在 gradle 內，執行特定 task 時，需要不同的設定時，可以透 taskGraph 來判斷。下面這例子，很典型地是在 publish 新的 library 時，不含設定檔：

gradle.taskGraph.whenReady { graph ->
    if (graph.hasTask(uploadArchives)) {
        jar {
            exclude '**/*.properties'
        }
 }

MongoDB provides a Javascript shell. But Javascript is no fun without underscore.js 

Turned out its straight forward to use underscore.js while scripting mongodb.

Here are the steps.

1) Use underscore to write your db script file (say my_commands.js)

       E.g: _.each(db.dbname.find().toArray(), function(itm) { ... })

Unsafe Node Assassinate

On Cassandra 1.1.x, nodetool removetoken on a dead node hangs. The only way to reliably remove the node from the cluster is to use an undocumented JMX command to force the remove of the node from gossip.

Upgrading to 1.2.x and above should obviate these steps in favor of nodetool removenode - See 1.2 Docs

It's probably also a good idea to run a nodetool repair after this operation - See wiki
