How To Install Ruby on Rails Ubuntu Server 11.10

Ruby Rails is a Web application framework created in 2004 intended as a rapid development web framework. It was intended to emphasize Convention over Configuration (CoC) meaning the developer only needs to specify unconventional aspects of the application. For example, if there is a class Sale in the model, the corresponding table in the database is called sales by default. It is only if one deviates from this convention, such as calling the table “products sold”, that the developer needs to write code regarding these names. It has also been designed around the “Don’t repeat yourself” principle. Both of these ways of thinking allow you, with Ruby Rails, to create excellent, dynamic websites very quickly. So to get started we need to setup a Ruby Rails development server on Ubuntu (Ubuntu 11.04, Ubuntu 11.10) Read the rest of this entry »

Backup Gmail on Linux

In this tutorial I am going to discuss how to backup your Gmail emails to your own computer. Now personally I trust Google and keep allot of data on their services, but when it comes to emails I like to be doubly sure. It’s extremely rare but on occasion even Gmail has some problems, for example read this news article about some data loss at Gmail. When I read this I thought, “dam what would I do if I lost my emails“, well that scared the hell out of me, I’m always going back though old emails to find information (password, email addr’s, phone numbers, etc..) and this important information is only stored in my emails. So following the rule that “data only exists if its stored in three places” I thought I would add my own step to Google’s backup solution, just to be safe, and this is how I did it.
