Starting next month Ruby5 will be looking for new co-hosts to do one Ruby5 Episode a week. Nick and Jim have done a fantastic job for the past few months, but they've decided to focus more of their time on their new video show Doctype.
Here's more information about the job.
If you and a friend are interested in auditioning for Ruby5, here's how to do it:
Send us some Audio - We'll need to hear that you can record quality audio. Script up a talk through a single Ruby story. It shouldn't be any longer then a minute and should cover a new tool that we haven't covered yet on the podcast. If we dig it then we might even play it on the podcast. Be wary of cheesy humor or co-host lines which say "What is that?". We're looking for intelligent conversation in a short amount of time (which is why we script in the first place). No, you don't have to script if you really don't want to.. but it's hard to talk about tech topics in a short amount of time without being VERY concise.
