Unable to configure handler 'console': __init__() got an unexpected keyword argument 'strm'

Django and upgraded from 2.6 to Python 2.7

Hopefuly this quick post will save someone time, I recently upgraded our Debian servers from stable (squeeze) to testing (wheezy).

Unfortunately this resulted in an odd error:

Traceback (most recent call last):
  File "manage.py", line 12, in 
    execute_from_command_line(sys.argv)
  File "/srv/www/django/development.FOO.com/virtualenv/src/github-django-django-stable/django/core/management/__init__.py", line 453, in execute_from_command_line

The solution is relatively simple but not easily foundable in Google or Bing. The logging definition in settings.py needs to be updated to use the new Python 2.7 'stream' keyword argument instead of 'strm'. My updated default project logging settings below:

LOGGING = {
 'version': 1,
 'disable_existing_loggers': True,
 'filters': {
        'require_debug_false': {
            '()': 'django.utils.log.RequireDebugFalse'
        }
    },
 'formatters': {
  'verbose': {
   'format': '%(levelname)s %(name)s %(asctime)s %(module)s %(process)d %(thread)d %(pathname)s@%(lineno)s: %(message)s'
  },
  'simple': {
   'format': '%(levelname)s %(name)s %(filename)s@%(lineno)s: %(message)s'
  },
 },
  # let the 'handlers' get all messages and filter level in 'loggers'
 'handlers': {
  'null': {
   #'level':'DEBUG',
   'class':'django.utils.log.NullHandler',
  },
  'console':{
   #'level':'WARNING',
   'class':'logging.StreamHandler',
   'formatter': 'simple',
   'stream': sys.stderr,
   # 'stream': sys.stdout
   # see https://code.google.com/p/modwsgi/wiki/ApplicationIssues#Writing_To_Standard_Output
   
  },
  'mail_admins': {
   #'level': 'ERROR',
   'filters': ['require_debug_false'],
   'class': 'django.utils.log.AdminEmailHandler',
   'formatter': 'verbose'
  }
 },
 'loggers': {
  # catch all logger ex. any logger = logging.getLogger(__name__)
  '': { 
   'handlers': ['mail_admins', 'console'],
   'level': 'WARNING',
  },
 }
}

How to child proof a fireplace

DIY - Do it yourself fireplace child guard Our wonderful 8.5 month old Sofia has become a crawling race car with an untamed thirst for exploration. And so with the cold nights approaching we needed to child proof the fireplace. This however proved to be more difficult than would reasonably expect, I've checked the local Toys "R" Us, Walmart, and even a Canadian Tire with no success for a ready to use product. Internet search was more fruitful and returned a few online stores one could order from, however in all honestly they didn't look too sturdy to me. So I build my own relatively quickly and inexpensively. Materials needed is a privacy plastic lattice - the smallest hole pattern - a few screws and anchors; tools needed are a drill, and a handsaw if you don't have the lattice cut at the store - that’s it. The construction consits of screwing the lattice into the wall and the final product is easiest explained through following pictures. Feel free to +1 this po…
