How to send an HTTP request to a HTTP Basic Authentication endpoint in Python 3 with requests library

When you are building a Python 3 application for the Internet, you could encounter API endpoints that use HTTP Basic Authentication as the authentication mechanism.

In such a situation, using the requests library in your Python 3 code makes it easier to communicate with those endpoints.

In case you need to build a Python 3 application that sends HTTP request to a HTTP Basic Authentication endpoint, this is how you can do so with the requests library.

How to create a Python 3 virtual environment in Windows 10

When you need each Python 3 application that you are building to run in its own isolated environment, you can turn to virtual environments.

Since Python 3 is a versatile language, you can run it on Windows 10 as well.

In case you need to run your Python 3 application in its own virtual environment in Windows 10, this post is for you.

How to download a file via HTTP POST and HTTP GET with Python 3 requests library

When you are building a HTTP client with Python 3, you could be coding it to upload a file to a HTTP server or download a file from a HTTP server.

Previously, we discussed how to upload a file and some data through HTTP multipart in Python 3 using the requests library. In this post, let’s see how we can download a file via HTTP POST and HTTP GET.

How to determine if your Windows 10 IOT operating system is 32 bit or 64 bit

Before installing anything to the version of Windows 10 IOT operating system on your device, you will need to figure out whether it is 32 bit or 64 bit.

In case you need it, this post shows how to determine whether your Windows 10 is 32 bit or 64 bit.

Enabling ESP8266 Development on Arduino IDE

Undeniably, the ESP8266 NodeMCU LUA Development Board is cost efficient for IOT solutions. Available at a low price point and built-in WiFi, we can easily get sensor readings and make them available on the Internet.

In order to run our program on ESP8266 NodeMCU LUA Development Board, we will need to write our program into the flash memory of the development board. Since it is easy to write code and flash programs with Arduino IDE, it is a good tool to use with the ESP8266 NodeMCU LUA Development Board.

In case you are looking for a reference to enable ESP8266 development on Arduino IDE, this post shows how you can do so.

How to install python3-venv on Ubuntu 16.04

Since Ubuntu 16.04 is a very popular operating system, it is one operating system that you will likely come across when you are building software with Python 3. For example, if you want to get a Nvidia Jetson TX2 developer kit today, you will find yourself dabbling with Ubuntu 16.04.

On the other hand, the venv module of Python 3 is one recommended way to create virtual environments for our Python 3 projects.

In case you need it, this post describes how to install python3-venv on Ubuntu 16.04.

How to host a static website on your Raspberry Pi 3 with Raspbian Stretch Lite and Nginx

When you want to host a static website as your personal portfolio, you can consider using a Raspberry Pi 3. In addition to having a small form factor, a Raspberry Pi 3 is a single board computer that does not take up too much energy to run 24-7.

In order to host a static website on Raspberry Pi 3, you will need an operating system and a web server. Given these points, this is how to host a static website on your Raspberry Pi 3 with Raspbian Stretch Lite as the operating system and Nginx as the web server.

How to use Flask-APScheduler in your Python 3 Flask application to run multiple tasks in parallel, from a single HTTP request

When you build an API endpoint that serves HTTP requests to work on long-running tasks, consider using a scheduler. Instead of holding up a HTTP client until a task is completed, you can return an identifier for the client to query the task status later. In the meantime, your HTTP server can offload the task to a scheduler which will complete it and update the status.

When you are building your HTTP server with Python 3 Flask, Flask-APScheduler gives you the facilities to schedule tasks to be executed in the background.

In this post, we look at how we can get Flask-APScheduler to run multiple tasks in parallel, from a single HTTP request.

How to use Java to check whether a domain exists without any external libraries

You wanted to buy a domain for your personal website. You found a whois service and it told you that your domain is available. You are elated and tried to acquire the domain through your favourite registrar. However, your registrar told you that the domain had already been taken.

Isn’t that frustrating? Well, it happened to me once and I was determined never to use the whois service of those unscrupulous sites ever again.

So how can you check whether a domain name is available by yourself? When you have a computer at hand, you can find several ways to do so. In this post, I share how you can check whether a domain exists with the Java programming without using any external libraries.
