User activation codes without additional database tables or fields
UserAuthCode generates an authentication code for Django user objects. This code can be used to verify the user's email address and to activate his account. Unlike other solutions there's no need add any tables or fields to your database. Current version is hosted on [GitHub](https://github.com/badzong/django-userauthcode). There's also an example how to use it in your Django project.

HTTPS redirections middleware with updated URL template tag
This middleware redirects HTTP requests to HTTPS for some specified URLs, in the same way as [85](http://djangosnippets.org/snippets/85/). It also changes the `url` template tag to use the `https` scheme for the same URLs. For example, if you have the following URL pattern: url(r'^accounts/login/$', 'django.contrib.auth.views.login', {'https': True}) then the template: {% from future import url %} {% url 'django.contrib.auth.views.login' %} will render: https://host.example.com/accounts/login/ and any plain HTTP requests to /accounts/login get redirected to HTTPS. URL patterns not marked with `'https': True` remain unaffected. Notes: * The HttpRequest object must be present in the template context as `request`, so add `django.core.context_processors.request` to `TEMPLATE_CONTEXT_PROCESSORS` and make sure to use `RequestContext`. * This snippet overrides the existing `url` template tag. Remove the last line and register the new `url` function properly, as a separate tag, if this makes you unhappy. You'd then have to change your templates to use it. * It would be nicer to change the way reverse look-ups behave instead of changing only the `url` template tag, but the URL resolver, and the `reverse` function, know nothing about requests, so have no way to find the correct host name.

Amazon S3 browser-based upload form(FIXED)
This is a 'fixed' version of snippet [1868](http://djangosnippets.org/snippets/1868/) Changes: *Correctly handle the Content-Type, because amazon requieres it to be named with a dash and we can't use dashes in the form attributes declaration. *Also added max_size handling, with the corresponding update to the policy generation. *Added an example usage with some javascript for basic validation.

Function decorator for caching function results in local memory
@cache(60) def heavy_computation(): for x in xrange(10000000): pass # just waste some time` The result of `heavy_computation` calls will be cached for 60 seconds. This cache decorator does not use the Django cache backend and uses the local memory instead.

Filter to add zero-width space to break up long words
If you have long words (no spaces) that are so long that it's messing up your design, add a 0-width space in the word every X chars. Usage: Step 1. Inside your app's directory, create dir called 'templatetags'. In that directory, create a .py file (say 'app_extras.py'). Make sure you make this a python module, make an empty the init .py (with the 2 underscores on each side). Step 2. Inside template (make sure app is on INSTALLED_APPS list in settings.py): {% load app_extras %} Step 3. Enjoy! {{ some_long_word_with_no_breaks|zerowidthspace_separator:25 }}
