Frontier justice

In other depressing news, there are apparently two Americans: Daniel Strauss and Shanti Sellz, who are being charged for transporting three illegal migrants trying to cross the US-Mexico border to a hospital, when they were dying of thirst. They face up to 15 years in prison and $500,000 in fines.

Legally, the case seems quite clear cut. The defence of necessity allows you to break the law when doing so serves some over-riding purpose. Someone with a suspended license can drive their critically injured child to the hospital, then get off the charge of violating the suspension by claiming that is was necessary to avert a far greater evil. Preventing three people from dying in the desert obviously overrides questions about the legality of assisting those attempting to migrate illegally.

What is most ironic is that the people prosecuting this case would almost certainly defend themselves as Christians – given that the prosecution can only be motivated by a desire for political point-scoring, and not being religious in America is politically suicidal. For would not Jesus himself have argued that if you come across a man dying of thirst in the desert, it is your Christian duty to report him to the proper authorities?

It amazes me that neighbouring democratic states with an increasing number of economic and institutional connections can nonetheless completely fail to accord the most basic ethic of due consideration to each other’s citizens. The prosecutors should be ashamed of themselves, and these charges should be summarily dismissed.

PS. Amnesty International has a campaign on this.
It is also being discussed on MetaFilter.

Violence around Israel

As is so often the case, it is only with the greatest of dismay that one can read headlines from the Middle East at the moment. What baffles me is that I cannot see what anyone hopes to gain from this looming conflict. Kidnapping Israeli soldiers is a good way to provoke massive retaliation (or provide justification for attacks planned before the kidnapping). At the same time, what Israel really hopes to achieve through incursions into Gaza and Lebanon is unclear. Almost certainly, there actions are further imperiling the hostages. The only comprehensible reasoning I can come up with is that the Israelis fear that anything less than a massive response to these kidnappings would encourage more.

The prospect of large-scale violence in the region, including considerable loss of life, is increasingly real. I am suspect that covert diplomatic efforts are being made on the part of the United States and others to urge greater restraint upon Israel, though a public condemnation seems pretty unlikely.

The only possible solution in the region is normalized relations between Israel, its neighbours, and a viable Palestinian state comprising the great majority of the West Bank and Gaza. The prospects of that point being reached are in the process of receding far off into the distance. And we can really do is hunker down for more bloodshed, while watching the oil producing nations (including Canada) rub their hands together in greedy anticipation of the further windfall from turmoil-boosted prices ahead.

Scotland prep: boots and midges

Whenever I mention the upcoming Scotland hiking trip, talk rapidly turns to the Scottish Highland Midge (Culicoides Impunctatus). From everything I have read, the end of July is definitely high season for midges, and these aggressive creatures can be maddening. Does anyone have experience with dealing with these insects? I plan to equip myself with high DEET spray before I leave, though I am of two minds about the wisdom of purchasing an actual midge net. Supposedly, their concentrations vary a great deal by region. Our plan is as follows:

[W]e’re camping at Shiel Bridge (grid reference NG 938 186) (rather than near Invergarry as originally planned). This should be a wonderful base, located between Loch Duich, leading out towards Loch Alsh and the Isle of Skye, and Glen Shiel, site of the Battle of Glen Shiel in 1719. Glen Shiel itself is lined with Munros, including some of the finest hills in the Western Highlands. These include the classic Five Sisters of Kintail and the South Shiel Ridge, so we’ll be spoilt for choice!

In spite of anticipated midge problems, I am very excited about this trip. I’ve been wearing my hiking boots all day, with the aim of re-acclimatizing to them after a year in trainers. A great deal of joy can be extracted from torsional rigidity and ankle support. Despite being ankle-high, my boots are actually cooler feeling than my trainers. The people at MEC knew what they were talking about when they said that Gore-Tex shoes, while good in the wet, become excessively hot fairly easily.

PS. I will post a conversion of the coords above to UTM or DMS as soon as I can find a script that will deal with the UK grid.

[Update]: Converting from UK national grid to anything else is a huge pain. Not only does it have its own zero coordinates and uniquely sized zones, but it is based on a different datum from more familiar coordinate systems. You can read all about it, if you like.

On self-representation

Milan in the mirror

Every photographer understands the impetus behind the self-portrait: not some formal tripod and time-delay creation, but the quasi-accidental inclusion of oneself in a composition, in the form of a shadow, perhaps, or a reflection.

Photography is a curious art-form, for many reasons. Unlike most forms of artistic representation, it requires relatively little ability to translate sight into the moment of a hand. Instead, it required just one firm touch upon a button, under conditions that are recognized as being correct. The difficulty of affirming the originality of that act may partially explain the motivation behind the photographer’s self-portrait.

