The video of Microsoft’s Bing Maps augmented reality demo at the TED conference last week shows how they integrate Flickr imagery, indoor panoramas, Worldwide Telescope and even live videos to allow a really impressive time travel for certain places.

“We see this space, three-dimensional environment as being a canvas on which all sorts of applications can play out,” said Bing Maps’ Blaise Aguera y Arcas.

This little plugin provides you with a protected area for your users on your mephisto blog. Its built to use engines compatible mephisto available in the mephisto version 8.2.

To install this plugin, run:

script/generate plugin_migration
rake db:migrate RAILS_ENV=production

This will make some changes to your production database and will expose a new Userlogin tab to your Mephisto administration interface. From there you can create new userlogins. When creating new userlogins provide a username and a password (Attention! This is designed for ease of use and easy remebering. The passwords are NOT ENCRYPTED! Don’t use this for really important stuff) along with some sites you like to provide inside of the protected area.

You need to create a liquid template for every site you list as protected. So, if you list “family_gallery” as a protected site, you need to create a template called “family_gallery.liquid”. This page will be available at http://yoursite.com/protected/family_galery. The page http://yoursite.com/protected will show a login form (if not logged in) or the conten of “protected_index.liquid” (otherwise).

Ambiguity madness

Coding in hastiness combined with a limited vocabulary late at night will certainly result in comprehension difficulties at the very next morning:

<%= "#{t("role.role")}" %>: <%= "#{t("role."+role.role)}" %>

Kids, don’t try this at home.

This is a very informative slideshare on inference and the power of the Semantic Web. To emphasize the potential of the Semantic Web, Myungjin Lee used RDF and OWL constructs to represent the statements of his slides. Very impressive, though.
