speak numbers follow one movie review through cleaning tokenizing stopwords and stemming to see how text becomes something a model can read 10 min ️ nlp bag of words tf idf turn three tiny movie reviews into numbers by hand count words compare reviews catch common words cheating and fix it with tf idf 10 min nlp word embeddings words as points in space turn words into short lists of numbers where similar words sit close together then do king minus man plus woman by hand 11 min ️ nlp language models guessing the next word count word pairs in four tiny sentences turn them into next word guesses and see why counting breaks and how a neural network fixes it 12 min nlp seq2seq the bottleneck problem translate a sentence with two rnns one that reads and one that writes then watch a long sentence get crushed into one small note and see the idea that fixed it 11 min dsa time and space complexity the scale lens dungeon 0 before you fight any boss learn to read the o n runes a complete interview ready guide to time and space complexity how to analyze any code say the answer out loud and then make it faster 20 min ️ dsa rotate image the mural turn dungeon 18 boss 1 a museum s square mosaic mural must make a quarter turn clockwise but the tiles are mortared to a frame that cannot move and no second frame exists all you can do is swap tiles in place mirror the mural across its diagonal then flip each row and two reflections quietly add up to one rotation 8 min dsa spiral matrix the spiral plow dungeon 18 boss 2 a farmer plows a rectangular field in a spiral never crossing a furrow he s already cut and you have to write down the order the soil turns four boundary fences that shrink inward do the whole job but skip one mid loop check and a single row field gets plowed twice 9 min show all articles latest guides click any card to explore an interactive guide ️ programming elo rating system learn how the elo rating system turns wins and losses into skill ratings expected scores k factors zero sum updates and why beating a stronger player pays more by obydul programming bloom filters understand how bloom filters use hash functions and bit arrays to answer membership queries with zero false negatives perfect for space constrained systems by obydul ️ system design client server architecture client server architecture is the foundational model of modern networked applications clients send requests servers process and respond understanding this model is the first step to mastering distributed systems apis and scalable web applications by obydul system design proxy servers a comprehensive guide to forward proxy and reverse proxy their differences use cases and how they protect clients and servers by obydul ️ system design microservices architecture breaking down monolithic applications into small independent loosely coupled services by obydul system design monolithic architecture a single unit software architecture where all components are tightly coupled by obydul ️ system design serverless architecture serverless architecture allows building and running applications without managing infrastructure by obydul programming big o notation
