Installing PloneRSS

Notes for the less persistent.

One of Plone's marked faults has been the lack of an out-of-the-box RSS aggregation product. Although there have been a number of attempts (CMFSin, CMFNewsFeed, CMFFeed), these are unfinished, quirky or only semi-functional. Fortunately, PloneRSS is a robust solution for gathering and publishing newsfeeds on your site. Unfortunately, installation ...

Encoding types in etree

Setting encoding in the header of ElementTree generated XML.

Not that I'm picking on ElementTree or anything but ...

Normally XML documents will declare their character encoding in their opening tag. And, normally, this will be utf8. (This may be a standard.) So this is a common sight:

xml version='1.0' encoding='utf8'?>

An oddity in ElementTree is ...

Installing Pydee on OSX

Short notes on getting Pydee (and PyQt) to run on a Mac.

Pydee is new and nifty graphical frontend for using Ipython.

Version control systems for Mac OS X

Some quick notes from my search for decent source code control.

This document was originally written in late 2003 / early 2004. The scene has changed some in the meanwhile, with various offshoots of Arch and Subversion gaining a lot of mindshare, and some of the URLs are probably now invalid. However, the broad conclusions still hold, and this is left here ...

VisualWidget, don't do It

More accurately, can't do it. A schema for Archetypes Visual Widget that works.

Archetypes Visual widget - the WYSIWYG HTML editor that shows up on Pages in Plone 2.5 - is pretty damn nice. I've had problems with Epoz and this is the first embedded web editor that makes me think about giving up on restructured text.

Getting it to work in your ...

Installing and using PIL

Overcoming the sometimes tricky installation of the Python Imaging Library and improving image quality.

While some people have reporting installing PIL on MacOSX without problems, there are legion reports that say otherwise. Frequently this revolve around PIL installing without JPEG support. There are a myriad of solutions (involving editing make files, configure flags, using fink to install dependencies, using package managers, casting goat entrails ...


A new, and poorly explained, feature of Python classes.

Around version 2.2, Python rejigged its classes with some useful extensions. Unfortunately these enhancements have been explained so poorly that they appear in little published code.

One such enhancement is __slots__. An attribute of this name in a class restricts what attributes can be created in objects of that ...
