From: Timothy Goddard Date: 2005-11-19T17:52:22+09:00 Subject: Re: Best OS for Ruby Dev/Best OS for Ruby Hosting Ruby is, I believe, primarily designed for use with Linux, although the code is highly portable. Since Linux is the primary development platform, it may also have the fastest bug fixing and the most thorough testing. As a result, your best bet for hosting would be a server-grade Linux OS such as RHEL, CentOS, or the server versions of other distributions. For development, consistency with your hosting platform may or may not be a concern. You can probably use anything here, but if your rails app relies on some more advanced libraries you may be best off with linux again, as package management makes that side of things much simpler and you can ensure that both are running exactly the same libraries. Other similar unices such as BSDs are also likely to work well. Mac OS X would OK as well.
