Last week we announced that co-founder and CEO of Intellectual Ventures, Nathan Myhrvold, had agreed to do a live Q&A. Earlier today we posted a few of his answers, but now's your chance to hear it directly from him. Mr. Myhrvold will be answering your questions below until 12:30 PDT. Please keep it to one question per post so everyone gets a chance. Update: 04/03 19:41 GMT by S : 12:30pm PDT has come and gone, and Mr. Myhrvold has to move on. Thanks for the answers! Here's a link to his user page if you'd just like to read his responses.

Last week you had a chance to ask co-founder and CEO of Intellectual Ventures, Nathan Myhrvold, questions before his live Q&A. Below you'll find his answers to a few of the highest rated. Make sure you come back today from 12-12:30pm PDT (3-3:30pm ET, 19:00-19:30 GMT) to ask him whatever you like in real time. We'll have a new story for your questions at that time.

Here's a corporate motto for you: "Destroying data since 1959." Timothy ran into a company called Garner Products (which doesn't use that motto as far as we know), at a security conference. While most exhibitors were busily preserving or encrypting data one way or another, Garner was not only destroying data but delighting in it. And yes, they've really been doing this since 1959; they started out degaussing broadcast cartridges so broadcasters could re-use them without worrying about old cue tones creeping into new recordings. Now, you might ask, "Instead of spending $9,000 or more to render hard drives useless, couldn't you just use a $24 sledge hammer? And have the fun of destroying something physical as a free bonus?" Yes, you could. You'd get healthy exercise as well, and if you only wanted to destroy the data on the hard drives, so what? New drives are cheap these days. But some government agencies and financial institutions require degaussing before the physical destruction (and Garner has machines that do physical destruction, too -- which is how they deal with SSDs). Garner Products President Ron Stofan says in the interview that their destruction process is more certain than shooting a hard drive with a .45. But neither he nor Tim demonstrated a shooting vs. degaussing test for us, so we remain skeptical.

A while ago you had the chance to ask James Randi, the founder of The James Randi Educational Foundation (JREF), about exposing hucksters, frauds, and fakers. Below you'll find his answers to your questions. In addition to his writings below, Randi was nice enough to sit down and talk to us about his life and his foundation. Keep an eye out for those videos coming soon.

What the Leap Motion product (they only have one right now) does is allow you to control your computer with gestures. We're not talking about just jumping around, but "painting" on the screen with your fingers (or even chopsticks) with fine enough control that Autodesk and other drawing-orientd software vendors are working to make applications compatible with the Leap Motion Controller. And game developers? You bet! Lots of them -- and this is for a device that's not even supposed to start shipping until May 13. But, says CEO Michael Buckwald, they already have "hundreds of thousands of pre-orders," so it looks like they are developing a large market for developers (over 12,000 are in the Leap Motion developer program -- out of 50,000 who applied) so it's possible that Leap Motion could become a pretty big deal. (You can see the Leap Motion Controller in action at the end of the video.)

He was the CTO at Microsoft, is an accomplished nature and wildlife photographer, and his cookbook Modernist Cuisine won a James Beard award, but Nathan Myhrvold is probably best known for being co-founder and CEO of Intellectual Ventures. In 2009 the company launched a prototyping and research laboratory called Intellectual Ventures Lab. The lab has hired many prominent scientists to work on a variety of inventions including safer nuclear reactor designs and vaccine research. Under Myhrvold's direction Intellectual Ventures has purchased 40,000 patents and applications and internally developed over 2000 inventions, but not without controversy. Nathan has agreed to take some time to answer your questions but please limit yourself to one question per post. As a bonus on Wed. April 3, Nathan will be doing a live Q&A from 12-12:30pm PDT.

A year ago James Cameron made history by traveling solo almost seven miles deep in an area of the Pacific Ocean known the Mariana Trench’s Challenger Deep. He made the trip in a submersible he helped design, the Deepsea Challenger submersible system and science platform. To celebrate the anniversary, Cameron is forming a partnership with Woods Hole Oceanographic Institution (WHOI), and donating the Deep Sea Challenger. From the press release: "Cameron will transfer the Deepsea Challenger to Woods Hole, where WHOI scientists and engineers will work with Cameron and his team to incorporate the sub’s numerous engineering advancements into future research platforms and deep-sea expeditions. This partnership harnesses the power of public and private investment in supporting deep-ocean science. “The seven years we spent designing and building the Deepsea Challenger were dedicated to expanding the options available to deep-ocean researchers. Our sub is a scientific proof-of-concept, and our partnership with the Woods Hole Oceanographic Institution is a way to provide the technology we developed to the oceanographic community,” says Cameron. James even sent us a few early drawings of the Deepsea Challenger that he made during a conversation with oceanographer Don Walsh in November 2003. The sketches are proof that many great ideas start out on napkins or lined paper.

