Building a Second Brain with Claude and Obsidian
A complete step-by-step tutorial on Andrej Karpathy’s LLM Wiki method Karpathy’s LLM Wiki gist on GitHub has been starred over 5,000 times and forked just as many. Most of those people will never actually build the thing. This tutorial exists for the people who will. Original reference: https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f Why this isn’t another RAG tutorial When…

Architectural Implementation Blueprint: Deploying the Multi-Layer Claude Code Framework
1. The Paradigm Shift: From Chatbot to Senior Teammate Deprecate the “chatbot” mental model in favor of the stateful runtime primitive. In high-performance engineering environments, viewing Claude Code as a conversational assistant is a Level 1 bottleneck. To achieve Level 4 architectural maturity, you must treat Claude Code as a comprehensive agent development kit (ADK)…

I Tested the New GPT-5.5 Model for You (for 2 Hours) and This is My Take
The “Spud” Has Landed: Beyond the Poem The AI “jagged frontier” just moved again, and this time it didn’t come with a flashy keynote. OpenAI surprise-dropped GPT-5.5 (codenamed “Spud”), and the technical community is scrambling to figure out if this is a true step-change or just another incremental polish. I’ve spent the last two hours…

How to Never Hit Claude’s Rate Limits
It’s 11 AM and Claude just told you to come back later. You’re mid-draft on a client deliverable, or halfway through debugging a function that was almost working. Sound familiar? Here’s the thing: the limit isn’t the problem. Your habits are. Most people default to the biggest model for everything, leave token-hungry features running in…

Software 3.0 : The Evolution of Software in the Era of AI
From Code to Weights to Prompts: A Practitioner’s Guide to Software 3.0 By Sami BELHADJ Introduction: The Machine Is Finally Listening In the past three years, software development has hit an inflection point unlike anything the industry has seen since the transition from mainframes to personal computing. Large language models have exploded in popularity at…

Specification-Driven Development (SDD) : Why the Best Code You’ll Ever Write Isn’t Written in Code
1. The Perpetual Gap: The Documentation Tax We have long suffered the “Documentation Tax”—that inevitable decay where the Product Requirements Document (PRD) becomes a tombstone for original intent the moment the first line of code is written. In the traditional cycle, we treat specifications as “discarded scaffolding”: temporary structures used to erect the “real” building…

La Fin de la Suprématie du Code : Pourquoi la Spécification est devenue votre Seule Source de Vérité
1. Introduction : Le “Code est Roi” est mort Pendant des décennies, l’ingénierie logicielle a vécu sous un dogme immuable : le code est la vérité absolue. Tout le reste — documents d’exigences, schémas d’architecture, commentaires — n’était que littérature, souvent obsolète avant même d’être lu. Nous avons accepté ce fossé entre l’intention humaine et…

L’IA ne va pas simplement coder à votre place : elle va démanteler votre cycle de développement
L’illusion de l’assistant : Invalider les postulats de la gouvernance logicielle Nous vivons un paradoxe structurel. La majorité des organisations traitent l’intelligence artificielle comme une simple extension de leurs outils existants — un assistant de saisie ou un générateur de documentation plus performant. Pourtant, l’IA n’est pas une simple accélération de l’existant ; elle invalide…

AIDLC : Why Your Software Development Life Cycle is Broken: 5 Impactful Truths About the New AI-Native Era
For decades, the Software Development Life Cycle (SDLC) has operated with a familiar, predictable rhythm. Product managers dictate requirements, engineers write the code, and QA teams test the result. This was a deterministic system designed for a world of static logic where identical inputs yielded identical outputs. That era is over. We are currently trapped…
