Hi ulema,
I like to dev birdfeeders and hang them from trees in my backyard.
I also dev hypotheses for quantum gravity and do other things having to do with the very small.
And I do misc LINUX stuff, mostly to support my sysadmin tasks, mostly scripts in like BASH (Born Again Shell) and LINUX CLI (Command Line Interface) utilities; PHP (PHP Hypertext Preprocessor); Perl (I don't know what Perl stands for); JavaScript; and a bunch of really old stuff I never use anymore except for fun/reminiscence; and whatever is required for the embedded system I happen to be working on at the time (usually some kind of striped-down C variant).
I generally don't use script add-ons (what is Symfony?) unless the architecture was specifically designed to be built up that way from scratch, because I like my code to be efficient (a quirk I picked up from way back when that was actually necessary) and I like to understand what the code is doing; plus I can usually write what I need just as fast as I can learn the interface for the add-ons. And I only write for my own needs so I don't have to get involved with the other stuff.
