The GNU Hackers' Meetings, or GHM, is an annual conference for people interested in the GNU operating system. The conference promotes an informal environment for developers and users of GNU to share experiences and exchange opinions. It usually lasts for three days over which multiple presentations are scheduled. Presentations are allowed to cover a wide range of subjects, both technical and social, related to the GNU project or to the free software movement as a whole. Participation in the conference is subject to prior registration and to the payment of a fee. A limited budget is available to assist those who cannot otherwise afford to attend the conference.
The first GHM took place in Orense, Spain in 2007 and every year it is held in a different location1.
