Raspberry Pi - Network Tunnel

I plan to use a number of different web utilites that will require my Raspberry Pi to be available from the Internet. One of the easiest methods that I’ve found is to use “ngrok” to provide a secure tunnel. To expose an http service on a particular port, execute the program with the protocol and port:

ngrok command
1
./ngrok http 1880

This example will allow you to use Node-Red to develop a web service on your Raspberry Pi that can be used as a webhook on an Amazon Echo Alexa skill.

Raspberry Pi - Access to the Filesystem

To make using the Raspberry Pi easier, I installed a couple of utilities. I enabled VNC access so that I can open the Raspberry Pi’s GUI from my MacBook and I also want to be able to access the Pi’s filesystem directly.

Backup a Raspberry Pi

I’ve started using a Raspberry Pi 3 to learn some new technologies. I want to be able to backup the files from the SD card used by the system because I don’t want to lose the configure and startup files and have to start from scratch if something goes awry.

JavaScript30

I just completed the first project in the #JavaScript30 training course offered by Wes Bos. He provides free access to 30 videos, starter files, and assets to “build 30 things in 30 days with 30 tutorials” using nothing but plain JavaScript. In the first project, he walks you through building a “drum kit” in your browser. Since most of my HTML/JavaScript experience is with line of business apps in a corporate setting, I had never used the audio HTML tag before. I enjoyed Wes’ presentation style and he may very well end up with another paying customer for his other courses.

The “drum kit” was a fun project and I’m looking forward to working on the other 29. Wonder what’s next???

Hosting a Static Site on Github

I was talking with a friend today about working on my blog this weekend and how it was hosted on Github using Github Pages. I told him that I would send him an e-mail with info on how to setup a site and I decided instead to create this post to document the steps I took. Hopefully it may help others who are attempting to do the same thing.

Re-creating a Hexo Web Site

I recently discovered that the files I need to create a post on this site had been lost. Not only that, but pulling down the repo from my bitbucket repo didn’t help. Some of the critical files were not stored in the repo. So, I’ve spent most of this weekend recreating the site and I took notes of the process and included some documentation to help with maintaining a Hexo site.
