A couple of weeks ago you had the chance to ask Khan Academy lead developer Ben Kamens about the future of online education and the academy itself. Below you'll find his answers to the questions we sent and a few extra that he found interesting.
William Volk may not be the world's oldest game designer, but he's up there. He started out as a play tester for Avalon Hill in 1979, and since then has worked for Activision and other major players in the game space. His current job is with PlayScreen, where he's working on their Word Carnivale iOS game, which is not violent at all. But over the years Volk has worked on slightly violent video games and has watched public outcries over video game violence since 1976. He's also tracked how much less violence we've seen since lead was removed from gasoline. (Editorial interjection: Aren't most remaining pockets of massive gun violence in cities where many poor kids grow up in apartments that have lead paint?) Due to technical problems during the interview, some of the conversation is missing, primarily about the recent spate of multiple murders. It seems, for instance, that Newtown shooter Adam Lanza was heavily into violent video games, which is sure to spark plenty of new discussion about how they affect players. But then again, as Volk reminded me in an email, "If people were influenced by video games, a majority of Facebook users would be farmers by now," a meme that has been floating around Facebook since last year, if not earlier.
Republican staffer Derek Khanna was thrust into the spotlight in December for being fired after submitting a controversial brief titled: Three Myths about Copyright Law and Where to Start to Fix it. In the brief Khanna said: "Current copyright law does not merely distort some markets – rather it destroys entire markets," a view not very popular with Republicans in the House of Representatives. Since the firing, Khanna has continued to speak out on the need for copyright reform and most recently on the law against unlocking cellphones. Derek has graciously agreed to take some time to answer your questions about copyright reform and IP law. As usual, ask as many questions as you'd like, but please, one question per post.
A few weeks ago you had the chance to ask Jack Horner about dinosaurs, science funding, and extinction level events. He's sent back his responses and commented: "Very impressive audience you have!" Read below for more flattery and his answers to your questions.
Ben Kamens spent over 5 years at Fog Creek, eventually working his way up to VP of engineering. However, after watching one of Salman Khan's talks he started to volunteer his time at Khan Academy, and is now the lead developer. In-between providing a free world-class education for anyone anywhere, he's graciously agreed to answer some of your questions. As usual, ask as many questions as you'd like, but please, one question per post.
With his trademark hat and beard, Dr. Robert Bakker is one of the most recognized paleontologists working today. Bakker was among the advisers for the movie Jurassic Park, and the character Dr. Robert Burke in the film The Lost World: Jurassic Park is based on him. He was one of the first to put forth the idea that some dinosaurs had feathers and were warm-blooded, and is credited with initiating the ongoing "dinosaur renaissance" in paleontology. Bakker is currently the curator of paleontology for the Houston Museum of Natural Science and the Director of the Morrison Natural History Museum in Colorado. He is also a Christian minister, who contends that there is no real conflict between religion and science, citing the writings and views of Saint Augustine as a guide on melding the two. Dr. Bakker has agreed to take some time from his writing and digging in order to answer your questions. As usual, ask as many questions as you'd like, but please, one question per post.
Reducing various items to a fine powder in one of his blenders earned Blendtec CEO Tom Dickson a cult following. One of, if not the greatest viral marketing campaigns of all time, the "Will It Blend?" series has been watched almost 221,000,000 times on YouTube. In addition to receiving many marketing awards, Tom and his blenders have been featured on The Tonight Show and the History Channel series Modern Marvels. He has agreed to take a break from pureeing household objects and answer your questions. As usual, you're invited to ask as many questions as you'd like, but please divide them, one question per post.
