Crazy Ants are Insane

I meant to highlight this fascinating piece in The New York Times earlier, but better late than never.

First, the name:

The ants are called crazy ants. That’s their actual name. Many people call them Rasberry crazy ants, and some people call them Tawny crazy ants and refuse to call them Rasberry crazy ants. 

Rasberry coming from not a scientist or a professor, but an exterminator who noticed these wild ants in Texas.

Rasberry crazy ants do not have a painful bite, but they effectively terrorize people by racing up their feet and around their bodies, coursing everywhere in their impossibly disordered orbits. (They’re called crazy ants because their behavior seems psychotic.) Some people in Texas have become so frustrated with crazy ants that they have considered selling their houses or been driven to the verge of divorce. “Usually, the husband doesn’t think it’s such a big deal, and the wife is going batty,” one exterminator explained. An attorney living on an infested farm south of Houston told me: “It reminds me of the scenes in Africa, where you see flies crawling all over people. Occasionally they’ll knock one off, but for the most part they’re so accustomed to it that they finally give up.”

Crazy ants decimate native insects. They overtake beehives and destroy the colonies. They may smother bird chicks struggling to hatch. In South America, where scientists now believe the ants originated, they have been known to obstruct the nasal cavities of chickens and asphyxiate the birds. They swarm into cows’ eyes.

So far, there is no way to contain them. In the fall, when the temperature drops, the worker ants are subject to magnificent die-offs, but the queens survive, and a new, often larger crop of crazy ants pours back in the following spring. Rasberry crazy ants were first discovered in Texas by an exterminator in 2002. Within five years, they appeared to be spreading through the state much faster than even the red imported fire ant has. The fire ant is generally considered one of the worst invasive species in the world. The cost of fire ants to Texas has been estimated at more than $1 billion a year.

Here is a three-year old video that shows how fast these crazy ants scurry about:

 

Definitely worth reading the entire thing. Fascinating reporting. And scary how species can be so invasive!

“The Things You’ll Miss” by Derek Thompson

Writing in The Atlantic, Derek Thompson recounts the last few months of his mom’s life (who was battling pancreatic cancer) and his ability to cope with the grief after she passed away. It’s a beautiful, poignant piece titled “The Things You’ll Miss.”

A boundless black terror is how I imagined life without my mom. The history of grief, or what we know of it, is written by its greatest sufferers and ransacked with horror stories, lugubrious poetry, and downward-spiraling memoirs plunged in sadness. For some people, the death of a loved one is truly life-stopping, and I worried it would stop mine.

Then, in the weeks after she died, something strange happened. I did not plunge. Life did not stop. Instead, I felt something so unspeakably strange, so blasphemous, that I wondered for if I could talk or write about it, at all. I felt okay.

Even stranger, I discovered, is that I wasn’t strange, at all. Despite the warnings that grief would drag me through the prescribed five stages and discard me in a darker place, bereavement researchers have recently learned that we’ve been wrong about loss for centuries. For some, grief is a dull and unrelenting ache that fades—or doesn’t. But for many of us, grief is something else. Grief is resilience.

I loved this passage of retelling of happy stories:

For the 16 months after her diagnosis, I returned the favor. We never spoke of the food she couldn’t eat, the thick hair she couldn’t grow back, or the weight she couldn’t keep. Instead, riding home from New York once a month and bounding onto her bed, I’d serve a feast of happy stories harvested from a life spent trying not to worry. I cried often, but privately, in the stairway at work, on the train behind a pair of sunglasses, and in my apartment, indulging a memory behind a locked door. But I only lost it twice in front of her, both times trying to say the same thing: What makes me saddest isn’t imagining all the things I’ll miss, but imagining all the things you’ll miss. The wedding dances, the wine-fueled parties, her birthday cards, each emblazoned with ludicrously incorrect ages. For mom, who drew kinetic energy from every drip of living, as if by photosynthesis, and braved the winter of life with spring in her heart, smiling like a sweet little maniac all the way to the end, cancer was such cosmic robbery.

This is a beautiful passage, how grief is like undulating waves:

Mourning, even for the resilient, is a study in extremes, and, for the family and friends filling out our house, the crescendos were violent. We would scream at each other, and then laugh over wine, and then scream some more, and back to the wine. Grief is not a steady process, Bonanno said, but rather an “oscillation,” like everything inside of us. Muscles tighten and relax, our bodies warm and cool, and so do our tempers. In that house, in those last days, we might have thought of ourselves as individual antibodies, pinging around the home, attaching ourselves to tasks to invent a small sense of utility. But we were also one house, one body, mourning to and fro.

