Oracle Is Quick to Recover

Oracle Corp. felt the recession effect later than most companies in the technology sector. But the software maker does not have to wait as long to recover.

The producer of database and business software posted a 17% raise in revenue for its fiscal third quarter, marking its second successive quarter of growth after a string of declines in the recession.

While Oracle's profit fell 11% in the quarter because of charges related to its achievement of computer-server maker Sun Microsystems Inc., which closed in late January, the company forecast strong growth. Oracle projected total revenue for the current quarter would jump 31% to 36% from a year earlier.

"Our channel is very strong in both software and hardware," said Safra Catz, Oracle's co-president.

The demand is coming from clients like Matthew Leeds, vice president of operations at digital media company Gracenote, a division of Sony Corp. Mr. Leeds thought he plans to buy software from Oracle and hardware from Sun before the end of the month. "I have the budget so I'm placing an order," he said.

Oil giants propose limiting federal lapse of fracturing

BP, ConocoPhillips and Shell Oil Co. have provided Senate lawmakers with speech to include in a pending climate change bill that essentially would block federal oversight of hydraulic fracturing, a skill that's key to the current natural gas drilling boom.

The companies arranged the document, according to sources familiar with it, at the appeal of the Senate team that is drafting climate change law, which includes Sens. John Kerry, D-Mass., Lindsey Graham, and R-S.C., and Joseph Lieberman, I-Conn.
If integrated into the climate change law, it would keep the Environmental Protection Agency from striking regulations on fracturing, which is now regulated at the state level.

The document recommends that states adopt standards for disclosing the contents of hydraulic fracturing chemicals “to health professionals or state agencies” in order to protect health or environmental safety but maintain “the confidentiality of trade secret information” in the fluids.

Detecting bogus wine vintages: It's an (atomic) blast

Two decades of atomic bomb testing in the atmosphere are yielding an unexpected bonus for consumers, scientists reported here at the 239th National Meeting of the American Chemical Society (ACS). It's a new test to decide whether that Bordeaux or burgundy is from a fine vintage year and commands premium price or actually is a counterfeit vine ordinaries or cheap plonk worth much less.

Graham Jones, Ph.D., who headed the research, said that misrepresenting the vintage the year the wine was made is an ongoing problem. He is with the University of Adelaide, Australia. Some years bring perfect rising conditions for vineyards in a country or region of a country and the grapes produce excellent wines that command premium prices. In other years, bad weather, such as heavy late-season rains that bloat grapes with water or long hot, dry spells at harvest, means poor quality wines. Some wine experts estimate that up to 5 percent of the fine wine sold today is fake.

Catholic Health Association Congratulates Nation's Leaders for Enacting Notable Health Reform

The Catholic Health Association applauds the U.S. House of Representatives and President Obama for enacting health care reform legislation that will bring security and health to millions of American families. The reform law will save and improve lives across our country. It represents great progress in the long effort to make health care available and affordable to everyone in the United States.

We call upon the U.S. Senate to move quickly to enact the accompanying correction legislation in order that the full benefits of reform become a reality.

While not perfect, the reform law notably expands coverage, especially to low-income and weak populations, and is a tremendous step toward protecting human pride and promoting the common good. The law will prevent insurance companies from denying policies to those with pre-existing conditions protect families from bankruptcy due to medical expenses help small businesses provide insurance for their workers improve Medicare drug benefit coverage by closing the doughnut hole and significantly cut the federal deficit. Most importantly, 32 million people who were previously uninsured will be able to obtain meaningful coverage at an affordable price.

New TSA consultant fights for Muslim rights

Since the Sept. 11, 2001, terrorist attacks, Nawar Shora, the legal director for the Arab American Anti-Discrimination Committee, has sparred with the federal government over what he saw as security abuses against minorities. Now, he is joining the Transportation Security Administration as a senior consultant for its office of civil rights and liberties.

Shora, 33, said the move next month to the Department of Homeland Security will back up what he has been telling interns for a decade, urging them to enter federal service.

"I'm finally practicing what I preach," said Shora, a self-described "Arab country boy" who was born in Syria and raised in Huntington, W.Va.

Airlines expand admittance to mobile boarding passes

Paper boarding passes could become an scarce species as more airlines offer boarding passes via mobile devices, which allow you to download a bar code to your Web-enabled phone or other device in place of printing a piece of paper.

United Airlines began offering the service last week in 13 airports. The airline expects to expand the service to 30 other airports by summer, according to a spokeswoman.

"It gives customers added convenience," said Sarah Massier, a United spokeswoman.
American Airlines last week added 19 new airports to the eight where it already had offered the service.

Hosted Drupal CMS intended for midyear

Acquia hopes to make a hosted description of its Drupal open-source content management system extensively available in about three months, the company's CTO said Wednesday.

The service, called Drupal Garden, is in beta testing now with a "couple of thousand" users, said Dries Buytaert, who created Drupal and cofounded Acquia to build a commercial business around it. The service will be based on Drupal 7, an upgrade to the CMS software that will be released at about the same time, Buytaert said at the Open Source Business Conference in San Francisco on Wednesday.

Drupal is a software platform for publishing Web sites and managing text, images and other content on those sites. It has been used by folks to publish blogs and by larger organizations, including the White House and NASA, to run their Web sites.

