Chester Wisniewski's nakedsecurity describes Wisniewski's specialty thus: "He provides advice and insight into the latest threats for security and IT professionals with the goal of providing clear guidance on complex topics." So he's obviously someone who might know a little about preventing future Target-style security debacles. We've also interviewed tech journalist Wayne Rash about this topic, and will probably interview another security expert or two. Many Slashdot users may find all this credit card security talk boring, but for those who handle security matters for a living, especially for retailers, it's vital information. So here's Tim Lord talking with Chet, who is a recognized security expert for Sophos, one of the big dogs in the IT security field, when Chet was in Texas for the latest iteration of Security B-Sides in Austin.

Bennett Haselton writes "The city of Seattle just imposed new limits on commercial app-based ride-sharing companies like Uber and Lyft, effectively protecting taxi companies from low-cost competition in the form of smartphone apps. If other cities follow suit, could a company help ridesharers circumvent the restrictions by creating a ride-trading app, allowing drivers to earn 'miles' by driving passengers, and redeem those miles later to get rides for themselves?" Continue reading below to see what Bennett has to say.

This is a conversation with Frank Muscarello, CEO and co-founder of MarkiTx, a company that brokers used and rehabbed IT equipment. We're not talking about an iPhone 3 you might sell on craigslist, but enterprise-level items. Cisco. Oracle. IBM mainframes. Racks full of HP or Dell servers. That kind of thing. In 2013 IDC pegged the value of the used IT equipment market at $70 billion, so this is a substantial business. MarkiTx has three main bullet points: *Know what your gear is worth; *Sell with ease at a fair price; and *Buy reliable, refurbished gear. Pricing is the big deal, Frank says. With cars you have Cars.com and Kelley Blue Book. There are similar pricing services for commercial trucks, construction equipment, and nearly anything else a business or government agency might buy or sell used. For computers? Not so much. Worth Monkey calls itself "The blue book for used electronics and more," but it only seems to list popular consumer equipment. I tried looking up several popular Dell PowerEdge servers. No joy. An HTC Sensation phone or an Acer Aspire notebook? Sure. With price ranges based on condition, same as Kelley Blue Book does with cars. Now back to the big iron. A New York bank wants to buy new servers. Their old ones are fully depreciated in the tax sense, and their CTO can show stats saying they are going to suffer from decreasing reliability. So they send out for bids on new hardware. Meanwhile, there's a bank in Goa, India, that is building a server farm on a tight budget. If they can buy used servers from the New York bank, rehabbed and with a warranty, for one-third what they'd cost new, they are going to jump on this deal the same way a small earthmoving operation buys used dump trucks a multinational construction company no longer wants.

In February, 2013 Computerworld ran an article titled A new way to sell used IT equipment about MarkiTx. The main differentiator between MarkiTx and predecessor companies is that this is primarily an information company. It is not eBay, where plenty of commercial IT equipment changes hands, nor is it quite like UK-based Environmental Computer, which deals in used and scrap computer hardware. It is, rather, the vanguard of computer hardware as a commodity; as something you don't care about as long as it runs the software you need it to run, and you can buy it at a good price -- or more and more, Frank notes -- rent a little bit of its capacity in the form of a cloud service, a direction in which an increasing number of business are moving for their computing needs. Even more fun: Let's say you are (or would like to be) a local or regional computer service company and you want to buy or sell or broker a little used hardware. You could use MarkiTx's price information to set both your buy and sell prices, same as a car dealer uses Kelley Blue Book. We seem to be moving into a whole new era of computer sales and resales. MarkiTx is one company making a splash in this market. But there are others, and there are sure to be even more before long. (Alternate video link.)

samzenpus (5) writes "Founder of the computer anti-virus company McAfee Associates, John McAfee gained world-wide attention eluding Belizean authorities in the jungle. Since we last sat down with John, he's been working on a device that blocks the government's ability to spy on PCs and mobile devices, been asked by the GOP to fix Obamacare, and has seen his last name removed from his old company. The rebranding garnered this response from McAfee: 'I am now everlastingly grateful to Intel for freeing me from this terrible association with the worst software on the planet. These are not my words, but the words of millions of irate users. ... My elation at Intel's decision is beyond words." John has agreed to answer your questions. As usual, ask as many as you'd like, but please, one per post."

