brindafella writes: Earthquakes are telling scientists more about the core of the Earth, specifically that it is squishier than previously thought (by about 2.5%.) Associate Professor Hrvoje Tkali & Thanh-Son Pham of the Australian National University have made sense of data collected by seismographs around the world to put new numbers on the density and pressure of the core. In Science magazine, they show that the pressure is 167.4 +/- 1.6 gigapascals (GPa) in Earth's center. For reference, standard atmospheric pressure is 101,325 pascals (Pa), so the center of the Earth is around 61 million times this pressure, but still 2.5% lower than expected.

An anonymous reader quotes Ars Technica: Two top Australian government officials said Sunday that they will push for "thwarting the encryption of terrorist messaging" during an upcoming meeting next week of the so-called "Five Eyes" group of English-speaking nations that routinely share intelligence... According to a statement released by Attorney General George Brandis, and Peter Dutton, the country's top immigration official, Australia will press for new laws, pressure private companies, and urge for a new international data sharing agreement amongst the quintet of countries... "Within a short number of years, effectively, 100 per cent of communications are going to use encryption," Brandis told Australian newspaper The Age recently. "This problem is going to degrade if not destroy our capacity to gather and act upon intelligence unless it's addressed"... Many experts say, however, that any method that would allow the government access even during certain situations would weaken overall security for everyone.
America's former American director of national intelligence recently urged Silicon Valley to "apply that same creativity, innovation to figuring out a way that both the interests of privacy as well as security can be guaranteed." Though he also added, "I don't know what the answer is. I'm not an IT geek, but I just don't think we're in a very good place right now."

schwit1 writes Scientists doing geothermal research in Australia have discovered evidence of what they think is the largest known impact zone from an meteorite on Earth. The zone is thought to be about 250 miles across, and suggests the bolide split in two pieces each about 6 miles across before impact. The uncertainty is that the evidence for this impact is quite tentative: "The exact date of the impacts remains unclear. The surrounding rocks are 300 to 600 million years old, but evidence of the type left by other meteorite strikes is lacking. For example, a large meteorite strike 66 million years ago sent up a plume of ash which is found as a layer of sediment in rocks around the world. The plume is thought to have led to the extinction of a large proportion of the life on the planet, including many dinosaur species. However, a similar layer has not been found in sediments around 300 million years old, Dr Glikson said. 'It's a mystery – we can't find an extinction event that matches these collisions. I have a suspicion the impact could be older than 300 million years,' he said."

An anonymous reader writes: Physicists at Australian National University have developed a tiny tractor beam that improves in several ways upon previous attempts. First, it operates on scales which, while still tiny, are higher than in earlier experiments. The beam can move particles up to 200 microns in diameter, and it can do so over a distance of 20 cm. "Unlike previous techniques, which used photon momentum to impart motion, the ANU tractor beam relies on the energy of the laser heating up the particles and the air around them (abstract). The ANU team demonstrated the effect on gold-coated hollow glass particles. The particles are trapped in the dark center of the beam. Energy from the laser hits the particle and travels across its surface, where it is absorbed creating hotspots on the surface. Air particles colliding with the hotspots heat up and shoot away from the surface, which causes the particle to recoil, in the opposite direction. To manipulate the particle, the team move the position of the hotspot by carefully controlling the polarization of the laser beam."

Zothecula writes "A team of astronomers at The Australian National University working on a five-year project to produce the first comprehensive digital survey of the southern sky has discovered the oldest known star in the Universe. The star dates back 13.7 billion years, only shortly after the Big Bang itself. It's also nearby (at least, from a cosmological perspective) — about 6,000 light-years away. The star is notable for the very small amount of iron it contains (abstract). The lead researcher, Stefan Keller, said, 'To make a star like our Sun, you take the basic ingredients of hydrogen and helium from the Big Bang and add an enormous amount of iron – the equivalent of about 1,000 times the Earth's mass. To make this ancient star, you need no more than an Australia-sized asteroid of iron and lots of carbon. It's a very different recipe that tells us a lot about the nature of the first stars and how they died.'"

