Online organisations around the world are today testing Internet Protocol Version 6 (IPv6) — a new system of Internet addresses hoped to resolve the issue of the present system being at capacity. World IPv6 Day is checking everything works as planned.

The current IPv4 standard was set up in the 1980s; it gives everything on the Internet a twelve-digit address and allows for 4.3 billion combinations. With these exhausted, IPv6 is designed to increase the limit 340 undecillion — that’s 340 trillion trillion trillion.

Major websites including services run by Google, Facebook, and Yahoo! are taking part in the test, switching their content to use the new system. Facebook predicts 99.97% of users to be unaffected and Google anticipates 99.5% will not encounter problems. The remainder may encounter slow page loading.

Fiji and Australia are among the first countries to have business-hours web traffic during the test. Internet Society of Australia President Tony Hill claims more than 100 global companies are involved.

Two new records for the largest known prime number have been set, both breaking the 10 million digit threshold. On August 23, Edson Smith, a systems engineer for the Program in Computing laboratory at the University of California, Los Angeles in California, United States, confirmed the primality of the number through his work as a volunteer in the distributed computing project known as the Great Internet Mersenne Prime Search, or GIMPS. This new prime number is expressed as two to the 43,112,609th power minus one, and consists of 12,978,189 decimal digits when written out. This number qualifies GIMPS for a $100,000 award from the Electronic Frontier Foundation (EFF), offered to the first person or group to discover a prime number of 10 million digits or more. According to GIMPS’ prize agreement, $50,000 will be given to the UCLA Department of Mathematics, $25,000 will be given to charity, $20,000 will be split among previous discoverers of Mersenne primes, and GIMPS will keep the remainder for funding and other uses. Smith, who was contacted by Scientific American by phone, said that the discovery was “quite unexpected.”

Just two weeks later, on September 6, another Mersenne prime was discovered, this time by German electrical engineer Hans-Michael Elvenich, who worked for the chemical company Lanxess in Germany. This number is expressed as two to the 37,156,667th power minus one, and is 11,185,272 digits long. However, since this prime number was discovered later than the one found on August 23, it does not qualify for the EFF prize. Elvenich said that it was a “finally a great success” after having participated in GIMPS for four years.

A prime number is a positive integer that can be evenly divided only by 1 and itself. For example, 2, 3 and 11 are prime numbers. 21 is not a prime number because it is a product of 3 and 7. These types of prime numbers are called Mersenne primes, which can be expressed as one less than a power of two. Mersenne primes are rare, and only 46 are known up to now. The first few Mersenne primes are 3, 7, 31, 127 and 8191.

These numbers took a total of several weeks to verify, using different software and hardware. Each number was independently checked by several members of GIMPS’ verification team, using 16-core systems of different configurations. The two primes were announced by GIMPS on September 16. Before these two discoveries, the two previously largest known prime numbers were discovered by UCMO professors Curtis Cooper and Steven Boone in Missouri, United States, and their record lasted almost three years. Historically, prime numbers discovered by GIMPS are larger than the one previously found. The only other exception was when the 29th Mersenne prime was discovered after the 30th and 31st were found.

Founded by M.I.T. graduate George Woltman in 1996, GIMPS has found 12 Mersenne primes, or about one per year on average. Volunteers who wish to help find primes can download a program called Prime95, which runs in the background.

Smaller prime numbers, such as those with a few hundred digits, are often used in cryptography. The recently discovered prime numbers are too large to have much practical value, although it is believed by some that such prime numbers may still have undiscovered uses. However, mathematics enthusiasts often seek them for fun, and the GIMPS community is already looking forward to finding a 100 million digit prime that will qualify for a $150,000 prize from the EFF.

On the corner of Golden Gate Ave. and Jones St. in the Tenderloin, San Francisco, right next to the Civic Center you can see a throng of low-income and homeless people lining up outside of St. Anthony’s Dining Room hall which opens up it’s doors everyday at 11:30 a.m. Volunteers dressed in St. Anthony Foundation shirts help keep the lines moving as hundreds of homeless and low income people shuffle their way towards the dining hall underneath the watchful eyes of a small statue of St. Francis of Assisi.

“There’s a lot of people who go hungry out here and it ain’t right.” says Jimmy Scott, a slightly brawny 44-year-old black man who has been living homeless in San Francisco for the past three years. “There are families out here with kids and everything and they have to walk around all night just to stay awake so they don’t get hurt or killed…Right here in the U.S. this is going on…it ain’t right.”

The dining hall, which has been open for the past 54 years, is owned by the St. Anthony Foundation which helps low income and homeless people and families in the Civic Center, Tenderloin, and SOMA areas with clothing, shelter, food, drug rehabilitation, and many other services. St. Anthony’s administrative offices are found at 121 Golden Gate Ave. with the majority of the foundation’s buildings on Golden Gate Ave. and Jones St.

“We are right in the heart of the homeless population of San Francisco,” says Barry Stenger, 55, who’s been working for the St. Anthony Foundation for one year, and is the Director of Development and Communications, “and people are pushed here because of the economic forces of San Francisco because it’s hard to be upper middle class in San Francisco.”

