Present Your 360° Panorama Images With JavaScript
More and more often you can see a cool 360° panorama. Today, I will play with two libraries that present images as 360° panorama views. I will test two libraries, first is Panorama Viewer by Pete R. which is the simplest I could find, and Three.js which is most complex one I could find. Both are free and easy to start with.

How to write an MVC-framework in Ruby
What if we wrote a web application similar to a typical rails-application? I.e. it will have MVC, routing, migrations, some configs, all in all, everything like it’s supposed to be.

manpages - man pages for ruby
I love man pages. And I am a bit disappointed that most command line tools written in ruby don’t offer one. Maybe it’s because of the poor support of rubygems for it. To help fix this, I developed the manpages gem. It scans for man pages in your gem during the installation phase and links them to a folder that the man command can find. Please give it a try.

Cheers.
