Ars Technica reports on a study suggesting that "Striking at a myth with facts may only shore it up." Applehu Akbar writes: Researchers at the University of Edinburgh studied public attitudes toward vaccination in a group whose opinions on the subject were polled before and after being shown three different kinds of explanatory material that used settled scientific facts about vaccines to explain the pro-vaccination side of the debate. Not only was the anti-vax cohort not convinced by any of the three campaigns, but their attitudes hardened when another poll was taken a week later.

What seems to have happened was that the pro-vax campaign was taken by anti-vaxers as just another attempt to lie to them, and as reinforcement for their already made-up minds on the subject. A previous study at Dartmouth College in 2014 used similar methodology and except for the 'hardening' effect elicited similar results. What's really scary about this is that while the Dartmouth subjects were taken from a large general population, the Edinburgh subjects were college students.
"The researchers speculate that the mere repetition of a myth during the process of debunking may be enough to entrench the myth in a believer's mind," writes Ars Technica, with one of the study's authors attributing this to the "illusory truth" effect.

"People tend to mistake repetition for truth."

chicksdaddy writes from a report via The Security Ledger: Hospitals are pretty hygienic places -- except when it comes to passwords, it seems. That's the conclusion of a recent study by researchers at Dartmouth College, the University of Pennsylvania and USC, which found that efforts to circumvent password protections are "endemic" in healthcare environments and mostly go unnoticed by hospital IT staff. The report describes what can only be described as wholesale abandonment of security best practices at hospitals and other clinical environments -- with the bad behavior being driven by necessity rather than malice. "In hospital after hospital and clinic after clinic, we find users write down passwords everywhere," the report reads. "Sticky notes form sticky stalagmites on medical devices and in medication preparation rooms. We've observed entire hospital units share a password to a medical device, where the password is taped onto the device. We found emergency room supply rooms with locked doors where the lock code was written on the door -- no one wanted to prevent a clinician from obtaining emergency supplies because they didn't remember the code." Competing priorities of clinical staff and information technology staff bear much of the blame. Specifically: IT staff and management are often focused on regulatory compliance and securing healthcare environments. They are excoriated for lapses in security that result in the theft or loss of data. Clinical staff, on the other hand, are focused on patient care and ensuring good health outcomes, said Ross Koppel, one of the authors of the report, who told The Security Ledger. Those two competing goals often clash. "IT want to be good guys. They're not out to make life miserable for the clinical staff, but they often do," he said.

mask.of.sanity writes Forensics and industry experts have cast doubt on an alleged National Security Agency capability to locate whistle blowers appearing in televised interviews based on how the captured background hum of electrical devices affects energy grids. Divining information from electrified wires is a known technique: Network Frequency Analysis (ENF) is used to prove video and audio streams have not been tampered with, but experts weren't sure if the technology could be used to locate individuals.

Hugh Pickens DOT Com writes "Thomas Kienzle reports for the Associated Press on a study which found public health campaigns touting vaccines' effectiveness and debunking the links between autism and other health risks might actually be backfiring, and convincing parents to skip the shots for their kids. 'Corrections of misperceptions about controversial issues like vaccines may be counterproductive in some populations,' says Dr. Brendan Nyhan. 'The best response to false beliefs is not necessarily providing correct information.' In the study, researchers focused on the now-debunked idea that the vaccine for measles, mumps and rubella (or MMR) caused autism. Surveying 1,759 parents, researchers found that while they were able to teach parents that the vaccine and autism were not linked, parents who were surveyed who had initial reservations about vaccines said they were actually less likely to vaccinate their children after hearing the researchers messages. Researchers looked at four methods designed to counter the myth (PDF) that the MMR vaccine can cause autism. They gave people either information from health authorities about the lack of evidence for a connection, information about the danger of the three diseases the MMR vaccine protects against, pictures of children who had one of those three diseases, or a story about an infant who almost died from measles.

At the study's start, the group of parents who were most opposed to vaccination said that on average, the chance they would vaccinate a future child against MMR was 70 percent. After these parents had been given information that the MMR vaccine does not cause autism, they said, on average, the chance they would vaccinate a future child was only 45 percent — even though they also said they were now less likely to believe the vaccine could cause autism. Vaccination rates are currently high, so it's important that any strategies should focus on retaining these numbers and not raise more concerns, tipping parents who are willing to vaccinate away from doing so. 'We shouldn't put too much weight on the idea that there's some magic message out there that will change people's minds.'"

