Lumo is an interactive projector. You can use it to bore people with PowerPoint slides or you can use it as a game machine. It has a built-in (low res) camera that can detect a kick (as shown at the beginning of the video) and make a (virtual) ball move as a result of that action. 'But,' you ask, 'do they have an Indiegogo campaign?' Not yet. It launches on March 23.

The Lumo projector was originally designed for commercial use at children's museums and as a trade show attention-getter -- at $10,000 a pop. The consumer version is expected to cost less than $500, according to Lumo CEO (and Slashdot interviewee) Meghan Athavale. And while she doesn't talk much about it in the interview, if you already have a computer, a projector, and a Kinect or webcam, you can buy the a stripped-down version of the company's 'interactive-floor-wall projection' software for $39, plus games or customizable game templates.

A racing enthusiast, Pam developed racing engines for GM , McLaren, and NASCAR's Dale Earnhardt Sr.. Her current role has her running a multi-national department overseeing electrified vehicles company-wide. Fletcher has agreed to take a moment out of her busy day to answer any questions you might have. As usual, ask as many as you'd like, but please, one per post.

A couple of weeks ago you had a chance to ask former Vice President of One Laptop per Child, and current Senior Director of the Global Learning XPRIZE Matt Keller about education and the competition. The XPRIZE challenges teams from around the world to develop open source software that will allow children in developing countries to teach themselves basic reading, writing and arithmetic with a Grand Prize of $10 million. Below you will find his answers to your questions.

Meet Justin Whitehead. While a lot of his contemporaries were going to college, he became an Airborne soldier. After that he went to college, became an IT technian, got some experience as a Computer Forensic Analyst, and met people who looked like they were having a good time as penetration testers. So he took some recommended classes,got hired by One World Labs, and last week at B-Sides Austin, he and coworker Antonio Herraiz gave a talk titled 'Spanking the monkey/How pen testers can do it better.

Justin is 40, an age where a lot of people in the IT game worry about being over the hill and unemployable. But Justin's little video talk should give you hope -- whether you're a mature college student, have a stalled IT career or are thinking about a career change but want to keep working with computers and IT in general. It seems that there are decent IT-related jobs out there even if you're not a youngster; and even if you didn't start working with computers until you were in your 20s or 30s.

Zach Weiner is the author and illustrator of a number of webcomics, most notably Saturday Morning Breakfast Cereal (SMBC). He's been a guest contributor to xkcd and founded the sketch comedy group SMBC Theater. His project Augie and the Green Knight, was the most funded children's book on Kickstarter, and his newest project The Gentleman's Single-Use Monocle offers readers emergency reading protection with a bit of class. Zach has agreed to step away from the comics for a bit and answer any questions you might have. As usual, ask as many as you'd like, but please, one per post.

In February we ran a video titled Rich Olson Embodies the Spirit of the Maker Movement. We aren't saying Rich is a superman, but more like everyman or, in this case, everymaker. He is a hobbyist who, like many others, shares his designs freely in the best spirit of open source. Today we have some more words from Rich that may help you if you are just starting to use a 3-D printer and similar tools either at home or in a makerspace. and a note: If you know someone we should interview, please email robinATroblimoDOTCOM.

The Vintage Computer Festival East is where you go to see working computers from the forties through the eighties. It's held at the Information Age Learning Center (InfoAge) in Wall, New Jersey, a site that is full of electronics history on its own. In addition to displays (including a number of items for sale), there are sessions on topics ranging from "Keyboard Restoration" to "Fixing what's hopelessly broken." Event volunteer Evan Koblentz, today's interviewee, says that most of the several hundred people the event draws every year come from the United States, but there are always at least a few international visitors. And if New Jersey isn't your thing, there are other Vintage Computer Festivals you might want to attend. To get current news about these events, you might want to sign up for the VCF email list.

