Great, clear presentation with good examples.
The problem statement was interesting: given a large list of urls, figure out which ones are from "bad" sites and which are from "good" ones. I wish he had spent less time talking about where the problem came from and more time explaining the basics of machine learning.
Well-delivered, great slides, interesting topic. Could have been less repetition with showing the code changes and then showing the screencast making those changes. Also, would have been nice to talk a hair slower :-), but the energy was great!
I enjoyed Jordi's presentation style even though it rambled a bit. Really interesting to hear about the real-world issues he faced. And the part about how to manage an open-source project was insightful.
Interesting; fun presentation!
Tons of great information, great presentation. Speak more slowly!
Very clear presentation, great answers to questions. Thanks for explaining your methodology!
A lot of fluff at the beginning, but then got interesting with details about performance of various php versions.
Great talk, well planned and presented, interesting topics!
Off-topic given the conference's leaning towards open source. I didn't find it interesting or relevant.
