Samsung keynotes CES with IoT message

Samsung Electronics CEO BK Yoon may not have dazzled the crowd at his opening keynote at CES, but he emphasized the central role that the Internet of Things will play in his company's future: "By 2017, 90 percent of all Samsung products will be IoT devices. Five years from now, every single piece of Samsung hardware will be an IoT device." At CES, Samsung also said it would use its Tizen OS in its smart TVs; it launched some low-key but practical home appliances, and it jumped into the market for external SSDs.

Sony chief speaks out on hacking, finally

Sony's CEO broke his silence on the hacking that disrupted Sony Pictures Entertainment last month, and said he's proud of its staff and partners for standing up to "extortionist efforts of criminals." Kazuo Hirai made the comments ahead of Sony's news conference at CES on Monday, and described the incident as "one of the most vicious and malicious cyberattacks that we've known."

Bad week for bitcoin

This comes just a day after a busy European bitcoin exchange halted trading on Monday after it detected problems with its "hot wallet," Coindesk reported. Bitstamp told users not to make deposits, but said it had ample offline reserves to cover deposits made prior to Monday morning. Coindesk says that Bitstamp took over much of the U.S. dollar bitcoin exchange business when Japan-based Mt. Gox failed in February last year. Meanwhile, IDG News Service reported earlier that police in Tokyo now suspect that most of the roughly US$370 million in bitcoin that disappeared in the Mt. Gox collapse probably vanished due to fraudulent transactions. Mt. Gox blamed a bug, exploited by hackers, but Tokyo police apparently think those losses amounted to just 1 percent of the total.

No-waste space exploration

Entrepreneur Elon Musk already has plenty of environmentalist cred as the chief of electric-car company Tesla. On Tuesday his less earthbound SpaceX venture was planning to take recycling to the next level, by launching a rocket and then landing its first stage on a barge, the New York Times reported. Unfortunately, the launch was scrubbed about 90 seconds before liftoff due to technical problems, but the company will try again at 5:09 a.m. Friday, said NBC News. If SpaceX can succeed in saving, and reusing, that 14-story-tall component, it does more than keeps the oceans clean of trash: it changes the economics of rocket launches.
