The Hospitality Club became the first hospitality exchange network to pass the 100,000 members milestone on January 11, 2006. Its closest competitors, CouchSurfing and GlobalFreeLoaders, have 40,000 and 30,000 members.

Hospitality exchange organisations are dedicated to putting travellers in contact with locals offering to host them in their house for free, or simply offer them a tour of their city or share a meal with them. Besides the obvious financial advantage, the Hospitality Club believes that “bringing people together and fostering international friendships will increase intercultural understanding and strengthen peace.”

Servas Open Doors, the oldest network, in fact formally views itself as a peace initiative, and there are also a number of smaller hospitality exchange networks which focus on specialized audiences, such as Agritourism.

w:Veit Kühne from Dreseden, Germany, who founded the Hospitality Club in 2000 while he was still a student, believes that “one day, everyone will have the opportunity to visit any country knowing that someone will be waiting to receive them with open arms. People will travel in a different way, meet each other and build intercultural understanding through personal contact.”

“There will be many members in places like Israel and Palestine, Northern Ireland, the Balkans, Chechnya, Rwanda, or Timor who will exchange hospitality with each other, and in small steps the Hospitality Club will have helped making peace a lasting vision for our wonderful planet,” he adds.

Hospitality Club was the first online organisation to offer on a major scale the possibility for travellers to find and contact locals open to cultural exchange. The whole system is entirely free, and hosting fees are supported by Google advertisements. The safe and efficient operation of the 30+ languages website and its database, forum, and chatroom depends on the work of hundreds of volunteers from around the world.

Anybody can become a member, but they must provide their full name and address, for security reasons. All members have a profile they can fill with information about themselves and their preferences, to help prospective visitors contact the person most likely to welcome them.

The most often mentioned drawback of the system is lack of security. The main difference between hospitality exchange networks and other social networking platforms such as Orkut or LiveJournal is that the former’s ultimate objective is to allow for face-to-face meetings. Users should realise that there is a risk involved, although according to Frenchman Jean-Yves Hégron, main software developer of the Hospitality Club, “By using the Club you have the same level of risk as the one you face whenever you get out from your home.”

Discussion about strategic or security issues is not allowed on the website’s forum, hence critics often mention lack of transparency in how they perceive decisions are taken by volunteers in Hospitality Club. Another point of critique is the fact that there is no legal organisation behind Hospitality Club, and the domain name is registered to the founder of the Club himself. Messages containing links to other hospitality exchange networks were at some point deleted without further notice though this policy has since then been reverted. Exponential growth of the network has also caused server failures alike to those observed in Wikipedia until recently.

The idea of free hospitality exchange is not new. Servas was the first organisation to develop it, right after World War II. It still exists to this day, with over 15,000 members, and is represented as an NGO in the United Nations. Because democratic, paper-based Servas is perceived as bureaucratic by some, Hospex was created as the first online network in 1991.

Hospitality Club succeeded to Hospex in August 2000, introducing innovative security features ranging from spam protection to passport control and a sophisticated feedback system, thus making online hospitality exchange available to travellers with higher safety concerns. From 1000 members in July 2002 to 10,000 in February 2004, it quickly grew to 100,000 on 11 January 2006 and is expected to reach the million in about two years.

More than 50 programmers, scientists, students, hobbyists and fans of the A.L.I.C.E. chat robot gathered in Guildford, U.K. on Friday to celebrate the tenth birthday of the award winning A.I. On hand was the founder the Loebner Prize, an annual Turing Test, designed to pick out the world’s most human computer according to an experiment laid out by the famous British mathematician Alan Turing more then 50 years ago. Along with A.L.I.C.E.’s chief programmer Dr. Richard S. Wallace, two other Loebner prize winners, Robby Garner and this year’s winner, Rollo Carpenter, also gave presentations, as did other finalists.