Michelle Obama talks anti-corpulence to food giants

WASHINGTON | Michelle Obama is urging the nation’s largest food companies to speed up efforts to make healthier foods and reduce marketing of unhealthy foods to children.

Obama asked the companies, gathered at a meeting of the Grocery Manufacturers Association on Tuesday, to “step it up” and put less fat, salt and sugar in foods.

“We need you not to just twist around the edges but totally rethink the products you are offering, the information that you provide about these products, and how you market those products to our children,” she said.

US consulate employees killed in Mexico drug wars


The drug wars in Mexico took a menacing turn over the weekend when a US consulate employee and her husband were killed as they left a children's birthday party in Ciudad Juarez, Mexico's most violent city. Only minutes earlier gunmen also killed the Mexican husband of another member of the consular staff and wounded his two children.

While a number of US citizens have been killed in Mexico's increasingly bloody drug wars between rival cartels, it is the first time an American government employee has been killed.

President Barack Obama has expressed outrage over the killings, and Mexican President Felipe Calderon promised a swift investigation.

American Airlines facing $787,500 in protection fines from FAA

The Federal Aviation Administration proposed fines of $787,500 against American Airlines Inc. on Friday for three cases involving improper maintenance.

American said it had seen the FAA's findings and plans to meet with FAA officials after it reviews them.

"American Airlines is very proud of our safety record and our employees' commitment to safety every day," spokesman Tim Smith said. "Safety is fundamental to the American Airlines culture and to our success."

The biggest penalty, $625,000, was for allowing a McDonnell Douglas MD-80 to fly even though the aircraft had problems with one of its two central air data computers, the FAA said.

IBM hopes to make mobile devices more accessible


IBM is embarking on a research project to design mobile gadgets that are easier to use for people who have disabilities or aren't fully cultured.
As part of the project, announced Wednesday, Big Blue will collaborate with India's National Institute of Design and the University of Tokyo's Research Center for Advanced Science and Technology.

The goal is to develop a common interface for mobile devices that will make them easier to use. As digital information becomes more vital, IBM said, it believes the Internet needs to be more reachable to a wider range of people, including those who are illiterate, blind, deaf, and elderly, and those in developing countries.


"Through this collaborative research proposal, we will uncover real information convenience requirements and issues that the elderly and people in developing economies are facing today," Chieko Asakawa, an IBM Fellow and chief technology officer of IBM's accessibility research, said in a statement. "By focusing on mobile devices, which have a tremendous potential to empower them, we believe the findings will help us offer reasonable services to a large population, who are still deprived of access to key information sources."

Lost in Time, Letters Confine American Grief for a President

Days after President John F. Kennedy was killed, Dr. Ira Seiler sat at his desk and wrote a letter of concern to his widow, Jacqueline Kennedy.

“Today, on Thanksgiving, I wholeheartedly sense his death for it was just three years ago today that I forced my breath into the lungs of his newly born son,” Dr. Seiler wrote. John F. Kennedy Jr. was born premature, Dr. Seiler, a pediatric resident, said he placed a tube in the baby’s trachea and breathed air into his lungs.

“I met your husband only once after this but the part I played in saving his son’s life gave me a feeling of deep closeness to your husband,” Dr. Seiler wrote. He added “I only wish I had been able to give my life in place of that of your husband. He had so much to offer.”

American falls to Lehigh, 79-57, in Patriot League men's basketball semifinals

Jeff Jones set the outline minutes after fourth-seeded American's 79-57 loss at top-seeded Lehigh in the Patriot League semifinals on Sunday when the Eagles coach told his team to enjoy the upcoming break from the season's conclusion, but understand what awaits this off season.
"In all of my years as a head coach," said Jones, who coached eight years at Virginia and has been at American for 10, "this will be by far the hardest off season of any team."
Jones said the players must "face adversity" and "grow up physically and mentally."

Skype in train:America

For years, rail travel in North especiallyAmerica has seemed more like sea travel attractive, but not a vital part of the useful. However, in Europe and Asia, trains important way people get around. They’re fast and reliable, but most for the business traveler, you don’t have to switch off your phone when the train pulls out of the station. And increasingly, you don’t have to log off Face book either.

Almost a best Olympics for North America: McCollum's Column

The Winter Olympics ended perfectly for those in North America.
The last bureaucrat event was one of the greatest and most exciting Olympic ice hockey games ever played when Canada won the gold medal it had to win with the 2-1 sudden-death victory over the Americans.U.S. won most medals. Canada won most gold medals.
The Russians, who went home humiliated in hockey and failed to win a figure skating gold, went home to what we expect to be a rigorous training program or else (Siberia has a year-round winter climate) when it hosts in four years.

At the closing ceremony, the Canadians ran out just about every icon entertainer and every classic symbol of the country and found a way to work parts of “Oh Canada” (one of the best as national anthems) in almost all segments.

Tsunami warning lifted in much of south Pacific region

The Hawaii-based Pacific Tsunami Warning Center on Sunday canceled its tsunami warning for many countries in the Pacific region.

The center's warning has been lifted in French Polynesia, the Cook Islands, Kiribati, Tonga, American Samoa, Tokelau, Fiji, Hawaii the Marshall Islands, Tuvalu, Vanuatu, New Caledonia, Solomon Islands, Nauru, Papua New Guinea, the Pitcairn Islands, Niue, Guam, the Northern Marianas, Pohnpei, Chuuk and Yap.

