(Detailed Guide)

AirTag is a tiny gadget that can track your losing items. Once you attach the AirTag to the items like Keys or Bags, you can easily track its location. For instance, if you ever left your essential items somewhere, you can open your iPhone and find its location without breaking a sweat.

Since it is the latest product in Apple’s lineup, many users are unaware of what AirTag is. But, how it works is even more interesting.

In this article we will first discuss what AirTag is and how it works. Then after, we will see how we can use AirTag and finish up with some of its applications.

AirTag is made up of plastic and stainless steel back and is just 1.26Inch diameter. You can remove the stainless steel back by applying pressure and rotating counterclockwise.

Once you remove it, you will find a replaceable coin cell battery that will give power to AirTag that can run for over 12 months.

It’s a rare product in Apple’s lineup with a replaceable battery. But you can’t charge it. You only need to replace it with a new one once it dies. 

There’s more important technology inside this tiny gadget you can’t see, such as a speaker, Bluetooth, and U1 chip. So, with the interconnection of such components and the help of iOS devices and Find My app you can find your or someone else’s lost items.

To understand how exactly AirTag works and how to connect AirTag with other devices follow along this article.

Connecting AirTag is as simple as connecting your AirPods. But, before you connect, you should know and enable a couple of things on your iPhone.

Ensure your iOS version is running 14.5 or later.

Two-Factor Authentication must be turned on.

Find My and Bluetooth Settings also need to be enabled.

Your iPhone must be connected to the Internet using Wi-Fi or Cellular data.

If you have more than one AirTag, you must set them up one at a time.

Once you are clear about these things, now let’s connect your AirTag to the iPhone.

Now, let’s find out how AirTag works once you finish setting up all the device. Try to play a sound, and AirTag will give you a sound that gives you an idea of its location. You can follow the sound and find your item. But, there’s an interesting way to locate such a lost item called Precision finding.

When writing this article, this precision-finding feature only works for iPhone 11 and higher. The precision finding is handy if the item is lost within 50 feet. Follow the below steps to use this functionality.  

Let’s imagine a scenario where you lose your items. Let’s say you left the bag in the middle of nowhere, but fortunately you have attached the AirTag within it. Now, in such a scenario, AirTag really shines. 

You can simply put it into Lost Mode, which will use Find My app and nearby iPhones to locate your lost items. It sends a Bluetooth signal through other people’s iOS devices that happen to be within range and will report to you. This is a safe, anonymous, and encrypted transmission without letting other people know. 

Also, it doesn’t affect other people’s battery life or data usage. When the closest iPhone device passes by, it will keep updating your device for the latest location. Luckily, iPhones are everywhere that constantly help you find your lost AirTag.

However, it also depends on the region where you live. Suppose you are in a region where there are not many people who use iPhones. AirTag might struggle to work in that case. 

To find your AirTag using Lost Mode, you need to enable it first. Follow the given steps below to enable it.

As mentioned above, only nearby iOS devices can locate the Lost items. However, in the case of lost and found, Android users can also help find the AirTag.

For instance, if you are an Android user and your Phone supports Near Field Communication (NFC), you can contribute to returning the lost item to the original AirTag owner by simply scanning the back of your android phone. 

It will pop up on the website and give the necessary information about the owner details like Phone number and the message displayed on the AirTag. You can call or text that number to return their items. It’s a great way to help someone.

On iPhone

On Android

AirTag is one of a kind gadget, but it’s a blessing and curse. It can be very useful to track your essential items. However, there’s a catch. People with bad intentions can use this gadget to stalk or track you wherever you go or live.

If you think someone is tracking you, they put an AirTag on your purse or attach it to your car. It can be a serious threat if you are not aware of it. Thankfully, there’s a solution for that. 

If the AirTag has been traveling close to you after leaving its AirTag owner for 10 minutes or more. Eventually, you will be notified with a notification saying an unknown AirTag is moving with you.

Tap the notification and see where the AirTag was detected near your device. To get Notifications on time, ensure to enable Find My app notification (from device settings) and Items Safety Alert (from Find My app) to keep you updated. 

