Hackathons
</h2>
<hr>

<p>
In June of 1999, OpenBSD held the first hackathon.  In the months
leading up to this, either Theo or Niels Provos had coined this new
word <dfn>hackathon</dfn>.  A bunch of developers from around the world congregated
into a house in Calgary, and within the week had the first IPv6 and IPSEC
stacks completely integrated into an operating system... an industry
first.. an accidental scrape in a hardwood floor commemorates the event.

<p>
In succeeding years, the OpenBSD development process has benefited
greatly from holding more of these events.  In our form, hackathons
do not have talks, nor a specific schedule.  People will arrive at
a hackathon to work for a straight stretch of time on the projects
they wish to, in the same room as the people who they need to talk
to about their ideas.  Hackathons are about writing code.  At hackathons
there is an attempt to get new changes into the source tree quickly.
Since people from many different timezones are in the same room,
development is almost around the clock.  Developers sometimes joke
about returning home without jet-lag.

<p>
Hackathon attendees come by invitation only.  Some new people in
the community who show promise are sometimes invited to see if they
have what it takes.  However, hackathons are not developer training
events.

<p>
The event space and accommodation is typically funded by
<a href="donations.html">donations to the OpenBSD Project</a>, or
by the <a href="https://www.openbsdfoundation.org">OpenBSD Foundation</a>,
however most developers pay for their own travel.  The facilities
are always chosen to be highly economical; generally near Universities
or in cheaper locales.  If anyone wants to help us <strong>FUND ONE OF THESE
EVENTS OR A DEVELOPER'S TRAVEL</strong>, please contact Theo de Raadt (who
generally has the most knowledge about upcoming options), or directly
offer travel expenses to a developer for the next event.  General
financing is more interesting, but we will entertain offers for free
locations as well.

<p>
Here are some details about past and future events, also showing
a part of the artwork from the event T-shirt (if there was one made).
The shirts are only given to people who attend the event, and are
worn with pride.  Every shirt contains at least one developer in-joke,
so don't worry if you can't understand the shirt.  Just enjoy them.