New submitter jaa101 writes "Facebook has refused a request from Australian police to take down a page with details of undercover police vehicles saying it cannot stop people taking photos in public places. The original story is paywalled and it doesn't give a link to the relevant page which seems to be here . This page for the state of Victoria has 12000 likes but a similar page for the state of Queensland has over 34000, and there are other Australian pages too."

tqft writes "What the world needs is more truly random sources of numbers. Researchers from Australian National University have found a brilliant way to make one: 'We do this by splitting a beam of light into two beams and then measuring the power in each beam. Because light is quantised, the light intensity in each beam fluctuates about the mean. Those fluctuations, due ultimately to the quantum vacuum, can be converted into a source of random numbers. Every number is randomly generated in real time and cannot be predicted beforehand.' So if you need some really random numbers, just use their generator service."

hype7 writes "It's clear Steve Jobs didn't pull any punches from the interviews for his forthcoming biography. In the latest release from the book, hosted over at AP, 'Isaacson wrote that Jobs was livid in January 2010 when HTC introduced an Android phone that boasted many of the popular features of the iPhone. Apple sued, and Jobs told Isaacson in an expletive-laced rant that Google's actions amounted to "grand theft." ... "I'm going to destroy Android, because it's a stolen product. I'm willing to go thermonuclear war on this." ... In a subsequent meeting with Schmidt at a Palo Alto, Calif., cafe, Jobs told Schmidt that he wasn't interested in settling the lawsuit, the book says. "I don't want your money. If you offer me $5 billion, I won't want it. I've got plenty of money. I want you to stop using our ideas in Android, that's all I want." The meeting, Isaacson wrote, resolved nothing.'"

hype7 writes "The Harvard Business Review is running an article on Siri, the speech recognition technology inside the new iPhone. They make the case that Siri's use of artificial intelligence and speech recognition is going to change the way we interact with machines. From the article: 'The advantage of using speech over other interaction paradigms is that we have honed its use over thousands of years. It is entirely natural for us to talk to one another. Talking is one of the first things we learn how to do as children. It's second nature for us to ask a colleague or a friend a question and for them to answer the same way. Being able to talk to a phone like it's a personal assistant is something that people are going to get very used to, very quickly. It's a much more natural approach than using a mouse on a desktop. And I highly doubt the impact is going to stop at phones.'"

brindafella writes "Thirteen years ago, two teams of astronomers and physicists independently made the same stark discovery: Not only is the universe expanding like a vast inflating balloon, but its expansion is speeding up. The two teams have now been recognized with the 2011 Nobel Prize in Physics. Half of the prize will go to Saul Perlmutter of Lawrence Berkeley National Laboratory and the University of California, Berkeley, who led the Supernova Cosmology Project. The other half will be shared by Brian Schmidt of the Australian National University's Research School of Astronomy and Astrophysics, who led the High-z Supernova Search Team, and Adam Riess of Johns Hopkins University and the Space Telescope Science Institute in Baltimore, Maryland, who worked on High-z. In essence, they proved that Einstein's 'biggest mistake' (the cosmological constant, to create a 'stable universe') was actually a clever theoretical prediction that there was something else happening — dark energy."

eldavojohn writes "An Australian National University project has completed a proof-of-concept storage unit that relies on bringing light to a standstill inside a crystal and then releasing it later for a read-once storage device. There are a few complexities to work out, such as the -270 degrees Celsius requirement to stop the light. And there is an interesting side effect noted by the team lead: 'We could entangle the quantum state of two memories, that is, two crystals. According to quantum mechanics, reading out one memory will instantly alter what is stored in the other, no matter how large the distance between them. According to relativity, the way time passes for one memory is affected by how it moves. With a good quantum memory, an experiment to measure how these fundamental effects interact could be as simple as putting one crystal in the back of my car and going for a drive.' Hopefully this will lead to a better understanding and simple testing of quantum entanglement."

nuur writes "Researchers at the Australian National University have developed a new form of optical memory that allows random access to stored optical quantum information. Pulses of light are stored on a kind of 'optical conveyor-belt' that is controlled with a magnetic field. By manipulating the magnetic field, the conveyor-belt can be moved, allowing the recall of any part of the stored optical information. The research is published in Nature." You'll probably know after reading the abstract linked whether you'd be in the market to pay for the whole thing.

