Manage Red Hat Enterprise Linux like a Boss with Red Hat Ansible Content Collection for Red Hat Insights
Running IT environments means facing many challenges at the same time: security, performance, availability and stability are critical for the successful operation of today’s data centers.

Define your own Failure

Visual Studio Code for Windows
Every few years I find myself transitioning from one text editor to another. Starting with NotePad++ I moved to Sublime Text, then Atom, and more recently to Visual Studio Code. Just for clarification, I run a Mac but one reason I’ve liked VS Code so much is because of how it works across platforms, especially Windows.
