Tagulous v0.12 is now available - it adds support for Django 1.10 and addresses several issues - see the changelog for full details.
Note that this version may require additional upgrade steps - see the upgrade notes for more information.
I've released a new version of Mara, my network service framework written in Python. It aims to make it easy to build TCP/IP services, such as echo servers, flash policy servers, chatrooms, talkers and MUDs.
It's event-based; that is to say you write event listener functions which you bind to events that your service raises - like Connect, Receive or Disconnect.
Mara is on pypi, so you can pip install mara, then start writing your service. An echo server in Mara looks like this:
from mara import Service
service = Service()
@service.listen(mara.events.Receive)

class Person(models.Model):
name = models.CharField(max_length=255)
skills = TagField()
person = Person.objects.create(name='Bob', skills='run ...Today I'm releasing TinyWFL, my tiny web font loader which is about 95% smaller than other popular loaders.
When web fonts started to gain adoption around 2010, the problem people had was FOUT - the flash of unstyled text while you waited for the browser to download the font. I think most people would agree that this has since been solved very comprehensively by webfontloader from Google and Typekit, and that it's now the de-facto standard loader - but back in 2010 or 2011 FOUT was still an issue, which is why I wrote my own.
To be accurate, my ...
