[Q]: Kaitlyn Murphy   a 31-year-old resident was arrested earlier this week on felony defraud charges after she admitted to using glass to get out of paying for her food  a trick the woman claims to have learned from someone she knew in rehab.
 Murphy  confessed that she would carry glass in her purse when she went out to eat and would sprinkle it over her food. She even intentionally cut her mouth by chewing the glass to make her story more realistic.
The police reported that  Murphy  had visited eleven restaurants in Stuart  FL  from September 15 to September 26 â claiming to find glass in her food âafter eating most of her meals â Local 10 News reports.
After  Murphy  reported the hazard  the restaurants would either eat the cost of the meal  or offer gift cards and free food.
The police were eventually tipped off about  Murphy âs crime spree after restaurants started describing the same woman on social media  coming into their establishments and making the same claims.
The pressure of social media forced  Murphy  to turn herself in  where police found more glass shards in her purse.
In total  the police say  Murphy  cost restaurants hundreds of dollars in comped meals  gift cards  lost tips and lost food  as well as damaged the reputation of some servers and restaurants.
 Murphy  originally claimed that  she  did it because  she  couldnât afford the food  but later a manager said  Murphy  confessed  she  did it for the adrenaline rush â a high  she  was searching for after  she  had quit drugs and alcohol.
Just before  her  arrest   Murphy  was hired to work as a server in the area.

[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]: "We watched even this weekend  the Russians and their troll farms  and their internet folks  start hash-tagging out 'take a knee' and also hash-tagging out 'Boycott NFL '" said Lankford  whoâs a member of the Intelligence Committee. Theyâre trying âto raise the noise level in America to try to make a big issue  an even bigger issue as theyâre trying to just push divisiveness in the country. Weâve continued to be able to see that. Weâll see it again in our election time.â
FBI Director Christopher Wray  who testified about his agencyâs work  did not directly address  Lankfordâs  claim  but said the FBI is working to track Russian efforts to influence U.S. elections.
 Lankfordâs  spokesman said the senator has been receiving information about Russian trolls sowing discord in the U.S. for more than a year.
"Senator Lankford made an individual decision to start talking about this publicly  because he believes the American people should know '' said  the spokesman .
As an example   the spokesman  pointed to a Russian Twitter user called Boston Antifa but the geolocation of the account is in Vladivostok  Russia.
