+How to interact with the Free Software Community
+Introduction
+
+Who is speaking to you?
+
+ an independent Free Software developer, consultant and trainer
+ who is a member of the free software community for 10 years
+ who has a background in both the community and the corporate crowd
+ who will therefore not have fancy animated slides ;)
+
+Why is he speaking to you?
+
+ because every working day he suffers the lack of understanding between the community and the business world
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

+How to interact with the Free Software Community
+What is Free Software?
+
+ Software that is
+ available in source code
+ is licensed in a way to allow unlimited distribution
+ allows modifications, and distribution of modifications
+ is not freeware, but copyrighted work
+ subject to license conditions, like any proprietary software
+ READ THE LICENSE
+
+What is Open Source?
+ Practically speaking, not much difference
+ Remainder of this presentation will use the term FOSS (Free and Open Source Software)
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+How to interact with the Free Software Community
+What is the FOSS Community?
+
+ Diverse
+ any individual can contribute
+ no formal membership required
+ every project has it's own culture, rules, ...
+ International
+ the internet boasted FOSS development
+ very common to have developers from all continents closely working together
+ Evolutionary
+ developers come and go, as their time permits
+ projects evolve over time, based on individual contributions
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+How to interact with the Free Software Community
+People / Groups involved
+
+ Really depends on size of projects
+ Small projects often a one-man show
+ Bigger project have groups / subgroups
+ Common Terms / Definitions
+ Maintainer
+ The person who formally maintains a project
+ Core Team / Steering Committee
+ A group of skilled developers who make important decisions
+ Subsystem Maintainer
+ Somebody who is responsible for a particular sub-project
+ Developer Community
+ All developers involved with a project
+ User Community
+ Users of the software who often share their experience with others
+
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+How to interact with the Free Software Community
+Development Process
+
+ "Rough concensus and running code"
+ Decisions made by technically most skilled people
+ Reputation based hierarchy
+ Direct Communication between developers
+ Not driven by size of a target market
+ Release early, release often
+
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+How to interact with the Free Software Community
+Motivations
+
+ gaining reputation (like in the scientific community)
+ gaining development experience with real-world software
+ solving problems that the author encounters on his computer
+ fighting for Free Software as ideology
+ work in creative environment with skilled people and no managers ;)
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+How to interact with the Free Software Community
+FOSS Community likes
+
+ generic solutions
+ portable code
+ vendor-independent architecture
+ clean code (coding style!)
+ open standards
+ good technical documentation
+ raw hardware, no bundle of hardware and software sold as solution
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+How to interact with the Free Software Community
+FOSS Community dislikes
+
+ monopolistic structures
+ e.g. intel-centrism
+ closed 'industry forums' with rediculous fees
+ e.g. Infiniband, SD Card Association
+ standard documents that cost rediculous fees
+ NDA's, if they prevent development of FOSS
+
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+How to interact with the Free Software Community
+Weak Points of FOSS
+
+ often way behind schedule (if there is any)
+ already too late when projects start
+ started when there already is a real need
+ often a lack of (good) documentation
+ programmers write code, not enduser docs...
+ strong in infrastructure, weak in applications
+ traditionally developers interested in very technical stuff
+
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

+How to interact with the Free Software Community
+Practical Rules
+
+ 1. Much more communication
+ It's not a consumer/producer model, but cooperative!
+ Before you start implementation, talk to project maintainers
+ It's likely that someone has tried a similar thing before
+ It's likely that project maintainers have already an idea how to proceed with implementation
+ Avoid later hazzles when you want your code merged upstream
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

+Practical Rules
+
+ 2. Interfaces
+ If there is a standard interface, use it
+ If insufficient: Don't invent new interfaces, try to extend existing ones
+ If there is an existing interface in a later (e.g. development) release upstream, backport that interface
+ Don't be afraid to touch API's if they're inefficient
+ Remember, you have the source and _can_ change them
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

+Practical Rules
+
+ 3. Merge your code upstream
+ Initially you basically have to create a fork
+ Development of upsteram project continues sometimes at high speed
+ If you keep it out of tree for too long time, conflicts arise
+ Submissions might get rejected in the first round
+ Cleanups needed, in coordination with upstream project
+ Code will eventually get merged
+ No further maintainance needed for synchronization between your contribution and the ongoing upstream development
+ Don't be surprised if your code won't be accepted if you didn't discuss it with maintainers upfront and they don't like your implementation
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

+Practical Rules
+
+ 4. Write portable code
+ don't assume you're on 32bit CPU
+ don't assume you're on little endian
+ if you use assembly optimized code, put it in a self-contained module
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+How to interact with the Free Software Community
+Practical Rules
+
+ 5. Binary-only software will not be accepted
+ yes, there are corner cases like FCC regulation on softradios
+ but as a general rule of thumb, the community will not consider object code as a solution to any problem
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

+Practical Rules
+
+ 6. Avoid fancy business models
+ If you ship the same hardware with two different drivers (half featured and full-featured), any free software will likely make full features available on that hardware.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

+Practical Rules
+
+ 7. Show your support for the Community
+ By visibly contributing to the project
+ discussions
+ code
+ equipment
+ By funding developer meetings
+ By making cheap hardware offers to developers
+ By contracting / sponsoring / hiring developers from the community
+
