Introduction Security has always been a great threat to mankind. In IT the security of credentials is a tedious task. Here, we are going to discuss various methods to add the credentials to the docker container. Also, the most useful and secure methods are mentioned. Methods Adding credentials can be done in a lot of different ways. Some of the types are mentioned below. Each method has its place in the industry. Some are just rejected by the developers due to security issues and some works very well in the case of credential security. Using the Build ... Read More
IPSec is a suite of protocols that provides security services during communications between networks. It supports network-level peer authentication, data origin authentication, data integrity, data encryption and decryption. It is often used to create a VPN.SSL is a networking protocol that provides a secure connection between a client and a server over the internet. It works at the transport layer. It is often used to secure the communication between a web browser and a web server.Read through this article to find out more about IPSec and SSL and how they are different from each other.What is IP Security (IPSec)?IPSec is ...

CRT and LCD are both display devices. CRT is an old technology whereas LCD is modern one. One major difference between CRT and LCD is in the technology used for image formation. The CRT display produces an image by using an electron beam, while LCD display produces an image on the screen using liquid crystal display. What is a CRT? CRT stands for Cathode Ray Tube. CRT displays produce an image on the screen by using a sharp beam of electrons that is highly focused to hit a phosphor screen present in front of the tube. The important components of ... Read More
JavaScript is a lightweight and interpreted language, therefore, inside the context of a web browser, you don't even need to buy a compiler. You can start with a simple text editor such as Notepad. To make our life simpler, various vendors have come up with very nice JavaScript editing tools. Some of them are listed here − Microsoft FrontPage − Microsoft has developed a popular HTML editor called FrontPage. FrontPage also provides web developers with a number of JavaScript tools to assist in the creation of interactive websites. Macromedia Dreamweaver MX − Macromedia Dreamweaver MX is a very popular ...

In JavaScript, the NaN property is a special value that represents "Not a Number". It is a property of the Number object and can be accessed using Number.NaN. The NaN property is usually produced as a result of an operation that cannot produce a meaningful result. For example, dividing 0 by 0 or trying to parse an invalid number will both produce NaN. Here are a few examples of operations that will produce NaN − Math.sqrt(-1); // NaN 0/0; // NaN parseInt("foo"); // NaN It ... Read More
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to increment all negative numbers by 1 and decrement all positive numbers by 1. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose the original array is {12, 21, -31, -14, 56, 16, 17, -18, 9} After updating the array element are: -30 -17 -13 8 11 15 16 20 55 (sorted) Instance-2 Suppose the original array is {19, ...

To catch all JavaScript errors, we can use the window.onerror() method which acts like a global try-catch statement. The onerror event handler was the first feature to facilitate error handling in JavaScript. The error event is fired on the window object whenever an exception occurs on the page. The onerror event handler provides three pieces of information to identify the exact nature of the error − Error message − The same message that the browser would display for the given error URL − The file in which the error occurred Line number− The line number in the given ...

In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to delete or eliminate the odd numbers present in the array and print the even array. Note − The array must be an integer array. A number is said to be an odd number if the array is not divisible by 2. In this article, you will see how to remove odd numbers from an array by using Java programming language. Let’s explore. To Show You Some Instances Instance-1 Suppose the original array is ... Read More

Organizations have realized that the field of project management provides tried-and-true approaches and instruments to help them complete their tasks and reach their goals more effectively and successfully. Because it covers such a wide range of topics, project management really uses and incorporates different management philosophies. The theory of limitations is one of these concepts. The principle of constraints can be useful in regulating almost any project. The Theory of Constraints According to the notion of limitations, certain restrictions prevent any management or production system from accomplishing more of its objectives. The theory of constraints employs five focusing steps ... Read More