A must-read in its entirety.

What it Takes to Air a Football Game on FOX

Writing in The Verge, David Pierce traces what it takes for FOX to air a football game on a given Sunday. FOX is the network broadcasting the Super Bowl in 2014, so every game is essentially a preparation for the team that brings us close to the action on our televisions:

It starts at 6AM on Saturday, in the cold, dark Foxboro morning, as the Fox team shows up to unload three 53-foot trucks. Stadiums don’t have much in the way of built-in A / V equipment, so Fox (and every other network) carries everything the crew will need for the weekend inside those trucks — the show has to be built and broken down every weekend. This Saturday, it has to be even faster: there’s a college football game at 4PM.

Kevin Callahan, Fox’s director of technical operations, estimates Fox credentialed between 150 and 200 people for the weekend, from Troy Aikman and director Rich Russo to runners and microphone holders. The network brings in about $25 million worth of equipment, with thousands of individual parts. (Callahan is reluctant to even guess at the number: “It depends on how small you want to get,” he says. “I mean, the production switcher alone has 1,000 buttons on it.”) Callahan and his crew have to wire the entire stadium, rig up cameras and audio, and make sure hundreds of different parts are able to connect to each other. “This is actually a very well-oiled machine,” he says. “The mobile units that we’re using here were designed in 2005 and 2006 — at the time they were eight years ahead of their time.”

In one truck, graphics and production. In another, 20 feet away in the concrete garage underneath the stands, replay and audio. Russo estimates he has 15 cameras and 13 tape machines this week, capturing and replaying angles from all over the stadium — there’s even a helicopter flying around shooting from above. The graphics team, eight or so young guys in polo shirts, is preparing more than 1,000 graphics, with every record or outcome accounted for. Rich Russo and producer Richie Zyontz talk to everyone through speakers and headsets, voicing their constant chatter to the 150-member Fox crew throughout the weekend. Colby Bourgeios, the team’s technical director, sits at his giant switcher ready to put any camera, any person, any replay on TV with the press of one of a thousand buttons. Audio consultant Fred Aldous watches and listens on his own console, making sure everything sounds as good as it looks — in stereo and 5.1-channel surround sound.

Eventually, nearly everyone says, you just learn to do it by feel.

This bit on 4K television was interesting:

Fox has been using 4K cameras for three years, but not to broadcast the game, which the crew says would be pointless given current bandwidth and TV technology. It’s all about replay. “We can do things like zoom in, look at a guy’s foot… we can see precisely a nice, solid foot, and a line right there, and know that the guy is in,” says Colby Bourgeios, Fox’s technical director. This year is about fine-tuning — finding the right camera, the right lens, the right capture and extraction devices. But even when 4K works convincingly, Callahan says, “we need it to be the first or second replay. If we were to sit there and have a 4K replay that we could show two plays later… and that would have reversed the official’s call, well, that’s awful.” He won’t add anything to the Fox broadcast that will slow it down, or impede it in any way.

Good read if you’re into football and/or sports.

Heartbreak at the Edge of Mongolia

Ariel Levy’s piece “Thanksgiving in Mongolia” is agonizing, riveting, and devastating. It’s incredibly well-written and recounts her choosing to travel to Mongolia while pregnant:

People were alarmed when I told them where I was going, but I was pleased with myself. I liked the idea of being the kind of woman who’d go to the Gobi Desert pregnant, just as, at twenty-two, I’d liked the idea of being the kind of girl who’d go to India by herself. And I liked the idea of telling my kid, “When you were inside me, we went to see the edge of the earth.” I wasn’t truly scared of anything but the Mongolian winter. The tourist season winds down in October, and by late November, when I got on the plane, the nights drop to twenty degrees below zero. But I was prepared: I’d bought snow pants big enough to fit around my convex gut and long underwear two sizes larger than I usually wear.

To be pregnant is to be in some kind of discomfort pretty much all the time. For the first few months, it was like waking up with a bad hangover every single morning but never getting to drink—I was nauseated but hungry, afflicted with a perpetual headache, and really qualified only to watch television and moan. That passed, but a week before I left for Mongolia I started feeling an ache in my abdomen that was new. “Round-ligament pain” is what I heard from everyone I knew who’d been pregnant, and what I read on every prenatal Web site: the uterus expanding to accommodate the baby, as he finally grew big enough to make me look actually pregnant, instead of just chunky. That thought comforted me on the fourteen-hour flight to Beijing, while I shifted endlessly, trying to find a position that didn’t hurt my round ligaments.

