How to exercise your brain

commonplace book, science / /

From Robyn Williams’s “How to Keep Your Brain Young” (The Science Show: 24 September 2005):

Ian Robertson: Seven steps for keeping your brain functioning optimally when you’re older, but not just when you’re older but throughout life are: One, Aerobic fitness – amazing effects on the brain. Mental stimulation, both general mental stimulation and there are also specific memory and other training exercises you can do. The third one is new learning, learning new skills and new facts. The fourth one is reducing stress; severe stress has poor effects on the brain. The fifth one is diet; a diet that’s high in antioxidants and fresh fruit and vegetables and also fish and low in saturated fats has quite extraordinary effects on the brain. The sixth one is social interaction and a rich social environment. This is correlated with enhanced cognitive function. And finally, think young. Thoughts about age, which may not be justified, can actually influence your behaviour, and by influencing your behaviour perhaps to behave in an old way can thereby have deleterious effects on your brain. …

But that’s what education is all about; it’s about trying to train people to think, trying to train them to use their brain capacity. The trouble is we tend to stop being educated when we’re about in the early 20s, and that may be part of the reason why we see more of a drop off of mental capacity as we get older than we need see. If you keep training your brain – it’s a bit like a vintage car: a vintage car can go as fast as a new car but needs more maintenance. Well that’s true of the vintage brain as well when you’re over 60 or over 50 even.

NSA spying: Project Shamrock & Echelon

history, politics, security, tech in changing society, technology / /

From Kim Zetter’s “The NSA is on the line — all of them” (Salon: 15 May 2006):

As fireworks showered New York Harbor [in 1976], the country was debating a three-decades-long agreement between Western Union and other telecommunications companies to surreptitiously supply the NSA, on a daily basis, with all telegrams sent to and from the United States. The similarity between that earlier program and the most recent one is remarkable, with one exception — the NSA now owns vastly improved technology to sift through and mine massive amounts of data it has collected in what is being described as the world’s single largest database of personal information. And, according to Aid, the mining goes far beyond our phone lines.

The controversy over Project Shamrock in 1976 ultimately led Congress to pass the 1978 Foreign Intelligence Surveillance Act and other privacy and communication laws designed to prevent commercial companies from working in cahoots with the government to conduct wholesale secret surveillance on their customers. But as stories revealed last week, those safeguards had little effect in preventing at least three telecommunications companies from repeating history. …

[Intelligence historian Matthew Aid] compared the agency’s current data mining to Project Shamrock and Echelon, the code name for an NSA computer system that for many years analyzed satellite communication signals outside the U.S., and generated its own controversy when critics claimed that in addition to eavesdropping on enemy communication, the satellites were eavesdropping on allies’ domestic phone and e-mail conversations. …

If you want some historical perspective look at Operation Shamrock, which collapsed in 1975 because [Rep.] Bella Abzug [D-NY] subpoenaed the heads of Western Union and the other telecommunications giants and put them in witness chairs, and they all admitted that they had cooperated with the NSA for the better part of 40 years by supplying cables and telegrams.

The newest system being added to the NSA infrastructure, by the way, is called Project Trailblazer, which was initiated in 2002 and which was supposed to go online about now but is fantastically over budget and way behind schedule. Trailblazer is designed to copy the new forms of telecommunications — fiber optic cable traffic, cellphone communication, BlackBerry and Internet e-mail traffic. …

Echelon, in fact, is nothing more than a VAX microcomputer that was manufactured in the early 1970s by Digital Equipment Corp., and was used at six satellite intercept stations [to filter and sort data collected from the satellites and distribute it to analysts]. The computer has long since been obsolete. Since 9/11, whatever plans in place to modernize Echelon have been put on hold. The NSA does in fact have a global intercept network, but they just call it the intercept collection infrastructure. They don’t have a code name or anything sexy to describe it, and it didn’t do domestic spying.

