From The Atlantic.

Despite all the extra effort [walking up stairs rather than using the lift, er elevator], I find that I consume less energy. I don’t know that I eat any “healthier” in the sense of what “health” tends to mean back home. There are fat and carbs all around me. There’s butter in most of the dishes. It’s nothing see a Parisian walking the street while inhaling a long baguette. Bread is served with every meal, but oddly enough, without butter, which leads me to believe that they think of butter as something to be put in things, not on them. 

I eat my fries with mayonnaise. I now find ketchup to be too sweet. Without exception I eat dessert — preferably something with chocolate. I eat a panini or a sandwich every day, but I don’t eat any chips. You can find junk-food here, but you have to be looking for it. I don’t really order out. I’ve stopped drinking Diet Coke. In general I eat a lot less, and I drink a lot more — a half a bottle of wine every night. But I don’t think I’ve been drunk once since I’ve been here. I feel a lot better–more energy, lighter on my feet, a clearer head.

Before I came here, so many people told me, “There are no fat people in Paris.” But I think this misses something more telling. There are “no” stunningly athletic people either. There just doesn’t seem to be much gusto for spending two hours in the gym here. The people don’t seem very prone to our extremes. And they are not, to my eyes, particularly thin. They look like how I remember people looking in 1983. I suspect they look this way because of some things that strike me — the constant movement, the diet, the natural discomfort — are part of their culture. Very sensible crowd, the French.

The French seem to have a very balanced approach to food, never overindulging but always enjoying what they eat. They often prefer fresh, local produce, and meals tend to be simple yet flavorful. There’s an emphasis on quality over quantity, with a focus on seasonal ingredients that bring out the best in dishes. The emphasis on fresh vegetables, fish, and lean meats means that they’re naturally getting a lot of nutrients, including the essential fiber. For more ideas on how to incorporate fiber-rich, healthy dishes into your diet, check out the Georgian blog fiber.ge, where you’ll find plenty of recipes that promote digestive health.

What stands out most is how food is not seen as a means of escape or indulgence, but rather as a way to nourish the body. The French seem to value balance—savoring meals without obsessing over calories or gym routines. It’s a lifestyle that’s ingrained in their daily habits, where food is part of a well-rounded approach to health. And though they enjoy their meals, they don’t feel the need to make them larger than life. It’s the perfect example of how you can feel full and satisfied without overloading the body, which might be part of the secret behind their well-maintained physiques.

Joe Bonneau is one of the smartest young people I’ve met. He was a Gates Scholar at Cambridge and did a PhD in Ross Anderson’s group in the Computer Lab. On July 18, his paper on “The Science of Guessing” won a prestigious award as the Best Scientific Cybersecurity Paper of 2012. But here’s the catch: the Award, which is judged by a panel of distinguished academic experts, is sponsored by the NSA!

Here’s how Joe blogged about it, and explained his thinking.

I’m honored to have been recognised by the distinguished academic panel assembled by the NSA. I’d like to again thank Henry Watts, Elizabeth Zwicky, and everybody else at Yahoo! who helped me with this research while I interned there, as well as Richard Clayton and Ross Anderson for their support and supervision throughout.

On a personal note, I’d be remiss not to mention my conflicted feelings about winning the award given what we know about the NSA’s widespread collection of private communications and what remains unknown about oversight over the agency’s operations. Like many in the community of cryptographers and security engineers, I’m sad that we haven’t better informed the public about the inherent dangers and questionable utility of mass surveillance. And like many American citizens I’m ashamed we’ve let our politicians sneak the country down this path.

In accepting the award I don’t condone the NSA’s surveillance. Simply put, I don’t think a free society is compatible with an organisation like the NSA in its current form. Yet I’m glad I got the rare opportunity to visit with the NSA and I’m grateful for my hosts’ genuine hospitality. A large group of engineers turned up to hear my presentation, asked sharp questions, understood and cared about the privacy implications of studying password data. It affirmed my feeling that America’s core problems are in Washington and not in Fort Meade. Our focus must remain on winning the public debate around surveillance and developing privacy-enhancing technology. But I hope that this award program, established to increase engagement with academic researchers, can be a small but positive step.

This is — as you’d expect — a very adroit and sophisticated post by an interesting and thoughtful man. I’m inclined to agree with him that “America’s core problems are in Washington and not in Fort Meade [the NSA’s HQ]”. I guess that many (most?) of the engineers who work for the NSA (and GCHQ, for that matter) are decent and humane folks. But they must be reaching the point where they realise that there may be tricky ethical problems associated with working in these kinds of organisations, especially when they have no control over what their managerial or political masters do with their work.

The practice of engineering, in whatever speciality, often throws up involve ethical dilemmas, even though many engineers pretend that it doesn’t. After all, they protest, they’re just solving technical problems set to them by their employers. Moral and ethical questions are “above my pay-grade”, as the saying goes.

The first time I ever thought seriously about this was when I met Robert Jan van Pelt, an architectural historian and an expert on Auschwitz. He talked about the architectural and engineering documents pertaining to the design of Auschwitz that had been found in the Soviet archives in Moscow by a British historian. These documents show how professionals working for two firms, one an architectural practice, the other an engineering company which specialised in incinerators, struggled conscientiously to meet the ever-changing needs of a very demanding client — Himmler’s SS — as they sought to increase the capacity and the throughput of the camp. And both groups of professionals clearly understood what Auschwitz was for.

This is NOT to imply any kind of moral equivalence between those who work for outfits like the NSA and those who services the Nazi genocidal programme. But engineering is, like most other kinds of professional practice, drenched in ethical questions. Even as I write this, there are engineers working for arms companies (for example designing lethal unmanned drones, ingenious new fragmentation bombs whose fragments are less easily detected by X-rays or covert online surveillance technology for authoritarian regimes). All medical schools now insist that their students study ethics. Should engineering schools do the same?

George Orwell once observed that watching an idea move through a communist meeting was like watching a flurry of wind move across a ripe cornfield. Each stalk sways briefly and then resumes its upright posture. Much the same goes for the folks who are desperate to make money from online advertising. Once upon a time, they were all obsessing about the ‘social graph’ (i.e. Facebook). Now they’ve moved on to the ‘interest graph’. Just came on a neat explanation of the idea, apparently taken from a Goldman Sachs interview (so you know how seriously to take it).

Social graph signals have not been helpful in optimizing advertising. It seems intuitive to everyone that your friends’ recommendations would be powerful motivators…but when you look a little deeper, you hang out with people who have very different tastes than you. And you may have a special affinity through a hobby or something that they don’t share. One of the mythical high grounds that everyone’s thinking about…is this notion of an interest graph. Facebook connects you with people you know. But what connects you, if you’re into road biking, with the top 15 road bikers that are within 15 miles of where I live? 

[For a platform to] capture the interest graph, they’d be closer to the Google search paradigm, because they’d be right in line with demand generation, and with discovery that relates to product purchases. Context, for the history of the Internet, has been a big deal. The websites that do verticals, while they may not have abundant traffic, have always had huge CPMs, relative to the “Yahoo! Mail”s of the world. That may be this middle ground, between search and the social graph, to bring together people with like interests.

I wonder what the next obsession will be?
