If you’re like many Tableau customers, you have large buckets of data stored in Amazon S3. You might need to access this data frequently and store it in a consistent, highly structured format. If so, you can provision it to a data warehouse like Amazon Redshift. You might also want to explore this S3 data on an ad hoc basis. For example, you might want to determine whether or not to provision the data, and where—options might be Hadoop, Impala, Amazon EMR, or Amazon Redshift. To do so, you can use Amazon Athena, a serverless interactive query service from AWS that requires no infrastructure setup and management.
Economists have been puzzled in recent years by the so-called “productivity paradox,” the fact that the digital revolution of the past four decades hasn’t resulted in big gains in output per worker as happened with earlier technological upheaval. Many developed economies have actually seen productivity stagnate or decline.
Kate Chan, a 30-year-old digital marketer in Silicon Valley, first approached dating apps with a blend of curiosity and hope that they’d help her find a great guy. But after six months of dead-end mismatches with guys she thought were boring or work-obsessed, she has gone back to what she called “meeting the old-fashioned way”: without a screen. She now meets guys at do-it-yourself crafting meetups and her rock-climbing gym. “I didn’t want to rely on the algorithms anymore,” she said. “When it comes down to it, I really have to see that person face to face, to get that intuition, that you don’t get in a digital way.”
As companies rely more on machine learning and artificial intelligence (AI) to find the right job candidates, is recruitment in danger of losing that personal touch? Peter Lane, a 21-year-old who graduated last summer from Cardiff University with a degree in History, is hoping to get into business consulting. He’s applied for 55 jobs and secured around 15 interviews, but believes technology has hindered rather than helped his search. The interviews weren’t what he was expecting.
Two Venezuelan men went on a crime spree through Colorado, Idaho and Utah, cracking into seven ATMs and using software to trick the machines into spitting out as much as $98,000 at a time. The alleged crooks used a technique common in Latin America and Europe but very new in the U.S. called “jackpotting.” Thieves use a key or violently crack open the exterior of an ATM and then insert software into the machine’s computer hard drive instructing it to purge all of its cash.
Bitcoin and other “cryptocurrencies” have been much in the news lately, in part because of their wild gyrations in value. Michael Lee and Antoine Martin, economists in the New York Fed’s Money and Payment Studies function, have been following cryptocurrencies and agreed to answer some questions about digital money.
1) “With bitcoin there isn’t one designated validator. Instead, everybody in the bitcoin network could be picked, essentially at random, to validate recent transactions.” Validation is indeed the key and something not focused on at all by most people. What is validation?
2) Will bitcoin exchanges that are run from places like China survive in the global economy?
The Amazon-fueled grocery price war may have finally arrived. News that Amazon.com will start offering two-hour delivery from Whole Foods stores in four U.S. cities has the food world buzzing that competition is about to heat up in an industry that survives on razor-thin margins. In the six months since Amazon acquired the organic grocer, the e-commerce giant has been mum about its plans for its ballyhooed push into brick-and-mortar food retail.
