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?

As I watched the Twin Towers collapse on September 11, 2001 I wrote this in my diary: “We can kiss goodbye to civil liberties from this day onwards. There’s nothing that democracies won’t do to prevent this ever happening again”. As ever, John Perry Barlow was both more articulate, and more perspicacious. This is what he wrote that day to those on his BarlowFriendz list. (Courtesy of SpiekerBlog.)

This morning’s events are roughly equiv­a­lent to the Reich­stag fire that pro­vided the social oppor­tu­nity for the Nazi take-over of Ger­many.

I am not sug­gest­ing that, like the Nazis, the author­i­tar­ian forces in Amer­ica actu­ally had a direct role in per­pe­trat­ing this mind-blistering tragedy. (Though their indi­rect role deserves a much longer dis­cus­sion.)

Nev­er­the­less, noth­ing could serve those who believe that Amer­i­can “safety” is more impor­tant than Amer­i­can lib­erty bet­ter than some­thing like this. Con­trol freaks will dine on this day for the rest of our lives.

Within a few hours, we will see begin­ning the most vig­or­ous efforts to end what remains of free­dom in Amer­ica. Those of who are will­ing to sac­ri­fice a lit­tle — largely illu­sory — safety in order to main­tain our faith in the orig­i­nal ideals of Amer­ica will have to fight for those ideals just as vig­or­ously.

I beg you to begin NOW to do what­ever you can — whether writ­ing your pub­lic offi­cials, join­ing the ACLU or EFF, tak­ing to the streets, or liv­ing vis­i­bly free and fear­less lives — to pre­vent the spasm of con­trol mania from destroy­ing the dreams that far more have died for over the last two hun­dred twenty five years than died this morn­ing.

Don’t let the ter­ror­ists or (their nat­ural allies) the fas­cists win.

Remem­ber that the goal of ter­ror­ism is to cre­ate increas­ingly par­a­lytic total­i­tar­i­an­ism in the gov­ern­ment it attacks. Don’t give them the sat­is­fac­tion.

Fear noth­ing. Live free.

And, please, let us try to for­give those who have com­mit­ted these appalling crimes. If we hate them, we will become them.

May God — or What­ever you want to call It — bless us all. We’ll need it.

Courage,

John Perry

And here’s what he wrote the other day:

The answer to ter­ror­ism is not fear. Nor is it vio­lence. Nor is it trans­form­ing our coun­try in the very ways Al Queda wished, thus betray­ing every­thing Amer­ica stood for and becom­ing an arbi­trar­ily vio­lent and sur­veil­lant nation that rou­tinely tor­tures per­ceived ene­mies and incar­cer­ates them indef­i­nitely with­out due process.

If only we’d had the courage and self-assurance to say, “Nice shoot­ing, Ass­holes, but we have lots of tall build­ings.” And left it at that. If only we’d had the courage to respond to ter­ror­ism with a stead­fast unwill­ing­ness to be ter­ror­ized. If only we’d rec­og­nized the trap we were being led into. But we didn’t.
Now Amer­ica is a par­ody of what it was that day 10 years ago. We have bank­rupted our­selves and slaugh­tered tens of thou­sands with point­less wars of reac­tion. We have gut­ted our enlight­ened guar­an­tees of civil lib­erty and gov­ern­men­tal restraint. We have lost our way. And we have become the very mon­ster Osama bin Laden per­ceived us to be.

This is a sad day indeed. Not merely because it refreshes the tragedies of that ter­ri­ble day, but because it also reminds us of all the tragedies — most of them far worse and more per­ma­nent in effect — that we sub­se­quently inflicted upon our­selves and on count­less inno­cents here and abroad in reac­tion to those events.

Fox-Amphoux roofscape, originally uploaded by jjn1.

Today we went to one of my favourite places in the Var — the tiny hilltop village of Fox-Amphoux. It’s an old Roman village at the intersection of two Roman roads, 540m above sea level with a lovely panoramic view of the surrounding countryside and it’s one of the quietest and most peaceful places I know. It has no shops, one tiny hotel and an artist’s studio. We sat on the steps of the church, in the shade of a nettle tree that is believed to be several hundred years old, and had a delicious picnic.

The village has one claim to fame, though. The clue is in this crude plaque:

It’s the birthplace of Paul de Barras, who was one of the leading figures in revolutionary and post-revolutionary France, and was for four years one of the most powerful men in France. (He was the lead member of the five-man French Directory between 1795 and 1799.)

