Day 2 time! Here are some highlights:

Guido van Rossum

Guido gave an awesome keynote! Folks, switch to Python 3! Women, become a core Python dev!

Gabriella Coleman

Gabriella followed up with a really interesting talk on her anthropological studies of Anonymous and free software organizations.

Disney gift

Disney gave out little 3D printed microbots as gifts to the speakers. So neat!

Jessica McKellar

I saw Jessica! She and Ned were the first ones to tell me about PyCon about two years ago. They were also the first ones to encourage me to submit a proposal. I’m really glad I met them ’cause I’m a PyCon speaker now!

Later in the night, after a fish n’ chips dinner with the Warby folks, Harry, Albert, and I walked through an underground mall, when we were surprised with a light and water show. Here’s the last scene of that show.

Since I got a few questions after my talk, I thought I’ll summarize them here. If I’ve missed a question, feel free to ping me.

Q: How to smooth a model in Blender?
A: Use subdivision surfaces modifier. Note: the more subdivisions you have, the more vertexes/edges/faces it creates, which might lead to slower performance.

Q: How to create SVGs to import into Blender?
A: You can use Inkscape, another open source software, to trace your picture into a vector image.

Q: What are some resources for 3D scanning objects?
A: 123D Catch is a good starter tool by Autodesk. There’s also lots of open source alternatives.

Q: What are some other resources to learn Blender?
A: CGCookie has really nice Blender tutorials.

Q: Can you talk more about what you did for mesh repair?
A: Here’s a blog post I wrote a while ago about mesh repair. I submitted my mesh repair script as a patched for Blender’s 3D Print Utility Add-On. Check it out here.

Q: Can you control the fill of the model, when 3D printed, through Blender?
A: If you’re printing the model yourself, you usually control the fill downstream of creating the model. For example, take a look at the different fills for Slic3r. If you’re sending off your model to be printed by a service, they’re usually filled solid.

Hopefully this is helpful to folks.

My morning was spent in bed recovering from yesterday’s madness.

My work buddies have arrived in Montreal. They brought along a Kareem plushie to model in touristy photos.

In the afternoon, following my personal PyCon tradition, I helped packed swag bags. If you grab a swag bag tomorrow, there’s probably 1/5 chance I helped pack it!


Later in the evening I ran into Ned, who gave me an honorary Boston Python sticker! I feel so honored!

Check out his talk on Saturday: Facts and Myths about Python names and values

Now it’s nearing midnight, and Michelle and I are chillin’ in our hotel room, sprucing up our presentations last minute.

Check out her talk tomorrow: Grids, Streets and Pipelines: Building a linguistic street map with scikit-learn

It’s right before mine: 3D Print Anything with the Blender API

So excited for tomorrow!

It’s PyCon time!

Yesterday I woke up at 4:30am to catch a flight to PyCon.


Note to future self: definitely fly out the night before!

That afternoon, I gave a tutorial on Intro to 3D graphics with Blender and the Blender API.

graphics :D

We modeled and textured a house!

All of the course materials are on my GitHub.

Highlight of the day was when I put a speaker ribbon on my badge. I felt super legit!


Looking forward to all the talks tomorrow!

Today Harry and I played with an antique German steam engine. It’s a toy that’s been in his family for a couple generations.

While some of the components were missing, the steam engine still worked wonderfully!

The top metal tank holds water, which is heated by the furnace below. The generated steam will travel through a metal pipe to the piston, which will then turn the wheel.
