stop runit_service supervise/ok race condition
Currently we wait 10 seconds for a runit service's supervise/ok named pipe. On slower systems ( cough CentOS 5.x) this 10 second wait is not long enough. This commit updates the embedded runit cookbook that ships in omnibus-chef to match the indefinite block used in the current version of community cookbook:

If you're moving to a different Rails project you have to install new Rubies and bundle - plus you might need to install Redis, Solr or jam your public key on a server somewhere. Even worse, after bundling you notice this is a Rails 2.3 project not a Rails 3.2 and …

These two lessons are interrelated. Tools following the principles in (2) can scale by adding more boxes. And as load increases mature products should have fewer problems. When you do hit problems you'll at least have a community to help fix them. It's when your tools are too tricky and too finicky that you hit walls so high …

…evaluated MySQL vs Solr. I was able to index all the data from the database into Solr and make it queryable from a browser within four days plus some customization on the search algorithm. It would have taken me two to three weeks to do something equivalent with MySQL and it wouldn't be as flexible and customizable as Solr. With Solr, I was able to fine tune search and I still feel there are tons of additional features that will help me address future needs.

Tomorrow, August 22 at 10:00am PDT, I'll present a webinar called Full Text Search Throwdown . This is a no-nonsense performance comparison of solutions for full text indexing for MySQL applications, including:
LIKE predicates and regular expressions
MyISAM FULLTEXT indexes
InnoDB FULLTEXT indexes
Apache Solr
Sphinx Search
Trigraphs
I'll compare the performance for building indexes and querying indexes.
- Smile, Breath and Keep trying: Fulltext search your CouchDB in Ruby
With PostgreSQL there is no need to deploy a standalone full-text search engine like Apache Solr, Sphinx, or ElasticSearch. Right out of the box you can easily discover word matches (even on singular and plural words) and also use different dictionaries. There are several gems that make full-text search on PostgreSQL extremely easy to use and we encourage you to give them a try.
