On Monday, October 22, as the latest Wikimedia fundraiser began, Wikinews reporter Brian McNeil thought his own small donation could be turned into a bigger donation by his buying some advertising on a popular website and encouraging others to contribute. With this in mind he approached Howard Tayler, creator of the Schlock Mercenary webcomic.

Tayler’s response was not as McNeil expected, prompting a Wikinews investigation. Tayler refused to help the foundation raise money although he conceded that he does sometimes use the site. Instead he explained that some members of the webcomic community feel slighted by Wikipedia because over 50 articles on webcomics were deemed not to meet their notability guidelines and were deleted during January and February of 2007. Some members of the webcomics community considered this unacceptable. Whilst some of the comic related articles deleted did not qualify for inclusion in the encyclopedia under Wikipedia guidelines, the deletion of a large number of articles in such a short time period struck some webcomics writers and fans as a selective purge.

Much of the criticism has been focused on Wikipedia editor Dragonfiend, who has described notability as “whether a topic has been noted by independent reputable sources”. She has said that “If we include every article that anyone wants to write, then the encyclopedia becomes useless because nobody can find the actual needle of worthwhile information on a topic hidden in that hay stack of trivia.” She has said Wikipedia should only have articles on webcomics like Penny Arcade, Get Your War On, Fetus-X, and Achewood.

This deletion of numerous webcomic articles has not sat well with some in the webcomic community. Modern Tales editor and Websnark blogger Eric Burns has written that “There are people — and Dragonfiend is clearly one of them — who are clearly going through Wikipedia looking for articles that should be weeded out as non-notable. and they’re doing it in fields they clearly — I mean, clearly — have no interest, experience or knowledge.”

Erfworld and PartiallyClips writer Rob Balder has expressed similar viewpoints, calling the deletion of the webcomics articles a “goddamned crime” and describing a “deletionist jihad” by “the politest bunch of book-burning assholes on the planet”. Balder also labelled “Deletionism” as a form of “naughtymancy” magic in Erfworld. Deletionism refers to the Wikipedia ideology that favours relatively rigorous standards for maintaining access to articles, as opposed to inclusionism which favours keeping and amending problematic articles.

There is concern among some webcomic groups that the notability guidelines are too rigorous for the typical webcomic. The standards usually require significant coverage in reliable sources that are independent of the subject, which is rare since even comics with dedicated followings do not always attract mainstream book publishers or reviews from mainstream journalists. It seems that this policy has alienated webcomic artists and fans and discouraged them from contributing to Wikipedia.

Conflicts such as this are not uncommon. Members of a Wikimedia Foundation mailing list pointed to other examples where the application of the rules has been perceived to be selective, leaving other communities disgruntled with a variety of Wikimedia projects, not just Wikipedia.

Australian troops in southern Iraq will shift to an “overwatch” role, says Defence Minister Brendan Nelson. Australia has around 460 troops in southern Iraq engaged in training the Iraq military and guarding Japanese military engineers. Dr Nelson says the soldiers currently on rotation in Iraq as part of Operation Catalyst will soon provide “front-line combat support” for coalition troops.

“We will move some time over the next three to four months pending the movement of the Japanese to supporting the overwatch program,” he told ABC radio. “So what we will be doing is we will be supporting the Iraqi security forces, Iraqi police and Iraqi local government in administering and managing their own affairs. And we will respond to requests from the Iraqi government.”

Overwatch was “a support program” that involved “providing covering fire to coalition allies in Iraq.” The Australian deployment was expected to end around July this year, but Dr Nelson has said the mission would now continue into next year. His statement followed the British announcement that it would withdraw 800 troops from Iraq in the next few months.

“The British and the Americans are looking at significant draw downs in two to three years. We haven’t set any such timeline… I think we will be there into 2007… We haven’t committed to another two to three years unlike the Americans. We take it on a day-to-day, week-to-week, month-to-month basis,” said the Minister.

Dr Nelson ruled out Australian troops being deployed to more dangerous areas, such as Basra, where the British troops have been based. But he declined to say whether the new mission will be more risky. He says “everything the troops do in Iraq is associated with danger.”

