Recently, Finnish open-source video game developer Perttu Ahola discussed Minetest, his “longest ever project”, with Wikinews.

Started in October 2010, Minetest was an attempt by Ahola to create a sandbox game similar to Minecraft. Minecraft is a multi-platform commercial game, which was in alpha version when Ahola challenged himself to create something similar to it from scratch, he told Wikinews.

Minetest is an open-source game, which is free for anyone to download and play. It is written in the C++ programming language, and the source code is available on code-hosting site GitHub. According to Ahola, Minetest attempts to run on older hardware, with limited graphics, but to be accessible to more people: those who have outdated technology, and making it available for no cost. Minecraft, on the other hand, is a paid game, currently costing USD 26.95 for its computer version. Minecraft is currently owned by Microsoft, and performs poorly on older hardware.

A correspondent from French Wikinews contacted Perttu Ahola via Internet Relay Chat a few weeks ago, discussing Minecraft. This interview is built on top of the previous interview, as we take a deeper dive into knowing more about this free game which is about to turn ten years old in a few months.

A team of eight transplant surgeons in Cleveland Clinic in Ohio, USA, led by reconstructive surgeon Dr. Maria Siemionow, age 58, have successfully performed the first almost total face transplant in the US, and the fourth globally, on a woman so horribly disfigured due to trauma, that cost her an eye. Two weeks ago Dr. Siemionow, in a 23-hour marathon surgery, replaced 80 percent of her face, by transplanting or grafting bone, nerve, blood vessels, muscles and skin harvested from a female donor’s cadaver.

The Clinic surgeons, in Wednesday’s news conference, described the details of the transplant but upon request, the team did not publish her name, age and cause of injury nor the donor’s identity. The patient’s family desired the reason for her transplant to remain confidential. The Los Angeles Times reported that the patient “had no upper jaw, nose, cheeks or lower eyelids and was unable to eat, talk, smile, smell or breathe on her own.” The clinic’s dermatology and plastic surgery chair, Francis Papay, described the nine hours phase of the procedure: “We transferred the skin, all the facial muscles in the upper face and mid-face, the upper lip, all of the nose, most of the sinuses around the nose, the upper jaw including the teeth, the facial nerve.” Thereafter, another team spent three hours sewing the woman’s blood vessels to that of the donor’s face to restore blood circulation, making the graft a success.

The New York Times reported that “three partial face transplants have been performed since 2005, two in France and one in China, all using facial tissue from a dead donor with permission from their families.” “Only the forehead, upper eyelids, lower lip, lower teeth and jaw are hers, the rest of her face comes from a cadaver; she could not eat on her own or breathe without a hole in her windpipe. About 77 square inches of tissue were transplanted from the donor,” it further described the details of the medical marvel. The patient, however, must take lifetime immunosuppressive drugs, also called antirejection drugs, which do not guarantee success. The transplant team said that in case of failure, it would replace the part with a skin graft taken from her own body.

Dr. Bohdan Pomahac, a Brigham and Women’s Hospital surgeon praised the recent medical development. “There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Leading bioethicist Arthur Caplan of the University of Pennsylvania withheld judgment on the Cleveland transplant amid grave concerns on the post-operation results. “The biggest ethical problem is dealing with failure — if your face rejects. It would be a living hell. If your face is falling off and you can’t eat and you can’t breathe and you’re suffering in a terrible manner that can’t be reversed, you need to put on the table assistance in dying. There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Dr Alex Clarke, of the Royal Free Hospital had praised the Clinic for its contribution to medicine. “It is a real step forward for people who have severe disfigurement and this operation has been done by a team who have really prepared and worked towards this for a number of years. These transplants have proven that the technical difficulties can be overcome and psychologically the patients are doing well. They have all have reacted positively and have begun to do things they were not able to before. All the things people thought were barriers to this kind of operations have been overcome,” she said.

The first partial face transplant surgery on a living human was performed on Isabelle Dinoire on November 27 2005, when she was 38, by Professor Bernard Devauchelle, assisted by Professor Jean-Michel Dubernard in Amiens, France. Her Labrador dog mauled her in May 2005. A triangle of face tissue including the nose and mouth was taken from a brain-dead female donor and grafted onto the patient. Scientists elsewhere have performed scalp and ear transplants. However, the claim is the first for a mouth and nose transplant. Experts say the mouth and nose are the most difficult parts of the face to transplant.

In 2004, the same Cleveland Clinic, became the first institution to approve this surgery and test it on cadavers. In October 2006, surgeon Peter Butler at London‘s Royal Free Hospital in the UK was given permission by the NHS ethics board to carry out a full face transplant. His team will select four adult patients (children cannot be selected due to concerns over consent), with operations being carried out at six month intervals. In March 2008, the treatment of 30-year-old neurofibromatosis victim Pascal Coler of France ended after having received what his doctors call the worlds first successful full face transplant.

