Preface

Hello everyone. With Ceb drama getting so much traction, I decided to do what any rational person would do in this situation - download all public matches of all professional dota 2 players and then scan the all-chat for any racism or naughty naughty words, so the j͇͕͙ͣu͒͆s̼̠͍̖̮̳ͮ̃t̫̙̯͎ͬ̇̊̄iͨć̼͓ͬͨ͑ͣe͉̜̫̱̠̘̋̒ͅ can be upheld once and for all.

There are several nuances that stood in my way.

1. Many professionals' pubs are kept private.
2. Most of the trashtalk happens in ally chat, which isn't saved.
3. Some of the trashtalk happens over mic... which again, isn't saved.
4. Lots of horrible racism happens in non-English, making it hard to look for.

Installing the Oracle Java 8 JDK on SmartOS

1. Go to: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
2. Download the "Solaris x64 XX.X MB jdk-8u66-solaris-x64.tar.gz" tarball from the Oracle Java SE site. You won't be able to paste the URL into curl on your SmartOS instance unless you click it first to get the authentication parameter. Regardless, get the tarball any way that you prefer and copy it onto your SmartOS instance.
3. Extract the tarball and copy it to the location of your choosing.
4. Globally set the value of the environment variable JAVA_HOME to the path of the JVM.
5. Update your PATH to include the Java bin directory by setting it to PATH=$PATH:$JAVA_HOME/bin