On March 7th, Australian Greens Leader Bob Brown slammed the Howard government’s determination to keep troops in Iraq, as American and British troops are withdrawn. “Australian troops are being subject to thoughtless bravado by John Howard and Brendan Nelson and they need to be brought home immediately,” Senator Brown said.

Operation Catalyst is the Australian Defence Force (ADF) contribution to the rehabilitation and reconstruction of Iraq. Operation Catalyst currently comprises approximately 1320 Australian Defence Force personnel.

Torture proliferates American headlines today: whether its use is defensible in certain contexts and the morality of the practice. Wikinews reporter David Shankbone was curious about torture in American popular culture. This is the first of a two part series examining the BDSM business. This interview focuses on the owners of a dungeon, what they charge, what the clients are like and how they handle their needs.

When Shankbone rings the bell of “HC & Co.” he has no idea what to expect. A BDSM (Bondage Discipline Sadism Masochism) dungeon is a legal enterprise in New York City, and there are more than a few businesses that cater to a clientèle that wants an enema, a spanking, to be dressed like a baby or to wear women’s clothing. Shankbone went to find out what these businesses are like, who runs them, who works at them, and who frequents them. He spent three hours one night in what is considered one of the more upscale establishments in Manhattan, Rebecca’s Hidden Chamber, where according to The Village Voice, “you can take your girlfriend or wife, and have them treated with respect—unless they hope to be treated with something other than respect!”

When Shankbone arrived on the sixth floor of a midtown office building, the elevator opened up to a hallway where a smiling Rebecca greeted him. She is a beautiful forty-ish Long Island mother of three who is dressed in smart black pants and a black turtleneck that reaches up to her blond-streaked hair pulled back in a bushy ponytail. “Are you David Shankbone? We’re so excited to meet you!” she says, and leads him down the hall to a living room area with a sofa, a television playing an action-thriller, an open supply cabinet stocked with enema kits, and her husband Bill sitting at the computer trying to find where the re-release of Blade Runner is playing at the local theater. “I don’t like that movie,” says Rebecca.

Perhaps the most poignant moment came at the end of the night when Shankbone was waiting to be escorted out (to avoid running into a client). Rebecca came into the room and sat on the sofa. “You know, a lot of people out there would like to see me burn for what I do,” she says. Rebecca is a woman who has faced challenges in her life, and dealt with them the best she could given her circumstances. She sees herself as providing a service to people who have needs, no matter how debauched the outside world deems them. They sat talking mutual challenges they have faced and politics (she’s supporting Hillary); Rebecca reflected upon the irony that many of the people who supported the torture at Abu Ghraib would want her closed down. It was in this conversation that Shankbone saw that humanity can be found anywhere, including in places that appear on the surface to cater to the inhumanity some people in our society feel towards themselves, or others.

“The best way to describe it,” says Bill, “is if you had a kink, and you had a wife and you had two kids, and every time you had sex with your wife it just didn’t hit the nail on the head. What would you do about it? How would you handle it? You might go through life feeling unfulfilled. Or you might say, ‘No, my kink is I really need to dress in women’s clothing.’ We’re that outlet. We’re not the evil devil out here, plucking people off the street, keeping them chained up for days on end.”

Below is David Shankbone’s interview with Bill & Rebecca, owners of Rebecca’s Hidden Chamber, a BDSM dungeon.

Seven weeks after citizens of the Six Nations of the Grand River reserve repossessed land near Caledonia, Ontario, on February 28, the Ontario Provincial Police, who have authority from a court to arrest the protesters for contempt of court, have yet to act.

On April 11, more than 50 police cruisers, two paddy wagons, and several vans gathered outside an abandoned school on Unity Road in Caledonia. However, reports from last night are that visible police presence is minimal, with just a few police cruisers parked down the road from the protest site.

Before the site was blocked, Henco Industries had begun construction on 10 luxury homes out of a total of 71 scheduled to be built as part of the $6 million Douglas Creek Estates subdivision.

The tract of land under dispute was registered as a land claim by the Six Nations Band Council in 1987 but its status has yet to be settled. The land originally made up part of a large land grant given in 1784 to the Six Nations for services rendered during the American War of Independence. The government and the developer claim that the Six Nations surrendered title in 1841, but the Band disputes this.

