Black and White Thoughts

This again is not a programming tip but it was something that happend to me today, and as I found that I wanted to share it. Today I was trying to get octopress working with github pages without luck, after reloading my rvm and trying to install latest vm from I got an error getting the dependencies. 

This error was because rvm passing by default the opton -Werror-attribute which pass same option to all the native gems installed by it. So this was some sort of a bug and I had to change my local rbconfig.rb to get it fix, which I didn’t do because rubygems have a bug which I don’t know if it got solved but I reported it. So beware of this for your future rvm installations.

What I found today is what will be my new blogging platform for my programming journalism; it’s name is Octopress which is a set of modules on top of the fabulous blogging engine Jekyll which is what’s power Github Pages and works on top of Git. 

Well this is not a programming tip but it’s a good minimal project to play around in the following days I will try to migrate this blog to Octopress and play around with it. I hope to start some contributions to the project as well and learn new things to keep posting on my daily tips. 

After watching a video about doing something for 30 days I decided to give it a try, my goal for this month will be to learn something regarding programming languages in general for 30 days and making a post in here for accountability. 

Today I did not make a lot of research due to some illness in my body, but at least I learned something this is a one liner for removing the last character from each line on a file and changing it for another character in this case I needed this at work and did not want to use an editor. The thing goes a llittle bit like this:

$ ruby -pe -i.bak ‘gsub(/$\n/, “,\n”)’ file.txt

Tomorrow I’ll try to do another thing with Ruby or any other language just to keep moving things forwards.
