Jack Dorsey construyó el agente de IA local más COMPLETO que existe.

Luego lo donó a la Linux Foundation para que nadie lo controle.

46.4k estrellas. 518 contribuidores. 137 releases. Actualizado hace unas horas.

Se llama Goose y es lo más cerca que he visto de un agente de IA de verdad corriendo en tu máquina.

No solo sugiere código.

Instala dependencias, ejecuta, edita, testea, depura y despliega.

Solo. Sin que le estés mirando.

Lo que lo hace diferente a Claude Code o Codex:

✅ App de escritorio nativa + CLI + API - elige cómo usarlo
✅ Funciona con cualquier LLM: Claude, GPT, Gemini, DeepSeek, Ollama y 15 más
✅ Usa tus suscripciones existentes - sin pagar más APIs
✅ 70+ extensiones MCP: GitHub, Google Drive, bases de datos, navegador y más
✅ Subagentes paralelos - divide tareas complejas y las ejecuta en paralelo
✅ Recipes: guarda flujos de trabajo como YAML y compártelos con tu equipo
✅ Modo adversario integrado - un revisor que detecta inyecciones de prompt y acciones inseguras
✅ Compatible con Claude Code y Codex como proveedores via ACP
✅ Rust nativo. Mac, Linux y Windows. Apache 2.0.

La parte que más me ha flipado:

Puedes conectarlo a Claude Code o Codex como subagente.

Goose orquesta. Ellos ejecutan.

El agente que coordina a otros agentes.

终于找到一个能替代 Wireshark 的开源神器。

GitHub 3.7 万 Star 的 Sniffnet，把网络监控做成了普通人也能看懂的样子。

很多人打开 Wireshark 的第一反应都是：
看不懂，直接关闭。

而 Sniffnet 完全不同。

实时显示上传下载流量、连接主机、访问域名、IP 地理位置，甚至还能查看正在偷偷联网的软件。支持流量过滤、PCAP 导入导出、多网卡监控。

最关键的是界面非常舒服。

不用研究抓包规则，不用学习复杂命令，打开就能看到电脑到底在和谁通信。很多用户直接把它当成 GlassWire 的免费替代品。(Windows Central)

Windows、macOS、Linux 全平台支持，Rust 编写，占用资源极低。(GitHub)

对于经常折腾代理、NAS、Docker、服务器的人来说，这绝对属于装机必备工具。

GITHUB ACABA DE LANZAR LA CERTIFICACIÓN OFICIAL DE UNO DE LOS ROLES TECH MÁS IMPORTANTES DE 2026

→ Agentic AI Developer (GH-600)

Y es la primera vez que trabajar con agentes de IA se convierte oficialmente en una disciplina reconocida de ingeniería.

Ya no hablamos de:
• prompt engineering
• vibe coding
• automatizaciones simples

Hablamos de un nuevo perfil técnico:

→ Agentic AI Developer

La persona que:
• coordina agentes de IA
• construye workflows autónomos
• integra agentes en entornos reales
• supervisa fallos en producción
• evita errores críticos en pipelines CI/CD
• sabe cuándo un agente no es fiable

Antes:
→ “Trabajo con agentes de IA” era difícil de validar.

Ahora:
→ GitHub certifica oficialmente ese skillset.

Y eso cambia el mercado.

Las empresas van a necesitar este perfil.
Pero todavía hay muy pocos developers especializados en ello.

Si ya trabajas con:
• Copilot
• Codex
• Claude Code
• workflows agentic
• automatizaciones con IA

Probablemente ya estés haciendo este trabajo.

GH-600 es la forma de demostrarlo.

Guárdate esto 🔖

Here are 10 GitHub repos that quietly print money while you sleep.

1. Cal. com
Open-source Calendly. Fork it, white-label it, sell to dentists and lawyers for $200/month. The founders hit $5M ARR in 3 years doing exactly this.
Repo → https://t.co/haz8ihRsHm

2. Plausible Analytics
Privacy-first Google Analytics. Self-host it, resell to agencies for $50/month per client. Two founders bootstrapped this to 7 figures.
Repo → https://t.co/RFrcpqTBQ7

3. Ghost

Repo → https://t.co/Z1MdZ5Zapg

4. n8n
Open-source Zapier. Sell automation services for $500-$2,000 per setup. n8n raised $14M because the agency model behind it works.
Repo → https://t.co/hdycABGGc1

5. Supabase
Free Firebase replacement. Build a SaaS in a weekend, charge $29-$99/month. They raised $116M for a reason.
Repo → https://t.co/dFB2QvafA7

Lo que callamos en data

[leopardracer @leopardracer]

I HAVEN’T OPENED A SINGLE BOOK THIS MONTH. CLAUDE READ 34 OF THEM FOR ME

I built a vault in Obsidian, connected Claude and added Notebooklm

went to sleep

woke up with flashcards, mind maps, and an AI that answers from my own notes only

my friends are still highlighting pdfs manually

the only thing separating us is one setup: claude + obsidian + notebooklm

every idea captured. every book processed. zero knowledge lost

if this is the setup you’ve been looking for - like & bookmark so you don’t lose it

