A/B TESTING AT SCALE: HOW WE ENGINEERED A SOLUTION FOR MILLIONS OF USERS WITH AWS

To conduct large-scale A/B tests without sacrificing user experience, Unacademy engineered a solution using AWS serverless tech. Instead of determining which test variant to show after the page loads (causing a distracting flicker), its team selected a test variant before the webpage even reached the user's browser. This was done by running code at the network edge to intercept requests, determine the variant, and fetch the appropriate content from the CDN.

THE TWO-TREE PROBLEM WITH STYLING ON THE WEB

One of the root problems with web styling is the “two-tree problem,” which is the need to maintain separate, interconnected trees for document structure (HTML) and styles (CSS). TailwindCSS solves the two-tree problem with atomic CSS, but its composability is limited due to potential CSS class conflicts. Styled components offer composability, but don't solve the two-tree problem. Inline styles combined with JavaScript can handle most styling needs without running into the two-tree problem.

HOW DOES CHATGPT WORK? AS EXPLAINED BY THE CHATGPT TEAM

ChatGPT works by predicting the next most likely word. After ChatGPT receives text, it breaks down the text into tokens. These tokens are converted into numerical vectors that represent their meaning and relationships to other words. The vectors, called embeddings, are multiplied by a massive matrix of weights (parameters) that have been learned during the training process. The result of the multiplication is a probability distribution over possible next words. ChatGPT samples a word from this distribution to continue the text.

I WROTE MY OWN EDITOR

This author was frustrated with bugs, slowness, and limited debugging features in VSCode. Specifically, slow debugging, a limited watch panel, and a lack of GDB integration led them to create their own text editor. Their new editor prioritizes debugger speed, flexible watch variables, and smooth performance with large files. It already includes core features like syntax highlighting, find functionality, and support for GDB and other debugging protocols.
