Avatao is a vast library of content that ranges from the security properties of various programming languages (Python, Java, C# or even C/C++) including stuff like how to set up AWS properly/securely, cryptography, web security etc. To add on top, this content is not merely a pre-recorded video or a static slidedeck, rather it is the actual thing running on a virtual machine and giving me access to tinker with it, along with helpful tips on how to progress in the tutorial. This way I can play with the tools just like I would in real-life. In programming languages, you get a simple IDE and can run right there on the spot. You really have everything set up, you don't need to install anything on your computer and spend hours just to try out a new language/technology. Instructions come via "avataobot", giving you one simple task at a time and the system validates that I did what I needed to do.
