#Tips: How to become a BlackHat/DEFCON speaker? I have enjoyed speaking many times over the past 5 years at both conferences (likely this time I'll only focus on my Black Hat CFP reviewer role 🧐).

Here some tips to increase your chances of becoming a speaker ⬇️ 1. Choose your research carefully: If you haven't done it yet, think about something unexplored... something that no one else (or few people) have researched so far. Break something new / be innovative, focus on discovering a new technique, new ways to attack or defend something.

I will -briefly- explain how #Docker uses the Linux kernel namespaces to provide isolation. To better understand these concepts, we must think of a container as a process whose children (processes within the container) will run within their parents' namespaces. Thread ⬇️ On Linux, the Docker engine uses the following namespaces:

• UTS: System identifiers isolation
• PID: PID space isolation
• IPC: IPC resources isolation
• NET: network interfaces isolation
• USER: User & Group ID spaces
• Mount namespace: filesystem mount points isolation

Antes de que termine esta semana, ¿Han notado que hay una magazine de la @ekoparty en el kit que les dieron? 😱 Una semana antes recibí invitación para escribir en la misma (gracias) estaba de viaje y no llegué a redactar algo... abajo lo que me hubiera gustado decir... ⬇️ Leí de antemano dos historias de la revista, para tomar de ejemplo, son geniales. Cuando las leí me dí cuenta que mi historia personal era algo distinta, no era mala, pero una perspectiva diferente y me pareció mejor que mi hoja no estuviera allí. Más allá de que estaba de viaje.
