Animate Color Changes with Variables

Image
Animating Color Changes with CSS Custom Properties (Variables) Modern web interfaces demand dynamism and interactivity. Smooth color transitions on buttons, backgrounds, or text can significantly enhance user experience, providing visual feedback and a sense of polish. While CSS has long supported the transition property for animating changes, combining it with CSS Custom Properties (commonly called CSS Variables) unlocks a new level of power and maintainability. This tutorial will guide you through using CSS Variables to create centralized, easily adjustable color schemes and animate between them seamlessly. We will build a simple card component where multiple properties (background, text color, border) change simultaneously with a single hover trigger, all powered by CSS Variables and smooth transitions. Why Animate Colors with CSS Variables? CSS Variables, defined with -- syntax, offer significant advantages for animation and design systems: Centralized Control: D...

Dynamic Function Dispatch with Dictionaries

Image
Learn how to replace long if-else chains in Python with clean and efficient dynamic function dispatch using dictionaries. Debian 12 GNOME. Dynamic Function Dispatch in Python with Dictionaries In this tutorial, we will explore how to replace repetitive if-elif-else chains with a more scalable and elegant approach: dynamic function dispatch using dictionaries. This technique allows us to map string or key inputs directly to functions, simplifying the control flow of our programs and improving readability. What is Dynamic Dispatch? Dynamic dispatch refers to deciding which function to call at runtime rather than hardcoding every condition. In Python, this can be achieved easily using dictionaries where keys represent actions and values point to callable objects like functions or lambdas. Why Use Dictionaries for Dispatch? Dictionaries provide constant-time lookup and make it easier to extend your program. Instead of modifying a lon...

Socket Programming in C TCP Client and Server

Image
Learn socket programming in C by building a simple TCP client and server on Debian 12. This tutorial covers creating sockets, connecting, sending, and receiving data with clear code examples using Vim. Socket Programming in C: TCP Client and Server Socket programming lets your C programs communicate over networks. This tutorial shows how to create a TCP client and server using sockets on Debian 12. TCP Server The server creates a socket, binds to a port, listens for connections, and accepts one client. It then receives a message and replies back. Server Code Example // tcp_server.c #include #include #include #include #include #define PORT 8080 #define BUFFER_SIZE 1024 int main() int server_fd, new_socket; struct sockaddr_in address; int addrlen = sizeof(address); char buffer[BUFFER_SIZE] = 0; char *hello = \\"Hello from server\\"; if ((server_fd = socket(AF_INET, SOCK_STREAM, 0)) == 0) perror(\\"socket failed\\...

Pointers and Arrays in C

Image
Learn how pointers and arrays work together in C on Debian 12 using Vim. Understand their relationship, how to traverse arrays using pointers, and practical examples. Pointers and Arrays in C In C, pointers and arrays are closely related. The name of an array acts like a constant pointer to its first element. This relationship allows pointers to be used for traversing and manipulating arrays efficiently. Array Name as Pointer When you use an array name in an expression, it is converted to the address of its first element. Example: int numbers[3] = 10, 20, 30; printf(\\"%p\\", numbers); // address of first element printf(\\"%p\\", &numbers[0]); // same address Accessing Array Elements with Pointers Pointers can be incremented to move through array elements without using square brackets. int *ptr = numbers; printf(\\"%d\\", *ptr); // first element ptr++; printf(\\"%d\\", *ptr); // second element Complete Example The following ...