The warning, issued after a magnitude 8.8 earthquake struck Chile, sparked evacuations in some countries but many people have now been told they can return home.

French Polynesia appeared to have suffered the worst effects of the tsunami with the Marquesas islands in the north of French Polynesia experiencing waves up to four meters high, Radio New Zealand International reported. There are no reports of casualties or major damage. The measurement for Tahiti is 40 cm.

Democrats Are Listening to the American People Opinion

On Thursday, I sat down with President Obama and my congressional colleagues from both parties to try to find a way out of the health care crisis looming our families and businesses. It was a time to face facts none of us can deny that insurance premium doubled more than last decade, with no sign of stopping that most of our smallest businesses can't afford to cover their employees anymore that America pays more per person for health care than any other mechanized country in the world, without seeing better health.

Those are some of the reasons Democrats have worked so hard to pass a centrist health reform bill, many of whose provisions are similar to those endorsed by former Republican Senate leaders Bob Dole and Howard Baker. At today's summit, we also discussed the numerous bipartisan areas of agreement that already exist and are already in the health care bill. I believe in bipartisan conciliation but Senate Minority Leader John Boehner's recent AOL News op-ed piece was more about political talking points than common solutions. It deserves a line by line rebuttal.

"Americans want Washington to scrap this job-killing government takeover of health care and start over."

It's really the growing cost of health care that's killing jobs. A study from economists at USC and Harvard shows that passing health insurance reform would create 4 million more jobs over the next decade.

Travel Alert for Mexico

This week the U.S. Department of State extended its travel alert for Mexico, adding two Mexican states to the areas it warns U.S. travelers to avoid. The updated alert includes Durango and Coahuila in northern Mexico.

The killing of four U.S. citizens in late 2009 and early 2010 in Gomez Palacio, Durango, contributed to the updated alert, the State Department said in a release. "The cities of Durango and Gomez Palacio in the state of Durango, and the area known as 'La Laguna' in the state of Coahuila, which includes the city of Torreon, experienced sharp increases in violence," the department said. Drug trafficking is the primary cause of the rise in violence, the release said.

The alert could be a further blow to Mexican tourism, which is recovering after reports of violence and H1N1 virus concerns significantly reduced the number of tourists in Mexico during 2009. The State Department continued to urge travelers to delay unnecessary travel to Michoacán in central Mexico and Chihuahua.

Brake override software-Toyota Canada to install on extended range of vehicles


TORONTO --Toyota Canada is offering to install new protection software on three more vehicles, on Tuesday adding the Tacoma, Venza and Sequoia to a list of cars and trucks eligible for a brake override system intended to protect against brake or accelerator pedal problems.

The move is part of an enduring attempt by Toyota to resolve its tattered public image, but analysts questioned whether the move could backfire.
"Toyota's got to be very careful," said Tony Faria, co-director of the automotive research centre at the University of Windsor.

"Almost anything they do is going to get media attention, and while they're going to try and organize what they're doing, the way the actions they take are interpreted are not necessarily always going to be the way Toyota is hoping those actions are going to be interpreted."

The Japanese automaker has recalled 8.5 million vehicles worldwide in recent months to deal with safety problems involving gas pedals, floor mats and brakes, some of which have been linked to fatal accidents. In Canada, a total of 270,000 vehicles have been recalled due to a problem involving sticky accelerator pedals.

Last rocket to be fired in Utah as final space shuttle launch nears


A remarkable era will come to an end later this week in Northern Utah. The people who've been building space shuttle rockets for more than a third of a century will perform the last test firing in Utah. The program is rapidly coming to an end, leaving many questions about the future of the space program and thousands of jobs in Northern Utah.

A train will soon take rockets to Florida for the last listed space shuttle launch. At ATK, formerly Thiokol, they've been making the massive rockets since the mid-70s. When there's a shuttle launch in Florida, Harry Reed, ATK Shuttle Program Manager, travels there every time.

Hacking Inquiry Puts China’s Elite in New Light




SHANGHAI — With its authentic reputation and its scientific bent, Shanghai Jiaotong University has the feel of an Ivy League institution.
The university has alliances with elite American ones like Duke and the University of Michigan. And it is so rich in science and engineering talent that Microsoft and Intel have moved into a research park directly nearby to the school.
But Jiaotong, whose sprawling campus here has more than 33,000 students, is facing an unlikable question  is it a base for sophisticated computer hackers?
Investigators looking into Web attacks on Google and dozens of other American companies last year have traced the intrusions to computers at Jiaotong as well as an unclear vocational school in eastern China, according to people briefed on the case.
Security experts concern that it is hard to trace online attacks and that the digital footprints may be a “false flag,” a kind of distraction intended to throw investigators off track.
But those with knowledge of the examination say there are consistent clues that suggest the highly complicated attacks may have originated at Jiaotong and the more obscure campus, Lanxiang Vocational School in Shandong Province, an institution with ties to the Chinese military.

American Evan Lysacek defends his victory over Russian Evgeni Plushenko


VANCOUVER, B.C. U.S. figure skater Evan Lysacek presently wanted to enjoy the Olympic gold medal he never expected but always wanted hours after his distress victory over Russian Evgeni Plushenko in the Olympic men's figure skating competition Thursday.
Instead, Lysacek spent Friday lasting attacks on the authority of his title from Russians and others disappoint both with his strategic approach and the judges verdict to give him a narrow victory over the 2006 gold medal winner.
Russian Prime Minister Vladimir Putin sent Plushenko, who claimed the silver medal, a telegram telling him his "silver was as good as gold" and he "performed the most proficient program on the Vancouver ice." Russian commentators decried the result, and two-time Olympic silver medal winner Elvis Stojko said in a column for Yahoo that Lysacek's skate wasn't "Olympic champion material" and "the judges made a mockery" of the event by rewarding Lysacek.