The protesters are demanding a nation-to-nation dialogue with the Canadian government and continue to call for a peaceful resolution. Some protesters, however, have stated that if the OPP forcefully try to remove them, they will defend their land with force.

“If they break the peace, we’ll do what we have to do,” said protester Dick Hill. “Things are very tense. We are trying to defend our lands, which were taken from us. Every time we try to stand up for who we are and what we are, they come and drag us away.”

An injunction was issued to the development company a month ago that allowed for the protesters to be removed. Police have not enforced the injunction.

However, David Ramsay, Ontario’s Aboriginal Affairs Minister, said that the province was going to have a meeting with both protesters and developers in an attempt to address their concerns.

“This is a very serious situation. I have to be very hopeful that we’re going to see a peaceful end to this situation. We think we can resolve this by negotiating, and by talking so that’s what we’re doing,” added Ramsay.

A new historic physics record has been set by scientists for exceedingly small writing, opening a new door to computing‘s future. Stanford University physicists have claimed to have written the letters “SU” at sub-atomic size.

Graduate students Christopher Moon, Laila Mattos, Brian Foster and Gabriel Zeltzer, under the direction of assistant professor of physics Hari Manoharan, have produced the world’s smallest lettering, which is approximately 1.5 nanometres tall, using a molecular projector, called Scanning Tunneling Microscope (STM) to push individual carbon monoxide molecules on a copper or silver sheet surface, based on interference of electron energy states.

A nanometre (Greek: ?????, nanos, dwarf; ?????, metr?, count) is a unit of length in the metric system, equal to one billionth of a metre (i.e., 10^-9 m or one millionth of a millimetre), and also equals ten Ångström, an internationally recognized non-SI unit of length. It is often associated with the field of nanotechnology.

“We miniaturised their size so drastically that we ended up with the smallest writing in history,” said Manoharan. “S” and “U,” the two letters in honor of their employer have been reduced so tiny in nanoimprint that if used to print out 32 volumes of an Encyclopedia, 2,000 times, the contents would easily fit on a pinhead.

In the world of downsizing, nanoscribes Manoharan and Moon have proven that information, if reduced in size smaller than an atom, can be stored in more compact form than previously thought. In computing jargon, small sizing results to greater speed and better computer data storage.

“Writing really small has a long history. We wondered: What are the limits? How far can you go? Because materials are made of atoms, it was always believed that if you continue scaling down, you’d end up at that fundamental limit. You’d hit a wall,” said Manoharan.

In writing the letters, the Stanford team utilized an electron‘s unique feature of “pinball table for electrons” — its ability to bounce between different quantum states. In the vibration-proof basement lab of Stanford’s Varian Physics Building, the physicists used a Scanning tunneling microscope in encoding the “S” and “U” within the patterns formed by the electron’s activity, called wave function, arranging carbon monoxide molecules in a very specific pattern on a copper or silver sheet surface.

“Imagine [the copper as] a very shallow pool of water into which we put some rocks [the carbon monoxide molecules]. The water waves scatter and interfere off the rocks, making well defined standing wave patterns,” Manoharan noted. If the “rocks” are placed just right, then the shapes of the waves will form any letters in the alphabet, the researchers said. They used the quantum properties of electrons, rather than photons, as their source of illumination.

According to the study, the atoms were ordered in a circular fashion, with a hole in the middle. A flow of electrons was thereafter fired at the copper support, which resulted into a ripple effect in between the existing atoms. These were pushed aside, and a holographic projection of the letters “SU” became visible in the space between them. “What we did is show that the atom is not the limit — that you can go below that,” Manoharan said.

“It’s difficult to properly express the size of their stacked S and U, but the equivalent would be 0.3 nanometres. This is sufficiently small that you could copy out the Encyclopaedia Britannica on the head of a pin not just once, but thousands of times over,” Manoharan and his nanohologram collaborator Christopher Moon explained.

The team has also shown the salient features of the holographic principle, a property of quantum gravity theories which resolves the black hole information paradox within string theory. They stacked “S” and the “U” – two layers, or pages, of information — within the hologram.