Ant writes "According to this Discovery Channel article, people are smarter and more creative lying down than standing up. Darren Lipnicki, a researcher from the school of psychology at the Australian National University (ANU) believes this helps to explain Archimedes' eureka moment. He found that people solve anagrams more quickly when they are on their backs than on their feet. His finding relates to the difference in brain chemistry, specifically the release of the neurotransmitter noradrenaline, when lying down or standing up. While noradrenaline is normally associated with cognitive ability and attention, it is also believed to impair creative thinking. And less is released while lying down. (Seen on Shacknews)."

sdedeo writes "Perhaps the only competitor of rock climbing for the canonical geek sport, cycling -- for utility or amusement -- asks for a good blend of engineering and physiological savvy. For many the hands-on tinkering of bicycle maintenance and cycling technique provides welcome relief from more abstract manipulations in the library or office. Whether you think of cycling as the ultimate open source engineering project, or as a handy metaphor for your computer-of-choice, its appeal to the mechanism-oriented mind is undeniable." Read on for the rest of DeDeo's review. Bicycling Science, Third Edition author David Gordon Wilson pages 476 publisher MIT Press rating 10 reviewer Simon DeDeo ISBN 0262232375 summary A technical look at two-wheeled self-propulsion blending engineering and physiological savvy.

Released this April, David Gordon Wilson's updated Bicycling Science fills the gap between, on the one hand, shop manuals and training guides, and on the other the contemporary literature on human powered vehicles. Wilson, Professor Emeritus at MIT, navigates physics and physiology to produce a hefty source of insight.

Wilson splits his book into three broad sections -- the biology of human power generation, the physics of turning complicated muscle motions into linear velocity, and radical redesigns of the standard diamond bicycle frame.

The first section explains, among other things, the role of oxygen uptake and distribution, and gives empirical and theoretical backing to some, but not all, of the conventional wisdom surrounding cycling. The curious will find a detailed explanation of why high pedal cadence allows for long-term, low-intensity, high-efficiency power generation. Modifications to the standard choices -- from elliptical chain-wheels to hand-powered cranks -- are analyzed critically.

The second section might be jokingly termed "extreme high school physics." Wilson explains how people intuitively balance and steer on two wheels, and the design of braking systems to avoid flip-over. He gets down-and-dirty in the metallurgical literature to explain the role of metal fatigue in frame failure, and into fluid dynamics to discuss air drag in laminar and turbulent air flows.

Wilson manages to give a sense of how the different demands physics makes on all aspects of bike design cohere into the more-or-less efficient system that we recognize today as the road and mountain bike. Wilson is an innovator, but he has a healthy respect for current designs along with a good deal of skepticism for passing fads such as that for ultralight components.

The final section covers Wilson's love: the radical redesigns of human powered vehicles to enable people to not only cover vast distances or reach high speeds, but also to swim, submarine, fly and even hover or flap on the power -- between 100 and 700 W -- the "NASA standard" man or woman can provide on timescales between hours and seconds.

The text occasionally jumps into a wider historical and social context to provide lighter relief, such as the diagrams that compare cycling's efficiency to other modes of of transportation (cyclists handily undercut a fully loaded diesel commuter train for calories expended per rider.) Wilson is not amused by those who would compare cyclists to dolphins or hawks in terms of efficiency, distance, or speed -- too bad. A brief rant against cars near the end is the exception to the rule of Wilson's professional, honest style.

Bicycling Science can be used as a handbook for the armchair designer of human powered vehicles. Or, if you prefer, as a way to answer the nagging science questions that arise after a thoughtful bike ride. Perhaps its most inspiring use, however, is as a bed-table compendium of stand-alone investigations into what engineers have come up with on a device that has been perfected, again and again, for decades longer than the internal combustion engine.

brindafella writes "A scientist at the Australian National University's Mount Stromlo & Siding Springs Observatories, Dr Paul Francis, has dicovered a string of galaxies 300 light years long, and further out than they 'should' be. The team were refused time on a US telescope because many American astronomers believed the observations were technically impossible. The findings have been presented at the American Astronomical Society meeting in Atlanta. 'We have detected 37 galaxies and one quasar in the string, but it probably contains many thousands of galaxies.' He said the galaxy string lay 10,800 million light-years away. See the animation here."

