When I was last in California, I had the good fortune to bump into Roger Nygard who agreed to be a Slashdot interview victim. He is the Director of Trekkies, 6 Days in Roswell and the recently released Trekkies 2. He's made quite a name for himself documenting some fairly extreme geek activity, and this is your chance to put him through the wringer. Standard interview rules apply: Post questions. Moderate them. We'll select the best and post Roger's answers in a few weeks.

Massively Multiplayer games have grown increasingly popular in the last few years, and one of the hottest products out there today is NCSoft and Cryptic Studios' City of Heroes. City of Heroes is currently hovering around the 180,000 player population mark, with a European launch for the game coming up fast. The lead designer of the online super hero game is Jack Emmert, veteran of the video game and roleplaying game industries. He has written gaming supplements for Deadlands and All Flesh Must Be Eaten, reads several dozen comics a month, and saves the world on a regular basis. Jack has kindly agreed to answer questions from Slashdot readers about game design, massive games, and what it's like to be a superhero, so go ahead and let em' fly. One question per post, please, but as many questions as you'd like. We'll forward the best on to Jack to answer and post his responses when we've got them.

Mark Shuttleworth isn't one to rest on his laurels. Founder of Thawte Consulting, Shuttleworth has used the wealth generated by Thawte's 1995 sale to Verisign to start a venture capital firm, to further South African science education (and education in general) with his eponymous foundation, to push for the acceptance of open source software in South Africa, and to become the first citizen of an African country to visit space with his 2002 flight to the International Space Station aboard the Russian Soyuz shuttle -- basically, to live life as a Neal Stephenson hero might. His latest project is Ubuntu Linux, a Debian-based distribution designed for ease of use, extensive language support, and thorough cooperation with the larger Debian organization. Mark's agreed to answer questions from Slashdot readers about these projects -- Ubuntu seems to be chief on his mind -- so please add your questions below, one per post (but as many questions as you'd like). We'll forward 10-12 of the best to Mark for his answers, and post them verbatim as soon as they're ready.

He starts by clearing up my error in saying he was a Unix co-creator in the original Call For Questions. From there he goes on to answer your questions both completely and lucidly. A refreshing change from the politicians and executives we've talked to so much recently, no doubt about it.

Today we return to our Slashdot interview roots with a "Call for questions" for Rob "Commander" Pike, who has been involved in the development of many modern programming concepts, GUI advances, character sets, and operating systems. We'll email 10 - 12 of the highest-moderated questions to Rob and post his answers as soon as he gets them back to us.

This is a strange post in that it has 50 comments attached to it already. These are 50 questions for Bush and Kerry selected by non-Slashdot moderators, as explained in our original call for help with the New Voters Project Presidential Youth Debate. At this point, where you come in is not only with extra-insightful moderation of these 50 questions, but with your "many eyes" trying to spot questions these two candidates have answered elsewhere so that the final questions presented to them are not repeats. The first 40 questions are from potential voters aged 18 - 35. The last 10 are from future voters 13 - 17. And that's enough explanation. From here we might as well jump right into the questions...

We're teaming up with the New Voters Project Presidential Youth Debate to ask the two major party candidates "the 12 previously unasked questions that most concern young Americans." This is different from the usual Slashdot interview because we're asking you to submit questions through the New Voters Project site instead of as comments attached to this post. Next week you'll have a chance to help select questions for the candidates from among the top 50 asked by everyone -- not just Slashdot readers -- by first winnowing those down to 20 through the Slashdot moderation system, then by voting on the "final 12" displayed on the New Voters Project site. On October 12 we'll post the answers, and on October 19 we'll post candidate-supplied rebuttals.

Today you have the opportunity to ask questions of the Green Party's candidate for President of the United States, David Cobb. Standard interview rules apply: we'll select a dozen or so of the best questions and Mr. Cobb will give us his answers next week.

Last monday, you were given the chance to Ask Questions of the Libertarian Party's US Presidential nominee, Michael Badnarik. Today we present to you 15 of the most highly rated comments, and the answers from the man himself. Thanks to Mr. Badnarik for taking the time to talk to us. His answers are yours with just a click of the mouse below...

The 10 questions we sent Real Networks CEO Rob Glaser were selected from 37 that were moderated +5 about 24 hours after we posted the "call for questions" last week. As promised, Glaser answered them himself rather than through PR people, but since part of a CEO's job is to be his company's number one booster it's not surprising that his answers have a high PR component to them; yours would too if you were in his position.

