TurboGears Doc Sprint

Spent almost the whole day today on the TurboGears 2.x documentation sprint.  I wound up just wading in and focusing on bringing a single document "up to spec" as it were.  I have an itch to sit down and try to restructure the whole hive of documents.

Along the way had to learn the ...

Finally setting up the Asterisk server

Today just never seemed to materialize.  I wound up sleeping most of the afternoon to try to finish off the last of this cold.  I spent the evening assembling furniture and then watching a forgettable movie with Soni.  In the middle of that I've been working on getting our Asterisk server set up.  I ...

TurboGears "offline" processes (crons, command-line commands, etc)

TurboGears uses the Paste commands system to create command-line entry points that, for example, set up your database or start your server.  When you get to larger projects, however, you will often have other things you need to do "in the context of your application" from the command line, such as periodic imports of data ...

Wrapping JQuery plugins for ToscaWidgets/TurboGears

Continuing my explorations of JQuery + TurboGears today, I started working on a simple RTE-light wrapper widget.  RTE-light is an extremely small, simple analogue to TinyMCE, so I figured it would be easy to set it up with the tw.tinymce project as reference.

There's a paster script to auto-start a widget project, so that ...

ToscaWidgets JQuery and Flot Plotting (Tutorialish-ly)

Continuing on from our previous tutorial, here's a quick example showing how to create a Flot plotting library plot using tw.jquery's FlotWidget class.  In our root.py controller module, we'll import the widget and some support functions:

from tw.jquery import FlotWidget
from math import sin,cos
import simplejson

The FlotWidget ...

ToscaWidgets JQuery and TinyMCE (Tutorialish-ly)

So you've browsed the ToscaWidgets web-site and know that there's a JQuery Plugin and a TinyMCE (Rich-text-editor control) plugin... now how the heck do you use them?  Not a lot of documentation for these two pieces, so I've tried to cobble together a minimal example.  Fair warning, I'm piecing this together ...

I forget how advanced TurboGears 2.0 is, sometimes

I wanted to code up a single-form application for updating/editing the PyGTA events.  Since it runs on Vex and I didn't want to bother them with setting up per-user WSGIs or TurboGears for me (they do give me the space free, after all), I went with bald CGI.

Wow.

I've written very ...

First PyGTA Class Begins to Take Shape

We had a lively PyGTA this evening on the topic of concurrency.  After which I put out a call for those who are interested in helping setup and teach (low-cost) courses on Python.

Our first course looks to be an Introduction to Django, likely on a Saturday in early November, taught by a consultant who ...

Hard-linking and disk-space... whatever...

Toying yet more with compressing rdiff-backup repositories with hard-linking.  Turns out there's already someone who's done it.  My script for hard-link finding is different than the (packaged) one he's using, but it seems to have the same basic idea (I use filecmp, though, rather than reading the files myself, and I don ...

Hack to map Vertex Buffer Objects into Numpy arrays...

This post from the numpy list shows you how to turn a ctypes c_void_p into a numpy array.  The glMapBuffer() function maps your currently-bound array into a void * which you can access directly... combining the two:

def map_buffer( vbo, access=GL_READ_WRITE ):
    """Map the given buffer into a numpy array..."""
    func = ctypes.pythonapi.PyBuffer_FromMemory
    func.restype ...