No spoilers here. Just read the whole thing.

The Six Day Water Fast

Ben Marcus, in his mid-forties, felt pain throughout his body. He decided to try something unconvential: a six-day fast consisting of nothing but drinking water. He chronicles his (mis)-adventures in this piece for GQ.

TrueNorth lacks the whorehouse comforts of a spa. There isn’t even a pool, which seems to violate some central tenet of California apartment complexes. It feels more like a scientific-research center. There are daily lectures and cooking demos, and the guest rooms are stocked with DVDs of slightly NSFW health documentaries. Today at the clinic they showed a grim video called The Pleasure Trap, an unflinching lecture on why we eat, and eat, and fucking eat, what isn’t good for us. Salt, sugar, and fat, combined with chemicals in processed foods, trick the brain in the same way as cocaine, and the brain flushes our bodies with dopamine, perhaps the most blissful, and addictive, homemade chemical we have. Once we find a way to trigger it, we kill ourselves to get more. Literally.

That evening, with no dinner to cook, eat, and clean up, I prepare my water smoothie, made of nothing but distilled water, and turn on the Food Network. If I can’t eat food, I’ll watch some. On TV, pre-scandal Paula Deen and her son are making corn dogs, fried okra, croissant-dough muffins with caramelized pecans. These things look gorgeous and obscene, like the invented genitalia of a new species. But after watchingThe Pleasure Trap, it seems wrong to refer to this stuff as food. More like recreational drugs for the mouth, with nasty side effects like diabetes. Still, I’m drooling. I love these recreational drugs. I go to foreign countries just to try exotic versions. I’m a user. I do food.

Just not today, and, if I survive, not for the next five days.

It appears the fast has worked wonders, though I appreciate the cautious outlook that this might have been a short-term victory:

Throughout my stay, a six-day fast has been regarded with amused smiles. Pathetic amateur, they don’t say. One doctor says everyone should do a long fast at least once in their lives. What’s long, I ask. Twenty-one days. Maybe thirty. Now I see the appeal. Once you get over the misery of the first few days, things start to look up and you get this feeling that something profoundly necessary is happening inside you. I’ve lost sixteen pounds, and a deep bend at the knees is surprisingly pain-free. My hands no longer ache. My skin is clear. The whites of my eyes look Photoshopped.

Don’t try this at home, folks. Seriously: from personal experience, even fasting for twelve hours is bound to make you dizzy, and you don’t want to be falling down stairs when you attempt something this bold…

David Sedaris on His Sister’s Suicide

Writing in The New Yorker, this is a deeply moving personal reflection by one of my favorite writers, David Sedaris, on his youngest sister’s suicide:

“Why do you think she did it?” I asked as we stepped back into the sunlight. For that’s all any of us were thinking, had been thinking since we got the news. Mustn’t Tiffany have hoped that whatever pills she’d taken wouldn’t be strong enough, and that her failed attempt would lead her back into our fold? How could anyone purposefully leave us, us, of all people? This is how I thought of it, for though I’ve often lost faith in myself, I’ve never lost it in my family, in my certainty that we are fundamentally better than everyone else. It’s an archaic belief, one that I haven’t seriously reconsidered since my late teens, but still I hold it. Ours is the only club I’d ever wanted to be a member of, so I couldn’t imagine quitting. Backing off for a year or two was understandable, but to want out so badly that you’d take your own life?

The family’s back-and-forth on what to name their beach house was amusing in an otherwise very melancholy piece.

Richard Feynman on Cargo Cult Science and the Importance of Integrity

Richard Feynman’s Caltech commencement address given in 1974 is titled “Cargo Cult Science.” In it, he describes his experience in experimenting with various pseudoscience trends (extrasensory perception, PSI phenomena, and so on) and explains the difference between this “cargo cult science” and real science. It’s a fascinating read in its entirety. The story actually appears in Surely You’re Joking, Mr. Feynman! (Adventures of a Curious Character), which I highly recommend reading.

One notable passage I wanted to highlight was Feynman recounting of an experiment that was excellent scientific work:

There have been many experiments running rats through all kinds of mazes, and so on–with little clear result. But in 1937 a man named Young did a very interesting one. He had a long corridor with doors all along one side where the rats came in, and doors along the other side where the food was. He wanted to see if he could train the rats to go in at the third door down from wherever he started them off. No. The rats went immediately to the door where the food had been the time before.

