+# Your mission in this World?
+
+  * Astronaut?
+  * Professor?
+  * Mother?

+
+# Passion
+
+  * ~~Missions~~
+  * Passions!
+  * Curiosity!
+
+# Key elements in life (and computer life)
+
+  * Passions
+  * Curiosity
+  * Home
+  * Trust
+
+# Home
+
+  * Where you are **safe**
+  * Where you can **store** goods
+  * Where you can **fumble** and experiment
+
+# Trust
+
+  >* trust: feeling comfortable as guest in another home
+  * proper trust == mutual trust
+
+# Healthy environment
+
+  * everyone has a **home**
+  * everyone is driven by **passions**
+  * everyone finds mutual **trust** in some others

+  * Localized into **100+ languages**
+  * Neighbourhood of **friendly** users
+  * Maintained by **passionate** developers
+  * You are **welcome to share** your passions as an **equal peer**
+
+# Debian - the universal Operating System
+
+  * Free Software
+  * 100% created and governed by volunteers
+  * Very very stable
+  * Very very big
+  * Flexible...
+
+Debian is "the universal Operating System"
+
+# Debian - very flexible...
+
+> * Flexible: good
+  * Very flexible: very good
+
+# Debian - **too** flexible!
+
+  * Flexible: good
+  * ~~Very flexible: very good~~
+  * Very flexible: very confusing!
+
+Debian is maybe too flexible: confusing or even scary...
+
+# Debian - ways to simplify
+
+  1. Tolerate it: Use it as-is
+  1. Remove choice: Use e.g. Ubuntu
+  1. Use a Debian Pure Blend
+
+# Debian - simple if generic defaults are ok
+
+  * Mainstream (but not too new) hardware
+  * GNOME desktop
+  * Iceweasel web browser (= Firefox)
+  * Exim MTA
+  * Apache web server
+  * MySQL database server
+
+Debian *is* simple - if you like the defaults.
+
+# Ubuntu - your new home?
+
+  * Nicer than Debian - if you like the defaults
+
+# Debian Pure Blend - Debian for a specific purpose
+
+a subset of Debian configured to
+support a particular target group out-of-the-box.
+
+# Debian Pure Blend - current blending projects
+
+  * Debian Jr
+  * Debian Med
+  * Debian Edu
+  * Debian Science
+  * Debian EzGo
+  * BrDesktop
+  * Debian Accessibility
+  * Debian Lex
+  * DebiChem
+  * Debian GIS
+  * Debian Multimedia
+
+# Deebian Pure Blends - future blends
+
+  * FreedomBox
+  * Debian LAN
+
+# Home alone...
+
+  * Calls are lost when you are out
+  * Friends cannot see your "wall" when you are out
+
+# A bigger house for all your devices
+
+  >* Your desktop/laptop
+  * Your phone
+  * Another computer at school or at a friend...
+
+# Have a butler!
+
+  * Lets friends in, holds back random guests (=spam)
+  * shows guests what they are allowed to see (=wall)
+  * ...
+
+# Example: Store and play music
+
+  >* Chat with butler
+  * Make backup of your computer/phone
+  * → Butler notice music files, and suggests starting jukebox
+  * Chat with a friend
+  * → Butler suggest sharing with friend what you are listening to
+  * Friend also share jukebox status
+  * → Butler

+  * Calculates new trust paths
+  * Suggests use of the tools

+
+# Tech - tasks involved
+
+  * extra software → into Debian officially
+  * manual configurations → preseeding
+  * maybe create temporary dirty hacks
+  * maybe use/create reusable tweaks
+  * eliminate dirty hacks and tweaks
+  * convince others in Debian to add as tasksel task
+
+# Tech - blends-dev
+
+Tool to help maintain package lists and prospective packages.
+
+Example: <http://debian-med.alioth.debian.org/tasks/psychology>
+
+# Tech - dirty tricks
+
+Avoid configuration files...
+
+  * config.d folders
+  * databases
+  * networked data
+
+# Tech - tweaks
+
+Reusable scripts compatible with one or more of...
+
+  * FAI
+  * hands-off at http://hands.com/d-i/
+  * CFengine
+  * Puppet
+
+# Tech - good style
+
+  * Aptitude
+  * debconf
+  * Config::Model
+
+# Tech - When is it "Pure"?
+
+When all is in Debian, with no dirty tricks:
+
+  * package selection(s)
+  * customizations
+  * installation
+
+# Team - getting involved
+
+  * identify and isolate tweaks at your own system
+  * register missing software - on wiki page or (better!) in Debian BTS
+  * write documentation
+  * write the dream of how things ought to work
+  * wite how details work now
+  * discuss downstream (i.e. with users and subdistros) how things work /
+    should work
+  * discuss upstream (i.e. with authors) what is possible now / soon
+
+# Team - getting involved II
+
+  * write intro for peer enthusiasts
+  * decide and document ideal formats  - translations, graphics etc.
+  * prioritize pending tasks - of various kinds to encourage many
+    different contributions
+  * document where it is ok to ask beginners' questions
+  * document if beginners can ask for a mentor
+
+# Team - getting involved III
+
+  * make illustration
+  * make screendumps
+  * make fan graphics
+  * make desktop backgrounds, CD covers, stickers, etc.
+  * Register the project as a DOAP file, and maybe at Ohloh and Freshmeat
+    etc.
+  * Register and maintain relevant Debtags
+
+# Team - getting involved IV
+
+  * Translate package descriptions
+  * Translate debconf dialogs
+  * Translate upstream code
+
+# Team - getting involved V
+
+  * Help integrate contributions from graphics artists, translators and
+    others
+  * document decision processes of the team (and Debian and upstreams?)
+  * document workflows in teams
+  * insist on transparency - not only for code!
+
+# Team - Continuous status checks
+
+  * Ask users about their needs - you will forget over time!
+  * Ask teams about their tasks - each participant has slightly different
+    perception of the common vision and status
+  * Ask upstreams about use: perhaps potentials are missed, or code or
+    persons feel as being abused
+
+# Debian Pure Blends - Future
+
+ * debconf dontcare vs. explicit choice of default option
+ * debconf query mechanism (and fill buffer from live system)
+ * APT explicit choice of alternate dependency/recommendation
+ * APT dontcare vs. explicit choice of default dependency/recommendation
+ * Config::Model - semantic configfile handling
+
+# Final words...
+
+Be **passionate**!
+
+**Share** your passion!