If you receive a notification that says AirTag Found Moving with you, follow the given instructions to deal with it:

If you want to verify the nearby AirTag, follow the given instructions:

How Does Laravel Find Work?

Introduction to Laravel Find

Web development, programming languages, Software testing & others

What is Laravel Find?

With the help of the primary key that is present in Laravel, it helps in retrieving a single record of data from the database that is available for purpose of the functioning of the application to be processed. The key in the array is not used by the find option. It is also not intended to be a column name. The user needs to understand that eloquent is not the shortcut but find is.

When there is a need to retrieve any record with the help of the primary key use this code:

$user = User::find (1);

The find() method finds the Model by its $primaryKey property. If you have none set, it’s going to assume id. If you have something set up like protected $primaryKey = foo_id the find() function will go through foo_id instead of id. Laravel also expects the id to be an integer; if you are using something other than an integer (such as a string) you need to set the incrementing property on your model to false.

How does Laravel Find work?

Laravel find is capable of retrieving data from the database for the user when the user needs to obtain a concerned set of data from a larger database. With a load of too much data, it becomes difficult or even time-consuming to manually hunt for a specific set of records to work on. Most of the data in Laravel are auto-generated and they are self-coded as Laravel PHP helps in getting applications and websites ready faster with a lot of automated properties. Laravel Find is used to retrieve data with the help of primary keys that are available in Laravel. One thing that any user will have to note is that Laravel find is not a query builder as it may look to be. This misunderstanding needs to be clarified in priority.

The query builder that is available in Laravel provides a lot of conveniences. It also gives an interface to create and run the queries of the database. Most of the database operations can be performed in the application that is customized and prepared. It also works on all supported database systems.

The above example will help us to understand the working of Laravel Find better.

In the above image, id is ‘1’ and is having data records to be retrieved of the ‘kids’ section with the description as ‘items that are meant for kids’, The other details of time are represented as ‘null’ which means they are not available in the database with the help of Laravel Find.

Unlike ‘Where’ that helps you to get any valid database field, find is using only the primary key that is registered by default in the system to retrieve single data from the database. ‘Where’ uses the ‘get’ method in which you will get more than a single result as it does deep searching and responds with many similar kinds of data in response.

With the help of the ‘find’ method as seen in the above image when the user retrieves information, the user is bound to get an object if the record actually exists in the database. The object that will be received will be the instance of the ‘Model’ and all the database fields that are available will be made available as attributes as that of the class. In response to no data being found inside the database, the response is directly ‘null’ value.

The above image describes the use of ‘where’ model to retrieve data from the database. There can be a limit that the user can establish while using ‘where’ clause by limiting the results to a single row with the help of the ‘first’ method on the instance variable like this:

This first method responds as similar to the ‘find’ method in order to retrieve data from the database. Laravel find thereafter will search for the records from the database that will match the filter criteria that are presented by the user by using the given option but it will only return the first and primary record that will match the search criteria of the user.

Example to Implement Laravel Find

As we know, the find () method in Laravel can be used by any user along with an array of primary keys, and it will return a set of matching records from the database. For example,

$student = Students::all ();

With the help of the above data, we can get the details of all the students.

$student = Students::find (1);

The above code will help us to retrieve the data of one student recognized by ‘id’.

As we see, with a specific attribute we can find the details of a particular student.

Conclusion

As we come to understand, Laravel Find is used to get a single data from the data. Laravel find will look for specific data with the help of the primary keys. Unlike ‘Where’ through which similar data from the database is also retrieved for the user, ‘find’ looks for specific data. If the data is not available, it will present the ‘null’ value.

How Does Java Microservices Work?

Introduction to Java Microservices

Microservices are nothing but a set of applications written in Java language, or we can say that they are typically Java tools and frameworks. Developers usually design microservices for a specified scope and interact with each other with high availability. Each microservice has limited capabilities while we are creating the architecture. The microservice architecture is analogous, so we must assemble it for the desired result.

