sendgrowl is a simple Bash script for Mac OS X which redirects sendmail to Growl. Messages piped to the sendmail binary are displayed as Growl notifications instead and - when clicked - the entire message is opened in a Quick Look preview window. Quite useful for Cron output and - to some degree - for developing Rails apps which send mails.

Locomotive is probably the best CMS for Ruby powered websites and webapps already. However, one essential feature for use in multilingual areas or contexts is still missing: content i18n. Here's an opportunity to change this. (If you prefer not to create an account on the Locomotive forum, just comment here instead.)

The right-rails (RightJS for Rails) plugin has seen some major updates recently, time for some brainwash from the author of RightJS.

If you like RightJS, consider voting for RightJS to be included in Google AJAX Libs API. And if you don't know this both powerful and lightweight lib yet, you might want to check it out, nomen est omen!

The few Obj-C code lines of autotest-fsevent allegedly misbehave on Mac OS X 10.6. Can anyone with a Snow Leopard SDK help out?

Autotest is great, but it's filesystem polling tortures your CPU, HD and battery. But fear not, there's a solution for those on Mac OS X 10.5: The autotest-mac gem features support for the FSEvent core service, Growl and some eye candy.

Here's an updated autotest howto for rubyists on Mac. It contains a few improvements such as a simple workaround to make Growl notification reliable on Leopard, nice colored rubystone images for Growl, catching the "cannot run tests" (e.g. due to syntax error) case and clearing the terminal on each run while maintaining the ability to scroll back.

Looking for an cheap excuse why not to switch from PHP to Ruby? You might find it here.

I've just updated my cheat sheet on regular expressions now featuring more details on Ruby, C and Obj-C as well as some previously ignored PCRE specialties. Looks best if you have a color printer :-)

With stable Ruby 1.9.1 out, it's time to get it installed on your computer. One way, particularly useful for those working on Macs, is Gentoo Prefix. This article helps you to get started.
