The name Robert Cailliau may not ring a bell to the general public, but his invention is the reason why you are reading this: Dr. Cailliau together with his colleague Sir Tim Berners-Lee invented the World Wide Web, making the internet accessible so it could grow from an academic tool to a mass communication medium. Last January Dr. Cailliau retired from CERN, the European particle physics lab where the WWW emerged.

Wikinews offered the engineer a virtual beer from his native country Belgium, and conducted an e-mail interview with him (which started about three weeks ago) about the history and the future of the web and his life and work.

Wikinews: At the start of this interview, we would like to offer you a fresh pint on a terrace, but since this is an e-mail interview, we will limit ourselves to a virtual beer, which you can enjoy here.

Robert Cailliau: Yes, I myself once (at the 2nd international WWW Conference, Chicago) said that there is no such thing as a virtual beer: people will still want to sit together. Anyway, here we go.

In the town of Weare, New Hampshire, a movement is under way to force Supreme Court Justice David Souter to sell his home for “public benefit,” an expansion of the eminent domain provision in the Fifth Amendment of the US Constitution that the Supreme Court legalized in the controversial 5-4 decision in Kelo v. New London where Souter was on the majority side. In the June 2005 decision this majority ruled that “public use” included “public benefit,” stating that a local council could use the Fifth Amendment to compulsorily acquire private property for the express purpose of selling it to other private parties whose use was expected to yield increased tax revenues. The decision left many worried that homes would be seized for commercial enterprises or that the decision could be used as a means to remove minority property owners deemed inconvenient.

The campaign to have Souter’s house removed is headed by Logan Clements, who is petitioning to replace it with the Lost Liberty Hotel, a tongue-in-cheek name for what he says will be a memorial to lost freedom. Clements already has 188 signatures to put the issue on a ballot, and only 25 are needed. Once it is on the ballot, the measure can be approved as soon as March. Weare has 8,500 residents.

So far, neither Justice Souter nor Kathy Arberg, Supreme Court spokeswoman, have commented on the matter.

2010 Formula One World Championship entrants USF1 have secured an investment deal with YouTube co-founder Chad Hurley, British magazine Autosport have revealed.

Hurley was positive about the future, and hinted at long term involvement with the team.

YouTube was bought out by search engine giants Google in 2006, which has consolidated the video-sharing website as a global phenomenon, valued at $1.65bn. However, its relationship with Formula 1 has not always been rosy. Video rights to Formula 1 are under the strict copyright of Bernie Ecclestone’s FOM concern. Videos of Formula 1 footage posted on the website are soon challenged and removed, however once removed they are soon replaced, due to the sheer number of videos on the site.

USF1 team principle Ken Anderson was positive about the deal, noting that Hurley’s business acumen and experience in setting up a global brand from scratch can be applied to the fledgling team.

Autosport have also revealed that veteran drivers Alexander Wurz and Pedro de la Rosa may be in the running for a seat alongside “an American rookie”. Austrian Wurz has not competed in Formula 1 since 2007 (For Williams in China), and de la Rosa has not raced competitively in F1 since 2006, when he replaced Juan Pablo Montoya at McLaren mid-way through the season.

The other two new entrants for next year, Campos Grand Prix and Manor Motorsport are yet to announce any investment or sponsorship agreements.

Hurley’s involvement is unlikely to see the YouTube logo added to the car as this is a personal involvement independent of his current position with YouTube.

China has pledged US$10 billion in credit to back joint projects with Central and Eastern European countries. Visiting Chinese Premiere Wen Jiabao announced the deal at a business forum in Warsaw, Poland, and said he hopes the deal will facilitate the two sides’ cooperation.

To boost business and trade, Wen said that China wants to help with infrastructure projects, including new technologies and green economy sectors. Also discussed at the Economic Forum was a new investment cooperation fund which would initially boast US$500 million to assist Chinese investments in the region. He also announced a plan to expand the Chinese market with other countries with hopes to build trade exchange to US$100 billion before the year 2015.