Freddybear writes "Digital forensics experts at Dartmouth have developed software that can analyze digital photos to rate how drastically they have been altered by digital editing techniques. 'The Dartmouth research, said Seth Matlins, a former talent agent and marketing executive, could be "hugely important" as a tool for objectively measuring the degree to which photos have been altered.'"

Mike Sauter sends in a piece from Wired profiling research by Andrea Lunsford, a professor of writing and rhetoric at Stanford, from which she concludes that we don't need to worry about computers and the Internet causing a decline in general literacy. "[Lunsford] has organized a mammoth project called the Stanford Study of Writing to scrutinize college students' prose. From 2001 to 2006, she collected 14,672 student writing samples — everything from in-class assignments, formal essays, and journal entries to emails, blog posts, and chat sessions. Her conclusions are stirring. 'I think we're in the midst of a literacy revolution the likes of which we haven't seen since Greek civilization,' she says. For Lunsford, technology isn't killing our ability to write. It's reviving it — and pushing our literacy in bold new directions."

An anonymous reader writes "Researchers at Dartmouth College have developed new software that uses the microphone on the iPhone to track and interpret a user's everyday activities using sound. The software, called SoundSense, picks up sounds and tries to classify them into certain categories. SoundSense can recognize completely unfamiliar sounds and runs entirely on the phone. It automatically classifies sounds as 'voice,' 'music,' or 'ambient noise.' If a sound is repeated often enough or for long enough, SoundSense gives it a high 'sound rank' and asks the user to confirm that it is a significant sound and offers the option to label the sound. In testing, the SoundSense software was able to correctly determine when the user was in a particular coffee shop, walking outside, brushing her teeth, cycling, and driving in the car. It also picked up the noise of an ATM and a fan in a particular room. The results [PDF] of the experiments were recently presented at the MobiSys 2009 conference."

Anonymous writes "Engineering students at Duke University have taken advantage of the accelerometers in emerging cell phones to create an application that permits users to write short notes in the air with their phone, and have that note automatically sent to an e-mail address. The 'PhonePoint Pen' can be held just like a pen, and words can be written on an imaginary whiteboard. With this application a user could take a picture with a phone camera, and annotating it immediately with a short caption. Duke Computer Engineering Professor Romit Roy Choudhury said that his research group is envisioning mobile phones as just not a communication device, but a much broader platform for social sensing and human-computer interaction. Such interactivity has also emerged in the work of other research groups, such as MIT's Sixth Sense project, Dartmouth's MetroSense project, and Microsoft Research's NeriCell project, to name a few."

Bob Hearn writes "I was in attendance at the US Go Congress match yesterday where history was made: the go program MoGo, running on an 800-core supercomputer, beat 8-dan professional go player Myungwan Kim in a 9-stone handicap game. Most in the audience were shocked at the computer's performance; it was naturally assumed that the computer would be slaughtered, as usual. Go is often seen as the last bastion of human superiority over computers in the domain of board games. But if Moore's law continues to hold up, today's result suggests that the days of human superiority may be numbered." Read below for more details in Bob's account of the match.
Computers are still a long way from beating the best human players in an even game; nevertheless, today's performance represents a huge stride forward. In the last such high-profile matchup, in 1997, Janice Kim (then 1-dan professional) beat then-champion program Handtalk with a 25-stone handicap. In fact, most of the improvement in the level of computer-go play has happened in just the past few years. Today's top programs, including MoGo, use a Monte Carlo approach: they simulate thousands of random continuations per second from the current position to the end of the game, accumulating statistics in a tree on which moves lead to wins most often. One of the strengths of this approach is that it is highly amenable to parallelization. Thus, today's 800-core incarnation of MoGo is by far the strongest go computer that has yet existed. After the game Myungwan Kim estimated the strength of MoGo as 'two or maybe three dan,' corresponding to a reasonably strong amateur player. (Professional dan ranks are at a much higher level than amateur dan ranks.)

Hugh Pickens writes "Researchers at Dartmouth University have recently discovered that infrequent anonymous contributors, so called "Good Samaritans," are as reliable as registered users who update constantly and have a reputation to maintain. A graph from page 31 of the group's original paper (pdf file) shows that the quality of contributions of anonymous users goes down as the number of edits increases while quality goes up with the number of edits for registered users."

