This tutorial will help us in checking whether a variable is defined or not. In Haskell, a variable is considered defined if it has a value assigned to it. The value can be of any type, including a special type called Maybe that is used to represent values that may or may not be present. Algorithm Step 1 − The Data.Maybe module is imported. Step 2 − The checkDefined function is defined as, checkDefined x = isJust x. It takes a Maybe value and returns a Bool indicating whether the value is Just (i.e. defined) or Nothing (i.e. not ...

In Haskell, this program will help us in checking the current date against a specified birthday and prints a "Happy Birthday" message if it is a match otherwise, it will print “Not your birthday yet”. Haskell provides function to fetch the current date and also to specify a date. This program can be implemented by using various approaches including the use of toGregorian function, fromGregorian function or by using utctDay getCurrentTime. This program will only check the birthday once, when the program runs. If we want the program to check the birthday periodically or at a specific time, we ... Read More
A content management system (CMS) is used to generate and update digital files. CMS allows for web-based posting, content management, version control, and many other features. There are various CMSs, two of which are Joomla and WordPress. Joomla is more adaptable, versatile, and durable than WordPress. Two open-source content management systems are Joomla and WordPress. The main differentiation between Joomla and WordPress is that Joomla is better suited for e-commerce, social media, and moderate to large businesses. In contrast, WordPress is best suited for small to medium-sized companies, blogs, and smaller e-commerce sites. WordPress and Joomla are both content administration ... Read More
Intranets and VPNs are two devices that are widely used in business. It is crucial to clarify that an intranet is merely a term that refers to an internal network that simulates the Internet. Still, VPN, which means Virtual Private Network, is one method used to remotely connect to a system as if you were linked locally. Using applied research makes it easy for administrators to provide different levels of accessibility in a manner that most people are already familiar with. On the other hand, VPN was created to address the need for low-cost, secure connections between distant workplaces. Before ... Read More
Nowadays, there is no need to spend a lot of money just to convert your films and store them on your smartphone or even other devices. There's really software available that performs the job rather effectively and is free. Handbrake and Freemake video converters are two examples of this. The main difference between Handbrake and Freemake is indeed the platforms aboutwhich they operate. Freemake is exclusively available for Windows users. Handbrake, on the other hand, is cross-platform and is accessible to Windows, Mac, and Linux users. Handbrake's lone advantage in this comparison is that it is multi-platform. Starting with the ...

Users can use microblogging tools to share brief pieces of content such as textual captions, images, or videos. Examples of micro-blogging websites include Facebook, Twitter, and Instagram. ...

In Haskell, an enumeration (or "enum") is a type that has a finite set of values. The values are called constructors, and are usually defined using the data keyword. Here's an example of an enumeration type that represents the four seasons − data Season = Spring | Summer | Fall | Winter Enumerations are used to represent things like states, modes, or options that have a fixed set of possible values. Method 1: Iterate over enumeration type This method is used to directly iterate over the enumeration type in Haskell. Here, we define the list of all the enumeration ... Read More
Big Data and Hadoop are the two most frequently used phrases today. Both are interconnected in such a way that Big Data cannot be handled without the assistance of Hadoop. Big Data is a term used to describe a collection of large and complex data sets that are difficult to store and process using conventional database management technologies or traditional data processing applications. Collecting, selecting, storing, searching, exchanging, transferring, evaluating, and visualizing the data is part of the challenge. We are surrounded by a huge amount of information in today's digital environment. The fast expansion of the Internet and the ... Read More
