“I have many subsystems, but I want one easy function that hides how messy they are.” The Facade pattern is a classic design pattern used to provide a simple, unified API on top of one or more complex subsystems. In Rust, where types, modules, and ownership models naturally encourage small and well-defined components, it’s common […]
Note, this article is written by me, the human who wrote the code! If you use LLMs you will need to check their output, else hallucinations, wrong answers, and unhappy customers. Note, this code is all open source, aka “Free” I built “evaluate” as the server, which does the calls to the LLMs, and you […]
What is x.max(0.0)? x.max(0.0) returns the maximum value between x and 0.0. It’s Rust’s method for finding the larger of two numbers. ReLU Worked Examples: ReLU (Rectified Linear Unit) formula: ReLU(x) = max(0, x) This means: Here are concrete examples: Visual Example: Why ReLU is Powerful: Comparison with Sigmoid: ReLU is like a one-way gate: […]
CANDLE Handles all the heavy mathematical lifting – matrix multiplications, softmax, broadcasting, gradients, and hardware acceleration. Think of it like “NumPy” for AI, for Rust! Candle lets you run ML models entirely inside a Rust program, without Python or a separate service like Ollama. The Magic: When you write something like q.matmul(&k.t())?.softmax(D::Minus1)?, CANDLE automatically: So […]
Sometimes in Rust, we want to tag a type with extra information without actually storing that information at runtime. That’s where phantom types and PhantomData come in. What is PhantomData? PhantomData<T> is a special zero-sized type in Rust that tells the compiler “I want to use this type T in my struct, but I don’t […]
What are they, why do we use them, how are they different to trait bounds? ✅ Why you’d need it: You’d use a blanket trait when: 🔍 Tell-tale signs you need one: Without a blanket trait annoying… With a blanket trait Why not just one generic function instead of a trait? That avoids repeating code.But […]
Upgrade Webpack & Dependencies (Recommended Long-Term) 🔧 Problem: You’re hitting the classic OpenSSL incompatibility issue that started affecting many Webpack 4/5 projects when Node.js v17+ introduced changes to the OpenSSL crypto defaults. Node.js v17 and later uses OpenSSL 3.0, which by default disables legacy algorithms used in Webpack for hashing.Fix it by upgrading webpack Then […]
Once you have Docker installed, you can simply run Qdrant with an API key For testing, just make your own value without the API key you chose -> Qdrant Rust Client Create a “collection” and “upsert” some data Do a vector search Filter search Prepare a model to do embeddings with Qdrant (fastembed) *Each model […]
This tutorial demonstrates the powerful combination of Factory and Builder patterns in Rust. It’s useful to know, and also be able to recognize. Key Concepts Covered: Factory Pattern: The DatabaseType enum acts as a factory that knows how to create different database implementations. It encapsulates the creation logic and provides a clean interface for object […]
