No sweat, it wasn't condescending. I think for me, the problem is that my background is not in comp sci or software engineering. I am an aerospace engineer and am mostly self-taught save for what I retained from my first year C++ course back in the early aughts or gleaned from my sibling who is an ex Googler. So I end up not grokking a lot of tutorials targeted at professional programmers, maybe? I've written C, C++, C#, PHP, Python, lisp, Tcl, and Fortran and it was Fortran that presented the biggest hurdle in terms of finding quality info. I sometimes wonder why nobody wrote a "Practical Common Lisp" for Fortran. Some artifact of the different characteristic Fortran user vs the Lisp user maybe?