In Texas, guns are a common sight:gun-racks are visible in the back of many pick-ups, and pistols, cannons, and rifles are part of the state's iconography. Out-of-sight guns are common, too: The state has had legal (though highly regulated) concealed carry for handguns since 1995, though -- contrary to some people's guess, and with some exceptions -- open carry of handguns is not generally legal. One thing that's definitely not a common sight, though, is a group of people manufacturing guns just outside the south gates of the Texas capitol building. But that's just what you would have encountered a few weeks ago, when an organization called CATI (Come and Take It) Texas set up a tent that served as a tech demo as much as an act of social provocation. CATI had on hand one of the same Ghost Gunner CNC mills that FedEx now balks at shipping, and spent hours showing all comers how a "gun" (in the eyes of regulators, at least) can be quickly shaped from a piece of aluminum the ATF classifies as just a piece of aluminum. They came prepared to operate off-grid, and CATI Texas president Murdoch Pizgatti showed for my camera that the Ghost Gunner works just fine operating from a few big batteries -- no mains power required. (They ran the mill at a slower speed, though, to conserve juice.)

Rocky Mountain Unmanned Systems seems to be primarily in the business of selling aerial 'copter drones ranging in price from sub-$100 up into $1000s. But there they were at the 2015 CES (Consumer Electronics Show), showing off a submarine drone and a wheeled drone. These products don't seem to be on the company's website or even on their Facebook page quite yet. Jon McBride, the person manning their CES booth, told Timothy these products would be around soon, as in February. But it looks like a bit of extra patience is in order, although you can contact Jon through the company's Facebook page (his suggestion) if you have an urgent need for an underwater or wheeled drone for your business or government agency -- or even just for fun.

The K-Board won a "Best in Show" award at CES 2015. Plus, as Timothy said, "I always like pour and stomp demos." And it's totally cross-platform. If your computer, tablet or smartphone has a USB port and (almost) any kind of music software, it works. In theory, you could hook a K-Board to your Android or iOS device and use it to accompany yourself while you sing for spare change on a downtown corner. Or noodle around to get a handle on a theme you'll use in your next major symphony. Or...?

The former Vice President of One Laptop per Child (OLPC) Matt Keller is currently the Senior Director of the $15 million Global Learning XPRIZE. The competition challenges teams from around the world to develop open source software solutions that will allow children in developing countries to teach themselves basic reading, writing and arithmetic within a 18 month competition period. After 18 months a panel of judges will evaluate the projects and announce semi-finalists. Semi-finalists will have a month to tweak their projects and/or reconfigure their teams before the judges elect the top five finalist to proceed. Each of the five teams selected will receive $1 million to field test their ideas with the eventual winners receiving the Grand Prize of $10 million. The Global Learning XPRIZE is recruiting teams now through April 30, 2015. Matt has agreed to answer any questions you might have about the competition and the future of education in general. As usual, ask as many as you'd like, but please, one per post.

Here's a quote from the CodersTrust website: 'CodersTrust is the brainchild of Ferdinand Kjærulff. As a Captain of the Danish army he served as recovery officer in Iraq after the fall of Saddam. He pioneered a recovery project with the allied forces, bringing internet and e-learning to the citizens of the region in which he was stationed. The project was a massive success and inspired him to eventually create CodersTrust – supported by Danida – with a vision to democratize access to education via the internet on a global scale.' A lofty vision, indeed. But with help from the original microfinance company, Grameen Bank, and the Danish International Development Agency (Danida), it seems to be coming true.

This video is about Dr. Saeed Darvish-Kazem and Dr. Michael Pazaratz, two MDs from Canada, who came up with a free iOS app called WeMesh that lets you share video content with iOS-owning friends in real time. You see the video and so does your friend. more or less simultaneously. Cat videos and 90s music are two categories the doctors say are especially popular on WeMesh, which only works with YouTube at the moment, a shortcoming they hope to change in the near future.