Ethical concerns, psychological impact, problems relating to immunosuppression and consequences of technical failure have prevented teams from performing face transplant operations in the past, even though it has been technically possible to carry out such procedures for years.

Mr Iain Hutchison, of Barts and the London Hospital, warned of several problems with face transplants, such as blood vessels in the donated tissue clotting and immunosuppressants failing or increasing the patient’s risk of cancer. He also pointed out ethical issues with the fact that the procedure requires a “beating heart donor”. The transplant is carried out while the donor is brain dead, but still alive by use of a ventilator.

According to Stephen Wigmore, chair of British Transplantation Society’s ethics committee, it is unknown to what extent facial expressions will function in the long term. He said that it is not certain whether a patient could be left worse off in the case of a face transplant failing.

Mr Michael Earley, a member of the Royal College of Surgeon‘s facial transplantation working party, commented that if successful, the transplant would be “a major breakthrough in facial reconstruction” and “a major step forward for the facially disfigured.”

In Wednesday’s conference, Siemionow said “we know that there are so many patients there in their homes where they are hiding from society because they are afraid to walk to the grocery stores, they are afraid to go the the street.” “Our patient was called names and was humiliated. We very much hope that for this very special group of patients there is a hope that someday they will be able to go comfortably from their houses and enjoy the things we take for granted,” she added.

In response to the medical breakthrough, a British medical group led by Royal Free Hospital’s lead surgeon Dr Peter Butler, said they will finish the world’s first full face transplant within a year. “We hope to make an announcement about a full-face operation in the next 12 months. This latest operation shows how facial transplantation can help a particular group of the most severely facially injured people. These are people who would otherwise live a terrible twilight life, shut away from public gaze,” he said.

On Tuesday, Juventud Rebelde reported that the Central Administration of Cuba is organizing a migration to free and open source software. The announcement was made during a free software workshop organized at the “Convención Internacional Informática 2005” by the director of the state office of information technology, Roberto del Puerto.

The plan is to use the Linux operating system as a base, though the administration currently uses Microsoft Windows. The transition is planned to be slow and involves organizational changes, development and creating a legal framework.

The Linux user base in Cuba is around 1,500 people and has its own Linux distribution. Cuba also has some free software developers and the University of Information Science, with over 6,000 students, has committed one department for the development of programs for Linux which is a good move towards open source

Medical doctors have not been getting the full picture about newly FDA-approved drugs, concludes a research team from the University of California, San Francisco. This is because not all the studies required for FDA approval get published. New drug studies that do see publication tend to be ones where the medicine appears to perform well while poor and middling results are less likely to appear in medical journals. The result appears to be that doctors who read the available literature may get an inflated impression of new medications and may prescribe expensive new drugs in place of older medicines that perform as well or better. As Jordan Lite of Scientific American wonders, are drug companies cherry-picking the studies they publish to make their drugs look better than they actually are?

The University of California team reviewed trials that had supported new drugs approved from 1998 to 2000 and examined 909 trials of 90 medications. The search was conducted upon PubMed and other search tools that a typical medical doctor or patient could access. They concluded that less than half of the studies had been published five years after drug approval and a publication bias existed.

Erick Turner, who coauthored a similar study earlier this year, expressed concerns to Scientific American that the problem was not merely the raw percentage of studies published, but that a disproportionate share of the research that appeared in journals are examples where new medications appear to perform well:

When trials are selectively published … it will skew the efficacy of the drug and make it look like it works better than it does. It’s going to create a lot more enthusiasm among consumers of that information or in the words of Alan Greenspan, ‘irrational exuberance.’

Ken Johnson, senior vice president of the Pharmaceutical Research and Manufacturers of America (PhRMA), defended the pharmaceutical industry by saying FDA review of new drug applications is more important than publishing the results of medication trials in medical journals. Approved medications come with labels that give patients and doctors enough information, assures Mr. Johnson.

Yet concerns about full and appropriate disclosure have been serious enough that a new law was enacted last year. FDA Amendments Act of 2007 (FDAAA) requires that all trials which support FDA-approved drugs be registered at the National Institutes of Health website. The requirement goes into effect this coming Saturday. Congress enacted the legislation in response to hearings that determined pharmaceutical companies were less likely to publish studies that indicated significant side effects. One shortcoming in the legislation, according to UCSF associate professor Ida Sim, is that the FDA is still not required to specify which trials it weighs when considering applications for drug approvals. Yet she praises the new law as a major improvement. It’s critically important that we know trials exist and that we get the summary results, positive and negative, into the public domain—that’s a huge step and more than any [other] country is doing now.

Minas, one of the largest states of Brazil, has stopped the sale of the Toyota Corolla over safety concerns.

The move was made after nine Corolla customers reported that their cars automatically accelerated. The state public prosecutor’s office said in an online statement on Tuesday that the problem is blamed on accelerator pedals sticking underneath floor mats. Local government said the issue was “putting in danger the lives of occupants”.

According to the prosecutor’s office, sales of Corollas may resume when Toyota alters the floormats in its current models. Toyota has recalled over eight million vehicles worldwide due to acceleration problems.

