Twitter hack to hinder e-commerce service uptake

The recent hack on Twitter which affected 250,000 users will have left subscribers uneasy over linking their microblogging accounts to their American Express credit card accounts to conduct e-commerce activities.

The saving grace would be American Express' efforts in beefing up its online transaction security these past years, which should convince some users that the e-commerce tie-up between the two companies remains a viable service.

Last Monday, Twitter announced its e-commerce partnership with American Express. Credit card holders who link their bank accounts with their Twitter handles will be able to trigger a purchase of products such as jewelry or gift cards by posting a tweet.

Twitter was the victim of a successful breach on its systemsearlier this month, however. It said: "[Our] investigation has thus far indicated that the attackers may have had access to limited user information--user names, e-mail addresses, session tokens and encrypted/salted versions of passwords--for approximately 250,000 users."

Commenting on these developments, Jonathan Andresen, director of product marketing at Blue Coat Asia-Pacific, said the hacking attack on the microblog site may affect the confidence of potential users of the e-commerce service.

He said it is very important for companies to protect their sites from online attacks as frequent breaches may damage a company's brand. "This is similar to every other online service such as banking. If they do not ensure it is secure, people will have no confidence to use it," Andresen noted.

Eric Chiu, president and founder of HyTrust, agreed. He said: "It's one thing to have someone use your credentials to hijack your Twitter account. It is an entirely different thing if they can charge purchases to your credit card."

Twitter user Jacky Chua told ZDNet Asia she would be "worried" about signing up for the Twitter-American Express service following news of the successful attack on the social media platform.

"I'm not sure if I'm willing to put my credit card information there," Chua said.

Another subscriber, Melvin Lum, said he was planning to limit his usage of Twitter to "prevent more information from getting stolen. "I'm already tweeting less and may close my account in the near future. I'm not even thinking of putting my credit card information there," he added.

American Express to save the day
However, Kendrick Sands, consumer finance company analyst at Euromonitor, disagreed. He said one of American Express' distinguishing factors is its customer service and responsiveness is reimbursing companies for fraudulent charges. For this reason, customers of the payment service provider are less likely to be worried about the service partnership with Twitter, he said.

Furthermore, American Express has invested millions in its online processing capabilities and security over the last few years, and will be prepared for the challenges--security or otherwise--presented by the increased online transactions, said Sands.

Nadia Mohammad, too, expressed confidence in the e-commerce partnership. The Twitter and American Express user said the online attack on Twitter would not deter her from signing up for the service because she "believed in American Express" and payment companies have stronger security measures than social networks to protect their customers.

"Twitter would've also stepped up measures to improve its security after the incident, so I don't see why I should be afraid," said Nadia.

Moving forward, both companies must increase their efforts to protect cardholder and credential information, Chiu stressed. Linking credit card information to a social media site will require the latter to put in place much higher levels of security than it does today, he added.

This will also improve user perception of the microblogging site and bring in more users to join the e-commerce partnership, Chiu explained, adding that Twitter will become an even greater target with the American Express partnership.

With millions of users to monitor, Twitter and American Express can also consider using a real-time Web security cloud service to ensure instantaneous feedback is available by analyzing Web content and blocking threats, Andresen advised.

Twitter and American Express did not respond in time to comment on their security efforts to safeguard customers' online transactions and personal information.

Pope asks continued prayers in these 'unusual' days for church


People watch from St. Peter's Square as Pope Benedict XVI leads the Angelus from the window of his apartment at the Vatican Feb. 17. The pope is resigning Feb. 28. (CNS/Reuters)
By Cindy Wooden
Catholic News Service

VATICAN CITY (CNS) -- Calling this an unusual time for him and for the church -- but not specifically mentioning his resignation -- Pope Benedict XVI thanked people for their affection and asked them to continue their prayers.

A roar of applause rose up from more than 50,000 people gathered in St. Peter's Square Feb. 17 as Pope Benedict came to his studio window to lead the Angelus prayer.

People came to St. Peter's in larger numbers than normal for a Sunday Angelus because it was the first completely public, no-tickets-needed event since the pope announced Feb. 11 that he would be stepping down Feb. 28.

As he does every week, he greeted groups of pilgrims in their native tongues. Addressing Spanish speakers, he said, "My heartfelt thanks ... for your prayers and affection in these days. Continue to pray for me and the next pope."

And he told Polish speakers, "Thank you for your prayerful support and spiritual closeness in these days that are so unusual for the church and for me."

Before leading the Angelus prayer, Pope Benedict commented on the beginning of Lent and the day's Gospel reading about the temptation of Jesus.

He said Lent is a time for Catholics to renew their spiritual lives and turn to God, "renouncing pride and selfishness to live in love."

Making God the center of one's life, he said, requires "spiritual battle" because the devil doesn't want people to be holy and "tries to detour us from the path toward God."