An anonymous reader writes "Two Dartmouth researchers claim that they are one step closer to discovering at what age human maturity sets in. From the article: 'For the study, Baird and graduate student Craig Bennett looked at the brains of nineteen 18-year-old Dartmouth students who had moved more than 100 miles to attend college. A control group of 17 older students, ranging in age from 25 to 35, were also studied for comparison. The results indicate that significant changes took place in the brains of these individuals. The changes were localized to regions of the brain known to integrate emotion and cognition. Specifically, these are areas that take information from our current body state and apply it for use in navigating the world.'"

TheSync writes "Dartmouth researchers have developed the world's smallest untethered, controllable microrobot. The microrobot is much smaller and less massive than previous controllable microrobots. It measures only 60 by 250 micrometers. It receives power and control signals from the grid of electrodes it walks on, and moves by bending its body like a caterpillar. Not quite nanomachines, but we are getting closer!"

jackelfish writes "Reminiscent of handwriting analysis software used in the television series CSI, computers are now being used to evaluate the authenticity of works of art without an expert ever setting eyes on it. The technique identifies the artist by analyzing their characteristic brush or pen strokes from high resolution scans of previously authenticated works. Much like a fingerprint, these characteristics can then be compared to a work in question. The method, to be published in an upcoming issue of the Proceedings of the National Academy of Sciences promises to reduce the subjectivity of art assessments made by human experts."

nusratt writes "Some years ago, an issue of 'Whole Earth' had a convincing cover-photo of a flying saucer cruising low over downtown San Francisco in broad daylight. The accompanying feature article proclaimed that photographs can no longer be trusted as evidence of anything, because of the ease of doctoring images digitally and undetectably. Now, Dartmouth Professor Hany Farid and graduate student Alin Popescu 'have developed a mathematical technique to tell the difference between a "real" image and one that's been fiddled with.' Farid says, 'as more authentication tools are developed it will become increasingly more difficult to create convincing digital forgeries'." There's also an NYT story.

Now I know coders aren't rocket scientists, but less advanced than project managers? Ouch."

The Mainframe asks: "My town (Hanover, NH, home of Dartmouth College, the Dartmouth Medical School, and Dartmouth-Hitchcock Hospital, non-college population approx. 9K people, double that with the college) is conducting a feasibility study on building a town network. They'd like to deliver fiber to every home within town limits. This fiber will carry (certainly) the internet and (probably) cable-like television programming access. They're estimating that it will cost $40 per month per household. I just filled out and returned my survey (one sent to every Hanover household) in which they asked a number of questions like: 'What would your primary use of this service be?' and 'Would you be willing to pay $40 a month for this service?'. What reasons, other than the obvious benefit of having fiber to one's house, can you think of for making this kind of commitment to the infrastructure?

"I would imagine that there will be an enormous secondary benefit because we will become an attractive town to technically inclined people and businesses. At the same time, Is this a good idea? I, personally, think it would be wonderful, but (as an IT major) the technical challenges of laying fiber and maintaining a network to serve 9000+ citizens are mind boggling. Policy decisions, network abuse, outages, spam, filtering (god forbid), all nightmares that will require a dedicated, 24/7 network maintenance team. Any network engineers out there have any juicy morsels from their work on large networks?

I know the town manager, so I'd like to feed this discussion to her, after moderation has taken its toll (probably at a level of +3), so she can see what the technical community thinks."

An anonymous reader submitted a fairly thin little story about a researcher who is Battling Steganography.

This week's interview guest with Eric S. Raymond. We got a *lot* of good questions, forwarded the moderators' favorites to Eric, and he not only answered the ones we sent him but - extra cool - picked some more out of the crowd and answered them, too. Read the complete session (below) and if you have something you want to add, go ahead. If Eric has time, he'll jump in and respond, because, well, he's just that kind of guy. ;) Note: questions marked with * are the ones Eric added to the moderators' selections.

chromatic asks:
Astute readers know why you've reluctantly taken a position as a Linux evangelist, open source sociologist, and prime target. Taking the opposite approach, is there anything which would convince you to step down, that your posts were no longer necessary?

This is not meant to be inflammatory ... it's just a roundabout way of asking how far along your goals are, and what your plans will be if you ever meet them.

