On the Interwebs, number 5
Some websites I have found interesting (in no particular order):
Loading Scripts Without Blocking — Goes through all the options for including your external javascript files. I had no idea there were so many options!
Piston — This looks like exactly what I was missing from Django.
The First Rule for Software Development — When I am programming quickly, this is the first thing I ignore. Probably shouldn’t.
Rack Middleware for API Throttling — This looks like a perfect use for Rack.
SelectorGadget — This thing is awesome.
PHP Quick Profiler — I haven’t used this, but this looks awesome.
Facebook Will Become a Relying Party — I’ll believe it when I see it.
