User Story Mapping - Book Notes

Summary of the book User Story Mapping by Jeff Patton

Front Matter

• Story mapping provides the big picture that a pile of stories often misses.
• Stories are meant to spark conversations and shared understanding
• If you want to create effective software to support an activity, then you need to look to those build the software as a vital source of ideas for its capabilities, because it’s programmers who know best what software can do. Programmers need to understand what their users are trying to achieve and should collaborate in building the stories that capture those user’s needs.
• Its entirely reasonable that programmers build software one feature at a time. However if this same approach is taken to design the behavior and scope of a program then a monster is produced.
• Shared docs are not shared understanding
• Good documents are like vacation photos

# There is no UI to delete deployments from a GitHub repo. 
# They are annoying and confusing to have stick around if you are not actually using them.
# So here is a script to delete them ALL.
# USE AT YOUR OWN RISK!!!

# N.B. this script uses jq which is not standard so you must install it. It is awesome. 
# https://stedolan.github.io/jq/

If a Docker build fails it can be a PITA to figure out what is going on. This can help.

In the build output, look for the last layer that was used before the failure. The line will look something like this:

---> Running in fec66b09f2e8

Copy that identifer.

Then run (replacing the id with whatever yours is) the name of the image can be anything I used temp so if I forget to delete it, it will be obvious later that it is indeed o to delete it:

# must use postgres11 not 12 as Timescale does not yet support 12 and brew defaults to 12
brew install postgresql@11
brew install timescaledb

# remove postgres 12 to avoid headaches and confusion - it is installed by timescale as a dependency :headdesk:
brew uninstall --ignore-dependencies  postgresql

brew services start postgresql@11

# Python script to find the largest files in a git repository.
# The general method is based on the script in this blog post:
# http://stubbisms.wordpress.com/2009/07/10/git-script-to-show-largest-pack-objects-and-trim-your-waist-line/
#
# The above script worked for me, but was very slow on my 11GB repository. This version has a bunch
# of changes to speed things up to a more reasonable time. It takes less than a minute on repos with 250K objects.
