Johann Sebastian Bach is widely considered one of the great composers of baroque music. Bach lived and worked in Germany during the 18th century and is revered for the beauty of his compositions and his technical mastery of harmony and counterpoint. One form of music that Bach excelled in was a type of polyphonic hymn known as a chorale cantata. These are based on Lutheran texts and sung by four voices. The composer starts with a well-known tune which is sung by the soprano and then composes three harmonies sung by the alto, tenor, and bass voices.

Amazon has completed its first customer delivery by drone. The company made the used its Prime Air service for the first time to deliver goods to a customer in Cambridgeshire on December 7. Amazon founder and chief executive Jeff Bezos confirmed the delivery in a tweet. First-ever #AmazonPrimeAir customer delivery is in the books. Check out the video: https://t.co/Xl8HiQMA1S Amazon said a new private trial – also in the UK – will now deliver packages up to 2.3 kg in weight in 30 minutes or less using the drones, which it began testing earlier this year.

Amazon will now fly things to people's houses to deliver them. The company has completed the first ever Prime Air delivery, dropping an order off at someone's house just 13 minutes after they'd ordered it. For now, the drone deliveries are in a private – and largely mysterious – testing process. It is trying a range of different drones, it has said, flying them around different environments in the UK as part of its secretive tests. But eventually the company intends to roll out drone deliveries to everyone across the world.

Amazon.com has long talked about its ambitions for using drones to deliver small parcels to its legions of customers. Now, it appears the e-commerce giant is one step closer to that goal. On Wednesday, the company said that it has made its first autonomous drone delivery -- an order for an Amazon Fire TV streaming device and a bag of popcorn -- to a shopper in the United Kingdom. Jeffrey P. Bezos, the chief executive of Amazon and owner of The Washington Post, tweeted Wednesday morning that the box was at the customer's home 13 minutes after the order was placed.

At places like schools, hotels and tourist attractions, Microsoft Translator can help up to 100 people hold a live conversation in nine different languages. Imagine you're on a guided tour in Chartres cathedral in France along with tourists from Brazil, China, Russia and Germany -- but none of you speaks French. For the last few decades, you'd each need your own tour guide. A new app from Microsoft aims to flatten this multilanguage barrier, though. The Microsoft Translator app, running on your phone but relying on a network to Microsoft's servers, can translate your tour guide's words into eight other languages.

Are algorithms controlling humans? The Wednesday launch in Uber's hometown expands a public pilot program the company started in Pittsburgh in September.

Doug Hines, owner and designer for TrueCompanion, unveils Roxxxy, an artificially intelligent sex robot prototype, at the 2010 AVN Adult Entertainment Expo on January 9, 2010 in Las Vegas, Nevada (Photo by Ethan Miller/Getty Images). An oral sex enthusiast's plan to open a robot blowjob cafe in London is not the plot of some Westworld or Black Mirror episode or another Stepford Wives remake, it seems, but rather part of reality. Inverse reported last month that sextrepreneur Bradley Charvet will be bringing his vision for futuristic fellatio to Old London Town. According to the site, the cafe's robotic staff will provide customers with coffee, pastries, and oral sex between 6 a.m. and 11 p.m. daily, and may themselves represent a (potentially rented) selection of MySiliconeLoveDoll's finest gynoids. Charvet believes Londoners are ready for the service, or at least "willing to engage with the idea" of robotic workers entering their coffee and sex industries.

Amazon says it has successfully trialled its Prime Air drone delivery service in Cambridge, UK, by delivering a TV streaming stick and bag of popcorn directly to the garden of a nearby customer. The breakthrough suggests that autonomous aerial delivery could become a viable business sooner than thought, albeit only for customers with huge gardens, who live close to the delivery depot, and want items weighing less than 2.6kg. Additionally, while deliveries will be available seven days a week, the drones can only fly in daylight hours and clement weather. Currently, the trial is only open to two customers, but Amazon says it hopes to expand that to dozens in the coming months. For those customers, Prime Air is available for no extra cost.