Given the difficulties of communication at the time, one wonders how much the inhabitants of this place ever knew about their famous son. And whether he ever visited it after he’d gone on to greater things.

Interesting post by George Dyson on The Edge site. Excerpt:

This is much bigger than the relative merits of national security vs. the fourth amendment to the U.S. Constitution, or any of the other debates by which the Snowden revelations have been framed. We are facing a fundamental decision (as Turing anticipated) between whether human intelligence or machine intelligence is given the upper hand. The NSA has defended wholesale data capture and analysis with the argument that the data (and metadata) are not being viewed by people, but by machines, and are therefore, legally, not being read. This alone should be cause for alarm.

And what of the current obsession with cyberterrorism and cyberwar? We should deliberately (and unilaterally if need be) abandon the weaponization of codes and the development of autonomous weapons—two different approaches to the same result. They both lead us into battles that can never be won. A good example to follow is the use of chemical and biological weapons—yes, they remain freely available, but we have achieved an almost universal consensus not to return to the horrors of poison gas in World War I. Do we have to repeat the mistake? We are currently taking precisely the wrong approach: fast-tracking the development of secret (and expensive) offensive weapons instead of an open system of inexpensive civilian-based defense.

Fourteen years ago, I spent an afternoon in La Jolla, California with Herbert York, the American physicist of Mohawk ancestry who became Eisenhower’s trusted advisor and one of the wisest and most effective administrators of the Cold War. York was appointed founding scientific director of ARPA and was instrumental both in the development of the hydrogen bomb and its deployment, in a few short years, by a working fleet of Intercontinental Ballistic Missiles, or ICBMs. He was sober enough to be trusted with the thermonuclear arsenal, yet relaxed enough about it that he had to be roused out of bed in the early morning of July 6, 1961, because he had driven someone else’s car home by mistake.

York understood the workings of what Eisenhower termed the military-industrial complex better than anyone I ever met. “The Eisenhower farewell address is quite famous,” he explained to me over lunch. “Everyone remembers half of it, the half that says beware of the military-industrial complex. But they only remember a quarter of it. What he actually said was that we need a military-industrial complex, but precisely because we need it, beware of it. Now I,ve given you half of it. The other half: we need a scientific-technological elite. But precisely because we need a scientific-technological elite, beware of it. That’s the whole thing, all four parts: military-industrial complex; scientific-technological elite; we need it, but beware; we need it but beware. It’s a matrix of four.”

We are much, much deeper in a far more complicated matrix now. And now, more than ever, we should heed Eisenhower’s parting advice. Yes, we need big data, and big algorithms—but beware.

… in 1947, 1947, President Truman signed the National Security Act, creating the Department of Defense, the National Security Council, the Central Intelligence Agency and the Joint Chiefs of Staff.

“I’m a very responsible guy. I would pay the national debt down first. Then I would buy the Phillies, if I could get a great price.”

— Chris Reynolds, of Media, Pa., on seeing in an email statement that his PayPal balance was $92,233,720,368,547,800 . He was not a quadrillionaire — nor the richest man in the world — for long, however. When he logged on to his PayPal account, his balance read $0. Was someone at PayPal a bit spacey? Perhaps PayPal just has astronomical on the mind: As the Merc’s Heather Somerville wrote last month, the company is working on a payments system for use in outer space. But  back to the big oops. ”This is obviously an error and we appreciate that Mr. Reynolds understood this was the case,” the San Jose company said in a statement, according to CNN. The company, owned by eBay (market capitalization: about $73.8 billion), said it offered to donate money to a cause chosen by Reynolds.

Wonderful series of videos in the French style.

Story from a friend whose daughter recently graduated from a major UK university.

The Vice-Chancellor (or perhaps it was the Chancellor – the distinction between the two is often lost on parents) was making a stirring speech about the importance of knowledge, etc. An example of this was the importance of the great overarching scientific theories. So the great man said, “And Darwin’s theory of…”. At which point he had a Senior Moment. There was a brief pause while he rummaged around for the word. And then out it came: “relativity”.

Could happen to any of us. Well any of us d’une certain age, anyway. I remember overhearing a woman in the Shelbourne Hotel in Dublin once explaining to her friend why her husband’s Volvo was superior to her companion’s husband’s Mercedes. “It’s got a cataclysmic convertor”, she said.
