+% Debian Pure Blends
+% Jonas Smedegaard
+% Khammam, October 20th, 2011
+
+# Overview
+
+ * Debian is generic - Blends are specific
+ * Purity: all is Debian
+ * Why bother?
+ * Technical details
+ * Team, community, users
+ * Future
+
+# Debian - the universal Operating System
+
+ * Stable
+ * Flexible
+
+Debian is the universal Operating System.
+
+Goal
+ : Usable everywhere
+
+# Debian - very flexible...
+
+> * Flexible: good
+ * Very flexible: very good
+
+# Debian - **too** flexible!
+
+ * Flexible: good
+ * ~~Very flexible: very good~~
+ * Very flexible: very confusing!
+
+Debian is too flexible: confusing and to some even scary!
+
+# Debian - ways to simplify
+
+ 1. Keep things as-is - educate users instead
+ 1. Remove choice
+ 1. Provide multiple defaults
+
+# Debian - simple if generic defaults are ok
+
+ * Mainstream (but not too new) hardware
+ * GNOME desktop
+ * Iceweasel web browser
+ * Exim MTA
+ * Apache web server
+ * MySQL database server
+
+Debian *is* simple - if you happen to like its defaults.
+
+# Debian Pure Blend - Debian for a specific purpose
+
+Debian Pure Blend (in short DDD): a subset of Debian configured to
+support a particular target group out-of-the-box.
+
+Goal 1
+ : Turn Debian into the distribution of choice for a specific target
+ group
+Goal 2
+ : Advertise this fact to the world to attract users and developers
+
+# Debian Pure Blend - technical parts
+
+ * package selection(s)
+ * customizations
+
+The concrete work to include as packages with official Debian.
+
+# Debian Pure Blend - reality parts
+
+ * goals & noise about progress
+ * package health + encourage additional software packaging
+ * passion & patience
+ * good relations with Debian package maintainers, competitors, and upstream authors
+ * good relations with users
+
+Surrounding work making a Blend relevant.
+
+# 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
+
+Projects working on Blends - some pure, some not (yet)...
+
+# Debian Pure Blends - all Debian
+
+ * **D**ebian packages - selections (e.g. for tasksel to pick up)
+ * **D**ebian configuration - use of policy-compliant package-provided interfaces
+ * **D**ebian distribution media - installing via Debian itself
+
+DDD
+ : **Debian** packages **Debian** configured from **Debian** distribution
+
+# Debian Pure Blends - why bother?
+
+Nice on paper with ideals and priciples, but...
+
+What's in it for me?!?
+
+# Debian Pure Blends - downsides
+
+ * **annoying** - Debian package maintainers may not like proposed changes
+ * **slow** - stable distribution is released infrequently
+ * **rigid** - all contributions must match Debian Free Software Guidelines
+ * **complex** - packages must obey Debian Policy
+
+# Debian Pure Blends - Benefits
+
+ * backed by Debian - help, bug tracking, translations, etc.
+ * teamwork - others might help you refine and maintain your setups
+ * common structures - others might take over if you loose interest
+
+# Tech - Debian support overloading choices
+
+ * Debian installer
+ * tasksel
+ * debconf
+ * aptitude
+
+# Tech - examples of non-pure blending
+
+ * include non-Debian packages or non-packaged stuff
+ * include Debian packages from different Debian suite
+ * configure system other than via Debian package installation
+ * install using non-Debian media
+
+You don't own your system - you provide one for others to own.
+
+So don't refine it like a (sloppy) user: Handle it like a Debian developer!
+
+# Tech - Debian, generic setup
+
+ * select package profile(s)
+ * install
+
+# Tech - Debian, hand-tuned
+
+ * select package profile(s)
+ * select additional packages
+ * install
+ * (re)configure packages
+
+# Tech - Debian, auto-tuned
+
+ * pre-seed package selection
+ * pre-seed package configurations
+ * install
+ * (re)configure non-debconf packages
+
+# Tech - Debian Pure Blend = generic
+
+ * select blend profile
+ * install
+
+# 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
