In the wake of the China attacks that resulted in Google’s public threat to leave China, the search giant is abandoning Windows due to concerns over security.

According to the Financial Times, the technology titan has been slowly phasing out the use of Windows internally since January, not long after it was assaulted by Chinese hackers. For example, new hires are no longer offered Windows PCs — the choices are now an Apple Mac computer or a PC loaded withLinux.

Google’s policies surrounding the internal use of Windows aren’t clear-cut, though. Some employees can still install Windows on their laptops, but not their desktop computers. However, Googlers need explicit permission from “quite senior levels” in order to keep using the Windows OS.

The move makes sense: Windows and Internet Explorer have been implicated as vectors in which hackers accessed personal accounts and confidential data from Google’s servers. And, of course, Microsoft is also one of Google’s primary competitors.

It’s important to note that later this year, Google is expected to release Chrome OS, the company’s web-centric operating system. However, the decision to leave Windows behind doesn’t seem to be motivated by the impending release of its experimental OS.

Windows/Linux: Open-source image editor MyPaint allows you to draw and edit images in fullscreen mode, on a limitless canvas that grows with your image and eliminates pesky scroll bars. It also works with pressure-sensitive tablets and touch screens for the creative set.

MyPaint includes a wide array of extensively customizable brushes. There’s also basic layer support, color history, and a color palette that includes complimentary colors. Unfortunately, copying and pasting your work directly into external image editing programs isn’t supported, but you can save your images in common formats like PNG to import them into other image editors.

It won’t replace Photoshop if you need a feature-rich program but, being essentially a simplified Corel Painter, it offers an intuitive painting space. MyPaint is open-source freeware for Windows and Linux systems only.
