Delayed Vagrant Up

If after a halt and up vagrant appears to stall at this step...

==> docker: Waiting for HGFS kernel module to load...

run vmware setup and except all defaults and this should saolve the issue.

Process Substitution Error in IRB

simple example of process substitution in shell (bash)

> echo <(true)
/dev/fd/11

now with Ruby (IRB) - note: Ruby is shelling out to /bin/sh not /bin/bash

Prune Resque Workers

There is an issue related to running Resque on Heroku and Resque's ability to clean it's state information for workers. This is mostly a cosmetic issue however we got to a point where the Resque Dashboard would timeout because it was trying to display hundreds of workers it thought were sitll running.

This is a heavy handed approach to cleaning up. We are finding any worker that was stared longer than a day ago and manually calling the unregister method. Be advised this will throw DirtyExit errors.

# **** grab a reference to the redis instance ****
redis = RuoteKit.dashboard.storage.redis;nil

# **** delete all errors ****
redis.del(redis.keys('*errors*'))

# **** delete all expressions and workitems from march 2013 ****
redis.del(redis.keys('expressions*201303*'))
redis.del(redis.keys('workitems*201303*'))
