use ethernet cable and connect raspberrypi directly
ipconfig : check the new address on the new network
arp -a   : find the neighbour hood, identify raspberrypi ip by exlusion of all broadcast and multicast addresses
use the ip for ssh access
or use ssh raspberrypi.local, if it has a avahi daemon running


(Install PuTTY on windows for ssh client, pftp etc.)

Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.
