Linux container for ChromeOS

Recently, ChromeOS started to support Linux applications on ChomeOS. Google hasn't allowed ChromeOS to run native applications due to security reason. Finally, they found a way to support Linux application through the container technology.

It is worth to read a discussion on CrOSVM on Hacker News because the original author joined the discussion. Here is the article about ChromeOS Linux container.

There is a Youtube video:

Here is the readme about CrOSVM.

The interesting thing is that it is implemented with Rust. Google now seriously uses Rust of their product, which is a good news for the Rust community.

Rust & DRM

I was surprised that there are many low-level graphics projects written in Rust and I started looking into one of them: drm-rs. Then, I added an example for handling page-flip event.

drm-rs is a subproject of Smithay that is a wayland compositor written in Rust. It allows Rust applications to access the Direct Rendering Manger(DRM), a subsystem of the Linux Kernel. So, we could directly paint something into a frame buffer and render it on the display using DRM APIs.
