Last weekend I was in New York for the Northeast Scala Symposium and the Foursquare Hackathon, so I took the opportunity finish up the query part while I had their developers around to answer questions.

Loading BoingBoing into MongoDB with Scala

I want to play around with Rogue by the Foursquare folks, but first I needed a decent sized collections of items in a MongoDB. I recalled that BoingBoing had just released all their posts in a single file, so I downloaded that and put together a little Scala to convert from XML to JSON. The built-in XML support in Scala and the excellent lift-json DSL turned the whole thing into no work at all:

Traffic Analysis In Perl and Scala

I needed to implement the algorithm in Practical Traffic Analysis Extending and Resisting Statistical Disclosure in a hurry, so I turned to my old friend Perl. Later, when time permitted I re-did it in my new favorite language, Scala. Here's a quick look at how a few different pieces of the implementation differed in the two languages -- and really how idiomatic Perl and idiomatic Scala can look pretty similar when one gets past syntax.
