The Answer Factory: Fast, Disposable, and Profitable as Hell | Magazine
The Answer Factory: Fast, Disposable, and Profitable as Hell | Magazine: "By next summer, according to founder and CEO Richard Rosenblatt, Demand will be publishing 1 million items a month, the equivalent of four English-language Wikipedias a year. Demand is already one of the largest suppliers of content to YouTube, where its 170,000 videos make up more than twice the content of CBS, the Associated Press, Al Jazeera English, Universal Music Group, CollegeHumor, and Soulja Boy combined. Demand also posts its material to its network of 45 B-list sites — ranging from eHow and Livestrong.com to the little-known doggy-photo site TheDailyPuppy.com — that manage to pull in more traffic than ESPN, NBC Universal, and Time Warner’s online properties (excluding AOL) put together."

David's Favourite Captain Haddock Curses
David's Favourite Captain Haddock Curses: "From the simple ('dogs!', 'rats!') to the scientific ('pithecanthropuses!') to the sublime ('vegetarian!'), you've just gotta love Captain Haddock of Tintin fame for his unique turn of phrase. I've tried to capture as many of his idiocyncratic curses as possible."

For example, grab hold of the common thread running through these moldy oldies, which are all about Ferdinand Magellan’s trip ‘round the globe. Well, mostly about that."

The Corner on National Review Online
The Corner on National Review Online: "My favorite insight about humor and the divine comes from the poet Galway Kinnell, who wrote that “laughter is our stuttering in a language we can’t speak yet.” What he’s talking about is the language of transcendence, of what C. S. Lewis called the state of being “surprised by joy.”"

Be lucky - it's an easy skill to learn - Telegraph
Be lucky - it's an easy skill to learn - Telegraph:
"* Unlucky people often fail to follow their intuition when making a choice, whereas lucky people tend to respect hunches. Lucky people are interested in how they both think and feel about the various options, rather than simply looking at the rational side of the situation. I think this helps them because gut feelings act as an alarm bell - a reason to consider a decision carefully.
* Unlucky people tend to be creatures of routine. They tend to take the same route to and from work and talk to the same types of people at parties. In contrast, many lucky people try to introduce variety into their lives. For example, one person described how he thought of a colour before arriving at a party and then introduced himself to people wearing that colour. This kind of behaviour boosts the likelihood of chance opportunities by introducing variety.
* Lucky people tend to see the positive side of their ill fortune. They imagine how things could have been worse. In one interview, a lucky volunteer arrived with his leg in a plaster cast and described how he had fallen down a flight of stairs. I asked him whether he still felt lucky and he cheerfully explained that he felt luckier than before. As he pointed out, he could have broken his neck."

Be lucky - it's an easy skill to learn - Telegraph
Be lucky - it's an easy skill to learn - Telegraph: "My research revealed that lucky people generate good fortune via four basic principles. They are skilled at creating and noticing chance opportunities, make lucky decisions by listening to their intuition, create self-fulfilling prophesies via positive expectations, and adopt a resilient attitude that transforms bad luck into good.
I wondered whether these four principles could be used to increase the amount of good luck that people encounter in their lives. To find out, I created a 'luck school' - a simple experiment that examined whether people's luck can be enhanced by getting them to think and behave like a lucky person."

Lost Garden: Flash Love Letter (2009) Part 1
Lost Garden: Flash Love Letter (2009) Part 1: "Flash games are currently the ghetto of the game development industry. Compared to the number of players it serves, the Flash game ecosystem makes little money, launches few careers, and sustains few developer owned businesses. Despite the vast potential of the ecosystem, Flash games contribute surprisingly little to the advancement of game design as an art or a craft.
In order to understand why this promising game platform is such a surprising dissapointment, we'll look at Flash games from three perspectives:
* Chapter 2 - Making money: How do Flash developers currently make money.
* Chapter 3 - Generating value: How Flash developers currently create 'valuable' game for their players?
* Chapter 4 - Reaching customers: How developers currently reach their players.
* Chapter 5 - Premium Flash games as a service: A mental model for understanding the new world of web gaming.
For each step, I'll cover alternative techniques that give you, the game developer, make even better games."

In one session at the blackboard, John introduced Lisp—all you could do with car, cdr, cons, cond, lambda, and recursion."

4 People Who Faced Disaster—And How They Made it Out Alive - Rules to Survive Fire, Tornado, Blizzard and Hurricanes - Popular Mechanics
4 People Who Faced Disaster—And How They Made it Out Alive - Rules to Survive Fire, Tornado, Blizzard and Hurricanes - Popular Mechanics: "Some disasters are simply not survivable. But most are, and research on human behavior suggests that the difference between life and death often comes down to the simple—yet surprisingly difficult—task of recognizing threats before they overwhelm you, then working through them as discrete challenges. The people who survive disasters tend to be better prepared and more capable of making smart decisions under pressure. Not everyone is born with these traits, but almost anyone can learn them. Here’s how to wire your brain for survival."

My theme today is that when we talk about consumers’ “trust” in financial services, we’re actually wrapping up about four or five different kinds of trust within that one single word - and on closer examination there are significant differences in the current status of each kind."

3. Like any upscale American or Beijing supermarket, they have a sushi case. The prices are half what they’d be in America, but the pieces of fish are much thinner.
4. They cut up meat in front of you. A whole pig was being butchered on a table. A roast duck was being sliced for packaging."

'That leads to fine throughput, but it's not great for latency. You can easily get into situations where you might be stuck for seconds at a time in a queue just waiting to get to the head of the queue."

