Chuck Moore is, among other things, a chip designer. His latest design, the 25x, is based on a 5x5 array of X18 microprocessor cores, and could provide 60,000 MIPS with a production cost of about one dollar. And Moore has the chops to back that up: he's been designing tiny, efficient processors for many years. He's also the inventor of the programming language Forth, which has evolved from a miniscule but radically fast language "difficult for a human to read" (according to The Secret Guide) to the even more radical colorForth. How radical? Try "includes own operating system; has own 27-key Dvorak keyboard layout; meaningful color syntax." How's that for starters? Ask below your questions for Chuck about processors and programming (ask all you'd like, but one per post, please) We'll pass the best ones on to him, answers soon to follow.

Last week you asked Sam Lantinga , developer of the Simple DirectMedia Layer (SDL) about SDL and other issues related to gaming. He's responded with answers about the SL port to Sony Playstation, game audio, DirectX, his new job at Blizzard, and more. He even drops some hints about some interesting gaming developments to watch out for.

Last week you asked Bradley Kuhn, VP of the Free Software Foundation (FSF) questions about working with RMS, his views on software freedom, and much more. He's answered at length below, on everything from becoming a saint to the "web app loophole," perl, and the next iteration of the GPL.

Sam Lantinga is the author and project lead of the Simple DirectMedia Layer (SDL), which was recently ported amid general acclaim to the Sony PS2. People have been curious about SDL for a long time (it's been around for a while, and used in quite a few games). He's not just a library programmer though; he also designs games (in this case, working with Lauren MacDonell) and thinks hard and lucidly about the intricacies of information display within them. Here's your chance to ask Sam directly what's on your mind about SDL, game design and more. Note -- many questions are answered within the links already given, so hit those first. One question per post, please (but as many posts as you'd like) -- we'll forward the highest-rated questions on to Sam, and post his answers soon after.

There's more to the Free Software Foundation than Richard M. Stallman, you know. Like bkuhn, AKA Bradley M. Kuhn, who has been a full-time employee of the organization since February '01 and has taken over some of the duties that were previously RMS's exclusive province. Got a question for bkuhn about the FSF -- or anything else? Post it below. We'll select 10 of the highest-moderated questions, forward them to bkuhn, and post his replies as soon as we get them back.

Last week, you asked Shawn Gordon questions about his venture TheKompany, an outfit which has been (fairly) quietly working on a small flotilla of software for GNU/Linux systems, and some cross-platform applications as well. His responses are below; you might be surprised at a few of them. (And some lucky Debian hacker might even pick up a job.)

We sent 10 of your questions to IBM Linux exec Scott Handy a while back. Here are the answers. As is common with corporate types these days, a PR person had a hand in what was said, so please take that into account as you read on. But I don't think anything much was changed (I can usually tell) in this case, though.

These are Robert's answers to questions about GnuCash you posted on June 18th. He says, "Some of the answers to the questions here were the result of discussions with the other people at LDG, where others were more qualified to speak on various topics, so the readers are really getting the benefit of our collected wisdom (well, we hope it's wisdom :) )"

His name is Scott Handy, and his full title is "Director, Linux Solutions Marketing, IBM Software Group." You want to know how to market Linux? Or how IBM's going about it? Scott ought to know. One question per post, please. We'll send 10 of the highest-moderated ones off tomorrow, and expect Scott's answers back in about a week.

Okay, here's a nice "behind the curtains" peek into the way tech industry analysts (who are not the same as stock analysts) get and interpret their data, courtesy of IDC analyst Dan Kusnetzky, in the form of answers to the insightful questions you asked him last week.

GnuCash is probably the best-known Linux accounting program for home and small business users. GnuCash development is now sponsored by The Linux Developers Group, Inc., a company formed this May by the core GnuCash developers, including Robert Merkel, who originally got involved with GnuCash because, he says, "I was sick of my father nagging me about the dud accounting program he used." Please feel free to ask Robert about GnuCash, guile, shared libraries or almost anything else, even cricket. (He's Australian and a major cricket fan.) We'll send Robert 10 of the highest-moderated questions, and post his answers as soon as we get them back.

