Introduction Are you looking to speed up your web development process? A UI library might be just what you need! This article explores the top 5 modern UI libraries that can help you build stunning web applications quickly and efficiently. A UI library is a collection of pre-designed and pre-built user interface elements (such as Buttons, Menus, Lists, Dropdowns, etc.) used to build user interfaces for a web application in a unified design style. In a conventional web development workflow, you usually need a UI/UX designer to design the user interfaces before developing a web application. Although this is a…

In this post, we will explore how to create a complete API using the Effect ecosystem. Although the Effect documentation is excellent, there are not many examples of full applications. If you have never heard of Effect, I suggest you take a look at the website: https://effect.website/ Effect is not just another framework but instead acts as the missing standard library for TypeScript. Because of this, I believe Effect is truly the future for TypeScript, especially when considering the challenges associated with writing production-ready applications in "plain" TypeScript. To understand more about these challenges and how Effect addresses them, watch…

Hello everyone! When you're working with Bash scripts, it's often useful to know the directory where the script itself resides. This can be essential for referencing relative paths, ensuring the script works correctly regardless of where it is executed from. Let’s dive into how you can achieve this. Method 1: Using dirname and $0 The simplest way to get the directory of the script is to use the dirname command in combination with $0. Here's a step-by-step explanation: $0: This special variable contains the path used to invoke the script. It might be a relative path, an absolute path, or…

Text I/O vs. Binary I/O

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, java, learning, programming, software

Binary I/O does not involve encoding or decoding and thus is more efficient than text I/O. Computers do not differentiate between binary files and text files. All files are stored in binary format, and thus all files are essentially binary files. Text I/O is built upon binary I/O to provide a level of abstraction for character encoding and decoding, as shown in Figure below (a). Encoding and decoding are automatically performed for text I/O. The JVM converts Unicode to a file-specific encoding when writing a character, and it converts a file-specific encoding to Unicode when reading a character. For example,…

Problem description & analysis: Below is an irregularly categorized detail table. Column A and column B are categories and both have duplicate values. Column C contains detailed data consisting of strings separated by "comma+space", and there are duplicates among the string values. Task: Split detail data in each category, group them by category, get unique values of each group, and concatenate them using "comma+space". Solution: Use SPL XLL to enter the following formula: =spl("=E@b(?.group(~1,~2;~.conj(~3.split@ct()).id().concat("","")))",A2:C12) Enter fullscreen mode Exit fullscreen mode As shown in the picture below: Explanation: group()function groups rows and handles data in each group; ~1 represents the first…

What is Associative Arrays in Computer Science

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, programming, software, tutorial, webdev

In computer science, an associative array, map, symbol table, or dictionary is an abstract data type that stores a collection of (key, value) pairs, such that each possible key appears at most once in the collection. In mathematical terms, an associative array is a function with a finite domain. It supports 'lookup', 'remove', and 'insert' operations. The Dictionary Problem The dictionary problem is the classic problem of designing efficient data structures that implement associative arrays. The two major solutions to the dictionary problem are hash tables and search trees. It is sometimes also possible to solve the problem using directly…
