Q:
Should I use Pylons or Pyramid?
I was planning to move from Django to Pylons, but then I bumped into Pyramid.
What are the differences between Pylons and Pyramid?
I read some text in PylonsBook, which currently covers Pylons 0.9.7, and wonder if it is a to start for Pylons and Pyramid.

"Pylons isn't being \"cancelled\", and it will continue to receive updates. That said, the \"future\" per se is in Pyramid. On the mailing list is has been referred to as Pylons 2.0.

How does Python handle memory?
I've been looking at a in-memory database -- and it got me thinking, how does Python handle IO that's not tied to a connection (and even data that is); for example, hashes, sets, etc.; is this a config somewhere, or is it dynamically managed based on resources; are there "easy" ways ... | How does Python handle memory? | I've been looking at a in-memory database -- and it got me thinking, how does Python handle IO that's not tied to a connection (and even data that is); for example, hashes, sets, etc.; is this a config somewhere, or is it dynamically managed based on resources; are there "easy" ways to view the effect resources are hav... | [
"Python allocates all memory that the application asks for. There is not much room for policy. The only issue is when to release memory.

"This awfully looks like you are using __constant memory. The solution is to use __global memory instead, but you have to be careful about how you access it for best performance.\n__constant memory is a special address space for often used constant values, but is restricted in size on current GPUs.\n"