The Gospel account of the temptation of Jesus in the desert, he said, shows just how "subtle" the devil can be: he does not try to trick Jesus directly into evil, but tempts him with "a false good."

When power or material goods, even basic necessities, become the most important priorities, "God becomes secondary," the pope said. "In the final analysis, faith is at stake with temptations because God is at stake. In the decisive moments of our lives, we face a juncture: do we want to follow the ego or God, individual interests or the one who is truly good?"

The good news, the pope said, is that Jesus has defeated the devil for us, "therefore, we are not afraid to take up the battle against evil; what is important is that we do so with him, with Christ, the victor."

For many Roman families, joining the pope for the recitation of the Angelus is a normal part of a Sunday or holiday stroll, and Feb. 17 they were joined by Gianni Alemanno, mayor of Rome, and members of the city council.

With large crowds expected, officers from a variety of Italian and Rome police forces, as well as paramedics and even garbage collectors had deployed along the broad avenue leading to St. Peter's Square and along the square's perimeter by 10 a.m.

An hour before the Angelus, thousands of people were already in the square. The young staked out places by sitting on the cold cobblestones. Others previewed their banners for the press, including some that said: "You are Peter. Stay" and "Thank you, Holy Father. We love you very much."

Pope Benedict ended his remarks by asking for special prayers for himself and his top aides in the Roman Curia as they were about to begin their annual Lenten retreat that evening.

Apple iPad Ads Highlight Wealth of Applications

The latest ads seem to be a bit of a departure from Apple?s minimalist approach, featuring more upbeat music and a faster pace.

One of the savviest technology companies on the planet released two television commercials aimed at convincing consumers to pick up its iPad and iPad mini tablets. The two commercials, titled ?Alive? and ?Together?, highlight the software operating system and ecosystem of applications that help make Apple?s hardware so desirable. The fast-paced ads, which are accompanied by a bouncy musical score, showcase the various capabilities of the tablet. Like everything else with Apple, the company?s advertising strategy is always closely scrutinized, and the latest ads seem to be a bit of a departure from Apple?s minimalist approach. In addition to the new TV spots, Apple also debuted a new line of print advertisements also aimed at highlighting the wealth of applications designed specifically for the tablet. Apple is facing increased competition from other tablet vendors like Samsung and Amazon, but remains the clear market leader. Apple's tablet sales were driven by strong demand for the iPad Mini. With a recent Canalys report estimating that the 7-inch device made up more than half of Apple's total tablet shipments, owing to an attractive price point (a debatable point of analysis) and compact design, which the firm said has led to "significant cannibalization" in the iPad range and the wider PC market. The 2012 holiday quarter also marked the first time Apple has not controlled half the tablet market; the company's share stood at 49 percent at the end of 2012, despite record shipments. Including iPad sales, worldwide PC shipments increased 12 percent year-on-year in the fourth-quarter to reach 134 million units. "Apple timed the launch of the iPad Mini well,' Canalys research analyst Pin-Chen Tang said in a statement. "Its success proves there is a clear demand for pads with smaller screens at a more affordable price. Without the launch, Apple would surely have lost more ground to its competitors." The company recently gave its MacBook Pro with Retina display notebook a refresh, sporting updated processors and lower starting prices: The entry-level 13-inch MacBook Pro with Retina display now starts at $1,499 for 128GB of flash storage, and $1,699 for a new 2.6 GHz processor and 256GB of flash storage. Apple also upgraded the 15-inch MacBook Pro with Retina display, which now features a faster 2.4 GHz quad-core processor, and the flagship 15-inch notebook comes with a new 2.7 GHz quad-core processor and 16GB of memory. Apple also announced that the 13-inch MacBook Air with 256GB of storage has a new lower price of $1,399. All models are available through the company?s online store, retail stores and authorized resellers.

Clinical South Africa seal series win

CAPE TOWN | Sun Feb 17, 2013 5:42pm GMT

CAPE TOWN (Reuters) - South Africa showed why they are the number one test team in the world with a clinical performance on day four of the second test against Pakistan to clinch the series with a four-wicket victory on Sunday.

Excellent bowling in the morning session was backed up with steady batting under the hot sun as they chased down a victory target of 182.

South Africa now lead the three-match series 2-0 with one match remaining in Centurion starting on February 22.

Hashim Amla anchored their chase with an enterprising 58 from 96 balls that drained the belief from the Pakistan bowlers.

The tourists picked up some late wickets to allow spinner Saeed Ajmal to record match figures of 10 for 147, but by then the game was lost.

Starting their innings 30 minutes after lunch having bowled Pakistan out for 169 in their second innings, the home side lost the early wicket of Alviro Petersen lbw to Umar Gul for one.

Graeme Smith (29) then became Ajmal's first victim of the innings when he was also trapped in front going on the sweep, the second time in the test he has been out in that fashion.