Technology, medical tests 'changing the face of health care'

A boom in medical technology over the past decade or two has led to a course in certain medical tests and increased prescription drug use, say authors of a report that provides a snapshot of Americans' health today.

Imaging, assisted reproductive technologies, direction drugs and knee replacements have all seen a dramatic rise since the early '90s, says Amy Bernstein, the report's lead author, a health scientist for the National Center for Health information. The center, part of the Centers for Disease Control and Prevention, released the 33rd annual Report on the Nation's Health Wednesday. It includes a special section on health technology.

"There are newer and better technologies all the time, and they're changing the face of health care and practice patterns," Bernstein says.

She points to report findings that show the use of stain drugs, which lower cholesterol, increased almost tenfold from 1994 to 2006 in adults over age 45.

"One of the reasons cholesterol is declining and people are living longer with heart disease is because we have improved drugs. Technologies can be very helpful," she says.

Smartphone:Microsoft unveils new smartphone software


After three years of evading questions over why it was so far behind Apple's iPhone, Microsoft is staging a comeback in the mobile business with a remarkably redesigned mobile operating system.

The company said Monday it will retire Windows Mobile 6.5 this year and has returned from the drawing board with Windows Phone 7 Series, a system that breaks free of the previous PC-centric design.
Chief Executive Steve Ballmer introduced the new system at the global Mobile World Congress in Barcelona, Spain.

For Microsoft, the progress could be a pick up again for a mobile business unit that some believe has been missing from action during a period of major innovation.

With the new software, Microsoft also showed a shine of the potential locked inside the company's apparently distinct businesses, integrating them into a single device that could be greater than the sum of its parts — video-gaming service Xbox Live, music and video player Zune HD, search engine Bing, Office productivity software and Outlook e-mail.

Samsung unveils new smart phone with own software




BARCELONA, Spain — Samsung Electronics Co. the prime maker of cell phones for the U.S. market, on Sunday revealed the first phone running Samsung's own "smart" software system, bada.
With bada, Korea-based Samsung is taking the TouchWiz system used on its touch-screen non-smart phones and making it the basis of a smart phone platform to take on Apple Inc.'s iPhone and Research In Motion Ltd.'s BlackBerry. Samsung also makes phones based on other competing smart phone systems Android, created by Google Inc., and Symbian, of which Nokia Corp. is a major backer.
J.K. Shin, the president of Samsung's phone division, said the goal of bada was to expand the market for smart phones, making them available to people across the world who have made with non-smart phones.
The new phone, dubbed the Wave, is a touch screen phone like the iPhone. It features a highly drenched, high-resolution screen using organic light emitting diodes, or OLEDs. Samsung said the phone will go on sale in April, but did not say if the U.S. would be one of the launch markets, nor did it say what the phone would cost.
To support the Wave and existing phones using TouchWiz, Samsung is launching online applications stores in 50 countries this year, including the U.S. Most major phone makers now operate application stores, or make phones that use stores administered by others, like Google.
Samsung revealed the phone in Barcelona a day ahead of the start of Mobile World Congress, the world's largest cell phone trade show.

4G technology-Trai starts process to give recommendations soon

Even as the government debates when the auction of spectrum for the third-generation telephony might take place, the Telecom Regulatory Authority of India (Trai) today started consultations for the next level of telecom services.

The fourth-generation, or 4G, technology, known as the ultra-broadband, offers download at faster speed and high definition video on demand, among other services.

“Yes. We are starting the process and would come out with a conference paper to look into diverse issues relating to 4G telecom services,” Trai Chairman J S Sarma said.

He, however, said firmly that this did not mean the 3G process be skipped, as the government had taken ultimate step and might auction the spectrum soon.

“(The auction of) 3G has been delayed badly I don’t want 4G or Long-Term Evolution (LTE) to convene the same fate. Other countries are catching up with 4G and that is why we are taking advance action,” he said.

The 4G services, or LTE, are a successor to 3G and 2G standards, with the intend to offer a wide range of data rates up to ultra-broadband (gigabit-speed) internet access to mobile, as well as stationary users.

Trai would look into the various aspects, including spectrum band to be allotted for 4G services and quantum and modes of allotment to operators.

SIM: Indian outsourcing companies get a new competitor

In 2004,the height of the American presidential campaign conquered among other things by offshoring and a jobless recovery, HCL's Vineet Nayar set off a firestorm with a statement that American graduates were not employable.

As trade unions seethed and politicians fumed, two men looked at the reaction the comments had caused and wondered if there was a business opportunity.

Since offshoring was considered purely Indian phenomenon and sensing a backlash to the process in the years ahead, Debashish Sinha and Neeraj Gupta two IT industry executives in the US began gently working on an alternative that would appeal to many companies and the political establishment.

It took them five years to come up with a real plan and get patron funding. System In Motion (SIM), a Michigan-based start up, launched few months ago plans to challenge the traditional offshore outsourcing market leaders by delivering low cost services from locations such as Ann Arbor.

