What is the size of this list?

Hi people,

I am a lurker (I think), I am an embedded programmer and work at
Lowrance (a brand of the Navico company), and I don't think I can't
provide too much to security because embedded software is closed per se.
Or maybe I am wrong, is there a way to grab the source code from an
electronic equipment? That would be the only concern for embedded
programmers like me, but I just like to learn about the thinks you talk.

Thank you.

Greetings from Mexico.
