"...don’t confuse this kind of data exploration, where the goal is to size up the data, with building proper data plumbing, where you want robustness and maintainability. Perl and bash scripts are nice for the former, but can be a nightmare for building data pipelines." Lots of good stuff in this article; this was a highlight.

Hmn. Visualisation of tweets about the word "FIFA" (do the maths there) and all games played of FIFA 10 - so you can see both which teams are doing well, and which countries have good FIFA gamers in them. There's little bits of stats-fluff, but it doesn't go nearly deep enough. It's lovely EA are doing this... but it could be, you know, useful, rather than just shiny? Bungie's statistics crown is still a long way off.

"Someone at work recently asked how he should go about studying machine learning on his own. So I’m putting together a little guide." Ooh, useful. Lots of starting points for machine learning in R.

"Statisticians’ sex appeal has little to do with their lascivious leanings ... and more with the scarcity of their skills. I believe that the folks to whom Hal Varian is referring are not statisticians in the narrow sense, but rather people who possess skills in three key, yet independent areas: statistics, data munging, and data visualization. (In parentheses next to each, I’ve put the salient character trait needed to acquire it)."

"You are a web programmer. You have users. Your users rate stuff on your site. You want to put the highest-rated stuff at the top and lowest-rated at the bottom. You need some sort of "score" to sort by."

"On Tuesday we shipped an update that added a bunch of features / bugfixes / balancing tweaks that came out of the community's feedback. In particular, it made some changes to the underlying TF damage system, and as part of that, it modified the way critical hits are determined. We thought it might be interesting to dig a little into the change, and hopefully give you some insight into our thinking." Another cracking example of explaining game mechanics clearly and directly, to an engaged community.

"We’ve generated what we call the Personal Annual Report for all our users. It’s a unique-to-you PDF of data, visualisations and factoids about your travel in 2008, that we’re delivering over the next week via email to every Dopplr user who travelled in 2008. To give you an example, we thought we’d show you the Personal Annual Report of someone who’s had a very busy 2008 - President Elect Barack Obama." This is super-awesome. Can't wait for mine, no matter how small it is.

"...it’s become apparent to me that social software is a medium turns all communication into a self-representation game whose ultimate goal is popularity."