Start Your Free Software Development Course

Key Takeaways

It is a small Java application, so each microservice is independent.

It collaborates with the agile process, so we can do a fast sprint iteration and try to fix the bugs.

It also helps us to reduce the cost due to the agile process.

It provides scalability architectures to the developer.

What are Java Microservices?

Java microservices are a group of programming applications written in the Java programming language (and regularly influence the huge useful system of different Java tools and frameworks), intended for a restricted scope that works with one another to shape a greater arrangement. As the name infers, every microservice has negligible capacities for modularity, generally creating modules or architecture. A microservices design resembles an assembling sequential construction system, where every microservice resembles a station in the mechanical production system.

How do Java Microservices Work?

Before going on to the execution, we must know what microservices is. We have already discussed the above point. We understand that each microservice performs a specific task with a limited scope, contributing to effectively achieving the desired results.

Java Microservices Frameworks

Different Java-based frameworks are available for creating Java microservices, so let’s see them one by one as follows.

Spring Boot: It is the most popular framework used to create microservices, or we can say that Java application due to simplification, easy configuration, and security application. With this framework, we can create microservices easily and iterate fast; this is one of the reasons for spring boot.

Jersey: This is another Java-based framework that is used for creating microservices. It is used for the REST web services, and this is one of the communication layers between the microservices.

Swagger: This is used to create APIs; it is also a Java base, one of the communication layers between the microservices.

The Architecture of Java Microservices

Microservices provide independent space to the developer and administration to build microservices design as per our requirement. A variation of primary style design orchestrates applications as an inexactly coupled help assortment. Microservice Engineering contains fine-grained administrations and lightweight conventions. Developers design microservices to address specific application requirements individually, and they communicate with each other to collectively generate the final result sets.

Let’s see an e-commerce application:

Benefits of Java Microservices

We know that microservices is nothing but a small-scale Java application, and it is based on the problem domain, which we need to implement as well. It also helps us follow the agile process, so they can do fast iteration and determine the new features within the specified schedule.

It helps the developer resolve bugs immediately, minimizing costs and fewer bugs.

Microservices are small applications, so they communicate with each other. That means microservices are independent, and the most important benefit is that developers can use any programming language to develop microservice.

Example of Java Microservices

In the above point, we can see how to use microservices with different frameworks, so here, let’s see an example with spring boot as follows.

Code:

import org.springframework.boot.*; import org.springframework.boot.autoconfigure.*; import org.springframework.stereotype.*; import org.springframework.web.bind.annotation.*; @RestController @EnableAutoConfiguration public class sampledemo { @RequestMapping("/") String index() { return "Sample demo project will be done"; } public static void main(String[] args) { SpringApplication.run(sampledemo.class, args); } }

Output:

In the above code, we try to implement the microservice in spring boot; the result is shown in the below screenshot.

FAQ

Given below are the FAQs:

Q1. Is Java suitable for microservices?

Answer: The answer is yes because Java is the most popular programming language, and we can easily develop microservices in Java. Java provides the annotation syntax to the developer.

Q2. How and what types of microservices are present in Java?

Answer: There are 3 different types of microservices, such as discovery server, authentication service, and consumer microservice, used for the client.

Q3. Which is the best framework for microservices implementation?

Answer: There are different types of frameworks available to implement microservices, such as spring boot, quarks, eclipse, and Ballerina.

Conclusion

In this article, we saw what Java microservices are, as well as we also saw some basic key ideas of Java microservices with configuration. We also saw the uses and features and how we can use them.

How Does Angelscript Work With Example

Introduction of AngelScript

Start Your Free Software Development Course

Web development, programming languages, Software testing & others

Why do we Need AngelScript?

AngelScript is needful because it is a powerful object-oriented scripting language like c/c++. It has an extremely flexible cross-platform scripting library; hence the scripts or a computer program written can work on any platform, and the scripting library is designed to improve the functionality of the script; by using it, users can extend the functionality with the help of external scripts.

