Tech 2.0 for Thursday, March 27, 2014:

Visionary or looney? Zuckerberg on spending spree:

Facebook's two biggest acquisitions yet are raising some eyebrows. Longtime technology analyst Roger Kay wonders whether Mark Zuckerberg "is nuts" for agreeing to pay $2 billion for virtual reality company Oculus less than five weeks after inking a deal to buy WhatsApp for $19 billion. Other observers are calling the Facebook CEO visionary. The company's latest purchase doesn't have a consumer product on the market yet. Zuckerberg, though, sees long-term implications for Oculus' technology. He says the deal is "a long-term bet on the future of computing." Facebook's investors seemed to think Oculus' promise is too far off. The Menlo Park, Calif.-based social networking company's stock fell 7 percent on Wednesday to close at $60.38.

Security firms watch social media for feisty fans:

Watch what you tweet, sports fans. Security firms are turning to social media to figure out whether or not there's an increased risk of fans storming the court or becoming feisty during sports events. Officials say the practice of watching online chatter before a big game can help them tap into the mindset of a crowd, and helps them make decisions about how many guards to deploy at a venue. Firms won't say if they're watching fans' chatter during the NCAA basketball tournament. But Whelan Security, which helped secure the Metrodome in Minneapolis during the Vikings' final game there in December, says it checked online chatter to find out if fans were planning to storm the field and steal souvenirs.

The effectiveness of smartphone apps for alcoholics:

Trying to stay sober after recovering from alcoholism? There's an app for that. Actually, there is a series of smartphone apps to help people trying to keep from falling off the wagon. And a team of researchers that has looked at one of them say such apps can be a good way to help people avoid relapses into alcohol abuse. The study found that adults who were released from inpatient alcoholism treatment centers and got free sober smartphones reported fewer drinking days and more overall abstinence than those who got the usual follow-up support. One caveat to the report. The results of the study were based on patients self-reporting whether they resumed drinking. The study is published online in JAMA Psychiatry.
