Perl Catalyst - VBox Network Configuration on Ubuntu

In my previous post regarding PerlCatalyst tutorial setup I mentioned about setting up a virtual machine inside a virtual machine. I didn’t provide you with much information regarding how I did it because all the tutorials related to that is already available online.

emacs - Why do I use it?

Over the past few years, the only text editor I’ve been using on Linux is emacs. Not because I wanted to. But after I joined the firm that I currently work for, I was trained in emacs.

The irony is that I am doing the BASH and Linux Basics training for new hires at my firm. I am not that bad, you see. It is just that there is so much to know.

DIR on VMS and display useful information

I don’t know if you have even heard of this operating system named OpenVMS by HP. Unfortunately or maybe fortunately I have had a chance to work on it. The operating system has a cool feature, file version is built into the OpenVMS file system. But the problem with this is that if you go into a log directory and list out files, the list could get really long. I was just trying to make it display things that I usually use on Linux....
