It all comes down to the limbic systems and your prefrontal cortex. Your monkey brain vs. your human brain. And the one thing that has been shown to weaken your limbic response and strengthen the response of your prefrontal cortex? Mindful meditation. (via @christopherjobs)
This device produces a blast of air with each stroke of the bow regardless of whether it is pushed or pulled. The bow makes it possible to operate the blower without using a complicated belt and wheel assembly used in traditional forge blowers. There is a brief pause at the end of each stroke where the fan stops to rotate in the other direction, but this is effectively no different to the intermittent blast of a double acting bellows of Europe or box bellows of Asia. The materials used (wood, bark, bark fibre and clay) are readily available on most continents. No leather, valves or precisely fitted piston gaskets are required as with other types of bellows.
The way he shoots & edits these videos is so good...packing, what, dozens or even hundreds of years of technological evolution into a minute or two of wordless video.
This is a beautifully shot video of the process for making tennis balls, from what looks like bread dough in the first steps to stamping the logo on the ball right before it goes into the canister.
I was commissioned to make a film and shoot a set of images by ESPN for Wilson, to show the manufacturing process of their tennis balls for the US Open. We flew to the factory, shot the film and stills in one day then flew home. Its an amazingly complex manufacture, requiring 24 different processes to make the final ball. It was hot, loud and the people who worked there, worked fast. So much beauty in each stage. I love the mechanics of how things are made, it fills me with great pleasure.
I love the little hand-clasper bots that put the yellow felt on the balls. One question though: the entire video is shot at normal speed, but the people putting the felt on the balls, that seemed sped up. But maybe they were just moving that fast?
Speaking of, feel free to have many possibly conflicting feelings about the people making the balls and their inevitable future replacement by a fully automated system. I know I did! (thx, damien)
This is a scene from Miloš Forman's 1971 film, Taking Off, in which a support group of "square" parents meet to try and understand their children who have run away from home. What a great scene. Unfortunately, the entire movie seems quite difficult to find these days. It's not streaming anywhere and this Blu-ray is $45. (via @dunstan)
In the first film, A Grand Day Out, Nick was going to make Gromit speak and had planned a whole mouth design. The first time he animated Gromit, however, he found that the way the character could communicate using body language and expressive eyebrows was much more powerful than by speaking. So he made a snap decision not to give Gromit a voice, which he's stuck to. Our good animators are able to let you know instantly what the model is thinking or doing.
The latest video from Primitive Technology (previously, awesome) is about making a bow and set of arrows from scratch.
The bow is 1.25 m (55 inches) long and shoots 60 cm (2 feet) long arrows. I don't know the draw weight -- safe to say greater than 15 kg (35 pounds) perhaps? The stave was made from a tree that was cut with a stone axe and split in half with a stone chisel. I don't know it's name but it's common here and is the same wood I use for axe handles.
I love how these videos are shot and edited. The editing feels very contemporary -- quick-fire pacing with very little superfluous material -- but the lack of narration, dialogue, or explanatory text feels old school. Reminds me of the super-effective and efficient Buzzfeed Tasty vids.
If you left the house with a lemon, some copper clips, some zinc nails, some wire, and steel wool but somehow forgot your matches, you can still start a fire. I imagine if you had a large enough lemon and enough wire and metal bits, you could also jumpstart a car or a human heart. (via @kathrynyu)
Gordon Ramsay shows us how to chop an onion, cook rice, debone a fish, cook pasta, and sharpen a knife. We've been watching a lot of Gordon Ramsay videos at our house recently. My daughter's class is studying how restaurants work1 -- they're operating a real restaurant in their classroom today -- so she's been really curious about food.
On a recent weekend when it was just the two of us, we watched Ramsay cook his soft-scrambled eggs (and then made them the next morning), which sent us down a rabbit hole of beef wellington, tacos, turkey, and donuts. If you've only ever seen him yelling at mediocre chefs and restaurant owners on TV, you should give his cooking videos a try...he's a super engaging chef that gets you excited about food and cooking.
The kids' school is big on social studies. As the students move through the grades, they first study the school, then their block, their neighborhood, Manhattan, Mannahatta (same location but adding the dimension of time), and eventually the country and wider world. Minna's group is studying the neighborhood this year and to that end have visited several local businesses, including restaurants, to observe their role in the neighborhood dynamic.↩
From the NY Times and Redglass Pictures, a video in which political advisor Mark McKinnon details how to win an election. His short answer: "successful campaigns tell a good story". My "favorite" part is after discussing his irresponsible fear-mongering campaign for Bush in 2004, McKinnon talks about bowing out of the McCain campaign because he believed Obama was a good man and good for the country and he didn't want to smear him. Wish he could have moved procuring a conscience up a few years. NSFW if you, like me, see George W. Bush and involuntarily start loudly swearing like a sailor.
Matt Might, who is a professor in computer science at the University of Utah and a professor at the Harvard Medical School, responded to a question on Quora about minimizing the chances of having a disabled child and ended up answering two seemingly unrelated questions as well: How do you get tenure? and How do you live the good life? Long story short: he got tenure and started living the good life because he had a disabled child. But you should read the long story; it's worth it.
My son forced me to systematically examine what matters in life -- what really matters -- and in the end, I came to appreciate a quote from his namesake, Bertrand Russell, more than I could have ever imagined:
"The good life is one inspired by love and guided by knowledge."
My first year as a tenure-track professor cannot be described as anything other than an abject failure. I was so desperate to publish and raise funds that I began thin-slicing my research and submitting lots of poor quality papers and grant proposals.