This is wide-ranging interview with Dev Patel and Poulomi Damany of BitYota, an Analytics as a Service startup that works specifically with MongoDB. Open Source? Not yet. But hopefully soon, they say. And why should an IT person or programmer care about marketing-oriented analytics? Because the more you know about functions in your company besides IT (such as finance, investor relations, and -- yes -- marketing), the more valuable you are as an employee. Dev also mentions the two main things he looks for when recruiting for BitYota: "One is intellect, and the other is attitude." He points out that this is not true merely of BitYota, but of any strong startup. This is all good information for any job-seeker hoping to land a spot with a startup -- and for anyone who is happy with where he or she works but hopes to earn promotions and raises, too.

J. Michael Straczynski has written Thor, World War Z, and Changeling among many other films. He created Babylon 5 and has worked on numerous comic book titles including Superman and The Amazing Spider-Man. Most recently, he has teamed up with the Wachowskis for an original Netflix sci-fi series, Sense8 . He's agreed to take a break from his busy schedule in order to answer any questions you may have. As usual, ask as many as you'd like, but please, one question per post.

It goes up, it goes down, it goes upside down and keeps on flying. We're talking about Curtis Youngblood's latest quadcopter prototype, but as his website says, "Curtis has been flying and competing with RC Helicopters since the early 1980s and is a Multi-time World Champion and Multi-time 3D Champion." This lucky dog has managed to turn his hobby into a business; he makes and sells radio controlled helicopters -- not the $60 ones from Harbor Freight, but sophisticated aerial beasts that can carry still and video cameras and could easily be used as short-range drones, except that these are hobbyists' toys -- for hobbyists who can afford to spend hundreds and even thousands of dollars, anyway. There are plenty of quadcopter kits on the market for lots less than Youngblood's creations, along with build-it-yourself guides. But these won't fly upside down. For that, you need variable-pitch rotors and sophisticated control systems. "But what about 3-D printing?" you ask. Of *course* you can use a 3-D printer to make a quadcopter. That was an inevitable development. Here are open source instructions for building one. Enjoy the ride!

Jonathan Coulton's song Code Monkey became an anthem for many programmers (not just ones with managers named Rob) and his success is proof that you really can become an internet rock star. Since we last talked, Coulton has became the house musician for the NPR show Ask Me Another and had one of his songs copied without permission, credit, or thanks by the show Glee, much to his chagrin. Jonathan has agreed to answer all your questions about music, internet stardom, and robots. Normal Slashdot interview rules apply.

RSA holds big-time annual security conferences. The 2014 U.S. edition had 25,000 attendees, Stephen Colbert as the closing keynote speaker, and a major controversy (and some anger) from potential speakers and attendees over RSA's reputed $10 million contract with NSA to make sure the company's encryption software had back doors the secretive agency could use to spy on people and companies that use RSA software. This is part of a story that might be called The Snowden Revelations if it is made into a movie, but right now it's still controversial, and enough of a bombshell in the IT security industry that F-Secure's Mikko Hyppönen decided not to speak at this year's U.S. RSA conference, followed by Bruce Schneier, DEFCON founder Jeff Moss, Princeton professor Ed Felten, and other security luminaries.

And so, TrustyCon -- the Trustworthy Technology Conference -- was born. It was a sellout, with 400 people attending at $50 a head, and another 300 on a waiting list who couldn't get in. Slashdot's Tim Lord managed to get in, and got to speak briefly with several people there, including one of the TrustyCon organizers, Joel Wallenstrom. These were crude interviews, done on a "catch as catch can" basis, and the sound in them is poor. (Google sent a camera crew and shot over seven hours of the conference speakers, which you can watch on YouTube if you want to view TrustyCon presentations in good HD with great sound.). Will there be another TrustyCon next year? According to The Register, "The conference organizers said that, at this point, the plan is to hold another get-together next year, but that a final decision will be made closer to the time."

Former chairman of VA Software and venture capitalist, Larry Augustin, co-founded VA Research in 1993 and was one of the driving forces behind the creation of Sourceforge. VA bought Andover.net in 2000, acquiring a number of media sites, including Slashdot. He serves on the board of several companies and is currently the CEO of SugarCRM. Larry has agreed to take some time and answer your questions about the world of venture capital, open source software, and surviving the dotcom bubble.