“China will work with countries in Central and Eastern Europe to mutually open the markets and to increase the trade exchange to $100 billion before 2015,” Wen said.

He said trade volume between China and central and eastern European countries reached 52.9 billion US dollars in 2011 and had grown 27.6 percent a year on average since 2001, when it was only 4.3 billion US dollars.

Thus far, the largest Chinese investment has been a €1.2 billion (US$1.6 billion) deal made by China’s Wanhua Industrial Group that gained full control of Borsodchem, a Hungarian chemicals firm. Other recent investments were made in Serbia, where a €170 million (US$225 million) bridge was built over the Danube river in Belgrade.

Prime Minister Donald Tusk of Poland happily welcomed the Chinese investment, noting the country’s uprising economy and European leadership role. Both Wen and Tusk enthused about the potential they say their partnership has and encouraged others in the region to form similar agreements.

The Chinese are “very pragmatic” in business, Andrzej Pawelec of Agrihortus company said, who is seeking new partners in China to sell its beverages. “If they see a good and honest business proposal, they are always open.”

Wen started his official visit to Poland on Wednesday. Poland is the last leg of a four-nation Europe tour that included visits to Iceland and Sweden and the opening ceremony of the Hannover Fair in Germany.

General Motors (GM) and Chrysler will receive bridge loans from the government of Canada and the provincial government of Ontario, however no more will be forthcoming from either Canadian or US governments unless the companies can reinvent themselves.

“This is a regrettable but necessary step to protect the Canadian economy. We are doing this on the assumption that we obviously cannot afford either in the United States or Canada a catastrophic short-term collapse.” said Stephen Harper, Prime Minister of Canada.

“We cannot, we must not, and we will not let our auto industry simply vanish. This industry is, like no other, an emblem of the American spirit; a once and future symbol of America’s success,” said Barack Obama, President of the United States. “These companies – and this industry – must ultimately stand on their own, not as wards of the state.”File:Sinsheim quer.jpg

Chrysler will receive CA$1 billion and may in fact be eligible for as much as CA$4 billion. If Chrysler succeeds in the next 30 days with a restructuring plan it would be eligible for a US$6 billion loan. A part of Chrysler’s restructuring plan must include a partnership with Fiat within 30 days to appease the US administration. Fiat is a supplier of smaller fuel-efficient vehicles, and the merger will help Chrysler to be viable in the North American market. A Chrysler court bankruptcy would inevitably lead to it being sold off.

As a part of Chrysler’s restructuring plans, Tom LaSorda, the president of Chrysler announced that Canadian operations would fold if it does not receive both the US commitment of $2.3 billion of aid and a new Canadian Auto Workers CAW contract to reduce all-in costs by CA$19 per hour. As a result of this announcement Chrysler’s auto sales volume in Canada dropped 23% compared to March of 2008.

GM has until the end of May to restructure its company to receive up to CA$7.5 billion. As part of the companies restructuring, General Motor’s chief executive Rick Wagoner was replaced Sunday with Fritz Henderson, the current chief operating officer. Henderson spoke out on Tuesday that GM has submitted a restructuring plan which would close five plants, and this may be increased to meet the requirements for financial aid. He is in full compliance with Obama’s auto task force to seek bankruptcy if GM cannot negotiate with their unions, bondholders and others.

GM recently brought forward the “GM Total Confidence” program providing consumer purchase protection for customers who lose their job for economic reasons within the first two years from purchase. As a result of Chrysler’s restructuring announcement in Canada, GM’s Canadian vehicle sales volume fell only 17.3% compared to 2008, an increase from the previous month.

GM must reduce some of its legacy costs which include its pensions and union health care costs. A part of GM’s ailments arose from investing in supplying truck and SUVs during an economy of high gas prices when consumers were demanding fuel efficient vehicles.

Tony Clement, Canada’s Minister of Industry, is hoping that the CAW will support the restructuring process and re-negotiate their agreement. Whereas a United Auto Workers negotiator has said, “I don’t see how the UAW will do anything until they see what the bondholders will give up.”

