So you want to write a framework? Accidental lessons from

I've got fingerprints elsewhere.
This isn't about Python.
This isn't about web frameworks.
Best of Breed vs Batteries Included
"Batteries Included" Frameworks "Everything comes in the box" One package
to download/install Minimal dependencies No decisions to make Documentation on the parts
"Best of Breed" Frameworks Pick from existing selection of libraries
Glue logic to tie them together Many dependencies Multiple decisions may be required Documentation on integration
None
Hybrids are possible.
Why pick one over the other?
History matters.
It's hard to be best of breed when the breed
doesn't exist yet.
Ian Bicking and SQLObject http://bit.ly/bicking-goodbye
Picking "best of breed" early can be detrimental.
History matters.
Backwards compatibility
Time is relative.
“ A rule of thumb that has worked for me
is that if I'm excited to play around with something it probably doesn't belong in production ” Maciej Ceglowski (Pinboard)
Backwards compatibility has a price.
Batteries Included can still be backwards incompatible.
Best of breed encourages you to pick and choose.
Is a choice of batteries really what is required?
"Batteries included" doesn't mean "Can't use other batteries".
Messaging matters.
Timing matters.
The 90% framework.
Out of the box experience matters.

Implicit documentation
Models and Forms class MyUser(models.Model): name = models.CharField(max_length=100) age =
models.IntegerField() date_of_birth = models.DateField() class MyForm(forms.Form): name = forms.CharField(max_length=100) age = forms.IntegerField() date_of_birth = forms.DateField()
Tools vs ecosystems
Jacob's Tractor
Tools vs ecosystems
Metcalfe's Law: The utility of a network increases with the
square of it's participants.
Ecosystems
Microframeworks
Remember to share with the other children.
Sending the wrong signals.
Packaging systems matter.
Community matters.
Outreach is important.
Absent friends

Requiem in pace
“ A society grows great when old men plant trees
whose shade they know they shall never sit in. ” Greek proverb
Kid, you can move mountains. (98 and ¾ percent guaranteed)
He's not the messiah....