I must have had a dozen rejections in a row that year. It sucked.
I remember huddling on the porch at the end of that year with my wife, telling her, "Well, I'll at least have a job for six more years."
I looked at my young son, cuddled in her arms. I saw his very existence hung in the balance between knowledge and ignorance.
Then it hit me: Life is too precious and too fleeting to waste my time on bullshit like tenure. I didn't become a professor to get tenure. I became a professor to make the world better through science. From this day forward, I will spend my time on problems and solutions that will matter. I will make a difference.
I stopped working on problems for the sole purpose of notching up a publication. I shifted gears to cybersecurity. I found a project on cancer in the med school. I joined a project in chemical engineering using super-computing to fight global warming.
Larch Wood Enterprises is a Nova Scotian company specializing in the manufacture of cutting boards from end grain wood...that is, the top surface of the board shows the rings of the tree. Not only that, but each row on the board is cut from the same stick of wood so you can see how the grain changes through the tree. It's tough to explain...just watch how they make 'em.
End Grain is when the individual boards of wood are arranged so that the grain of the wood (the growth rings) runs vertically (up and down). This puts one end of each board up so that the cutting surface is actually the end of many individual pieces of wood. With the grain aligned in this manner (up and down), when the knife strikes the surface during cutting, the grain of the wood actually separates and then closes when the knife is removed. This accounts for the self-healing aspect of the end-grain surface. The wood itself is not cut, but instead you are cutting between the fibers.
As something of an expert on the topic, I thought this New York Magazine piece about spending time alone in the Big Apple is pretty good. The opening of the piece gets at why busy, crowded NYC is actually a good place for an introvert to be:
Being alone here is a state of mind, a perpetual choice, and an occasional imposition, a burden, and a gift -- and sometimes the very best way to meet a fellow stranger. "Every form of human expressiveness is on display," Vivian Gornick writes of walking the streets by herself, "and I am free to look it right in the face, or avert my eyes if I wish."
And this tip on the Empire State Building is one for the ol' bucket list:
A lot of people don't know this, but the Empire State Building is open until 2 a.m. The last elevator leaves at 1:15. If you go up then, it's empty, it's beautiful, and the city sounds like the ocean.
Each year, using traditional Incan techniques, communities along a canyon in Peru rebuild a rope bridge that has been in continuous use for hundreds of years.
That you can take thousands of thin grass stalks and, through the careful application of engineering and hard work, make them strong enough to hold the weight of several people over a canyon still seems magical. (via cynical-c)
Man at Arms is a YouTube show in which real-life weapons from movies and TV shows are recreated. Recently they made the Bride's Hattori Hanzo sword from Kill Bill. They started from scratch by building a furnace from before the Edo period (before 1603) to smelt the iron ore.
I know zero about swords, but it looks like these guys really did their homework in making as close to a traditional katana blade as they could. (via devour)
As you know, I love videos of how stuff is made. (See below.) Well, I just discovered this treasure trove of more than 300 14-minute videos from a Japanese show called The Making: playlist #1, playlist #2. Each video shows how a different thing is made, from wires to sugar to trophies to cheese and all of them are dialogue-free. Here's the one on how golf balls are made:
When I was a kid, maybe 12 or 13 years old, I watched this program on PBS that showed how a snack food manufacturer came up with a new snack food, from design to manufacturing. The thing that stuck with me the most was that they showed a number of the missteps in-between...like they tried a certain shape with a certain filling and it didn't work out in taste tests, that sort of thing. I LOVED seeing that trial and error in action. I only saw the show once, but it's one of my most vivid childhood TV memories. Maybe it's why I ended up becoming a designer?
Wait, wait! Holy shit, holy shit! I found the show! It was a NOVA program called How to Create a Junk Food that aired in 1988, when I was 14. I couldn't find the video or even a clip, but here's a review in the LA Times.
The ultimate weapon is the flavorist, a 20th-Century alchemist who analyzes natural things like Danish blue cheese or barbecued beef, reconstructs them chemically in the lab and produces their essences to punch up the taste of bland fillings.
Marketing and technology co-produce a croissant-dough cone with a moist meat or cheese filling that appears perfect. But when they test it on the mouths of real consumers (English housewives), it's a bloomin' flop.
Undaunted, the technologists go back to their gizmos and test tubes. After doing such goofy things as gluing electrodes to a chewer's cheeks to get "chew profiles" of different fillings, they come up with a second prototype, Crack a Snack. The wheat-cracker wrapped "savory tube" is called a "triumph of food engineering," which, we're warned, if it is given the proper image, "there's little doubt we'll buy it."
I've never looked closely at my dishwasher's instruction manual before, but apparently all the manuals tell you how best to load the dishwasher. Joe Clark went through a bunch these manuals and compiled screenshots of the "Loading Your Dishwasher" pages and put them on Flickr.
I've read a lot about introverts and extroverts over the years (posted this back in Feb 2003 for example), but this list (found here) of how to care for introverts still hit me like a pile of bricks.
