Oh yes, that stuff... (In case anyone cares)

I know no-one really cares about how the internal project is going, but I did finally manage to get the front-page tree control to display the (now recorded) summary data. So far only one piece of it, but the data is now getting in there, so it's just a matter for tweaking what's stored and ...
wxPython is migrating rather fast (Looks like maintenance on the wx projects would be a good idea)
Written by

Just reading through the wxPython migration guide and change-log. I need to get cracking and update wxoo for the new apis & the changes. There's a lot of stuff that looks like it may break some of the hackier bits. Also thinking that I should see about creating and donating a multi-method mechanism to provide ...
The next bug awaits... (Hierarchy properly created, but no record of group's values)
Written by

Some day real soon I'll be able to make the front-page tree control display the group data... sigh. For some reason the group-data recorder refuses to actually insert any data (though it will insert empty records). I'm suspecting a problem in the database definition (i.e. lack of a unique key) as the code all seems ...
Software bugs are most similar to ticks (They suck the blood (time) right out of a project)

Been trying to track down this silly bug for... far too long. Basically two fields from the scanner aren't getting copied to the tracking table, as a result, the automatic generation of network hierarchy is failing (it can only assert that the modems belong to the CMTS, not that they exist on a particular channel). ...
Shrubbery and such-like (Tree controls developing apace)

Vindaloo.
Webui uses a modified, chaining-friendly version of Zope3's page templates. It's very easy to create recursive templates, as the templates can readily call any registered view for any object to which they have access. The tree control is such a recursive template. It does a little work up-front to see how many children the current ...
Growing trees... (Webui gets new controls today)

Client wants the UI to have an overview page, so looks like I'll be creating a tree+grid control to display all of the branches of the system with summaries of their current status. Doesn't look too terribly hard, so I'm expecting it to be a royal PITA :) .
Yesterday was useful, but the last ...
Metaclass presentation & code online (Well, presentation was always there, but the code is just up now)
Written by

I've just uploaded the final metaclass presentation and the code samples for it to my website. The code samples are very low-level and readily followed (I hope), they just show where you put your finger to accomplish the various effects discussed in the presentation. The presentation is the full 74 page PDF I presented ...
Getting the machine back up to speed (Post-conference blahs setting in...)
Written by

Compressing focus back to the work I need to get done today is proving hard. Too many ideas and possibilities still orbiting around in my head. There seems to have been a surprisingly small amount of discussion of the conference online, or I'm just looking in the wrong places. Oh well, suppose I'll just fire ...
PyCon wrap-up (Jiggety-jig)
Written by

Well, that was a long 5 days of basically non-stop talking (in other words, I loved it). The metaclass presentation seemed to go fairly well, though I'm told that my rather self-deprecating presentation style distracted at least one audience member. Most feedback seemed to be of the "that clarified it for me" vein.
Togl rises from the grave yet again (I should really stop fixing the darn thing)

Well, spent most of the evening on PyOpenGL and TTFQuery, with some cleanup work in OpenGLContext as well. New release of TTFQuery that works around a bug in FontTools. PyOpenGL 2.1.0 is getting closer, with the major change being compilation tweaks to try to tell the user what's wrong when the configuration doesn't work, ...