According to the San Francisco Chamber of Commerce, “San Francisco’s cost of living remains one of the highest in the country” with the average household income in San Francisco being around $76,400 and the average price of housing being $543,000. Average household income for the United States in 2002, according to the U.S. Census Bureau, was $42,409 and the average price of housing for the United States according to the National Association of Realtors was $185,200 in 2004.

“We served our 32 millionth meal on Tuesday,” said Stenger, “and we serve 2,500 meals a day. Some of our people who work here actually get served [food] here because they spend all their money towards rent and medical costs.”

The St. Anthony Foundation was started by Fr. Alfred Boeddeker in 1950 one year after Fr. Boeddeker became pastor of St. Boniface church on Golden Gate St. where he was baptized as a child. During his lifetime, according to the foundation’s website, he was referred to as the “Patron St. of the Tenderloin” and had Boeddeker park named after him because of his, and his foundation’s, achievements with helping out the homeless and low income community.

“[St. Anthony’s] is a good thing,” said Jimmy Scott, “they provide a good service and they feed people and they clothe them and provide furniture when you get housing and give you groceries when you have AIDS. It’s a good little organization.”

“Our dining room is open 365 days a year.” Said Stenger. “Our other facilities are open seven days a week. We have a residence for senior women and our [free medical] clinic is open five days a week and we also have a furniture and clothing store. We have 12 programs all together.”

Some of those programs are the Father Alfred Center which provides 61 men two programs for getting out of drug and alcohol abuse, the Employment Program/Learning Center which helps participants in educational and employment opportunities and provides each one with a personal staff advisor, and a Senior Outreach and Support Services center which states its mission is to “promote independence, self determination, and alleviate isolation” for seniors who are 60 and older.

A few homeless people who were interviewed complained that St. Anthony’s had some staff who were rude and that they were kicked out of the dining hall; other homeless within the area refuted those claims saying St. Anthony’s has nice staff and only kicks people out who cause trouble.

“It’s a good place and good people. Everybody is so kind and so respectful and everything is under control.” Said John Henderson, a tall and skinny 57-year-old homeless black man who has only been living in San Francisco for close to two months because he recently moved there from Phoenix, Arizona. “It’s pretty cool because they’re under control because yesterday I saw at Glide [Memorial Church which also has services for the poor and low income] and they were handing out food boxes and people were just rushing in and the woman in charge there was freaking out and so she just sat down. That would never happen at St. Anthony’s.”

“And they clean too!” Henderson said laughing with a grin on his face referring to the fact that there are no drugs allowed in the premises. “Not that Glide ain’t clean if you know what I mean.”

“We [also] have a whole division that deals with justice education and advocacy to change the system that brings people to our doorstep.” Said Stenger. “We hear a lot of appreciation from the people we serve. We get a lot of testimony from our clients who have become clean and sober. Sometimes we have to push them a little to get them out the door because they love the [foundation] so much because it has changed their lives.”

United States Supreme Court Associate Justice Ruth Bader Ginsburg, 75, has undergone surgery for early pancreatic cancer today. The disease was spotted during a routine check-up. She is likely to be hospitalised for ten days.

“Justice Ginsburg had no symptoms prior to the incidental discovery of the lesion during a routine annual checkup in late January at the National Institutes of Health in Bethesda, Maryland,” the Supreme Court announced.

Ginsburg underwent sugery and had chemotherapy for colorectal cancer in 1999; her mother and husband also suffered from cancer.

She was appointed to the Supreme Court by President Bill Clinton in 1993, and is considered to be on the liberal wing of the nine-member court.

A spokesman for President Barack Obama said that Obama’s thoughts and prayers are with Ginsburg.

According to the American Cancer Society, the one-year survival rate for pancreatic cancer is 24%, and the five-year survival rate is 5%.

Ian Narev, the CEO of the Commonwealth Bank of Australia, this morning “unreservedly” apologised to clients who lost money in a scandal involving the bank’s financial planning services arm.

Last week, a Senate enquiry found financial advisers from the Commonwealth Bank had made high-risk investments of clients’ money without the clients’ permission, resulting in hundreds of millions of dollars lost. The Senate enquiry called for a Royal Commission into the bank, and the Australian Securities and Investments Commission (ASIC).

Mr Narev stated the bank’s performance in providing financial advice was “unacceptable”, and the bank was launching a scheme to compensate clients who lost money due to the planners’ actions.

In a statement Mr Narev said, “Poor advice provided by some of our advisers between 2003 and 2012 caused financial loss and distress and I am truly sorry for that. […] There have been changes in management, structure and culture. We have also invested in new systems, implemented new processes, enhanced adviser supervision and improved training.”

An investigation by Fairfax Media instigated the Senate inquiry into the Commonwealth Bank’s financial planning division and ASIC.

Whistleblower Jeff Morris, who reported the misconduct of the bank to ASIC six years ago, said in an article for The Sydney Morning Herald that neither the bank nor ASIC should be in control of the compensation program.
