== Location ==
+
The event will be in the [http://www.delphix.com/company/about-delphix/ Delphix office] in San Francisco:
+
 
+
[https://www.google.com/maps/preview#!q=604+Mission+St.+Suite+400%2C+San+Francisco%2C+CA+94105&data=!1m4!1m3!1d26473!2d-122.4224157!3d37.7867658!4m12!2m11!1m10!1s0x80858062b5adcc23%3A0xd7584093492239e6!3m8!1m3!1d12612!2d-122.3926051!3d37.7913156!3m2!1i1024!2i768!4f13.1 604 Mission Street, 4th floor, San Francisco, CA 94105]
+
 
+
Use the keypad to call Delphix and you will be buzzed in.  Google maps has pretty good [http://goo.gl/QyUHUj directions].  The easiest way to reach the Delphix SF office is by public transportation.  Transportation options, easiest listed first:
+
* BART to the Montgomery St. Station + 3 minute walk
+
* Caltrain to the 4th & King station + 25 minutes walk
+
* Caltrain to the 4th & King station + bus (routes 10, 30, or 45)
+
* drive + park in a lot (costs about $25/day e.g. 41 Tehama Street, 509 Howard Street, or 55 Hawthorne Street)
+
 
+
=== Speaker Info ===
+
'''Note: If you are in the room, you are potentially a speaker.''' This will be done in unconference style, so every attendee should come prepared to present or otherwise lead a discussion or session of up to 45 minutes. You can indicate potential topics in the registration table below.
+
 
+
Equipment available:
+
* Projector
+
* Whiteboard
+
 
+
=== Hackathon ===
+
The goals of the hackathon are:
+
* to get people working with ZFS engineers from outside their normal circles
+
* to start work on some of the [[projects]] we'd like to accomplish
+
Therefore, we should plan to work in small teams of 2-3 engineers.  The team members could be pair-programming, splitting up the work into discrete tasks for each person, or advising / implementing.
+
 
+
==== Hackathon ideas ====
+
''Add your idea and your name below.  Be prepared to explain your idea at the beginning of the hackathon and enlist/entice others to help with it.''
+
* Userland ioctls: support for send/recv (fd operations over the wire)  [[User:mahrens]]
+
* larger (1MB) blocksize: shouldn't be too hard if we ignore performance impact [[User:mahrens]]
+
* dedicated kmem_cache for dedup table entries
+
* stdin / stdout buffer to improve performance of zfs send and receive
+
* ZFS mechanism to override devices' reported sector size (512 vs 4k) (alex @ delphix)
+
* feature flags enhancements for send streams [[User:csiden]]
+
* set owner of all files within a filesystem with a ZFS property [[User:csiden]]
+
 
+
=== Registration ===
+
We are expecting everyone will be there to contribute/participate.
+
 
+
'''The sign up deadline has passed'''.  A few spots are available for late registration.  Mail [mailto:admin@open-zfs.org admin@open-zfs.org] if you would like to attend.