Curmudgeon Rick writes "A research group at the Australian National University is getting symmetrical 250K bps at 20km, using "empty" 7MHz-wide broadcast TV allocations in the 45MHz band. Story here, project homepage here. Aim is to put some bandwidth out beyond the reach of the wires, where users are few and far between."

trystanu writes "The Washington Post reports that Google 'will stop accepting advertising from unlicensed pharmacies that have used the Internet to sell millions of doses of narcotics and prescription drugs without medical supervision', following both Yahoo and Microsoft's similar moves last month. The head of Google's U.S. AdWords branch maintains it's not just for the money but that they want their searchers to have the ads most relevant to what they're looking for. It's quite clear some advertisers are using the front door to spam Google rankings. Are some of the 100,000 advertisers now signed up for Adwords tarnishing Google's image at a delicate time?"

zambuka asks: "Recently I was asked about pricing and availability of wireless microphones. What is needed are 15 wireless microphones, appropriate base units and the ability to record the signal from each microphone on a separate track. A session will last about 2 hours and the results need to be recorded to a CD. I have priced this at about $25000AUS probably less with bulk rates for the mikes and transmitters but still a big cost and not particularly portable for the base and recording units. The question I have regards alternatives. I have thought about using MiniDisc recorders, Nomad and Muvo. These are a much cheaper alternative and will suffice but require a major effort to transfer everything back to a PC and burn to a CD. I was also looking at wireless networks: 802.11a/b and Bluetooth and thought about how much cheaper and more suited to my needs this technology seems to be. Can these wireless systems cope with the constant throughput I need for this? And, is it possible (preferably with off the shelf components) to set up a wireless VOIP or similar network capable of dealing with this quantity of audio and recording the signals separately. Links to the tech would be welcome. Anyone living in Canberra who would like to take a shot at setting something like this up can feel free to contact me."

markthebrewer writes "From an article in the New Scientist: Conventional wisdom every 15 year-old knows says that you can't mix oil and water without some kind of surfactant. However a team lead by Richard Pashley from the Australian National University in Canberra have done it simply by first removing all dissolved gases from the water. Apart from the obvious potential improvements in salad dressings, it could have an impact on the manufacture of everything from drugs to paint - anywhere an emulsion is required. Apparently, it will also give some insight into the mysterious 'long-range hydrophobic effect' (or why oil droplets coalesce over surprisingly long distances)." Keep in mind the usual scientific caveat: this experiment doesn't seem to have been replicated by other experimenters yet.

Slashback tonight with followups on previous stories about tablet computers, the fire at Mt.Stromlo, and Mandrake Linux -- read below for the details. Update: 01/24 00:08 GMT by T : One more update added below, regarding the post earlier this week on nVidia's new video card.

The silver lining.dragonsister writes "Regarding the recent slashdot story on Mount Stromlo Observatory being hit by fire, it seems the damage is not nearly as extensive as it might have been. The Australian National University has posted details here. In particular, the office buildings were spared, meaning that the work of staff and students is safe, and the many years worth of data collected should still be usable. The main question remaining in my mind is whether or not there were backups of the data on the computers that were actually located in the telescope buildings themselves, as these contained information crucial to the interpretation of some of the data. The importance of off-site backups has just been demonstrated. Everybody backup now!"

And blakduk writes "We were able to enter the site and retrieve computing equipment that survived the fire. This enabled us to set up our servers and have all staff back on-line within 24 hours."

Other than that, how was the parade? Back in November, I posted an article about the DocuNote, an inexpensive tablet PC available with Linux. According to richardbondi , maybe "cheap" would be a better word. He writes:

"I bought one, it arrived today. It was clearly used, not new, and didn't work. If you tilted it, it hung. I gave up after a dozen reboots. Only purchasable from www.microsono.com, where all sales are final.

The handwriting recognition software turned out to be trialware.

And although the stepupcomputing.com site says it works with Windows 2000, it came with a note that said now it has to be OEM installed.

