Building storm-0.9.0-rc2 on Mac OS X w/ Oracle-jdk1.7.0_07 11/04

Instructions for building storm locally

I'm running netty, so jzmq + 0mq are not guaranteed to work.

Install zeromq-3.2.4 with homebrew

brew install zeromq

Install nathanmarz-jzmq

remote debugging java processes
Let’s assume you’ve got an executable JAR file which launches a server listening on port 4444.
server:~ mchung$ java -jar server.jar
or
server:~ mchung$ java -classpath server.jar com.mchung.Server
Launching a Java process with debugging activated is easy when you pass in the correct arguments:
-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000
For example:

A funny little hack I put together over the weekend. Read this for more information: http://ping.marcchung.com
/**
* Each record captured by the form is represented as a PingAlert.
*/
function PingAlert(rowId, record) {
this.rowNum = rowId + 1;
// See Spreadsheet for information on index.
this.url = record[1];
this.email = record[2];
// Extra columns
