Java Records vs. Lombok

Aggregated on: 2022-04-01 04:35:26

Java for a lot of time has been accused and mocked for its verbosity. Even the most passionate Java developers have to admit that it felt ridiculous to declare a bean class with two attributes. If you follow the right recommendations, you end up adding not only getters and setters, but also the implementations of toString hashcode and equals methods. The final result is a chunk of boilerplate that invites you to start learning another language. Java import java.util.Objects; public class Car { private String brand; private String model; private int year; public String getBrand() { return brand; } public void setBrand(String brand) { this.brand = brand; } public String getModel() { return model; } public void setModel(String model) { this.model = model; } public int getYear() { return year; } public void setYear(int year) { this.year = year; } @Override public String toString() { return "Car{" + "brand='" + brand + '\'' + ", model='" + model + '\'' + ", year=" + year + '}'; } @Override public boolean equals(Object o) { if (this == o) return true; if (o == null || getClass() != o.getClass()) return false; Car car = (Car) o; return year == car.year && Objects.equals(brand, car.brand) && Objects.equals(model, car.model); } @Override public int hashCode() { return Objects.hash(brand, model, year); } }

How to Debug Selenium-Based Test Scripts

Aggregated on: 2022-04-01 04:05:26

Writing and maintaining the test automation code is not always a piece of cake. As a matter of fact, we frequently face many scenarios where automated test cases don’t work as expected and might lead to false positive or false negative results, in such cases, debugging is the only way out. Debugging is the primary skill set that an automation tester must adopt. It increases the morale and confidence in automation testers to provide a better code solution to fix the problem permanently. Debugging issues in the test automation framework become more complicated when the test automation framework has a huge number of test cases. With the expansion of features in the application, the number of test cases gradually increases. In such a scenario, fixing complex issues of hybrid frameworks might require enhanced techniques of debugging. In this article, we will deep dive into such essential debugging techniques that will not only fix script issues easily but also save a good amount of debugging time.

MongoDB: User Cases, Pros, and Cons.

Aggregated on: 2022-03-31 21:05:26

MongoDB is a document-based database management system commonly used for high-volume data storage. It is an easy tool to manage data and was developed to substitute the MySQL structure, as the growth of data required new tools for its management. MySQL became outdated for its lack of flexibility for reformatting data structures. The problem lies within a table-based design, as it makes the set of multivariate search queries finite. Enterprises rely on a combination of structured and unstructured data for business decisions, giving MongoDB rapid growth. MySQL is a table-based system or open-source relational database, while MongoDB is also called an object-based system. A table-based design is the data query structure for search, where all data is related to another data point or set. Data in MongoDB, on the contrary, is non-relational. Instead of using tables and rows, MongoDB makes collections and documents. The documents are formed from key-value pairs – the core units of the system. Unlike rows, documents can store information that is complex in structure. Sets of documents and functions are united in the collections, which can be equivalent to relational database tables. MongoDB allows you to represent store arrays, hierarchical relationships, and other more complex structures.

The Principles of Test Automation

Aggregated on: 2022-03-31 04:05:25

The word “test” originally referred to “a small vessel used in assaying precious metals.” This meant that testing was a method of ascertaining the quality of gold or silver. It was also used in the process of refining valuable alloys, such as tin. Later, the term was adopted in other fields, and these days it’s common to find it in contexts such as education, medicine, or software development. Its essence, however, has not changed: testing is used to refine end value.

Making the Case for Observability to Your Boss

Aggregated on: 2022-03-31 04:05:25

One of the things the other developer relations advocates here at New Relic and I often hear from customers is, "Even though I understand why observability is important, I'm having a dickens* of a time getting leadership to buy in (literally)." Let me begin by pointing out how important it is for us — IT practitioners — to be willing and able to speak to management and leaders of the business about the work we do, and to do so in a way that is understandable and meaningful to the audience. I'm not implying you have to explain observability in a patronizing "explain it like they're five" kind of way. I mean you need to explain the WHY of observability in the context of what the audience feels is important.

How AI Is Used in Static Biometric Verification

Aggregated on: 2022-03-31 03:35:25

Static biometric verification is a commonly used AI feature that captures faces in real time and can determine whether a face belongs to a real person or not, without prompting the user to move their head or face. In this way, the service helps deliver a convenient user experience that wins positive feedback. Technical Principles Static biometric verification requires an RGB camera and is able to differentiate between a real person's face and a spoof attack (such as an image or screenshot of a face and a face mask), through details (such as the moiré pattern or reflection on a paper photo) in the image captured by the camera. The service supports data from a wide array of scenarios, including different lighting conditions, face accessories, genders, hairstyles, and mask materials. The service analyzes a face's surroundings to detect suspicious environments.

How the chmod Command Works on Linux

Aggregated on: 2022-03-31 02:20:25

2 Billion MySQL Records

Aggregated on: 2022-03-30 18:05:25

Yesterday Gary Gray, a friend of mine sent me the following screenshot. He's got a database table with 2 billion records he intends to use Magic on, and he wanted to show it to me, thinking I'd probably be like, "That's cool." Gary works for Dialtone in South Africa, and is used to handling a "monster amount of data". For the record, neither Gary nor I would want to encourage anyone to handle 2 billion records in MySQL, but as you can obviously, see it is possible. This of course is a legacy system. If it was started today, Gary would obviously use ScyllaDB, Cassandra, or something similar. Simply counting the records in the table above requires 5 minutes of execution in MySQL workbench. Obviously, such sizes are not for those faint at heart. Such a database also implies a lot of inserts. This makes it impossible to add indexes, resulting in every select query you do towards it having some sort of where clause in it that implies a full table scan. However, it is possible.

Regardless, the fact remains that it is both extremely popular and used in almost every industry we can think of. People working with the server generally use it to support software solutions on the web, but its use cases vary from industry to industry thanks to its high availability, performance including data storage and security.

Functional Interface Explained in Detail Introduced From Java 8

Aggregated on: 2022-03-29 03:50:24

Originally published August 2020 Functional interfaces are introduced as part of Java 8. It is implemented using the annotation called @FunctionalInterface. It ensures that the interface should have only one abstract method. The usage of the abstract keyword is optional as the method defined inside the interface is by default abstract. It is important to note that a functional interface can have multiple default methods (it can be said concrete methods which are default), but only one abstract method. The default method has been introduced in interface so that a new method can be appended in the class without affecting the implementing class of the existing interfaces. Prior to Java 8, the implementing class of an interface had to implement all the abstract methods defined in the interface.

Old Habits Die Hard, But Getting New Ones is Essential. Tips on Getting the Most Out of TypeScript

Aggregated on: 2022-03-28 22:50:24

In web development, no one is surprised when a new framework or library enters the stage. Implementing complex functionalities and creating UI elements from scratch only using the powers of a specific programming language is not always the most optimal way. Instead, developers either rely on the existing frameworks or create their own for internal use. In the case of programming languages, the situation is a little more complicated. A fairly large number of coders are unhappy with the limitations of the programming language that they use every day. Therefore, from time to time, we can hear about the new programming language release. The question is, will the development community adopt it as a replacement for well-established technologies? As an example, we can take a look at Dart. It was initially released in 2011 but remained quite unpopular until the Flutter framework was launched in 2017.

Javascript Map and How It Is Different From Foreach

The map method is one of the most used functions in Javascript. It is used to take arrays, and return a new array which can be changed with an attached function. When you start developing in Javascript, you'll see map everywhere. Let's look at how it works. How Map Works in Javascript map()is a method of arrays. That means you can only use map on something which is typed as an array. For example, [ 1, 2, 3 ].map() will work, but 14.map() will not.