Better known by his stage name "The Amazing Randi", James Randi has made it his quest to "debunk psychic nonsense, disprove paranormal fakers, and squash claims of pseudoscience in order to bring the truth to the forefront." Randi worked as a popular magician most of his life and earned international fame in 1972 when he accused the famous psychic Uri Geller of being a fraud and challenged him to prove otherwise. In 1996 Randi founded The James Randi Educational Foundation (JREF) a non-profit organization whose mission includes "educating the public and the media on the dangers of accepting unproven claims, and to support research into paranormal claims in controlled scientific experimental conditions." He began offering $1000 in 1964 to anyone who could demonstrate proof of the paranormal. That amount has grown over the years, and the foundation's prize for such proof is now $1M. Around 1000 people have tried to claim the prize so far without success. Randi has agreed to take a break from busting ghostbusters and giving psychic healers a taste of their own medicine in order to answer your questions. As usual, you're invited to ask as many questions as you'd like, but please divide them, one question per post.
The recipient of nineteen honorary doctorates, and honors from three U.S. presidents, Ray Kurzweil's accolades are almost too many to list. A prolific inventor, Kurzweil created the first CCD flatbed scanner, the first omni-font optical character recognition, the first print-to-speech reading machine for the blind, the first text-to-speech synthesizer, and the first music synthesizer capable of recreating the grand piano and other orchestral instruments. His book, The Singularity Is Near, was a New York Times best seller. and is considered one of the best books about futurism and transhumanism ever written. Mr. Kurzweil was hired by Google in December as Director of Engineering to "work on new projects involving machine learning and language processing." He has agreed to take a short break from creating and predicting the future in order to answer your questions. As usual, you're invited to ask as many questions as you'd like, but please divide them, one question per post.
John "Jack" R. Horner is the Curator of Paleontology at the Museum of the Rockies, adjunct curator at the National Museum of Natural History, and one of the most famous paleontologists in the world. Known in the scientific community for his research on dinosaur growth and whether or not some species lived in social groups, he is most famous for his work on Jurassic Park and being the inspiration for the character of Alan Grant. Horner caused quite a stir with the publication of his book, How to Build a Dinosaur: Extinction Doesn't Have to Be Forever, in which he proposes creating a "chickensaurus" by genetically "nudging" the DNA of a chicken. Jack has agreed to step away from the genetics lab and put down the bones in order to answer your questions. As usual, you're invited to ask as many questions as you'd like, but please divide them, one question per post.
Jörg Sprave's day job is as a manager in the world of consumer electronics. But he has been for many years making manifest the sort of things that once filled my school notebook margins with doodles: slingshots and other devices for launching bolts, steel balls, and other stuff at high speed at targets or just into the air. (Some of his "slingshots" are hard to recognize as such; he eschews the classic American wrist-rocket braced design as well as the old Tom Sawyer forked branch in favor of things a bit more elaborate.) Thanks to the Internet, hobbies that were once obscure are now easy to follow, and Sprave's homemade slingshots are no exception; you can follow his exploits through an ongoing series of YouTube videos and a forum site that builds on these videos. He's doing it in Germany, too, where firearms may be harder to come by than in the U.S., but giant honkin' firecrackers are available (at least for part of the year), and acts accordingly. Amazingly, he has yet to lose an eye; his goggles are a wise precaution. Sprave has agreed to answer your questions about his own take on physics as a hobby. As usual for Slashdot interviews, you're invited to ask as many questions as you'd like, but please divide them, one question per post.
First time accepted submitter xkrebstarx writes "A buddy of mine recently applied to a large tech company. Before setting up a phone interview with him, the unnamed company issued a timed coding test to gauge his coding prowess. He was allotted 45 minutes to complete an undergraduate level coding assignment. I would like to ask the Slashdotters of the world if they find value in these speed-programming tests. Does coding quickly really indicate a better programmer? A better employee?"
A while ago you had the chance to ask founder of the GNU Project, and free software advocate, Richard Stallman, about GNU/Linux, free software, and anything else. You can read his answers to a wide range of questions below. As usual, RMS didn't pull any punches.
Since before all other interfaces, Enlightenment has been making computers look and feel like they're from the future. On December 21, the decade long effort to rewrite Enlightenment will see the first officially stable release. With e17 a few days away, project founder and master of X11 graphics hacking Carsten Haitzler (the Rasterman) has agreed to answer your questions. Ask as many questions as you like, but only one per post please.
