This article takes you into the world of scientific programming -- from simple numerical computations to some complex mathematical models and simulations. It explores various computational tools but the focus remains scientific programming with Python.
This post describes in more detail how you can become productive using pymongo.
One of the key features of TurboGears2 is the great CRUD extension. Mastering the CRUD extension can really make the difference between spending hours or just a few minutes on writing a web app prototype or even a full application.
In this talk, Russel Winder co-author of 'Python for Rookies' takes an interactive wander through Python as a high performance language.
This post describes, in great details, how SendHub moved their Django app to Heroku.
ZeroMQ is an intelligent messaging framework and described as "sockets on steroids". PyZMQ adds even more convenience to them, which makes it a really a good choice if you want to implement a distributed application. This article talks a bit about how you could generally design your application to be flexible, maintainable and testable.
The QGIS Python console is great for doing one-off tasks or experimenting with the API. Sometimes you might want to automate a task using a script, and do it without writing a full blown plugin. Currently QGIS does not have a way to load an arbitrary Python script and run it1. Until it does, this post illustrates a way you can create a script and run it from the console.
There are a number of ways Evolutionary Algorithm can be parallelized. One of the easiest things to do is to run parallel instances of the algorithm with different initial random seeds. This post show how to use Pyevolve + PiCloud to run Pyevolve's Genetic Algorithm implementation with 10 different initial seeds on PiCloud - all running in parallel.
This post shows how to create a web2py app using modules datamodels instead of models.
This episode is an interview with Martin von Loewis.
This is a Python programming tutorial for the PostgreSQL database. It covers the basics of PostgreSQL programming with the Python language.
This video is a panel discussion with these three luminaries from Django, PyPy, and the Python world.
Interesting Projects, Tools and Libraries
Airy is a new Web application development framework. Contrast to most currently available frameworks, Airy doesn't use the standard notion of HTTP requests and pages. Instead, it makes use of WebSockets (via Socket.io) and provides a set of tools to let you focus on the interface, not content delivery.
