UBC warns of the dangers of international online learning

I cannot recall hearing about a warning like this before:

Some UBC courses might cover topics that are censored or considered illegal by non-Canadian government… This may include, but is not limited to, human rights, representative government, defamation, obscenity, gender or sexuality, and historical or current geopolitical controversies… Students should be mindful that when they partake in class discussions or communicate to the members of the class, that for some students living abroad, sensitive material might result in repercussions.

It has been sad to watch the hopeful vision of an unfettered global internet linking together humanity collide with the interests and increasing willingness to intervene of governments. I don’t think it’s plausible, but it would be great if the next-generation satellite internet providers like StarLink would be willing to provide access to everyone underneath their constellation without government censorship and firewalls.

Cyber defences create their own risks

In addition to aforementioned rules about internet and computer security (1, 2, 3, 4) it’s worth mentioning that security measures can create their own vulnerabilities.

That’s true in terms of human systems. For instance, granting high-level powers to system administrators creates risks that they will exploit them deliberately or have their credentials stolen, or simply used after being left unguarded.

It’s can also be true for technical means. For instance, people often misunderstand TOR and believe that it makes everything about their web browsing anonymous. Really, it just routes the traffic several times within an encrypted network to disguise the origin before using an exit node to communicate with the target server, potentially with no encryption. Since people may be more likely to use TOR for sensitive or illicit purposes, those exit nodes are likely a target for both freelancers and governments.

Some recent stories have alleged that the virtual private networks (VPNs) which people use to protect themselves from an untrusted local network can create risks as well:

Earlier, people alleged that Facebook was using its Onavo VPN to snoop on users.

Government and law enforcement back doors

One computer security concern is that various insiders — including hardware and software manufacturers, and governments which may compel them to comply — will build back doors into their products to allow the security to be compromised.

Doing this is a terrible idea. A back door put in for government surveillance or police use is also vulnerable to use for any purpose by anyone who discovers it. There’s no way to create strong encryption and security against everyone except the government, so building in back doors means deliberately spreading insecure systems throughout your society. When you deliberately design your systems to be vulnerable to one attacker (however well-motivated and regulated) you inevitably create an attack vector for an unauthorized person. You also face vulnerability if the mechanism of the backdoor is reverse engineered by unregulated agents, like criminal groups or foreign governments. With the degree of espionage focused in high-tech industry, it’s hard to imagine that any government could keep their back door strictly for their own use when well-resourced and determined opponents would also achieve many objectives through access.

The latest high-profile example of such a back door is the revelation that Swiss cryptography firm Crypto AG was secretly owned by the CIA. There have been numerous recent news stories, but the same information was reported in 1995. The National Security Archive has some further context.

twitter’s an addictive land of trolls

I have written before about the cognitive and emotional (and insomniac) downsides of checking the news too often. It seems worth re-emphasizing how twitter is a worst-case scenario in this regard, at least for people more interested in developments in matters of public interest than developments in the lives of friends and acquaintances, where facebook is untouchable.

With twitter it’s possible to use any internet-connected device to get an endless stream of updates and — crucially — little decisions for as long as you want at any time of day. It’s an exercise perfectly crafted to short-circuit longer term planning, even at the scale of turning off your phone to get a night’s rest before a busy day tomorrow. Every tweet presents the cognitive task of interpreting the content; determining whether it contains any factual, ethical, or political claims; and then evaluating that content in light of what the user believes and what, if anything, they are trying to accomplish through engagement online. Even for fairly passive users, every tweet involves the decision of whether to publicly ‘like’ or ‘retweet’ it, forcing your brain to engage decision-making circuitry more often and immediately than when reading a news article or book. Of course the real addictive prompts come from the social features: the notifications that someone has ‘liked’ or responded to your tweet. That engages all the emotional machinery which we use to socialize with others, maintain or alter our beliefs about the world, and protect out own self-esteem. It also embodies the slot machine logic of unpredictable and variable responses to the same action, ranging from someone amazing expressing agreement or saying something clever in response to your message to the depredations of the most hateful trolls.