One user's bad experience -- bad hardware, deceptive advertising re software."

Looks nice over two monitors, too. Znonymous Coward writes "Mandrake is trying to prove it's not dead yet. Yesterday[Note: the 19th, that is], they released Beta 2 of Mandrake 9.1. You can get the 2 ISO images from the usual mirrors." There's a (critical but mostly positive) review of this 2nd beta running at DistroWatch, too.

Once this starts it always gets messy. Per Hansson writes

"Yesterday we at Techspot posted a Interview with Nvidia plus high-resolution pictures of the Geforce FX.

Anthony writes "The historic Mt Stromlo observatory has been destroyed by fires. Unfortunately Google cache and similar archives are the only available detailed information. Looks like the web site was housed at the observatory. Telescopes housed there were 74" and 50" reflectors along with the "Oddie" 9" refractor used by the Canberra Astronomical Society. Also destroyed were a number of student houses and workshops. The view from the air is one of molten domes and twisted metal. These fires have already destroyed 388 houses in the suburbs of Canberra. Luckily the winds have not picked up today, but the danger is still high."

Slashback tonight with several updates, ranging from patent encumbrances to SOAP 1.2 to the transcript for Eldred v. Ashcroft, with more bits in the middle on the recent Geek Cruise in the Caribbean, the all-important cable TV lineups, and more. Read on below for the details! A little light reading. hayek writes "The transcript of oral argument at the Supreme Court in Eldred v. Ashcroft is now available online."

And then we saw the sharks. a9db0 writes "Part II of Doc Searl's travelogue recounting his experiences on the Geek Cruise has been posted here by the fine folks over at the Linux Journal"

In an earlier report from Geek Cruise, Linus predicted 2.6 by June 2003. If you liked the list of features being considered for 2.6, you can thank puriots0 for "the list of what's been included in time for the feature freeze for Linux 2.6", as found at kernelnewbies.org.

Peel back your eyelids and let these images flood your brain. strredwolf writes "I think we had half the story when Cartoon Network said they were going to remove Zoids and G Gundam in their Toonami block. It was more like remove Zoids, move G Gundam to Midnight Run with GI Joe, put HeMan and Transformers on full weekdays, and double up on DB and DBZ. The website and broadcast prove it now. (This report was done while watching to Toonami live.)"

And Stalke writes "Recently, rumours about Stargate SG1 7th season included it both being renewed as well as speculation that it might be cancelled.

No word about Daniel Jackson returning though :("

Cracking down on alien fraudsters. yep writes "Administrators of the alien-hunting distributed computing experiment SETI@home have announced they will crack down on cheats who rort statistics on computing power lent to the project. The announcement follows a united protest from the chief contributors. SETI@home director David Anderson announced SETI@home would do its best to investigate users returning suspiciously high amounts of work and delete their accounts if it uncovered solid evidence of cheating."

Sure they're not. tiltowait writes "The Hartford Courant article "The FBI Has Bugged Our Public Libraries" has been retracted (this was mentioned here - but the older article has been removed). Even if the retraction can be trusted, this doesn't change the fact that the FBI can still bug libraries as freely as the CIA can assasinate with impunity, or that more McCarthyism is on the way."

This story retracts the claims of bugging made in the previous one. Since the FBI has little incentive to tell the truth on this count, I don't see what incentive anyone has to believe their denial.

Cleaning up the future for SOAP. Makarand writes "A major hurdle in finalizing the SOAP 1.2 specification has been removed. Both Epicentric, a subsidiary of Vignette, and WebMethods, which makes integration software, had said in earlier statements that they may have patents that cover the technology used in the SOAP 1.2 specification which would have made SOAP 1.2 non royalty-free hindering approval by W3C. Epicentric has now amended its earlier statement saying they no longer believe they hold any such patents, and even if they did, they are interested in making them available on a royalty-free basis. WebMethods has made no comments yet."

jorhan writes "Darren Reed, the author of IPFilter, recently posted this message to the IPFilter mailing list. Apparently IPFilter may infringe upon USA patents owned by Bay Networks, specifically, #5790554. The patent might seem to own just about every conceivable way one might wish to filter and forward data packets, but trying to read through all of the "wherein said first condition" started to give me a headache (ObIANAL). But when you read what application the authors specifically had in mind, it really has little to do with network layer firewalling. Even more important is the question Darren's mail indirectly poses, "Anyone know of any prior art?""

