MountainWest RubyConf 2009
Improving the Usability of Your RoR Applications
30:31

The first half is the most interesting, there are several tips how to make UI good looking and how to ensure that user feels safe and comfortable using your application.
One of the examples is gmail's status message after deleting an email - it displays "undo" link in the successful message so the user can easily revert the action after a mistake.
The second part displays changes in a specific application, this part was not much interesting for me.
Good even for non-UI designers, at least the first part.

Nice video, worth of seeing. Usually known facts, but grouped together in an interesting context.

Rails casts
Rails 2.3 extras
9:50 Presents what is new in rails 2.3 (so it not include last features for 2.3.4). It contains explanation how works batches (work db by parts), scope ( set scope of model or query) and try method (safety call of method, really useful method).

Really good video if you don't know described functionality. But it doesn't go deep, so if you know that features then it is waste of time for you.

Ruby code review dialog
42:50 Imaginary dialog with project leader and code ruby expert which shows common mistakes in development. It is focused on two main issues. The first one is breaking of old test during developing new features (breaking fixtures) and automatic deployment server (Hudson). The second one is bad usage of meta-programming and some rules which should be followed to not break working stuff with injection to shared objects.

Really good funny presentation. To reach five stars it missing more details and also way to avoid fixtures is little controversy.
