Embracing margin-inline-start for Better RTL Support in Web Design

  • Embracing margin-inline-start and other logical CSS properties improves flexibility and consistency in designing for left-to-right (LTR) and right-to-left (RTL) languages.
  • Logical properties, such as margin-inline-start and margin-inline-end, are direction-agnostic and adapt based on the writing mode of the document or element.
  • Benefits of using margin-inline-start include seamless RTL support, cleaner code without direction-specific styles, and future-proof scalability.
  • Logical properties like margin-inline-start are well-supported in modern browsers and ensure more inclusive and adaptable designs for a global audience.

Functional Programming with fp-ts in Node.js

  • Functional programming (FP) has gained popularity for its composability, testability, and robustness.
  • This article explores fp-ts concepts like Option, Either, Task, Reader, and ReaderTaskEither.
  • We’ll build a basic CRUD app using fp-ts, pg (PostgreSQL client), and Express.js to see how these abstractions shine in real-world applications.
  • Setup TypeScript, Project Structure, Database Setup, Defining Models and Validation, Custom Error Handling, Service Layer, CRUD Operations and Express API have been implemented to build the CRUD app.
  • Containerization using Docker and Docker Compose and Writing tests using Jest have also been demonstrated.
  • Using functional programming patterns makes your code more predictable and reliable, especially when handling asynchronous workflows.

Reverse a string in JavaScript without using reverse()

  • The JavaScript program reverses a string without using the reverse() method.
  • It defines a function named reverseString that takes a string as input.
  • The function iterates through the string from the last character to the first and appends each character to a reversed string.
  • Finally, the reversed string is returned as the result.

The Counterintuitive Truth About the Single Responsibility Principle

  • The Single Responsibility Principle (SRP) is often misunderstood as meaning that every part of a program should do only one thing.
  • However, the SRP is about a larger concept than just individual functions.
  • It can be compared to organizing a room, where each drawer holds one type of clothing, similar to functions.
  • The SRP states that the entire room should be the responsibility of one person and should not contain items belonging to others.

Introduction to Dynamic Programming with example

  • Dynamic programming is a method of solving problems with overlapping sub-problems and optimal substructures that can be optimised with the help of storing previously calculated solutions.
  • There are two approaches: top-down approach (memoization) and bottom-up approach (tabular method).
  • Dynamic programming can significantly reduce time complexity.
  • Memoization approach is a top-down approach where previously calculated solutions are stored in an array to eliminate redundancy.
  • The array is initialised with -1 and the values are filled for future use as required.
  • Tabular method is a bottom-up approach for dynamic programming where the solutions are iteratively calculated and stored in an array.
  • The array is filled from lower index to higher index in this case.
  • Memoization and tabular method have been explained using examples of generating Fibonacci numbers.
  • C++ programs for finding Fibonacci numbers using memoization and tabular method have been provided.
  • Dynamic programming is a powerful technique for optimisation of overlapping sub-problems.

Introduction to Recursion with stack frame and recursion tree

  • The article explains recursion function and its implementation using a simple program in C language.
  • The article discusses the changes in the stack frame when using a recursion function and helps in understanding recursion tree with an example of finding the nth Fibonacci number.
  • It explains how local c variables are stored in the stack when a function is called with its activation record and the changes that occur when recursive calls are made.
  • The program uses function fun to demonstrate how the stack frame gets affected when a recursion function is used.
  • The recursion tree is a visual representation of recursive calls that helps in understanding the complexity of a function with multiple recursive calls.
  • The article also describes the pseudo code to find the nth Fibonacci number and its implementation with a recursion tree.
  • The article concludes with the importance of recursion in dynamic programming and backtracking and its role in getting the desired results.
  • Understanding recursion is important for any programmer and helps in writing efficient code with minimal errors.
  • Recursion can be used to solve complex problems easily by dividing the problem into simple sub-problems.
  • Recursion helps in developing code that is reusable and helps in reducing the complexity of code by breaking it into smaller functions.

Graph data structure tutorial 10. Hamiltonian Graph

  • A graph that contains Hamiltonian circuit is called as Hamiltonian graph.
  • A path that passes through every vertex exactly once is called as Hamiltonian circuit.
  • If a graph has a Hamiltonian path, it means it visits all the vertices, but cannot return to the initial vertex.
  • Finding a Hamiltonian circuit or path is a NP complete problem.

Scala Factory Pattern - Every Engineer’s Favorite Way to Store Objects

  • Scala Factory Pattern is widely used by engineers to store objects for ease of its creation.
  • The blog covers various topics like Types of Factory Patterns, Components of the Factory Pattern, Scala-Specific considerations, and Advanced topics.
  • Scala Factory Pattern comprises of three types of patterns: Simple Factory, Factory Method, and Abstract Factory.
  • FastFoodFactory represents a fast food joint that creates products such as a Burger or Pizza based on the client's order.
  • In Factory Method, the chefs are responsible for preparing the customers' dish based on specifications like spicy or sweaty dishes.
  • Abstract Factory is for clients seeking a cohesive set of products that pair well together. Each factory is prepared by a different chef.
  • Factory Pattern's Components are the product interface, concrete products, factory interface, concrete factory, and the client.
  • Scala enthusiasts can use Singleton objects to ensure that no matter how many times they request products, they get the same factory.
  • Scala's Trait is used to ensure that factory interfaces are flexible and mixable, making it simple to expand them later.
  • Scala's pattern matching assists in serving the right product quickly and efficiently and avoiding mixed Factory and Product roles.
