-@Beyond the CRDT silver bullet
+What local-first software asks of a system, and why conflict-free
+replicated data types answer only part of it.

-# 1 - no spinners: your work at your fingertips

-# 5 - the long now

-# 6 - security and privacy by default

-	# in node A
-	s = "Hello, Alice"
-	
-	# in node B
-	s = "Hello, Bob"

-## Software license
-...
-@@"In our opinion, maintaining control and ownership of data does not mean that the software must necessarily be open source."
-
----
-## Example 1 - intentional restriction
-.
-	#!/bin/sh
-	TODAY="$(date +%s)"
-	LICENSE_EXPIRATION="$(date -d 2020-10-27 +%s)"
-	if [ "$TODAY" -ge "$LICENSE_EXPIRATION" ]; then

-	# tomorrow
-	$ ./useful-adder.sh

-## Example 2 - unintentional restriction

-	# tomorrow, with more data

-# local-first *requires* free software 
-
-Otherwise "The Long Now" (ideal nº5) is lost
-

-## Denial of existing solutions
-..
-@@"In principle it is possible to collaborate without a repository service, e.g. by sending patch files by email, but the majority of Git users rely on GitHub." 
-.
-Solution: either GitHub+CRDTs or git send-email 
-
----
-## Plain-text formats
-.
-@@"Git is highly optimized for code and similar line-based text file"
-.
-It even pulls software to the plain text directtion, e.g.:
-- delivery-templates
-- common-core.protocols.config
-.
-Why not exploit that more?
-
----
-## Ditching of web applications
-..
-@@"The architecture of web apps remains fundamentally server-centric
-.
-% FIXME: links
-Disagree.  Contrast PouchDB with Android Instant Apps
-
----
-## Costs are underrated
-.
-- storage
-- backups
-- maintenance
-.
-Example: blog vs vlog
-
----
-## Real-time collaboration a bit overrated
-.
-It is only possible on the presence of reliable, medium-quality network connection
-..
-@@"X also works when inside an elevator, subway or plane!"
-
----
-## On CRDTs and developer experience
-.
-@@"For an app developer, how does the use of a CRDT-based data layer compare to existing storage layers like a SQL database, a filesystem, or CoreData?  Is a distributed system harder to write software for?
-.
-@YES.

-% FIXME: link
-See "A Note on Distributed Computing"
-
----
-## Conclusion
-.
-Why this is a "paper I love": it took offline-first and ran with it.
-.
-But a pinch of CRDT won't make the world local-first. 
-.
-The tricky part is the end of the sentence: "in spite of the Cloud".
