I need to make a script to read images from a directory, rename them, resize them to a MAX_HEIGHT, MAX_WIDTH, put a watermark logo and save them in JPG.

What is the fastest, one-liner/shortest way to get an Array of "strings/that/are/paths" from an XML file, using Nokogiri preferably. I'd like to build the array with an arbitrary attribute name ('id' in this case), but also knowing how to do it for the element name would be helpful. So this: <root id="top"> <nodeA id="almost_top"...
What are the drawbacks of using the content/data model of a blog like Blogger or Wordpress to store all of your information and then just having it redirect you to your "real" website? I'm wondering if it's a bad idea to setup a blog and just read/write from it but render it in a completely different project, so I don't have to recreate...

I'm in a databases course and the instructor wants us to develop an e-commerce app. She said we can use any framework we like, and now that we're halfway through the semester she decided that Rails does too much and wants me to explicitly write my SQL queries.
