When he's not lecturing at Stanford or NASA, Alan Adler is working on brewing the perfect cup of coffee and engineering flying toys. His AeroPress is one of the most popular coffee brewing systems available and one of his Aerobie Pro Rings set the world record for the farthest thrown object at 1,333 feet. Alan has agreed to sit down and answer any questions you may have. As usual, ask as many as you'd like, but please, one question per post.

Collectible card games have been a prominent part of nerd gaming culture since the early '90s. Magic: the Gathering forged a compelling genre and dozens of games have followed in its footsteps. But the past two decades have been a time of technology, and Magic is a decidedly low-tech game. Like chess, it's been moved online in only the strictest emulation of real-world play. The game itself hasn't actually evolved to make use of technology. Enter Blizzard. Many of the developers at Blizzard grew up playing Magic and other CCGs, and it seemed natural that they'd want to design one of their own. But Blizzard is video game company; managing cardboard print runs and scheduling tournaments isn't exactly in their wheelhouse. Thus, we get Hearthstone: Heroes of Warcraft, an entirely digital CCG. It's currently in closed beta test, but open beta is supposedly just around the corner. In this video (with transcript) we take a look at how the game is shaping up.

Dan Rosenbaum is the editor and publisher of Wearable Tech Insider, which means he covers wearable technology every day. He's obviously a good person to chat with if we want to learn what's going on in the wearable tech world. So we did just that. The overall sense we got is that wearable tech is less of a gimmick than it was a few years ago, but isn't necessarily something all of us need quite yet. One note here: Dan is not a Google Glass fan. Watch the video (or read the transcript) to find out why.

A while ago you had the chance to ask gamer and console modder extraordinaire Ben Heck about his favorite mods, hacks, and what he sees coming in the future. Below you'll find his answers to your questions.

Arvydas Juskevicius (say that five times fast) is an independent software developer and hardware hacker based in London (which is where I got a chance to talk with him) who's decided to bring the useful LED signalling capabilities of many modern smartphones into the world of desktop or laptop computers. With his £10 BlinkStick kit (£15 pre-assembled), you get a programmable multi-color LED that's about the size of a flash memory key. Deceptively simple -- it's essentially one giant pixel, after all, which might not sound exciting when you have millions of them on a dense display surface. But that LED light is something you can use as a signal for alarms, or to tell you that you have a message from one app while another is at full-screen, or practically anything else that you can devise software to notice and react to. I get the sense that Juskevicius would prefer that people get the kit version, to help spur interest in actually soldering some hardware rather than just plugging it in. If you're allergic to paying in other than U.S. dollars, the BlinkStick is also available from Adafruit Industries. Watch the video below to see it in action.

Berin Szoka is president and founder of the tech policy think tank TechFreedom. The group promotes a wide variety of digital rights and privacy issues. Most recently, they have started a petition demanding reforms to the Electronic Communications Privacy Act (ECPA) so that law enforcement will have to get a warrant before accessing emails stored in the cloud. With so much attention paid to the NSA snooping, Berin believes that the over 25-year-old ECPA has been overshadowed and is in dire need of changes. Mr. Szoka has agreed to answer your questions about privacy and government policy online. As usual, ask as many as you'd like, but please, one question per post.

In the world of head-worn displays, Google Glass seems to lately get most of the praise as well as most of the dirty looks, though it's far from alone. At this year's DroidCon in London, I talked with Epson Europe product manager Marc-Antoine Godfroid about a very different kind of head-worn display: the Moverio BT-100. Epson's display is running a Google operating system, but it isn't competing with Glass, at least not directly. The hardware in this case is a relatively high-definition stereo display meant for immersion (whether that means information overlays or watching recorded video) hooked to an external control unit running Android, rather than the sparer, information-dashboard, all-in-one approach of Glass. One other big difference: Epson's stereo, full-color headset is cheaper than Glass, and available now. Hit the link below to see what it looks like.

Gone are the days of boring bathroom mirrors that only reflect what's in front of them. What you really need is a bathroom mirror that gives stock quotes, displays the local weather, and tells you the temperature of the water you are about to use to wash your face. Seraku Corporation is now in the process of filling that burning need and has gotten a bunch of press attention by doing so. A cynic might wonder why people who absolutely, positively must have Internet access while they shave or perform other bathroom mirror duties don't just make a wall-mounted holder for their tablets next to their pre-Internet bathroom mirrors, but that would destroy the fun of having the display built directly into the mirror, along with sensors that detect hand gestures so you can control your mirror (no doubt by asking, "Who is the fairest of them all?") without touching it with your greasy fingers. Note that this is technically not a smart mirror but a smart washbasin with a mirror attached to it. Either way, it's not available for retail sale quite yet.

By now, most Americans have either heard or learned firsthand that the Healthcare.gov website doesn't work right. Slings, arrows, and brickbats are being slung all over Washington, and Congressional representatives are busily thundering imprecations at all and sundry who were involved in putting Healthcare.gov together. If there have been any Congressional hearing focusing on how to fix the problems, though, we have not seen them. You'd think that our representatives would bring in people like today's interviewee, Todd Williams, who has written a book titled Rescue the Problem Project and runs a company that specializes in rescuing failed projects. What's more, Todd is just one of many Americans who have helped rescue projects that have gone awry. Hopefully our government has at least one of them working on Healthcare.gov by now, although we haven't heard that they've selected a strong turnaround manager and set him or her to work on the project -- and you'd think they would have told us if they had.

