Sony stays in profit, revenue grows from strong smartphone sales

Sony reported a modest profit in its first fiscal quarter ended June 30, continuing a turnaround that started in the last fiscal year.

The company has also raised its revenue forecast for its current fiscal year on account of the depreciating Yen.

If the return to profitability in the last fiscal year mainly came from the sale of assets including its U.S. headquarters, a large Tokyo office complex and share holdings, the turnaround in the quarter came from improved sales of smartphones and the favorable impact of foreign exchange rates.

The company reported that its net profit was ¥3.5 billion (US$35 million) in the quarter, compared to losses of ¥24.6 billion in the same quarter last year. Revenue was up 13 percent to ¥1.7 trillion.

Samsung readies dual-mode 4G TDD/FDD LTE phones for China

Samsung Electronics is positioning itself to be one of the first handset vendors to tap into China’s upcoming market for 4G services by introducing new Galaxy S4 phones capable of operating on both FDD and TDD LTE networks. The South Korean company will bring FDD/TDD LTE dual-mode Galaxy S4 and Galaxy S4 mini phones to China once the country officially launches commercial 4G services, the company said on Thursday. Currently, most Western nations are deploying 4G networks using FDD LTE technology. But in China, the government has been heavily promoting the use of TDD LTE networks. The country’s largest carrier, China Mobile, with 740 million customers, has been building trial networks with the 4G standard.Local officials have said China will issue the 4G commercial licenses later this year. Research firm IDC expects that could be as soon as September. China is the world’s largest smartphone market, and Samsung reigns as the country’s top vendor with a 19 percent share, according to IDC. The research firm’s forecasts show that in 2014, a quarter of all smartphones shipped to China will be designed for 4G networks. By 2017, that figure will reach 50 percent Samsung’s dual mode phones will allow users to seamlessly roam over different LTE networks, the company said. The handset maker plans to launch other TDD-LTE devices in other markets in the third quarter.

Outside of China, TDD LTE networks are seeing growing adoption in certain nations in Europe, the Middle East, Asia and Oceania. 

In Australia, local carrier Optus will launch the FDD/TDD LTE dual-mode phones in a few weeks.

Researchers show ways to bypass home and office security systems

Many door and window sensors, motion detectors and keypads that are part of security systems used in millions of homes and businesses can be bypassed by using relatively simple techniques, according to researchers from security consultancy firm Bishop Fox.

The researchers presented some of the bypass methods they discovered in a talk at the Black Hat USA security conference in Las Vegas on Wednesday, but declined to name any vendors whose products are affected.

“We started looking at security sensors, going from the outside in, and we found a few implementation issues that we can take advantage of,” said Drew Porter, a senior security analyst at Bishop Fox.

For example, many door sensors rely on magnetic fields to work and if you hit them with a high enough magnetic field, they trip, Porter said. Window sensors are vulnerable to the same issue, he said.

The Regulatory State Is Strangling Startups, And Destroying Jobs

By John Chisholm, Contributor

In 1992, when I started my first company, you could freely hire a programmer or other contractor for as many hours or days per week as you could afford and as the individual was available.  As you grew, you could gradually increase the hours the contractor worked until you could afford to make him or her an employee.  It was a natural, frugal way to get a business off the ground. …read more

With the August recess just around the corner, Congressional Delegations (CODELS) are  gearing up for travels to various parts of the world. No matter where those delegations go, the press can be relied on to ridicule the travelers as itchy-footed wastrels, and their trips as junkets.  The public will mostly agree with the press’ point of view. …read more

Austerity In Europe: It Will Work If It's Ever Tried

By Jeffrey Dorfman, Contributor

The proponents of Keynesian-style deficit spending argue against austerity by claiming that it has failed in Europe. They point to the U.K., Italy, Greece, and onward, shouting that European government spending cuts have led to slow or negative growth and sky-high unemployment rates. The only problem with these arguments is that all the purported facts are misstated. …read more
