It's time to thank those great companies and individuals who help keep Ruby Inside (and often other Ruby sites) going.

Linode - Xen Virtual Servers

Linode is a well-established provider of virtual private server hosting - some five years now. They're very competitive and have recently redesigned their site. Their entry level package is $19.95 and gives you 360MB of RAM, 12GB of storage, and 200GB bandwidth. I personally pay (no freebies!) for my own Linode to play around with and it costs $39.95 a month for 720MB of RAM and 24GB of space, which works really well with Phusion Passenger for running Rails apps (and Sinatra apps, for that matter). A blog post Slicehost vs Linode compares them to Slicehost - they stand up well!

New Relic - Rails Performance Monitoring Systems

New Relic provides high-end performance monitoring solutions for Rails applications and they include 37signals and Shopify amongst their customers (very high praise indeed!)

Back in November, New Relic also secured $6m of new funding.