1. Respect their need for privacy.
2. Never embarrass them in public.
3. Let them observe first in new situations.
4. Give them time to think; don't demand instant answers.
5. Don't interrupt them.
6. Give them advance notice of expected changes in their lives.
7. Give them 15 minute warnings to finish whatever they are doing.
8. Reprimand them privately.
9. Teach them new skills privately.
10. Enable them to find one best friend who has similar interests & abilities.
11. Don't push them to make lots of friends.
12. Respect their introversion; don't try to remake them into extroverts.
It's just dawned on me that when something goes wrong in my life, it's often one of the things on this list that's the culprit, especially #4 and #6. And #2 pretty much explains my middle and high school experience. Has anyone read Susan Caine's Quiet: The Power of Introverts in a World That Can't Stop Talking? I've heard great things about it, but haven't had a chance to read yet. Thinking I should bump it to the top of my queue. Holy crap, it's only $2.99 for Kindle...BOUGHT. (via @arainert)
Wow, the art of making marbled paper, a short film from 1970.
Charmingly British, just like the film about the Teddy Grays candy factory or the putter togetherer of scissors. Super cool how the inks are placed on a water bath, swirled expertly to make patterns, and then transferred to the paper. Also of note: the segment on the conservation of old books starting at around 9:55...I never knew they took them apart like that to dunk the pages in water! Sadly, the Cockerell Bindery ceased operation in the late 1980s with the death of Sydney Cockerell and its contents were sold at auction. (thx, matt)
The goal should be that the reader can make the recipe his or her own -- that the instructions are clear and good enough that after a few tries, he or she can improvise to please themselves. The chef gives ideas so that the cook can profit. It's not dictation; it's inspiration.
I wasn't expecting too much of this video about how to eat sushi, but it's actually pretty good. It features Naomichi Yasuda of the highly regard Sushi Yasuda in Manhattan making sushi for a newbie and telling him how it should be eaten.
This Old House + Jiro Dreams of Sushi = this video.
There were open spots at the counter. But the chef, Susumu Yajima, instructed me to take a seat nearby and wait. Eventually I was summoned to a place directly in front of him, and the attack began: Piece after piece in rapid succession, as Yajima barked orders at me.
"Eat now!" he said, milliseconds after passing me a glistening slice of buri (amberjack) atop shari (the finger of rice that forms the base of nigiri sushi). "Use your hand!" he upbraided me, as I reached for my chopsticks. He even instructed me to half-chew one piece before washing it down with sake.
It may hurt to write it. And reading it? For some, that's the worst part. The world might spin a little, and everything familiar to you might fade for a few minutes. But remember, remind yourself as you stand there, you are the lucky one.
And that's not because you aren't dead. You were selected. You get to stand, face the group, the family, the world, and add it up. You're being asked to do something at the very moment when nothing can be done. You get the last word in the attempt to define the outlines of a life. I don't care what you say, bub: That is a gift.
This rule surprised me:
You must make them laugh. Laughs are a pivot point in a funeral. They are your responsibility. The best laughs come by forcing people not to idealize the dead. In order to do this, you have to be willing to tell a story, at the closing of which you draw conclusions that no one expects.
What exactly is a good shot in soccer? The nascent field of soccer analytics is hard at work trying to figure that out. It won't surprise anybody to learn that closer is better, and using your feet is much, much better than using your head. So, much like getting into the lane is of paramount importance in basketball, getting the ball at your feet in front of the goal is just about the best thing you can do in soccer. Getting to the byline (baseline) in the corner of the penalty areas (like where Maicon was in the above video) is a hot destination. That's where you can cut the ball back for a teammate to have one of those coveted close shots. Hey, look at that - it's like basketball again: Get to the goal or get to the corners.
If you were not able to contact her before hand, and you are sure that you want to proceed, find out the location of the wedding. Unless you have been invited, you will have to find out where the wedding ceremony is to be held, and the exact time. Ask family members or mutual friends if it doesn't appear too suspicious, or perhaps check the wedding notices in the local newspaper.
I have never seen something so batshit crazy described in such a calm methodical way. And the photos! The caption for this one is "Enjoy life with your stolen bride or groom":
Jim Koch is the co-founder and chairman of The Boston Beer Company, brewer of the Sam Adams beers. Part of his job is to drink professionally and he does so without getting completely sloshed. What's his secret? Eating a packet of dry yeast before tying one on.
You see, what [expert brewer] Owades knew was that active dry yeast has an enzyme in it called alcohol dehydrogenases (ADH). Roughly put, ADH is able to break alcohol molecules down into their constituent parts of carbon, hydrogen, and oxygen. Which is the same thing that happens when your body metabolizes alcohol in its liver. Owades realized if you also have that enzyme in your stomach when the alcohol first hits it, the ADH will begin breaking it down before it gets into your bloodstream and, thus, your brain.
"And it will mitigate - not eliminate - but mitigate the effects of alcohol!" Koch told me.
Could have used this tip last night. Does this mean no hangovers as well?
Update: I got two kinds of feedback about this post:
1) What's the fun in drinking alcohol if you're not getting drunk? (Good point.)
2) Yeast doesn't really work. What does seem to work is Pepcid AC and Zantac. From Shenglong on Hacker News:
Again, I'm not a chemist or a doctor, but from my preliminary internet research and anecdotal testing (though I have quite a few different data points), Famotadine (OTC) [Pepcid], and higher levels of APO-Ranitidine (can be prescription) [Zantac] seems to slow the rate of ethanol -> acetaldehyde, balancing out the drunkness effect more, and giving you more time to process the acetaldehyde -> acetic acid. I typically go from maxing out at 2 drinks / 3 hour period, to about 11 drinks / 3 hour period on Ranitidine, given favorable conditions. I've had lower levels of success with Famotadine.
