Ruby

pg_search builds ActiveRecord named scopes that take advantage of PostgreSQL’s full text search

Notify.allowed_email_domains

Splits "gitlab.corp.company.com" up into "gitlab.corp.company.com",
"corp.company.com" and "company.com".
Respects set tld length so "company.co.uk" won't match "somethingelse.uk"
