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.
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.