Last week, you asked questions of Eugene Kaspersky; below, find his answers on a range of topics, from the relationship of malware makers to malware hunters, to Kasperky Labs' relationship to the Putin government, as well as whitelisting vs. signature-based detection, Internet ID schemes, and the SCADA-specific operating system Kaspersky is working on. Spoiler: There are a lot of interesting facts here, as well as some teases.
Today we're doing a live interview from 18:30 GMT until 20:30 GMT with long time contributor Luke Leighton of Rhombus Tech. An advocate of Free Software, he's been round the loop that many are now also exploring: looking for mass-volume Factories in China and ARM processor manufacturers that are truly friendly toward Free Software (clue: there aren't any). He's currently working on the first card for the EOMA-68 modular computer card specification based around the Allwinner A10, helping the KDE Plasma Active Team with their upcoming Vivaldi Tablet, and even working to build devices around a new embedded processor with the goal of gaining the FSF's Hardware Endorsement. Ask him anything. (It's no secret that he's a Slashdot reader, so expect answers from lkcl.)
A couple of weeks ago you had a chance to ask Canonical Ltd. and the Ubuntu Foundation founder, Mark Shuttleworth, anything about software and vacationing in space. Below you'll find his answers to your questions. Make sure to look for our live discussion tomorrow with free software advocate and CTO of Rhombus Tech, Luke Leighton. The interview will start at 1:30 EST.
Eugene Kaspersky probably hates malware just as much as you do on his own machines, but as the head of Kaspersky Labs, the world's largest privately held security software company, he might have a different perspective — the existence of malware and other forms of online malice drives the need for security software of all kinds, and not just on personal desktops or typical internet servers. The SCADA software vulnerabilities of the last few years have led him to announce work on an operating system for industrial control systems of the kind affected by Flame and Stuxnet. But Kaspersky is not just toiling away in the computer equivalent of the CDC: He's been outspoken in his opinions — some of which have drawn ire on Slashdot, like calling for mandatory "Internet ID" and an "Internet Interpol". He's also come out in favor of Internet voting, and against SOPA, even pulling his company out of the BSA over it. More recently, he's been criticized for ties to the current Russian government. (With regard to that Wired article, though, read Kaspersky's detailed response to its claims.) Now, he's agreed to answer Slashdot readers' questions. As usual, you're encouraged to ask all the question you'd like, but please confine your questions to one per post. We'll pass on the best of these for Kaspersky's answers. Update: 12/04 14:20 GMT by T : For more on Kaspersky's thoughts on the importance of online IDs, see this detailed blog posting.
Richard Stallman (RMS) founded the GNU Project in 1984, the Free Software Foundation in 1985, and remains one of the most important and outspoken advocates for software freedom. RMS now spends much of his time fighting excessive extension of copyright laws, digital rights management, and software patents. He's agreed to answer your questions about GNU/Linux, free software, and anything else you like, but please limit yourself to one question per post.
In addition to founding Canonical Ltd., the Ubuntu Foundation, and funding the Freedom Toaster, Mark Shuttleworth is a space enthusiast. In April 2002 Mark became the second self-funded space tourist and the first African in space. He spent eight days participating in experiments on the International Space Station as part of his $20 million trip. Now he's ready to answer your questions. Ask him anything you like, but please limit yourself to one question per post.
Phil Shapiro isn't famous, but he's a pretty good writer whose work appears regularly at opensource.com. He makes his living as the tech support person (he calls it "public nerd") at the Takoma Park Maryland Library. He has also -- see the link to his bio page above -- lived in New Delhi, India; Copenhagen, Denmark; Paris, France; and Scarsdale, New York. He got started with Linux as a "social justice" thing; because Linux and FOSS helped make it possible for people of modest means (we used to just call them "poor") to learn about computers and get on the Internet. He's still a big "computer for the masses" advocate and computer rehab volunteer. What's especially interesting about this interview (which is slightly out of sound/visual synch; you may prefer reading the transcript) is the amount of credit Phil gives Slashdot for spurring him on and getting him excited about FOSS. He also sees Slashdot as instrumental in helping start the Maker subculture. Do you agree? If so, should influencing the future of technology be Slashdot's main mission? Also: If so, how do you suggest we do it? And more specifically, do you know any other non-famous Slashdot readers (or people in general) we should talk to because they are doing interesting things?
