Python Design Patterns
Alex Martelli
Design Patterns must be studied in the context on
the language in which they'll get implemented --
the Gang of Four made that point strongly in their
book, though almost everybody else seems not to
have noticed. This talk explores some "classic"
DPs in all the various categories -- Creational,
Structural, and Behavioral -- studying how they
show up in Python programs and how they interact
with Python's special strengths.
Speaker Bio:Alex Martelli is Uber Tech Lead
(Production Systems) at Google. Alex is the author
of "Python in a Nutshell", co-editor of the
"Python Cookbook", a Member of the Python Software
Foundation, and winner of the 2002 Activators'
Choice Award and 2006 Frank Willison award for
outstanding contributions to the Python community.

| Automated Testing Patterns and Smells |
 |
Google Tech Talks
March, 6 2008
ABSTRACT
The extensive use of automated testing has been a
breakthrough practice in improving the quality of
software produced by developers. By now, many
companies have experimented with the use of
automated functional tests and unit tests. Those
that have had good experiences with it rave about
it and cannot imagine having been successful
without their automated tests. But for every
success story there are many (often untold)
stories of disappointment. What separates the
success stories from these disappointments?
In this presentation Gerard describes a number of
common problems encountered when writing and
running automated unit and functional tests. He
characterizes the problems in the form of "test
smells", describes their root causes, and suggests
possible solutions expressed in the form of
patterns. Although these patterns and smells
originated from the developer community's use of
xUnit for automated unit testing, many of these
smells and patterns are equally applicable to
automated functional/acceptance tests using tools
such as Watir and some even apply to Recorded Test
tools such as Mercury's QuickTest. While many of
the practices he describes are directly actionable
by developers or testers, many also require action
from a supportive manager and/or system architect
to be achievable.

lives at the intersection of technology and art --
a place that can get very complicated. Here, he
talks about paring down to basics, and how he
creates clean, elegant art, websites and web
tools. In his book Laws of Simplicity, he offers
10 rules and 3 keys for simple living and working
-- but in this talk, he boils it down to one
simply delightful way to be.

System Of A Down
Song: Patterns
Album: Storaged Melodies (Unofficial CD)
Lyrics:
Life is a story,
Go ahead and find your sight.
Life is your glory,
Go ahead and live the night.
But to live means to be here,
In the present, now,
Do you try to bow for the gift of your day,
Then you cede to the morning sun.
Pretending that we live doesn't make us alive.
Life is a story,
Go ahead and find your sight.
But to live means to be here,
In the present, now,
Do you try to bow for the gift of your day,
Then you cede to the morning sun.
Pretending that we see doesn't give us the sight
Pretending that we live doesn't make us alive.
What is it that makes us lose sight,
True sight, of what is real and essential?
I'll take organised patterns of chaos
Over the chaotic organisations of man, any day.
Pretending that we see doesn't give us the sight
Pretending that we live doesn't make us alive.
Pretending that we see doesn't give us the sight
Pretending that we live doesn't make us alive.
The patterns in the carpet do add up though,
You don't have to count.
The patterns in the carpet do add up though,
You don't have to count.

Leveraging Web 2.0 Design Patterns For Enhanced
Accessibility
T. V. Raman (Google)
HTML DOM+ JavaScript constitutes the assembly
language of Web Applications. Access To Rich
Internet Applications --- ARIA --- adds in a
couple of additional op-codes for helping Web
applications better communicate with adaptive
technologies such as screenreaders. How do we now
push the envelope with respect
to Web applications and adaptive technologies such
as screenreaders and self-voicing browsers in a
manner similar to what we as Web developers have
collectively achieved for the mainstream user?
This session will demonstrate programming
techniques that help Web developers experiment
with and build in the latest accessibility
techniques into their Web applications. We will
base this session on project Google-AxsJAX.
Developers should know JavaScript, but session
doesn't require deep AJAX hackery.
