Claude Code Crash Course
A comprehensive, production-grade tutorial for mastering Claude Code in backend development with TypeScript + Express + GraphQL. Based on real-world best practices. Table of Contents Models are good enough now If your output is garbage, your input was garbage. Invest in planning. Introduction Claude Code is Anthropic’s agentic coding tool that lives in your terminal. Unlike traditional chatbots, Claude Code can read files, execute commands, make changes, and work autonomously on problems. This tutorial focuses on maximizing your effectiveness as a backend developer building production systems. Target Audience: Senior backend developers familiar with: Key Insight: Models have become extraordinarily capable. If you’re producing «AI garbage,» it’s because your inputs were…

Filesystem Parallelism for AI Agents
Git worktrees are evolving from a niche feature into an essential primitive for agent-assisted development. They provide filesystem-level parallelism, allowing agentic coding tools to operate concurrently on separate branches, builds, or refactors without sharing a mutable working directory. Why Worktrees Matter Now Modern AI Coding Assistants are becoming increasingly autonomous. They don’t just suggest completions; they execute multi-step plans, run terminal commands, modify multiple files, and orchestrate entire workflows. This autonomy creates a new problem: mutable state collision. When you have multiple AI agents (or one agent handling multiple tasks), they all want to: Without isolation, these operations interfere with each other and with your own work. Git worktrees solve…

Temperaturas, velocidades y voltajes
Con lm-sensors es posible vigilar de manera automática la temperatura de la CPU y otras temperaturas del sistema, las velocidades de los ventiladores y también los voltajes adecuados. Instalación apt-get install lm-sensors Detección sensors-detect Verificar o agregar los módulos detectados anteriormente: vi /etc/modules Insertar los nuevos módulos en el Kernel: service module-init-tools restart Monitoreo automático con Monit De esta manera resulta util tener «scripts» simples que verifiquen, por ejemplo, la temperatura de los Procesadores: vi /etc/monit/conf.d/sensors.conf check program core_0_temperature with path "/PATH/sensor-core-0.sh" group temperature if status > 75 then alert check program core_1_temperature with path "/PATH/sensor-core-1.sh" group temperature if status > 75 then alert Bash Scripts (chmod 500) vi sensor-core-0.sh…