ESR answers:
Three things could cause me to step down:

• One: someone emerging to do the public-advocate job clearly better than I do.
• Two: Linux's market share going over 50%. (Cool down, BSD guys -- I'd be equally pleased to see some other open-source Unix win, it just doesn't seen very likely at this point).
• Three: a collapse in Microsoft's stock price. That would mean the end of effective FUD and countermarketing against open source.

ivo asks:
A while ago, we read from you that being the Open Source advocate you are was wearing you down and influencing your life very badly. Did you cut down on advocating and did it help? In other words, did you get your life back?

ESR answers:
Not really. Something more remarkable happened instead; the community responded to my distress call by growing up a little. I got letters of apology from some of the worst flamers. Many people in the rest of the community started pressuring the pinheads who had been making my job harder to shut up or get constructive.

I have also cut down somewhat on my travel schedule, but not as much as I thought earlier this year I would have to. I'm also demanding (and getting) better travel conditions -- business class instead of the cheap seats in coach. It makes a difference, more of one than I would have thought.

Stephen Williams asks*:
I'm glad to see that, after a three-year break, the Jargon File has been updated over the past few months. Is version 5.0.0 in the works? Are there any plans to release an update to the print version, The New Hacker's Dictionary, any time soon?

ESR answers:
I've discussed the possibility with people at O'Reilly. That might be my second-to-next book, after "The Cathedral and the Bazaar" and before "The Art Of Unix Programming" (which is about half-done now but could take me another nine months to finish). Whether I go with O'Reilly or the publisher of the previous editions (MIT Press) the fourth edition of TNHD seems likely to come out next year sometime.

Tom Christiansen asks:
I don't know how to ask this question without it sounding like stirring the pot, but what about the growing chasm between free software (giftware) and GNU software (the viral kind, not the nice LGPL kind)? This is a real issue for some people in some situations. Think about the many BSD resellers and vendors who have custom packaging in highly competitive fields, like video editing? Doesn't the friction hurt everyone? Apple has turned to BSD not Linux, and the GPL is cited as one reason why. This seems to be devisive. There are no end of flamewars on /. and elsewhere, and the heat diminishes the light. What kind of reconciliation is possible? Or is "take no prisoners" just the way it has to work?

ESR answers:
I don't see a chasm there, Tom. After all, we're all still writing and exchanging code. We're all using basically the same set of licenses. I don't think there are properly two different movements at all, outside the imaginations of a few rather fanatical partisans on both sides.

Here is the reality test: if you're running a project and someone sends you a patch, will you stop to enquire whether that person is a member of the correct faction before you apply it? I don't think so...

So despite the verbal fireworks and philosophical disputes, we're all hackers together. What unites us is more important than what divides us.

Tet asks:
You say you want to live in a world where software doesn't suck. I couldn't agree more. However, do you see closed source software on an open source OS as a step in the right direction, or just likely to be a more stable platform on which to run your potentially bug-ridden software?

ESR answers:
Step in the right direction, definitely. As more and more infrastructure goes open, and the remaimning closed-source applications increasingly use it for leverage, the overall quality of the applications will go up.

planet_hoth*:
Recent interest shown by large commercial tech companies (IBM, SGI, Sun) seems to signal a new chapter in the history of Linux. Do you see the participation of these companies strengthening the linux communitity? Destroying it? Or transforming it into something completely different?

ESR answers:
Look around you. What do you see, compared to a year ago?

Do you see fewer Linux hackers writing open source, or more? Do you see fewer hackers getting *paid* to write open source, or more? I think the answer is pretty clear.

Do you see our designs, or our licenses, or our coding practices being changed in any significant way by corporate participation? Again, I think the answer is pretty clear.

The truth is, they're not transforming us. We're transforming them.

asad asks*:
I know that you are on the board of directors at VA Linux, what does your job entail?

ESR answers:
My job at VA mostly involves sitting in a board meeting once a month asking searching questions about what the firm is doing and why. My role there (as Larry Augustin describes it) is to be the official corporate conscience. This mainly involves nipping bad ideas in the bud, before they flower into something that would piss off the hacker community. I have not had to do this often.

shawnhargreaves asks:
You've always been involved in hacker projects outside of just coding (eg. the Jargon File), but over the last year or so the spokesperson role seems to have grown into a fulltime job. How long is it since you last sat down to write a major piece of software? Do you expect to go back to fulltime development work anytime soon, and if so, what would you work on? How do you manage to cope with the withdrawal symptoms?

ESR answers:
An astute question ;-). I haven't sat down to write a major piece of software from scratch in months, but I am continuing to maintain fetchmail. I just took over the gif2png beta code with Greg Roelofs's consent; the 1.0.0 version might be out by the time you read this. Today I did some work on gnuplot, bringing the PNG driver up to date.

