This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
Daniel also maintains neko, a project that aids in the development of Android apps using Clojure. A key piece of it is an extension to the Android SDK's toolchain to make building the Clojure bits of your app automatic using the standard workflows provided by that toolchain (Ant, adb, and so on).
Daniel's latest talk on using Clojure on Android can be seen here.