RealNetworks has always been more Linux-friendly than other streaming media purveyors, and is now moving closer to the open source camp with its Helix Community effort. More recently, Real has made a big media splash by selling downloadable tunes in an iPod-compatible format. Does any of this matter, considering that world + dog seems to be jumping on the downloadable multimedia bandwagon? Can Real once again become "the" streaming media leader? Will Real's 49 cent "limited time only" song download price force other music download vendors to cut their prices? We have no idea, but hopefully Rob Glaser does. He's promised to answer your questions personally (rather than have PR people speak for him). So ask whatever you like. We'll forward 10 of the highest-moderated questions to him by email and post his answers soon after he gets them back to us.

The idea of a Slashdot interview with Sam Greenblatt, Senior Vice President and Chief Architect of CA's Linux Technology Group, grew out of the company's decision not only to release its Ingres r3 database under an open source license but also their offer of up to $1 million to developers who write migration tools for it. Today we present Greenblatt's answers.

Several large companies have recently released previously proprietary software into the open source wilds. The splashiest announcement along these lines was from CA, who opened their Ingres r3database -- and offered up to $1 million in incentives for development of Ingres migration tools. For those of you who want to earn a piece of that money, and for all of us who have questions about how and why CA is cozying up to open source developers, the person with the answers is Sam Greenblatt, Senior Vice President and Chief Architect of CA's Linux Technology Group. So ask, already. We'll send 10 of the highest-moderated questions to Sam by email, and post his answers as soon as we get them back.

Back in 2001 we did a "double" Slashdot Interview with Michael Hart of Project Gutenberg and Jimmy Wales of the then-brand-new Nupedia, which has since become the amazingly useful Wikipedia. This is a perfect time to catch up with Jimbo (as friends call him), and learn not only how he managed to make Wikipedia work and grow so well, but what we can do to help -- and what future plans he has for this outstanding Web resource. (10 of your highest-moderated questions will be sent to Jimbo by email. We'll post his answers as soon as we get them back.)

This almost turned into a "State of the Wine Project" discussion, but that's where your highest-moderated questions led, and Jeremy responded with his usual wit, wisdom, and candor.

Alaa and his friends at Linux-Egypt put a lot of thought into answering your questions. Alaa wrote, "we felt there was much misinformation or lack of information about egypt while reading the comments so I kinda used each question to inject some extra info," which makes this Q&A worth reading for insight into Egyptian society even if you have no particular interest in Linux. Thanks, Alaa and Linux-Egypt.

There have been recent reports about programs from Israel, Canada, and The Philippines that let you run Windows software in Linux. Are they really new? Can they succeed? Is this whole effort worth the time and trouble going into it? CodeWeavers CEO and Wine maven Jeremy White ought to know, since he's been working to bring Windows software to Linux users for many years -- with quite a bit of success. We'll forward 10 - 12 of the highest moderated questions posted here to Jeremy, and run his answers as soon as we get them back.

The Linux-Egypt group recently held an amazingly successful installfest. This event was a milestone both for Linux installfests in general (was it the largest one ever held?) and for Linux in the Arabic world. Alaa Abd El Fatah, one of the organizers, has offered to answer your questions with help from other Linux-Egypt members. We'll post their answers to 10 or 12 of the highest-moderated questions as soon as we get them back.

Joanne Pransky's tongue is firmly in her cheek a fair amount of the time as she answers your questions, but much of what she says is thought-provoking, especially in light of speculations like Marshall Brain's Robotic Nation essays about the inevitable spread of robotic devices in our society.

No, not Dr. Susan Calvin. She's a fictional character who appears in a number of Isaac Asimov's works. Dr. Joanne Pransky is real, although she happily admits that she's modeled her career on the fictional Dr. Calvin. There is plenty of show biz razzle-dazzle (and humor) in Dr. Pransky's shtick -- she's been a judge on BattleBots and an engaging guest on many talk shows -- but there are hard academic underpinnings to it all, and she is as qualified as any living human being to answer your questions (one per post, please) about robot behavior and human-robot relationships. We'll send her 10 - 12 of the highest-moderated questions and have her answers back to you in about a week. (No hard-tech question, please. Those would go to a robotic internist or robotic orthopedist.)
