+#+begin_notes
+How do we find the program that we are looking for?
+Let me rephrase: How do we find the program that does the job for us?
+
+What do we expect from computers?
+We don't expect to program them: we expect to run a program and get the job 
done.
+
+User experience question: when first confronted with a computer, how do we know
+which program to run? => Tribal knowledge (e.g. VLC is famous because it's 
famous).
+
+Speak for Guix-specific improvements, but also more general research.
+#+end_notes
+
+* Dotfiles, or "Yet another home-made service"
+
+#+TODO: Take data from GitHub, gitlab "dotfiles" repositories
+??? "dotfiles" repositories across GitHub, GitLab...
+
+Average of ??? lines.
+
+#+begin_notes
+Show of hands: who has spent too much time on their dotfiles?
+
+What is a dotfile really?  It's just another home-made service.
+
+Just like a program, it gets the job done.  And when start thinking this way, 
we
+start realizing that it's only a blurred line between services and packages.
+#+end_notes
+
+* First-class services
+
+Or "The end of dotfiles!"
+
+#+begin_notes
+My claim: we can put an end to dotfiles!
+
+Rephrase: An end to "egoistic un-reusable dotfiles".
+
+Everyone can start upstreaming their dotfiles configurations and share them.
+
+Dream: Just need to declare which program and services you want to use and your
+are done.  This could tailor to your most specific needs.
+
+Service example: daily backup of my data with rsync+ssh/vpn.
+#+end_notes
+
+* Example
+
+# TODO: Finish service example
+#+begin_src scheme
+  (backup-service-type
+   (backup-configuration
+    (host "123.123.123.123")
+    (port "8888")
+    (method rsync+vpn)
+    (folders
+     '(("/path/folder1" "/target/destination1")
+       ("/path/folder1" "/target/destination2")))))
+#+end_src
+
+# TODO: More examples?
+
+* A flood of packages and services
+
+Nix has some 40,000+ packages.
+
+Guix is getting there: 12,000 as of FOSDEM 2020.
+
+#+begin_notes
+Services don't have well known names.
+
+How do we find our way around this mess?
+
+More general problem: search programs / services is hard.
+#+end_notes
+
+* GNU Guix and GNU Shepherd
+
+- Can be installed everywhere.
+- Shepherd services drag Guix dependent packages automatically.
+
+* Problem 1: File search
+
+SQLite databases from substitute servers.
+
+* Problem 2: Package parameters
+
+# TODO: Really talk about this?
+"Gentoo USE flags"
+
+Example: FFmpeg compiled with AAC encoding
+
+* Problem 3: User interface
+
+- Command line of course...
+- ...But also GUI!
+
+# TODO: Videos?  Demo with Helm?
+
+#+begin_notes
+Live, fuzzy search that "does what you mean."
+Understands if you are looking for a service, file, application.
+#+end_notes
+
+* The Art of Searching
+
+- À-la "web search-engine".
+- Databases: Wikidata
+- Smart search engines: Xapian?
+
+#+begin_notes
+Wikidata is a good way to factor the work between distributions.
+#+end_notes
+
+* Community contributions
+
+# Mention Alternative To?
+
+- Recommendations
+- Number of downloads
+- Ratings
+- Tags?
+
+#+begin_notes
+We don't want to include tags in a permanent databases:
+- Too subjective.
+- Evolves over time depending on the latest trends.
