> Unless you're doing something exotic like that, or have severe performance requirements, or are producing something for very high volume production, working "from scratch" seems pointless. Maybe. Platform limitations are a thing. And you started out your comment with the observation that not everything is a web-app. Way (way!) back in the day, I had to implement SGI's new OpenGL spec on SunOS. Because it didn't exist, and we needed it for some internal semiconductor CAD programs. Which is to say: the CAD program developers had SGIs and the rest of semiconductor design had sun boxes. You might be doing embedded, or robotics, or process control or field-monitoring or flight systems, or ... In many (most?) of those, you make a new directory, fire up vi on a main.c file and go from there. If you are lucky (and luck seems to improve w/ time, I will admit), you have enough headroom (space, performance) to do a lot of it in Python. Often not, though...
