Now that Linux kernel 2.5 is under development by Linus and others, the all-important job of maintaining and updating the "old" kernel series (the one that people rely on in day-to-day use) has fallen to 2.4 maintainer Marcelo. You asked Marcelo about everything from the influence of politics (age and otherwise) to his working enviroment and approach to maintainership; his answers are below.

Dr. Edward Felten is in a funny position -- or perhaps not so funny. He's the Princeton researcher who took up the challenge posed by the music industry to find flaws in the SMDI watermarking scheme, but didn't enter into the 'no-telling' bargain (here's the click-through agreement [pdf]) which would have made him eligible for a reward, so wasn't bound by non-disclosure terms. When a scheduled academic presentation on the weaknesses [pdf] that he and his colleages found in SDMI became the object of lawsuit threats from the RIAA, and caused him to cancel the planned presentation, Felten decided to turn the tables, and in cooperation with the EFF, sue them instead, for interfering with his scholarly research. Though he did eventually get to present his research, the legal action is still going. Dr. Felten is at a hearing today in Trenton, NJ, but he's agreed to answer questions from Slashdot readers. Please confine your questions carefully (one per post), and we'll pass the highest-moderated ones on for his answers.

So the night after the live action Tick debuted on Fox, we rounded up 10 questions and sent them off to Ben Edlund, the Tick's original creator. Here are his answers. And you can download your official Tick poster (pdf format) here.

Linus keeps hinting (declaring, even) that he's nearly ready to work full-time on the 2.5 development branch of his kernel, and hand the 2.4 kernel off to Marcelo Tosatti. Marcelo's graciously agreeed to answer questions (you might want to read some of his mailing list contributions first), so here's your chance to ask him what he'll do in the famous footsteps of Linus and Alan Cox, and how he got there. Please only put one question per post; we'll pass along the top-rated comments to Marcelo for his answers, and hear back from him shortly.

Kent M. Pitman has already given you his first 11 answers to the questions you asked him about Lisp, Scheme, the creation of programming standards, and much more -- below are his answers to another eight (starting with answer #12). Thanks again, Kent.

Bruce Campbell has a new book out (If Chins Could Kill) and I thought it would be fun for Slashdot to interview him in our charming, enigmatic way. Bruce should be familiar to you though such films as the Evil Dead (include Army of Darkness) and ,well, anything Sam Raimi has ever done. The book is a lot of fun. As usual, moderate up your favorite questions, and I'll pass on the highest scoring ones to Bruce so that he can reply to 8 or so. Bruce has a website for you to check it. It's got a FAQ and bio for you to examine.

The non-cartoon Tick debuted on Fox last night, so this is an ideal time to have Tick creator Ben Edlund as a Slashdot interview guest. Before you start typing, you may want to read this May 2000 interview with Ben to keep from duplicating questions and to see what kind of person he is. Then ask away. As usual, we'll send 10 of the highest-moderated questions to Ben, and publish his answers as soon as we get them back.

A few weeks ago, you asked Kent M. Pitman about Lisp, Scheme, standards, and other things -- He's answered your questions below, at length. At such length, in fact, that only the first eleven of his answers are shown below -- expect more shortly! Thanks, Kent.

Daniel Weitzner is Chairperson of the World Wide Web Consortium's Patent Policy Working Group,the body that is deciding if it's okay to charge "Reasonable and Non-Discriminatory" (RAND) license fees for use of W3C-endorsed standards that are covered by patents or other trade restrictions. We sent him the questions you asked back on October 8. Here, at long last, are his answers.

John Young of Cryptome, though trained as an architect, has garnered recognition in another field entirely. Since 1996, he's been publishing timely, trenchant news online as the mind behind crypto jya.com and Cryptome. ("Our goal is to be the most disreputable publisher on the Net, just after the world's governments and other highly reputable bullshitters." ) This has put him on the forefront of various online liberty issues, from the MPAA's DeCSS crackdown on DeCSS (he fought the lawyers -- and won), to Carnivore, to Dmitry Sklyarov's continuing imprisonment, and now the several fronts along which electronic communications are threatened by current and upcoming legislation. He recently posted this to the front page: "Cryptome and a host of other crypto resources are likely to be shutdown if the war panic continues. What methods could be used to assure continued access to crypto for homeland and self-defense by citizens of all nations against communication transgressors?" Now's your chance to ask him about the fight for online freedom. Please pose just one question per post; we'll send 10-15 of the highest moderated ones on to John for his answers.

Jeremy Andrews writes: "Kerneltrap interviews Keith Owens this week, an experienced kernel hacker who has long contributed to the Linux kernel. His contributions include updating ksymoops and modutils, both of which he maintains. He also works on kbuild 2.5. Earlier, he built the original Integrated Kernel Debugging patch. He's also working on kdb and XFS. Check out the interview." Lots of good information in here about things to expect in 2.5.