Lee Drake owns a small IT service and sales company in Rochester, New York, called OS Cubed. He was a cubicle denizen many years ago, and didn't like it. So he started his own business, first with a partner and later as the sole owner. Rochester may be part of the infamous "rust belt," but Lee seems to be doing well, to the point where he's happy to pass on some tips about how to start and grow your own IT business. While Lee's company specializes in "Microsoft solutions," his advice applies to almost any IT business -- and almost any other kind of business, too.

Stephen Wolfram's accomplishments and contributions to science and computing are numerous. He earned a PhD in particle physics from Caltech at 20, and has been cited by over 30,000 research publications. Wolfram is the the author of A New Kind of Science, creator of Mathematica, the creator of Wolfram Alpha, and the founder and CEO of Wolfram Research. He developed Wolfram Language, a general multi-paradigm programming language, in 2014. Stephen has graciously agreed to answer any questions you may have for him. As usual, ask as many as you'd like, but please, one per post.

In between nodding earnestly as hopeful exhibitors told him how wonderful their products were, Slashdot's Timothy Lord took a look at some of the less-serious displays and goings-on at CES. Some of these people and companies no doubt take themselves 100% seriously, but after grueling days patrolling the endless exhibits at this giant show, Timothy was looking at them through tired (and cynical) eyes. This short video shows some of what he saw.

One thing Timothy noticed at CES was that there were drone vendors all over the place. Drones are obviously one of the hot-hot toy/gadget trends of the moment. The Drone that won 'Best Robot or Drone in Show' was the camera-carrying, "follows you like a dog on a (Bluetooth 3) leash" AirDog. They already had a crazy-sucessful KickStarter campaign that led to a large stack of pre-orders, so don't count on getting your very own AirDog right away, even if you have $1300 to spend on one.

Today's interviewee, Viktoria Tsukanov, is one of the executives at predictive marketing company Mintigo who did a study in January, 2015 that seemed to show that large companies with female CEOs "achieve up to 18% higher revenue per employee than male CEOs." The study, titled "She’s the CEO and She’s Sensational," used financial data Mintigo collected on 20 million companies, and determined CEOs' genders by analyzing first names, so it was not subject to survey vagaries but was a straight data analysis job. Could this be a case of correlation and causation being unrelated? It's possible. It's also possible that the revenue per employee figures are affected by the fact that female CEOs are more common in healthcare and non-profit organizations, while men dominate manufacturing and construction -- and, as Viktoria pointed out in a blog post headlined "Women Just Raised the Bar. Big Time." there may be other factors at work as well.

The "18% higher revenue" figure specifically applies to companies with more than 1000 workers, while companies with fewer workers may average more revenue per employee if they have male CEOs. Besides discussing the study itself, in our interview Viktoria talks about how male employees might want to alter (or not alter) their behavior if they find themselves working for a female boss for the first time. She also discusses challenges a woman might face if she is suddenly put in charge of a heavily male IT or programming staff. Other thoughts she shares have to do with finding mentors and dealing with negative people, both of which apply to people of all genders. Interesting food for thought all around.

A while ago you had a chance to ask Executive Director of the Tor project Andrew Lewman about fighting laws and technology that threaten anonymity and the importance of privacy. Below you'll find his answers to your questions.

This Listnr is "a new listening device connected to the cloud" being developed by a team in Japan that's currently running a Kickstarter project looking for $50,000 by March 7. The other Listnr "is a free music service helping people discover the best music from independent artists on Soundcloud and Bandcamp." More accurately, that's what it was, since their last Facebook post was in 2011 and their domain name is now for sale. Today's Listnr -- the listening device one -- claims it is able to tell whether a baby it hears is laughing, crying, gurgling or trying to talk. It is supposed to respond to finger snaps, hand claps, and other audio commands. It has an open API so that you can extend its use however you like. The company, too, is working on new applications for their product. Will there be enough of them, and will they interest enough people, to make this a success? Co-Founder Rie Ehara says, "We wanted to build something using sound to enrich and delight our lives." As of today (Feb. 2), Listnr is slightly less than halfway to its Kickstarter goal, so it's still a coin-toss whether or not Listnr will succeed.