Mostly, however, I think of it as a playful interchange between photographer and observer. Whereas the two are normally in a conspiracy with regards to the subject (at the same time as the photographer and the subject are in conspiracy against the observer), in this case, there is a kind of simultaneous mutual revealing, which is very artistically and emotively interesting.

On password security

I was talking with Kelly today about passwords, and how they are a fundamentally weak form of security. Supposedly, we are all meant to have different passwords for every site, so that one database being compromised by an external hacker or malicious insider won’t lead to our email and other sites being at risk. Also, we are supposed to use long and complex passwords with case-changes, numbers, punctuation, etc. (Think ‘e4!Xy59NoI2’) Together, these two requirements far exceed the capability of most human beings.

The real solution is to back up passwords with something else, so that they don’t need to be so strong. This is called two-factor authentication, and it could include something like a smart card that people carry and slot into computers along with a password so as to authenticate themselves. This is already used in cars. Inside the key or newer cars is a little chip with a radio antenna. When you try to use the key to start the car, a radio message is broadcast by the car. The chip detects it, does a bit of thinking to generate a response that authenticates the key, and re-broadcasts it. Using both the physical profile of the key and the radio challenge-response authentication system, attacks based on picking locks or freezing and cracking the cylinder inside them can be circumvented. The system obviously isn’t impossible to foil, but it is substantially more difficult in relation to the additional cost.

In the computer context, such two-factor authentication could take other forms: for instance, a little card that listens to a series of tones from an external source (over the phone, or from a computer), passes them through an algorithm and emits a series of tones in response to authenticate. This is just doing with audio what a smart card does with electricity. Ideally, the second factor would be like a credit card, in that you could have it cancelled and re-issued in the event that it is lost or stolen, immediately disabling the missing unit.

Until such a system emerges, it seems sensible to have tiers of passwords. I have two really weak passwords for things that I sometimes share with close friends. Then, I have a password for low-risk sites where there is no real harm that can come from my account being compromised. Then, I have a cascade of ever-stronger passwords. Something like LiveJournal has a pretty strong password, because it would be a pain if somebody took it over. The general vulnerabilities of passwords are:

  1. Someone could guess it (either manually or with a brute force attack)
  2. Someone could watch you type it in
  3. Someone could install a hardware or software keystroke logger on a machine where you enter it
  4. Someone could break into a database that contains it, then try using it on other sites you use
  5. Someone could extract it from a program on your computer that stores them in an insecure way (like Windows screen-saver passwords, which can be learned using a simple program)

Most of these require physical access to a machine that you use. I would guess that the most common of these is number four. Given that most people use the same password for everything, some underhanded employee at your ISP or webmail provider could probably grab it pretty easily, as well as information on other sites you use. (Hashing algorithms are one way this risk can be mitigated, on the server side, but that’s a discussion for another day).

At the top level, there are things that demand a really strong password: for instance, webmaster control accounts or anything connected to money. For these, I use random alphanumeric strings of the maximum permitted length, never re-using one and changing them every month or so.

Obviously, I cannot remember these for several banks and websites. As such, I write them down and guard them. I am much better at guarding little bits of paper than at remembering random strings of data. I regularly carry around little bits of paper worth tens of Pounds, and little bits of plastic worth thousands of Pounds, if only until disabled. Indeed, I have been guarding bits of paper for well over a decade.

On fundamental physics

Grafitti near the Oxford CanalWatching this video about the Large Hadron Collider (a particle accelerator under construction at CERN), I was reminded of something I was wondering about a few weeks ago. People talk about the universe being the size of a grain of sand, or the size of a marble, in the moments immediately following the big bang. That seems comprehensible enough, but there is a fundamental problem with the analogy. The marble sized thing isn’t just all the mass in the universe, expanding into space that existed prior to the ‘explosion.’ Instead, space and time were supposedly unfurling simultaneously.

The big question, then, is how it can be said that it was expanding at all? If there was nothing to expand into, how is this process of explosion something that is comprehensible, as such? To imagine it requires a perspective where the camera is outside our universe, an idea that invalidates the notion that the big bang was the origin of our universe. And, even if our universe is embedded in a higher dimensional space, the emergence of our lower-dimensional realm still requires some explanation. I wonder if it will ever become an object of knowledge for us: both as a species with a certain amount of information about how the universe works – verified through repeated experiments and predictive power – and as a collection of individuals who almost never know more than a tiny fraction of what all people know as a collective.

