+Introduction
+
+Who is speaking to you?
+ an independent Free Software developer, consultant and trainer
+ 13 years experience using/deploying and developing for Linux on server and workstation
+ 10 years professional experience doing Linux system + kernel level development
+ strong focus on network security and embedded
+ expert in Free and Open Source Software (FOSS) copyright and licensing
+ digital board-level hardware design, esp. embedded systems
+ active developer and contributor to many FOSS projects
+ thus, a techie, who will therefore not have fancy animated slides ;)

+Why am I qualified?
+ The 'Linux community' POV
+ Initiator of OpenEZX project (Linux on Motorola GSM phones)
+ Author of various drivers for embedded hardware
+ The 'embedded Linux done the rigth way' POV
+ Lead System Architect (SW+HW) at Openmoko, Inc.
+ Co-creator of Open Hardware + Software for RFID
+ OpenPCD, OpenPICC, librfid, libmrtd

+Linux is everywhere
+
+Linux is everywhere!
+ Linux mobile phones (Motorola, Openmoko)
+ In-flight entertainment systems
+ Embedded networking gear
+ DSLAMs
+ rack monitoring
+ Public payphones
+ ATM's / PoS / vending machines
+ Now even Fitness gear (Daum Ergometer)

+Strengths of FOSS [0/4]
+
+
+What are the true strengths of FOSS
+ Innovative and creative development
+ Security due to code review / bugreport / patches
+ Long-term maintainable code
+ Stable and reliable systems
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+Nobody has [yet] understood Embedded Linux
+Strengths of FOSS [1/4]
+
+
+Innovative and creative development
+ easy-to-read existing codebase
+ standard (FOSS) development tools
+ thus, easy to modify and add features
+ community will build around great new features/apps
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+Nobody has [yet] understood Embedded Linux
+Strengths of FOSS [2/4]
+
+
+Security due to code review / bugreport / patches
+ because all the code is out there
+ because many people are familiar with existing architecture
+ because code quality requirements usually very high
+ because community process allows quick and fast integration of bugfix
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+Nobody has [yet] understood Embedded Linux
+Strengths of FOSS [3/4]
+
+
+Long-term maintainable code
+ because there's a lot of attention on good software architecture
+ because many developers are familiar with the shared/common API's
+ because code quality requirements usually ery high
+ because all code in mainline gets maintained and updated
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+Nobody has [yet] understood Embedded Linux
+Strengths of FOSS [4/4]
+
+
+Stable and reliable systems
+ because code quality requirements usually ery high
+ because kernel releases are quite frequent
+ because all mainline code is automatically ported to new releases
+
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

+Nobody has [yet] understood Embedded Linux
+Reality Check
+
+ So we should have the perfect world
+ tons of embedded Linux products
+ all of them maitainable, secure, stable
+ encouraging lots of creative work on top of their codebase
+
+ What is the reality
+ tons of embedded Linux products
+ none of the strengths of FOSS present in 99% of them
+

+What does the vendor get
+
+So what do the embedded vendors get?
+ unstable software
+ security nightmares
+ unmaintainable code
+ no innovation
+ no user-contributed bug fixes
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

+Nobody has [yet] understood Embedded Linux
+What does the vendor get
+
+unstable software
+ because their code stinks (low quality)
+ because they patch around problems rather than solving them
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+Nobody has [yet] understood Embedded Linux
+What does the vendor get
+
+security nightmares
+ because they use stoneage forks of the kernel
+ because they never contributed their code mainline
+ because those forks can never be merged back with mainline again
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+Nobody has [yet] understood Embedded Linux
+What does the vendor get
+
+unmaintainable code
+ because they have one fork of the code per device (product)
+ because their code quality sucks
+
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+Nobody has [yet] understood Embedded Linux
+What does the vendor get
+
+no innovation
+ because they try to hide their code (gpl-violations.org)
+ because their R&D environment is non-standard
+ weird cross-toolchains that nobody has seen before
+ weird filesystems with custom patches that nobody knows
+ because they add proprietary components to lock developers from adding features
+ e.g. the entire web-based UI for embedded networking gear
+ binary-only kernel modules that force people to use old kernels with no interesting new features
+ because it is, overall, way too hard to develop on/for their platform
+ because they don't disclose serial console and/or JTAG access
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+Nobody has [yet] understood Embedded Linux
+Reality Check
+
+So why do they still do it?
+ there can only be one conclusion:
+ they never understood the real potential of FOSS
+ all they do is try to compete with what proprietary competitors do
+ they never think about creating platforms, every product is distinct/separate
+ they have no interest in improving their products
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+Nobody has [yet] understood Embedded Linux
+What does the community get
+
+So what does the community get?
+ products that run some crappy fork of Linux somewhere under the hood
+ but which we cannot really touch/modify without a lot of effort
+ we face opposition from the product maker if we want to help him to improve
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+Nobody has [yet] understood Embedded Linux
+TODO
+
+What should they do?
+ stop thinking in terms of selling black boxes
+ defining products that take advantage of the true strength of FOSS
+ compete against the proprietary competition on a level that they can't match
+ give up the idea of defining all aspects of an appliance
+ rather think of building an extensible platforms and let community innovate
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

+Nobody has [yet] understood Embedded Linux
+Outlook
+
+
+Outlook
+ We will see even more embedded Linux, e.g. Mobile phones
+ We will see even more restricted devices (Tivo-ization, DRM for code)
+ which go on _very_ thin ice even with GPLv2
+ which almost completely remove all freedoms of FOSS
+ We have some faint dim light at the end of a very far tunnel
+ e.g. projects like Openmoko, who truly see openness as a feature