The team stressed their discovery was concentrating electrons in space, in essence, a wire, hoping such a structure could be used to wire together a super-fast quantum computer in the future. In essence, “these electron patterns can act as holograms, that pack information into subatomic spaces, which could one day lead to unlimited information storage,” the study states.

The “Conclusion” of the Stanford article goes as follows:

The team is not the first to design or print small letters, as attempts have been made since as early as 1960. In December 1959, Nobel Prize-winning physicist Richard Feynman, who delivered his now-legendary lecture entitled “There’s Plenty of Room at the Bottom,” promised new opportunities for those who “thought small.”

Feynman was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the superfluidity of supercooled liquid helium, as well as work in particle physics (he proposed the parton model).

Feynman offered two challenges at the annual meeting of the American Physical Society, held that year in Caltech, offering a $1000 prize to the first person to solve each of them. Both challenges involved nanotechnology, and the first prize was won by William McLellan, who solved the first. The first problem required someone to build a working electric motor that would fit inside a cube ¹/₆₄ inches on each side. McLellan achieved this feat by November 1960 with his 250-microgram 2000-rpm motor consisting of 13 separate parts.

In 1985, the prize for the second challenge was claimed by Stanford Tom Newman, who, working with electrical engineering professor Fabian Pease, used electron lithography. He wrote or engraved the first page of Charles Dickens’ A Tale of Two Cities, at the required scale, on the head of a pin, with a beam of electrons. The main problem he had before he could claim the prize was finding the text after he had written it; the head of the pin was a huge empty space compared with the text inscribed on it. Such small print could only be read with an electron microscope.

In 1989, however, Stanford lost its record, when Donald Eigler and Erhard Schweizer, scientists at IBM’s Almaden Research Center in San Jose were the first to position or manipulate 35 individual atoms of xenon one at a time to form the letters I, B and M using a STM. The atoms were pushed on the surface of the nickel to create letters 5nm tall.

In 1991, Japanese researchers managed to chisel 1.5 nm-tall characters onto a molybdenum disulphide crystal, using the same STM method. Hitachi, at that time, set the record for the smallest microscopic calligraphy ever designed. The Stanford effort failed to surpass the feat, but it, however, introduced a novel technique. Having equaled Hitachi’s record, the Stanford team went a step further. They used a holographic variation on the IBM technique, for instead of fixing the letters onto a support, the new method created them holographically.

In the scientific breakthrough, the Stanford team has now claimed they have written the smallest letters ever – assembled from subatomic-sized bits as small as 0.3 nanometers, or roughly one third of a billionth of a meter. The new super-mini letters created are 40 times smaller than the original effort and more than four times smaller than the IBM initials, states the paper Quantum holographic encoding in a two-dimensional electron gas, published online in the journal Nature Nanotechnology. The new sub-atomic size letters are around a third of the size of the atomic ones created by Eigler and Schweizer at IBM.

A subatomic particle is an elementary or composite particle smaller than an atom. Particle physics and nuclear physics are concerned with the study of these particles, their interactions, and non-atomic matter. Subatomic particles include the atomic constituents electrons, protons, and neutrons. Protons and neutrons are composite particles, consisting of quarks.

“Everyone can look around and see the growing amount of information we deal with on a daily basis. All that knowledge is out there. For society to move forward, we need a better way to process it, and store it more densely,” Manoharan said. “Although these projections are stable — they’ll last as long as none of the carbon dioxide molecules move — this technique is unlikely to revolutionize storage, as it’s currently a bit too challenging to determine and create the appropriate pattern of molecules to create a desired hologram,” the authors cautioned. Nevertheless, they suggest that “the practical limits of both the technique and the data density it enables merit further research.”

In 2000, it was Hari Manoharan, Christopher Lutz and Donald Eigler who first experimentally observed quantum mirage at the IBM Almaden Research Center in San Jose, California. In physics, a quantum mirage is a peculiar result in quantum chaos. Their study in a paper published in Nature, states they demonstrated that the Kondo resonance signature of a magnetic adatom located at one focus of an elliptically shaped quantum corral could be projected to, and made large at the other focus of the corral.
