Air France crash: Black box signals located


French naval vessels detected a weak signal from the flight data recorders, according to French newspaper Le Monde. They said that a mini submarine has been dispatched on Monday to try and find the black boxes on the bottom of the ocean floor.

The “black boxes” may contain vital information that could help explain what happened when the Airbus A330 aircraft crashed into the sea en route from Rio de Janeiro to Paris on June 1.

Locator beacons, known as “pingers”, on the flight recorders send an electronic impulse every second for at least 30 days. The signal can be heard up to 2 km (1.2 miles) away.
French vessels involved in the search operation include a nuclear submarine with advanced sonar equipment and a research ship equipped with mini submarines.
The remote location in the Atlanticas well as the depth and surface of the ocean floor have made the search especially difficult and the wreckage could lie anywhere between a depth of 1 km (0.6 miles) and 4 km (2.5 miles).

An Air France spokeswoman said she could not confirm the report. The Transport Ministry and the air accident investigation office could not be reached immediately for comment.

Without the black boxes to help explain what went wrong, the investigation has focused on a flurry of automated messages sent by the plane minutes before it lost contact. One of the messages suggests external speed sensors had iced over, destabilising the plane’s control systems.

On Monday, 10 of the 50 bodies recovered from the flight were identified as Brazilian nationals.

Dental records, fingerprints and DNA samples were used to identify the bodies but investigators were also reviewing all remains, debris and baggage at a base set up in the town of Recife, the capital of Pernambuco. – (The Telegraph)

In abrupt turnaround, Olympus admits it hid losses

Japan's Olympus admitted on Tuesday it hid losses on securities investments dating back two decades, bowing to weeks of pressure to explain a series of baffling transactions that have put the future of the firm in doubt. The revelations by the 92-year-old company appear to vindicate ex-CEO Michael Woodford, who has staged a campaign since being sacked on October 14 to force the firm to come clean on nearly $1.5 billion in questionable payments. Olympus President Shuichi Takayama blamed Tsuyoshi Kikukawa, who quit as president and chairman on October 26, Vice-President Hisashi Mori and internal auditor Hideo Yamada for the cover-up, saying he would consider criminal complaints against them. The admission after weeks of denials shocked investors, sending shares in the endoscope and camera maker skidding almost 30 percent and prompting the biggest non-Japanese shareholder to demand the replacement of the entire board. "Ignorance is no defense," said Jo...

Last year's iPhones are destroying Samsung's new Galaxy S9 flagship smartphone - Bench Mark Results

Samsung announced the Galaxy S9 and Galaxy S9+, the latest entries in its flagship line of smartphones, at Barcelona's Mobile World Congress — but benchmark results are awkwardly showing the devices scoring significantly lower than many of their competitors. Benchmarks are synthetic tests that give numeric, quantifiable results. They are generally applications programmed to make the devices' systems-on-a-chip (SoC) run a series of tasks and determine how long it takes them to complete. AnandTech is a site that specialises in running rigorous tests like these, and its early findings on Samsung's latest devices are curious to say the least— particularly compared to the latest iPhones, Qualcomm's Snapdragon 845 — which will power most of the Android flagships this year — and even Samsung's own Galaxy S8 from last year. In a number of tests — such as web browsing, writing, data manipulation, and photo editing — the Galaxy S9's Exynos 9810 consistently deliv...

Microsoft nears $8.5 billion Skype buy in web shift

Microsoft is close to buying internet telephony network Skype in an $8.5 billion deal, a source familiar with the situation said, as it seeks to regain ground on growing rivals such as Google. Buying the loss-making but popular Skype would underline Microsoft's need to gain new customers and platforms for its software as smartphones and tablets explode in popularity. Skype, which allows people to make calls at no charge, would also give Microsoft a foothold in potentially the lucrative video-conferencing market as global businesses seeking to reduce expenditure shift to lower-cost ways of communicating. Microsoft has already put more energy and resources into mobile and internet technologies as the use of PCs, which underpin its Windows and Office franchise, is under threat. This change was starkly illustrated last year when Apple's portfolio of coveted consumer goods propelled it past Microsoft to become the world's most valuable technology company. The maker of iPhones an...