For many decades, gramophone records (the black vinyl discs in Grandma's attic) were made by cutting grooves directly into an acetate disc, then making a mold from that "master" and "pressing records." Nowadays, of course, we use digital recording software on our computers or even on our mobile phones. Vinyl? Strictly for fogies and maybe a few audiophiles who think analog recordings have a depth and warmth that CDs and MP3s lack. Naturally, SXSW is a haven for these folks, and among them Tim Lord found Wesley Wolfe and two German compatriots from vinylrecording.com, busily demonstrating their vinyl recording system, which is sort of the gramophone record equivalent of print on demand. Lots of background music in the video makes the voices a bit hard to hear; some might prefer the transcription -- although those who do will lose out on watching the vinyl recording machine in action. Either way. Or both. Up to you.

ICANN.org says, "The DotOrg Foundation [update: Note that the organization is now known as the Public Interest Registry], along with its operating partners, is committed to stable, efficient and affordable management of the .org registry." Most of us don't spend a lot of time thinking about the Internet's basic "plumbing," and few spend much time thinking about .org and the group that is responsible for maintaining it. That group did, however, have a booth at SXSW. That's where Timothy Lord interviewed .org spokesperson Thuy LeDinh, who was happy to explain what the .org people do and why they do it.

The guy who came up with the LazyHusband app, Ethan Duggan, isn't married. That's good, because he's only 12 years old. One of his local (Las Vegas) TV stations says this about him: "...the 12-year-old from Henderson, Nev., said he was tired of always replying to his mother's questions of how she looked in an outfit, he came up with common phrases that, with a touch of the screen, can tell his mother, 'You look amazing today.'" The app costs 99 cents for iOS, Android or Kindle. Ethan admits that Dad helped, but says the app is his own work and was his idea. He's now working on Lazy Kid and Lazy Wife. The TV story says, "Phrases for Lazy Kid include, yes, I did my homework and I love you. Ethan said he is having a hard time coming up with common phrases that a wife might say to her husband." Pro basketball retiree turned business guy Shaquille O'Neal is reportedly interested in LazyHusband, which means you may hear plenty more about LazyHusband and the prodigy who created it.

It's Austin, where people are proud to be weird -- and are more environmentally aware and more concerned about energy use than in the rest of Texas. Add SXSW, with its combination of techies, musicians, film people, and general hipsters. What could be more natural at SXSW than combining a pedicab (called a bicycle rickshaw in Old Delhi and other Indian cities) with Uber's smartphone-based dispatch system? Hook Uber up with local pedicab company Easy Rider, get Samsung to sponsor it all, and you are environmentally conscious, high tech, and (possibly) hip all at once. Totally Austin. Totally SXSW. And totally promotional for all three companies involved.

XWWT writes "A few weeks ago Make offered to send us a sample of its Raspberry Pi Starter Kit to see if we would do a review of the product. Samzenpus asked around the engineering team to see if there was someone who would be willing to do an on-camera review of the device. With all of the buzz about Raspberry Pi, I was very excited to get hands-on time with the device so I could more closely examine the platform. At first we wanted to do this piece as a video but quickly realized that a) it would probably be boring to see some blinky lights and push buttons working on a sample project, and b) the amount of audio that would need to be bleeped to cover my frustration with parts of the kit would be annoying. On a personal note, I also wanted to document all of my experience here as I thought it would be beneficial for newcomers to the maker technology and sometimes having someone else’s experience documented can help you avoid pitfalls and mistakes. (Full Disclosure: I am the Director of Engineering for Slashdot Media. We were given a review copy of the Make: Raspberry Pi Starter Kit. We were not paid for this review but had fun doing it.)" Keep reading for the rest of Wes's review.

A while ago you had a chance to ask blender aficionado and internet celebrity Tom Dickson about viral marketing, and all things blended. Below you'll find his responses to your blender inquiries.

In a way, this app is nothing but a cute gimmick. There are many apps that allow you to make panoramic photos on an iPhone, not to mention the panorama feature built into iOS6 -- and plenty for Android, too. But Cycloramic makes your iPhone spin around while standing on edge (on a smooth surface), which is a fine stunt and a great party trick. And it's endorsed by Steve Wozniak, which is a boast few iPhone apps can make. He calls it "Unexpected, fanciful, and useful all at the same time!" Even if it had no practical value whatsoever, you might want to blow 99 cents on Cyclorama just to watch your phone make you dizzy. Most Android phones won't stand on edge. (Tim's won't and neither will mine.) So an Android version would require a stand. Or at least a pattern so we could make our own stands out of cardboard or sheet plastic. But that's a "maybe," and apparently not likely to come along soon. For the moment we'll just have to envy iPhone owners as their phones magically spin around, taking photos now and then as they turn.

