My site is smarter than I am
Looking through my stats today, I found an incoming link from a blog written entirely in Chinese. Now, I don’t read Chinese (I know about half a dozen words of Mandarin, but couldn’t begin to pronounce them with the right tones), so I ran it through Babelfish and found that this person was — apparently — commenting on how “comforting” my site was to him.
Django tips: get the most out of generic views
Recently at work I had the chance to revisit an application I’d written fairly early on in my tenure at World Online; I was still getting used to doing real Django development and to some of the quirks of our development environment, and ended up writing a lot more code than I needed to, so I was happy to be able to take a couple days and rewrite large chunks of the application to be more efficient and flexible.
The biggest win was more careful use of generic views, which this ...
So it seems that something’s broken somewhere in all the hacks I do to the comment system, because every attempt to submit a comment is now met with
AkismetError: missing required argument.
I’m working on it.
Update: commenting still won’t work, but apparently I’m not the only person running into this bug. I can’t find any notes regarding changes to the Akismet API, but that feels like the most obvious reason why this is suddenly happening.
Updated again: and just like that, things are working again. Judging from a couple other people ...
Programming tips: learn optimization strategies
Recently I spent a little time talking about the tradeoffs between “concise” code and readable code in Python. Throughout that entry, I was using as an example a simple function which calculates numbers in the Fibonacci sequence; here’s one variation:
def fib(n): if n < 2: return n return fib(n-1) + fib(n-2)
The Fibonacci sequence is a classic example from introductory programming materials, because it teaches recursion, and recursion is an important core concept for productive programming. But it can also be useful for another educational topic ...
Django tips: auto-populated fields
One of these days I’m going to run out of frequently-asked Django questions to answer. But today isn’t that day, so let’s look at one of the most common questions people ask: how do you set up a model with one or more fields that never show up in add/edit forms, and get automatically populated with some specific value?
A simple example
Let’s say you’re writing a to-do list application, and you want to have fields on the list model to store the date it was created and the time it ...