The Obama administration is looking toward bankruptcy proceedings for the automakers, “as a mechanism to help them restructure quickly and emerge stronger. [It will] quickly clear away old debts that are weighing them down. What we are asking is difficult. It will require hard choices by companies. It will require unions and workers who have already made painful concessions to make even more. It will require creditors to recognise that they cannot hold out for the prospect of endless government bailouts.” said Obama.

The auto parts suppliers and IT software exporters in India have already been affected by the declining auto sales. GM and Chrysler software contracts provide US$300 to 350 million a year to vendors in India. As well these two major automakers usually award US$1 billion contracts to auto parts suppliers. “We are worried and closely watching the developments in the US to gauge the impact. The decline in auto sales in the US has already hit the order books of Indian suppliers,” said a Delhi auto parts supplier.

“Going forward, the industry will undoubtedly be smaller, but if our efforts are successful it will be viable and it will support good jobs for Canadians,” said Clements.

Betty Sutton, Ohio’s Congresswoman put forward the CARS act which provides a US$3,000 to 5,000 incentive for those who trade in their vehicle for a fuel-efficient car. “It clearly stimulates the economy, and it gets the consumer into the showroom and gets them buying again. But importantly — and this is what I particularly like about it — it really helps the environment quite a bit in two respects.” said William Clay Ford Jr., executive chairman of Ford Motor Co.

Ford Motor Company has not come forward with requests for assistance.

Since December GM and Chrysler have received US$17.4 billion government loans.

Police have been given seven days to question the suspected terrorist who was arrested in Bristol, United Kingdom today.

After the seven days, the suspect will have to be released or charged, unless an extension is granted.

The BBC has reported that the person who was arrested is approximately nineteen years old. He has been named as Andrew Ibrahim.

A representative of the Bristol Cultural Muslim Society commented on the developments, “We hope the individual concerned is innocent and that this turns out to be a false alarm.”

It has also recently been confirmed by the police that a suspicious object was found at the scene.

He was arrested in Bristol, United Kingdom on suspicion of terrorism earlier today. There was also a controlled explosion. Parts of the city were evacuated.

Avon and Somerset police have also recently said that “It is anticipated that due to the nature of the offences believed to have been committed, work at the scene may take a number of days.”

Rod Hansen, from the police force commented on the arrest. “This has been a large scale operation and we have called upon the expertise and professionalism of staff from CID, Operational Planning, Air Support, the Hi-Tech Crime Unit and our Community Engagement Team to name but a few. It is right that I acknowledge their fine efforts also,” he said

A Wikinews reporter visited the nearest main road, Henleaze Road in the hours after the arrest, to report on the incident. It was noted that there was a significantly higher number of police vehicles in the area, compared to the usual figure.

The Wikinews reporter also noted that there were several reporters gathered around the local police station. A large police van was also noticed outside the police station.

There are few organizations in the United States that elicit a stronger emotional response than the American Civil Liberties Union, whose stated goal is “to defend and preserve the individual rights and liberties guaranteed to every person in this country by the Constitution and laws of the United States”. Those people include gays, Nazis, women seeking abortion, gun owners, SPAM mailers and drug users. People who are often not popular with various segments of the public. The ACLU’s philosophy is not that it agrees or disagrees with any of these people and the choices that they make, but that they have personal liberties that must not be trampled upon.

In Wikinews reporter David Shankbone’s interview with the President of the ACLU, Nadine Strossen, he wanted to cover some basic ground on the ACLU’s beliefs. Perhaps the area where they are most misunderstood or have their beliefs most misrepresented is their feelings about religion in the public sphere. The ACLU categorically does not want to see religion disappear from schools or in the public forum; but they do not want to see government advocacy of any particular religion. Thus, former Alabama Chief Justice Roy Moore’s placement of a ten ton monument to the Ten Commandments outside the courthouse is strenuously opposed; but “Lone Ranger of the Manger” Rita Warren’s placement of nativity scenes in public parks is vigorously defended. In the interview, Strossen talks about how certain politicians and televangelists purposefully misstate the law and the ACLU’s work in order to raise funds for their campaigns.