Last week you had the chance to ask ESR about books, guns, and open source software. Below you'll find his answers to those questions.

The intro to our first video interview with Pwnie Express 'Founder and CEO and everything else' Dave Porcello back in 2012 started with this sentence: 'Pwnie Express is a cute name for this tiny (and easily hidden) group of Pen Test devices.' They have more tools now, including some they've released since we mentioned them and their (then) new Pwn Pad back in March, 2013. Now they're working with Kali Linux, a distro built especially for penetration testing (and formerly known as BackTrack). In this video we have Tim Lord chatting with Dave Porcello about recent Pwnie Express happenings at RSA 2014. (If you don't see the video below, please use this link.)

Theo de Raadt was a founding member of NetBSD, and is the founder and leader of the OpenSSH and OpenBSD projects. He is currently working on OpenBSD 5.5 which would be the projects 35th release on CDROM. Even though he'd rather be hiking in the mountains or climbing rocks in his free time, Theo has agreed to answer any question you may have. As usual, ask as many as you'd like, but please, one question per post.

Author of The Cathedral and the Bazaar and The Art of Unix Programming, Eric S.Raymond (ESR) has long been an important spokesperson for the open source movement. It's been a while since we talked to the co-founder of the Open Source Initiative so ESR has agreed to give us some of his time and answer your questions. As usual, ask as many as you'd like, but please, one question per post.

A while ago you had a chance to ask composer George Sanger about making music and sound effects for games, television, and film. Below you'll find "The Fat Man's" answers to those questions.

Jason Harrington (@Jas0nHarringt0n) is a controversial blogger, frequent contributor to McSweeney's Internet Tendency, and one of the TSA's least favorite ex-employees. His descriptions of life on the job as a TSA agent caused some big waves and restarted a national discussion on security theater. Jason will be answering your questions below for the next couple of hours, or until the security line starts moving again. Please keep it to one question per post so everyone gets a chance. Update: 03/01 02:11 GMT by S : Jason has finished up for now — you can skip to his answers at his user page, or simply browse the comments to read everything. Thanks Jason for answering our questions!

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. He now spends much of his time fighting excessive extension of copyright laws, digital restrictions management, and software patents. RMS has agreed to answer your questions about GNU/Linux, how GNU relates to Linux the kernel, free software, why he disagrees with the idea of open source, and other issues of public concern. As usual, ask as many as you'd like, but please, one question per post.

Tim Lord first saw Faraday Bicycles at CES, where their bikes drew plenty of attention and a fair amount of media interest. The company ran a successful Kickstarter campaign in 2012, and 2014 is when they are starting to ship their pre-ordered bicycles and hope to get new orders for lots more. Tim's travels later took him to San Francisco, where he had a chance to visit the shop where Faraday bikes are made, and to talk with some of the people who are designing and making them. (If you don't see the video below, please use this link.)

In addition to sponsoring the work of Linus Torvalds, The Linux Foundation supports and promotes a wide variety of resources and services for Linux. Their recently released 2014 Linux Jobs Report surveyed more than 1,000 managers and corporations, finding in part, that the demand for "Linux Professionals" was up 70% from last year. Jim Zemlin is the Executive Director of the Linux Foundation and he has agreed to answer any questions that you have about the report and the state of Linux in general. As usual, ask as many as you'd like, but please, one question per post.

This is a conversation with Jeff Whitehead and Lou Montulli, respectively Vice President of Technical Operations/CTO and Chief Scientist for Zetta.net, a company that specializes in online backup and disaster recovery service. Also, while this interview was arranged without his help, in the interest of full disclosure we'd like to tell you that Zetta's CEO is Ali Jenab, who used to be CEO of Slashdot's parent company. But this discussion isn't about Ali or Zetta.net, but about data backup, and what methods are best and most cost-effective for companies ranging from home-based businesses up to enterprise operations with thousands of employees. Among other things, we discussed the importance of multiple-site storage for important data, a factor that was drilled in to us yesterday by an article titled Another Iron Mountain Fire Points Up Shortcomings of Physical Storage by long-time tech journalist Sharon Fisher. And never forget: You don't know how effective your backup and data storage arrangements are until you try to retrieve your data -- and if you don't try to retrieve data until you need it, and things don't work, you are in big trouble. (Don't see the video? Here's a link.)
