Some go sample files for a small go tutorial

All samples can be run on a Raspberry Pi or any other Linux system with one exception: trafficLight uses GPIOs which are available on a Raspberry Pi only.

List of sample code

blinkAllLEDs - Sample which turns on and off LEDs connected to RaspberryPi GPIOs
functions - Sample for go functions
geoLocationSunriseSunset - Sample using go http client to retrieve the lattitude and longitude of a passed location and calculation of the local
gofunc - go functions used to demonstrate the dining philosophers problem using goroutines, channels and mutex
helloWorld - Simple Hello world program
highLow - Simple high/low game on command window level
highLowGameServer - Simple high/low game server using templates and go http server. IBM Bluemix artefacts to deploy the server on bluemix are included
httpsServer - Sample go https server which uses TLS and generates a self signed certificate
interfaces - Sample code which demonstrates go interfaces
ipLocation - Retrieve location information about the current used IP address via REST call sunrise and sunset time via REST calls
loginFritz - Login into an AVM Fritzbox and handle the challenge response. The code retrieves the internet usage counters
methods - Sample go code which demonstrates usage of methods
trafficLight - traffic light simulation of two trafficlights using channels and go routines. Can use real LEDs on a Raspberry using GPIOs and/or simulate LEDs on a monitor. See here a small video.
types - Samples for the different types in go
utf8 - Sample for utf8 handling in go
genSitemap - Sample how to use go lightweight threading (goroutines). Actually it's a remote website crawler which generates a sitemap.xml.

Following information is crawled and reported. The number and URL of
1. valid links to remote wabpages
2. invalid remote links to remote webpages
3. dead links
4. valid links for a sitemap
5. number of crawled pages

This information then is used to compile a sitemap. Used by the author for his websites.