In part 2 of this video interview (with transcript), Dr. Richard Dawkins explains the function of the Richard Dawkins Foundation for Reason and Science, headlined by his website. They're holding it up as a blueprint for similar groups: "We're trying to encourage, with some success, other organizations to make use of our facility, so that they will use our website, or have their own websites which are based upon ours, and have the same look and feel and use the same infrastructure." One of the Foundation's other purposes is to oppose organizations like the Good News Club. "What it is, is a group of Fundamentalist Christian organizations, who go into public schools after the school bell has rung for the day. So that it's no longer violating the Constitutional separation of church and state. ... And it's actually the Good News Club people masquerading as teachers, and they're being extremely effective." Dr. Dawkins also talks about his own comments, and explains why they're perceived as offensive: "Ignorance is no crime. There are all sorts of things I'm ignorant of, such as baseball, but I don't regard it as insulting if somebody says I'm ignorant of baseball, it's a simple fact. I am ignorant of baseball. People who claim to be Creationists are almost always ignorant of evolution. That's just a statement of fact, not an insult. It's just a statement. But it sounds like an insult. And I think that accounts for part of what you've picked up about my apparent image of being aggressive and offensive. I'm just telling it clearly." Hit the link below to see the rest of the interview.
In this video interview (with transcript), Dr. Richard Dawkins discusses religious exceptionalism with regard to the teaching of evolution, and the chilling effect of fundamentalism on the production of scientists and engineers. He says, "I can think of no other reason why, of all the scientific facts that people might disagree with or disbelieve, [evolution] is the one they pick on. Physics gets through OK. Chemistry gets through Ok. But not biology/geology, and I think it's got to be because of religion." He also addresses the recent comments from Rep. Paul Broun, who denounced evolution and the Big Bang theory as "lies straight from the pit of hell," and the recent Innocence of Muslims video that led to unrest in various parts of the world. "Freedom of speech is something that Islamic theocracies simply do not understand. They don't get it. They're so used to living in a theocracy, that they presume that if a film is released in the United States, the United States Government must be behind it! How could it be otherwise? So, they need to be educated that, actually, some countries do have freedom of speech and government is not responsible for what any idiot may do in the way of making a video." He also has some very insightful comments about religion as one of the most arbitrary labels by which people divide themselves when involved in conflict. Hit the link below for the video.
You asked Daniel Knight, director of the crowd-funded filmed version of Terry Pratchett's Troll Bridge, about cameras, Kickstarter, and his source material. Daniel's answered now with details on the process of filming, why they selected Troll Bridge, and his favorite He-Man figurines. Read on below!
Richard Dawkins is an author and an evolutionary biologist. For 13 years, he held the Simonyi Professorship at the University of Oxford. His 1976 book The Selfish Gene helped popularize the gene-centric view of evolution and coined the word "meme." Several other of his books, including Climbing Mount Improbable, River Out of Eden, and The Greatest Show on Earth have helped to explain aspects of evolution in a way non-scientists can more easily understand. Dawkins is a frequent opponent of creationism and intelligent design, and he generated widespread controversy and debate in 2006 with The God Delusion, a book that subjected common religious beliefs to unyielding scientific scrutiny. He wrote, "One of the truly bad effects of religion is that it teaches us that it is a virtue to be satisfied with not understanding." Most recently, Dawkins wrote The Magic of Reality: How We Know What's Really True, a graphic book that aims to introduce kids to science. He's also recently begun a video series titled "Sex, Death, and the Meaning of Life" about how our world would look without religion. Mr. Dawkins has graciously agreed to answer some questions for us. Post your suggestions in the comments below, but please limit yourself to one question per post. We'll post his responses sometime next week.
