Ringside Notes

Here are some pages of notes that I've taken as I learn the Ringside codebase. I'll eventually move this to appropriate places on the public wiki, but until I find a home for these notes, they will stay here.

• Ringside Demos
• Incoming Outgoing Communication Points
• Undocumented Code
• Ringside Plugin Prototype Flash demo

Some useful information that can be used within Ringside:

• Facebook API - http://wiki.developers.facebook.com/index.php/API
• Some metrics that Facebook collects for apps - http://wiki.developers.facebook.com/index.php/Admin.getDailyMetrics
• Facebook metering - http://wiki.developers.facebook.com/index.php/Admin.getAllocation
• Facebook Java client - http://code.google.com/p/facebook-java-api/

PHP Notes

I'm keeping some notes on PHP.

• Equality
• is_null and isset are always the opposite of each other. Read the comments in http://php.net/is_null - seems like isset is the preferred method to use.
• Article on the PHP file processing functions

SVN Notes

Here's some useful tidbits regarding SVN usage.

• To rollback a particular revision, execute the following (where ### is the revision you want to back out, note the - (dash) prefixing the number - this is required):

  svn merge -c -### <svn http url>

  You can then svn status and svn diff to make sure its all correct. Then svn commit to checkin the changes, which effectively rolls back that revision. Read http://svnbook.red-bean.com/en/1.0/ch04s04.html and http://svnbook.red-bean.com/en/1.0/ch04s03.html for information about merging and branches.

Miscellaneous Notes

• Calculating Running Average

  long newValue = ...;
  long count = currentCountOfItems++; // must be the count of all items currently
  currentAvg = (((count - 1) * currentAvg) + newValue) / count;
