Don’t mistake what I’m about to say as being “mean”, it’s just that I truly didn’t know any of this until recently.
Occasionally I’m asked if I “know” MATLAB. My former company had two licenses for MATLAB, and my development machine was one of the two computers with a license installed.
You see, the last guy that owned my work computer was a Ph.D. HE knew MATLAB.
I use KiCAD a lot. KiCAD is love, KiCAD is life.
For me, KiCAD gets the heck out of the way while I get work done.
I’ve recently been writing an RFP, and in the middle of writing it I stopped to think about all the tools I was using.
