Wau Holland

The co-founder of the Chaos Computer Club in 1981 and the author of its ethic - Levy's hacker principles extended with two German additions: do not litter in other people's data, and use public data, protect private data.
Holland's club proved its point by doing rather than saying: in 1984 the CCC exploited the Btx videotext system to transfer 134,000 Deutschmarks from a Hamburg bank overnight, then returned it in public with the press watching, forcing the Bundespost to admit a flaw it had denied. That is the CCC method still - technical proof deployed as civic argument - and it is why Germany's hacker scene has spent forty years closer to constitutional politics than to the underground.