It also has a feature that we can call the c and c++ functions within the angel-script environment; due to that, it is helpful to the developers to work with it, and the syntax of the angel-script class was closely followed by the syntax in c++ classes. So that it is needful for developers who are worked with c++ and they have to work on angel-script, then they can work easily.

Angelscript can be used in robotics that means the behavior rules of robotic are followed by angel-script. Also, it is useful for video game development, which increases the life of a game. So by using angle-script, get the project up, and that will run faster. And by using an external script, we can improve the functionality of the application.

How does AngelScript Work?

First, we need the application of angel-script and then have to register the interface so that script can interact with the application; the interface contains functions, variables, and classes also.

Secondly, we have to set message call back to receive information about errors, errors in human-readable form, because if the registration is not done correctly, then attention message will get as a callback message about the incorrect registration or a script has an error that fails to compile. If we need to verify the return code, there is no need to take much effort to know it because the call-back message can give information in the human-readable form so that we can correct it. These two steps are about engine configuration.

After engine configuration next step is to compile the script that should be executed. Also, need to write a function to call the registered print function and will give the output that function is stored in files.

In this step, has to write code for loading script files and to compile it, there is a CSriptbuilder define it, which help to load the file, it will perform some necessary process, and it will tell the engine to build a script module, also need to construct builder code for processing. If the code fails after this, then it will not have the memory to allocate the module. If the filename has been removed or the wrong name was given, or there is some unnecessary code has been written, then the builder was not able to load the file.

The last step is to identify the function which was defined that is to be called and have to set up the context for execution in code format. If that function could not be found, then need to write a print function to show a message of the function expecting.

Then has to create context, prepare it, and then execute it; if the execution didn’t work as expected, there is a need to write an exception code to handle the exception.

Example of AngelScript

Below is a very simple example that will give a brief overview of Handle:

}

Advantages

It has features like c/c++ that is static-typing, that uses the same static type as we use in c/c++ to make typing dynamic, and only additional type that we need to register here in angel-script.

It has an object handle feature that provides pointers, but pointers are not safe in scripting; hence it uses object handles instead of pointers; object handles in scripting control the lifetime of the object.

It has mod support in-game logic where it increases the life of the game.

Angelscript supports native calling conventions on major platforms, but there are some platforms that only work with generic calling conventions; generic calling is pure C++ that works everywhere.

The CScriptString used in angel-script cannot return the object value in native mode, which is not compatible.

There may be a memory leak issue.

Conclusion

In this article, we conclude that it is a scripting language and that has information about the application to accurately communicate with the c/c++ code; it has an inbuilt library hence making scripting language in our project is easy; in this article, we have seen some reasons to develop our program in more than one language.

How Does Authentication Work In Java

Introduction to Authentication Java

Authentication java is a term of the security to identity confirmation of web applications. It is a function to confirm user identification of the websites & web applications using a programming language. It confirms the users’ use and permits them to access the website, application, and software-related products using Java technology. It is a security method to identify the authorized user and give permission to use the application using the security terms of the Java language.

Web development, programming languages, Software testing & others

It is a client and server-side function to use unique content and confirm with a security password and user identity. It is used the user id and password on the client side and accesses the server-side data with true identification using a Java programming language. It is a documentation process to keep a secure web application and use only accessible team members.

Syntax

In this syntax, the application uses a username and password for authentication.

public class AppSecurityConfig extends AppSecurityConfigurerAdapter { @Override protected void configure(AuthenticationManagerBuilder authentic) throws Exception { UserBuilder userid = User.withDefaultPasswordEncoder(); authentic.inMemoryAuthentication() .withUser(usersid.username("merry").password("[email protected]").roles("student")) } @Override http.authorizeRequests() .antMatchers("/").hasRole("student") .and() .formLogin() .loginPage("/useLoginPage") .loginProcessingUrl("/authenticatationUser") .permitAll() .and() .logout().permitAll(); } } How does Authentication work in Java?

Use web application with security and login form. This form redirects to the JSP page.

<form:form action="${pageContext.request.contextPath}/authenticateUser"

Use a web application for authentication of the login form. This form redirects to the JSP page.

