How to use multiple versions of Ruby in Ubuntu, Leopard and other Unix Operating Systems using RVM

Ruby Rails Ubuntu Linux Unix RVM | comments

There are many ways on how to run multiple versions of Ruby on Unix. The most simple solution is by creating a shell script.

Michael Greenly wrote a script to do just that and it worked great for me for several months.

Why I would rather go for a Karmic Koala than a Snow Leopard

Yes, there's going to be a beta release of Ubuntu 9.10 in 10 days. I am thinking about switching to use Mac but iPhone development is not something I am venturing into yet. In two months, I am just focused on early stage development of an application and I am still considering the possibility of having some new part time job.

Using Ruby for System Administration

Ruby Rails Linux | comments

What is Sytem Administration?

System Administration is a specialization in the I.T industry. These are people who handle the "dirty stuff." Some call them janitors while some call them "gods." Regardless of these perceptions, I think they play a very important role in the industry. They are not doing low-level stuff for sure. They do not care about cross-browser compatibility or making that wretched star blink in flash but they handle things that could probably matter more than you could imagine like working with enterprise data, network monitoring and handling server security. Of course, in small consulting-type companies, they are not even sought.

Adobe Flash CS4 on Ubuntu 8.10

Ok. I admit the title can be misleading. This is more of a tip for people who do flash work and cannot survive as Ruby on Rails or Python developers on a Windows machine or simply for people want to explore Linux without discarding Windows (and Mac is something they pretend they haven't heard of. Steve Jobs, throw us some Macs here. We need them).

Free Ubuntu Ebook

I have been a Windows user for a long time. I have done both design and development work on a Windows Operating System. In 2004, a good friend told me that in the long run, no matter how attached I am to my Windows OS, I will eventually switch to Linux or Mac which is true. Sometime in 2004, I also got my first Linux book from a book fare in the Baguio Convention Center. I read parts of it and it scared me how things weren't very easy. That book may still be useful on understanding Linux but only a few chapters are relevant. Things have gotten easier in Linux with so many distributions released.

Rolling back to Ruby 1.8.7 and Moving forward to Rails 2.3

Yesterday I was being slightly adventurous and decided to upgrade to Ruby 1.9.1, the first stable release of the Ruby 1.9 series. It has been a challenge trying to make Rails 2.2.2 work with Ruby 1.9.1. Check out this post.
