I'm a 22 years computer science student. My favorite open source operating system is OpenBSD and I pass much of my freetime hacking on it. I develop in C, C++, Python, Java, ksh, Php, SQL, Css, xHtml. I like mixing music, electro, tek, hardteck. I like to hack and use metasploit, scapy, nmap, play with pf and ipsec. I play with packet filter, ssh, ipsec, squid, postfix, OAMP, postgresql, ldap. My favorite IDS is Prelude, using snort and others as sensors.