At this summer's HOPE, Eben Moglen was one of the most incisive and entertaining speakers. But since only a small fraction of the Earth's population can fit into an aging hotel meeting room, you can watch his HOPE presentation via Archive.org on making the first law of robotics apply to cell phones. Besides being a professor at Columbia Law, former clerk in U.S. federal court as well as to Supreme Court Justice Thurgood Marshall, and a prolific writer, Moglen is founding director of the Software Freedom Law Center as well as the creator of the FreedomBox Foundation, and was for many years general counsel of the Free Software Foundation. Moglen has strong opinions, and a lot to say, about software licensing and freedom, copyright, patents, and (as you can see from the video linked above) about the privacy implications of always-on, always-on-us technology. Next week, I'll be meeting up with Moglen for a short interview. If you have a question for Eben, please post it below; I can't guarantee how many reader questions I'll have a chance to ask him, but the more, the merrier.
Monday you had a chance to ask Linus Torvalds any question you wanted. We sent him a dozen of the highest rated and below you'll see what he has to say about computers, programming, books, and copyrights. He also talks about what he would have done differently with Linux if he had to do it all over again. Hint: it rhymes with nothing.
Linus Torvalds was (and still is) the primary force behind the development of the Linux kernel, and since you are reading Slashdot, you already knew that. Mr. Torvalds has agreed to answer any questions you may have about the direction of software, his thoughts on politics, winning the Millenial Technology Prize, or anything else. Ask as many questions as you'd like, but please keep them to one per post. We'll send the best to Linus, and post his answers when we get them back. Remember to keep an eye out for the rest of our upcoming special interviews this month.
He co-founded Apple Computer, he's a programmer and engineer who invented the Apple I and Apple II computers, he's one of our most influential readers, he is known simply as Woz. To kick-off our 15th anniversary month, Woz has agreed to take some time to answer a few of your questions; as with other Slashdot interviews, you're invited to ask as many questions as you'd like, but please ask them in separate posts. We'll be running a number of other special interviews this month, so keep your eyes open.
Daniel Knight, besides being an actor, D&D fanatic, and collector of He-Man figurines, is the director of a film version of Terry Pratchett's Discworld story Troll Bridge that's been enabled by a massive Kickstarter campaign. Filming has finished (you can see some of the raw and intermediate footage linked from that story) and now all the rest of the work that goes into the finishing and releasing the movie is underway. Why this film? Knight says he "ended up acting a small role in a short film called Star Wars: Broken Allegiance. My performance was terrible. But that introduced me to the world of fan films, and I started wondering if it would be possible to do a Discworld one." The project is clearly a labor of love — it's a massive undertaking on a shoestring budget, with a tough goal: "Troll Bridge aims to be the largest scale short film in history. Using resources garnered over eight solid years of dedication, love, sweat, and tears – Troll Bridge has already begun exceeding expectations as to what should be anticipated from a short form production." The cast and crew (even the caterers) are all volunteers, but it still takes money to construct sets, create costumes, and buy time with needed equipment. Daniel has graciously agreed to answer your questions about the process; as with other Slashdot interviews, you're invited to ask as many questions as you'd like, but please ask them in separate posts.