Twitter often exposes me to content which I subsequently wish I could unsee, including particularly blockheaded claims and arguments which tend to re-emerge with a sense of frustration and anger in the shower the next day. The platform isn’t entirely without virtues — it can provide useful or at least engaging up-to-the-minute information and analysis on ongoing events, it allows users to engage directly with people who would otherwise be inaccessible, and perhaps it does sometimes direct people to good quality information they wouldn’t otherwise see. At the same time, it’s the venue for the least pleasant interactions in my life and it’s a repository of almost limitless idiocy and unkindness.

I have resolved for now to “cut off the time wasters quickly. They can’t be won over and whatever value there is in publicly refuting their arguments doesn’t justify the time and stress commitment”. There’s really no alternative strategy possible, since the platform is so full of people who (a) aren’t debating in good faith (b) can never be convinced or won over and (c) only get nastier with repeated interaction. They can take decades of meticulously collected, analyzed, and reviewed scientist and ‘refute‘ it with a silly accusation about the scientist or the person referencing them, a conspiracy theory, or an disreputable source which is nonetheless equally accessible online. Maybe very early on engaging with them helps draw some of the undecideds who are silently observing toward well-supported beliefs, but that almost certainly ceases to be true once your back and forth with that person has become one of your top ten present-moment sources of annoyance and irritability.

Hypocrisy back and forth

Blair King (whose blog bio says he has an “Interdisciplinary PhD in Chemistry and Environmental Studies”) is one of the people who had sent a tweet arguing that only people who use few or no fossil fuels can call for decarbonization and who I linked to this rebuttal post. He subsequently wrote his own response to me. I appreciate the substantive quality of what he wrote, but I still disagree with his conclusions.

To begin with, he says:

The reason the charge of hypocrisy is used so often in this debate is because it represents a valid concern. We live in a world full of hypocrites who will say one thing in public and do another in the privacy of their own lives. The problem is that until you have personally tried to go without fossil fuels you can’t really understand how hard it really will be. So a hypocrite is apt to make claims that are not founded on an understanding of the scope of the challenge, usually that doing so will be relatively easy

Fair comment, but I don’t think I understate the cost, difficulty, or challenge of rebuilding of the global energy system, nor automatically assume people in the future will use as much energy as we do today. Saving the biosphere justifies major lifestyle changes.

He goes on to say: “[t]o suggest that we can make massive global political changes without anyone making individual changes represents magical thinking”. That’s not what I have been saying at all. My point is that it’s wrongheaded to argue that only people who don’t use oil can call for decarbonization and further that efforts at addressing climate change through voluntary individual action are hopeless. People will definitely need to make changes, but they won’t for the most part be voluntary and individual. People don’t individually decide what sort of power plants get built, where our raw materials come from, or how any part of our integrated, technological global society functions. A lot of those systems have actually been set up by larger entities like corporations and governments making choices, but so far that decision making doesn’t reflect a determination to control how much fossil fuel gets burned and thus how much climate change gets imposed on the world. Decarbonization requires large scale political change and the relevant criterion for evaluating our individual behaviour is whether it is promoting or impeding that transition.

Dr. King then goes on to talk about sea level, challenging my prior claim that there are “centuries of experience that the sea level is always at more or less the same height”. Oddly, he then includes a chart that directly supports my point. It shows sea level going back to 1880, and shifting from about 125 mm below the zero axis to about 50 mm above. Compared to what is being induced by us melting the Greenland and West Antarctic ice sheets, the variation he shows is trivial. As described in the sea level rise portion of the U of T divestment brief: “A 2009 Science article examined the relationship between atmospheric CO2 concentrations and ice sheet stability. The paper identifies how the last time global CO2 concentrations were at current levels, global temperatures were between 3 ˚C and 6 ˚C hotter and sea levels were ’25 to 40 meters higher than at present’.” Expected sea level rise resulting from business-as-usual fossil fuel use is of the order of 1 m to much more: well outside the scope of what anatomically modern humans have experienced, and certainly way beyond what our present-day seafront infrastructure was built for.

