I've been doing a lot of work in Clojurescript [https://github.com/littleredcomputer/sicmutils] lately, and the time finally came to pull in my first vanilla Javascript dependency [https://github.com/infusion/Complex.js/]. The default way to do this seems to be the CLJSJS project [http://cljsjs. »
Cascalog + Hadoop Counters, Finally!
I've just merged a Cascalog pull request of mine [https://github.com/nathanmarz/cascalog/pull/270] that gives Cascalog operations access to the statistics that Cascading generates at the end of each job. I've also added global inc! and inc-by! functions that let you increment custom »

Cascalog Testing 2.0
A few months ago I announced Midje-Cascalog [http://sritchie.github.com/2011/09/30/testing-cascalog-with-midje.html], my layer of Midje testing macros over the Cascalog MapReduce DSL.

Testing Cascalog with Midje
I've been working on a Cascalog testing suite these past few weeks, an extension to Brian Marick's Midje [https://github.com/marick/Midje], that eases much of the pain of testing MapReduce workflows. I think a lot of the dull work we see in the Hadoop »