Jacques Kallis hit a brisk 21 before being dismissed lbw by Ajmal.

Amla was magnificent as he steered the ball all round the ground, but was bowled as he had an uncharacteristic wild swing at an Ajmal delivery, bringing an end to his fine knock.

AB de Villiers (36) also played a reckless flashing cut that was caught by wicketkeeper Sarfraz Ahmed off Tanvir Ahmed to give the bowler his only wicket of the test.

Faf du Plessis (15) was lbw to Ajmal with two runs needed, but Dean Elgar (11 not out) smashed the winning runs.

Perhaps fittingly, he was at the crease at the time with man of the match Robin Peterson (1 not out), who had changed the course of the match with his 84 on Saturday and fine bowling on the fourth morning.

FIRST BREAKTHROUGH

The victory was set up by South Africa taking seven Pakistan wickets for the addition of 69 runs.

The tourists resumed on 100 for three, but it was not long before the hosts had their first breakthrough.

Misbah-ul-Haq attempted a poorly executed sweep off Peterson and sent a top-edge flying to Graeme Smith at leg slip, the batsman departing for a patient 44.

Asad Shafiq (19) was next to go, unlucky to see the ball bounce onto the stumps after it looped up following his back-foot defensive shot off Vernon Philander.

Then came a collapse that rocked Pakistan as they lost three wickets in as many balls.

Sarfraz Ahmed (five) left a Peterson delivery that turned out of the leg-side rough and cannoned into his stumps.

It was the last ball of the spinner's over, with Philander taking up the attack from the other end and getting wickets with his first two balls.

Ali had reached his 14th test half-century when he edged to wicketkeeper AB de Villiers for 65, and Gul lasted one delivery as he was brilliantly caught by a diving Petersen at third slip.

Ajmal (four) was bowled around his legs by Peterson and Mohammad Irfan (two) was the last wicket down as he fended a Dale Steyn bouncer to Petersen in the slips.

Philander ended with match figures of nine for 99.

Irish football team's success helped rekindle Staten Island fundraiser

INSOUT17.jpg At the rescheduled Notre Dame Club of Staten Island/Knights of Columbus, Manresa Council No. 2147 event on Jan. 7 are, kneeling from the left, students Danielle Lopez and Joshua Lopez. Standing, holding the flag, are students Derek Halligan and Miguel Lopez. Standing behind the flag are Monsignor James Dorney, Principal Margaret Annunziata and Tara Alleyne-Lopez. Standing, back row, are Joe Delaney, the Rev. Michael Cichon, Ann Broderick and Mike McHugh. ? STATEN ISLAND, N.Y. ? On Saturday morning, Nov. 3, just five days after Hurricane Sandy devastated these shores, Joe Delaney of the University of Notre Dame Club of Staten Island and Mike McHugh of the Knights of Columbus, Manresa Council No. 2147, surveyed the destruction of Manresa Council Hall, located on Cedar Grove Avenue in New Dorp Beach.

As they viewed the devastation of homes and property in the area all around Manresa Council Hall, they thought that their Notre Dame-Pittsburgh fundraiser for St. Peter-St. Paul School, originally scheduled that very Saturday at 3 p.m. and now canceled, would never be rescheduled.

For the past 11 years, the Notre Dame Club and Manresa Council have combined efforts to raise funds to support Catholic education at St. Peter-St. Paul School in New Brighton. In fact, since 2002, the two groups had raised a total of $45,000 for the school.

Joe goes on to explain that the Notre Dame-Pittsburgh football game on Nov. 3 ? won by The Fighting Irish 29-26 in miraculous, come-from-behind triple overtime fashion, a win that continued Notre Dame?s unbeaten season ? allowed both men to dream big and save the fundraiser.

If the Irish finished the 2012 season undefeated, they thought, that might allow them to re-schedule the fundraiser and build the event around a Notre Dame BCS Championship Bowl game on Jan. 7.

?The beneficiaries of a re-scheduled gamewatch/fundraiser would still be St. Peter-St. Paul, but would now include the recently established Manresa Council Re-Building Fund,? Joe added.

Unbeaten Notre Dame did end up playing Alabama for the BCS title on Jan. 7. Almost 200 people showed up at The Hillside Swim Club, Bulls Head, to watch the game and support the fundraiser.

Through a series of raffles and prize drawings, a final combined total of $10,000 was raised to help St. Peter-St. Paul School and The Manresa Building Fund. Proceeds were split evenly between the two.

Joe points out that several Staten Island businesses supported the fundraiser by donating food and services. Special thanks to Jimmy Maxx Pizza?s Jimmy McBratney; Joe Gustivino from Pier 76 Restaurant for a large donation of food, and Ed Thatcher for donating hot dogs, rolls, a sheet cake and milk.