The question was, how did the rats know, because the corridor was so beautifully built and so uniform, that this was the same door as before? Obviously there was something about the door that was different from the other doors. So he painted the doors very carefully, arranging the textures on the faces of the doors exactly the same. Still the rats could tell. Then he thought maybe the rats were smelling the food, so he used chemicals to change the smell after each run. Still the rats could tell. Then he realized the rats might be able to tell by seeing the lights and the arrangement in the laboratory like any commonsense person. So he covered the corridor, and still the rats could tell.

He finally found that they could tell by the way the floor sounded when they ran over it. And he could only fix that by putting his corridor in sand. So he covered one after another of all possible clues and finally was able to fool the rats so that they had to learn to go in the third door. If he relaxed any of his conditions, the rats could tell.

Now, from a scientific standpoint, that is an A-number-one experiment. That is the experiment that makes rat-running experiments sensible, because it uncovers that clues that the rat is really using– not what you think it’s using. And that is the experiment that tells exactly what conditions you have to use in order to be careful and control everything in an experiment with rat-running.

I looked up the subsequent history of this research. The next experiment, and the one after that, never referred to Mr. Young. They never used any of his criteria of putting the corridor on sand, or being very careful. They just went right on running the rats in the same old way, and paid no attention to the great discoveries of Mr. Young, and his papers are not referred to, because he didn’t discover anything about the rats. In fact, he discovered all the things you have to do to discover something about rats. But not paying attention to experiments like that is a characteristic example of cargo cult science.

Feynman’s closing remark on what is truly important—no matter where you work—is your integrity. Because that’s something that cannot be taken away from you:

So I have just one wish for you—the good luck to be somewhere where you are free to maintain the kind of integrity I have described, and where you do not feel forced by a need to maintain your position in the organization, or financial support, or so on, to lose your integrity. May you have that freedom.

Fascinating read.

Between Moscow and St. Petersburg, a Disappearing Russia

At the edges of Russia’s two great cities of Moscow and St. Petersburg, another Russia is present. This is the land of the broken road and poor residents. The New York Times, in a piece titled “The Russia Left Behind,” delves deeper, offering a look into this depressing state:

This will not be apparent at next year’s Winter Olympics in Sochi, nor is it visible from the German-engineered high-speed train. It is along the highway between Moscow and St. Petersburg — a narrow 430-mile stretch of road that is a 12-hour trip by car — that one sees the great stretches of Russia so neglected by the state that they seem drawn backward in time.

As the state’s hand recedes from the hinterlands, people are struggling with choices that belong to past centuries: to heat their homes with a wood stove, which must be fed by hand every three hours, or burn diesel fuel, which costs half a month’s salary? When the road has so deteriorated that ambulances cannot reach their home, is it safe to stay? When their home can’t be sold, can they leave?

A sad reality:

There are spots on this highway where it seems time has stopped. A former prison guard is spending his savings building wooden roadside chapels, explaining that “many souls” weigh on his conscience. A rescue worker from the nuclear meltdown at Chernobyl is waiting, 27 years later, for the apartment the Soviets promised him as a reward. Women sit on the shoulder, selling tea to travelers from a row of samovars. Above them, pillars of steam vanish into the sky, just as they did in 1746, the year construction on the road began.

On the state of the M10 Highway, connecting Moscow and St. Petersburg:

The M10 highway looks normal enough at the southern limits of St. Petersburg, but then, with a jolt, it begins to atrophy. For the next 430 miles the surface of the highway, while paved, varies from corduroy to jaw-rattling patchwork. Sometimes it has four lanes, sometimes two, with few medians and frequently no lane markings at all.

Traffic creeps forward behind a procession of 18-wheelers hauling goods from the port of St. Petersburg, passing villages with names like Cockroachville, Teacupville and Chessville. It is the most heavily traveled cargo route in Russia, and yet for truck drivers complying with safety regulations, it takes 24 hours to travel between the two cities, said Viktor Dosenko, vice president of the International Transport Academy. On a good road, he said, the trip should take 10 hours.

From time to time, the dismal condition of the highway has made national news. After a snowstorm in November, about 10,000 vehicles got stuck in a traffic jam that extended more than 70 miles, trapping some drivers for three days in subzero temperatures. Valery Voitko, who heads a trade union of long-haul truck drivers, described his drivers that week as “not even angry any more, but in a state of dumb despair, that year in and year out the same thing happens.”

