Great talk!
I enjoyed this - I felt personally validated because I've struggled with NetBeans trying to make it play nice with Xdebug and it was good to hear that it's a difficult process.
My colleague installed Xdebug last night during the Hackathon and by using profiling was able to cut the loading time of our homepage by 80%. Thanks so much!
This is a very rich talk with a lot of potential.
Give a definition of Fraud up front, and the different types of fraud you're attempting to mitigate during your talk. Right now this is in the middle of your talk. Move all the fraud types to the front, then the progress through that list and show how to mitigate each one. This will give the audience a roadmap for what you're going to talk about, and if they're not familiar with the problem domain, it can help bring them in.
The click fraud stuff is awesome, and you could probably do a talk on that alone, but it's very dense with code and math. The code itself is hard to follow as you're talking about it. Some of this was due to code formatting and variable naming, but I understand you're trying to condense it to fit on the slide. This might be better abstracted across several slides as simple math equations, instead of code, and displayed in the same order as your code uses.
Some of my feedback may be due to my own unfamiliarity with the problem domain, so keep that in mind too :)
Great delivery!
Easily the best presentation of the conference. Clear, thorough, and useful; good pacing and diagrams. Absolutely excellent.
Very interesting talk on a topic not usually covered, i really enjoyed the linearity in teaching the different solutions, so going from the simplest and showing the downfalls and advantages and then progressing to other solutions, very well delivered.
Great presentation!
Very well prepared and Derick obviously knows the subject matter inside out.
This has to be my favorite session at Tek11 - live code demos, well organized slides, great presentation skills, and Derick kept the audience engaged throughout the presentation.
Loved the talk and how it made me have to think about a new way to do things. David always forces me to consider new concepts, technologies & mythologies for large scale systems.
Excellent job and fantastic content. I won't repeat what the other said about delivery, but I did want to state that I was highly impressed with the information and depth of research you did. I would have loved a "roadmap/checklist" at the end to help summarize all your findings.
David managed to fit a ton of information into a short period of time, and he did an excellent job summarizing the developer's rationale for decisions made as well as how those decisions can aid in rapid api generation.