Dr. King doesn’t provide much of a response to my using David MacKay’s book as evidence that there is enough renewable and fission energy available to more than replace our current fossil fuel use. In the same paragraph, he argues that somehow the creation of hydrogen-powered airliners is a critical missing part of decarbonization. First, I don’t assume that people will or should be able to fly anywhere near as much as they currently do. Second, I make clear in my post that decarbonization is a progressive process that needs to begin with the fossil fuel use that’s easiest to eliminate before moving to the harder stuff. If you want to keep using them, planes and rockets need energy dense fuel so they’re both part of the hardest to shift portion of our emissions. I would be happy to see air travel become much rarer and more expensive, and accept that such a shift is probably a necessary part of our overall decarbonization effort.

On raw materials, Dr. King says:

Petrochemicals represent a treasure trove of stored chemical energy that simply cannot be replaced given our current scientific knowledge and energy systems.

I wasn’t saying that replacing fossil fuels will be easy. I have been consistent in saying it’s one of the greatest challenges humanity has ever faced and it’s far from clear whether we will manage it. That said, there is no basis for saying that fossil fuels are an irreplaceable raw material. If their precursors could be made by plants out of air and sunlight we can do the same thing: quite possibly at a smaller scale than today’s petrochemical-fed industries and at a higher cost, but again I accept that many things in a low carbon future will be rarer and more costly than they are now.

It might affect Dr. King emotionally to know that I have actually done a lot personally to reduce my fossil fuel dependence and contribution to climate change. I have structured my life so that I can do everything essential on foot: easily able to walk to work and to complete necessary errands. At times, I go weeks at a time without even taking public transit. I have never had a driver’s license or owned a car. I last flew in 2007 and the last time I visited my family and hometown was in 2009/10 by Greyhound, which we calculated would be substantially less greenhouse-gas intensive than flying. I live in a single room on a floor shared by three people. I don’t bring this stuff up in response to hypocrisy allegations because I think the whole ‘only someone who doesn’t use fossil fuels can or should call for decarbonization’ is logically unsound. It’s perhaps worth mentioning here in response to Dr. King’s argument that only people who have chosen to greatly reduce their footprint can know what sort of future they are calling for. I think I have such an idea and, if the alternative is imposing the kind of massive threat that we currently are on people in the future and non-human nature, I think those sacrifices and more are not only acceptable but mandatory.

The emotional tone of Dr. Blair’s post is a bit exasperating in that he seems to think that his level of contempt toward the caricature he has developed of me is itself somehow an argument. He and his supporters have gotten into a big huff because I blocked him on twitter. This easily bleeds into the utterly indefensible argument that anyone who you care to talk to has the obligation to listen to you, and to do so on a platform of your choice (brilliantly lampooned by XKCD). As most people now seem to accept, twitter is a pretty awful place made marginally more tolerable by the ability to block people. I routinely encounter climate change deniers and twitter users who don’t even try to respond to substantive arguments but who simply hurl abuse. If I didn’t block them, they would dominate my timeline. Furthermore, I think I have every right to block people whose tweets I don’t want to see: a category that still includes Dr. King and the other twitter users who took a personally interest in the matter of this banning who followed on after him in arguing that blocking him was very, very wrong.

Another basic error in Dr. King’s post shows in the title: “When political scientists do environmental science the results are not always pretty”. The question of what we ought to do in response to climate change certainly requires science to answer. We need to know how much warming will result from how much coal, oil, and gas burning and what consequence a given level of warming will have for humanity and the rest of nature. Actually deciding what to do, however, goes well beyond environmental science to incorporate politics, economics, and most fundamentally ethics. Condemning people in the future for thousands of years to live in a world which we destabilized and degraded through our selfish use of fossil fuels is a profoundly immoral choice. If we’re not going to make it, we need to stop producing new fossil fuel production, transport, export, and use architecture in rich and highly polluting places like Canada and then play a determined and good faith role in spreading climate-safe energy technologies globally. That’s not the “Chinese Communist Party and Russia’s Vladimir Putin” view, as Dr. Blair rather childishly alleges. That’s survival politics in the 21st century. The alternative is not to keep the cozy fossil-dependent world we have now, but see how rich and prosperous we can remain as devastating global change is making large parts of the planet uninhabitable and huge numbers of people start fighting over what’s left.