Jeremy Andrews writes: "Kerneltrap has posted the latest in-depth kernel hacker interview with Russell King, who originally ported Linux to ARM and continues to oversee ARM Linux development. Russell talks about ARM, the 2.4 kernel, the upcoming 2.5 kernel and much more..."

Wil Wheaton [IMDB] is our latest interview victim. Best known here as Wesley Crusher on TNG, Wil has a history doing movies both good (Stand by Me) and, uh, otherwise (see his FAQ). His movie "The Good Things" just won the grand prize at the 27th Festival of American Cinema at Deuville. His currrent project is "Jane White Is Sick & Twisted". Post your questions for him here, one per post, and we'll forward a few of the highest rated ones to Wil.

Kent M. Pitman has been programming in Scheme and Lisp, and contributing to the design of those languages, for a long time -- 24 years. He was a technical contributor and an international representative for the ANSI subcommittee that standardized Common Lisp, and in that capacity directed the design of Lisp's error system. Scheme may be better known as a teaching language, but both Scheme and Lisp have applications (as any Emacs user knows) that go far beyond this. Now's your chance to ask him about the pros and cons of those two languages, circa 2001 A.D. Kent also has an interesting, ambivalent take on Free software that's worth noting in an atmosphere where complex issues are often oversimplified and radicalized. Since he's someone who's helped develop standards, this is perhaps a timely issue on which to probe his opinion. It's also a good time to get acquainted with things he's written, which might interest you just as much as his programming. (Soap opera parodies, anyone?) So suggest questions for Kent below (please, one per post) -- we'll pass along the highest-rated ones for him to answer, and Kent will get back soon with his answers.

We put up the original call for questions on September 5. Jamie's travel schedule (mentioned in one of his answers) is so hectic that it is amazing he found time to answer these questons at all. But answer he did, in detail. It's going to be interesting to see how Jamie's take on tech-oriented lobbying compares with that of "commercial" lobbyist Morgan Reed, whose interview responses we hope to see in the very near future.

Danny Weitzner is Director of the World Wide Web Consortium's Technology and Society activities, which means he's in charge of handling reactions to a W3C proposal that would allow "Reasonable and Non-Discriminatory" (hence "RAND") license fees to be charged for use of W3C-endorsed standards that are covered by patents or other trade restrictions. Many prominent Free Software and Open Source people are firmly against RAND; RMS has even emailed me personally several times, asking me to post a link to this anti-RAND story (in which he is quoted). Slashdot has mentioned this controversy before, because we, too, feel it's important.. But Danny is the person at W3C who is dealing directly with all of this, so he's the person we should question. So ask away, one question per post as usual, and we'll post Danny's answers to 10 of the highest-moderated questions as soon as he gets them back to us.

Morgan Reed is a lobbyist in Washington, D.C. with the law firm of Venable, Baetjer, Howard & Civiletti. He has represented a wide range of clients, from the International Pizza Hut Franchise Holders Association (really) to the Telecommunications Industry Association and the National Association of Software and Service Companies (NASSCOM). That means he's paid to personally persuade (not to mention cajole and badger) lawmakers with real shoe-leather tactics, on issues that few lawmakers have the time to personally spend years learning about. He's also a Slashdot reader and Linux hacker, with work on the Linux Router Project (LEAF/ LRP). Morgan has volunteered to expand your knowledge about the intersection of technology and politics. Ask Morgan (one question per post, please) about how clueful politicians are when it comes to technology, what tactics are likely to impress your representatives to make intelligent tech-related decisions, and what you can do to steer the course of legislation which could affect your freedoms. We'll pass your questions on to Morgan, who will get back with answers shortly.

The little No Regrets about PGP piece from Philip Zimmermann and the associated interview "call for questions" we ran on Sept. 24 seems to have stirred up quite a ruckus. Apparently online crypto has become such a hot button issue that it is impossible to hold a rational conversation on the topic right now. Because of this, instead of answering the interview questions, Philip sent us a brief statement. We'll try to interview him (and other crypto experts) later, after passions die down a bit.

Philip R. Zimmermann, creator of PGP, was quoted in a recent Washington Post article as saying he has been "overwhelmed with feelings of guilt" about the use of PGP by suspected terrorists. Zimmermann says the story was not entirely accurate, and has written a response to it (below) that he hopes will clear things up. He has also consented to a Slashdot interview, so please post any questions you have for him. As usual, we'll send 10 of the highest-moderated ones to Zimmermann by email, and post his replies verbatim as soon as we get them back.

A little while ago you asked Forth (and now colorForth) originator Chuck Moore about his languages, the multi-core chips he's been designing, and the future of computer languages -- now he's gotten back with answers well worth reading, from how to allocate computing resources on chips and in programs, to what sort of (color) vision it takes to program effectively. Thanks, Chuck!