With the Indian outsourcing industry still being viewed by some in the US as one of the reasons for the country’s 'jobless recovery', this start up is promising to create more than 1,100 jobs over next five years in Michigan, home to Ford, General Motors and Chrysler-the Detroit’s big three.

Transfer of sensitive tech to new firm under a cloud

A susceptible defense-related technology, developed by scientists at a research and development centre of the Union IT ministry, has been transferred to a company with links to a South Korean firm and controlled by a person facing trial for alleged software theft documents.

The transfer of technology (ToT) was made in August 2007 by the Society for Applied Microwave Electronics Engineering and Research. The end users of the product are the defense and electronics sectors. Whenever there is a necessity for mass production of its products being an R&D facility, goes in for a ToT agreement with an industry player having the required technical expertise, manufacturing experience and sound financial background.

However, the transfer of the integrated radio and line modem (IRLM), said to be an advanced missile controlling technology used by the defense forces, to a company called M/s Sam Shin Precision Pvt Ltd, which does not appear to have any prior manufacturing experience or expertise, has come under a cloud.

Sam Shin is controlled by P Rathinavel, who was arrested in September 2005 by the cyber wing of the Central Crime Branch on the charge of stealing software for manufacturing digital electrical meters from a company called Omni Agate, in which he was working as technical director.

Latest Annoyance :Toyota Prius Brake Problems

Toyota owners, and for that issue Lexus and Scion owners, should be outraged at the way that the Toyota Motor Corporation has responded in the rouse of known engineering and technology glitches which have caused numerous accidents that have injured or killed many. Evidence is emerging that Toyota knew about its gas pedal problems as far back as early 2007, but now a new problem is emerging: the latest generation hybrid Prius may have brake problems.


Slipping Brakes

The problem with the Toyota Prius surfaced when customers began to complain of brakes slipping under certain conditions. Beginning in late January, Toyota tweaked the software scheming the brakes of cars which had yet to be sold, but they still have not offered a secure for customers who already own the car. The third generation Prius has been available since early 2009.

Complaints from American drivers have been sent to the National Highway Safety Transportation Administration (NHTSA) who has been behind a pair of investigations related to the runaway Toyota issue. Japan’s Ministry of Transportation is also investigating Prius complaints logged by Japanese drivers.


ABS Braking

According to Automotive News, Toyota Managing Officer Hiroyuki Yokoyama said yesterday that the slipping feeling is caused by a lag time in the shift between the car’s regenerative braking system and the antilock braking system.
That situation has become most perceptible on slippery or bumpy roads particularly in December as icy road conditions resulted in more frequent use of ABS braking. Yokohama added, “When ABS comes into play, you may feel a little bit of slip, but if you continue to apply the brake it will work. It may cause customers a little unease."


Millions Recalled

Toyota’s problems continue to rise and have extended recalls to cover more cars than it sold last year. Thus far, at least eight million vehicles in North America, Europe, Japan, and elsewhere are subject to a recall, with fixes ranging from replacing the driver’s floor mat to swapping out the accelerator pedal.
Those repairs are expected to commence by early next week with all cars serviced within the next few months.

Meanwhile, not selling its eight affected models has hurt Toyota economically. According to the Detroit Free Press the automaker is losing $100 million daily with no date set when the company can fully recommence sales.

Symbian phone OS goes open source

The group behind the world's most trendy smartphone operating system - Symbian - is giving away "billions of dollars" worth of code for free.

The Symbian Foundation's decision to make its code open source means that any organization or individual can now use and modify it "for any purpose".

Symbian has shipped in more than 330m mobile phones, the foundation says.

It believes that the move will focus new developers to work on the system and help speed up the pace of improvements.

"This is the largest open source migration effort ever," Lee Williams of the Symbian Foundation told BBC News.



Evolutionary barrier

Finnish mobile phone giant Nokia bought the software in 2008 and helped establish the non-profit Symbian Foundation to manage its development.

The foundation includes Nokia, AT&T, LG, Motorola, NTT Docomo, Samsung, Sony Ericsson, STMicroelectronics, Texas Instruments and Vodafone.

The group has now released what it calls the Symbian platform as open source code. This platform unites different elements of the Symbian operating system as well as components - in particular, user interfaces - developed by individual members. It can be downloaded from the foundation's website.


Mind share

Symbian development is currently conquered by Nokia, but the foundation hoped to reduce the firm's input to "no more than 50%" by the middle of 2011, said Mr Williams.

"We will see a dramatic shift in terms of who is contributing to the platform."
However, said Mr Williams, the foundation would monitor phones using the platform to ensure that they met with minimum standards

Nokia N97 Mini - System Software Updated

Following the recent Nokia N97 update, an update for the very similar Nokia N97 Mini Symbian-based smartphone has also been released. This is actually quite related to the one that the original N97 received, despite the fact that it does throw in a few additional tweaks.

What's In This Update

This update brings the N97 Mini up to firmware v11.0.045, and it addresses a few items found since the last major update (v11).

Some of the enhancements include:
  • More free RAM after boot
  • Improved call reliability
  • Browser improvements
  • Music Player improvements
  • Image and Video Stability improvements and more
An Overview of the Nokia N97 Mini

Despite its name, the N97 Mini is only slightly smaller than its big brother. It does have a smaller touchscreen, but at the same resolution: 640 x 360 pixels.

