Knowing Linux as a developer: followup

[techlists at phpcoderusa.com]

Hi,

This has been an interesting journey. AZPHP and a friend who owns a data 
center confirmed that most developers do not have any familiarity with 
Linux.  All these years I thought otherwise.

I still think there is value in knowing Linux as an opensource 
developer.  In my case I am a PHP developer.

Maybe being involved in Linux distracted me from becoming a better 
developer or maybe the opposite is true that my Linux involvement has 
made me a better developer.

In my mind I am exploring or assessing what I might have changed now 
that I am at this point in my life and having had the experience I have 
had with PHP since 2006.

In a recent post I asked about changing from dominate PHP being 
supported by Linux to Linux being dominate and supported by PHP or 
another language and DevOps came up.

Sorry I am thinking out loud and am hoping for your feedback.

I wonder if PHP has run it's course.  Maybe it is time to change course. 
  I need to do more research and give it more thought.

I like opensource Linux hosting.  I recently configured Ubuntu LAMP + 
BIND + Let's Encrypt + Postfix + Dovecot.  Doing so showed me how much a 
really do not know.

Any feedback is much appreciated.
