Different ways to enable SSH server on Raspbian Stretch

When you have an SSH server running on your operating system, you will be able configure it remotely. Since the SSH server is such a convenient tool, Raspbian Stretch comes with an SSH server.

When you are looking for a way to configure your Raspberry Pi without attaching a keyboard to it, enabling SSH server on Raspbian Stretch is a viable way.

Given that, this post discusses some ways for us to enable SSH server on Raspbian Stretch.

How to setup Raspbian Stretch on Raspberry Pi 3 for developing Python 3 applications

Previously, I had shared:

Although Raspbian Stretch Lite is ideal for running Python 3 applications on Raspberry Pis, it is not so handy for developing Python 3 applications.

For example, if you are building a Python application that interfaces with the GPIO ports and CSI camera of your Raspberry Pi 3, it is hard to test it out on Raspbian Stretch Lite.

Since Raspbian Stretch includes a desktop environment, it is more convenient for developing Python 3 applications for Raspberry Pi. With this purpose in mind, this is how to setup Raspbian Stretch on Raspberry Pi 3 for developing Python 3 applications.

How to create a virtual environment for your Python 3 application with python3-venv in Linux or Unix

The python3-venv module allows us to create lightweight “virtual environments” with their own site directories, optionally isolated from system site directories. Given that, we will be able to run multiple Python 3 environments with varying dependencies on the same computer.

This post shows how to create a virtual environment for your Python 3 application with python3-venv in Linux or Unix.

How to make your Raspberry Pi fill up your entire monitor screen by disabling overscan in Raspbian Stretch

After you had booted up Raspbian Stretch for the first time, you may notice that your Raspberry Pi does not fill up your entire monitor screen:

Raspbian Stretch 20181113 not filling entire computer screen

In such a situation, the overscan function in Raspbian could be what you should disable. Given that, this post shows how to make your Raspberry Pi fill up your entire monitor screen by disabling overscan in Raspbian Stretch.

How to download a file via HTTP GET and HTTP POST in Java without using any external libraries

Apart from uploading a file to a HTTP server endpoint, another common task for a Java HTTP client is to download a file from a HTTP server. Even though there are many Java external libraries to help us do so, using the facilities in the Java standard runtime installation is not difficult. Furthermore, we will be able to keep our Java application leaner if we can download files without additional dependencies.

In case you need a reference, this is how to download a file via HTTP GET and HTTP POST in Java without using any external libraries.

How to setup Jupyter Notebook on Ubuntu 16.04 of your Nvidia Jetson TX2 developer kit

When you want to quickly test out your machine learning algorithm, you can create Python 3 notebooks via Jupyter Notebook.

Therefore, Jupyter Notebook is one of the things that you may want to setup after getting started with your Nvidia Jetson TX2 developer kit.

With this in mind, this post shows how to setup Jupyter Notebook on Ubuntu 16.04 of your Nvidia Jetson TX2 developer kit.

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.
