How to setup Raspbian Jessie Lite on Raspberry Pi 3 to run Python 3 applications

The Raspbian operating system is the Raspberry Pi Foundation’s official supported operating system. As of this writing, Raspbian comes in two flavours – one with a graphical user interface for us to build a low cost desktop computer and the other without the graphical user interface.

If you intend to use your Raspberry Pi 3 with sensors and build a web interface for you to manage those sensors, Raspbian Jessie Lite is one operating system which you may want to install on your Raspberry Pi 3.

And with the versatility of Python 3, setting up Raspbian Jessie Lite on Raspberry Pi 3 to run Python 3 applications will be one of the first task that you will perform before you embark on your next sensor based project with the Raspberry Pi 3.

This post documents the steps that I took to setup Raspbian Jessie Lite on Raspberry Pi 3 to run Python 3 applications.

How to host your Python 3 Flask MVP with Supervisor on Ubuntu Server 16.04

Due to its minimalistic design, the Python Flask framework is ideal for building the web server layer of minimal viable products (MVP) to validate customers’ needs. However, development work is just one part of the user validation efforts. To ensure that our customer can access our Flask MVP and provide feedback as and when they are available, we will need to get it running with as a server daemon.

Supervisor is a convenient tool for running applications as a server daemon.

This post documents the steps that I took to host a Python 3 Flask MVP with Supervisor on an Ubuntu Server 16.04 instance.

How to setup Ubuntu Classic Server 16.04 on Raspberry Pi 3 for running Python 3 applications

Most of the customers who wanted to try out my minimal viable products (MVP) would provide me with an instance of Ubuntu Classic Server 16.0x these days. As such, it makes sense for me to trial my MVPs on the Ubuntu Classic Server 16.0x to ensure that I spend minimal time in deploying my MVPs to validate my customers’ needs. Since I have a few Raspberry Pi 3s lying around in the house, I can install a version of Ubuntu Classic Server 16.0x to serve as the development server for me to trial my MVPs.

Fortunately, the good folks at ubuntu-pi-flavour-maker.org had put up an optimised Ubuntu Classic Server 16.04 image for Raspberry Pi 3.

This post documents the steps that I took to run Ubuntu Classic Server 16.04 on my Raspberry Pi 3 for running Python 3 applications.

Installing Octave on my MacBook via Homebrew

Andrew Ng’s Machine Learning course on Coursera brought about the need for me to install Octave on my MacBook. Since I had only two days before I could submit my first Octave assignment without any penalty, I decided to use the simplest method to get Octave running on my MacBook.

This post documents the steps that I took to install Octave on my MacBook via Homebrew.

How I setup Codiad web IDE on my Raspberry Pi 3 with Ubuntu Server 15.10.3, Nginx and PHP

There are times when I get the urge to work on project source codes that reside on my Raspberry Pi 3 LEMP server while I am on the move. Setting up a web based IDE on my Raspberry Pi 3 is one way to enable me to code while I am on the move, so long as I have a device with a web browser that is connected to the internet. Since I had already setup a LEMP server to run WordPress on my Raspberry Pi 3 and that Codiad is written in PHP, Codiad is an ideal web based IDE that I can set up on my Raspberry Pi 3.

This post documents how I setup Codiad web IDE on my Raspberry Pi 3. To make this post complete, I had taken some of the steps mentioned in my other posts on Raspberry Pi and replicated it in this post.

How to prepare the operating system to run your Raspberry Pi, with your Windows machine

Recently, I had been deploying several pieces of Raspberry Pi around my house for different purposes. In order to use Raspberry Pi as a TV Box, a CCTV, a LEMP server or any other appliances, we will need to prepare an operating system in a microSD card to run our Raspberry Pi.

I always use my Windows machine to prepare the operating system for all my Raspberry Pis, since I find that it is easiest to write an operating system for Raspberry Pi on a Windows machine. This post documents how I would prepare the operating system to run my Raspberry Pi with my Windows machine.

Setting up Nginx server on Windows 10

Recently, I got my wife an Asus ROG GL552VW-DH74 15-Inch Gaming laptop as a development machine (so that I can have a machine to use when I feel like gaming). Since the nginx server is one of my favorite servers for building web applications, it is something that I will always setup first when I get a new development machine.

I will set up my nginx server to listen on port 80 and serve as a reverse proxy to web applications listening on other port numbers. And since the ROG GL552VW-DH74 15-Inch Gaming laptop came with Windows 10, this post documents the steps that I went through to set up nginx server on Windows 10.
