort card goes.
  6. Lift off that plate.
  7. Pull the keyboard connector out of the motherboard. In my experience, it takes a moderate amount of force to make it disconnect.
  8. Position the new keyboard where the old one was, lying keys-down on the trackpad area.
  9. Plug the new keyboard into the logic board, as before.
  10. Replace the aluminum plate. Replace the four screws.
  11. If present, replace the AirPort card by plugging the connector into it, then clicking it back where it was previously.
  12. Place the keyboard back in its normal position, allowing the tabs to click it into place.

I am always suspicious that stuff I buy on eBay is counterfeit. This keyboard certainly looks identical to the old one. I am less sure about the sounds and feeling of the keys, but that may just be because I had grown used to how an old keyboard feels, followed by the feeling of Apple’s nice new aluminum external keyboards.

The replacement keyboard is definitely squeakier than would be ideal (particularly in terms of the spacebar). Hopefully, it will mellow with use.