And it goes without saying, I don't recommend trying any of this at home. At the local bar on the other hand Nope, not there either. (thx, @natebirdman)
First, the (duck, goose, chicken, or even ostrich) egg is drained, through a tiny hole. Then, using a method akin to batik, it is dipped in dye and painted one color at a time, with the painter applying beeswax to those areas she wants to protect from the next round of dying. The painting implement, called a kishitze, is a stick with an iron tip. (Previously, egg-painters would have used thorns or pig bristles.)
And then the wax is melted and wiped off the egg, revealing the colors underneath. So cool. (via @colossal)
You don't have to be a geek about everything in your life -- or anything, for that matter. But if geekdom is your goal, don't let anyone tell you it's unattainable. You don't have to be there "from the beginning" (whatever that means). You don't have to start when you're a kid. You don't need to be a member of a particular social class, race, sex, or gender.
Geekdom is not a club; it's a destination, open to anyone who wants to put in the time and effort to travel there. And if someone lacks the opportunity to get there, we geeks should help in any way we can. Take a new friend to a meetup or convention. Donate your old games, movies, comics, and toys. Be welcoming. Sharing your enthusiasm is part of being a geek.
You see, I've never been able to get a chocolate chip cookie exactly the way I like. I'm talking chocolate cookies that are barely crisp around the edges with a buttery, toffee-like crunch that transitions into a chewy, moist center that bends like caramel, rich with butter and big pockets of melted chocolate. Cookies with crackly, craggy tops and the complex aroma of butterscotch. And of course, that elusive perfect balance between sweet and salty.
Some have come close, but none have quite hit the mark. And the bigger problem? I was never sure what to change in order to get what I want. Cookies are fickle and the advice out there is conflicting. Does more sugar make for crisper cookies? What about brown versus white? Does it matter how I incorporate the chocolate chips or whether the flour is blended in or folded? How about the butter: cold, warm, or melted?
So many questions to ask and answers to explore! I made it my goal to test each and every element from ingredients to cooking process, leaving no chocolate chip unturned in my quest for the best. 32 pounds of flour, over 100 individual tests, and 1,536 cookies later, I had my answers.
Dang, this is like The Power Broker for baked goods, a cookie magnum opus.
It may not be immediately clear from looking at this map, but my hunch that there's a better way to hunt was right. There isn't one corner of the page where Waldo is always hiding; readers would have already noticed if his patterns were so obvious. What we do see, as highlighted in the map below, is that 53 percent of the time Waldo is hiding within one of two 1.5-inch tall bands, one starting three inches from the bottom of the page and another one starting seven inches from the bottom, stretching across the spread.
The directions for parallel parking (that you get from the DMV, or in your driver's ed course) are actually very precise and if you follow them exactly, you will park your car perfectly every time. You do not need to practice, you just need to fucking follow the directions.
After experimenting on protozoa, rats, and his eight children, Ehret recommended that the international traveler, in the several days before his flight, alternate days of feasting with days of very light eating. Come the flight, the traveler would nibble sparsely until eating a big breakfast at about 7:30 a.m. in his new time zone -- no matter that it was still 1:30 a.m. in the old time zone or that the airline wasn't serving breakfast until 10:00 a.m. His reward would be little or no jet lag.
The diet was adopted by US government agencies and other groups as well as Ronald Reagan, but it difficult to stick to. Recently, researchers in Boston have devised a simpler anti-jet lag remedy:
The international traveler, they counsel, can avoid jet lag by simply not eating for twelve to sixteen hours before breakfast time in the new time zone-at which point, as in Ehret's diet, he should break his fast. Since most of us go twelve to sixteen hours between dinner and breakfast anyway, the abstention is a small hardship.
According to the Harvard team, the fast works because our bodies have, in addition to our circadian clock, a second clock that might be thought of as a food clock or, perhaps better, a master clock. When food is scarce, this master clock suspends the circadian clock and commands the body to sleep much less than normally. Only after the body starts eating again does the master clock switch the circadian clock back on.

I was poking around on YouTube for "how to" videos (one of my favorite video genres) the other day when I hit a small jackpot: a bunch of How Do They...? videos from the National Film Board of Canada. A favorite shows how chain link fences are made:
This video seems like it was made specifically for kottke.org. In the first half of it, you learn how cranberries are harvested. In the second half, there's gorgeous HD slo-mo footage of wakeskating through a cranberry bog.
A short video about the ingredients that go into every can of Play-Doh:
Sadly, the composition of the amazing fragrance is not revealed, but Wired asked a perfumer about it a couple of years ago:
Hasbro's patent admits to vanilla, but that's just to throw us off the scent. The real formula for this iconic odor is guarded like the crown jewels. After talking with New York perfumer Christopher Brosius, who offers a Play-Doh fragrance, we suspect that it draws from the aromatic flowers of the heliotrope, aka the cherry pie plant.
Steinway & Sons, the celebrated piano making company, recently produced this video of how their grand pianos are constructed. Their process for building pianos has changed so little that they were able pair 1980s factory tour audio from former chairman John Steinway to contemporary footage of their Astoria, NY factory.
You can see how little has changed as you watch this 1929 film of how a Steinway piano was made:
Some of the shots in the two videos are identical, e.g. the men pulling the piano rim out of the mold or choosing spruce for the sounding boards. It interesting to compare these two videos with Wednesday's video of how Telsa sedans are made. Together, the three form a view of the progression of automation in manufacturing. I wonder if the Tesla robots could construct a piano that sounds as good as a Steinway? (via open culture)
Tesla got the factory for a song from Toyota in 2010, spent about a year or so setting up tooling and started producing the Model S sedan in mid-2012. The automaker brings in raw materials by the truckload, including the massive rolls of aluminum that are bent, pressed, and formed to create the car. Those lightweight components are assembled by swarm of red robots in an intricate ballet that is mesmerizing to behold.