Use Java authentication syntax using java spring frameworks. Java uses Spring security to authenticate the authority.

public class AppSecurityConfig extends AppSecurityConfigurerAdapter { @Override protected void configure(AuthenticationManagerBuilder authentic) throws Exception { UserBuilder userid = User.withDefaultPasswordEncoder(); authentic.inMemoryAuthentication() .withUser (usersid.username ("merry") .password ("[email protected]") .roles ("student")) } @Override http.authorizeRequests() .antMatchers("/") .hasRole("student") .and() .formLogin() .loginPage("/useLoginPage") .loginProcessingUrl("/authenticatationUser") .permitAll() .and() .logout().permitAll(); } } Examples of Authentication Java

How Does Listview Work In Javafx?

Introduction to JavaFX ListView

JavaFX ListView is a class used to choose one or more choices from the list. ListViewclass is available within scene.control.ListView package. ListView allows us to add as many elements as we want. The user may additionally add elements to ListView either horizontally or vertically. ListView can be allowed to add images to the list values. ListView is used to select single or multiple values at a time.

Web development, programming languages, Software testing & others

Real-Time Example: While installing any application into the Windows PC, many features are there to select. But we didn’t choose all the features because we are choosing the feature because we are allowing additional software to install in the background. So, we choose the required features from the list. In this case, we can use the ListView Multi-select option.

How does ListView work in JavaFX?

Accessing JavaFX features user-defined class must extend the Application class.

Step 1: In JavaFX, creating is the first step. ListView can instantiate by using the new keyword.

Syntax:

ListFView listViewRef=new ListView();

Step 2: Adding elements or items to thelistViewRef is the second step. Items can be added in 2 ways:

1. By using add() Method

Syntax:

listViewRef.getItems().add(“item-name”);

getItems(): Used for showing the list item to the user.

2. By using ObservableList Class

Syntax:

FXCollections.observableArrayList(): Takes the all possible Typed list of items.

Note: A recommended way to add the elements to the ListView is ObservableList. Because, This ObservableList, by default observed with the ListView, allows any changes that occur inside the Observable list and updates the ListView automatically.

Step 3: The third step is to create a horizontal or vertical box to add the items.

Syntax:

HBox hBox=new HBox(); VBox vBox=new VBox();//Gives vertical box

Step 4: Creating a scene means screen to display output is the fourth step.

Syntax:

Scene screen = new Scene(hBox or vBox, length, width);

Step 5: Adding a Scene reference screen to the Stage object reference is the fifth step. We are adding an output screen to Stage. We will get this stage object reference from the start predefined JavaFX method.

Syntax:

stage.setScene(screen);

Syntax:

stage.show(); Examples of JavaFX ListView

Following are the different examples of JavaFX Listview.

Example #1 – Adding Items Horizontally to the ListView

Code:

import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.ListView; import javafx.scene.layout.HBox; import javafx.stage.Stage; public class AddingItemsListView extends Application { @Override public void start(Stage displayScreen) throws Exception { /* create list object */ /* adding items to the list view */ listViewReference.getItems().add("First Item"); listViewReference.getItems().add("Second Item"); listViewReference.getItems().add("Third Item"); listViewReference.getItems().add("Fourth Item"); listViewReference.getItems().add("Fifth Item"); /*making list view horizontal*/ listViewReference.setOrientation(Orientation.HORIZONTAL); /* creating horizontal box to add item objects */ HBox hbox = new HBox(listViewReference); /* creating scene */ Scene scene = new Scene(hbox, 400, 200); /* adding scene to stage */ displayScreen.setScene(scene); /* display scene for showing output */ displayScreen.show(); } public static void main(String[] args) { /*launch method calls internally start() method*/ Application.launch(args); } }

Output:

Explanation: As you can see from the output, items are added horizontally. You can scroll the scroll bar to see more items like in the output.

