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."

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.
