Facebook will start testing on its new cryptocurrency 'GlobalCoin' by the end of this year. It plans to fully roll out the stablecoin by the first quarter of 2020. Facebook plans to partner with banks and brokers in order to create places where people can exchange their currency into GlobalCoin. A number of online merchants are in talks with Facebook to accept the currency as payment. In order to combat fluctuations in the price of the currency, Facebook will peg the value of the currency to several existing currencies, including the US dollar, euro, and Japanese yen.

WhatsApp will start displaying in-app ads within the 'Stories' section of the app. This brings features that have been effective on Facebook and Instagram to WhatsApp's advertising.

A new maglev train that can reach speeds of up to 600 km per hour is currently being tested in China and is expected to reach production stage in 2021. The train will be able to transport people from Beijing to Shanghai in just three and a half hours, compared to the current four and a half hour flight. Maglev trains move on a magnetically powered cushion of air, rather than using wheels that are in contact with a track. China and Japan currently have operational maglev trains, some of which can travel faster than the new design.

SpaceX has launched 60 of its Starlink broadband satellites into the sky, creating a chain of satellites that could be observed by enthusiasts in a number of locations around the world. Some astronomers have expressed concern that the brightness from the satellites will interfere with observations of the night sky, especially when all 11,000 satellites are deployed. Elon Musk has confirmed that the satellites will be dark when the stars are visible.

School-age children now have the opportunity to go to YouTube summer camps. The camps, which can cost up to $1,000 a week, teach children how to draft storyboard ideas, interview people, and edit audio and video. While YouTube’s minimum age is 13, children can still run channels under the supervision of their parents. These channels will automatically be put on private and have comments disabled. Many parents interviewed did not see being a YouTube star as a viable career. However, the platform is now the most preferred source of entertainment for kids, and many children are aiming for careers on YouTube.

Baltimore has been struggling with a cyber attack that has crippled its systems and disrupted real estate sales, water bills, health alerts, and many other services within the city. The tool used to hack the city was developed by the National Security Agency, who lost control of the software when it was leaked in 2017. Since then, EternalBlue has caused massive damage around the world. The exploit, which targets Windows, was so successful that the NSA neglected to inform Microsoft of the vulnerability for more than five years until the exploit was released.