It also features less internal memory (8 GB vs. 32 GB), but still includes a microSD memory card slot supporting up to 16 GB cards. And the camera uses the 5 megapixel, Carl Zeiss Tessar lens, auto-focus and flash also found in the N97.

Other features include Wi-Fi, Bluetooth, and a GPS receiver.

BIOS

In IBM PC Compatible computers, the Basic Input/Output System (BIOS) , also known as the System BIOS, is a de facto standard defining a firmware interface.

The BIOS is boot firmware, designed to be the first code run by a PC when powered on. The initial function of the BIOS is to identify, test, and initialize system devices such as the video display card, hard disk, and floppy disk and other hardware. This is to prepare the machine into a known state, so that software stored on compatible media can be loaded, executed, and given control of the PC. This process is known as booting, or booting up, which is short for bootstrapping.

BIOS programs are stored on a chip and are built to work with various devices that make up the complementary chipset of the system. They provide a small library of basic input/output functions that can be called to operate and control the peripherals such as the keyboard, text display functions and so forth. In the IBM PC and AT, certain peripheral cards such as hard-drive controllers and video display adapters carried their own BIOS extension ROM, which provided additional functionality. Operating systems and executive software, designed to supersede this basic firmware functionality, will provide replacement software interfaces to applications.

Transceivers Handle Signal and Power Over a Single Coax Cable

EqcoLogic’s EQCO800SC transceiver circuit enables full duplex communication together with power transmission over a single, low cost coaxial (COAX) cable, at speeds of up to 1.25 Gbit/second and with cable lengths up to 100 m. It supports a number of key protocols including IEEE 1394b (FireWire), Ethernet (Fast and Gigabit), and LVDS. The transceiver circuit is designed for automotive applications, where it enables high performance and low cost networking with COAX cables and connectors in entertainment, information and driver assist applications.

The EqcoLogic device is also suited for industrial and security cameras where FireWire cameras have established a strong position. With the EQCO800SC circuit, low-cost, long haul connections can be made using pre-existing COAX infrastructure. This allows the conversion of an existing analog camera system (using 75 ohm COAX cabling) to digital without the need to re-lay cable. Installations with COAX cables and connectors are intrinsically flexible and can include slip rings to allow rotation, for example, of a camera platform.

Electrical engineering


Electrical engineering, sometimes referred to as electrical and electronic engineering, is a field of engineering that deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical power supply. It now covers a range of subtopics including power, electronics, control systems, signal processing and telecommunications.

Electrical engineering may or may not include electronic engineering. Where a distinction is made, usually outside of the United States, electrical engineering is considered to deal with the problems associated with large-scale electrical systems such as power transmission and motor control, whereas electronic engineering deals with the study of small-scale electronic systems including computers and integrated circuits. Alternatively, electrical engineers are usually concerned with using electricity to transmit energy, while electronic engineers are concerned with using electricity to transmit information.

IEEE Edison Medal

The Edison Medal is presented by the Institute of Electrical and Electronics Engineers (IEEE) "for a career of meritorious achievement in electrical science, electrical engineering or the electrical arts." It is the oldest and most coveted medal in this field of engineering in the United States The award consists of a gold medal, bronze replica, small gold replica, certificate and honorarium. The Edison Medal may only be awarded to an individual.

The Edison Medal, named after the inventor and entrepreneur Thomas Edison, was created on 11 February 1904 by a group of Edison's friends and associates. Four years later the American Institute of Electrical Engineers (AIEE) entered into an agreement with the group to present the medal as its highest award. The first medal was presented in 1909 to Elihu Thomson. Other recipients of the Edison Medal include George Westinghouse, Alexander Graham Bell, Nikola Tesla, Michael I. Pupin, Robert A. Millikan (Nobel Prize 1923), and Vannevar Bush. A complete list can be found here.

After the merger of AIEE and the Institute of Radio Engineers (IRE), in 1963, to form the IEEE, it was decided that IRE's Medal of Honor would be presented as IEEE's highest award, while the Edison Medal would become IEEE's principal medal.

Intel Atom Processor


Intel Atom is the brand name for a line of x86 and x86-64 CPUs (or microprocessors) from Intel, previously code-named Silverthorne and Diamondville processors, designed for a 45 nm CMOS process and intended for use in MIDs, smart phones and ultra-mobile PCs meant for portable and low-power applications. Ultimately, it ended up being a preferred processor for netbooks.

Because they were targeted for low power consumption rather than performance the Intel Atoms benchmark significantly lower than processors designed for laptop and desktop use. The rough benchmark used by Intel is that the Atoms have about "half the performance" of (Dothan-512 core) Celeron 1.8 GHz processors.

OSI model



The Open Systems Interconnection Reference Model (OSI Reference Model or OSI Model) is an abstract description for layered communications and computer network protocol design. It was developed as part of the Open Systems Interconnection (OSI) initiative. In its most basic form, it divides network architecture into seven layers which, from top to bottom, are the Application, Presentation, Session, Transport, Network, Data-Link, and Physical Layers. It is therefore often referred to as the OSI Seven Layer Model.

A layer is a collection of conceptually similar functions that provide services to the layer above it and receives service from the layer below it. For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of the path.

Metropolitan area network

Metropolitan area networks, or MANs, are large computer networks usually spanning a city. They typically use wireless infrastructure or Optical fiber connections to link their sites.

