IT’S OFFICIAL: Jack Dorsey is Twitter’s permanent CEO, and he’ll also keep the reins at mobile payments company Square. “Twitter had previously said the CEO job would be a full-time position, which seemed to exclude Dorsey if he continued to run Square,” Reuters reports. “The move comes at a time when Twitter is working to rekindle user growth. Twitter’s second-quarter monthly average users grew at the slowest pace since the company went public in 2013. Dorsey has served as interim CEO of the microblogging service since former CEO Dick Costolo stepped down on July 1.”

YET ANOTHER BREACH: Discount brokerage firm Scottrade experienced a data breach around late 2013 or early 2014 and will offer identity protection services to about 4.6 million affected clients. “The affected database contains Social Security numbers and email addresses of clients, but hackers appeared to target names and addresses,” CNBC reports. “In a notice on its website, Scottrade stressed it had ‘no reason to believe’ that its trading platforms or client funds were affected. The company said it has taken ‘appropriate steps’ to boost its network security after the incident.”

TIME FOR A VACATION: Tesla and SpaceX CEO Elon Musk grew misty-eyed during a recent interview with a Danish television station while talking about his workload. “Creating a company is almost like having a child,” Musk said. “It’s almost like, how do you say your child should not have food?” “So once you have the company you have to feed it and nurse it and take care of it even if it ruins you?” asked his interviewer. “Yeah,” said Musk. As The Post reports, “After a long pause, Musk was asked how he got through the 2008 financial crisis. ‘Yeah,’ said Musk with a shake of his head. ‘Can we just break for a second?'”