[Ronin @DeRonin_]

🚨 SOMEONE JUST KILLED THE COACHING INDUSTRY

a developer spent 22,000 hours building a Personal AI Operating System on top of Claude Code

now anyone with a terminal can install it for FREE

it knows your goals, remembers every decision you've made, and prepares your morning briefing while you sleep

[ the numbers are insane ]:

- hours of dev work in it: 22,000
- sessions logged: 6,000
- time saved per day: 2-3 hours
- GitHub stars: 12,100
- skills built in: 45
- workflows wired up: 171
- safety hooks: 37
- cost to install: $0

[ the science is wild too ]:

no embeddings, no vector databases, no AI magic you can't read

every memory, decision, and context lives in plain markdown files
you read it with cat, search it with ripgrep, version it with git

4 memory types compound over time:

- work memory (active projects, open decisions)
- knowledge memory (domain expertise, research)
- people memory (contacts, companies, relationships)
- learning memory (patterns, mistakes, what works for YOU)

every complex task routes through a 7-step cycle:

OBSERVE → THINK → PLAN → BUILD → EXECUTE → VERIFY → LEARN

privacy is enforced by CODE, not prompts

a hook called ContainmentGuard physically blocks sensitive data from being written outside designated zones

[ the grift opportunity is even wilder ]:

freelancers are already charging $500-2,000 per personal AI setup for executives, founders, and busy operators

one person + one weekend = a consulting business that didn't exist 6 months ago

every AI productivity app you're paying $30/month for is replaceable by 4 hours of setup work and this one repo

API DESIGN ROADMAP

FOUNDATIONS

What is an API → Interface that allows systems to communicate
Types of APIs → REST, GraphQL, SOAP, gRPC
HTTP Basics → Methods (GET, POST, PUT, DELETE), Status Codes
Client-Server Architecture → Separation of concerns
JSON & Data Formats → JSON, XML, Protocol Buffers

REST API DESIGN

REST Principles → Statelessness, Uniform Interface
Resource Naming → Use nouns, not verbs (e.g., /users, /orders)
HTTP Methods →
→ GET → Retrieve data
→ POST → Create data
→ PUT/PATCH → Update data
→ DELETE → Remove data
Status Codes → 200, 201, 400, 401, 404, 500
Versioning → /v1/users, /v2/users

API STRUCTURE & BEST PRACTICES

Consistency → Use standard naming conventions
Pagination → Limit large datasets (?page=1&limit=10)
Filtering & Sorting → Query parameters (?sort=asc)
Error Handling → Clear, structured error responses
Idempotency → Same request → same result
Rate Limiting → Prevent abuse (e.g., 100 requests/min)

AUTHENTICATION & AUTHORIZATION

Authentication → Verify user identity
→ API Keys
→ OAuth 2.0
→ JWT (JSON Web Tokens)
Authorization → Control access levels (roles & permissions)
Secure Endpoints → Protect sensitive routes

API SECURITY

HTTPS → Encrypt communication
Input Validation → Prevent malicious data
CORS → Control cross-origin requests
Rate Limiting → Prevent DDoS attacks
Data Sanitization → Avoid injection attacks
Secrets Management → Secure API keys & tokens

DOCUMENTATION

OpenAPI / Swagger → Standard API documentation
Postman → API testing & documentation
Clear Examples → Request & response samples
Endpoint Descriptions → Explain purpose & usage
Version Documentation → Track API changes

TESTING

Unit Testing → Test individual components
Integration Testing → Test full API flow
Automated Testing → CI/CD pipelines
Load Testing → Handle high traffic
Tools → Postman, Jest, Mocha, Supertest

PERFORMANCE & SCALABILITY

Caching → Redis, CDN
Database Optimization → Indexing, query tuning
Load Balancing → Distribute traffic
Async Processing → Queues (RabbitMQ, Kafka)
Horizontal Scaling → Add more servers

ADVANCED CONCEPTS

GraphQL → Flexible querying
gRPC → High-performance communication
WebSockets → Real-time APIs
API Gateway → Centralized API management
Microservices → Break into smaller services

DEVOPS & DEPLOYMENT

CI/CD → Automate testing and deployment
Docker → Containerize APIs
Kubernetes → Orchestrate services
Monitoring → Logs, metrics (Prometheus, Grafana)
Cloud Deployment → AWS, Azure, GCP

REAL-WORLD BEST PRACTICES

Design First → Plan before coding
Backward Compatibility → Avoid breaking changes
Logging → Track API usage and errors
Throttling → Control traffic spikes
User Experience → Simple, predictable APIs

FINAL LEARNING PATH

Learn HTTP & REST → Understand the basics
Build Simple APIs → CRUD operations
Add Authentication → Secure your API
Document Properly → Use Swagger/Postman
Optimize Performance → Scaling & caching
Deploy to Cloud → Production-ready APIs
