In 1993, Assange was involved in starting one of the
first public internet service providers in Australia,
Suburbia Public Access Network.[8][24] Starting in 1994,
Assange lived in Melbourne as a programmer and a
developer of free software.[22] In 1995, Assange wrote
Strobe, the first free and open source port scanner.[25]
[26] He contributed several patches to the PostgreSQL
project in 1996.[27] He helped to write the book
Underground: Tales of Hacking, Madness and Obsession on
the Electronic Frontier (1997), which credits him as a
researcher and reports his history with International
Subversives.[28] Starting around 1997, he co-invented the
Rubberhose deniable encryption system, a cryptographic
concept made into a software package for Linux designed
to provide plausible deniability against rubber-hose
cryptanalysis;[29] he originally intended the system to
be used "as a tool for human rights workers who needed to
protect sensitive data in the field."[30] Other free
software that he has authored or co-authored includes the
Usenet caching software NNTPCache[31] and Surfraw, a
command-line interface for web-based search engines. In
1999, Assange registered the domain leaks.org; "But", he
says, "then I didn't do anything with it."[32]
Maybe there should be a running list of where Assange has contributed to because all of these posts are superfluous and don't really have much substance.
