Holy Paginator, Batman!

Django has a really great pagination framework built in, but it does encourage you to write code like:

entries = MtEntry.objects.filter( entry_status__exact = 2).order_by( '-entry_created_on' )
paginator = ObjectPaginator(entries, 5)
page = int( request.GET.get('page', 1) )
object_list = paginator.get_page(page - 1)
c = RequestContext(request, {
'%s_list' % template_object_name: object_list,
'is_paginated': paginator.pages > 1,
'results_per_page': paginate_by,
'has_next': paginator.has_next_page(page - 1),
'has_previous': paginator.has_previous_page(page - 1),
'page': page,
'next': page + 1,
'previous': page - 1,
'last_on_page': paginator.last_on_page(page - 1),
'first_on_page': paginator.first_on_page(page - 1),
'pages': paginator.pages,
'hits' : paginator.hits,
})

Amazon On My Tivo

Tivo has finally found a partner to distribute content via broadband to their series 2 and 3 boxes -- Amazon.com. So AppleTV has a competitor. Who's going to be first to let me get Ze Frank in my living room? Or build youtube channels?

One Laptop Per Child

I got to play around with one of the first production OLPC machines today. It is incredible. As you can tell from this shot I took during its first boot, it runs linux. But once it is up it has a really cool gui and a fast hibernate-awaken facility that makes full reboots relatively uncommon.

They have been rewriting as much of the software stack as they can in python. Why? Because they want to make it easy for children to edit the software. Their commitment to open source is ...