Karen Cheng learned to dance in a year. Here's a video of her progress, from just a few days in to her final number:
Here's my secret: I practiced everywhere. At bus stops. In line at the grocery store. At work -- Using the mouse with my right hand and practicing drills with my left hand. You don't have to train hardcore for years to become a dancer. But you must be willing to practice and you better be hungry.
This isn't a story about dancing, though. It's about having a dream and not knowing how to get there -- but starting anyway. Maybe you're a musician dreaming of writing an original song. You're an entrepreneur dying to start your first venture. You're an athlete but you just haven't left the chair yet.
The interesting thing is, Cheng basically did the same thing in her professional life as well.
I decided to become a designer, but I had no design skills. I thought about going back to school for design, but the time and money commitment was too big a risk for a career choice I wasn't totally sure of.
So I taught myself -- everyday I would do my day job in record time and rush home to learn design. Super talented people go to RISD for 4 years and learn design properly. I hacked together my piecemeal design education in 6 months -- there was no way I was ready to become a designer. But I was so ready to leave Microsoft. So I started the job search and got rejected a few times. Then I got the job at Exec.
The first few weeks were rough. Everyday I sat in front of my computer trying my damnedest and thinking it wasn't good enough. But everyday I got a little bit better.
Last month, we posted a video of Tim Knoll doing ridiculous and panic-inducing circus style tricks on his bike. In the video below, he explains how he does the bike limbo, riding under several semi trucks in a row. Just because he tells you how to do it, does not mean you should try it. In fact, it is the expressed opinion of this blog you should not try it. However, if you do try it and you do feel yourself falling -- which you will, because let's be honest -- don't try to lift your head up. Just fall, because as Knoll says, "scrapes are better than stitches."
Until fairly recently, recycled glass was not made into new glass bottles. But now recycling plants can use optical sorting to separate out colored glass from clear glass so the latter can be used to make new bottles. Here's how the process works.

Remember that the only representation of you, no matter what your station, is you -- your presentation, your demeanor. You simply must attend. Stand when someone enters the room, especially if you are lowly and he is the boss, and even if the reverse is true. Look them in the eye. Ask yourself: Does anybody need an introduction? If so, before you say one word about business, introduce them to others with pleasure in your voice. If you can't muster enthusiasm for the people you happen upon in life, then you cannot be gracious. Remember, true graciousness demands that you have time for others.
Alex Cornell has constructed a handy infographic to help you decide where to sit at a restaurant or dinner party table.
7 Person Rectangle: It's very easy to get screwed in this scenario. While it may appear like you can sit anywhere except the ends, this is not so. You are at risk of sitting next to the lonely end-seat, which requires you to speak soley to that person for the duration of the meal.
If your car is ever stolen, your first calls should be to every cab company in the city. You offer a $50 reward to the driver who finds it AND a $50 reward to the dispatcher on duty when the car is found. The latter is to encourage dispatchers on shift to continually remind drivers of your stolen car. Of course you should call the police too but first things first. There are a lot more cabs than cops so cabbies will find it first -- and they're more frequently going in places cops typically don't go, like apartment and motel complex parking lots, back alleys etc. Lastly, once the car is found, a swarm of cabs will descend and surround it because cabbies, like anyone else, love excitement and want to catch bad guys.
Yesterday I was pairing the socks from the clean laundry, and figured out the way I was doing it is not very efficient. I was doing a naive search -- picking one sock and "iterating" the pile in order to find its pair. This requires iterating over n/2 * n/4 = n^2/8 socks on average.
As a computer scientist I was thinking what I could do? sorting (according to size/color/...) of course came into mind to achieve O(NlogN) solution.
And everyone gets it wrong. The correct answer is actually:
1) Throw all your socks out.
2) Go to Uniqlo and buy 15 identical pairs of black socks.
3) When you want to wear socks, pick any two out of the drawer.
4) When you notice your socks are wearing out, goto step 1.
So as a parent, you're left with the question not just of how to talk to your child about tragedy, but of whether you're talking to your child for your child -- or for yourself. There's the question of what to say, but also when, and if, you should say it. "If you're feeling panicked, and like there's no place safe in the world, then that's a good time to step back and get those thoughts in order," Dr. Rappaport suggested. "But if we try to wait until we've fully come to terms with something like this, then we'll never be able to talk. In fact, we'd never be able to get out of bed in the morning."

1/2 meat + 1/2 meat = 3/2 meat. Forgetting is natural, like Chipotle meat, so let me remind you that when you add fractions you only add the top part, when the bottom part is the same number. Therefore, when you're asked what type of meat, and you say "half chicken and half steak", it should equal one serving of meat. But it never does. Because a scoop of meat is kinda just a scoop of meat, and nobody in Chipotle management has yet introduced new "half" scoops with which to more precisely address this perfectly legal request. So use it. IMPORTANT: Unlike with the beans, you should make your position on the half meats clear from the beginning, otherwise they charge you for "extra meat."
Now that you're properly equipped, your next challenge is time! You're going to want to read, and read, and read-but modern life sometimes makes that difficult. What's to be done?
