Q: Mariah Carey  undeterred by last yearâs performance  will take to the stage once again in Times Square to ring in the new year on live TV.
The star  along with Dick Clark Productions  issued a joint statement on Friday announcing  Carey  as the headliner for âDick Clarkâs New Yearâs Rockinâ Eve with Ryan Seacrestâ broadcast.
Careyâs manager blamed the production and technical difficulties that producers knowingly failed to fix. Dick Clark Productions called the accusations âoutrageous and frankly absurd.â  Carey  eventually broke her silence on the troubled performance  saying she was âmortifiedâ and that she intended to take a break from social media.
Now it seems as though everyone is ready to put the messy past behind them.  Carey  will join the likes of Britney Spears  Nick Jonas  Kelly Clarkson and Shawn Mendes as the world rings in 2018.
 Careyâs  forthcoming New Yearâs Eve performance will top an already merry holiday season for the star. In addition to performing her annual Christmas tour   Careyâs  famous single âAll I Want For Christmas Is Youâ has been played more than 100 million times this month alone  according to Forbes.

Q: “Initially there is a high number of players and then over time consolidation happens ”  Klaus Helmrich  said on Wednesday at the launch of a global user organization for Siemens’ MindSphere platform  which competes with General Electric’s Predix and others to help customers gather data from machines.
“I don’t think we will end up with one platform worldwide. There will be a handful or two handfuls in the mid to more distant future ”  Helmrich  said  comparing the proliferation of industrial software platforms with the smartphone industry  which has ended up being dominated by Apple and Samsung.
Siemens already has more than 800 000 intelligent sensors in buildings and machines  including trains and healthcare equipment  putting it in a strong position   Helmrich  said.
“It is a solid basis for the start of the business and makes us optimistic about scale effects ”  he  said  adding that being first to gather a critical mass of software developers and users is crucial to winning customers  much as Apple’s large developer community made its app store the most attractive.

Q: WASHINGTON â President Donald Trumpâs Russia probe lawyer  Ty Cobb  previously represented  billionaire Saudi Prince Alwaleed bin Talal   according to previously overlooked media reports and emails shared with HuffPost. The kingdom unexpectedly arrested  the prince  along with more than a dozen other prominent Saudis over the weekend in a move observers interpreted as a power play by Saudi Crown Prince Mohammed bin Salman.
Trump has close ties to Saudi Arabia and Prince Mohammed   the Saudi crown prince  said to be behind the arrests  including Alwaleedâs. Several weeks ago  White House adviser and Trump son-in-law Jared Kushner paid a secret visit to the kingdom and spent significant time with  Prince Mohammed   according to Politico and the Washington Post.
 The president  pushed the kingdom to use the New York Stock Exchange for the upcoming IPO of a portion of its national oil company  Aramco  in a tweet Saturday just hours before the crackdown.  He  also praised the kingdomâs policies in a call with Saudi King Salman  the crown princeâs father  the same day.
 Cobb  spent more than three decades working on white-collar cases before joining Trumpâs team.  He  resigned from  his  longtime firm  Hogan Lovells  in July. At the time  business news service ALM Media reported that  Cobb  had previously worked for members of the Saudi royal family  citing a Hogan Lovells page that now appears to have been taken down.
A 2012 Business Insider story by reporter Nicholas Carlson was more specific. The story said that  Cobb  had threatened to sue an American who had attempted a lawsuit against Alwaleed for allegedly threatening him with beheading and having him detained at gunpoint while he worked for the princeâs son.
Emails from Mark Mazo  another partner at Hogan Lovells  to Toronto-based businessman Alan Bender  who was representing a woman who claimed she had a secret marriage with Alwaleed  provide further evidence of  Cobb âs connection to the prince.
