One of the programming lessons I find myself re-learning again and again is this: It's turtles all the way down. When I first started my current job, just after graduation, I was working in a frontend development rôle. The app I was working on involved storing customer data in a proprietary database system, and from time to time, I'd get stuck.
I've just got a new laptop, and wanted to avoid messing around with symbolic links in order to install PIL in a virtual environment. I've just discovered patch, and thought I should automate my process of installing PIL (a process which previously involved me making a trivial edit to the setup.py file).
A new version of Django was released a couple of days ago. I'm currently at 11 sites using Django, so upgrading them all manually (which I did last time) is a pain. To help me out, I wrote a tiny Fabric script to spin through my sites, check if they're using the version of Django that was upgraded, and if they are, upgrade them.
I do a lot of development without an internet connection[1. Mostly on the train to and from work.], so being able to install packages into a virtual environment without a connection to PyPI is pretty useful.
I tried out Fabric a while ago, but never really got anywhere with it. Time passed, and I forgot it existed, and wrote my simple scripts for automating deployment of my various sites, using Paramiko. It was incredibly tedious, but meant I could deploy my sites from whatever computer I was on, provided I had a checkout of my code. Then I re-discovered Fabric, and realised I was about to throw away a lot of code.
Upcoming releases of Django will remove django.contrib.markup, but I still want to use it. I looked around for alternatives (perhaps a third party app?), before deciding to roll my own.
A good friend of mine alters cards for Magic: The Gathering for fun and profit. Previously, he posted them on his Twitter feed, along with a brief description, but that doesn't provide a great way of seeing at a glance the sort of things he does - a place to point people who ask for examples of his work.
My web-development office is a fast-moving place. It averages around 50 miles per hour, and I work on a laptop normally squished between two people on the train to and from the office. When I happen to have a spare moment to build websites at home, I tend to use my desktop, which is running Ubuntu. I do my editing in emacs, where I've gradually got things set up more or less as I like them.
Order(n) is a pretty bad idea. Originally, my SearchIndexes for Haystack looked a bit like this: Then, when someone ran a search, and I wanted to display a result, I'd load up a template (which template I loaded depended on grabbing the model name, as recommended in the docs), and any attributes of the model I wanted to display required doing a database lookup to fetch the data, like this: This has a fairly obvious problem - each time you display a search result, you do a database [Read more...]
A long while ago, I discovered that running Django tests is much faster if you use SQLite, and if you turn off South (this now seems pretty obvious, but at the time was a bit of a revelation to me).
