Introduction
Nice to meet you. I am Jeroen and go by the handle h3artbl33d. I am a Unix system engineer during the day, hacker by night. Dutch nationality, late-30s, addicted to coffee and philosophy. I (deeply) value ethics, human rights and respect. In the modern era, values like privacy and freedom are under constant attack. I am hugely opposed to this and try to help out wherever I can for a more humane world.
