» A Speculative Post on the Idea of Algorithmic Authority Clay Shirky Jack Balkin invited me to be on a panel yesterday at Yale’s Information Society Project conference, Journalism & The New Media Ecology, and I used my remarks to observe that one of the things up for grabs in the current news environment is the nature of authority. In particular, I noted that people trust new classes of aggregators and filters, whether Google or Twitter or Wikipedia (in its ‘breaking news’ mode.) I called this tendency algorithmic authority.
Everything you need to know about pointers in C Style used in this document This is regular text. This is a , some code, and some sample output. This is a line of code. CompSci 101 - Big-O notation I recently had a couple of Google interviews in Tokyo, and while preparing for them I ended up with a huge list of things I wanted to brush up on before the interview. It turns out I didn’t get the job (next time!), but I thought I might be able to learn something anyway by working through the list and blogging about the main areas that companies like Google expect you to know. I’ve grabbed the domain computerscience101.org (which currently redirects back here), and when I’ve collected enough posts I plan to throw everything up there as a kind of chapter-by-chapter interview-primer in the hope that it might help someone else out.
Know Where to Run to: The 5 Best Countries With No Extradition The ever-expanding National Security Agency PRISM scandal has raised a host of philosophical questions about government, freedom and privacy. But one question has been on many people's minds that has less to do with big ideas and more to do with practical ones: How did self-confessed leaker/whistleblower Edward Snowden think he was going to escape prosecution by Uncle Sam after he revealed details of the secret government surveillance program? The answer, apparently, was by fleeing to a country with no extradition treaty with the United States: The former CIA employee and NSA contractor is currently hiding out in Hong Kong.
20+ Small Yet Powerful Windows Application Are you bored of using huge software which takes lots of disk space? Do you want to perform all your desired action but with less hard disk consumption ? If these are the questions going on in your mind then this would be the best post for you. A clustering algorithm based on swarm intelligence This paper focuses on swarm intelligence based clustering algorithm. A clustering algorithm based on swarm intelligence is systematically proposed. It derived from a basic model interpreting ant colony organization of cemeteries. Some important concepts, such as swarm similarity, swarm similarity coefficient and probability conversion function are also proposed.
Building Your First App Welcome to Android application development! This class teaches you how to build your first Android app. You’ll learn how to create an Android project and run a debuggable version of the app. You'll also learn some fundamentals of Android app design, including how to build a simple user interface and handle user input. Maze Generation: Growing Tree algorithm # An implementation of the "Growing Tree" algorithm. This one is # notable for it's ability to become nearly identical to Prim's # algorithm, or the Recursive Backtracking algorithm, depending on # how the cells are removed from the list that aggregates as the # algorithm runs.
Audi Backs a Biofuels Startup Field of fuel: A rendering of a new Joule Unlimited biofuel demonstration plant. Joule Unlimited, a startup whose engineered microörganisms produce ethanol from sunlight, water, and carbon dioxide, announced the commissioning of a new demonstration plant last week that will start producing ethanol within the next few weeks. Today, the company announced a partnership with Audi that will help Joule develop and test its fuels. The financial details of the partnership weren’t released, but not including the Audi partnership, Joule has raised $110 million. In small-scale outdoor tests, Joule has shown that its approach, which involves engineered microörganisms housed in special transparent reactors, could produce 8,000 gallons of ethanol per acre per year, a few times more than other advanced biofuels companies (see “TR10: Solar Fuel” and “A Biofuel Process to Replace All Fossil Fuels”).
How to make an external laptop graphics adaptor Laptop graphics have always been something of a joke performance wise. Nvidia and AMD do try, but cramming all those millions of transistors into a low-power, compact package just leads to massive expense and an inability to upgrade. Wouldn't it be perfect if you could simply use a standard external graphics card to power your laptop's 3D graphics? The good news is that you can. The suitably technical-sounding PE4H is just that; a passive PCI-e x16 to x1 adaptor, which enables you to plug an external graphics card into a laptop's ExpressCard slot. Complex systems made simple Albert-László Barabási and Yang-Yu Liu, together with their collaborator Jean-Jacques Slotine at M.I.T., have developed a method for observing large, complex systems. In the image above, red dots represent sensor nodes, which are required to reconstruct the entire internal state of one such system. Image by Mauro Martino.
New programming slang - Programming A question recently posted on stackoverflow.com asked for people to submit programming terms that they or their team have coined and have come into regular use in their own circles. Below are the most popular answers Yoda Conditions The act of using if (constant == variable) instead of natural if (variable == constant),; for example, if (4 == foo). A Real Turing Machine Running The Busy Beaver Remember my article on The Busy Beaver Problem? Well, someone built a real Turing Machine and decided to run the busy beaver with 4 states on it. Here is the video. The Turing Machine in this video runs for 107 steps and halts with the total of 13 ones, as expected. In my article on The Busy Beaver Problem, I also wrote a program that visualizes the tape changes.
