A goofy, async, incomplete implementation of unless
/**
* user-space unless, some syntactic sugar from ruby implemented in JS
* @var {bool} statement - any statement in JS that evaulates to a boolean. Watch for truthiness here.
* @var {function} callback - adds the shiny sheen of async programming to this.
*/

Some common commands I still haven't committed to muscle memory
// Note: more here: http://www.mongodb.org/display/DOCS/dbshell+Reference
// also, scripting note: db = db.getSisterDB( "users" ) is a script equiv of use users in the shell
// get rs status
rs.status()
// re-configure replicaset
config = rs.conf()
//manipulate the config data here
rs.reconfigure(config);

Created February 25, 2011 21:10
From boxed ice, how to get the last oplog date.
/* Choosing the right MongoDB oplog size can be difficult, especially if your usage is growing. So here’s quick way to see what the last item in the oplog is. If your down slave or backup is older that this, it won’t be able to resync: */
use local
new Date(db.oplog.rs.find().sort({$natural:1}).limit(1).next()["ts"]["t"])