Take the book with you everywhere, that's what. Bank line-ups, buses, bathrooms, those precious 8 minutes while the pasta boils - you know what to do! A few pages here, a few pages there, and next thing you know, you're 500 pages in, with only another 200 to go.
Then there's all the time you'll save by not watching television. Remember: the most highly-praised shows in recent years are always compared to ... Victorian novels! Some of them are straight-up based on them! Just read the originals. They are always better.
You will need an email address to do things like register for blog accounts, Facebook, Twitter, and more. This email will have to be something entirely separate from your "real" email addresses. There are a lot of free options out there, but be aware that sending an email from many of them also sends information in the headers that could help identify you.
When I started blogging, I set up an email address for the blog with Hotmail. Don't do this. Someone quickly pointed out the headers revealed where I worked (a very large place with lots of people and even more computers, but still more information than I was comfortable with). They suggested I use Hushmail instead, which I still use. Hushmail has a free option (though the inbox allocation is modest), strips out headers, and worked for me.
Cocktail enthusiast Martin Doudoroff explains how to make an Old Fashioned without using any of the "various bad ideas" (e.g. "There is no slice of orange in an Old Fashioned") that have crept in over the years.
Sugar (and the scant water it is dissolved in) mellows the spirit of the drink. Not much is required, just a little, as the quality of today's spirits is so much higher than it typically was when the Old Fashioned was born. A little splash of simple syrup generally suffices. Gum syrup, rich simple syrup, demerara syrup, brown sugar syrup, sugar cane syrup (the variety filtered of molasses solids) all are great choices. Agave syrup or other neutral diet-sensitive sweeteners may suffice.
Honey, maple syrup, molasses or other strongly-flavored sweeteners do not belong in an Old Fashioned, which is not to say you cannot or should not create nice variations on the Old Fashioned with them.
If not for the photos, I would not have believed this story: a woman duct-taped a bunch of food to her body in order to attract raccoons. No, really:
Just before entering coon HQ, duct-tape your bounty of trash food all over yourself. Raccoons' propensity to enjoy garbage-can snacks, coupled with their shitty attitude and distinct facial markings, makes them the crust punks of the animal kingdom (without the heroin problem and terrible taste in music). And just like crusties, they'll approach without warning and snatch a turkey sub right out of your hands, so you can only imagine how appetizing you're going to look with two-week-old baguettes for arms.
One comestible raccoons seem to find yucky, however, is broccoli. Use their aversion to your aesthetic and protective advantage by surrounding danger zones (i.e., your junk) with appropriate amounts of the leafy green stuff.
Hey Edith, Kreayshawn is nothing...join me in waving your cane at this girl in the food suit. The kids today, really.
The fastest method is one of Steffen's own design: boarding alternating rows at the same time, starting with the window seats. The secret, he says, is that it leaves passengers elbow room to stow their luggage at the same time.
Even random boarding is faster than the back-to-front boarding the airlines currently use. (via jcn)
I'd been wondering if a video like this existed, but I'd never been able to find it before. "Most of us probably take our rolls of toilet paper for granted." I like seeing how the cardboard tubes are made.
Are officials troubling you for fingerprints? "There's a nongreasy glue, like a mucilage," he said, that is more or less invisible once applied. "You put it on your thumb. You roll your thumb over your heel. Now, you've got a heel print on your thumb for no one who exists."
A few things became clear as soon as their replies came in. First of all, I'll have to throttle back my use of Twitter and Facebook to get this writing done (and I may never rev up my idle Quora account after all.) Secondly, scheduling intervals of regular exercise and renewal amid the hours of writing will be essential.
I'm talking about those rugged paper bags of hardwood charcoal that are bound at the top with a zipper-like string seam that looks as if it was made to cleanly unravel. Sometimes it doesn't and then you can yank and yank to no avail. And even when it does there seems to be some magic involved, like the gods of charcoal are smiling down on you.
Service journalism at its finest...now I won't have to tug on the string like an uncomprehending chimp and then just rip the bag. Ok fine, fail to rip the bag because I'm not strong enough and go inside and get the scissors and cut it. Like a fancy gentleman.
I cobbled together this set up out of the desire to properly archive my design work. Next thing I knew I started getting paid for it, and it became an integral part of my work. I am simply listing my equipment and a little bit about what I know to get some designers started in figuring out the best way to shoot their own work.
Jason Fried reveals how he got good at making money. I am not a full-fledged member of the Church of 37signals, but one of my favorite lessons from them is that a business needs to practice how to make money in order to get good at it...it's not something that you just turn on when monetizing mode strikes.
So here's a great way to practice making money: Buy and sell the same thing over and over on Craigslist or eBay. Seriously.
Go buy something on Craigslist or eBay. Find something that's a bit of a commodity, so you know there's always plenty of supply and demand. An iPod is a good test. Buy it, and then immediately resell it. Then buy it again. Each time, try selling it for more than you paid for it. See how far you can push it. See how much profit you can make off 10 transactions.
Start tweaking the headline. Then start fiddling with the product description. Vary the photographs. Take some pictures of the thing for sale; use other photos with other items, or people, in them. Shoot really high-quality shots, and also post crappy ones from your cell-phone camera. Try every variation you can think of.
Before we can figure out how to improve our end results, it's important to understand exactly what's going on when an onion browns. First, the onions begin by sweating. As they slowly heat up, moisture from their interior (they are roughly 75% water by weight) begins to evaporate, forcing its way out of the onion's cells, and causing them to rupture in the process. This breakdown of the cells is what causes onions to soften during the initial stages of cooking.
