First Twitter, now LinkedIn. The career networking site narrowly beat Q1 expectations but reduced its forecast for the current quarter and the rest of the year. That revelation didn’t sit well with Wall Street: shares tumbled 25%. Twitter’s stock suffered a similar decline this week, after it likewise disappointed investors.

The gloves will come off in June. A “standstill” agreement that prevents Intel from launching a hostile takeover of Altera expires one month from today, sources tell Reuters. Apparently, the maker of chips for mobile and industrial Internet applications rebuffed a $54 per share offer from the chip giant in April.

Oracle co-CEO Safra Catz is intrigued by the idea of somebody else buying Salesforce. Her view, shared during the company’s first media day: “Helpful to us in the short- and medium-term.” Her peer, Mark Hurd, spent his time talking up Oracle’s cloud revenue, now “well over” $2 billion annually.

The biggest cloud of all? How the scrappy OpenStack federation—representing more than 100 companies—thinks it can offer scale that rivals the big-three public cloud service providers: Amazon, Google, and Microsoft.

Elon Musk’s latest grand plan, Tesla Energy. He wants consumers and small businesses to use the battery technology from electric vehicles to power homes and offices. The idea isn’t to replace the electric grid but to supplement it during periods of peak power demand.

Facebook is doing pretty darn well with small businesses. There are now more than 40 million “active” pages on the social network—it added more than 10 million in the last 12 months alone.

Now showing: Nielsen will track ad stats for Roku. Viewership metrics for video streaming services like Amazon and Netflix are notoriously elusive. The new deal will provide unprecedented visibility across more than 10 million devices.

Plus, teenagers certainly love Google's YouTube video network. Advertisers will be tougher to convince.

Apple and IBM want to address the world’s aging population. First stop? Japan

The next big focus for the companies’ expansive mobile partnership: serving the elderly. Fortune senior editor Andrew Nusca reports.

It's hard to believe that a sign with "Apple + IBM" on it once verged on sacrilegious, but it's becoming an increasingly common sight as two technology titans realize it's better to be friends than enemies.

IBM CEO Ginni Rometty and Apple CEO Tim Cook stood on stage together Thursday morning at IBM's Watson headquarters in New York City to announce a new partnership with Japan Post Group that aims to, ultimately, address the enormous accessibility challenges facing the world's growing population over age 65.

Rometty and Cook silently flanked Japan Post Group president and CEO Taizo Nishimuro, himself nearly 80 years old, as he spoke for more than 20 uninterrupted minutes about Japan's rapidly aging population and how IBM's apps and services, and Apple's iPads and iPhones, would help better connect the country's senior citizens to society.

“Japan is home to the fastest-aging society in the world,” Nishimuro said, gingerly and in halting English. Thirty-three million people—about 25% of Japan's total population—are age 65 or older, he said. That's going to increase to 40% in coming years.

Meanwhile, Japan Post Group—a postal service, a bank, a life-insurance provider—is moving toward what some believe will be the world's largest IPO, larger than Chinese e-commerce darling Alibaba. It's all a part of prime minister Shinzō Abe's economic plan, known as Abenomics, Nishimuro said.

“I gave myself a mission," he said. "Transform Japan Post Group into an integrated lifestyle support company."

As Nishimuro spoke, Cook, to his right, looked on with a twinkle in his eye and an admiring smile that blossomed into a full grin when Nishimuro mentioned the words "iPhone" and "iPad." Rometty, to his left, nodded and smiled every few lines.

The initiative breaks down into several parts. Apple will supply its iPad, whose operating system, iOS, already has a wealth of built-in accessibility features including settings for people with impaired vision or hearing, such as large type or dictation. IBM will custom-build applications through its Global Business Services group—its leader, Bridget van Kralingen, introduced the trio—that will include reminders or alerts about medications, exercise, and diet; as well as services for grocery shopping and job matching. All of them will run on IBM's MobileFirst for iOS cloud computing service, and Big Blue will layer in its own analytics, accessibility, and natural language technologies. Finally, IBM will train Japan Post employees to help them help the elderly.
