The travel site Orbitz has partnered with Google to show a virtual walking tour of the neighborhood around a hotel. You and I know it as the Street View API, part of Google Maps (our Google Maps API profile).
This week Google announced support of three new APIs in it's upcoming beta release of Chrome 61. These APIs, integrated from existing W3C standards, include the Payment Request API for making payment checkouts easier, the Web Share API for implementing native sharing capabilities and the WebUSB API.
If you know how to develop mashups then you may be in line to win some very big prizes. To get a sense of just how much money and how many prizes, take a look at the ProgrammableWeb Contest Guide and you'll find that there have been more than 45 mashup contests thus far.
