The Great LLM Code Optimization Battle: 8 AI Models, 1 Function

The Challenge

What happens when you pit the world's most advanced AI models against each other in a code optimization challenge? I decided to find out by asking 8 different large language models to optimize a single PHP function - and the results were fascinating, surprising, and sometimes hilariously broken.

The prompt was simple and identical for all contestants:

"optimize this code: php 7.4"

SSH Post-Quantum Cryptography Configuration Guide

This guide explains how to configure SSH to use post-quantum cryptography and suppress related warnings.

Understanding the Warning

When connecting via SSH, you might see:

** WARNING: connection is not using a post-quantum key exchange algorithm.
** This session may be vulnerable to "store now, decrypt later" attacks.

Summary: Building Resilient Background Processing in Laravel

This talk by Haris Weftopoulos provides a deep dive into Laravel's queue system, moving from fundamental concepts to advanced production-ready strategies. The key takeaway is that queues are essential not just for performance, but for building reliable and scalable applications.

---

1. Core Concepts & Why You Should Use Queues

• The "Why": Queues decouple time-consuming tasks (like sending emails, processing images, calling third-party APIs) from the user's web request. This results in:
• Performance: Instant-feeling responses for the user.

Andrej Karpathy: Software Is Changing Again

Summary

• 🧠 Three Generations of Software: Karpathy introduces Software 1.0 (code written by humans), 2.0 (neural network weights), and 3.0 (prompts for LLMs). Software is now written in natural language, allowing for broader access and faster iteration.

• 🚗 Neural Nets Replacing Code: Using Tesla’s Autopilot as an example, he shows how neural nets gradually replaced traditional code, signifying a profound industry transition.

• 🧮 LLMs as Utilities and OSs: LLMs are described as akin to utilities (like electricity) due to centralized access, but function like operating systems, orchestrating memory and tools for problem-solving.

JetBrains Error Fixing Workflow

When fixing code errors in JetBrains IDE:

1. Use your own file tools, NOT JetBrains tools: Always use the Read, Edit, Write, Glob, and Grep tools for file operations. Do not use JetBrains file editing tools like mcp__jetbrains__replace_specific_text or similar.

2. Check errors first: Use mcp__jetbrains__get_current_file_errors to get the current list of errors in the open file.

3. Read the file: Use the Read tool to understand the file content and locate the problematic code.
