Steve Jobs' Resignation Letter Link post

To the Apple Board of Directors and the Apple Community:

I have always said if there ever came a day when I could no longer meet my duties and expectations as Apple”s CEO, I would be the first to let you know. Unfortunately, that day has come.

I hereby resign as CEO of Apple. I would like to serve, if the Board sees fit, as Chairman of the Board, director and Apple employee.

As far as my successor goes, I strongly recommend that we execute our succession plan and name Tim Cook as CEO of Apple.

I believe Apple”s brightest and most innovative days are ahead of it. And I look forward to watching and contributing to its success in a new role.

I have made some of the best friends of my life at Apple, and I thank you all for the many years of being able to work alongside you.

Mapping Global Human Activity

Felix Pharand-Deschenes’ Anthropocene Mapping project marks the paths of human activity including roadways, railways, airway traffic, internet cables, electricity transmission lines, and underwater data cables. He acquired all this factual information from various US government agencies.

The word “Anthropocene” is especially fitting for this piece of research; the meaning behind the ancient Greek word is derived from - anthropos means “human being” and kainos means “new, current.” The word use commonly used to describe the current “geological epoch”, which is dominated by human activity.

The definition for the Anthropocene proposed by Globaïa:

A period marked by a regime change in the activity of industrial societies which began at the turn of the nineteenth century and which has caused global disruptions in the Earth System on a scale unprecedented in human history: climate change, biodiversity loss, pollution of the sea, land and air, resources depredation, land cover denudation, radical transformation of the ecumene, among others. These changes command a major realignment of our consciousness and worldviews, and call for different ways to inhabit the Earth.

Elon Musk, said to be the model for Tony Stark, wants to die on Mars

For those who don’t read the financial press or the gossip blogs, Musk is a 41-year-old entrepreneur who grew up in South Africa. At 15, he migrated to Canada, worked on farms and at a lumber mill and then got into Queen’s University in Ontario.

After two years, he transferred to Penn, earning degrees in economics and physics. While there, as he recently told Jon Stewart, he concluded that the three areas that would most transform humanity were the Internet, sustainable energy and space exploration.

He dropped out of a graduate physics program at Stanford to help start an Internet map and directory company called Zip2, which was sold to Compaq for more than $300 million.

He took his share of that money and helped create PayPal, serving for a time as its chief executive. When that was sold, he poured his share of his money into SpaceX, a space exploration company; Tesla, an electric car company; SolarCity, a solar power company; and Everdream, a data-center software firm.

SpaceX is the first private company to send a rocket into space. Already profitable, it has a long line of orders to take things into space. Tesla is selling its second model for about $55,000 each. Musk decided to revolutionize three industries all at once and is sort of doing it. His net worth is estimated to be about $2 billion.

Musk also told Businessweek about two other project designs he is working on. The first is something called the Hyperloop, a tube capable of taking people from downtown Los Angeles to downtown San Francisco in 30 minutes. The second is a vertical lift-off supersonic passenger jet that would surpass Boeing. He also hopes to open up a space colony on Mars within 10 or 15 years.”

How the Tesla Turbine Works:

Most people know Nikola Tesla, the eccentric and brilliant man who arrived in New York City in 1884, as the father of alternating current, the form of electricity that supplies power to almost all homes and businesses. But Tesla was a prodigious inventor who applied his genius to a wide range of practical problems. All told, he held 272 patents in 25 countries, with 112 patents in the United States alone. You might think that, of all this work, Tesla would have held his inventions in electrical engineering — those that described a complete system of generators, transformers, transmission lines, motor and lighting — dearest to his heart. But in 1913, Tesla received a patent for what he described as his most important invention. That invention was a turbine, known today as the Tesla turbine, the boundary layer turbine or the flat-disk turbine.

Interestingly, using the word “turbine” to describe Tesla’s invention seems a bit misleading. That’s because most people think of a turbine as a shaft with blades — like fan blades — attached to it. In fact, Webster’s dictionary defines a turbine as an engine turned by the force of gas or water on fan blades. But the Tesla turbine doesn’t have any blades. It has a series of closely packed parallel disks attached to a shaft and arranged within a sealed chamber. When a fluid is allowed to enter the chamber and pass between the disks, the disks turn, which in turn rotates the shaft. This rotary motion can be used in a variety of ways, from powering pumps, blowers and compressors to running cars and airplanes. In fact, Tesla claimed that the turbine was the most efficient and the most simply designed rotary engine ever designed.

If this is true, why hasn’t the Tesla turbine enjoyed more widespread use? Why hasn’t it become as ubiquitous as Tesla’s other masterpiece, AC power transmission? These are important questions, but they’re secondary to more fundamental questions, such as how does the Tesla turbine work and what makes the technology so innovative? We’ll answer all of these questions on the next few pages. But first, we need to review some basics about the different types of engines developed over the years.

Keep reading…

it said tesla. i got excited. i do not regret my actions.

What made me so overwhelmingly angry yesterday was the same thing that has been boiling in my gut for the last two years. When the federal government went after him – and MIT sheepishly played along – they weren’t treating him as a person who may or may not have done something stupid. He was an example. And the reason they threw the book at him wasn’t to teach him a lesson, but to make a point to the entire Cambridge hacker community that they were p0wned. It was a threat that had nothing to do with justice and everything to do with a broader battle over systemic power. In recent years, hackers have challenged the status quo and called into question the legitimacy of countless political actions. Their means may have been questionable, but their intentions have been valiant. The whole point of a functioning democracy is to always question the uses and abuses of power in order to prevent tyranny from emerging. Over the last few years, we’ve seen hackers demonized as anti-democratic even though so many of them see themselves as contemporary freedom fighters. And those in power used Aaron, reframing his information liberation project as a story of vicious hackers whose terroristic acts are meant to destroy democracy.

Reasonable people can disagree about tactics and where and when a particular approach pushes too far. Like Lessig, I often disagreed with Aaron about his particular approach to freeing the world’s information, even if I never disagreed with him about the goal. And one of the reasons why so many hackers and geeks spent yesterday raging against the machine is because so many people in power have been unable to see past the particular acts and understand the intentions and activism. So much public effort has been put into controlling and harmonizing geek resistance, squashing the rebellion, and punishing whoever authorities can get their hands on. But most geeks operate in gray zones, making it hard for them to be pinned down and charged. It’s in this context that Aaron’s stunt gave federal agents enough evidence to bring him to trial to use him as an example. They used their power to silence him and publicly condemn him even before the trial even began.

Yesterday, there was an outpouring of information about his case, including an amazing account from the defense’s expert witness. Many people asked why people didn’t speak up before. I can only explain my reasoning. I was too scared to speak publicly for fear of how my words might be used against him. And I was too scared to get embroiled in the witch hunt that I’ve watched happen over the last three years. Because it hasn’t been about justice or national security. It’s been about power. And it’s at the heart and soul of why the Obama administration has been a soul crushing disappointment to me. I’ve gotten into a ridiculous number of fights over the last couple of years with folks in the administration over the treatment of geeks and the misunderstanding of hackers, but I could never figure how to make a difference on that front. This was a source of serious frustration for me, even as SOPA/PIPA showed that geeks could make a difference.

So here we are today, the world lacking a prodigious child whose intellect scared the shit out of everyone who knew him. He became a toy for a government set on showing their strength. And they bullied him and preyed on his weaknesses and sought to break him. And they did. All for the performance of justice. All before he was even tried in a society that prides itself on innocent until proven guilty. Was depression key to what happened on Friday? Certainly. But it wasn’t the whole story. And that’s what makes it hard for me to stomach.”