The University of Surrey venue was chosen, according to Dr. Wallace, not only because it was outside the U.S. (A.L.I.C.E.’s birthday fell on the Thanksgiving Day weekend holiday there, so he expected few people would attend a conference in America), but also because of its recently erected statue of Alan Turing, who posed the famous A. I. experiment which inspired much of the work on bots like A.L.I.C.E. University of Surrey Digital World Research Centre organizers Lynn and David Hamill were pleased to host the event because it encourages multi-disciplinary interaction, and because of the Centre’s interest in interaction between humans and computers.File:ALICE Birthday Cake.jpg

Dr. Wallace gave a keynote address outlining the history of A.L.I.C.E. and AIML. Many people commented on the fact the he seemed to have moved around a lot in the last ten years, having lived in New York, Pennsylvania, San Francisco, Maine, Amsterdam and Philadelphia, while working on the Alicebot project. The A.L.I.C.E. and AIML software is popular among chat robot enthusiats primarily because of its distribution under the GNU free software license. One of Dr. Wallace’s PowerPoint slides asked the question, “How do you make money from free software?” His answer: memberships, subscriptions, books, directories, syndicated ads, consulting, teaching, and something called the Superbot.

Rollo Carpenter gave a fascinating presentation on his learning bot Jabberwacky, reading from several sample conversations wherein the bot seemed amazingly humanlike. Unlike the free A.L.I.C.E. software, Carpenter uses a proprietary learning approach so that the bot actually mimics the personality of each individual chatter. The more people who chat with Jabberwacky, the better it becomes at this kind of mimicry.

In another interesting presentation, Dr. Hamill related present-day research on chat robots to earlier work on dialog analysis in telephone conversations. Phone calls have many similarities to the one-on-one chats that bots encounter on the web and in IM. Dr. Hamill also related our social expectations of bots to social class structure and how servants were expected to behave in Victorian England. He cited the famous Microsoft paperclip as the most egregius example of a bot that violated all the rules of a good servant’s behavior.

Bots have advanced a long way since philanthropist Hugh Loebner launched his controversial contest 15 years ago. His Turing Test contest, which offers an award of $100,000 for the first program to pass an “audio-visual” version of the game, also awards a bronze medal and $2000 every year for the “most human computer” according to a panel of judges. Huma Shah of the University of Westminster presented examples of bots used by large corporations to help sell furniture, provide the latest information about automotive products, and help customers open bank accounts. Several companies in the U.S. and Europe offer customized bot personalities for corporate web sites.

Even though Turing’s Test remains controversial, this group of enthusiastic developers seems determined to carry on the tradition and try to develop more and more human like chat bots.Hugh Loebner is dedicated to carry on his contest for the rest of his life, in spite of his critics. He hopes that a large enough constituency of winners will exist to keep the competition going well beyond his own lifetime. Dr. Wallace says, “Nobody has gotten rich from chat robots yet, but that doesn’t stop people from trying. There is such a thing as ‘bot fever’. For some people who meet a bot for the first time, it can pass the Turing Test for them, and they get very excited.”

After windy and stormy conditions in Florida prevented its planned landing at Kennedy Space Center, the National Aeronautics and Space Administration (NASA) decided to redirect the space shuttle Endeavour to California. It touched down successfully at Edwards Air Force Base at 1:25 p.m. local time, or 21:25, November 30, 2008 (UTC).

NASA normally prefers to land space shuttles at its home base, Kennedy Space Center. In this case, NASA will have to transfer Endeavour atop a jumbo jet from California to Florida at an estimated cost of US$1.8 million.

NASA had launched mission STS-126 on November 14 with eight astronauts led by Commander Christopher J. Ferguson. The mission was intended to make improvements to the International Space Station, including a new bathroom, sleeping quarters, and urine recycling system. The crew also successfully cleared metal shavings from a jammed solar wing rotary joint, which had affected energy production.

Upon the landing, Mission Control radioed, “Welcome back. That was a great way to finish a fantastic flight.”

