Windows 10 on Linux KVM with Intel GVT-g | FreeBSD Days
1. Introduction 1.1. Motivation Linux users are often required to switch to a Windows environment for using OS-restricted software such as Microsoft Office and VPN software.

However, it is required to reboot the

Linux Performance Analysis in 60,000 Milliseconds
You log in to a Linux server with a performance issue: what do you check in the first minute? At Netflix we have a massive EC2 Linux cloud, and numerous performance analysis tools to monitor and investigate its performance. These include Atlas for cloud-wide monitoring, and Vector for on-demand instance analysis. While those tools help us solve most issues, we sometimes need to login to an instanc

However, traditional text-based browsers lack JS and all other modern HTML5 support. Browsh is diff