You asked questions about the LHC (and in particular, the believed discovery of the Higgs Boson) of physicist Giovanni Organtini. Organtini has responded (answers below), and written a brief introduction to explain what the Higgs boson is and how it provides mass to other particles: "The Higgs mechanism was introduced to explain the fact that experimentally particles have mass. In fact, without the Higgs mechanism, the equations of motion for particles can only be written for massless particles. The actual mechanism is rather difficult to understand without a solid Quantum Field Theory background, but can be understood as follows: most of you know that particles gain some energy when they interact with a field. As an example, consider a book on a table. Since the book is subject to the earth's gravitational field, it has some potential energy that transforms into kinetic energy if it is free to fall. The potential energy depends on the mass of the book and on the intensity of the gravitational field. With the introduction of Special Relativity, however, we have to add an extra term to the energy of the book depending on its mass only (the famous E=mc^2). Introducing a special field (the Higgs field), we can turn this term into something similar to the gravitational potential energy, i.e. something that contributes to the energy of the book because it interacts with a field. The mass of a particle, then, is nothing but its potential energy in the Higgs field. The Higgs field is auto-interacting, i.e. it interacts with itself, as the electric and magnetic fields do. As the electromagnetic field can, the Higgs field can also propagate through space, but since it's auto-interacting, it gains some energy from itself, as the book gains energy from the interaction with it, resulting in the appearance of a mass for such a field, that becomes observable as a particle called the Higgs boson. You can find a more formal, yet simple, explanation of the mechanism here." Read on for his answers to reader questions.
Joseph Palaia is an entrepreneur, engineer and technologist who is working on creating the first permanent settlement on Mars. In 2009, he served as executive officer and chief engineer for a one-month simulated Mars mission at the Mars Society's Flashline Mars Arctic Research Station on Devon Island in the Canadian arctic. He has played an integral role in two commercial design studies of the first permanent Mars settlement. He is co-author of technical papers on the topics of Mars nuclear power plant design, Mars settlement architecture, space economics and the economics of energy on Mars. In addition to his work on inhabiting Mars, Joseph is also the Chief Operating Officer & Director of Earthrise Space, Inc. ESI is a research laboratory whose goal is to design, build, and operate spacecraft with the help of students. They are currently working on both a lunar lander and lunar rover for the Google Lunar X Prize. Joseph has agreed to take off his spacesuit and answer any of your questions about building moon machines with students, long-term survival in space, and all things Kuato related. Ask as many questions as you like, but please confine your questions to one per post.
Giovanni Organtini of Italy's National Institute of Nuclear Physics (well, Instituto Nazionale di Fisica Nucleare) has agreed to answer questions about the recent observations of a particle consistent with the Higgs Boson. Dr. Organtini is part of the CMS experiment at the Large Hadron Collider. He is careful to note that while the researchers "[believe] that this new particle, with a mass 125 times that of a proton, is the famous Higgs boson," they "need to study that new particle more deeply in the next months to be conclusive on that. Organtini likes free software (he's written Linux device drivers, too) and has his own physics-heavy YouTube channel, mostly in Italian. Please confine questions to one per post, but feel free to ask as many as you'd like.
Dr. Ramsey Faragher graduated from the University of Cambridge in 2004 with a first-class degree in Experimental and Theoretical Physics. He then completed a PhD in 2007 at Cambridge in Opportunistic Radio Positioning under the direction of Dr. Peter Duffett-Smith, a world expert in this field. He is now a Principal Scientist at the BAE Systems Advanced Technology Centre specializing in positioning, navigation, sensor fusion and remote sensing technologies in the land, air, sea and space domains. We recently covered his NAVSOP project, an advanced positioning system that exploits existing transmissions such as Wi-Fi, TV, radio and mobile phone signals, to calculate the user’s location to within a few meters. Dr. Faragher has graciously agreed to answer any questions you may have about NAVSOP, the future of GPS, or what a theoretical physicist puts on his business card. Ask as many questions as you like, but please confine your questions to one per post.
NASA's been solicited ideas for exploring Mars, but Dutch entrepreneur Bas Lansdorp is already planning a different kind of trip than is likely to come from the U.S. government. Lansdorp's Mars One project has the goal of putting humans on Mars in 2022, with a twist that might dampen many people's hopes to be a Mars-exploring astronaut: the trip Lansdorp plans is one-way only. That means dramatically less fuel on board, because unlike typical Mars voyage plans, there would be no need (or ability) to carry the mechanism or the energy storage to return to Earth. If you (and three close companions) are willing to go be the first people to die on Mars, you'll also need to give up more than a pinch of privacy, because the Mars One plan to obtain the necessary funding is straightforward: create a media spectacle, and monetize it through advertising. (Note: If Elon Musk's optimistic sounding predictions are right, maybe one-way Marstronauts can get a return ticket, after all.) Many questions about the proposed journey are answered in the project's FAQ; check there before formulating questions. Ask Lansdorp about the practicalities and impracticalities of reaching Mars with as many questions as you'd like, but (lest ye be modded down) please only one question per post.
