# I use nateware/redis-objects as an easy way to implement atomic counters in my ActiveRecord models in Rails.
# But I still need counters in sql to sort models with them.

# So the CounterSyncWorker goes through the object space, selects all class that is an AR model and includes Redis::Objects,
# check for all columns that have _sql equivalents, fetches the value in redis and store into the AR attribute.

# Example:

# when uploading a photo that belongs to first user:

Hi all,

I recently attended a local tech meetup where they talked about the deficiencies of javascript and the prominence of this new coffeescript language and how it improves developer productivity. For example, instead of stitching strings together in an old and ugly way:

str = "<a href=\""+url+"\">"+text+"</a>"

you can write in a rubyique way:

str = "<a href=\"#{url}\">#{text}</a>"
