A Raspberry Pi is one of the things that you should consider getting if you are a computer programmer.

Just bought a Raspberry Pi but not sure what to do with it? If that is the case, you had come to the right place. On this page, you will find plenty of ideas on how to use your Raspberry Pi.

By following the ideas here, you will understand your Raspberry Pi and the Linux operating system better. In addition, you will be able to setup your Raspberry Pi to serve some interesting use cases at home.

For example, you will find instructions on how to setup a CCTV for surveillance, Web IDE to help you code everywhere you go, project management platform for tracking your project statuses and etc.

How to start a blog about computer technology

Previously, I wrote about why programmers should blog. When you are convinced that you should blog as a programmer, you may wonder how to start a blog.

In order to have a place to refer people who wants to learn more about this topic, I write my experience in this article.

Given that in mind, this is how you can start a blog about computer technology.

How to prepare a virtual environment to run a gpiozero based project on Raspbian Stretch

When you use a virtual environment to run your application, you isolate the dependencies in its own container.

In such a situation, you can ensure that your application can run alongside other applications with incompatible dependencies.

Therefore, I always favour the use of virtual environment for running my Python applications.

With this in mind, this is a story about preparing a virtual environment to run a gpiozero based project on Raspbian Stretch.

How to host a static website on your Raspberry Pi Zero W with Raspbian Stretch Lite and Nginx web server

After you capture the Northern Lights with an entry level DSLR, you may want include them in your personal portfolio. Until you find the time to setup a content management system for your personal portfolio, you want to keep it as a static website.

At this point in time, you saw that Raspberry Pi Zero W and cover lying on the table. In addition to that, you have a spare micro USB charger that you used for charging your old Android phone.

Since you do not have any other use for these items, you decided to host your personal portfolio on that Raspberry Pi Zero W.

With this intention, this is how you can host a static website on your Raspberry Pi Zero W with Raspbian Stretch Lite and Nginx web server.

How to setup a Raspberry Pi web server with Raspbian Stretch Lite, Nginx, MariaDB and PHP as the LEMP stack

Raspberry Pi LEMP Linux Nginx MariaDB PHP

When you want to deploy a PHP application that you wrote, you can first deploy it on a Raspberry Pi. Once your PHP application gets enough traction, you can then port it over to a computer with more horsepower.

When your PHP application employs MySQL or MariaDB as the backing database, we can put it up on a LEMP stack. In this situation, HTTP requests will first be directed to the Nginx reverse proxy server. Whenever the request is made to a php application, Nginx will then pass it on to the PHP7 Fast CGI Process Manager (PHP FPM) for generating the HTTP response.

Given these points, this post provides the steps to setup a Raspberry Pi web server with Raspbian Stretch Lite, Nginx, MariaDB and PHP as the LEMP stack.

How to enable VNC server on Raspbian Stretch with raspi-config

When you have a VNC server enabled on your Raspbian Stretch, you will be able to access your Raspberry Pi from another computer. Furthermore, you will be able to use your Raspberry Pi from a graphical user interface.

Therefore, if you want to enable SSH server on your Raspbian Stretch but is not really comfortable with a command line interface, a VNC server is what you should enable instead.

In such a situation, you can use raspi-config to enable VNC server on Raspbian Stretch. Let see how we can do so.

How to configure locale settings of Raspbian Stretch with raspi-config

Locales are a framework to switch between multiple languages and allow users to use their language, country, characters, collation order and etc. Therefore, it is an important setting to configure before using your Raspberry Pi.

Given that, let us look at how we can configure locale settings of Raspbian Stretch with raspi-config.

How to connect your Raspberry Pi to a WiFi network with raspi-config in Raspbian Stretch

When you own a Raspberry Pi with in-built WiFi or an attached USB WiFi adapter, you will be able to connect it to a WiFi network.

Given that WiFi connectivity, you can use then your Raspberry Pi as a HTTP server and/or a HTTP client on the Internet without using a network cable.

When you have installed Raspbian Stretch on your Raspberry Pi, you can use raspi-config to connect your Raspberry Pi to a WiFi network. For this purpose, you can follow the steps mentioned in this post.

How to change the hostname of your Raspberry Pi via raspi-config in Raspbian Stretch

When you install Raspbian Stretch as the operating system for your Raspberry Pi, the default hostname is raspberrypi.

Since a Raspberry Pi is one of the things that programmers buy, we could deploy several at home.

When you have several Raspberry Pis deployed in your house, you may want them to be identified by hostnames.

So how can we change the hostname of our Raspberry Pi running Raspbian Stretch? This post shows how you can change the hostname of your Raspberry Pi via raspi-config in Raspbian Stretch.