Slashdot editor Tim Lord was wandering around SXSW and ran into a small display for Lynx Laboratories, a startup that makes this claim about its Lynx A camera: "If you can use a point-and-shoot Nikon, you'll find the Lynx even easier to use. Instead of outputing 2D images, it produces 3D models of whatever you point it at. It's faster and cheaper than existing solutions today." There's a two-minute demo at the end of the video in which Lynx Founder and CEO Chris Slaughter shows how it works, and (at least in his hands) it looks extremely easy. The company is a University of Texas spinoff that "has received prestigious awards including the 1st Place Idea2Product (I2P) Texas, 1st Place I2P Global, Top 10 Dell Innovators and National Science Foundation Small Business Innovation Research Funding." Naturally, they're hoping to raise money through Kickstarter as well. They're looking for $50,000 and as of 13 March 2013 it looks like they've raised $88,548 of it. There are obviously other ways to make 3-D images and models. But Lynx seems to have made a novel device, and the images it makes can be picked up directly by a number of 3D printer software packages. The Lynx-A also does motion capture, which could really speed up rotoscoping and other techniques that make video games and other animations look more lifelike than pure animation. That's totally different from static 3D modeling but might be more interesting to more people, at least in a commercial sense.

Yesterday we ran the first half of Dr. Robert Bakker's essay in response to your questions. Below you'll find the second part which focuses on the history of science and religion, and the patron saint of paleontology, St. Augustine of Hippo. A big thanks goes out to Dr. Bob for his lengthy reply.

SXSW Create is one of a handful of sub-shows at SXSW which don't require an expensive badge — it's maker-oriented and small, and a few blocks from the slicker parts of the convention. (The local ATX Hackerspace was there showing off robots and giving out soldering lessons and blinkies, without a single corporate pitch.) Under the same tent, I met with Jeff McAlvay, co-creator of Board Forge, which Jeff hopes will make small-run circuit board creation as easy and accessible as small-scale 3-D printing has become in the last few years. ("Think MakerBot for electronics.") The prototype hardware McAlvay had on hand looks -- in fact, is a 3-D printer, albeit one lower-slung than the ones that make plastic doo-dads. That's because the Board Forge's specialized task of assembling circuit boards requires only limited vertical movement. It's using the open-source OpenCV computer vision software and a tiny camera mounted on a movable head to accomplish the specialized task of selecting and placing components onto the boards. The tiny electronic components are lined up in strips on one side of the device, where that smart head can grab them for placement. The brains of the operation include an Arduino-family processor for basic controls, and a Raspberry Pi for the higher-level functions like computer vision. The projected cost for one of these machines — about $2000 — should put instant-gratification machine-aided circuit creation in reach of schools and serious hobbyists, but there's plenty of work before it's set for sale to the public; look for a Kickstarter project in the next few months.

A while ago you had the chance to ask paleontologist Dr. Robert Bakker a wide variety of questions. Instead of answering them individually, Dr. Bob decided to write a lengthy piece that covers most of your inquiries, and includes personal stories and some of his philosophy. The first part is a narrative about his childhood conversion to fossil studies and how his paleo-CSI approach developed. We'll post the second half, covering his training in the history of theology and how it intersects with his science, tomorrow.

Millions of pixels have been used to talk about Yahoo! CEO Marissa Mayer's decision to ban telecommuting and her reasons for doing it. Today's interviewee, Mårten Mickos, built MySQL AB into a billion-dollar company with 70% of its workers, all over the world, telecommuting instead of working in offices. Now he's CEO of another young open source company, Eucalyptus, and is following a similar hiring pattern. Mårten says (toward the end of the video/transcript) that he believes people working out of their homes is entirely natural; that this is how things were done for thousands of years before the industrial revolution.

Spearphishing. The deluxe (but easy) way to get unwary employees to put malware on your network. It's basically the same as phishing, except more targeted. That is, a plain phishing scam might offer an unwary web-browsing employee a chance to see a famous starlet naked, while a spearphishing attack might purport to be an urgent request from your Bizzaro County office for 200 Kg of Unobtainium Oxide. Open that email, and... ZAP! So this is social hacking (cracking for the old-timers), and cannot necessarily be fought entirely by technical means. So how about setting up fake spearphishing attempts and immediately sending employees who fall for them to an IT security class with an emphasis on how to avoid phishing scams? You can do this yourself, possibly with help from a bright person or two from a nearby University. Or you can contact PhishMe or another anti-phish training company and have them help you teach spearphishing awareness to your people. Either way, every computer-using person in your company should know about phishing -- and should know how to avoid getting hooked by phishers.