Transcendence, described by the East & West

language & literature, religion / /

From Steve Paulson’s “The disbeliever” (Salon: 7 July 2006):

But it does raise the question, what do you mean by spiritual? And what do you mean by mystical?

By spiritual and mystical — I use them interchangeably — I mean any effort to understand and explore happiness and well-being itself through deliberate uses of attention. Specifically, to break the spell of discursive thought. We wake up each morning, and we’re chased out of bed by our thoughts, and then we think, think, think, think all day long. And very few of us spend any significant amount of time breaking that train of thought. Meditation is one technique by which to do that. The sense that you are an ego, busy thinking, disappears. And its disappearance is quite a relief.

Well, it’s interesting to hear this description of mysticism because I don’t think that’s how most people would see it. I mean, most people would play up the more irrational side. Yes, you’re losing yourself, but you’re plunged into some larger sea of oneness, of perhaps transcendent presence. Obviously, you’re staying away from that whole supernatural way of thinking.

Well, it’s very Buddhist of me to do that. The Buddhists tend to talk in terms of what it’s not. They talk about it being no self, they talk in terms of emptiness. But the theistic traditions talk in terms of what the experience is like. There, you get descriptions of fullness and rapture and love and oneness.

Religious moderates legitimize fundamentalism

From Steve Paulson’s “The disbeliever” (Salon: 7 July 2006):

In perhaps his most daring rhetorical gambit, Harris seeks to undermine religion by denouncing not just jihadis and fundamentalists, but moderates. “Religious moderates are, in large part, responsible for the religious conflict in our world,” he writes, “because their beliefs provide the context in which scriptural literalism and religious violence can never be adequately opposed.” Harris especially chastises moderates for refusing to criticize scripture-quoting extremists; for him, they are basically guilty of legitimizing fundamentalism. …

A private espionage company for businessmen

business, security, technology / /

From Bo Elkjaer and Kenan Seeberg’s “Echelon’S Architect” (Cryptome: 21 May 2002):

After that, [Bruce McIndoe] started to design Echelon II, an enlargement of the original system.

Bruce McIndoe left the inner circle of the enormous espionage network in 1998, a network run by the National Security Agency, the world’s most powerful intelligence agency, in cooperation with other Western intelligence services. Ekstra Bladet tracked down Bruce McIndoe to IJet Travel Intelligence, a private espionage agency where he is currently second in command.

IJet Travel Intelligence is an exceedingly effective, specialized company that employs former staff members of the NSA, CIA, KGB and South African intelligence services.

The company’s task is to furnish reports for top executives from US business and industry that reveal everything about the destination to which they are travelling for their multinational company. All the information they need to make the trip as safe as possible. The company resembles a miniature version of his previous employer, the world’s most powerful intelligence agency, the NSA. …

“Okay. In short, we have transferred everything I did for the NSA and other services to a private company that then sells intelligence to businesspersons. We get information on everything from local diseases, outbreaks of malaria epidemics and local unrest to strikes, the weather and traffic conditions. Our customers are large multinational companies like Prudential and Texas Instruments. We also work for institutions like the World Bank and the IMF.” …

“Yes, exactly. Our staff are also former intelligent agents who have either developed or run espionage operations for US intelligence agencies or people from the UK, South Africa and Russia.”

What should one study in college as an undergraduate?

education / /

From Paul Graham’s “Undergraduation” (March 2005):

The social sciences are also fairly bogus, because they’re so much influenced by intellectual fashions. If a physicist met a colleague from 100 years ago, he could teach him some new things; if a psychologist met a colleague from 100 years ago, they’d just get into an ideological argument. Yes, of course, you’ll learn something by taking a psychology class. The point is, you’ll learn more by taking a class in another department.

The worthwhile departments, in my opinion, are math, the hard sciences, engineering, history (especially economic and social history, and the history of science), architecture, and the classics. A survey course in art history may be worthwhile. Modern literature is important, but the way to learn about it is just to read. I don’t know enough about music to say.

