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

  1. blinkAllLEDs - Sample which turns on and off LEDs connected to RaspberryPi GPIOs

  2. functions - Sample for go functions

  3. geoLocationSunriseSunset - Sample using go http client to retrieve the lattitude and longitude of a passed location and calculation of the local

  4. gofunc - go functions used to demonstrate the dining philosophers problem using goroutines, channels and mutex

  5. helloWorld - Simple Hello world program

  6. highLow - Simple high/low game on command window level

  7. highLowGameServer - Simple high/low game server using templates and go http server. IBM Bluemix artefacts to deploy the server on bluemix are included

  8. httpsServer - Sample go https server which uses TLS and generates a self signed certificate

  9. interfaces - Sample code which demonstrates go interfaces

  10. ipLocation - Retrieve location information about the current used IP address via REST call sunrise and sunset time via REST calls

  11. loginFritz - Login into an AVM Fritzbox and handle the challenge response. The code retrieves the internet usage counters

  12. methods - Sample go code which demonstrates usage of methods

  13. 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.

  14. types - Samples for the different types in go

  15. utf8 - Sample for utf8 handling in go

  16. 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.