If I get to go full-time again soon, I want to go back to work on Trove, the distributed web-based code-archiving system I designed last year. I'd also like to work with Guido van Rossum on Python 1.6; there are some long-time wishlist features like rich comparisons and a full lambda facility that I care enough about to implement myself. I also have a strategy-gaming system I wrote back in the 1980s that I'd like to put a modern (Web-based) interface on. Finally, having contributed a bit of code to GNOME (the network-monitor applet) I'd like to balance things by doing something for KDE.

meersan asks:
This has probably been asked before, but I can't recall seeing the answer to it anywhere. What originally led you to write The Cathedral and the Bazaar? -- what I'm interested in is if there was some event or impetus that prompted you to write it down. Obviously you'd have no way of predicting the firestorm that followed, but it's always intriguing to know about the spark that started it all

ESR answers:
I wrote CatB as a way of coping with my astonishment in the face of the Linux phenomenon. What I observed was that the community around Linux had evolved a way to write software that (a) was tremendously effective, (b) violated the classic Brooks's Law rules, and (c) was completely unconscious! Nobody reflected on what they were doing; it was practice without theory. I wrote CatB as an attempt to help my tribe become more conscious about what it has been doing.

What conferences are you planning to attend this year? Do you have plans for organizing Geeks with Guns outings during them? If so, is there a mailing list or some other source of information about how to join?

ESR answers:
No comment on that first question. But, if you could see my face, I'm wearing a very evil grin....

See my speaking calendar for the conferences I plan to attend. As for GWG, there's no mailing list; would you like to host one? I rely on local organizers to find a range, and I don't have one for Atlanta Linux Showcase yet.

banky asks:
Linux, like all things in the computer world, will eventually become obsolete or maybe just too much work to keep "up to date". Linus (er, Dr. Torvalds) even said in his "Open Sources" essay that (paraphrasing) someone else could come along and write something better which will take Linux's place. How long do you think before someone will have an offering that will obsolete (or at least prove a competitor to) Linux and the BSD's?

ESR answers:
I doubt Linux will have a real technical competitor for a long time, because I think it will probably just absorb new architectural ideas, amoeba-like, as they evolve. Twenty years from now the core APIs may have grown and changed tremendously, but we'll still think of it as the `same' codebase and call it Linux :-).

scumdamn asks:
Is the friction between Gnome and KDE, BSD and GPL, Free Software and Open Source, and the other sources of flame war a bad thing or a good thing for the movement? Many people seem to feel that the competition is devisive, but isn't it the opposite? We're always preaching that competition is a good thing for the entire market, but then we complain when any of our pet projects are pitted head to head with another. The passion felt by the proponents of each philosophy seems to result in better, more quality work. Isn't this proof that competition is the Good Thing we've been saying it is all along?

ESR answers:
I think you answered your own question :-).

cemerson asks:
Which of the coders working on open source projects do you admire the most? A particular big name like Linus, or someone less well-known?

ESR answers:
Hmmm. I don't think there's anyone I can say I admire the most. There's a level of ability beyond which trying to make comparisons between people just gets silly, because each of the people that good has become a sort of perfect master of his own domain. Linus. RMS. Larry Wall. Guido van Rossum. James Gosling. Going further back, Ken Thompson or Dennis Ritchie. Anyway, I find these guys have gotten their fill of being admired, so I try to be friends with them instead.

K asks:
Why isn't there an entry for "free software" in the Jargon Dictionary? Was this a politically-motivated decision?

ESR answers:
Zounds! You know, until this moment, I didn't realize that entry was missing.

I don't think you want me to write it, though. I would find it hard to avoid using phrases like "rhetorical millstone around our necks" and "held us back for fifteen years". Care to submit one yourself?

Paul Crowley asks:
In Understand my job, please! you described Bruce Perens's proposal that we have a team of Linux advocates sharing the load as "glib". Could you say more about why you feel this way - isn't it more likely that a job where the load is shared would be more attractive?

ESR answers:
I think I answered that question in the same paragraph you quoted. What makes the job rough isn't the workload, it's the second-guessers and snipers from the sidelines -- among whom Bruce was, at the time, nearly the worst. Connect the dots yourself.

jflynn asks:
Starting an open source project from nothing but people with a common interest is difficult. It's been my experience that it is very easy to founder with a bazaar approach to architecture and design. The issues tend to get confused with religious wars about toolkits and license choice, and just a lot of differing opinions about how to best structure a program, no one of which may be *obviously* better.

