Simple datastore batch writes in Google AppEngine

Google AppEngine has just came out of "Preview" today,  & changed the pricing model & quotas accordingly. A major change in the pricing model is that instead of charging for the total CPU time of DB operations, they are now charged by the number of DB operations. This means that instead of tunning the DB operations themselves, a much better approach will be to just batch them together (when possible).

 

The Pull Task Queue API of AppEngine is very useful for batching DB operations, which can be written to the queue & pulled reliably in batches for execution.

Django workhop videos

 In the last conference of the Israeli Internet Association, there was a day-long Django workshop by one of its founders - Jacob Kaplan-Moss. It was intended for people new to Python & Django & I highly recommend it for anyone wishing to start learning Django.

 

Here's the full video of the workshop (slides are also available under each video).

 

 

Enjoy.

Confucius Task Manager

Introduction

Confucius Task Manager or simple Conficius. The idea is standing behind was to create an interactive, annoying, really annoying tool which is able to manage your life daily TODO list, makes sure you are making  progress in your current task, reminds you about your uncompleted work, and again makes sure and reminds you and, finally, rates you progress at end of the day.

 

How it works

A nice article on Drupal vs. Django

 A nice & detailed article comparing the Drupal CMS & the Django framework:

http://birdhouse.org/blog/2009/11/11/drupal-or-django/

 

It provides a nice overview of the 2. The authors conclude that:

Study compares productivity levels of Python+Django vs. C#+ASP.NET

 A recent study measured the productivity of using Python+Django vs. C#+ASP.NET, in terms of user-stories per week. The results are that 1 Django developer is equivalent to 2 ASP.NET developers, productivity-wise:

The Django team that participated in the benchmark, BTW, had no prior experience with Django, which probably implies that the difference can be even higher.