“And we’re happy to be here in California,” replied Ferguson.

Companies in the United States are shedding more jobs, pushing the country’s unemployment rate to a 26-year high of 9.8%.

The US Labor Department said on Friday that employers cut 263,000 jobs in September, with companies in the service industries — including banks, restaurants and retailers — hit especially hard. This is the 21st consecutive month of job losses in the country.

The United States has now lost 7.2 million jobs since the recession officially began in December 2007. The new data has sparked fears that unemployment could threaten an economic recovery. Top US officials have warned that any recovery would be slow and uneven, and some have predicted the unemployment rate will top 10% before the situation improves.

“Continued household deleveraging and rising unemployment may weigh more on consumption than forecast, and accelerating corporate and commercial property defaults could slow the improvement in financial conditions,” read a report by the International Monetary Fund’s World Economic Outlook, predicting that unemployment will average 10.1% by next year and not go back down to five percent until 2014.

Mark Zandi, chief economist at Moody’s Economy.com, said that “it’s a very fragile and tentative recovery. Policy makers need to do more.”

“The number came in weaker than expected. We saw a lot of artificial involvement by the government to prop up the markets, and now that that is starting to end, the private sector isn’t yet showing signs of life,” said Kevin Caron, a market strategist for Stifel, Nicolaus & Co.

Also on Thursday, the US Commerce Department said factory orders fell for the first time in five months, dropping eight-tenths of a percent in August. Orders for durable goods — items intended to last several years (including everything from appliances to airliners) — fell 2.6%, the largest drop since January of this year.

The US government has been spending billions of dollars — part of a $787 billion stimulus package — to help spark economic growth. There have been some signs the economy is improving.

The Commerce Department said on Thursday that spending on home construction jumped in August for its biggest increase in 16 years. A real estate trade group, the National Association of Realtors, said pending sales of previously owned homes rose more than 12 percent in August, compared to August 2008.

A separate Commerce Department report said that consumer spending, which accounts for more than two-thirds of US economic activity, rose at its fastest pace in nearly eight years, jumping 1.3 percent in August.

Other reports have provided cause for concern. A banking industry trade group said Thursday the number of US consumers making late payments, or failing to make payments, on loans and credit cards is on the rise. A survey by a business group, the Institute for Supply Management, Thursday showed US manufacturing grew in September, but at a slower pace than in August when manufacturing increased for the first time in a year and a half.

Stock markets reacted negatively to the reports. The Dow Jones Industrial Average fell 41 points in early trading, reaching a level of 9467. This follows a drop of 203 points on Thursday, its largest loss in a single day since July. The London FTSE index fell 55 points, or 1.1%, to reach 4993 points by 15.00 local time.

Thailand’s prime minister, Abhisit Vejjajiva, has ruled out a compromise offer by anti-government protest leaders for parliament to be dissolved in thirty days, with elections to be held in 90 days.

In a televised address on Sunday, with army chief General Anupong Paochinda at his side, the prime minister dismissed the offer made by the National United Front of Democracy Against Dictatorship (UDD), saying such issues could not be resolved in such a short period of time, and “because they use violence and intimidation. I cannot accept this.”

Abhisit said the government stood by an offer made during earlier talks with the UDD for the house to be dissolved within the next nine months.

In reaction, the UDD, also called the Red Shirts, maintained an earlier call for parliament to be dissolved immediately. The UDD also withdrew from any further negotiations with the government. UDD leaders have repeatedly warned supporters rallying in central Bangkok’s retail and business areas of the threat of a new government crackdown.

There have been two large incidents of street violence in the past month or so, resulting in 26 deaths and injuries to hundreds of people. The Red Shirts primarily consist of supporters of former prime minister Thaksin Shinawatra, ousted in a 2006 coup. He was later given a two-year prison term on charges of corruption, although Shinawatra left the country in self-exile to avoid being jailed.

