Have you been trying to learn how compilers and programming languages work? Then come along! Let’s make a compiler that goes all the way from source to assembly from scratch—no shortcuts This book will teach you enough compiler theory and assembly programming to get going. It uses a subset of TypeScript that reads like pseudocode and targets ARM 32-bit instruction set.

Imagion composing a BMP image by hand, or writing a executable file manually? What kind of knowledge need to do that? Mastery of computer programming unlocks power, flexibility, speed, and debugging prowess across all of your work. We will learn in depth what you use every day, by exploring memory, instructions, syscalls, functions, structure and cognition.

In my security research I often come across weird quirks and behaviours that aren’t particularly useful beyond a neat party trick. It’s always a good idea to keep track of them though, perhaps one day they’ll be just the missing piece you need.

Have you ever want a search to find similar image? In this blog we’ll build a basic image search engine using Postgres. We’ll use a pre-trained model to generate embeddings for images and text, then store those embeddings in Postgres. The pgvector extension will enable us to conduct similarity searches on these embeddings using both images and raw-text as queries.

Part 6 of an AI Engineering open-source models tutorial series. We focus on RAG on this article. A RAG pipeline is what allows your AI model(s) to leverage the knowledge of your private/corporate data in its inference. It consists of the following stages: loading, indexing, storing, querying and evaluation.

In JavaScript, more often that not you may want to cancel a request? Imagine an auto-completed, when user type more, you may want to cancel the previous request, there is no point to get them. AbortController is a global class in JavaScript that you can use to abort these fetch request. And also anything else, not just http request.

Parent-child relationship happens a lot in context of web dev. Even harder when it’s nested. Example, nested comment. In this shortarticle we look at the ltree Postgres extension to store and retreive that data type.

This post is part of an ongoing series about Chrome’s efforts to improve the DevTools Performance panel. Learn about these tools to help analyze performance of our front-end app. In this post we’ll take a closer look at each of the new features: Real-time local Core Web Vitals performance, Real-user experience data, Recommendations to configure your local environment, Information to help you reproduce issues.

Websocket bandwidth is especially chatty for Discord because they need to broadcast the message to all connection client. Also, decreasing bandwidth usage would lead to a more responsive experience.
