clojure-mode-like syntax highlighting for the SLIME REPL (here, via @nipra) -- It works pretty well, except that it doesn't handle the prompt yet.
want 2 learn some clojure? >git clone git://github.com/relevance/labrepl.git >cd labrepl >mvn clojure:repl browse to http://localhost:8080/ (via @WarN4N) -- And this is how twitter became a repository for user manuals. If you were wondering how to use @stuarthalloway's Labrepl, here is the manual.
Why using Maven for Clojure builds is a no-brainer (bonus screencast with a pinch of snark) (here, via @cemerick) -- This is one stance in the debate of Lein vs. Maven or build vs. re-use that has been going on for a while in the Clojure community. Chas provides some arguments in favor of re-use, in this case reusing maven and adds in a very compelling screencast. Worth the 10 minutes.
Clojure + Apache Tika (here, via @alextott_en) -- Tika is a MIME type detection and extraction library. Clj-tika is just a clojure wrapper for it.
#clojure client library for Apache #cassandra (here, via @8quashes) -- Not the first library for Cassandra in clojure. There is also clojure-cassandra
Added a new repository to github, a css-sprite generator written in Clojure (here, via @jharwig) -- Grabs your images directory, creates a sprite with all of them and also spits out the CSS code to access each image individually. You are interested in it if you are developing high-traffic highly-interactive websites and your pages to load very fast.
Dynamic data tables with #Incanter (here, via @liebke) -- How to use sliders to manipulate datasets dynamically.
