Re: [Discuss-gnuradio] On tunnel.py

[Andre-John Mas]

Hi,

I just want to add to this. 

In the software community we get to benefit from field experts, people who are 
doing focused research and people who want to explore something new, just 
because they have fun doing it.

This all means we get to benefit from different approaches, which each ending 
up bringing something different to the table. It also why I believe software 
evolution is so much faster than other fields. 

One thing that is nice with gnu-radio, especially today, is the ability to 
explore radio cheaply and without necessarily having an electronics background 
going in. 

Starting small and building up is the way to go.
