Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Increase EF Core Performance for Saving Multiple Entities? EF Core works well for simple CRUD operations but for saving multiple entities EF Core provides poor performance. So, today we will use a third-party EF Core extension named "Z.EntityFramework.Extensions.EFCore", designed by ZZZ Projects, which will increase the EF Core performance significantly. I will be using a BulkSaveChanges Method of this library which is specifically designed for saving bulk data in an SQL database.
ZZZ Projects is a trusted company and has designed numerous .NET libraries, a few having downloads in millions. So, you can completely trust this extension library.

Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at How to Create a New Model in ASP.NET MVC. It's 5th tutorial in ASP MVC series. We have already seen the basic concept of Model in ASP.NET MVC in our second tutorial. Models are used to communicate data from SQL Database to respective Controllers, which is then displayed by the Views to the user.
When you are designing some professional website then it happens a lot that you need to place different data in your databases, normally this data is coming from users. So, in such cases you have to create new models and then assign respective controllers to them. So, today we will see How to do the first ...
Hey peeps! Welcome to an exciting tutorial on Python in which you will learn about the Python reverse list. We are on a series of deep learning phases where Python is under our observation. In the last tutorial, we saw the variables in Python and practised many codes in the TensorFlow. Today, we are interested to practice many interesting methods in an easy way. These are the built-in functions and you do not have to be an expert in the programming to perform them in TensorFlow. All you need is to read this tutorial and have the TensorFlow working fine. Before going deep into the topic, it is important to have a look at the list of content that you will learn today:
How do you define the python reverse list?
Why we should know about the python reverse list or keywords?
How do you practi ...
Hello learners! Welcome to the next episode of the arrays, in which we are moving towards the details of the arrays at an advanced level. In the previous lecture, we covered the introductions and fundamentals of arrays, dimensional arrays, and array operations. One must know that the working of the arrays does not end with simple operations, and there is a lot to learn about them. Arrays and their types are important topics in programming, and if we talk about Python, the working and concepts of the array in Python are relatively simple and more effective. The details of the advanced types of arrays will prove this statement. We have a lot of data to share with you, and for this reason, we have arranged this lecture. It is important to understand the reasons behind the reading of this lect ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to start this new series on ASP.NET MVC Framework. I am gonna start from basics and will slowly move towards professional projects. I will share all the codes during this series and if you got into any trouble then ask in comments and I will help you out.
One of our Team Member has already designed videos on ASP.NET MVC and I will keep on embedding the respective videos throughout this tutorial series. In our first tutorial, we are gonna have a look at How to Setup your First Project in ASP.NET MVC Framework. So, let's get started with it:
Setup your First Project
I will use Microsoft Visual Studio 2015 and I hope that you have already installed it.
If you are usin ...
Greeting, and welcome to the next tutorial of our raspberry programming tutorial. In the previous tutorial, we learned how to build a smart attendance system using an RFID card reader, which we used to sign in students in attendance in a class. When it comes to building a face-recognition program on a Raspberry Pi, this tutorial will show you how. Two Python programs will be used in the lesson, one of which is a Training program that analyzes a collection of photographs of a certain individual and generates a dataset. (YML File). The Recognizer application uses the YML script to detect a face and afterward utters the person's name when the face is detected.

Introduction
Thank you for joining us for yet another session of this series on Raspberry Pi programming. In the preceding tutorial, a facial recognition system on a Raspberry Pi 4 was used to develop a smart security system. We also learned how to create a dataset using two Python scripts to train and analyze a series of photographs of a certain person. This tutorial will teach you how to install pi-hole on a Raspberry Pi 4 and use it to block advertisements from anywhere. This is a great initiative for folks who are tired of annoying pop-up adverts while browsing. First, we'll learn how to set up the pi-hole without the need for an environment, then we'll use Docker to install pi-hole, and ultimately we'll see how we can access it from anywhere.

Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Create ViewModels in ASP.NET Core. It's our 9th tutorial in ASP.Net Core series. We have already covered Controllers, Models & Views in our previous lectures and now it's time to understand this fourth pillar of MVC architecture.
ViewModel is not an integral part of MVC architecture and can be ignored in simple projects but in complex applications, we have to use ViewModel as it adds flexibility in the project. So, let's have a look at ViewModels in ASP.NET Core:
ViewModels in ASP.NET Core
ViewModels in ASP.NET Core ( also called Data Transfer Objects [DTO] ) are used to send Models data from Controll ...

We're glad you could join us for another lesson in our series on programming for the Raspberry Pi 4. The previous chapter covered how to interface the USB barcode scanner with raspberry pi 4. We looked at different types of barcodes and what each stripe represents as well as the different types of barcode scanners available today. We also built a python program for the intelligent shopping cart and now our familiarity with barcodes and scanners and how they function has significantly increased. The benefits and drawbacks of its use were also discussed, but what we're interested in for this article is the transmission of radio frequency signals using the nrf24l01 Module in a raspberry pi 4.

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.
Components
Raspberry pi 4

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 ...