Michael Wardle writes "ABC Australia reports that a team of scientists from the Australian National University have successfully teleported a laser beam. It seems that teleportation of solid bodies is still a way off, but at least we're a little closer to Slashdot's favorite super power." Another Australian newspaper has a more detailed story.

Roger Clarke is an computer scientist who attends many of the CFP conferences, and more importantly for our purposes, takes notes. His notes for this year's conference make good reading and cover a wide variety of issues that Slashdot touches upon. Privacy, biometrics, domain names, the digital divide, intellectual property, it's all here. NTK this week has a nice quip on the conference: "And the more the CFPers confer, the more they seemed to realise that Hollywood is going for the hat-trick: taking away freedom, privacy *and* computers. Pretty impressive. But only if they manage it."

Slashback tonight with more on Lord of the Rings (The Two Towers, specifically), various ongoing court battles, the true color of the universe, and more. Read on for the details.

All I'm certain of is my true love's hair. CompaniaHill writes: "As previously reported on /., first they though it was turquoise. Then they found an error in their early calculations, and announced it was really beige. But doubts lingered, and color experts pointed out that an objective color as viewed from the theoretical blackness of space would appear different when viewed on Earth in typical daylight. So adjustments were made, and calculations were revised and rechecked by color scientists Michael Brill of McClendon Automation Inc. and Mark Fairchild of the Munsell Color Science Laboratories. And now, at last, Ivan Baldry and Karl Glazebrook, astronomers at Johns Hopkins University, using spectral data from the 2dF Galaxy Redshift Survey, have announced the final result: The universe is decidedly salmon. Really."

The milestones are getting closer together. Dare Obasanjo writes: "Xindice (http://xml.apache.org/xindice), the Apache native XML database has finally reached version 1.0. Xindice used to be called dbXML and was mentioned in my article on XML and databases."

Three From the Courts TheFrood writes: "It looks as though the battle between Blizzard and bnetd (as reported in previous stories here(1), here(2), and here(3))is heating up. Vivendi has sent another letter to the EFF, which has wasted no time responding."

ElitusPrime writes with an update in the strange case of Ken Hamidi, the Intel employee whose mass-mail to Intel employees brought charges of trespassing. Now the California Supreme Court may take another look at the case. Says ElitusPrime: "If this guy is put in jail, I can think of more then a few other spammers that need to go up the creek with him..."

In a very different case, pagan26 writes: "It seem that DMCA will have its day in court. With ElmcoSoft."

Well, at least you can trust their word, right? Masem writes: "According to MSNBC, the developers of the spyware program WinWhatWhere will no longer have their install program trample the bits of anti-spyware programs, after word broke that this behavior was occurring. However, no word has been made by a similar spyware program developed by SpectreSoft that does similar damage."

I will fork out to see this, happily. Pingsmoth writes "It looks like the faithful fans of Peter Jackson and Tolkien will be able to catch a glimpse of The Two Towers this Saturday. Lordoftherings.net is reporting, through a video of Peter Jackson, that a preview (read: not a trailer) of The Two Towers will be shown in theatres this Saturday, presumably attached to The Fellowship of the Ring. Maybe at the end? At any rate, it looks like I'll be seeing the film at least seven times now, and it's a good thing I got a morning shift tomorrow."

dchat writes: "Roger Clarke, Visiting Fellow, Faculty of Engineering and Information Technology at the Australian National University claims that the "Conventional, hierarchical PKI, built around the ISO standard X.509, has been, and will continue to be, a substantial failure", and then he goes on to explain why. I'd be interested in the views of Slashdot users, as my organisation is contemplating considerable investment in X.500 and PKI (including X.509)." Lots to read here.

Roger Clarke, a computer scientist at Australian National University, was lucky enough to attend the Computers, Freedom and Privacy Conference this year, and has placed his notes online. CFP covered nearly every topic we address in the YRO section of Slashdot, so this is recommended reading for anyone interested in freedom of speech, privacy, encryption, domain names, or a host of other issues. It sounds like Neal Stephenson's address alone was worth the cost of attendance...

