This website contains all the lectures, project materials and tools necessary for building a general-purpose computer system and a modern software hierarchy from the ground up.

The materials are aimed at students, instructors, and self-learners. Everything is free and open-source, as long as you operate in a non-profit setting.

Build and ship infrastructure faster using languages you know and love. Use Pulumi’s open source SDK to provision infrastructure on any cloud.

We make very careful considerations about the interface and operation of the GNU coreutils, but unfortunately due to backwards compatibility reasons, some behaviours or defaults of these utilities can be confusing.

requirements.txt (or “requirements in setup() call”) is not a valid way to manage dependencies — and it hasn’t been for the past 5+ years. If you are still using requirements.txt it shows you need professional help. luckily, i’m a professional.

Let’s go over some bad / good / example practices for living your best python life in 2024.

LibreChat AI is an open-source platform that allows users to chat and interact with various AI models through a unified interface. You can use OpenAI, Gemini, Anthropic and other AI models using their API. You may also use Ollama as an endpoint and use LibreChat to interact with local LLMs. It can be installed locally or deployed on a server.

Test and validate your robots.txt with this testing tool. Check if a URL is blocked, which statement is blocking it and for which user agent. You can also check if the resources for the page (CSS, JavaScript, images) are disallowed.

A vector database indexes and stores vector embeddings for fast retrieval and similarity search, with capabilities like CRUD operations, metadata filtering, horizontal scaling, and serverless.

Generate images from within Krita with minimal fuss: Select an area, push a button, and new content that matches your image will be generated. Or expand your canvas and fill new areas with generated content that blends right in. Text prompts are optional. No tweaking required!

Here’s how I made sense of responsive image content, progressing from simpler to more complicated — and then back to simple.

Using the Yocto Project is fairly easy, until something goes wrong. Without an understanding of how the build process works, you’ll find yourself trying to troubleshoot “a black box”. Here are a few items that new users wished they had known before embarking on their first build with Yocto Project. Feel free to contact us with other suggestions.