Example #2 – Adding Items Vertically to the ListView

Code:

import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.ListView; import javafx.scene.layout.VBox; import javafx.stage.Stage; public class AddingItemsListView extends Application { @Override public void start(Stage displayScreen) throws Exception { /* create list object */ /* adding items to the list view */ listViewReference.getItems().add("First Item"); listViewReference.getItems().add("Second Item"); listViewReference.getItems().add("Third Item"); listViewReference.getItems().add("Fourth Item"); listViewReference.getItems().add("Fifth Item"); /* creating vertical box to add item objects */ VBox vBox = new VBox(listViewReference); /* creating scene */ Scene scene = new Scene(vBox, 220, 270); /* adding scene to stage */ displayScreen.setScene(scene); /* display scene for showing output */ displayScreen.show(); } public static void main(String[] args) { /*launch method calls internally start() method*/ Application.launch(args); } }

Output:

Explanation: As you can see from the output, items are added vertically. By default alignment of the list, the view is vertical.

Example #3 – Select Multiple Items from the ListView

Code:

import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.ListView; import javafx.scene.control.SelectionMode; import javafx.scene.layout.VBox; import javafx.stage.Stage; public class SelectingMultipleItemsListView extends Application { @Override public void start(Stage displayScreen) throws Exception { /* create list object */ /* adding items to the list view */ listViewReference.getItems().add("First Item"); listViewReference.getItems().add("Second Item"); listViewReference.getItems().add("Third Item"); listViewReference.getItems().add("Fourth Item"); listViewReference.getItems().add("Fifth Item"); /*Make listview to select multiple values*/ listViewReference.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE); /* creating vertical box to add item objects */ VBox vBox = new VBox(listViewReference); /* creating scene */ Scene scene = new Scene(vBox, 220, 270); /* adding scene to stage */ displayScreen.setScene(scene); /* display scene for showing output */ displayScreen.show(); } public static void main(String[] args) { /*launch method calls internally start() method*/ Application.launch(args); } }

Output:

Example #4 – Adding Items to the ListView

Code:

import javafx.application.Application; import javafx.collections.FXCollections; import javafx.collections.ObservableList; import javafx.scene.Scene; import javafx.scene.control.ListCell; import javafx.scene.control.ListView; import javafx.scene.image.Image; import javafx.scene.image.ImageView; import javafx.scene.layout.VBox; import javafx.stage.Stage; public class AddingImagesToItemsListView extends Application { /*loading images with their paths*/ private final Image cabinetImage  = new Image("Cab.png"); private final Image docIconImage  = new Image("documenticon.png"); private final Image homeCabImage  = new Image("HomCab.png"); private final Image searchIconImage = new Image("searchicon.png"); /*image array to load all images at a time*/ private Image[] imagesArray = {cabinetImage, docIconImage, homeCabImage, searchIconImage}; @Override public void start(Stage displayScreen) throws Exception { /* create list object */ /* adding items to the list view */ "Fourth Image"); listViewReference.setItems(elements); /*setting each image to corresponding array index*/ /*view the image class to display the image*/ private ImageView displayImage = new ImageView(); @Override public void updateItem(String name, boolean empty) { super.updateItem(name, empty); if (empty) { setText(null); setGraphic(null); } else { if (name.equals("Fist Image")) displayImage.setImage(imagesArray[0]); /*setting array image to First Image*/ else if (name.equals("Second Image")) displayImage.setImage(imagesArray[1]);/*setting array image to Second Image*/ else if (name.equals("Third Image")) displayImage.setImage(imagesArray[2]);/*setting array image to Third Image*/ else if (name.equals("Fourth Image")) displayImage.setImage(imagesArray[3]);/*setting array image to Fourth Image*/ setText(name); setGraphic(displayImage); } } }); /* creating vertical box to add item objects */ VBox vBox = new VBox(listViewReference); /* creating scene */ Scene scene = new Scene(vBox, 220, 270); /* adding scene to stage */ displayScreen.setScene(scene); /* display scene for showing output */ displayScreen.show(); } public static void main(String[] args) { /* launch method calls internally start() method */ Application.launch(args); } }

Output:

Explanation:

First, paste all the images to the eclipse src folder, then give their names in the Image class.

Now you can see the output in the above image.