David Shankbone’s discussion with Strossen touches upon many of the ACLU’s hot button issues: religion, Second Amendment rights, drug liberalization, “partial-birth abortion” and whether or not George W. Bush should be impeached. It may surprise the reader that many ideas people have about the most visible of America’s civil libertarian organizations are not factually correct and that the ACLU often works closely with many of the organizations people think despise its existence.

A team of researchers from the University of Tennessee, Knoxville, has confirmed that near-Earth asteroid (29075) 1950 DA is primarily held together by van der Waals forces rather than gravity. They have shown that the rotation rate of the 1.1 km asteroid is higher than could be possible if only gravity and friction were responsible for holding it together. Cohesive forces prevent large scale shedding of material and breakup of the asteroid. Their study was published Wednesday in Nature.

The researchers found that the bulk density 1.7±0.7 g/cm³ of the asteroid is approximately two times lower than the value required for self-gravity to balance out the centrifugal forces caused by rotation. As Ben Rozitis, a planetary scientist and a co-author of the study, told Space.com: “I was expecting to find a high-density metallic asteroid, as such an asteroid wouldn’t require cohesive forces to hold itself together under its fast rotation. Instead we found the opposite! […] We knew from previous work that this asteroid was rotating faster than it should be, and we wanted to know why”.

Spectral observations of 1950DA indicated that it is either an E- or M-type asteroid in the Tholen classification. However, its low optical albedo and low radar circular polarization ratio (a very smooth surface at centimetre to decimetre scales) showed that it cannot be an E-type asteroid.

Unusually for an M-type asteroid (which are mostly metallic), 1950DA has low radar albedo. It would have been puzzling, if it was not for the Rosetta observations of 21 Lutetia, which is also an M-type asteroid with very similar low radar albedo. Researchers have used for 1950DA the same meteorite analogue which was earlier found to fit best 21 Lutetia: enstatite chondrite with grain density of 3.55 g/cm³. It allowed to calculate macro-porosity of 51±19%, indicating that 1950DA is a rubble-pile asteroid.

Taking into account thermal-infrared measurements of thermal inertia, presence of a fine-grained regolith is implied, primarily around 1950DA’s equator. Negative ambient gravity near the equator of the asteroid (48±24% of its surface) requires existence of cohesive forces to prevent loss of material. This is similar to an effect noticed between the fine grains of regolith on the Moon. Lunar regolith was found to be highly cohesive because of van der Waals forces between grains by the Apollo 17 expedition in 1974.

As Ben Rozitis explained: “We found a low-density rubble pile that traditionally would be unable to hold itself together unless cohesive forces were present. It’s exciting because we’ve provided the first evidence that cohesive forces are important for small asteroids, which had only been predicted up until now.”

The balance between cohesion and negative gravity requires small grain sizes consistent with the grain size distribution on 1950DA, and similar to that of another rubble-pile asteroid, (25143) Itokawa. Unlike Itokawa, 1950DA does not have large boulders on the surface; they may have been lost as 1950DA’s rotation accelerated due to YORP effect. This effect results in a change of the rotation rate of an asteroid (either faster or slower), and is caused when the Sun heats up an object unevenly, due to asymmetric surface topography. As the heat escapes, the rotation rate is slowly changed due to an uneven rate of cooling. The researchers find that a rubble-pile asteroid may have a high rotation rate, if it is held together by cohesive forces between the grains. But as the spin rate increases due to YORP effect, the centrifugal force may cause the rubble pile to eventually separate as it happened with P/2013 R3.

The findings may have implications for asteroid impact avoidance. A very small impulse may break one potentially hazardous object into several pieces. As Ben Rozitis said: “You’d want to avoid interacting with the asteroid directly. An alternative is to use a ‘gravity tractor,’ or a heavy spacecraft placed near the asteroid, which uses the force of gravity to pull the asteroid off course”. Bong Wie, an aerospace engineer at Iowa State University in Ames, noted: “I just hope that an asteroid on a collision course with Earth will not be spinning rapidly and it will not be a rubble-pile asteroid”.