With a fourth-quarter investment earnings of $3.9 Billion CAD, largely driven by stock market rises, the Canada Pension Plan’s (CPP) assets rose to $140.1 Billion reported the CPP Investment Board on Thursday.

Rate of return for the quarter netted three percent, bringing the first nine months of the fiscal year to 8.3%. The fund’s broad exposure to equities, in concert with a good quarter for stocks both in Canada and internationally, was largely to be credited according to CEO David Deneson.

The assets value rose from $127.6 Billion March 31st 2010, to $138.6 B on September 30th, to $140.1 B December 31st. The $3.9 B investment earnings, 3.58 of which came from the 54% of the portfolio in equities, was partially offset by seasonal outlays of $2.4 B to plan members.

The fund was very active throughout the calendar year, and particularly active in infrastructure, real estate, and private equity. As part of a consortium they completed the $4.8 B purchase of UK-based Tomkins plc, as well as purchasing Australian-based Intoll for $3.4 B thus acquiring a 30% stake in the 407 Express Toll Route (ETR) near Toronto — which they expanded purchasing a further 10% stake from Spain’s Concesiones de Infraestructuras de Transporte, S.A. (CINTRA). They acquired a 25% equity stake in Westfield Stratford City, a retail complex adjacent to London’s Olympics venue, among many real estate ventures.

The CPP fund covers every province except Quebec, whose Caisse de Depot et Placement du Quebec is the only larger pension fund in Canada. The five-year annualised investment rate of return for the CPP reserve fund was 3.5%, its 10-year rate of return was 5.6%, at the close of 2010. The fund was established in 1997.

A trustee of the estate of the late author Adrian Jacobs filed a lawsuit against the US publisher of the Harry Potter series, Scholastic Inc, on Tuesday. He claimed that J. K. Rowling, the author of the Harry Potter series, had copied scenes from Jacob’s novel, The Adventures of Willy the Wizard, to the fourth novel of the series, Harry Potter and the Goblet of Fire. The suit followed a similar case last year, in which the trustee sued the UK publisher of the series, Bloomsbury Publishing plc. Both of these cases are currently pending.

The complaint stated that in both books, the protagonists “are required to deduce the exact nature of the central task in the competition”, and had done so in a bathroom. Both books also involved “rescuing hostages imprisoned by a community of half-human, half-animal creatures.” The suit also claimed that Christopher Little, a literary agent of Rowling, was originally the literary agent of Jacobs. The claim was denied by Scholastic.

Scholastic called the claim “completely without merit”. They pointed out that Rowling had said in February that she had never read Jacobs’ book. The trustee said that the US was the world’s largest foreign market, so they brought their first overseas action there. He demanded that all copies of the Harry Potter novel be destroyed, and all the profit made by the book given to him.

A robotic system at Stanford Medical Center was used to perform a laparoscopic gastric bypass surgery successfully with a theoretically similar rate of complications to that seen in standard operations. However, as there were only 10 people in the experimental group (and another 10 in the control group), this is not a statistically significant sample.

If this surgical procedure is as successful in large-scale studies, it may lead the way for the use of robotic surgery in even more delicate procedures, such as heart surgery. Note that this is not a fully automated system, as a human doctor controls the operation via remote control. Laparoscopic gastric bypass surgery is a treatment for obesity.

There were concerns that doctors, in the future, might only be trained in the remote control procedure. Ronald G. Latimer, M.D., of Santa Barbara, CA, warned “The fact that surgeons may have to open the patient or might actually need to revert to standard laparoscopic techniques demands that this basic training be a requirement before a robot is purchased. Robots do malfunction, so a backup system is imperative. We should not be seduced to buy this instrument to train surgeons if they are not able to do the primary operations themselves.”

There are precedents for just such a problem occurring. A previous “new technology”, the electrocardiogram (ECG), has lead to a lack of basic education on the older technology, the stethoscope. As a result, many heart conditions now go undiagnosed, especially in children and others who rarely undergo an ECG procedure.
