Google wants to show developers what Project Magenta can do with its new interactive experiment A.I. Duet. The company launched Magenta into the open-source community last year as a way for developers to explore music with neural nets.

A.I. Duet is designed to let users play a duet with their computers.

“Just play some notes, and the computer will respond to your melody,” wrote Alexander Chen, coder and musician for Google’s Creative Lab, in a blog post. “You don’t even have to know how to play piano—it’s fun to just press some keys and listen to what comes back. We hope it inspires you—whether you’re a developer or musician, or just curious—to imagine how technology can help creative ideas come to life.”

ReactOS 0.4.4 released with new improvements
ReactOS 0.4.4 was released this week, and a notable addition includes the incorporation of basic printing support. Right now, ReactOS is able to send print commands to a parallel port printer, but the ReactOS team wrote that “this is the first step toward universal support.”

ReactOS’ move toward universal support can be attributed to Colin Finck, a ReactOS engineer. Other improvements were made to the rendering of applications, where in the past the toolbars and buttons looked “visibly ajar or improperly aligned, [and] here the menus and icons look much, much more correct,” wrote the team.