Is it essential for individuals to first create a working model, incomplete and buggy it may be, before applying bazaar development? Or what would you suggest in terms of managing a bazaar approach to creating programs from a bare idea?

ESR answers:
I wouldn't. I think you're right; the successful projects have a core of individual vision around which the bazaar community nucleates.

elutfall asks*:
Since, as we all know, cheese is the most powerful substance in the universe, I was wondering what your favorite source of ultimate power is?

ESR answers:
That would have to be sex, because I'm allergic to cheese.

Christian Reiniger of the new Linux Game Development Project has written up a nice piece that you might want to read if you want to see more games on Linux, and how this new project will aid that. The way I see it, the apps are coming, and in many cases, already here. We just need the games. The following was written by Slashdot Reader Christian Reiniger The Linux Game Development Center Rationale

Linux is gaining much attention these days. People who were anti-Linux for a long time suddenly discover that it has changed much the past few years, ultraconservative magazines feature positive stories about Linux at prominent places and The Big Ones in the computer business are almost crowding to support the former "hacker OS".

Good press is always welcome - but can Linux live up to its new image? Can it avoid to dissapoint the people finally giving it a try?

Well, the "It doesn't have a nice, easy to use desktop" and "There are no applications for it" arguments are vanishing in a puff of colorful smoke and the "It's too hard to install" problem is quietly dissolving. But there's still that nasty "But I can't play my favourite games in Linux!" thing.

Linux has games. Linux has good games. But that other operating system has several orders of magnitude more good games than Linux. That's bad. And difficult to overcome, as it's not only because of technical reasons. But we, the free software community, have have a long history of solving But we, the free software community, have have a long history of solving problems and shipping around obstacles. There is no reason why we should not be able to solve this issue, too.

So what's the current situation, what needs to be done and what can be done? Here is a short overview of the major issues:

• Despite Linux's rapid growth - both in terms of user base and existing software - it still is not generally perceived as viable platform for high quality games. Some of the often cited problems are without doubt true, but most of these are already at the verge of being solved and the others mainly need more public discussion.
• While many game-related SDKs and applications exist or are in the make, there is no comprehensive overview of them available.
• As all of these SDKs have their strengths and weaknesses, much can be gained by making them as modular and interoperable as possible, so that game developers can combine them to an almost optimal solution.
• For both commercial game developers wanting to port games to Linux and yet-inexperienced Open Source® developers aspiring to write free games, easy to read documentation and online help via mailing lists and/or irc are very valuable.

Quick Summary

In essence we are suggesting that this new Linux Game Development Center be a kind of meta-project. It would be dedicated to advocating Linux as gaming platform, collecting knowledge about Linux game development and using it to help all interested people, providing facilities for discussion to Linux game developers and, last but not least, encouraging and helping existing free (Open Source®) game SDK projects coordinate with one another.

Please note that this is not an attempt to impose standards or rules on anyone. We just want to do what we can to help everybody coordinate their project with the others and to encourage all game SDK developers to develop compatible libraries.

This is also a call for developers, users and game SDK projects to join our efforts.

History

In the beginning ... there were many unrelated games SDK projects started by many different groups with little or no inter-group communication or coordination.

The initial initiative of starting the Linux Game Development site came from Ian Crawford (you can read his announcement of the site here).

It was first meant as a meeting and coordination point for people developing native and free Linux games, but its scope was soon widened to support Linux game development in general - the phrase "This site aspires to be the headquarters for all Linux game development" is from that time.

Cut - Switch to the PenguinPlay mailing list. Shortly after Ian's announcement of the site, Sam Lantiga suggested on the PenguinPlay mailing list that people could get together on IRC to discuss the future of Linux game development. His idea was considered as "really good" and after the first meeting the thing was extended to all people involved in pushing game development for Linux. Here are the archives of past meetings and the plans for future ones.

Well, the irc meetings became a regular event (each Saturday) and the possibility to have a real-time discussion through irc gave a big push to our work. We started discussing on how we could coordinate our efforts better, how to make Linux more appealing to professional game developers etc. After a few meetings we came to the conclusion that it would be best to merge the SDK projects (ClanLib, CrystalSpace, GAMES and PenguinPlay) to one, giving it the full support. It seemed to be the right thing, but we were a bit uneasy with it, as merging projects is a very, very difficult task.

