📂 Minimize allocations in Go

A collection of tips for when you need to minimize the number of allocations in your Go programs.

Use the go profiler to identify which parts of your program are responsible for most allocations.

⚠️ Never apply these tricks blindly (i.e. without measuring the actual performance benefit/impact). Most of these tricks cause a tradeoff between reducing memory allocations and other aspects (including e.g. higher peak memory usage, higher CPU usage, lower maintainability, higher probability of introducing subtle bugs). Only apply these tricks if the tradeoff in every specfic case is globally positive.

Building Complex Drag & Drop Visual AI Workflows with React Flow and Python Flask

Created by @rUv

This tutorial demonstrates how to create a Python Flask implementation with React Flow to build complex AI workflows, reasoning systems, and comprehension modeling tools.

React Flow is a powerful open-source library for building interactive node-based interfaces in React applications. Its flexibility and extensibility make it an excellent choice for creating sophisticated AI applications.

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
