Apple's W.W.D.C., and Energy Ministers Meeting: The Week Ahead

On Monday, Apple will show off its latest software and hardware, including Macs and iPads, at its annual conference for developers. The most anticipated item is a new voice-controlled speaker that would compete with the Amazon Echo and Google Home devices. Fans of Warren E. Buffett -- at least those with deep pockets -- have another chance to buy the billionaire lunch. An auction for a meal with Mr. Buffett, the chief executive of Berkshire Hathaway, at Smith & Wollensky in New York City began Sunday evening and runs through Friday, with bids starting at $25,000. The entire bid will support Glide, a nonprofit group that runs antipoverty programs in San Francisco.