A MAN is optimized for a larger geographical area than a LAN, ranging from several blocks of buildings to entire cities. MANs can also depend on communications channels of moderate-to-high data rates. A MAN might be owned and operated by a single organization, but it usually will be used by many individuals and organizations. MANs might also be owned and operated as public utilities. They will often provide means for internetworking of local networks. Metropolitan area networks can span up to 50km, devices used are modem and wire/cable

A Metropolitan Area Network (MAN) is a large computer network that spans a metropolitan area or campus. Its geographic scope falls between a WAN and LAN. MANs provide Internet connectivity for LANs in a metropolitan region, and connect them to wider area networks like the Internet.

Infrared (IR)

Abbreviated as IR, infrared is a wave of light that in the area beyond the visible part of the color spectrum. While it is invisible to human eye infrared is often used to enhance visibility when using night vision devices.

An invisible band of radiation at the lower end of the visible light spectrum. With wavelengths from 750 nm to 1 mm, infrared starts at the end of the microwave spectrum and ends at the beginning of visible light. Infrared transmission typically requires an unobstructed line of sight between transmitter and receiver.

Widely used in most audio and video remote controls, infrared transmission is also used for wireless connections between computer devices (see IrDA) and a variety of detectors (see IR detector). See IR remote control and IRED.

Frame check sequence

A frame check sequence (FCS) refers to the extra checksum characters added to a frame in a communication protocol for error detection and correction. Frames are used to send upper-layer data and ultimately the user application data from a source to a destination. The data package includes the message to be sent, or user application data. Extra bytes may be added so frames have a minimum length for timing purposes. LLC bytes are also included with the Data field in the IEEE standard frames. The LLC sublayer takes the network protocol data, which is an IP packet, and adds control information to help deliver the packet to the destination node. Layer 2 communicates with the upper layers through LLC.


All frames and the bits, bytes, and fields contained within them, are susceptible to errors from a variety of sources. The FCS field contains a number that is calculated by the source node based on the data in the frame. This number is added to the end of a frame that is sent. When the destination node receives the frame the FCS number is recalculated and compared with the FCS number included in the frame. If the two numbers are different, an error is assumed, the frame is discarded. The sending host computes a checksum on the entire frame and appends this as a trailer to the data. The receiving host computes the checksum on the frame using the same algorithm, and compares it to the received FCS. This way it can detect whether any data was lost or altered in transit. It may then discard the data, and request retransmission of the faulty frame.

Wide Area Network (WAN)

The term Wide Area Network (WAN) usually refers to a network which covers a large geographical area, and use communications circuits to connect the intermediate nodes. A major factor impacting WAN design and performance is a requirement that they lease communications circuits from telephone companies or other communications carriers. Transmission rates are typically 2 Mbps, 34 Mbps, 45 Mbps, 155 Mbps, 625 Mbps (or sometimes considerably more).

Numerous WANs have been constructed, including public packet networks, large corporate networks, military networks, banking networks, stock brokerage networks, and airline reservation networks. Some WANs are very extensive, spanning the globe, but most do not provide true global coverage. Organisations supporting WANs using the Internet Protocol are known as Network Service Providers (NSPs). These form the core of the Internet.

Electromagnetic radiation

Electromagnetic radiation (sometimes abbreviated EMR) takes the form of self-propagating waves in a vacuum or in matter. EM radiation has an electric and magnetic field component which oscillate in phase perpendicular to each other and to the direction of energy propagation. Electromagnetic radiation is classified into types according to the frequency of the wave; these types include (in order of increasing frequency): radio waves, microwaves, terahertz radiation, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. Of these, radio waves have the longest wavelengths and Gamma rays have the shortest. A small window of frequencies, called visible spectrum or light, is sensed by the eye of various organisms, with variations on the limits of this narrow spectrum.

Electromagnetic waves were first postulated by James Clerk Maxwell and subsequently confirmed by Heinrich Hertz. Maxwell derived a wave form of the electric and magnetic equations, revealing the wave-like nature of electric and magnetic fields, and their symmetry. Because the speed of EM waves predicted by the wave equation coincided with the measured speed of light, Maxwell concluded that light itself is an EM wave.

Impact factor

The impact factor, often abbreviated IF, is a measure of the citations to science and social science journals. It is frequently used as a proxy for the importance of a journal to its field. The Impact factor was devised by Eugene Garfield, the founder of the Institute for Scientific Information, now part of Thomson, a large worldwide US-based publisher. Impact factors are calculated each year by Thomson Scientific for those journals which it indexes, and the factors and indices are published in Journal Citation Reports. The publication of each year covered occurs in the summer of the following year. For example impact factors for 2008 will be published in the summer of 2009. Some related values, also calculated and published by the same organization, are:

* The immediacy index: the number of citations the articles in a journal receive in a given year divided by the number of articles published.
* The cited half-life: the median age of the articles that were cited in Journal Citation Reports each year. For example, if a journal's half-life in 2005 is 5, that means the citations from 2001-2005 are half of all the citations from that journal in 2005, and the other half of the citations precede 2001.
* The aggregate impact factor for a subject category: it is calculated taking into account the number of citations to all journals in the subject category and the number of articles from all the journals in the subject category.

Virtual LAN

A virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that communicate as if they were attached to the Broadcast domain, regardless of their physical location. A VLAN has the same attributes as a physical LAN, but it allows for end stations to be grouped together even if they are not located on the same network switch. Network reconfiguration can be done through software instead of physically relocating devices.