On Russia’s disappearing villages:

Between the great cities are hundreds of disappearing settlements: towns becoming villages, villages becoming forest. The Soviets cut off support for them during efficiency drives in the 1960s and ’70s, which categorized villages as “promising” or “unpromising.”

But the death of a village is a slow process. A geographer, Tatiana Nefyodova, calls them “black holes,” and estimates that they make up 70 to 80 percent of Russia’s northwest, where Moscow and St. Petersburg act as giant vacuum cleaners, sucking people and capital from the rest of the country.

A really well-done piece that illustrates the plight of the Russian poor.

The Story of How Twitter was Founded

Nick Bilton pens a fascinating piece in The New York Times on the origins of Twitter and the roles Jack Dorsey, Evan WIlliams, and Noah Glass played from the company’s creation to becoming one of the top social media sites in the world.

On Jack Dorsey’s luck in discovering Ev Williams in a coffee shop:

In 2005, Jack Dorsey was a 29-year-old New York University dropout who sometimes wore a T-shirt with his phone number on the front and a nose ring. After a three-month stint writing code for an Alcatraz boat-tour outfit, he was living in a tiny San Francisco apartment. He had recently been turned down for a job at Camper, the shoe store.

His luck changed one morning as he was sitting at Caffe Centro off South Park. As Dorsey looked up from his laptop, punk rock blaring through his earphones, he noticed a man about his age. Evan Williams, then 33, was a minor celebrity on the San Francisco tech scene. A few years earlier, he sold the Web-diary service he co-founded, Blogger, a word he popularized, to Google for several million dollars. Now Williams was using some of his Blogger money to finance a new company, Odeo, that made podcasts. Odeo was co-founded by his neighbor and friend, Noah Glass. Its dingy loft headquarters happened to be located around the corner, a block from South Park. Williams had stopped in and ordered a coffee.

He sent a resume, got hired immediately, and the rest, as they say, is history. The idea for Twitter came a bit later, after the company Dorsey was working for, Odeo, became obsolete when Apple unveiled podcasts on iTunes:

One night in late February 2006, around 2 a.m., Dorsey sat in Glass’s parked car as rain poured down on the windshield. The two were sobering up after a night of drinking vodka and Red Bull, but the conversation, as usual, was about Odeo. Dorsey blurted out that he was planning his exit strategy. “I’m going to quit tech and become a fashion designer,” Glass recalls him saying. He also wanted to sail around the world. Glass pushed back: He couldn’t really want to leave the business entirely, could he? “Tell me what else you’re interested in,” he said. Dorsey mentioned a Web site that people could use to share their current status — the music they were listening to or where they were. Dorsey envisioned that people would use it to broadcast the simplest details about themselves — like “going to park,” “in bed” and so forth.

On how the name Twitter was born:

Soon, the question of a name came up. Williams jokingly suggested calling the project “Friendstalker,” which was ruled out as too creepy. Glass became obsessive, flipping through a physical dictionary, almost word by word, looking for the right name. One late afternoon, alone in his apartment, he reached over to his cellphone and turned it to silent, which caused it to vibrate. He quickly considered the name “Vibrate,” which he nixed, but it led him to the word “twitch.” He dismissed that too, but he continued through the “Tw” section of the dictionary: twist, twit, twitch, twitcher, twitchy . . . and then, there it was. He read the definition aloud. “The light chirping sound made by certain birds.” This is it, he thought. “Agitation or excitement; flutter.” Twitter.

One of Twitter’s early problems was the question of who was leading the company? Williams or Dorsey?

Dorsey raced home to try to figure out a plan for his resignation, but the Twitter board instead offered him a three-month window to fix the site and its issues. Not much changed, however, even as text bills mounted, and the site continued to crash. Before the three months were up, Dorsey recalled, Sabet and Wilson took him to a breakfast at the Clift hotel and told him that they were replacing him as C.E.O. with Williams. Dorsey sat before a bowl of uneaten yogurt and granola as he was offered stock, a $200,000 severance and a face-saving role as the company’s “silent” chairman. No one in the industry had to know that he was fired. (Investors would not want to be seen as pitting one founder against another anyway.) But Dorsey had no voting rights at the company. He was, essentially, out.

