Enceladus:



The kernel does the Io action. When you run an Io code you have two choices. Wait for the kernel to execute the code or tell the kernel to inform you when it's done executing the code.

If you are waiting for the kernel, then you are blocking. If you told the kernel to inform you when it's done then you are non blocking and can do other things while the kernel is not done with executing the code.

Nice �. What about File and network system non-blocking. Well no need to stress on that. Same applies to process that access or poll resources from a central serving point.

An Engine is also a process.

If you said PHP is "very fast", then it's speed should be measured compared with other languages. And when you compare, you find out that PHP is actually slow.

in the real world PHP is slow. That's why Facebook built HHVM. That's why good developer/company would not build any performance critical web app in PHP.

It all depends. My suggestion would be to start with PHP (or Python) and MySQL for the backend, HTML, CSS and JS for the frontend. You can then venture into Python (or PHP), then Golang.

Whichever way, developers never stop learning. You can decide to start with Ruby and still get to the top.
