"In the Java world there was always a problem with dependencies. All the jars we had to mange by hand – quite awful. Thankfully there is a Maven project which helps us in requirements management. But what about Python? Is there any way to handle necessary libraries? Of course, there is! It is a tandem of virtualenv and pip." by Marcin Swierczynski

"Last week I’ve completed an interesting task within our project: building internal link-shortening system based on persisted objects, not on constant URLs. The main requirement was to get as loosely-coupled design as possible. In the perfect world the “shortenable” classes should know absolutely nothing about link-shortening mechanism. How to get such a flexibility in Django? I’ve used the ContentTypes framework with generic relations and it works pretty well!" by Marcin Swierczynski

How to isolate customer's data from one another (one database per customer).

"The pthreads API is inherently simple. Not in the sense that it makes multi-threaded (MT) programming a breeze (I doubt this is possible), but in the sense that it provides everything that’s needed to write MT programs, and only that. In other words, pthreads solves a single problem, and solves it well." by Eli Bendersky.

"The Django ORM is pretty complicated and it takes too much time for contributors to understand all the necessary details. In order to make the process as easy as possible we've implemented a backend template which provides a simple starting point for a new backend based on our simplified API. It also contains sample code, so you can better understand what each function does." by All buttons pressed

"Python is the greatest thing to happen to computer science since the Turing Machine! Well, no, but it has inspired me into a personal renaissance for software writing. Its flexibility, widespread community support, and leveraging of legacy C and Fortran code also make it an outstanding language for social science researchers." via Zero Intelligence Agents.

Since I was a Python guy before I ever started using Ruby, the transition has mostly been an easy one, but there are some fairly significant differences in design and philosophy between the two frameworks that are worth thinking about if you’re picking a platform for a new project."

Paul Graham wrote on his blog "you could get smarter programmers to work on a Python project than you could to work on a Java project. I didn't mean by this that Java programmers are dumb. I meant that Python programmers are smart. It's a lot of work to learn a new programming language. And people don't learn Python because it will get them a job; they learn it because they genuinely like to program and aren't satisfied with the languages they already know."
