What the Zope Transaction Manager Means To Me (and you)
If you use Python and you use SQL databases, you probably use SQLAlchemy. It's an ORM, it's a SQL DSL, it's extremely powerful and flexible. If you use a web app framework, you generally want to tie the lifecycle of your database transactions into the lifecycle of your HTTP request handling. Different web frameworks offer different approaches for this; if you use the Pyramid web framework, you hav

7 tips to Time Python scripts and control Memory & CPU usage
When running a complex Python program that takes quite a long time to execute, you might want to improve its execution time. But how? First of all, you need the tools to detect the bottlenecks of your code, i.e. which parts take longer to execute. This way, you can concentrate in speeding these parts first. And also, you should also control the memory and CPU usage, as it can point you towards new
Combining Traversal and URL Dispatch — The Pyramid Web Framework v1.5.1
Combining Traversal and URL Dispatch¶ When you write most Pyramid applications, you'll be using one or the other of two available resource location subsystems: traversal or URL dispatch. However, to solve a limited set of problems, it's useful to use both traversal and URL dispatch together within the same application. Pyramid makes this possible via hybrid applications.

I experimented with it until I understood it and then added it to the list. This post is part of that list, after some cleaning up. If y