HR 3200 from a systems design perspective (Part I) : Bruce F. Webster
HR 3200 from a systems design perspective (Part I) : Bruce F. Webster: "On the occasions where I have reviewed the actual text of major legislation, I have been struck by the parallels between legislation and software, particularly in terms of the pitfalls and issues with architecture, design, implementation, testing, and deployment. Some of the tradeoffs are even the same, such as trading off the risk of “analysis paralysis” (never moving beyond the research and analysis phase) and the risks of unintended consequences from rushing ill-formed software into production. Yet another similarity is that both software and legislation tend to leverage off of, interact with, call upon, extend, and/or replace existing software and legislation. Finally, the more complex a given system or piece of legislation is, the less likely that it will achieve the original intent."

How American Health Care Killed My Father - The Atlantic (September 2009)
How American Health Care Killed My Father - The Atlantic (September 2009): "After the needless death of his father, the author, a business executive, began a personal exploration of a health-care industry that for years has delivered poor service and irregular quality at astonishingly high cost. It is a system, he argues, that is not worth preserving in anything like its current form. And the health-care reform now being contemplated will not fix it. Here’s a radical solution to an agonizing problem."

Appy framework
Appy framework: "pod (python open document) is a library that allows to easily generate documents whose content is dynamic. The principle is simple: you create an ODF (Open Document Format) text document (with OpenOffice Writer 2.0 or higher for example), you insert some Python code at some places inside it, and from any program written in Python, you can call pod with, as input, the OpenDocument file and a bunch of Python objects. pod generates another ODF text document (ODT) that contains the desired result. If you prefer to get the result in another format, pod can call OpenOffice in server mode to generate the result in PDF, DOC, RTF or TXT format."

COMPUTERS: THEIR BUILT-IN LIMITATIONS
COMPUTERS: THEIR BUILT-IN LIMITATIONS: "Computer programing is self-inflicted torture. The problem is to make a mindless machine behave rationally. Before you can tell the machine how to solve a problem, you must first figure out how your own brain solves it—every step, every detail. You watch your brain as it effortlessly snakes its way along some line of reasoning that loops back through itself, and then you try to draw a diagram showing how your brain did it, and you discover that your brain couldn’t possibly have done it—yet you know it did. And there sits the computer. If you can’t explain to yourself, how are you ever going to explain to it"

Pixar’s Brad Bird on Fostering Innovation
Pixar’s Brad Bird on Fostering Innovation: "Steve Jobs hired him, says Bird, because after three successes (Toy Story, A Bug’s Life, and Toy Story 2) he was worried Pixar might struggle to stay innovative. Jobs told him: “The only thing we’re afraid of is complacency—feeling like we have it all figured out,” Bird quotes his boss as saying “…We want you to come shake things up.” Bird explains to McKinsey how he did it — and why, for “imagination-based companies to succeed in the long run, making money can’t be the focus.”
The piece is behind McKinsey’s pay wall, but we extract its 9 key lessons below."

glasses for computer use
If you want glasses simply for helping other programmers, get a pair
of single-vision glasses for the over-the-shoulder distance. Here are
two ways to figure out what prescription you need. You'll need to know
about how far it is from your eyes to the screens you can't read, and
you'll need your "driving" prescription.
Method 1. Use the following guideline: If the screens you have to read
are 3 feet away, add +1.00 diopter to your driving glasses
prescription's spherical correction. If the screens are 2 feet away,
add +1.50 diopters. If they are 1.5 feet away, add +2.00 diopters.
Most likely they are no closer than that, given that your computer
glasses aren't working for this.
Method 2. Put on your driving glasses and visit the reading glasses
section of your local drug store. With luck, they will have glasses in
every strength from +1.25 to +2.50 (in increments of 0.25). Try on
various strength reading glasses *over* your driving glasses until you
can read at the over-the-shoulder distance. Whatever works is what you
need to add to the spherical correction of your driving glasses.
IMPORTANT: Be sure you're adding a positive number to your driving
prescription, not a negative number. You're a programmer, so I'm sure
you know that when you add +1.00 to the number -2.25, you get -1.25,
*not* -3.25!
If you want a single pair of glasses that will allow you to help
others, but also to see your own screen, for days when you're back and
forth a lot, I suggest getting a pair of "monovision" glasses, with
one lens optimized for over-the-shoulder and one lens optimized for
your own screen. In other words, add +1.5 (or whatever you got above)
to the spherical correction of your driving prescription for one eye
only. Choose the eye based on which eye has the best view of the
screen when you're doing the over-the-shoulder thing.
For the record, I teach Computer Science and have to do a lot of over-
the-shoulder myself, but I also have to see students from the front of
the classroom. So my monovision glasses have one lens of "driving"
prescription and one lens of "over-the-shoulder" prescription. My
guess is that you want one over-the-shoulder lens and one "your own
computer" lens.
If your two prescriptions have slightly different PD values, don't
worry about it. Either will work - my pick would be the larger of the
two (probably the driving prescription).

Blunt warning about greens under the bed | Antonia Senior - Times Online
Blunt warning about greens under the bed | Antonia Senior - Times Online: "Britain is, thankfully, an ideologically barren land. The split between Right and Left is no longer ideological, but tribal. Are you a nice social liberal who believes in markets, or a nasty social liberal who believes in markets? Anthony Blunt’s memoirs, published this week, reveal a different age, one in which fascism and communism were locked in a seemingly definitive battle for souls.
Blunt talks of “the religious quality” of the enthusiasm for the Left among the students of Cambridge. There is only one ideology in today’s developed world that exercises a similar grip. If Blunt were young today, he would not be red; he would be green."