VLANs are created to provide the segmentation services traditionally provided by routers in LAN configurations. VLANs address issues such as scalability, security, and network management. Routers in VLAN topologies provide broadcast filtering, security, address summarization, and traffic flow management. By definition, switches may not bridge IP traffic between VLANs as it would violate the integrity of the VLAN broadcast domain.

Power factor

The power factor of an AC electric power system is defined as the ratio of the real power flowing to the load to the apparent power , and is a number between 0 and 1 (frequently expressed as a percentage, e.g. 0.5 pf = 50% pf). Real power is the capacity of the circuit for performing work in a particular time. Apparent power is the product of the current and voltage of the circuit. Due to energy stored in the load and returned to the source, or due to a non-linear load that distorts the wave shape of the current drawn from the source, the apparent power can be greater than the real power.

In an electric power system, a load with low power factor draws more current than a load with a high power factor for the same amount of useful power transferred. The higher currents increase the energy lost in the distribution system, and require larger wires and other equipment. Because of the costs of larger equipment and wasted energy, electrical utilities will usually charge a higher cost to industrial or commercial customers where there is a low power factor.

American Institute of Electrical Engineers

The American Institute of Electrical Engineers was a United States based organization of electrical engineers that existed between 1884 and 1963 (when it merged with the Institute of Radio Engineers (IRE)). The 1884 founders of the American Institute of Electrical Engineers (AIEE) included some of the most prominent inventors and innovators in the then new field of electrical engineering, among them Thomas Alva Edison, Elihu Thomson, Edwin J. Houston, and Edward Weston.

The purpose of the AIEE was stated "to promote the Arts and Sciences connected with the production and utilization of electricity and the welfare of those employed in these Industries: by means of social intercourse, the reading and discussion of professional papers and the circulation by means of publication among members and associates of information thus obtained." The first president of AIEE was Norvin Green, president of the Western Union Telegraph Company. Other notable AIEE presidents were Alexander Graham Bell (1891-1892), Charles Proteus Steinmetz (1901-1902), Schuyler S. Wheeler (1905-1906), Dugald C. Jackson (1910-1911), Michael I. Pupin (1925-1926), and Titus G. LeClair (1950-1951).

Phenethylamine

Phenethylamine, or β-phenyl ethylamine or 2-phenylethylamine, is an alkaloid and monoamine. Phenethylamine also has a constitutional isomer α-phenylethylamine (1-phenylethylamine), which has two stereoisomers: (R)-(+)-1-phenylethylamine and (S)-(-)-1-phenylethylamine. In the human brain, 2-phenethylamine is believed to function as a neuromodulator or neurotransmitter (trace amine). Phenethylamine is a natural compound biosynthesized from the amino acid phenylalanine by enzymatic decarboxylation. It is also found in many foods such as chocolate, especially after microbial fermentation. However trace amounts from food are quickly metabolized by the enzyme MAO-B, preventing significant concentrations from reaching the brain.
Phenylethylamine is a precursor to the neurotransmitter phenylethanolamine.

D-Phenylalanine increases the brain content of phenylethylamine .Phenylethylamine has been shown at least indirectly to satisfy the four main criteria required to demonstrate that a neuroamine sustains mood and that its deficit can be responsible for depression.Antidepressant drug therapy is an indirect (pharmacological) "replacement" of brain phenylethylamine .Substituted phenethylamines are a broad and diverse class of compounds that include stimulants, hallucinogens, entactogens, anorectics, bronchodilators, and antidepressants.

MRI Scans

Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord.

During the scan, you lie on a table that slides inside a tunnel-shaped machine. Doing the scan can take a long time, and you must stay still. The scan is painless. The MRI machine makes a lot of noise. The technician may offer you earplugs.

Before you get a scan, tell your doctor if you

* Are pregnant
* Have pieces of metal in your body. You might have metal in your body if you have a shrapnel or bullet injury or if you are a welder
* Have electronic devices in your body, such as a cardiac pacemaker

Transmission

In telecommunications, transmission is the process of sending, propagating and receiving an analogue or digital information signal over a physical point-to-point or point-to-multipoint transmission medium, either wired or wireless. Tranmission technologies and schemes typically refer to physical layer protocol duties such as modulation, demodulation, line coding, equalization, error control, bit synchronization and multiplexing, but the term may also involve higher-layer protocol duties, for example digitalization of an analog message signal, and source coding (compression).

Transmission of a digital message, or of a digitized analog signal, is known as data transmission or digital communication.

Electric vehicles in 1959

In 1959 the Henney Kilowatt was introduced and was the world's initial modern transistor-regulated electric car and the predecessor to the more recent battery electric vehicles such as General Motors EV1. Only 47 Henney Kilowatts were created, 24 being sold as 1959 models and 8 as 1960 models. It is not clear what happened to the other 15 built but it could be probable that they were sold as 1961 or 1962 models. None of the 8 1960 models were sold in the direction of the public because of the high manufacturing costs, but were sold to the electric cooperatives who funded the project.

It is estimated that there are connecting four and eight Henney Kilowatt battery electric vehicles still in existence with at least two of the survivors still driven at times.

Battery electric vehicles had issues with high battery costs, with restricted travel distances, with charging time and the lifespan of the battery, although advancements in battery technology has addressed a lot of those problems.