The video is a bit over-hyped, as well as a transparent attempt to defend spending a great deal of money on pure research, but perhaps it will interest some people regardless. Some of the prospects associated with the LHC – such as looking for evidence of supersymmetry or investigating the nature of gravity – are very exciting indeed, from the perspective of advancing our basic understanding about the nature of matter, and the kinds of interaction that take place in our universe.

Heading South

In a number of ways, Heading South is a film that reverses expectations and thereby leads you to question the ways in which an issue is understood. The film is essentially about sex tourism, though the clients are aging women rather than the middle-aged men who would probably be demonized in the standard documentary treatment of the subject. While such condemnation may well be deserved, it doesn’t attach itself so easily in this case. The tensions between the women, and the insecurities within them, provide the dramatic energy that drives this frequently provocative film. The most interesting scenes are a series of confessional sketches, in which different characters direct monologues at the camera. The decision to employ such a technique highlights the quasi-documentary quality of the film.

Primarily in French, with subtitles, the film may appeal to those who know some French and are concerned about having it slip away from them (this is the case for almost everyone I know who was in French immersion.) The portrayal of Haiti under the Duvalier regime of the 1970s is powerful but indirect, consisting largely of a few vignettes showing the lives of people subjected to arbitrary power.

Morally complex and artfully produced, Heading South is a film to see when you want something to think about.

Tea

One unexpected stop in London yesterday was The Tea House, near Covent Garden (15 Neal Street, WC2). Sarah and I were lured in because the shop was incredibly fragrant. The same can be said of the 150g of Chai which I purchased there, and which has markedly increased the pleasantness of the smell of my room, just by virtue of sitting there in its bag. Their licorice tea, which Sarah got and which we tried after dinner, was also quite good. The secret, I think, was keeping the level of tea flavour low enough that it complemented, rather than overwhelmed, the distinctive flavour of dried Camellia Sinsensis. There is also much to be said for a shop that unfailingly demonstrates a commitment to the fact that only drinks made with an infusion based on Camellia Sinsensis are deserving of the descriptor ‘tea.’ Rose hips and the like may taste good in boiled water, but they are not tea.

Frequently as I am accused of being a coffee addict, I confess to preferring the aesthetics of tea. Coffee is a working person’s drink – to be consumed out of big paper cups while walking purposefully down a sidewalk, or gulped down from a big mug during a coffee break. Tea is more versatile and, to my way of thinking, more relaxed. As such, a break focused on its consumption is more worthy of that title.

Such talk makes me think nostalgically back to the days of the Esteemed Afternoon Tea Society. For those unfamiliar with this most absurd and memorable of UBC clubs, see the Epic History and the Declaration of War (PDF), which formally began the life of the organization as a potent (and generally highly militant) force on campus.

Quick London summary

Stairs at Sommerset HouseHappy Birthday Nora Harris

Today’s trip to London was very successful: I got to spend time with Sarah for the first time since her wedding, I saw a large number of new Kandinsky paintings at the Tate Modern exhibition (including the spectacular Composition VI), I saw the Haitian film Heading South at an arty theatre in Soho, and had a number of tasty meals. Meeting Sarah’s husband Peter for the third time, as well as her father again, was also excellent.

Sarah and I saw some of the artwork at Somerset House: another London institution that I had previously known nothing about that turns out to be well-stocked with Gauguin, Matisse, Picasso, and such. They even had a respectable collection of Kandinsky paintings – organized in an identical thematic fashion to the Tate Modern exhibition.

I had seen Kandinsky’s work first-hand before: in New York in 2003, both at the Guggenheim and at the Museum of Modern Art. Of course, their new location had not yet opened at that point, so they were only showing a limited assortment out in Queens. By comparison, the Tate Modern exhibition was a much more comprehensive look into the progression of his work. Of all the paintings there, the massive canvas of Composition VI was most interesting and compelling. I urge people not to search for it online, because on the basis of my previous viewings of it as some little JPEG file, I can assure you that it cannot be understood in that format. You need to see the wall-sized painting to have any comprehension of it at all.

While the trip really deserves more ample description, it is 2:00am. I will do so soon.

Fish paper publication upcoming

I may be delerious because it’s 6:30am, but this seems pretty unambiguous:

I really enjoyed the piece you wrote on EU policies regarding fishery sustainability off the coast of West Africa. I’d like to work with you to prepare your piece for publication in [the MIT Internatinal Review].

You mentioned on your cover letter that you would be willing to “re-focus it in the most appropriate direction and summarize other sections.” This will probably comprise the bulk of our work together, as your piece was very well written to begin with.

An excellent bit of news by which to start the day. I am off to London.
