Ruby on Rails – what the f…
Ruby on Rails, often shortened to Rails or RoR, is an open source web application framework for the Ruby programming language. It is intended to be used with an Agile development methodology that is used by web developers for rapid development.

Ruby on Rails is often installed using RubyGems, a package manager, which is included with Ruby. Many Linux distributions also support installation of Rails and its dependencies through their native package management system, anyway no matter the installation technique, installing Ruby on Rails on a Debian or Ubuntu distribution is plain sailing and very easy.

Installing Ruby on Rails using RubyGems

Install Ruby and RubyGems

sudo aptitude install ruby rubygems

As I wrote this post, there was a nasty bug in the Rails dependency notation for Rack, which means you’ll need to install version 1.0.1 of Rack instead of the default version, which is as of now version 1.1.0.

Install Rails

sudo gem install rack --version 1.0.1
sudo gem install rails

That’s all. You are done.

Installing Ruby on Rails using apt-get or aptitude

Install Ruby on Rails

sudo aptitude install rails

That’s all. You are done.

Awareness: Web Application Security

Developing a web applications is often articulated as easy and a good thing for new programmers to start with. Many books and tutorials have been written on the subject, and many frameworks and programming languages have been built to facilitate quick construction of web applications. Just one thing bothers me about this, many of the books and tutorials ignore many of the security issues that are related to building web applications. This fact might explain why we do have such a huge number of insecure and vulnerable web applications around on the net.

Anyway, it is not just bad – a number of initiatives have been formed to communicate the need for security and web-based applications. One of these initiatives is OWASP, which is an open-source application security project. The OWASP community includes corporations, educational organizations, and individuals from around the world. This community works to create freely-available articles, methodologies, documentation, tools, and technologies.

OWASP’s most successful documents include the book-length OWASP Guide and the widely adopted OWASP Top 10 awareness document. The most widely used OWASP tools include their training environment WebGoat, their penetration testing proxy WebScarab, and their OWASP .NET tools. OWASP includes roughly 100 local chapters around the world and thousands of participants on the project mailing lists. OWASP has organized the AppSec series of conferences to further build the application security community.

Hopefully initiatives like OWASP will provide up-coming web developers with a awareness of the security issues related to development of web application and enable them to avoid the classic pitfalls in web application security. At least so far I have learned a lot from OWASP articles and guides.

Linux Job Market Trends: Galloping Forward

September 6, 2007 at 21:34 · Tags: AJAX, apache, Debian, Fedora, Java, Linux, Open Source, Ruby, Ruby on Rails, Ubuntu

According to itmanagement.earthweb.com the numbers, clearly, point to a major industry trend.

Take a look: Dice, the tech jobs site, reports that it had 9,631 Linux job listings in August. While this is a big number, whatâ€™s truly eye-catching is the percentage growth since January: Linux job listing are up a robust 30 percent â€“ three times the increase of overall tech job listings. (Since January, Dice job listings have grown by 10.2 percent, to a total of 96,548 tech jobs.)

To be sure, Linux jobs continue to trail the mighty Windows, which had 16,895 listings. Linux also falls behind Unix â€“ still healthy after all these years â€“ which boasted 14,954 listings. (The AIX flavor of Unix had 2,302 jobs, and Solaris posted 4,055.)
