When I get into these things, it might take me a few months to maybe 
even years to learn something new fully. And some things only take a 
weekend. Depends on what skills one needs to get going with it. I have 
35+ years programming experience in many different languages, and 
tinkered in electronics even as young as age 7. But the thing is, while 
I learned the basics (and when Google came around, Googled for stuff I 
didn't know that I needed to apply to a project), and even took a couple 
online courses in programming, I find it's a matter of use it or lose 
it. If I don't use it regularly (like I do with PHP, HTML, CSS, Perl, 
and Python in my job), then I tend to forget almost all I learned and 
kinda end up Googling for help with everything or looking up my code 
snippets and notes.

But at the same time, I enjoy tinkering with stuff, even if I might 
forget a year or two later. For my own hobbies, I just get curious about 
some of the "new" (I know this stuff has been around awhile) technology 
out there and like to see how it all works.

I had done some C programming now and then (K & R C, ANSI C, Mix Power 
C, Borland C++, gcc, Visual C) and now anytime I do anything in C, I use 
gcc (and also valgrind, autotools, and I forgot what else I use but I 
use Kate for my editor for nearly everything and compile at command 
line). I still struggle with C because I don't use it much. However, I 
use a lot of stuff that has a similar structure to C such as perl and 
PHP. Funny thing is, I also learned Java but almost never use it!

Python is a scripting language so natively it doesn't get compiled, 
really. To compile Python code to binary .so for like Python libraries 
(which is NOT required but there are some uses for doing so), I use a 
program called 'cython' (in the debian repos) that converts Python code 
to C code, then uses gcc to compile the resulting C code. Does a decent 
job of it for what I was doing.

I actually haven't done much of that in *years* - since my OS9-Level II 
days. Got to brush up on that now.

Good to know. And thank you for all the really good information. I'm 
saving it for my "list to learn".