Although Notre Dame lost the game to Alabama, 42-14, Joe states:

?The real winners of the evening?s game were the students of St. Peter-St. Paul School and the K of C Manresa Council, who will re-build their Council Hall.?

Assisting Mike and Joe with the planning and organization of the fundraiser was Notre Dame Club members Bob Griswold, Ann Mulchay, Christine Thomson and Mike Waters.

Assisting from Manresa Council was Judith McHugh, Bob and Nancy Bauer, Andrew Diaz and Jim Neese.

In closing, Joe notes: ?Hurricane Sandy did, indeed, devastate Staten Island. However, Sandy could not defeat the spirit of the Staten Islanders, like the members of the Notre Dame Club of Staten Island and the Manresa Council No. 2174.

?Neither of these two groups would allow a tragedy like Sandy to prevent them from helping the children of St. Peter-St. Paul and restoring a community landmark in New Dorp Beach.?

CELEBRATIONS

The happiest of birthdays today to Anne Lombardi; Allison Warheit; Stu Germain; Johnny Balletto; Carmela (Millie) Lupo, who turns 89, so say her daughters Marilyn Wickert and Patty LaGrotta, and Lisa Ann Paoluccio.

Happy 45th wedding anniversary to Pat and Bob Dalrymple and to Gerri and Marty Collins, friends who were married on the same day in different churches.

Tomorrow is birthday time for Narcy F. Santos, Phyllis Mehl, Hilton Flores, Maria Pacifico, Kelsey Bougadis, Erik Andersen, Amy Andriulli-Guarcello, Kathryn Carse and Jenna Camren Hershkowitz, who?ll celebrate her 8th birthday with a party with her gal pals followed by a party with family members.

Forget about leprechauns, engineers are catching rainbows

Feb. 15, 2013 ? University at Buffalo engineers have created a more efficient way to catch rainbows, an advancement in photonics that could lead to technological breakthroughs in solar energy, stealth technology and other areas of research.

Qiaoqiang Gan, PhD, an assistant professor of electrical engineering at UB, and a team of graduate students described their work in a paper called "Rainbow Trapping in Hyperbolic Metamaterial Waveguide," published Feb. 13 in the online journal Scientific Reports.

They developed a "hyperbolic metamaterial waveguide," which is essentially an advanced microchip made of alternate ultra-thin films of metal and semiconductors and/or insulators. The waveguide halts and ultimately absorbs each frequency of light, at slightly different places in a vertical direction, to catch a "rainbow" of wavelengths.

Gan is a researcher within UB's new Center of Excellence in Materials Informatics.

"Electromagnetic absorbers have been studied for many years, especially for military radar systems," Gan said. "Right now, researchers are developing compact light absorbers based on optically thick semiconductors or carbon nanotubes. However, it is still challenging to realize the perfect absorber in ultra-thin films with tunable absorption band.

"We are developing ultra-thin films that will slow the light and therefore allow much more efficient absorption, which will address the long existing challenge."

Light is made of photons that, because they move extremely fast (i.e., at the speed of light), are difficult to tame. In their initial attempts to slow light, researchers relied upon cryogenic gases. But because cryogenic gases are very cold -- roughly 240 degrees below zero Fahrenheit -- they are difficult to work with outside a laboratory.

Before joining UB, Gan helped pioneer a way to slow light without cryogenic gases. He and other researchers at Lehigh University made nano-scale-sized grooves in metallic surfaces at different depths, a process that altered the optical properties of the metal. While the grooves worked, they had limitations. For example, the energy of the incident light cannot be transferred onto the metal surface efficiently, which hampered its use for practical applications, Gan said.

The hyperbolic metamaterial waveguide solves that problem because it is a large area of patterned film that can collect the incident light efficiently. It is referred to as an artificial medium with subwavelength features whose frequency surface is hyperboloid, which allows it to capture a wide range of wavelengths in different frequencies including visible, near-infrared, mid-infrared, terahertz and microwaves.

It could lead to advancements in an array of fields.

For example, in electronics there is a phenomenon known as crosstalk, in which a signal transmitted on one circuit or channel creates an undesired effect in another circuit or channel. The on-chip absorber could potentially prevent this.

The on-chip absorber may also be applied to solar panels and other energy-harvesting devices. It could be especially useful in mid-infrared spectral regions as thermal absorber for devices that recycle heat after sundown, Gan said.

Technology such as the Stealth bomber involves materials that make planes, ships and other devices invisible to radar, infrared, sonar and other detection methods. Because the on-chip absorber has the potential to absorb different wavelengths at a multitude of frequencies, it could be useful as a stealth coating material.

Additional authors of the paper include Haifeng Hu, Dengxin Ji, Xie Zeng and Kai Liu, all PhD candidates in UB's Department of Electrical Engineering. The work was sponsored by the National Science Foundation and UB's electrical engineering department.
