Phew, tiring trip to PyCon this year. This was my second year after hitting up my first last year. The conference definitely felt larger than last year as they crossed 2,200 attendees. It’s unbelievable to see how large the Python community has gotten. I can’t stress what great job the people that put this together.

Last year I hardly knew anyone. This year, however, I got to put faces to people I’ve interacted with over the last year, welcome back those I met last year, and get some face to face time with new co-workers from Canonical. The social aspect was a larger chunk of my time this year for sure.

Side note, I listen to The Changelog podcast from time to time, and I love their question on who you’d love to pair up/hack with as a programming hero type question. I got to meet and greet mine at this PyCon by meeting up with Mike Bayer. He’s behind some great tools like SqlAlchemy and Mako. What I love is that, not only does he rock the code part, but the community part as well. I’m always amazed to see the time he puts into his responses to questions and support avenues. Highlight of my PyCon for sure.

I’ll post a seperate blog post on my sprint notes. I feel that if you’re going to go, you might as well stay for sprints. I get as much out of that as the conference parts itself. I think I made some good progress on things for Bookie this year. The big thing is that an invite system is in place, so if you’d like an account on Bmark.us let me know and I’ll toss an invite your way.

Notes

  • Introduction to Metaclasses
    • Basic but reminded me how the bits worked and had some good examples. I like this because I often write ‘the code I want to be writing’ and then write my modules/etc to fit and metaclasses help with this sometimes.
  • Fast Test, Slow Test
    • Just a reminder that fast tests are true unit tests and run during dev which helps make things easier/faster as you go vs the whole ‘mad code’ then wait for feedback on how wrong you are.
  • Practical Machine Learning in Python
    • mloss.org – check out for lots of notes/etc on ML in OSS
    • ml-class.org – teach me some ML please
    • sluggerml – app he built as a ML demo
    • scikit-learn : lots of potential, very active right now
  • Introduction to PDB
    • whoa…where have you been all my life ‘until’ command?
    • use ‘where’ more to move up stack vs adding more debug lines
  • Flexing SQLAlchemy’s Relational Power
  • Hand Coded Applications with SQLAlchemy
    • <3"><3 SqlAchemy. Some really good examples of writing less code by automating the biolerplate with conventions.
  • Web Server Bottlenecks And Performance Tuning
    • lesson: if you think it’s apache’s fault think again. You’re probably doing it wrong.
  • Advanced Celery
    • check out cyme https://github.com/celery/cyme, possible way to more easily run/distribute celery work?
    • cool to see implementations of map/reduce using celery
    • chords and groups are good, check them out more
  • Building A Python-Based Search Engine
    • Good talk for into into terms and such for fulltext search
  • Lighting talks of note
    • py3 porting docs: http://docs.python.org/howto/pyporting
    • bpython rewind feature is full of win over ipython
    • ‘new virtualenv’ trying to get into stdlib for py3.3, cool!
    • asyncdynamo cool example of async boto requests for high performance working with AWS api (uses tornado)
    • I WANT the concurrent.features library…but it’s Python 3 :(

For the first year and a half in Canonical I worked with the amazing Launchpad team, with the ambitious goal of building a new user interface, introducing AJAX in an established code base and rolling it all out on time. While all of that was overwhelming in itself, what was more important to me was making sure the UI remained consistent across time.
Long story short, it was a success and it's been 8 months since I've left the team and the established process is still on-going.

I wrote a paper on the whole experience and presented it at the agile conference XP2010 in Norway.

Here's the introduction:

When I started working with the Launchpad team I was tasked with designing and rolling out a new interface using cutting-edge technology on a well established product and team. The existing processes and team structure made it very hard to roll out big changes while also ensuring consistency as time went by.
While the general designs and work ow changes were being eshed out, I started to drive some change to the existing processes, enabling me to be successful at an objective that would take a year to accomplish, and unexpectedly, beyond that.
The project was 4 years old and had over 500 dynamic pages with different templates and layouts that had been left untouched at different points in time. The goal for the next year was to make the application easier to use, even enjoyable. I also had to make the UI consistent across the board, take the project from static HTML pages into the wonderful world of in-line editing, streamlined work-flows and predictable interactions. In parallel, fundamental features that had been developed were going completely unused and we needed to turn that around. A re-usable AJAX infrastructure had to be developed from the ground up, new features needed to be designed and delivered, and general navigation issues needed to be addressed.
However, this story isn't about the success of the roll out of a new interface, but rather the success in the process changes that evolved during that year and how the project went from nobody feeling ownership over the user interface, to the developers taking strong ownership.

I feel very passionate about this subject, and hope this experience can help other projects and teams.