Buffalo, New York —In an unanimous vote, the City of Buffalo‘s Planning Board voted to table the Elmwood Village hotel Proposal, postponing voting on legislation for up to 30 days.

The Board said its decision was due to the lack of public involvement, saying that there have not been enough meetings.

The Elmwood Village Hotel is a proposed project by Savarino Construction Services Corporation and was designed by Karl Frizlen of The Frizlen Group. The hotel would be placed on Elmwood and Forest Avenues in Buffalo, New York. In order for the hotel to be built, at least five buildings, that include both businesses and residents, must be demolished.

The Forever Elmwood Corp. is a Buffalo-based non-profit organization founded in 1994. Justin Azzarella, the Executive Director for the organization voiced support for the proposal, stating: “I am here today to lend Forever Elmwood’s support the hotel project. Particularly, Forever Elmwood is encouraged by the fact that this building follows the more stringent Elmwood Village Design Guidelines. We have been speaking with Savarino Construction, and they have promised us [Forever Elmwood] that they will engage the community further, including the surrounding Block Clubs and businesses. For that reason, while Forever Elmwood is in support of this project and the type of project that it is, we are asking also that the project be tabled so that the community can be further engaged. Specifically the surrounding Block clubs which include the Granger, Claremont, Asland and The Lincoln Parkway Block Clubs.”

“Because of the excellent work that Karl does and the game plan that they have, I think its an ideal use of this particular location. I think that this particular type of development needs to be encouraged and promoted as opposed to roadblocked,” said a man who owns five properties near the proposal site.

However, Evelyn Bencinich, a resident of Granger Place and whose house would be located directly behind the hotel said, “My property value will be depreciated or non-existent because no one is going to want to live behind a multi-story hotel. We are facing up to a year of noisy and dangerous demolition and construction. Children, pets and even drunk rebellers could wander on site and get hurt. Traffic tie-ups caused by large machinery and garbage bins is inevitable. Where will pedestrians walk? We could experience increased unsanitary flooding in our yards and basements due to the digging and cementing for the underground parking garage. Rats will be displaced into the immediate neighborhoods and be in great abundance. Once we get past the year of nightmare construction, what if you build it and they don’t come? We could ultimately have a seven million dollar rooming house on our corner.”

Patty Morris, co-owner of Don Apparel with Nancy Pollina at 1119 Elmwood also asked that the project be tabled saying, “this has only been public knowledge for less than two weeks and the public never saw the redesign. How can you vote on anything that no one has seen yet? The Board cut off Morris saying, “so specifically you don’t have any problem with it [the design] you just…” Morris then said, “Oh I am totally against this project, but thats besides the point isn’t it.”

The planning board is also concerned that the current design may still be too big.

At one point Board member Susan Curran Hoyt said, “we know you’ve cut down your number of rooms on this project, but we still see it doesn’t seem to fit the description of a ‘botique’ hotel,” and asked Eva Hassett, Vice President of Savarino Construction, “we wonder if you could reduce the rooms further.”

“One thing I didn’t talk about was the price levels of these rooms and that will be important to know. The room rate will be somewhere between US$120 and $160 a night, which is about the same price of the Hampton Inn down town and the smaller you make the hotel, the more expensive the rooms will get. We believe that we’ve made a good compromise in terms of the size of the hotel and perhaps botique means different things to different people,” said Hassett.

The board was also concerned that there is not enough parking asking, “are there alternative plans for valet parking off-site, in the event that you have a full hotel or a large event going on?”

“We are exploring several possibilities with respect to additional parking for valet and parking near-by,” replied Hassett. “We are also exploring the possibility of using the rear of 1105 Elmwood for additional parking, which would give us an additional ten or eleven spaces.”

The new design has a total of 55 parking spaces for 72 rooms, with 39 of them underground and the rest on ground level.

Hassett also said that a “parking study” will be done on the area.

Concerns that the second floor of the hotel will be too close to the property of 605 Forest were also brought up. The board asked how far the hotel would be from the property and Karl Frizlen replied saying it would “be approximately five feet from the property line,” but he also admitted that, “I do not know exactly how close the house next door” will be from the hotel, but did say “I think the house is about four or five feet away from the property line and we [the hotel] sit right on the property line.”

The board is concerned the setback from the property is not enough saying the space between the building and the hotel is “pretty narrow.”

The City’s Common Council also agreed to table the proposal also citing the need for more public engagement and the need for more organizations to respond including the Buffalo Preservation Board and the Office of Historic Preservation.

During that meeting, Hassett also said the proposal to try and get a variance to obtain the properties of 605 and 607 Forest were “now off the agenda.”

The Common Council is expected to meet and hold a public hearing about the project and the rezoning of the properties to be demolished (1119-1121 Elmwood) on Tuesday March 7, 2006 at 2:00 p.m. in Council Chambers at City Hall. At the moment the properties are not zoned for a hotel.
