Shopify Invests in Research for Ruby at Scale— This is exciting! If you’ve kept an eye on industry comings and goings in recent years, you may have noticed Shopify has brought together quite the team of Ruby and VM experts (whether through direct hires or collaborations) and it’s only continuing – this bodes extremely well for Ruby and reminds me somewhat of when Google went all in on V8..

Soft Deletion with Postgres: Writing the Logic in Postgres Itself— Of course we love writing everything in Ruby, but Postgres, like many database systems, is quite powerful on its own and if you wanted to add ‘soft’ deletion (marking records as hidden rather than deleting them) to your app, you could give the job to Postgres itself by way of rules.