On Ev Williams ignoring the advice that it’s bad to hire your friends in a start-up:

He [Williams] saw his success as the result of a lot of hard work and also a fair bit of luck, and he wanted to give the people he knew the opportunity to be a part of it. He hired his sister, to stock the kitchens at Twitter; his wife, Sara, was hired to design the new offices; and he employed numerous friends from Google. Among them was Dick Costolo, who had recently sold his start-up for $100 million. After they bumped into each other at a party in 2009, Williams asked him to be Twitter’s chief operating officer. On his first day, Costolo, a former improv comedian, thumbed his first tweet: “First full day as Twitter COO tomorrow,” he wrote. “Task #1: undermine CEO, consolidate power.”

In the end, this is a familiar story in Silicon Valley:

In Silicon Valley, most companies have their own Twitter story: a co-founder, always a friend, and often the person with the big idea behind the company, who is pushed out by another, hungrier co-founder. 

Twitter is my favorite social network, so I highly recommended reading this piece in entirety.

The Incredible Story of How the iPhone Came to Be

The best thing I’ve read today is this fascinating New York Times Magazine piece on how the iPhone was developed. From concept to prototype to Steve Jobs’s unveiling of the revolutionary device, this piece has it all. It is so much better than the section devoted to the iPhone in Walter Isaacson’s biography of Steve Jobs. Absolutely a must-read.

On how incredibly secretive Steve Jobs tried to keep the announcement of the iPhone:

Jobs was so obsessed with leaks that he tried to have all the contractors Apple hired — from people manning booths and doing demos to those responsible for lighting and sound — sleep in the building the night before his presentation. Aides talked him out of it.

Now this is a great way to phrase it:

Ponder the individual impacts of the book, the newspaper, the telephone, the radio, the tape recorder, the camera, the video camera, the compass, the television, the VCR and the DVD, the personal computer, the cellphone, the video game and the iPod. The smartphone is all those things, and it fits in your pocket

On the initial gamble of the iPhone and the buggy versions that existed at launch:

It’s hard to overstate the gamble Jobs took when he decided to unveil the iPhone back in January 2007. Not only was he introducing a new kind of phone — something Apple had never made before — he was doing so with a prototype that barely worked. Even though the iPhone wouldn’t go on sale for another six months, he wanted the world to want one right then. In truth, the list of things that still needed to be done was enormous. A production line had yet to be set up. Only about a hundred iPhones even existed, all of them of varying quality. Some had noticeable gaps between the screen and the plastic edge; others had scuff marks on the screen. And the software that ran the phone was full of bugs.

This bit about the compromises that Apple took to make the demo iPhone work is phenomenal:

The software in the iPhone’s Wi-Fi radio was so unstable that Grignon and his team had to extend the phones’ antennas by connecting them to wires running offstage so the wireless signal wouldn’t have to travel as far. And audience members had to be prevented from getting on the frequency being used. “Even if the base station’s ID was hidden” — that is, not showing up when laptops scanned for Wi-Fi signals — “you had 5,000 nerds in the audience,” Grignon says. “They would have figured out how to hack into the signal.” The solution, he says, was to tweak the AirPort software so that it seemed to be operating in Japan instead of the United States. Japanese Wi-Fi uses some frequencies that are not permitted in the U.S.

There were multiple versions of the iPhone built near launch:

Many executives and engineers, riding high from their success with the iPod, assumed a phone would be like building a small Macintosh. Instead, Apple designed and built not one but three different early versions of the iPhone in 2005 and 2006. One person who worked on the project thinks Apple then made six fully working prototypes of the device it ultimately sold — each with its own set of hardware, software and design tweaks. 

The first iPhone prototype in 2005 had a wheel (like the iPod):

From the start of the project, Jobs hoped that he would be able to develop a touch-screen iPhone running OS X similar to what he ended up unveiling. But in 2005 he had no idea how long that would take. So Apple’s first iPhone looked very much like the joke slide Jobs put up when introducing the real iPhone — an iPod with an old-fashioned rotary dial on it. The prototype really was an iPod with a phone radio that used the iPod click wheel as a dialer. “It was an easy way to get to market, but it was not cool like the devices we have today,” Grignon says.

On how stressful the environment was:

The pressure to meet Jobs’s deadlines was so intense that normal discussions quickly devolved into shouting matches. Exhausted engineers quit their jobs — then came back to work a few days later once they had slept a little. Forstall’s chief of staff, Kim Vorrath, once slammed her office door so hard it got stuck and locked her in, and co-workers took more than an hour to get her out. “We were all standing there watching it,” Grignon says. “Part of it was funny. But it was also one of those moments where you step back and realize how [expletive] it all is.”

And that ending to the piece? What a tear jerker. It put a huge smile on my face.

Seriously, you should read the whole thing.
