OpenCV (Open Source Computer Vision Library) is a popular open-source toolkit for computer vision, image processing, and machine learning. It allows you to analyze visual input and automate tasks that involve interpreting images or videos. Key capabilities of OpenCV: Basic example: Load and display image pythonКопироватьРедактироватьimport cv2 image = cv2.imread(‘photo.jpg’) cv2.imshow(‘Photo’, image) cv2.waitKey(0) cv2.destroyAllWindows() Common…
Blockchain programming involves creating decentralized applications (dApps) and smart contracts that run on peer-to-peer networks like Ethereum. Unlike traditional apps, dApps run on blockchain nodes and execute code transparently. Core concepts: Popular platforms: Simple Solidity contract: solidityКопироватьРедактироватьpragma solidity ^0.8.0; contract Counter { uint public count = 0; function increment() public { count += 1; }…
WebAssembly (Wasm) is a low-level binary instruction format that allows high-performance applications to run in browsers—at near-native speed. It opens the door for languages like C, C++, and Rust to compile and run on the web. Why WebAssembly matters: Key features: Use cases: Example workflow: WebAssembly is still evolving but has strong backing from all…
GraphQL and REST are two popular paradigms for building APIs, each with its own strengths and use cases. REST (Representational State Transfer): Pros: Cons: GraphQL: Pros: Cons: Use GraphQL when front-end flexibility is crucial or data relationships are complex. Use REST when simplicity, scalability, and widespread tooling are more important.
Mastering data structures and algorithms (DSA) is key to writing efficient code and solving complex problems. Python’s simplicity makes it a great language for learning and implementing core DSA concepts. Essential data structures in Python: Advanced structures: Key algorithms: Example: Binary Search pythonКопироватьРедактироватьdef binary_search(arr, target): left, right = 0, len(arr)-1 while left <= right: mid…
