If so, what's the name of the stack, and how can I get that stack? If not, how does the Ruby code work without returning something?

Any ideas for a better way? def secureImage(request,imagePath): response = HttpResponse(mimetype="image/png") img = Image.open(imagePath) img.save(response,'png') return response (Image is imported from PIL.)

• Challenging yourself as a programmer?

I enjoyed going from CF to PHP, but I feel like I am getting a bit stale. I have been looking at different things like Ruby, Python, Obj C (iPhone). The problem is, there just isn't enough time in the day. What would be a fun new thing to learn that would refresh me a bit and challenge myself to learn more?

  - by flaxeater

  I have committed to learning C now, I'm good with Python/PHP/Bash but I've decided I'm limited by not being fluent in C. However I cannot imagine working in a language without lists and hashes, maybe I'm just jumping a gun, but surely there are 'standard' collection libraries. I do not see any in the GNU standard lib though, any suggestions?