According to Daniel Scheeres, an aerospace engineer at the University of Colorado, Boulder, understanding such cohesive forces may also be important for future asteroid mining. Ben Rozitis clarified: “Mining missions intend to visit small asteroids about 10 meters (33 feet) or less in size, as it is thought that they are predominantly solid bodies. However, cohesive forces enable such small asteroids to be rubble piles instead. A small rubble-pile asteroid would be harder to interact with and collect, as it can easily deform or break up when subject to external forces.”

The study was supported by Jet Propulsion Laboratory, California Institute of Technology and the NASA.

A major security hole was discovered in the pseudo-random number generator (PRNG) of the Debian version of OpenSSL. OpenSSL is one of the most used cryptographic software, that allows the creation of secure network connections with the protocols called SSL and TLS. It is included in many popular computer programs, like the Mozilla Firefox web browser and the Apache web server. Debian is one of the most used GNU/Linux distributions, on which are based other distributions, like Ubuntu and Knoppix. The problem affects all the Debian-based distributions that were used to create cryptographic keys since the September 17, 2006. The bug was discovered by Luciano Bello, an argentine Debian package maintainer, and was announced on May 13, 2008.

This vulnerability was caused by the removal of two lines of code from the original version of the OpenSSL library. These lines were used to gather some entropy data by the library, needed to seed the PRNG used to create private keys, on which the secure connections are based. Without this entropy, the only dynamic data used was the PID of the software. Under Linux the PID can be a number between 1 and 32,768, that is a too small range of values if used to seed the PRNG and will cause the generation of predictable numbers. Therefore any key generated can be predictable, with only 32,767 possible keys for a given architecture and key length, and the secrecy of the network connections created with those keys is fully compromised.

These lines were removed as “suggested” by two audit tools (Valgrind and Purify) used to find vulnerabilities in the software distributed by Debian. These tools warned the Debian maintainers that some data was used before its initialization, that normally can lead to a security bug, but this time it was not the case, as the OpenSSL developers wrote on March 13, 2003. Anyway this change was erroneously applied on September 17, 2006, when the OpenSSL Debian version 0.9.8c-1 was released to the public.

Even though the Debian maintainer responsible for this software released a patch to fix this bug on May 8, 2008, the impact may be severe. In fact OpenSSL is commonly used in software to protect the passwords, to offer privacy and security. Any private key created with this version of OpenSSL is weak and must be replaced, included the session keys that are created and used only temporary. This means that any data encrypted with these keys can be decrypted without a big deal, even if these keys are used (but not created) with a version of the library not affected, like the ones included in other operating systems.

For example any web server running under any operating system may use a weak key created on a vulnerable Debian-based system. Any encrypted connection (HTTPS) to this web server established by any browser can be decrypted. This may be a serious problem for sites that requires a secure connection, like banks or private web sites. Also, if some encrypted connection was recorded in the past, it can be decrypted in the same way.

Another serious problem is for the network security software, like OpenSSH and OpenVPN, that are used to encrypt the traffic to protect passwords and grant the access to an administrative console or a private network protected by firewalls. This may allows hackers to gain unwanted access to private computers, networks or data traveled over the network, even if a not affected version of OpenSSL was used.

The same behavior can be applied to any software or protocol that use SSL, like POP3S, SSMTP, FTPS, if used with a weak key. This is the case of Tor, software used to offer strong anonymity on the TCP/IP, where about 300 of 1,500-2,000 nodes used a weak key. With 15-20% of weak Tor nodes, there is a probability of 0.34-0.8% circa to build a circuit that has all tree nodes weak, resulting in a full loss of anonymity. Also the case of only one weak node begin used may facilitate some types of attack to the anonymity. The Tor hidden services, a sort of anonymous public servers, are affected too. However the issue was speedily addressed on May 14, 2008.

The same problem also interested anonymous remailers like Mixmaster and Mixminion, that use OpenSSL to create the remailer keys for the servers and the nym keys for the clients. Although currently there is no official announcement, at least two remailer changed their keys because were weak.
