Advanced Configuration in Firefox 3

Everyone can customize a lot of options in Firefox through the "Tools>Options" or "Edit>Preferences" menus. Well the other way is to make customizations through the advanced configuration interface by typing "about:config" in the address bar.

Downloading Rails Casts

Rails casts is hosting Ruby on Rails video tutorials. It explains a lot of tips for development and how different rails components work. I highly recommend it for rails starters. I wanted to download all the previous episodes, that needed me to open the page of each episode, find the link for the mov file, and click save as. So i created a bash script to visit the links of the episodes and do the job automatically #!/bin/bash for ((i=$1;i<=$2;i+=1)); do wget$i -O- | grep -oi '[a-z_0-9]*.mov' >> links done while read LINE ; do wget "$LINE" ; done < links Now the script can be used to download any range of episodes. below i'm calling it to download episodes from the episode #1 to episode #115 ./ 1 115

Heads Up With Radiant CMS

Radiant is an open source RubyOnRails based Content Management System, designed for relatively small websites. One of the nice things about radiant is that it the templates themselves are stored in the database like ordinary content, making all interactions with the site once it is deployed through the administration interface. In radiant, a page can be composed of several named parts. Parts of the interface that is shared among several layouts (like navigation bar, footer, header) can be stored in snippents . Using snippets, layouts and page parts helps the site creators to elegantly build and maintain their website. Some features that is beyond a CMS, like having a page that sends emails or a form that stores data somewhere, can be obtained through radiant extensions . let's start a new radiant project: first you need to install the radiant gem gem install radiant --include-dependencies then create a new radiant project specifying the database engine used. radiant --database m
