Our next step in the Raspberry Pi training program is to get zero tiers up and run on a Raspberry Pi 4. How to utilize a Raspberry Pi to measure internet speed and store the results in Grafana or Onedrive was the topic of the last piece. During the project, you will discover how to install ZeroTier on a Raspberry Pi and get it up and running. We will also learn how to set up a firewall to secure our network.

What is zeroTier
ZeroTier is a software that provides a streamlined web-based interface for constructing virtual networks connecting various gadgets. Somewhat akin to configuring a virtual private network on a Raspberry Pi, these networks exist only in cyberspace. The process o ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to use Environment Variables in ASP.NET Core. It's our 5th tutorial in ASP.NET Core series. In our Startup.cs file, you must have seen that we have an IF Condition at the start and this IF Condition has IsDevelopment in it.
This condition is actually checking the environment of our web application. So, here we will first discuss them and then will see why we need them. So, let's get started:
Environment Variables in ASP.NET Core
ASP.NET Core has 3 builtin Environments, which decides the Run-time operating environment of the web application, which are:
Development.
Staging.
Production.
In order to set this Environment Variable, we need to ...
Hello friends, I hope you all are doing great. In today's lecture, we will have a look at the I2C Communication with STM32 Microcontroller board. I am going to use the Nucleo board for today's lecture. In the previous lecture, we have discussed STM32 Serial communication both in Interrupt Mode and polling Mode. Today, we will study another way of communication(i.e. I2C) with STM32. So, let's first have a look at what is I2C Communication:
What is I2C Communication?
I²C (Inter-Integrated Circuit) is a two-wire serial communication system used between integrated circuits. Like any serial protocol, one of its advantages is that of using only two lines that transmit or receive a sequence of bits, the limit is the communication speed which has been improved over the years.
The bus was conceive ...
Hello friends, I hope you all are doing great. Today, I am going to share the second tutorial in ASP.NET MVC series and I will explain the concept of Model in ASP.NET MVC. In our previous tutorial, we have seen How to Setup Your First Project in ASP.NET MVC.
So, before developing our web app, we first have to discuss some concepts in MVC Framework and Model is one of them, which we will cover in today's tutorial. So, let's get started with it:
What is a Model in ASP.NET MVC ?
In, ASP.NET MVC Framework structure, we have to understand 3 very simple blocks, which are:
Models
Controllers
Views
Model connects our web application with our SQL Database, it takes commands from the Controller and then get or set values in the Database an ...
Hey pupils! Welcome to the new tutorial on deep learning, where we are in the section on Python learning. In the previous lecture, we were discussing the tuple data type, which is a sub-class of sequences. In the present lecture, the discussion will be about the byte sequence and byte array. The whole discussion is cleared with the help of practical implementation in TensorFlow by using simple and easy codes. If you understand the concepts of list and tuple, then this lecture will be easy for you. Yet, before going into the details of this topic, you must know the highlights of the content discussed in this lecture:
What is the byte method in Python?
How can you use byte in TensorFlow?
What are some examples of bytes?
Give examples of error handling in bytes.
How can you convert in ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at Form Validation in ASP.NET Core. It's our 15th tutorial in ASP.NET Core series. In our previous lecture, we have created a Registration Form for our engineering website. But we haven't added any validations on the submitted data.
So, even if users don't fill any boxes and just hit the Register Button, a new user will be created without any personal info. So, today we will place some checks on these text boxes to validate the user submitted data. So, let's get started with it:
Form Validation in ASP.NET Core
Validations in ASP.NET Core are available in the form of attributes & Tag Helpers.
Validation Attributes are applied on Properties in Model clas ...
Hey learners! Welcome to another deep learning tutorial, in which we are beginning the practical implementation of Python on the TensorFlow library. We installed and checked TensorFlow in detail while we were in the previous lecture, and today we are going to use it for our practice. We have checked the presence of a perfectly installed library of TensorFlow in our tutorials and seen the basic structure of this library. As a result, we will skip the details and jump right into learning Python. In this tutorial, the main focus will be on Python instead of learning the workings of TensorFlow. You have to remember one thing: all the discussion will be from the point of view of deep learning, and it is not a general tutorial in which you will learn to develop apps or have a discussion about th ...
Hey people! Welcome to another tutorial on Python programming. We hope you are doing great in Python. Python is one of the most popular languages around the globe, and it is not surprising that you are interested in learning about the comparatively complex concepts of Python. In the previous class, our focus was to learn the basics of sets, and we saw the properties of sets in detail with the help of coding examples. We found it useful in many general cases, and in the present lecture, our interest is in the built-in functions that can be used with the sets. Still, before going deep into the topic, it is better to have a glance at the following headings:
What are the built-in functions?
How do we perform the all() function with examples?
What is the difference between any() and all()? ...
Greetings Learners! Welcome to the new lecture on Python. Today we are moving towards an interesting and important concept. If you have come from a programming background, then you must know about the workings of loops. To make the repetition of the same sequence, we use loops. We are familiar with the sequences in detail as we have learned them in the previous lectures and have received the concept in the recent lecture. If you want to be a programmer, then you can not move forward without a solid base of loops; therefore, in this lecture, we will learn the concept of loops from scratch and then go on to a deep understanding of each loop in the next episodes. So have a look at the concepts that you will learn today.
What are the loops?
How do we understand the concept of loops from scra ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to how to print from a Raspberry pi. We also discussed some libraries to create a print server in our raspberry pi. We will learn how to take screenshots on Raspberry Pi using a few different methods in this lesson. We will also look at how to take snapshots on our Raspberry Pi using SSH remotely.
Why should you read this article?
This article will assist you when working with projects that require snapshots for documenting your work, sharing, or generating tutorials.
So, let us begin.
Screenshots are said to be the essential items on the internet today. And if you have seen these screenshots in tutorial videos or even used them in regular commu ...