Search Canada’s Parliamentary record

Tanya Whyte, one of my classmates at U of T, has been integrally involved in setting up Lipad: a searchable online database of everything said in Canada’s Parliament since 1901.

It’s sure to be valuable to everyone from elementary school students researching projects to academic researchers, journalists, and politicians.

There was a segment about it on TVO yesterday: Every Parliamentary Word Ever Spoken.

Incidentally, it seems that perhaps the first reference to climate change in Parliament was Cyril Lloyd Francis (Liberal) in 1974. Admittedly, it doesn’t discuss anthropogenic climate change, but simply the possibility that the climate will revert of its own accord to something less accommodating for humanity. Nonetheless, some of the predicted consequences align with what we now expect from continuing with unfettered fossil fuel burning.

Online romance

I have seen it argued in several places that among heterosexuals romance is a more egalitarian game for women than for men, with most women being able to find a partner, get married, and have children if they prioritize those things, while the least attractive men struggle to find anyone at all who wants them as a partner.

This is substantiated somewhat in a recent Economist briefing about online dating. They note:

Men on Tantan, he says, tend to like about 60% of all the female profiles they see, but women like just 6% of the male ones. The least attractive women receive similar levels of attention to the most attractive men, says Mr Wang; all can find someone reasonably attractive. Men at the bottom of the ladder end up completely matchless. This fits with the work by Ms Bruch and Mr Newman. In general, both men and women concentrate on people that the common opinion of the site rates as 25% more attractive than they are. Even for women not seen as desirable, that can work. For the least desirable men, nothing works. “I don’t expect that final 5% to be that easy to help,” says Mr Wang.

There’s bad news for women as well. Whereas men actually become more attractive as they age from 20 to about 45, women peak in attractiveness at the youngest end of the scale and decline gradually until about 65.

All told they make the case that online romance is a very good thing, giving everyone the opportunity to efficiently contact a wide range of partners, and being especially helpful for people who are looking for relatively rare characteristics. They note that 70% of same-sex relationships now begin online.

Subject-specific databases

One of my main strategies for organizing information is to create databases for subjects of interest. I’m using the term in the broad Wikipedia sense of “an organized collection of data, stored and accessed electronically” here, and it includes everything from a single folder where PDF versions of all the references cited in a particular monograph of mine are stored to financial tracking spreadsheets, records of my weight, and sets of original RAW files for my photoshoots.

So far for my PhD research I have set up a few:

  • A spreadsheet of all accredited Canadian universities, with pertinent information about each divestment campaign I have identified
  • A master timeline for significant events in all campaigns, as well as events relevant to university divestment that happened in other institutions, like municipalities
  • A list of all scholarly work about university divestment campaigns, including which school(s) the authors looked at
  • A spreadsheet with titles and links to common document types at many campaigns, including detailed petitions like our ‘brief’, recommendations from university-appointed committees, and formal justification for university decisions
  • The consent database specified in my ethics protocol, which has also been useful for keeping tabs on people who I’m awaiting responses from
  • (Somewhat embarrassingly) A Google sheet where I manually tally how long each MS Word chapter draft is at midnight each day

For my earlier pipeline resistance project I had started putting together a link chart of relevant organizations and individuals, as well as a glossary and timeline.

I would love to have more formal training (and ideally coding ability) for working with more flexible kinds of databases than spreadsheets. That would be useful for debugging WordPress MySQL issues, but more importantly for more fundamental data manipulation and analysis. I haven’t really coded (aside from HTML and LaTeX) since long-passed days of tinkering with QBASIC and Pascal during the days of my youth in Vancouver. It seems like it would make a lot of sense to learn Python as a means of building and playing around with my own SQL databases…