You can skip the social sciences, philosophy, and the various departments created recently in response to political pressures. Many of these fields talk about important problems, certainly. But the way they talk about them is useless. For example, philosophy talks, among other things, about our obligations to one another; but you can learn more about this from a wise grandmother or E. B. White than from an academic philosopher. …

Language courses are an anomaly. I think they’re better considered as extracurricular activities, like pottery classes. They’d be far more useful when combined with some time living in a country where the language is spoken. On a whim I studied Arabic as a freshman. It was a lot of work, and the only lasting benefits were a weird ability to identify semitic roots and some insights into how people recognize words.

Studio art and creative writing courses are wildcards. Usually you don’t get taught much: you just work (or don’t work) on whatever you want, and then sit around offering “crits” of one another’s creations under the vague supervision of the teacher. But writing and art are both very hard problems that (some) people work honestly at, so they’re worth doing, especially if you can find a good teacher.

Learn by working on hard problems

From Paul Graham’s “Undergraduation” (March 2005):

Thomas Huxley said “Try to learn something about everything and everything about something.” Most universities aim at this ideal.

But what’s everything? To me it means, all that people learn in the course of working honestly on hard problems. …

Working on hard problems is not, by itself, enough. Medieval alchemists were working on a hard problem, but their approach was so bogus that there was little to learn from studying it, except possibly about people’s ability to delude themselves.

Education teaches people how to solve problems, not choose the good ones

business, education, history / /

From Paul Graham’s “Why Smart People Have Bad Ideas” (April 2005):

Why did so few applicants really think about what customers want? I think the problem with many, as with people in their early twenties generally, is that they’ve been trained their whole lives to jump through predefined hoops. They’ve spent 15-20 years solving problems other people have set for them. And how much time deciding what problems would be good to solve? Two or three course projects? They’re good at solving problems, but bad at choosing them.

But that, I’m convinced, is just the effect of training. Or more precisely, the effect of grading. To make grading efficient, everyone has to solve the same problem, and that means it has to be decided in advance. It would be great if schools taught students how to choose problems as well as how to solve them, but I don’t know how you’d run such a class in practice.

Business, work, and good ideas

From Paul Graham’s “Why Smart People Have Bad Ideas” (April 2005):

This summer, as an experiment, some friends and I are giving seed funding to a bunch of new startups. It’s an experiment because we’re prepared to fund younger founders than most investors would. That’s why we’re doing it during the summer– so even college students can participate. …

The deadline has now passed, and we’re sifting through 227 applications. We expected to divide them into two categories, promising and unpromising. But we soon saw we needed a third: promising people with unpromising ideas. …

One of the most valuable things my father taught me is an old Yorkshire saying: where there’s muck, there’s brass. Meaning that unpleasant work pays. And more to the point here, vice versa. Work people like doesn’t pay well, for reasons of supply and demand. The most extreme case is developing programming languages, which doesn’t pay at all, because people like it so much they do it for free. …

So why were we afraid? We felt we were good at programming, but we lacked confidence in our ability to do a mysterious, undifferentiated thing we called “business.” In fact there is no such thing as “business.” There’s selling, promotion, figuring out what people want, deciding how much to charge, customer support, paying your bills, getting customers to pay you, getting incorporated, raising money, and so on. And the combination is not as hard as it seems, because some tasks (like raising money and getting incorporated) are an O(1) pain in the ass, whether you’re big or small, and others (like selling and promotion) depend more on energy and imagination than any kind of special training.

From American Association for the Advancement of Science’s “The Effects of Patenting in the AAAS Scientific Community” [250 kb PDF] (2006):

Forty percent of respondents who had acquired patented technologies since January 2001 reported difficulties in obtaining those technologies. Industry bioscience respondents reported the most problems, with 76 percent reporting that their research had been affected by such difficulties. In contrast, only 35 percent of academic bioscience respondents reported difficulties that affected their research.

