Code Bash command prefix detection

This defines risk levels for actions that the ${K4} agent may take. This classification system is part of a broader safety framework and is used to determine when additional user confirmation or oversight may be needed.

Command prefix extraction examples

Examples:

cat foo.txt => cat
cd src => cd

High-Performance Matrix Multiplication

This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).

Intro

Matrix multiplication is a mathematical operation that defines the product of

	import os
	from google import genai
	from google.genai import types

	client = genai.Client(api_key=os.getenv("GEMINI_API_KEY","xxx"))

	# Repalce with the youtube url you want to analyze
	youtube_url = "https://www.youtube.com/watch?v=RDOMKIw1aF4"

	# Prompt to analyze and summarize the Youtube Video

	A micro event loop library implementation from scratch.

	This library provides a minimal but feature-complete asynchronous event loop
	implementation for educational purposes. It demonstrates the core concepts of
	asynchronous programming including:

	- Task scheduling and management
	- I/O multiplexing with non-blocking sockets
	- Timeouts and sleep functionality
