TWiD Week Ending 12/23/07

[empty]

Rob and I have been emailing back and forth about how we can
collaborate. We have several ideas for different things but we're
going to think them over and then make some decisions in the new
year. For the time being we're going to both post our updates to this
list on Sunday just so we can maybe exchange some things. Here's my
list. It's possible that it may change slightly because sometimes I
make modifications as I'm recording depending on program length, etc..

Thanks

Because of a broken work week and lots of holiday stuff I didn't
maintain a list this week. There were some interesting threads on
django-devs this week:

newforms-admin and django.contrib.auth:
http://groups.google.com/group/django-developers/browse_thread/thread/7da58968b4456c76
Talking about what it would take to remove admin's dependencies
(contrib.auth, Log, and Messages).

Cache Invalidation Proposal -- CachedModel
http://groups.google.com/group/django-developers/browse_thread/thread/9e9050624b3975c6
Lots of interesting stuff if you're interested, like how do you go
about invalidating objects in a cache if they are in the cache many
times.

Odd MySQL bug
http://groups.google.com/group/django-developers/browse_thread/thread/d4180b8addf5e970/70e9f33ee095769d
More funny than anything as Malcolm discovers the weird depths of
MySQL while working on the queryset-refactor branch.

I'd include these in a blog roundup:

http://blog.michaeltrier.com/2007/12/21/retrieving-selective-fields-with-django
Nice example of trouble shooting with the ORM

(ok, you got the rest of 'em)

My Trac Summary can't be listed b/c the code to generate it is on my
computer at work and apparently the wake on LAN activity thing isn't
set up. Hmmm.

Thanks for sharing Michael.

Yeah it's been kind of messed up with holidays.

Good stuff in the Google Groups--I'm very hit and miss with following
those, so this is a big help for me. I have already recorded for this
week, but I have a feeling next week is going to be light, so I might
touch on a few of these. Especially the cache one. I also will be
touching on the collaboration that we're doing and reference your work
on your blog. I just had way too much this week, coming in at 25+
minutes.

Thanks Rob.

Have great holidays.
