How to use Namecheap DynDNS service with ddclient on the Raspberry Pi

Log into your Raspberry Pi (by ssh for example) or open a terminal window if you are working directly on Pi. In the first step we have to install ddclient, a DynDNS software, on the Pi. For this purpose, the following two commands are necessary.

sudo apt-get update
sudo apt-get install ddclient

Note: During installation an installation wizard opens and wants to know some things from you. Here you can safely enter what you want, because we have to adjust the configuration file manually either way, because the wizard does not support the Namecheap.com interface.

INTRO

Concurrency is a domain I have wanted to explore for a long time because the locks and the race conditions have always intimidated me. I recall somebody suggesting concurrency patterns in golang because they said "you share the data and not the variables".

Amused by that, I searched for "concurrency in golang" and bumped into this awesome slide by Rob Pike: https://talks.golang.org/2012/waza.slide#1 which does a great job of explaining channels, concurrency patterns and a mini-architecture of load-balancer (also explains the above one-liner).

Let's dig in:

Goroutines

func listen(end chan<- bool) {

sudo apt-get install connman

After connman was successfully installed trying to scan wifi you will get:

connmanctl> enable wifi
Enabled wifi
connmanctl> scan wifi
Error /net/connman/technology/wifi: No carrier.

Solution is remove wpa_supplicant.conf

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
