OpenBSD
In December 1994, de Raadt was asked to resign his position as a senior developer and member of the NetBSD core team, and his access to the source code repository was revoked. The reason for this is not wholly clear, although there are claims that it was due to personality clashes within the NetBSD project and on its mailing lists. De Raadt has been criticized for having a somewhat abrasive personality: in his book, Free For All, Peter Wayner claims that de Raadt "began to rub some people the wrong way" before the split from NetBSD; while Linus Torvalds has described him as "difficult"; and an interviewer admits to being "apprehensive" before meeting him. Many have different feelings: the same interviewer describes de Raadt's "transformation" on founding OpenBSD and his "desire to take care of his team," some find his straightforwardness refreshing, and few deny he is a talented hacker and security "guru".
In October 1995, de Raadt founded OpenBSD, a new project forked from NetBSD 1.0. The initial release, OpenBSD 1.2, was made in July 1996, followed in October of the same year by OpenBSD 2.0. Since then, the project has followed a schedule of a release every six months, each of which is maintained and supported for one year.