Maybe it's because I have an oddly intense interest in croissants, but I found this 10-minute video about how to make them fascinating. Watch at least until the 1 kg sheet of butter is placed on the dough to be folded over several times.
Spoiler: they turn out great, which was unexpected because so often croissants are more bready and dry than flakey and moist, even in France. (thx, aaron)
Let the design team be the design experts. Your job is to be the business expert. Ask them how their design solutions meet your business goals. If you trust your design team, and they can explain how their recommendations map to those goals, you're fine. If you neither trust them, nor can they defend their choices it's time to get a new design team.
This should be printed out and nailed into the forehead of every designer and their clients a la Luther's Ninety-Five Theses, you know, for easy reference.
I don't want to have to explain to your parents why you didn't graduate, so I went to the Dean and I made a deal. The deal is you can either wait it out and hope that we don't identify you, or you can identify yourself to your lab instructor and you can complete the rest of the course and the grade you get in the course is the grade you earned in the course.
If you've got a Mac, the "droid" sound that Android phones make -- yep, the one from the commercials -- can be produced in the following manner:
1. Open Terminal.app
2. Type say -v "Cellos" "droid" at the prompt
3. Experiment: say -v "Cellos" "droid. sucks."
4. Or say -v "Cellos" "droid want to be iphone when droid grow up"
5. And finally, say "i am trying to unlock the mysteries of the universe, like how the big bang happened and where all the lost socks go after being in the dryer that really makes me mad"
Over at Serious Eats, Kenji Lopez-Alt assures us that while you can't make restaurant-quality Neapolitan pizza at home, you can come damn close. Best thing is, his technique doesn't involve lining your oven with bricks and is actually as easy as making regular pizza at home.
After cooking for around a minute and a half, the bottom crust achieved the perfect degree of char-even better than what I was getting on the stone. Interestingly enough, the pan was actually cooler than the stone I was using, maxing out at around 450 degrees. So how does a 450 degree pan brown better and faster than a 550 degree stone? It's a matter of heat capacity and density.
The heat capacity of a material is directly related to the amount of energy that a given mass of material holds at a given temperature. Even though stone has almost twice the heat capacity than steel (.2 kcal/kg C vs. .1 kcal/kg C), it loses in two ways: it is far less dense than steel, and it has a much lower rate of heat conduction than steel. The pizza cooking in a skillet is not just getting energy from the pan-it's getting energy from the burner below the pan as it gets rapidly conducted through the metal.
It's a clear demonstration of how when cooking foods, what matters it the amount of energy transferred, not just the temperature you cook at. The two are often directly related, but not always.
I have said it before but will repeat: I love Kenji's nerdiness about the science combined with the ability to come up with the solution that's easiest for non-nerds to appreciate and implement. It is a rare and wonderful thing to observe.
If you are at first lonely, be patient. If you've not been alone much, or if when you were, you weren't okay with it, then just wait. You'll find it's fine to be alone once you're embracing it.
We could start with the acceptable places, the bathroom, the coffee shop, the library. Where you can stall and read the paper, where you can get your caffeine fix and sit and stay there. Where you can browse the stacks and smell the books. You're not supposed to talk much anyway so it's safe there.
14. I don't care if the restaurant is pouring Chateau Latour into Minnie Mouse mugs, don't walk into a restaurant carrying your own wine glasses. It's more pretentious than wearing a monocle and spats.
Somehow it became NSFW day here at kottke.org. So we're rolling with it, in the hay. Here's the Tron version of the Kama Sutra. It is so very NSFW even though everyone stays fully clothed in glowing blue garments.
The beer-like way of serving champagne was found to impact its concentration of dissolved CO2 significantly less. Moreover, the higher the champagne temperature is, the higher its loss of dissolved CO2 during the pouring process, which finally constitutes the first analytical proof that low temperatures prolong the drink's chill and helps it to retain its effervescence during the pouring process.
If you are filming a Girls Gone Wild video or are in the late stages of a wedding reception, pouring champagne directly into a person's mouth is also an effective bubble-preservation technique. (via @matthiasrascher)
According to the In-N-Out nutrition guideline, replacing the Spread with ketchup results in a decrease of 80 calories per sandwich. I know that ketchup has about 15 calories per tablespoon, so If we estimate that an average sandwich has about 2 tablespoons of sauce on it (that's the amount that's inside a single packet), then we can calculate that the Spread has got about 55 calories per tablespoon (110 calories in two tablespoons of Spread minus 30 calories in 2 tablespoons of ketchup = 80 calories difference in the sandwich). With me so far?
It just so happens that relish has about the same caloric density as ketchup (15 calories per tablespoon), and that mayonnaise has a caloric density of 80 calories per tablespoon. Using all of this information and a bit of 7th grade algebra, I was able to quickly calculate that the composition of the Spread is roughly 62 percent mayo, and 38 percent ketchup/relish blend.
A two part (one, two) series on using psychological techniques to improve your creativity.
Interviews with 22 Nobel Laureates in physiology, chemistry, medicine and physics as well as Pulitzer Prize winning writers and other artists has found a surprising similarity in their creative processes (Rothenberg, 1996).
Called 'Janusian thinking' after the many-faced Roman god Janus, it involves conceiving of multiple simultaneous opposites. Integrative ideas emerge from juxtapositions, which are usually not obvious in the final product, theory or artwork.
Physicist Niels Bohr may have used Janusian thinking to conceive the principle of complementarity in quantum theory (that light can be analysed as either a wave or a particle, but never simultaneously as both).