How many people run Linux as a desktop OS? How many servers run Linux? Is the Linux server market share 8.6 percent or 24 percent or somewhere in between? Dan Kusnetzky is a heavily quoted analyst at IDC who wrestles with questions like these for a living. This is your chance to find out how analysts come up with all those numbers -- and why analysts seem to disagree with each other so often. One question per post, please. We'll send 10 of the highest-moderated ones to Dan, and post his answers as soon as we get them back.

Quite a while back we asked Dan Ravicher, a young attorney who is personally interested in Open Source and Free Software licensing issues, a bunch of questions on the subject. We waited and waited for his answers, and the wait turned out to be worthwhile because Dan ended up writing what amounts to a legal FAQ for Open Source and Free Software developers. This is important reading for anyone involved in any way with Open Source or Free Software development.

Many people have scorned and laughed at Thomas A. Edison, Albert Einstein, and Nikola Tesla, it says on Alex Chiu's famous Web site, where Alex explains the mysteries of the universe, tells us how we can make the future better, and offers immortality (for a very reasonable price) through his patented immortality devices. Alex has enough of a following among Slashdot readers (and editors) that when I posted a two-line comment saying I'd ask him to do a Slashdot interview if I got 10 requests by email, I got lots more than that. So here we go! One question per post, please. We'll forward 10 of the highest-moderated questions to Alex on Monday, and post his answers as soon as we get them back.

I first ran into Daniel B. Ravicher on the Open Source Initiative's license-discuss email list. He's a rarity: a young lawyer actively interested in and sympathetic to Open Source licensing. In fact, he wrote a detailed article on this topic for the Virginia Journal of Law and Technology last year while he was still in law school. Dan is now an associate at Brobeck, Phleger & Harrison LLP, a firm that handles, among other things, business law and intellectual property matters. Who better to ask about Open Source under the law? (The usual attorney disclaimer applies, of course -- that Dan can only answer general law questions, and if you want specific legal advice you must directly engage an attorney yourself.) One question per post, please. Tomorrow we'll forward 10 of the highest moderated ones to Dan by email, and put up his answers as soon as we get them back.

Here you go - answers to your questions for Guido van Rossum about Python, its future, licensing hassles with the Free Software Foundation, and other neat stuff. Thanks, Guido!

This week's interview is with Guido van Rossum, a man who, as they say, needs no introduction. (Not around here, at least.) To learn a bit more about him, check his personal page. You might want to ask him about Python 2.1, which was released today. One question per person, please. We'll send 10 of the highest-moderated ones to Guido about 24 hours after this post went up, and will run his answers as soon as he gets them back to us.

Bob Young prefaces his answers to your questions by saying, "You may notice I've ducked some of the answers below - there is a reason for this. My role at Red Hat these days is as Chairman of the board. Matthew Szulik is Red Hat's CEO and will be a better person to answer some of the specific issues that these questions raise....

Yes, that Bob Young. The one who helped endow online information resource ibiblio.org, but is better known for his role as co-founder and Chairman of Red Hat. Ask him anything you want, but please hold it down to one question per post. We'll send 10 of the highest-moderated inquiries to Bob (who is in England this week), and he'll send back his answers just as soon as he can.

Doug Miller (no relation) is an amazingly affable and unflappable man. This interview came about because I asked Doug face-to-face if he'd do it when we met after a panel discussion he was part of in Washington DC a few weeks ago. He said "sure" without even a second's hesitation, let alone checking with PR people. His answers to the 10 selected questions we sent him are 100% straight-up. You may not like everything he says (devout Free Software people probably won't like any of it), but Doug Miller deserves your respect (and courtesy) for telling it like it is -- at least from Microsoft's point of view -- without a hint of weaseling.