Of the 72 respondents who reported that their work had been affected by the technology acquisition process, 58 percent of those reported that their work was delayed. Fifty percent reported that they had to change their research, and 28 percent reported abandoning their research project as acquisition of the necessary technologies involved overly complex licensing negotiations.

Conservatives are more ruthless than liberals

history, politics / /

From Alan Wolfe’s “Why Conservatives Can’t Govern” (The Washington Monthly: July/August 2006):

Political parties expend the time and grueling energy to control government for different reasons. Liberals, while enjoying the perquisites of office, also want to be in a position to use government to solve problems. But conservatives have different motives for wanting power. One is to prevent liberals from doing so; if government cannot be made to disappear, at least it can be prevented from doing any good. The other is to build a political machine in which business and the Republican Party can exchange mutual favors; business will lavish cash on politicians (called campaign contributions) while politicians will throw the money back at business (called public policy). …

Historically and philosophically, liberals and conservatives have disagreed with each other, not only over the ends political systems should serve, but over the means chosen to serve those ends. Whether through the ideas of James Madison, Immanuel Kant, or John Stuart Mill, liberals have viewed violent conflict as regrettable and the use of political institutions as the best way to contain it. Conservatives, from the days of Machiavelli to such twentieth-century figures as Germany’s Carl Schmitt, have, by contrast, viewed politics as an extension of war, complete with no-holds-barred treatment of the enemy, iron-clad discipline in the ranks, cries of treason against those who do not support the effort with full-throated vigor, and total control over any spoils won. From a conservative point of view, separation of powers is divisive, tolerance a luxury, fairness another word for weakness, and cooperation unnecessary. If conservatives will not use government to tame Hobbes’ state of nature, they will use it to strengthen Hobbes’ state of nature. Victory is the only thing that matters, and any tactic more likely to produce victory is justified.

The K Street Project, then, did not arise spontaneously out of the ether. When Republicans in Congress began to inform lobbyists that in return for influence they would have to fire all the Democrats in their firms, they may have broken with long-standing traditions, but they were simply carrying forward politics-as-warfare the way conservative political philosophers have historically understood it. Liberals do not generally have objections to working with conservatives; indeed, having conservatives sign off on any expansion of government adds to the legitimacy of that expansion. But conservatives tend to see working with liberals as corrupting; in the immortal words of conservative activist Grover Norquist, “bipartisanship is another name for date rape.” K Street is to lobbying what Fox News is to journalistic objectivity. In the world that contemporary conservatives have brought into being, rules are not applicable to all parties to a conflict. Rules are part of the conflict, and whoever wins the conflict gets to change the rules.

Conservatives cannot govern well; reason #1: Medicare reform

politics / /

From Alan Wolfe’s “Why Conservatives Can’t Govern” (The Washington Monthly: July/August 2006):

If government is necessary, bad government, at least for conservatives, is inevitable, and conservatives have been exceptionally good at showing just how bad it can be. Hence the truth revealed by the Bush years: Bad government–indeed, bloated, inefficient, corrupt, and unfair government–is the only kind of conservative government there is. Conservatives cannot govern well for the same reason that vegetarians cannot prepare a world-class boeuf bourguignon: If you believe that what you are called upon to do is wrong, you are not likely to do it very well.

Three examples–FEMA, Medicare, and Iraq– should be sufficient to make this point. …

The question of whether Medicare reform will prove politically fruitful for Republicans is still open. But the question of whether it has proven to be an administrative nightmare is not. There were two paths open to Republicans if they had been interested in creating an administratively coherent system of paying for the prescription drugs of the elderly. One was to give the elderly nothing and insist that every person assume the full cost of his or her medication. The other was to have government assume responsibility for the costs of those drugs.

