This article explains the fundamental mechanisms behind image generation AI (such as text-to-image models) for non-engineers. As generative AI rapidly evolves, the goal is to provide an intuitive understanding of the underlying principles. For a more technical deep-dive, please refer to the foundational paper behind Stable Diffusion: (arXiv link) High-Resolution Image Synthesis with Latent Diffusion Models Images as Digital Data First, let’s look at how computers represent images as data. An image is an aggregation of pixels. A 1000 x 1000 image consists of 1,000,000 pixels. In standard digital imagery, each pixel is stored as an 8-bit integer (a number from 0 to 255), meaning any digital image is simply a collection of numerical values: ...

This article is for Day 6 of the “Wall Advent Calendar 2021”. Why Build a Home Theater?

Unlike homeowners, tenants face strict constraints: ...

Goal When building a Docker image, we often install various C++ libraries. However, when working inside the container as a non-root user, header files may not be automatically included in the default search paths, which can be inconvenient. We want to configure this neatly during the image build (inside the Dockerfile). However, the ENV directive only sets environment variables directly or for the root context, and might not always propagate properly to custom non-root users added later in certain shell sessions. ...

Why Build a Home Theater? Have you ever heard of a home theater? It’s literally a theater in your home. Enjoying movies and games on a massive screen is simply incredible. While it might sound daunting to set up, it’s actually much easier to achieve than you might think. There is no strict definition of a home theater. Generally, it refers to a setup with a reasonably large screen accompanied by a solid speaker system (such as surround sound). Broadly speaking, setups are divided into TV-based and Projector-based configurations, each with its own pros and cons: ...