Samba developer and LinuxCare employee, Andrew Tridgell, was interviewed on Australian ABC's influential 7:30 Report national current affairs program. "All we need to do is fire up a 98 box and do a domain log-on," Tridge said. Thanks to Paul "Rusty" Russell for finding this.

himi writes "After his articles on what was wrong with the Star Wars movies were linked here, David Brin's mailbox got flooded - as per usual. He's posted an interesting reply to most of the points raised in those emails. It's a good read, even if you don't agree with him. "

st. augustine writes "Australian astronomers have discovered that some black holes are actually pink. Here's a Wired article, and here's the Australians themselves. I was more excited before I found out they were already expecting the black holes to be blue. "

An anonymous contributor writes "Antony Searle, a physics student at the Australian National University has issued the first public release of BACKLIGHT. From his web page: "In essence a four-dimensional raytracer, [BLACKLIGHT] produces scenes demonstrating the optical effects of special relativity - delayed observation, angular aberration, Doppler shifting and the headlight effect." Check out the Movies section as well. "

kroah sent us a quick message from the Linux-USB list:"Some good news for those of you with iMacs: I have got the keyboard and mouse working on my iMac with Inaky's latest snapshot plus some modifications. The patches can be acquired here. uusbd-imac-981209.patch.gz - patches to the recent uusbd snapshot. Note that Inaky and I are still working on merging this stuff back into his tree, and not all the issues are resolved yet, so it is all liable to change. kbd-981208.patch.gz - a patch to the linux kernel source to add support for multiple keyboards. This patch should apply cleanly to recent kernels (either the official source or the vger source), i.e. 2.1.129 or later. I plan to release a precompiled kernel for the iMac along with some installation notes soon." Linux/iMac running 2.2 for Christmas?

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)

Microsoft expects Windows to have competition from Linux, according to its annual filing with the Securities and Exchange Commission: "Over the past year the Linux operating system has gained increasing acceptance, and leading software developers such as Oracle and Corel have announced that they will develop applications that run on Linux." Indeed, the first salvo of the war has perhaps been launched with the recent changes to the smb encryption defaults making Samba more difficult for newbie system administrators to setup (section 8 of the current samba-bugs FAQ) Thanks to Oxymoron ;-) for the second reference.

Ken MacLeod writes "In an item on Friday, you linked to Rob Huffstedtler's proposal for an Open-Source Notes-like messaging project, Rob compared his proposal to Yoga but missed comparing it to Casbah, so the Casbah Project came up with sort of a counter proposal describing how Rob's suggestions could possibly be implemented using Casbah.

Ok, I've been working like a madman to get caught up, and I have several things worth mentioning, but don't want to post so many articles. Normally I don't do quickies mid day, but if I don't, I'll never catch up *grin*. First Jan Csernoch wrote in to tell us about his c64 site which contains tons of stuff about the classic machine that I'm sure alot of you folks logged some serious time with. Chris sent us a link to Mr. Bunny's Guide to ActiveX. Kurt (another one of my roomies) bought this book. It is great fun, especially if you've ever had to code ActiveX, but even if you haven't, you'll enjoy it. John Gotts posted a page of Pictures from LinuxExpo for those who might be interested. Roddy Richards wrote in to tell us that they have released the source (GNU GPL) to NetStat, they're network monitoring stuff. He warns that some IPs may not be resolving properly right now though. Finally, Jules wrote in to tell us that the Gnoutes project (we announced it yesterday- it aims to do Lotus Notes like stuff) has been renamed to Yoga.

Paul Matthews writes "A lot of slashdot readers don't like Notes, but although Lotus' implementation of Notes is rather bad, the concept behind the product is quite sound.

At the moment the project is completely at the preliminary stages, creating a web site, the mailing list, searching the web for tools, products and programs to assist us in our task. But most importantly, collecting ideas from people. This is a large project and as such we will be identifying parts which can be broken off to become completely independent projects in their own right. Hopefully the results of these subprojects will be usefull to other open source developers, and they will find their way into other open source programs.