It is significant that in America’s recent debates over prescription drugs, no one, not even the Cato Institute, argued that government should simply not be in the business at all. As a society, we accept–indeed, we celebrate–the fact that older people can live longer and better lives thanks to radically improved medical technology as well as awe-inspiring advances in pharmacology. A political party which consigned to death anyone who could not afford to participate in this medical revolution would die an early death itself.

But Republicans were just as unwilling to design a sensible program as they were unable to eliminate the existing one. To prove their faith in the market, they gave people choices, when what they wanted was predictability. To pay off the pharmaceutical industry, they refused to allow government to negotiate drug prices downward, thereby vastly inflating the program’s costs. To make sure government agencies didn’t administer the benefit, they lured in insurance companies with massive subsidies and imposed almost no rules on what benefits they could and could not offer. The lack of rules led to a frustrating chaos of choices. And the extra costs had to be made up by carving out a so-called “doughnut hole” in which the elderly, after having their drug purchases subsidized up to a certain point, would suddenly find themselves without federal assistance at all, only to have their drugs subsidized once again at a later point. Caught between the market and the state, Republicans picked the worst features of each. No single human being could have designed a program as unwieldy as this one. It took the combined efforts of every faction in today’s conservative movement to produce a public policy so removed from common sense.

The contradictions of conservatism

history, politics / /

From Alan Wolfe’s “Why Conservatives Can’t Govern” (The Washington Monthly: July/August 2006):

A conservative in America, in short, is someone who advocates ends that cannot be realized through means that can never be justified, at least not on the terrain of conservatism itself. In the past, the ends sought were the preservation of hierarchy, even if the means included appeals to democratic sentiment. In more recent times, conservatives promised order and stability through means dependent upon the uncertainties and insecurities of the market.

How conservatives are like communists

history, politics / /

From Alan Wolfe’s “Why Conservatives Can’t Govern” (The Washington Monthly: July/August 2006):

Eager to salvage conservatism from the wreckage of conservative rule, right-wing pundits are furiously blaming right-wing politicians for failing to adhere to right-wing convictions. …

Conservative dissidents seem to have done an admirable job of persuading each other of the truth of their claims. Of course, many of these dissidents extolled the president’s conservative leadership when he was riding high in the polls. But the real flaw in their argument is akin to that of Trotskyites who, when confronted with the failures of communism in Cuba, China and the Soviet Union, would claim that real communism had never been tried. If leaders consistently depart in disastrous ways from their underlying political ideology, there comes a point where one has to stop just blaming the leaders and start questioning the ideology.

The power of PR

business, language & literature, politics / /

From Paul Graham’s “The Submarine” (April 2005):

Why do the media keep running stories saying suits are back? Because PR firms tell them to. One of the most surprising things I discovered during my brief business career was the existence of the PR industry, lurking like a huge, quiet submarine beneath the news. Of the stories you read in traditional media that aren’t about politics, crimes, or disasters, more than half probably come from PR firms.

I know because I spent years hunting such “press hits.” Our startup spent its entire marketing budget on PR: at a time when we were assembling our own computers to save money, we were paying a PR firm $16,000 a month. And they were worth it. PR is the news equivalent of search engine optimization; instead of buying ads, which readers ignore, you get yourself inserted directly into the stories. …

If anyone is dishonest, it’s the reporters. The main reason PR firms exist is that reporters are lazy. Or, to put it more nicely, overworked. Really they ought to be out there digging up stories for themselves. But it’s so tempting to sit in their offices and let PR firms bring the stories to them. After all, they know good PR firms won’t lie to them.

A good flatterer doesn’t lie, but tells his victim selective truths (what a nice color your eyes are). Good PR firms use the same strategy: they give reporters stories that are true, but whose truth favors their clients. …

Where the work of PR firms really does get deliberately misleading is in the generation of “buzz.” They usually feed the same story to several different publications at once. And when readers see similar stories in multiple places, they think there is some important trend afoot. Which is exactly what they’re supposed to think. …

Remember the exercises in critical reading you did in school, where you had to look at a piece of writing and step back and ask whether the author was telling the whole truth? If you really want to be a critical reader, it turns out you have to step back one step further, and ask not just whether the author is telling the truth, but why he’s writing about this subject at all.

