I’m almost always enjoying the lessons learned-style presentations from Twitter’s people. The slides below, by Jimmy Lin and Dmitriy Ryaboy, have been used at HadoopSummit. Besides the technical and practical details, there are two things that I really like:

DJ Patil: “It’s impossible to overstress this: 80% of the work in any data project is in cleaning the data”

and then the reality check:

1. Your boss says something vague
2. You think very hard on how to move the needle
3. Where’s the data?
4. What’s in this dataset?
5. What’s all the f#$#$ crap in the data?
6. Clean the data
7. Run some off-the-shelf data mining algorithm
8. …
9. Productionize, act on the insight
10. Rinse, repeat

Enjoy!