Last week, you asked questions of Vermont Senate candidate Jeremy Hansen, running on an unusual platform: Hansen pledges to take advantage of modern communications if elected, and (with exceptions he outlines in his answers) vote based on the opinion of his district's voters on a per-issue basis. Read below Hansen's answers about such a system could work; he addresses concerns about security, practicality, morality, and more. "Before I start with the answers," he writes in introduction, "I want to clear a few things up. I am running as an independent for a Vermont Senate seat, not the U.S. Senate, so questions about classified and similar material do not (for the most part) apply. Also, for everyone's reference, there are 44,000 registered voters in Vermont's Washington County Senate district. Many of the concerns about managing input from very large populations are not as applicable here." Read on for more.
Last week you got a chance to ask the team behind Space Command about their project and all things sci-fi. Marc Zicree, Doug Drexler, David Raiklen, and Neil Johnson were nice enough to put down the blasters and answer a handful of your best questions. David even answered one of his own! Read below to see what they had to say.
Marc Zicree, Doug Drexler, David Raiklen, and Neil Johnson are the guys behind the fastest funded film project ever on Kickstarter, Space Command. The project will feature a number of Star Trek vets behind the camera and a number of Trek actors are also involved, including Armin Shimerman, George Takei, Ethan Phillips and Robert Picardo. The team has graciously agreed to take some time from trying to make a crowd-funded movie, building spaceships, and exploring alien worlds to answer your questions. Ask as many as you like but please confine your questions to one per post.
We mentioned yesterday Jeremy Hansen's run for the Vermont Senate. There are a lot of political races currently active in the U.S.; what makes Hansen's interesting (besides his background in computer science) is his pledge to use modern communication technology to provide a taste of direct representation within a representative democracy. He makes a claim not many candidates (and probably even fewer elected officials) ever will: "A representative should be elected who would work strictly as an advisor and make all policy and voting decisions based on the will of his or her constituents, regardless of personal opinion." To that end, Hansen says that if he's elected, he'll employ "an accessible online voting platform to allow discussion and voting on bills" for his constituents. He's agreed to answer questions about how such a system could work, and the nature of democracy in today's ultra-connected world, in which distance and communication delays are much smaller than they were even 20 years ago, never mind 200. So ask Hansen whatever questions you'd like about his plans and philosophy; as always, ask as many questions as you please, but please separate them into separate posts, lest ye be modded down.
You recently got the chance to ask a group of MIT researchers questions about fusion power, and they've now finished writing some incredibly detailed answers. They discuss the things we've learned about fusion in the past decade, how long it's likely to take for fusion to power your home, the biggest problems fusion researchers are working to solve, and why it's important to continue funding fusion projects. They also delve into the specifics of tokamak operation, like dealing with disruption events and the limitations on reactor size, and provide some insight into fusion as a career. Hit the link below for a wealth of information about fusion.
kodiaktau writes "Salary.com profiles 14 questions that interviewers may or may not ask during the interview process such as the standards of age, gender and sexual orientation. They also profile several lesser known illegal or border line questions like height/weight, military background, country of origin and family status. With the recent flap over companies asking potential employees for passwords during the interview process it is important to know and review your legal rights before entering the interview. Have you been confronted with borderline or illegal interview questions in the past? How have you responded to those questions?"
Nuclear fusion power is the process of fusing light nuclei together to release energy, and ultimately, to put electricity on the grid. Today, we have six researchers from MIT's Plasma Science and Fusion Center here to answer your questions about fusion power, tokamaks, and public support and funding in the U.S. for this research. The Obama Administration's budget request for fiscal year 2013 is paying for the U.S. share of ITER construction out of the domestic program, starting with the closure of the MIT fusion lab. The interviewees are ready to answer technical and policy questions, so don't be shy! And, as always, please break unrelated questions into separate posts. Read on for information about the researchers who will answer your questions.