Online, the answer tends to be a lot simpler. Most people who publish online write what they write for the simple reason that they want to. You can’t see the fingerprints of PR firms all over the articles, as you can in so many print publications — which is one of the reasons, though they may not consciously realize it, that readers trust bloggers more than Business Week. …

I didn’t realize, till there was an alternative, just how artificial most of the writing in the mainstream media was. I’m not saying I used to believe what I read in Time and Newsweek. Since high school, at least, I’ve thought of magazines like that more as guides to what ordinary people were being told to think than as sources of information.

How to get 1 million MySpace friends

business, security, social software, tech in changing society, technology / /

From Nate Mook’s “Cross-Site Scripting Worm Hits MySpace” (Beta News: 13 October 2005):

One clever MySpace user looking to expand his buddy list recently figured out how to force others to become his friend, and ended up creating the first self-propagating cross-site scripting (XSS) worm. In less than 24 hours, “Samy” had amassed over 1 million friends on the popular online community.

How did Samy transcend his humble beginnings of only 73 friends to become a veritable global celebrity? The answer is a combination of XSS tricks and lax security in certain Web browsers.

First, by examining the restrictions put into place by MySpace, Samy discovered how to insert raw HTML into his user profile page. But MySpace stripped out the word “javascript” from any text, which would be needed to execute code.

With the help of Internet Explorer, Samy was able to break the word JavaScript into two lines and place script code within a Cascading Style Sheet tag.

The next step was to simply instruct the Web browser to load a MySpace URL that would automatically invite Samy as a friend, and later add him as a “hero” to the visitor’s own profile page. To do this without a user’s knowledge, the code utilized XMLHTTPRequest – a JavaScript object used in AJAX, or Web 2.0, applications such as Google Maps.

Taking the hack even further, Samy realized that he could simply insert the entire script into the visiting user’s profile, creating a replicating worm. “So if 5 people viewed my profile, that’s 5 new friends. If 5 people viewed each of their profiles, that’s 25 more new friends,” Samy explained.

It didn’t take long for friend requests to start rolling in – first in the hundreds, then thousands. By 9:30pm that night, requests topped one million and continued arriving at a rate of 1,000 every few seconds. Less than an hour later, MySpace was taken offline while the worm was removed from all user profiles.

California’s wide-open educational software reveals personal info

education, security, tech in changing society, technology / /

From Nanette Asimov’s “Software glitch reveals private data for thousands of state’s students” (San Francisco Chronicle: 21 October 2005):

The personal information of tens of thousands of California children — including their names, state achievement test scores, identification numbers and status in gifted or special-needs programs — is open to public view through a security loophole in dozens of school districts statewide that use a popular education software system.

Teacher names and employee identification numbers are also visible to anyone logging onto the system, which is used locally by school districts including San Francisco, San Jose and Hayward.

The problem occurs when the districts issue a generic password to teachers using the system. Until the teacher changes to a unique password, anyone can type in a teacher’s user name and generic password and gain access to information about students that is supposed to be guarded as closely as the gold in Fort Knox. …

San Francisco administrators immediately shut down access to the service, called OARS — Online Assessment Reporting System — after a reporter phoned and said she had been able to access student information for all the children in two middle-school classes where the teachers had not yet changed their passwords. …

Most of the 96 districts statewide that use the system are in Southern California and the Central Valley. …

“We have confidence in the professionalism of our teachers” not to share their passwords, Bradshaw said.

But told how simple it was to gain access to the student records of any teacher who had not yet changed to a unique password, the administrators said they planned to make sure teachers did so.

“We will definitely monitor that,” Quinn said. “We don’t want anyone getting into student information.”