Then Charles Durst threw in an proposal for a clearing house project, i.e. a project that would give developers from different game SDK projects a good way to communicate with each other, remind these developers to keep the different SDKs compatible to each other etc. He first proposed that PenguinPlay could become this "meta-project", but we found Ian Crawford's "Linux Game Development Center" much more fitting.

We started working on the homepage for this and Charles wrote an announcement text we wanted to post on Slashdot or Freshmeat and several newsgroups. However, as we assembled material for the homepage, discussed its structure etc it slowly mutated from the "Linux Game SDK Coordination Center" to a site for Linux game development in general - the "Linux Game Development Center" or LGDC for short. Ian's original site laid the foundation for this (as it was aimed at helping people to develop actual games) and the transformation was completed when the "Linux Game Breeding (LGB)" (aimed at creation of new projects around Linux GameDev) and "Linux Gaming Awareness (LGA)" (aimed at advocating Linux to commercial game developers) projects joined in.

So here we are. The Linux Game Development Center is a project from Open Source® game developers, maintained by them and dedicated to all people interested in the subject. Located at www.linuxgames.org, it serves as a sister site to www.linuxgames.com, the already well-established site targeted towards game players.

The Proposal

The new Linux Game Development Center would:

• Maintain a collection of links to various game SDK projects and a "news page" of the current status and functionality of each.
• Help coordinate efforts to increase compatibility and perhaps create "glue" software between the libraries produced by different game SDK projects.
• Help game SDK developers coordinate with one another (via mailing lists and perhaps IRC get-togethers), and share algorithms and code. This could even help SDK developers abstract out new layers of common or overlapping functionality between projects.
• Help to fill the functionality gaps that are currently preventing any combination of game SDK libraries from being comprehensive enough for many professional game developers to use.
• Help to direct game developers to the right tools for their particular tasks. Making it easy to find software for a particular purpose, within certain platform, language or license requirements. We are considering using existing web-based knowledge base tools such as WikiWikiWeb or faq-o-matic, as well as tables of the features and limitations of each available package.
• Collect the general feedback that game developers might want to give the Linux community about any porting problems they might have. And helping to start, extend or fix projects to meet those needs.
• If neccessary initiate and host "please port this to Linux" petitions and mane the commercial game developers aware of the demand.
• Find volunteers willing to port commercial games to Linux and act as mediator between them and commercial game houses.
• Provide facilities for discussion between commercial game developers and Linux users on how support for Linux can be increased in the future.
• Help rally game SDK development efforts to port existing game libraries to needed, unsupported platforms.
• It could help direct interested people to other projects as needed to help with bugfixing, porting, and documentation (especially with respect to interoperability between projects).
• It could even have a relationship to game SDK projects and Open Source® games somewhat similar to the relationship Debian has with the packages that it collects. It could collect easy-to-find and easy-to-install packages of game SDKs and try to make it easy for a new developer to choose the one(s) that best meets their needs. It could even help develop policies to ensure clean interaction between libraries wanting to be added to the collection.

While game development for Linux would be an important goal of the web site, the most important goal would be the development of quality cross-platform game libraries. For that reason, developers of games and game SDKs for platforms other than Linux would be more than welcome to join us. Especially if they are interested in porting software to or from Linux.

In the end, there would still be multiple, competing game SDK packages, but that should be OK as long as at least one comprehensive open-source solution can be cobbled together from the pieces. As we have seen with multiple distributions, and even the KDE/GNOME projects, competition can sometimes be a very good thing ... if you can see past the flame wars.

The biggest problem with having multiple, competing projects is the resultant (developer and user) confusion. What we are proposing is a Linux Game Development Center that is aimed simply at reducing that confusion by helping people to find, evaluate, combine and use the available tools, or to develop new, missing ones.

Request

At this point, we are mainly looking for:

• More people to work on the web-site (in particular people who have ideas for ways we should do it with existing or new web server and/or database technologies).
• Other game SDK related projects that should be added, or who want to help, or who should at least join the linuxgames mailing list(s).
• Other Game or Game SDK developers who want to be in on the discussions, prioritizing, development, or who just want to influence the direction of the Linux Games project in one way or another.

All interested people are invited to join the linuxgames mailing list and participate in the discussions (send a blank message to linuxgames-subscribe@sunsite.auc.dk)