What ever happened to point-and-click action role-playing games? Blizzard set the standard for this genre around the turn of the century, and while a few companies have launched Diablo clones, it's been a pretty quiet market. Several years ago, a group of hardcore gamers decided to change that. They put together an independent game studio and began developing Path of Exile, an ARPG that would update and refine all of the characteristics that made the genre great. On 23 October, after a lengthy open beta period, they launched the game, opting for a free-to-play business model supported by ethical microtransactions. It's dark, freewheeling, unashamedly complex — and a lot of fun. In this video review (with transcript), we take a look at what Path of Exile has to offer.

Milverton Wallace (@milvy on Twitter) might seem an unlikely candidate to be setting up hackathons in the UK; his background is as a journalist, and he was born a few thousand miles away in Jamaica. Nonetheless, when I met up with him at last month’s AppsWorld in London, he was about to conduct another in a series of hackathons at Google’s London campus. He’s got some interesting things to say about the mechanics and reasons for putting a bunch of programmers (and/or kids who aren’t yet programmers per se) into a room, and giving them a good environment for creativity. He has some harsh words for the UK school system’s approach to computer education (which sounds an awful lot like the U.S. approach in far too many schools), and praise for efforts (like the Raspberry Pi Foundation) to bring programming to British classrooms, both earlier and with more depth. The same ideas should apply world-wide.

With her signature pink hair, MIT engineer Limor Fried has become a force in the maker movement. Last year she was awarded Entrepreneur of the Year by Entrepreneur Magazine, and her company, Adafruit Industries, did $10 million in sales. Limor has agreed to take some time away from soldering and running a new company to answer your questions about hardware, electronics, and Adafruit. As usual, ask as many as you'd like, but please, one question per post.

Copenhagen Suborbitals says their mission is "very simple. We are working towards launching a human being into space." That doesn't sound so simple, really, but they're approaching this gargantuan task with an intentionally simple approach: a small team, relatively unhampered by bureaucratic hassles, who are taking advantage of existing, off-the-shelf high-tech solutions when they make sense, and low-tech solutions when possible; if the parable of the Soviet space pencil hadn't worked its way into the mythology of space technology, it could have been based on the Copenhagen Suborbitals point of view. I talked with project co-founder Kristian von Bengston about the project's progress so far, as well as what the next steps are. Among those next steps: in summer 2014, the Suborbitals team plans to launch their HEAT2X lift vehicle loaded with the TDS-80 capsule; you can download the preliminary trajectory projections for both the launcher and the capsule.

Benjamin Heckendorn, better known as Ben Heck, has become famous for modding consoles and game controllers. Over 10 million viewers worldwide have watched The Ben Heck Show to see him create something new out of old gaming systems every week. Been has agreed to leave the Ataris alone for a while and answer your questions about console modding and gaming in general. As usual, ask as many as you'd like, but please, one question per post.

In this video, we continue our conversation with author David Craddock about his investigation into the early days of game studio Blizzard for his new book, Stay Awhile and Listen. He's joined by Dave Brevik and Max Schaefer, two of the co-founders of Blizzard North. They talk about keeping games accessible, the importance of getting the amount of background story right in Diablo, and whether the creators of these early games have any regrets about them. They also talk about designing The Butcher. (This is video part 2 of 2. The transcript of Part 1 is now available, too, if you care to go back and read it.)

Her bio says, "Esther Schindler has been writing about computers – with a particular focus on software development and open source – since the early 1990s. You’ve seen Esther’s byline in prominent IT publications, such as CIO.com, IT World, and IEEE Spectrum. She's written dozens of analyst reports for Evans Data about software development trends. Her name is on the cover of about a dozen books, including most recently The Complete Idiot’s Guide to Twitter Marketing. Esther is editor of a site for software developers, these days, while still freelancing occasionally for IT World (most recently The developer's guide to future car technology) and she writes a blog about project management." She submits her own work to Slashdot, and submits work for other writers, too. She may or may not be the most successful Slashdot submitter of all time, based on the percentage of her submissions that show up on the front page, but she is absolutely in the top 10. In this interview, she shares some of her secrets. Maybe Esther's thoughts will help you submit more successfully. (So will reading the Slashdot FAQ.)

In this video, we talk with author David Craddock about his investigation into the early days of game studio Blizzard for his new book, Stay Awhile and Listen. He's joined by Dave Brevik and Max Schaefer, two of the co-founders of Blizzard North. They talk about some of the ways in which making video games was different back in the early '90s -- and the ways it's similar to making games today. They also discuss the importance of having lively debates, and how one of those arguments led to Diablo being a real-time action game, instead of being turn-based. (This is the first half of an extended interview -- part 2 will be available on Monday.

Goodwill Industries rehabs computers and sells computer parts, at least in Austin, Texas. The Goodwill Computer Museum is a natural outgrowth of that effort. In this video, museum curator Lisa Worley takes Slashdot's Timothy Lord on a tour of the museum. Remember that TRS-80 you threw away in 1982? Well, they saved several of them to stimulate your nostalgia-based pleasure nodules. Ditto many other devices both common and rare, including a pre-Dell computer made and signed by Texas computer celebrity Michael Dell. So sit back and enjoy the ride, as Timothy does the walking and Lisa does the talking, kind of like Night at the Museum -- but without CGI dinosaurs and other life forms getting between you and the classic computers.

Jason Calacanis gained notoriety first through Silicon Alley Reporter and later for being a co-founder of Weblogs, Inc. He's now an angel investor and has a company called, LAUNCH, which holds conferences and technology related events. The upcoming Launch Hackathon will be the largest in the world with over 1,000 developers already signed up and prizes of $800k invested in two of the top ten finalists. We had a chance to sit down with Jason to talk about what makes this hackathon so special and the future of angel investing. Read below to see what he had to say.
