When you call your business Penguin Computer & Telephone Solutions, it's obvious that Linux is your favorite operating system. Company owner Frank Sflanga, Jr. happily works on Windows, Mac and whatever else you want or have around, but he is a Linux person at heart; in fact, he's a founder and leading member of The Southwest Florida GNU/Linux Users Group. But the point of this interview, which some will want to label an ad (although it's not), is to show how Frank started his one-man consulting business and made it successful so that other Slashdot readers can follow in his footsteps and become self-employed -- if they are so inclined. You might want to note that most of Frank's clients were not familiar with Linux when he first started working with them, and most are not particularly interested in software licensing matters as long as Frank keeps their stuff working. You might also want to note that Ft. Myers, FL, where Frank is located, is not exactly famous as a hotbed of leading-edge technology, which means that even if you live someplace similar, where business owners ask "What's a Linux?" you might be able to make a decent living running a Linux-based IT consulting business.

Famous for his work in math, astronomy, nuclear engineering, and theoretical physics, Freeman Dyson has left his mark on almost every scientific discipline. He's won countless awards, and written numerous books on a wide range of topics both scientific and philosophical. One of his biggest contributions to science was the unification of the three versions of quantum electrodynamics invented by Feynman, Schwinger and Tomonaga. 10 years after moving to the U.S. he started working on the Orion Project, which sought to create a spacecraft with a nuclear propulsion system. STNG exposed the idea of a Dyson sphere to the masses, and his hypothetical plan for making a comet habitable with the help of genetically-engineered plants is a personal favorite. Mr. Dyson has graciously agreed give us a bit of his time in order to answer your questions. As usual, ask as many as you'd like, but please, one question per post.

Last week you had the chance to ask J. Michael Straczynski (jms) about Babylon 5, his new original series, Sense8 , and all things sci-fi. Below you'll find his answers to your questions.

David Gallo is an oceanographer and Director of Special Projects at the Woods Hole Oceanographic Institution. He has participated in expeditions to all of the world’s oceans and was one of the first scientists to use a combination of robots and submarines to explore the deep seafloor. As a member of James Cameron’s Deep Ocean Task Force and the XPrize Ocean Advisory Board, David actively encourages the development of new technologies for ocean exploration. With more than 8 million views, his TED presentation entitled Underwater Astonishments is the 4th most viewed TED Talk to date. David has agreed to come up for air and answer any questions you may have. As usual, ask as many as you'd like, but please, one question per post.

StrongAuth helps protect data with strong encryption, so that even if a company's network infrastructure is breached, its critical data -- including customers' credit card numbers, for example -- is still safe. Their software is open source, and their objective is to "become like the Toyota Camry of encryption key management," says StrongAuth CTO Arshad Noor. "Everybody should be able to afford it." These are big words from a company that only has 12 employees, all in Silicon Valley, but it's a company that not only has a strong reputation among its small and medium-sized business clients, but is starting to get acceptance from Fortune 500 behemoths, too. In this video interview (and in the transcript), Arshad not only talks about data security, but about how his company makes money while developing and relying purely on open source software. And did somebody ask about Linux? Yes, their software is all based on Linux. CentOS, to be exact.

He has written for many different comic book titles including Superman and The Amazing Spider-Man, and wrote the screenplay for the Academy Award-nominated movie Changeling, but J. Michael Straczynski (jms) is probably best known as being the creator, writer, and producer of Babylon 5. Recently, jms has teamed up with the Wachowskis and Netflix to create a new original sci-fi series, Sense8, coming out in late 2014. Straczynski has agreed to take a few minutes from writing sci-fi epics in order to answer any questions you may have. As usual, ask as many as you'd like, but please, one question per post.

All reviews are opinions. In theory, they are based on a reviewer's careful test of the product. But what about enterprise software? How can a reviewer do a real-world test of a CRM program designed to run on dozens or hundreds of workstations and to be used by dozens or hundreds of people? The idea behind G2 Crowd is crowdsourcing. Not just any old crowd, but people who use or administer enterprise software as part of their jobs. In other words, experts -- who get rewards if they supply detailed reviews. Logins require a LinkedIn identity in order to prevent bogus reviews. Will G2 Crowd work? It's still in beta, and this Slashdot interview is one of the first times it has been shown to the public, in part because our interviewee, co-founder Matt Gorniak, is a long-time Slashdot reader. So what do you think? Is this a good idea? Is their business model viable? Matt sounds nervous in this interview not only because he's not a PR pro, but also because he's anxiously waiting to see what you (yes, you) think of G2 Crowd, a business he and the rest of the company's management team hope is not only viable but really takes off.

Once upon a time, people shot a kind of video called "film." And one of the most popular film camera makers was Bolex. Their 16 mm and Super 16 mm cameras were the favored tools for indie film makers, low budget TV news operations, and film schools. Sure, there were 8mm and Super 8, but they didn't give you the stunning clarity you could get with 16 mm. Besides that, carrying a Bolex was kind of like telling everyone, "Look at me! I'm a professional moviemaker!" And with the cost of processing 16 mm film back in the late 1960s and early 1970s you pretty much had to be a pro -- or at least have access to a TV station or college film lab if you wanted to do any serious movie experimentation. Obviously, times have changed. You can now buy a fairly serious camcorder at a consumer-level price. Or a DSLR that can do video -- and do depth of field tricks hardly any camcorder can match. Even so, if you are a film junkie, you just might want a Digital Bolex. Thanks to a highly successful Kickstarter campaign, it looks like you might be able to buy one before long. Too bad you can't still get Kodachrome film, which was the perfect film for your Bolex. Ah, well. RAW format digital is more or less the 21st Century equivalent of Kodachrome, so it will have to do.

This is the second of our two-part interview (part one ran yesterday) with Conjurer and Investigator (his words) James Randi, whose organization, the James Randi Education Foundation, has a long-standing offer: prove you have paranormal abilities and they'll give you $1 Million. They say they've recently made this award easier than ever to win. Note that, lower bar or no, Randi claims the last time a conjurer's illusion fooled him was many years ago, when he was very young. It was one done by the famous Chan Canasta -- and Randi claims that in the end he figured it out, anyway. So forget the $1 Million, relax, and enjoy James Randi. He's a great raconteur, so we can all be jealous of interviewer Rob Rozeboom (samzenpus) for having made this great video even as we enjoy watching it.

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.