1. Keep them too busy to think.
2. Keep them tired.
3. Keep them emotionally involved.
4. Reward intermittently.
Then the author provides a number of techniques you can use to achieve those goals. Like:
Keep real rewards distant. The rewards in "Things will be better when..." are usually nonrewards -- things will go back to being what they should be when the magical thing happens. Real rewards -- happiness, prosperity, career advancement, a new house, children -- are far in the distance. They look like they're on the schedule, but there's nothing in the To Do column. For example, everything will be better when we move to our own house in the country... but there's nothing in savings for the house, no plan to save, no house picked out, not even a region of the country settled upon.
Can't get enough of the Leidenfrost effect? I know! Me either! In addition to helping with nonstick cooking, the L. effect also allows you to stick your hand into an 850° pot of molten lead without injury.
Skip to 1:55 for the good stuff. Bananas! Absolutely bananas! Oh, and this also works for liquid nitrogen as well. (thx, kyle)
This blog post and accompanying videos show you how to preheat your frying pan to the precise temperature at which your food won't stick. It involves waiting until a small splash of water in the pan forms a single mercury-like ball that floats (literally!) around the pan. Too hot and the water will disperse into smaller balls; too cold and it'll just boil off instantly.
The water "hovering" over the stainless steel pan like mercury happens due to the phenomenon known as the Leidenfrost effect. You can read more about it on wikipedia, but the basic idea is this: at a certain temperature known as the Leidenfrost point (roughly around 320F for water, but varying with surface and pressure), when the water droplet hits the hot pan, the bottom part of the water vaporizes immediately on contact. The resulting gas actually suspends the water above it and creates a pocket of water vapor that slows further heat transfer between the pan and the water. Thus it evaporates more slowly than it would at lower temperatures. At the proper temperature, a similar effect happens with the food you place in the pan, preventing the food from sticking.
This is possibly the best kitchen tip I've ever heard. (thx, jim)
5. Give things names and remember Douglas Adams' rule of capital letters. Capital letters make things important. For example, in The Tipping Point, Gladwell conjures up the following important concepts: The Law of the Few, The Stickiness Factor, and The Power of Context. In Outliers, there's The Matthew Effect and The 10,000-Hour Rule.
It involves finagling some uncooked frozen fries from a local McDonald's under the ruse of a scavenger hunt. Kenji Lopez-Alt explains.
I've been literally giddy with the quality of the fries that have been coming out of my kitchen for the last two days. My wife won't hear the end of it. Even my puppy is wondering why his owner keeps exclaiming "Holy s**t that's good!" every half hour from the kitchen. I've cooked over 43 batches of fries in the last three days, and I'm happy to report that I've finally found a way to consistently reach crisp, golden Nirvana.
Here's the full recipe/instructions. BTW, Kenji's series of posts on Serious Eats is one of the best things going on the web right now (you might remember his sous-vide in a beer cooler hack). Passionate down-to-earth writing about cooking and food backed by some serious skills and scientific knowledge...it's really fun to read.
Keep a food diary not of what you eat but what you experience. She says, "There's a pretty big difference between eating and tasting."
What she means is considering and taking note of the entire experience of tasting: The way the food feels in your mouth, what your beer smells like cold and if it's different when it's lukewarm, what you notice with the first piping-hot bite of sauce compared with the last chilled streaks you scrape up before the server takes the plate. Do you feel one sensation more than others as you chew, a citrusy tingle at first, followed by rush of sweet?
You will get caught, either by a US spy satellite (as in the case of North Korea), a disgruntled defector (as in the case of Iraq), or even an indigenous human rights group (as in the case of Iran). So what should you do if you get caught? First and foremost, do not overreact. Deny. Should the evidence become too powerful, then, change tack. Create a distraction. Argue that the uranium particles found in your country were purposely scattered by a hostile nation. Challenge the credibility of the information provided to the IAEA. Bring up Israel again.
With traditional cookery, when you are exposing your meat to temperatures much hotter than their final desired temperature (say, cooking a steak to 130°F in a 550°F skillet), timing is crucial. The center of your steak is getting hotter and hotter, and it's your job as cook to take it off the flame at precisely the moment that it reaches the desired final temperature. Miss that precise moment, and dinner is ruined.
The beauty of sous-vide cooking is that since you are cooking your steak in a 130°F water bath to begin with, there is absolutely no chance your meat will ever get above that temperature. Guests are an hour late? No problem -- leave the steaks in the water bath, and they'll be exactly the same an hour later.
The Guardian asked a bunch of writers to share their tips for writing fiction. The responses appear in twoparts. Elmore Leonard:
Never use an adverb to modify the verb "said"... he admonished gravely. To use an adverb this way (or almost any way) is a mortal sin. The writer is now exposing himself in earnest, using a word that distracts and can interrupt the rhythm of the exchange. I have a character in one of my books tell how she used to write historical romances "full of rape and adverbs".
Here's Philip Pullman's response in full:
My main rule is to say no to things like this, which tempt me away from my proper work.
I am an expert. I have sliced off thumb tips and fingernails. I have shaved paper-thin wafers of my knuckle and buried a breaking/cimeter knife an inch and a half into my forearm. If it weren't for the stainless steel chainmail "butcher bra" that Josh from Fleisher's bought me for Christmas last year, I might not be alive to write this essay, having perhaps bled out from one of the many horrible chest wounds averted by its Mithril magic.