A few weeks back, you asked gaming-world academic and game designer Ian Bogost questions from the business, philosophical, and aesthetic sides of gaming; below, find his responses. Thanks, Ian!
You asked Carl Malamud about his experiences and hopes in the gargantuan project he's undertaken to prod the U.S. government into scanning archived documents, and to make public access (rather than availability only through special dispensation) the default for newly created, timely government data. (Malamud points out that if you have comments on what the government should be focusing on preserving, and how they should go about it, the National Archives would like to read them.) Below find answers with a mix of heartening and disheartening information about how the vast project is progressing.
If you've ever tried to look up public records online, you may have run into byzantine sign-up procedures, proprietary formats, charges just to view what are ostensibly public documents, and generally the sense that you're in a snooty library with closed stacks. Carl Malamud of Public.Resource.Org has for years been forging a path through the grey goo of U.S. government data, helping to publicize the need for accessible digital archives — not just awkward, fee-per-page access. (Mother Jones calls him a "badass.") Malamud has (with help) been making it easier to get to the huge swathes of data in government sources like PACER, EDGAR, and the U.S. Patent Office. He's got a new initiative now to establish a "Federal Scanning Commission," the task of which would be to assess the scope and outcomes of a large-scale effort to actually digitize and make available online as much as practical of the vast holdings of the U.S. government. ("If we were able to put a man on the moon, why can't we launch the Library of Congress into cyberspace?") Ask Malamud below questions about his plans and challenges in disseminating public information. (But please, post unrelated questions separately, lest ye be modded down.)
Ian Bogost is a professor of game theory at Georgia Tech, a game designer, a prolific writer, an entrepreneur, and a bit of a prankster. These roles which sometimes overlap, notably in his surprise success satirical Facebook game Cow Clicker, which you can think of as the Anti-Zynga. Wired has a fresh article up about Bogost (which cleverly embeds a sort of micro version of Cow Clicker). It also mentions another game — my favorite of his projects — that should be on the mind of every TSA employee, the 2009 release Jetset. Ask Ian about clicking cows, being an academic provocateur as well as a participant in the world of gaming, and breaking into the world of social gaming. (Please break unrelated questions into multiple comments.)
A few weeks ago you asked security guru Moxie Marlinspike about all manner of security issues, being searched at the border, and how to come up with a good online name. He's graciously answered a number of your inquiries which you will find below.
Greg Leyh is an electrical engineer who has spent most of his career working around particle accelerators and high-voltage machinery. Recently Leyh has been working on The Lightning Foundry, a project to see if humans can replicate the voltage economy effect of lightning. With the help of a Kickstarter campaign and a pair of 10-story Tesla Coil towers he hopes to generate man-made lightning. Greg has agreed to take some time away from his lightning machines and answer your questions. Ask as many as you like but please confine your questions to one per post.
As a security researcher, Moxie Marlinspike has played a big role in explaining what can go wrong in using Certificate Authorities to authenticate SSL traffic, an issue that's been top of mind this year thanks to compromised and faked certificates. On that front, he's lately come up with a system designed to circumvent CAs entirely, which means bypassing compromised (or invidious) authorities, rather than trying to patch the CA system. Another line of research, but not the only one, is mobile security and privacy; his Whisper Monitor Android firewall, released earlier this year, gives Android users notifications (and fine-grained permissions) when apps — including location-tracking or malware apps — want to make outbound connections. Possibly related: Moxie can also speak first-hand about what new border-search policies mean for travelers, having had his laptop and phones seized on returning to the U.S. from a trip. (And by the way, he's also an accomplished sailor and film-maker.) Moxie's agreed to answer your questions. Ask as many questions as you'd like, but please, be kind of rewind^wask don't ask unrelated questions in the same post.
