Are you in a startup career path or are you one and done? Sometimes peoples' first startups are successful. More power to them. I've been pretty lucky, but not that lucky. In a startup career path, failure becomes experience for the next startup, which unfortunately will probably also fail. Repeat until success. And then repeat some more. Of course many people never get a hit, and that is the harsh reality of the startup career. Yet there is more to thinking of startups as a career than rationalizing failure. If you don't know much tech stuff, maybe you should take the time to learn some now. There are dangers in thinking this way though. You can also get too distracted on learning new stuff and never actually get anything done. Perhaps most importantly though, thinking about startups as a career makes it easier to really commit. If you're on the startup career path though, this is it. Update: some good comments on HN.
10 strange hings about the universe you should know Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?273.15°C, where the motion of all particles stops completely. However, you can never actually cool something to this temperature because, in quantum mechanics, every particle has a minimum energy, called “zero-point energy,” which you cannot get below. One of the properties of a negative-energy vacuum is that light actually travels faster in it than it does in a normal vacuum, something that may one day allow people to travel faster than the speed of light in a kind of negative-energy vacuum bubble.

5 data breaches: From embarrassing to deadly - Netflix accidentally reveals rental histories (1) - CNNMoney.com Four years ago, Netflix came up with what seemed like an ingenious plan to improve its movie recommendations algorithm: crowdsource the problem and award the best solution a $1 million prize. But the video rental and streaming company found out that anonymizing data isn't easy. For the first edition of the "Netflix Prize" in 2006, the company released 100 million supposedly anonymized movie ratings. Each included a unique subscriber ID, the movie title, year of release and the date on which the subscriber rated the movie. Just 16 days later, two University of Texas researchers announced that they had identified some of the Netflix users in the data set. Despite the UT findings, Netflix continued the contest and named a $1 million winner. That woman is a lesbian mother who is not open about her sexual orientation. After months of back-and-forth, Netflix called off the second contest and settled the lawsuit.
Google and Verizon Joint Submission on the Open Internet History of 404 What is 404, anyway? Where did it come from? What do the numbers mean? What are the other status codes? How can I use status codes? What does 404 mean? 404 is an HTTP status code. For a normal web page, the status is 200 OK. So where do status codes come from? HTTP status codes were established by the World Wide Web Consortium (W3C) in 1992, as a part of the HTTP 0.9 spec. Berners-Lee based the HTTP status codes on FTP status codes, which were already well established by 1990; the official FTP spec is dated 1985, although FTP has actually been in use much longer. What do the numbers mean? Let’s dissect 404. The first 4 indicates a client error. The middle 0 refers to a general syntax error. The last 4 just indicates the specific error in the group of 40x, which also includes 400: Bad Request, 401: Unauthorized, etc. According to the W3C, 404 Not Found is only supposed to be used in cases where the server cannot find the requested location and is unsure of its status. How can I use status codes?
Are You A Pirate? I read blog posts by Don Dodge and Glenn Kelman today about people jumping from Google to Facebook and it got me thinking about entrepreneurs. Most people have an aversion to risk, my college economics professor told me. Which means they have to be rewarded to take on that risk. The higher the risk, the higher the possible payout has to be for people to jump. We make risk/reward decisions every day, all day. Do I go skiing, and enjoy the rush of flying downhill even though there’s a small chance I’ll blow out a knee? Every time we do something, or don’t do something, there’s a risk/reward algorithm being calculated in our brain. Entrepreneurs, though, are all screwed up. The payouts for starting a business are just terrible when you account for risk. In my youth I was a corporate lawyer, making a very nice salary for representing technology startups in Silicon Valley. But I left the law after just three years to join a startup. But I did it anyway. I don’t care if you’re a billionaire.
10 Tech Concepts You Need to Know for 2010 1. Anthropomimetic Machines No matter how closely a robot resembles a human on the outside, if you crack it open, the jumble of wires is unlikely to bear much resemblance to our insides. A group of European researchers aims to bridge that gap--its robot prototype is anthropomimetic, meaning it mimics the human form. 2. Yesterday's fuel cells, like those seen here on Spacelab, require a hydrogen infrastructure. Coal is dirty, and fuel cells run on hydrogen--that's the conventional wisdom. 3. For the past five years, scientists at the University of Alberta in Edmonton have been working on the Human Metabolome Project, a database of the 8000 naturally occurring metabolites (that is, small molecules involved in chemical reactions in the body), as well as 1450 drugs, 1900 food additives and 2900 toxins that turn up in blood and urine tests. 4. Scientists at Caltech have been folding microscopic strands of DNA into interesting shapes for the past few years. 5. 6. 7. 8. 9. 10.
2010 Report on Distributed Denial of Service (DDoS) Attacks Published December 20, 2010 Authored by Ethan Zuckerman, Hal Roberts, Ryan McGrady, Jillian York, John Palfrey Introduction Distributed Denial of Service (DDoS) is an increasingly common Internet phenomenon capable of silencing Internet speech, usually for a brief interval but occasionally for longer. This paper makes recommendations for how independent sites can best mitigate the impact of DDoS. You can download the full paper by clicking on Download PDF link above or by clicking here. A joint policy proposal for an open Internet Posted by Alan Davidson, Google director of public policy and Tom Tauke, Verizon executive vice president of public affairs, policy, and communications The original architects of the Internet got the big things right. By making the network open, they enabled the greatest exchange of ideas in history. By making the Internet scalable, they enabled explosive innovation in the infrastructure. It is imperative that we find ways to protect the future openness of the Internet and encourage the rapid deployment of broadband. In October, our two companies issued a shared statement of principles on network neutrality. 1. 2. Today our CEOs will announce a proposal that we hope will make a constructive contribution to the dialogue. First, both companies have long been proponents of the FCC’s current wireline broadband openness principles, which ensure that consumers have access to all legal content on the Internet, and can use what applications, services, and devices they choose.
page The history of 404 Before the beginning of time, when the Internet was still very much under the spell of bare Unix shells and Gopher, before SLIP or PPP became widely used, an ambitious group of young scientists at CERN (Switzerland) started working on what was to become the media revolution of the nineties: the World Wide Web, later to be known as WWW, or simply 'the Web'. Their aim: to create a database infrastructure that offered open access to data in various formats: multi-media. The ultimate goal was clearly to create a protocol that would combine text and pictures and present it as one document, and allow linking to other such documents: hypertext. Because these bright young minds were reluctant to reveal their progress (and setbacks) to the world, they started developing their protocol in a closed environment: CERN's internal network.
