So I watched a slideshow where an author (name intentionally omitted) had a snippet that iterated over a list. That’s all well and good, but one thing that bugged me was that it checked for the length of the array first, and then iterated.
list_len = len(mylist)
if list_len > 0:
for item in list_len:
…
This just feels wrong [...]

Malcom Tredinnick gave an awesome presentation about the Django ORM.
The code for the ORM is located in django/db with juicy bits in the following locations:
django/db/models/query.py (public queryset API)
django/db/models/sql/* (Public API->SQL conversion. Deep dark internals. Does’t know DB, knows SQL)
django/db/backends/* (Individual DB wrappers, third-party wrappers possible. This is where you actually talk to the DB). See [...]

The Django foundation has pushed out the second alpha release of Django 1.0 , see the blog post here
Earlier in the week I received “Practical Django Projects” in the mail — chomping at the bit for enough time to get into it.
Exciting times.
I wonder if there isn’t some room in the Django ORM back-end [...]

Languages that do not have native boolean data-types that let you branch on non-boolean data types evaluate all non zero values as “truthy”, (-1) evaluates to true. You might be wondering, as I did, why that is? After poking around and looking at some x86 assembly instructions, I suspect it is a compiler optimization.
At [...]

It will be hosted the weekend of September 6th and 7th at the GooglePlex (Mountain View, CA). Since this is the first conference (and hosted at Google) space will be limited to 200 attendees so I suggested putting the Django [...]

I’ve been super busy lately barely finding the time for the mediocre updates I have posted. My team-mates and I have been working on a revamp of a major advertising platform and it’s a lot of work.

The next release of Hadoop (0.18) will likely have Java6 has a requirement, thus forcing the Hbase project to adpot the same requirement. The current Hbase release is 0.12, and this will probably only affect 0.3, so it’s a ways off — just be ready.
Here is the HBase Jira issue: https://issues.apache.org/jira/browse/HBASE-636

I’m really about to geek out on you — I’m going to (complain) compare the Google App Engine configuration file (app.yaml) to the Django setting.py.
Simon Wilson of OpenID and django-openid fame wrote a post on logging in Django and got me thinking a long these lines.
App.yaml sucks. Why? Because it’s not really “pythonic” and [...]

The Django team has knocked off one of the milestones for the 1.0 release — Changeset 7477 merges the queryset refactoring effort into django-trunk.
The goal of the queryset-refactor branch was to add a layer of special sauce to the Django ORM and make it easier (possible?) to (among other things) have model inheritance.
Here is a [...]
