I am currently relatively fluent in HTML and CSS. I am trying to become competent in more complex PHP and JS, as I think it is a useful asset to my CV. I am relatively self taught, although using codecademy and w3 schools. I mainly work with hardware, but am trying to get better with software as well. I am having a stab at learning APL but its a little more complicated than first thought, so far i can do this:
X ← 1 2 3 4 5 (+/X)÷⍴X
which outputs 3.
