React Hooks: The Matrix of useState and useEffect

The Quest Begins (The "Why") I still remember the first time I tried to make a component “remember” something. I had a simple counter that needed to increment every time a button was clicked, and I wanted to fetch some data when the component showed up. My first instinct? Reach for class components, sprinkle in this.state , and call componentDidMount and componentDidUpdate like I was casting…

The article discusses the evolution of React components from class-based architecture to functional components using Hooks. The author recounts their initial struggle with class components, where they found the boilerplate code and scattered lifecycle methods cumbersome. After discovering Hooks, specifically useState and useEffect, the author found a new way to structure their components. useState provides a simple and intuitive way to manage local state, while useEffect allows for handling side effects, such as fetching data or updating the document title.

The author emphasizes the benefits of grouping related logic together, isolating each piece of state and side effect, and making the component code more readable and maintainable. By using Hooks, the author can write cleaner and more modular code, avoiding the spaghetti western-like mess that can arise from duplicating patterns across lifecycle methods.

Your Keras model config can contain a marshalled Python code object

Most conversations about malicious ML artifacts stop at pickle. That's understandable — torch.load calling __reduce__ is the canonical example, and it's the one everybody has read about.

  • Keras models can embed Python code objects within their configuration
  • Unmarshalling .keras files to inspect code is unsafe
  • Aisbom v1.3.0 identifies Lambda layers and embedded code as CRITICAL risks
